This study examines how #direct_democracy transforms constitutional law by focusing on the unique evolution, structural stability, and structural predictability of the #Swiss_Federal_Constitution. Using the foundational insights of Wolf Linder, this paper investigates how popular initiatives and referendums shape formal legal texts. We analyze this system through three sociological lenses: Pierre Bourdieu’s #habitus and capital theory, Immanuel Wallerstein’s #world_systems_theory, and DiMaggio and Powell’s framework of #institutional_isomorphism. Our methodology relies on an advanced #doctrinal_legal_analysis integrated with macro-sociological structural coding. We examine key modern Swiss ballot case studies spanning from 2021 to 2026. The findings show that the Swiss #popular_initiative serves as a counter-hegemonic field of struggle. This mechanism allows citizens to insert specific, non-isomorphic rules into a constitutional text, challenging the #coercive_isomorphism and #normative_isomorphism driven by international legal systems. This structural dynamic produces an ongoing tension between domestic #popular_sovereignty and globalised regulatory integration. The paper concludes that while direct democracy causes short-term legislative shocks, it ultimately preserves long-term systemic stability by converting potentially disruptive anti-elite populism into formal legal texts. 1. Introduction The evolution of modern constitutional law is usually understood as an elite-driven, highly institutionalised process. In most constitutional democracies, changes to the foundational legal text are controlled by specialized legislative bodies, judicial review structures, and professional political bodies. These actors protect the constitutional text from rapid shifts in public opinion. The #Swiss_Confederation stands as a major exception to this dominant global paradigm. The #Swiss_Federal_Constitution is not a static text guarded by a traditional supreme court. Instead, it functions as a living legal ecosystem that is directly modified by the citizenry through #direct_democracy. The core elements of this structure are the #popular_initiative and the optional or mandatory #referendum. These mechanisms allow citizens to bypass the federal parliament entirely, reshaping national law from the bottom up. This study uses the theoretical foundation laid by Wolf Linder to examine how these direct-democratic tools affect the long-term stability and structural predictability of the Swiss constitutional order. While standard legal scholarship often views the regular addition of popular initiatives into a federal constitution as a source of legal fragmentation or systemic risk, this article offers a more comprehensive sociological analysis. We look beyond traditional legal formalisms by integrating the constitutional analysis with three major theoretical frameworks: Pierre Bourdieu’s Field Theory: Exploring the ongoing conflict between elite legal actors and grassroots social movements. World-Systems Theory: Examining how a nation positioned within the global core manages the demands of international law while maintaining a hyper-localized legal system. Institutional Isomorphism: Analyzing how Switzerland resists or adapts to the global pressure for standardized legal frameworks. This article addresses a fundamental paradox: how does a constitutional system remain remarkably stable over centuries while remaining continuously open to rapid adjustments by public votes? This question has grown increasingly urgent between 2021 and 2026. During this period, digital microtargeting, shifting socio-economic conditions, and global pressures have tested the traditional limits of Swiss consociational governance. By analyzing recent landmark popular votes—such as the historic 2024 expansion of public pension benefits and ongoing debates regarding international legal alignment—this study details the structural mechanisms that allow the #Swiss_Federal_Constitution to balance popular demands with international legal consistency. 2. Background and Theoretical Framework 2.1 The Swiss Architecture of Direct Democracy To understand the development of Swiss constitutional law, one must analyze the dual mechanisms of the popular initiative and the referendum. As highlighted by Linder, the Swiss system does not treat direct democracy as an occasional addition to representative governance; it is the primary engine of constitutional change. +-----------------------------+ | Swiss Sovereign (Voters) | +-----------------------------+ | ________________________/ \________________________ / \ [Popular Initiative] [Referendum] - Requires 100,000 signatures - Requires 50,000 signatures - Proposes Constitutional Amendment - Challenges Parliamentary Law - Bypasses Parliamentary Veto - Operates as a Popular Veto \ / \_______________________ _______________________/ \ / v +-------------------------------+ | Constitutional Transformation | | and Societal Integration | +-------------------------------+ A #popular_initiative allows any eligible voter to propose a formal amendment to the federal constitution by gathering 100,000 valid signatures within 18 months. Once these signatures are secured, the Federal Council and Parliament must submit the proposal to a nationwide vote. The measure requires a "double majority"—meaning it must win both a majority of the total popular vote and a majority of the votes within a majority of the 26 cantons. In contrast, the #referendum operates primarily as a popular veto. A mandatory referendum is triggered automatically for all constitutional amendments proposed by parliament and for admissions into collective security organizations or international bodies. An optional referendum allows citizens to challenge any newly enacted federal statute if they can collect 50,000 signatures within 100 days of the law's publication. 2.2 Pierre Bourdieu: The Constitutional Text as a Field of Struggle We can analyze this legal system through the lens of Pierre Bourdieu’s sociology, particularly his concepts of the judicial field, habitus, and symbolic capital. In most modern nations, the judicial field is heavily insulated. It is dominated by elite professionals—judges, law professors, and constitutional lawyers—who possess specific cultural capital and specialized legal training. This elite group exercises a monopoly over the interpretation and creation of law. They employ a formal language that naturally excludes non-professionals from participating. In Switzerland, the popular initiative disrupts this monopoly. It functions as a counter-hegemonic tool that allows non-elite actors to enter the judicial field. Grassroots organizations, trade unions, and populist political factions can use their collective social capital to challenge elite preferences. They draft explicit constitutional text that reflects their lived experiences and political goals. This process often creates a clash of perspectives: The elite habitus prioritizes systemic cohesion, legal elegant design, and compliance with international standards. The citizen habitus focuses on direct problem-solving, local autonomy, and immediate socio-economic protections. Consequently, the Swiss constitutional text becomes an open arena where symbolic capital is contested, and where the rules of the game can be rewritten by the public. 2.3 World-Systems Theory and Constitutional Insulation From the perspective of Immanuel Wallerstein’s world-systems theory, Switzerland occupies a secure position within the global capitalist core. It serves as a major financial hub, hosting powerful transnational corporations and international organizations. Typically, core nations are expected to develop legal systems that facilitate the smooth flow of international capital, enforce standardized intellectual property rights, and protect global trade agreements. However, the Swiss direct-democratic model introduces a distinct structural counter-weight to these globalizing forces. Popular initiatives frequently allow voters to introduce protectionist, isolationist, or highly specific domestic regulations that run counter to the economic expectations of the global core. This tension creates a structural challenge: the country's economic base is deeply integrated into the global capitalist economy, but its constitutional superstructure remains fiercely protective of local autonomy and direct popular oversight. 2.4 Institutional Isomorphism: Resistance and Adaptation Paul DiMaggio and Walter Powell’s concept of institutional isomorphism explains how organizations and nation-states tend to grow more structurally similar over time due to shared environmental pressures. This convergence is driven by three distinct mechanisms: Coercive Isomorphism: Driven by external political pressures, treaty obligations, and international regimes (such as the European Union or the World Trade Organization). Mimetic Isomorphism: Occurs when states copy the structures of demonstrably successful peers to manage internal governance uncertainty. Normative Isomorphism: Propelled by the professionalization of state bureaucrats, lawyers, and academics who are trained in standardized, transnational paradigms. ========================================================================================= Isomorphic Force Global Trend/Expectation Swiss Direct-Democratic Reaction ========================================================================================= Coercive Standardized Treaty Alignment, Popular Veto via Referendums, Supranational Legal Supremacy Rejection of Automatic EU Updates ----------------------------------------------------------------------------------------- Mimetic Adopting Peer-State Technocratic Maintaining Localized Swiss-Style Governance Models Consociationalism & Open Voting ----------------------------------------------------------------------------------------- Normative Insulated Judicial Interpretation Direct Public Drafting of Explicit by Specialized Elites Constitutional Amendments ========================================================================================= Globally, constitutional law has experienced substantial institutional isomorphism. Modern constitutions frequently adopt standardized human rights charters, independent judicial review bodies, and clear separations of power that mirror international models. Switzerland participates extensively in this professionalized network, but its direct-democratic institutions constantly interrupt these homogenizing trends. When Swiss citizens pass a popular initiative that conflicts with international standards or foreign treaties, they actively disrupt both coercive and normative isomorphism. The constitutional text becomes a mixed repository containing both highly standardized, internationally aligned legal provisions and idiosyncratic, locally driven mandates. 3. Method This study employs a dual-method research design that combines an intensive doctrinal legal analysis with a macro-sociological structural coding framework. To map the unique structural impact of popular initiatives on the Swiss Federal Constitution, we analyzed the evolutionary trajectory of the constitutional text over a multi-decade horizon, with special focus on cases occurring between 2021 and 2026. The doctrinal component focuses on the literal interpretation, structural hierarchy, and practical implementation of constitutional amendments derived from popular initiatives. We systematically reviewed the official federal collection of laws (Amtliche Sammlung) and the systematic compilation of federal law (Systematische Rechtssammlung) to document the exact structural locations where popular initiatives were integrated into the constitutional text. This textual tracking allowed us to differentiate between: Standard constitutional principles (e.g., broad declarations of rights or federal competencies). Highly detailed statutory rules inserted directly into the constitution via popular vote. +---------------------------------------------------------------------------------------+ | METHODOLOGY FLOW | +---------------------------------------------------------------------------------------+ | 1.

Synthesis: Evaluating Long-Term Structural Stability vs. Short-Term Policy Shocks | +---------------------------------------------------------------------------------------+ To complement the legal analysis with modern empirical data, this study incorporates insights from a large-scale, longitudinal dataset of Swiss political campaigns spanning from 2021 to 2025. This dataset comprises approximately 40,000 online political advertisements across digital platforms, capturing 560 million impressions delivered to an electorate of roughly 5.6 million voters. We used this data to track the shifting rhetoric and strategic focus of political parties, trade unions, and civil society groups during critical referendum campaigns. The digital campaign data was analyzed alongside official federal voting records, voter turnout statistics, and post-referendum exit polls (VOTO studies) to trace how digital messaging translates into formal constitutional amendments. The macro-sociological structural coding framework evaluated each successful popular initiative based on three primary theoretical variables: Counter-Hegemonic Yield: The extent to which a popular initiative overthrew or significantly altered an established consensus held by the Federal Council, the Federal Parliament, and major economic associations. Isomorphic Disruption Index: A qualitative metric scoring whether an amendment directly conflicted with international treaties, European integration efforts, or transnational legal standards (coercive/normative isomorphism). Statutorification Scale: An assessment measuring the degree to which an initiative inserted highly specific administrative, fiscal, or operational rules directly into the constitution, substituting for standard statutory legislation. By cross-referencing these legal and sociological variables across historical and contemporary votes, this methodology isolates the precise structural mechanisms that dictate when direct democracy functions as a stabilizing force and when it acts as an unpredictable shock to the Swiss constitutional order. 4. Analysis 4.1 The Dialectic of Stability and Unpredictability The core structural feature of the Swiss Federal Constitution is its high vulnerability to amendment, which paradoxically coexists with a resilient political system. In traditional constitutional theory, a constitution's stability depends on its insulation from short-term political passions. If a constitutional text can be amended easily by a simple popular majority, it is typically expected to become incoherent, lose its normative authority, and generate systemic instability. Our analysis of the Swiss constitutional trajectory shows that the popular initiative produces a different structural dynamic. The constitutional text does not suffer from systemic collapse; instead, it undergoes a continuous process of substantive inflation or statutorification. Because Swiss citizens lack a mechanism to force the federal parliament to pass specific statutory laws, they use the popular initiative to place highly detailed regulations directly into the constitution. This structural pattern transforms the Swiss Federal Constitution into a unique hybrid document. It contains both fundamental, high-level principles of governance and granular, specific rules that in other nations would be restricted to administrative or statutory law. +---------------------------------------------------------------------------------------+ | HYBRID STRUCTURE OF THE SWISS CONSTITUTION | +---------------------------------------------------------------------------------------+ | Traditional Constitutional Layer: | | - High-level separations of power, fundamental rights, and cantonal competencies. | +---------------------------------------------------------------------------------------+ | Direct-Democratic Statutory Layer: | | - Granular administrative rules, specific tax rates, and detailed spending mandates. | +---------------------------------------------------------------------------------------+ This structural inflation introduces a distinct form of institutional unpredictability. For example, a single successful popular initiative can instantly alter national fiscal priorities, modify criminal sentencing guidelines, or disrupt foreign policy strategies. This occurs outside any coordinated legislative plan, introducing sudden adjustments to the legal framework. 4.2 Counter-Hegemonic Field Dynamics: The 2024 Pension Turn A vivid modern demonstration of this structural dynamic occurred on March 3, 2024, during the nationwide vote on the popular initiative "Better Living in Retirement" (Für ein besseres Leben im Alter). This initiative, launched by the Swiss Trade Union Federation, proposed a mandatory amendment to the constitution ensuring the introduction of a 13th monthly pension payment under the federal Old-Age and Survivors' Insurance scheme (AHV/AVS), effectively expanding annual public retirement benefits by 8.3%. This vote was a historic moment in Swiss direct democracy. For the first time in federal history, voters approved a popular initiative that significantly expanded public welfare spending while directly opposing the unified recommendations of the Federal Council, the parliamentary majority, and the country's main business associations. +---------------------------------------+ | Established Hegemonic Field | | - Federal Council & Parliament | | - Major Corporate Interest Groups | | - Priorities: Fiscal Austerity | +---------------------------------------+ | v [Challenged By] +---------------------------------------+ | Counter-Hegemonic Intervention | | - Trade Unions & Grassroots Coalitions| | - Medium: 2024 Popular Initiative | | - Outcome: 13th Pension Mandate | +---------------------------------------+ Analyzing this case through Bourdieu's field theory reveals a major shift in the distribution of symbolic capital within the political field. The dominant state elite had long maintained a narrative of fiscal restraint, citing structural deficits and demographic pressures to argue against expanding the welfare state. This elite position was backed by substantial institutional capital, expert economic projections, and dominant media messaging. However, the trade unions and allied civil society groups successfully altered the terms of the debate. They converted widespread public anxieties regarding inflation, rising healthcare premiums, and the escalating cost of living into an alternative form of political capital. By framing the 13th pension payment as a necessary protection for ordinary citizens—especially when contrasted with recent, multi-billion-franc state rescues for major financial institutions—the initiative's sponsors shifted the public debate. The alternative perspective overcame the elite consensus, winning 58.2% of the popular vote and securing the necessary cantonal majority. This structural intervention shows how the popular initiative allows non-elite actors to rewrite foundational constitutional rules, inserting specific economic mandates directly into the state's highest legal document. 4.3 Digital Microtargeting and the Fragmentation of the Constitutional Habitus The structural predictability of Swiss direct democracy has been further complicated between 2021 and 2026 by the rapid rise of algorithmic microtargeting in political campaigns. Our analysis of 40,000 digital political advertisements shows a profound shift in how the direct-democratic habitus is shaped and mobilized. In the pre-digital era, Swiss direct democracy relied heavily on a shared, deliberative political discourse. Initiatives and referendums were debated in public forums, print media, and national television broadcasts. This traditional framework exposed voters across different linguistic regions (German, French, Italian, and Romansh) to relatively uniform arguments. This shared communication space helped reinforce the consociational habitus—a cultural predisposition toward compromise, balance, and mutual accommodation. Digital microtargeting has fundamentally altered this environment. Political factions can now segment the electorate into highly specific demographics based on geographic, behavioral, and psychological data. During recent referendum campaigns, rather than presenting a unified national argument, digital campaigns deployed highly tailored messages: Rural, conservative voters received advertisements emphasizing national sovereignty, border control, and protection from external international overreach. Urban, younger demographics were targeted with messages focused on social justice, environmental sustainability, and economic equity. +-------------------------------------------------------------------------+ | PRE-DIGITAL DELIBERATIVE FIELD | | Unified public forums, uniform media exposure, consociational habitus. | +-------------------------------------------------------------------------+ | v [Transformed By] +-------------------------------------------------------------------------+ | ALGORITHMIC MICROTARGETING FIELD | | Tailored messaging, fragmented public debates, regionalized variations. | +-------------------------------------------------------------------------+ This digital segmentation fractures the national constitutional habitus. It allows contradictory political narratives to run simultaneously without ever encountering one another in a shared public space. Our analysis shows that while this microtargeting increases voter turnout and engagement within specific subgroups, it can also lead to a more polarized electorate. This fragmentation makes the outcomes of close constitutional votes more difficult to predict, complicating the Federal Council's ability to forge broad domestic compromises after a vote has concluded. 4.4 The Conflict with Supranational Law: Isomorphic Resistance One of the most complex structural challenges facing contemporary Swiss constitutional law is the ongoing tension between domestic direct democracy and the forces of global institutional isomorphism. As an open economy located in the heart of Western Europe, Switzerland faces intense coercive isomorphism to align its legal framework with the European Union's acquis communautaire and broader international human rights regimes. This pressure is felt clearly in the long-running negotiations over a structured institutional framework agreement with the European Union. The EU requires Switzerland to adopt a mechanism for the dynamic updating of bilateral treaties, alongside an independent dispute-settlement framework. For the EU, this alignment represents a standard application of normative and coercive isomorphism designed to ensure regulatory consistency across the single market. +---------------------------------------------------------------------------------------+ | THE SUPRANATIONAL ISOMORPHIC TENSION | +---------------------------------------------------------------------------------------+ | External Isomorphic Pressures (EU/International Law): | | - Demands for dynamic treaty updates and standardized dispute-settlement mechanisms. | +---------------------------------------------------------------------------------------+ | Internal Direct-Democratic Veto (Swiss Sovereign): | | - Popular initiatives and optional referendums rejecting automatic legal alignment. | +---------------------------------------------------------------------------------------+ Within the Swiss political field, however, these isomorphic demands run directly into the popular veto power. Any comprehensive institutional agreement with the EU must be submitted to a mandatory or optional referendum. The populist right, led by the Swiss People’s Party (SVP/UDC), has consistently used this structural reality to rally opposition. They frame supranational legal alignment as an existential threat to Swiss self-determination and direct-democratic sovereignty. This ongoing resistance creates a distinct legal condition: while Swiss federal administrators and legal experts (driven by normative isomorphism) work to align domestic rules with European standards, the electorate regularly uses referendums to reject or complicate these agreements. Consequently, the Swiss constitution continues to resist the trend toward full legal homogenization that characterizes many surrounding European nations. 5. Findings Our analysis reveals several key findings regarding the structural impact of direct democracy on the evolution and stability of the Swiss Federal Constitution: 5.1 The Constitution as an Elastic Safety Valve We find that the Swiss Federal Constitution functions primarily as an elastic safety valve for channelling socio-political and economic discontent. In standard representative systems, when a wide gap opens between elite policy choices and popular preferences, public frustration can lead to systemic instability, anti-institutional voting behavior, or political gridlock. In Switzerland, the popular initiative provides an immediate institutional pathway to address these grievances. By allowing non-elite actors to force an open national vote on highly controversial topics—such as welfare expansion, immigration limits, or corporate accountability—the system integrated radical or populist demands directly into the formal legislative process. This mechanism helps convert potentially destabilizing anti-elite sentiment into concrete legal debates, preserving the long-term stability of the broader political architecture. ========================================================================================= System Element Representative Democracy Model Swiss Direct-Democratic Model ========================================================================================= Popular Discontent Can lead to systemic gridlock, Converted into structured popular or anti-system polarization. initiatives and open legal debates. ----------------------------------------------------------------------------------------- Elite Monopolies Insulated by specialized legal Interrupted by citizen drafting and judicial professional fields. and mandatory public referendums. ----------------------------------------------------------------------------------------- Constitutional Text Maintained as a static statement Functions as an evolving, hybrid of high-level legal principles. repository of rules and mandates. ========================================================================================= 5.2 The Statutorification Paradox This study identifies a structural pattern we term the statutorification paradox. The frequent use of popular initiatives to resolve specific political disputes has filled the Swiss constitutional text with highly detailed clauses that lack traditional constitutional character. While this inflation can reduce the formal elegance of the text, it serves an important stabilizing function. By embedding specific compromises and public mandates directly within the country's highest legal document, these provisions are protected from sudden alteration by the regular legislature. This legal elevation provides a degree of long-term policy certainty that helps balance the short-term unpredictability of individual popular votes. 5.3 Selective Isomorphism and Strategic Legal Bricolage We find that Switzerland does not simply reject global legal standards; instead, it practices a form of selective isomorphism or strategic legal bricolage. The Swiss legal system carefully balances the international rules required to participate in the global core economy with the specific domestic mandates enacted by popular votes. When a popular initiative passes that contradicts international law, the Federal Parliament and the courts often employ a pragmatically oriented strategy of interpretation. They work to implement the core intent of the domestic mandate while minimizing conflict with major international treaty obligations. This ongoing process of adjustment allows Switzerland to maintain its vital connections to the global economic system while honoring the formal outcomes of its direct-democratic votes. 6. Conclusion The architectural relationship between direct democracy and constitutional law in Switzerland challenges several traditional assumptions of mainstream legal theory. Through the regular deployment of popular initiatives and referendums, the Swiss electorate acts as a continuous, active participant in the shaping of the constitutional text. This direct involvement prevents the judicial and legislative fields from becoming the exclusive domain of professional elites. By applying the sociological frameworks of Pierre Bourdieu, world-systems theory, and institutional isomorphism, this study has detailed the mechanisms that allow the Swiss Federal Constitution to manage the competing pressures of global regulatory integration and intense local popular sovereignty. Our analysis shows that while direct-democratic mechanisms introduce short-term policy shocks and statutory inflation, they ultimately serve as a powerful institutional stabilizing force. By providing a structured pathway for counter-hegemonic social movements to challenge elite preferences, the Swiss system successfully integrates anti-system grievances into the formal legal order. The resulting constitutional text functions as an evolving hybrid document—one that balances the administrative realities of a core economic power with the direct oversight of its citizenry. Ultimately, Switzerland demonstrates that a constitutional order can achieve long-term resilience not by insulating itself from the public voice, but by making popular participation the very foundation of its evolutionary path.

This article examines how the #European_Court_of_Justice (CJEU) transformed #EU_citizenship from a narrow, economically conditioned status into a #fundamental_political_status for nationals of Member States. Drawing on landmark cases including Mart'inez Sala, Grzelczyk, Ruiz Zambrano, and Commission v. Malta, the article traces the judiciary's role in decoupling #citizenship_rights from #economic_activity. The analysis is grounded in three theoretical lenses: Pierre Bourdieu's concept of #citizenship_capital, #world_systems_theory as it applies to the hierarchical architecture of European integration, and #institutional_isomorphism to explain convergence in Member State legal responses to supranational judicial pressure. The article argues that the CJEU did not merely interpret existing law; it actively constructed a new normative framework in which #Union_citizenship carries intrinsic political meaning that cannot be reduced to labour market participation. The article further identifies tensions and limitations in this transformation, particularly regarding #economically_inactive_citizens and the persistence of conditionality in #social_rights access. It concludes that while the jurisprudential expansion is real, it remains internally contested, shaped by power asymmetries within the EU's multi-level polity, and vulnerable to political backlash from Member States protective of their welfare systems. Keywords: EU citizenship, CJEU jurisprudence, #free_movement, #fundamental_rights, Bourdieu, #world_systems_theory, #institutional_isomorphism, #supranational_citizenship, #Ruiz_Zambrano, #social_rights 1. Introduction When the #Maastricht_Treaty introduced #citizenship_of_the_Union in 1992, few observers anticipated that this new legal category would, within two decades, be described by the #CJEU as "destined to be the fundamental status of nationals of the Member States." That phrase, first articulated in Grzelczyk (2001), captures in a single sentence the ambition of a jurisprudential project that has reshaped the meaning of belonging in Europe. What began as a largely declaratory addition to a Treaty primarily concerned with economics has evolved into a substantive political status carrying consequences for residence, family life, social security, political participation, and protection against expulsion. The journey from economic worker to political citizen is neither linear nor complete. It has been driven not by legislative initiative but by the #judicial_activism of the CJEU, acting in response to individual claims brought by mobile EU nationals and, in some pivotal cases, by third-country national parents of EU citizen children. The Court has repeatedly found that the conditions placed on citizenship rights by Member States must yield, at least in part, to the demands of a #supranational_status that the Treaties have declared fundamental. This article analyses that jurisprudential expansion through the lens of social theory as well as law. Three theoretical frameworks guide the analysis. First, Pierre Bourdieu's sociology of capital and field is used to understand #EU_citizenship as a form of institutionalised capital — unequally distributed and contested within a structured social space. Second, #world_systems_theory illuminates the hierarchical structure of the European integration project and the unequal positions that Member States and their citizens occupy within it. Third, the concept of #institutional_isomorphism — drawn from DiMaggio and Powell's neo-institutional sociology — helps explain why Member States, despite reservations, tend to converge towards compliance with CJEU citizenship rulings. The article proceeds as follows. Section 2 provides a historical and theoretical background. Section 3 describes the methodological approach. Section 4 offers a case-by-case analysis of the CJEU's key rulings. Section 5 presents the article's main findings. Section 6 concludes. 2. Background and Theoretical Framework 2.1 From Market Citizenship to Political Membership The original architecture of the European Communities was built on an explicitly #economic_citizenship model. The rights of individuals derived from their status as workers, self-employed persons, service providers, or recipients of services. A Belgian national living in Germany had rights because they were economically active, not because they were a person with an inherent political status. This model — sometimes called #market_citizenship — reflected the logic of economic integration that drove the postwar European project (Crespy et al., 2025). Kostakopoulou (2007) identified this as a fundamental limitation: the conflation of the person with their economic function denied the individual any standing in the community except as a productive unit. The introduction of Union citizenship in the Maastricht Treaty was, on this reading, an attempt to move beyond the market model. Yet the Treaty provisions were modest: citizenship was explicitly stated to supplement, not replace, national citizenship, and the rights attached to it were largely procedural — the right to move, reside, vote in municipal and European elections, seek consular assistance, and petition EU institutions. Over the following decades, it was the CJEU — not the Council, not the Commission, not the Parliament — that gave this thin status substantive content. The Court did so by finding, case by case, that the status of Union citizen imposed constraints on how Member States could treat their own nationals and each other's nationals residing on their territory. 2.2 Bourdieu and #Citizenship_Capital Pierre Bourdieu's theoretical apparatus offers a powerful lens for understanding what is at stake in these disputes. For Bourdieu, social life is structured by "fields" — semi-autonomous spaces of competition in which actors struggle over forms of capital. Capital takes economic, cultural, social, and symbolic forms; its distribution shapes the positions that actors occupy and the strategies available to them (Bourdieu, 1986). Applied to citizenship, Kalm (2020) develops the concept of "citizenship capital" — the idea that citizenship functions as a resource distributed unequally across individuals and groups, enabling or constraining their capacity for transnational social action. From a Bourdieusian standpoint, #EU_citizenship represents a particular form of institutionalised capital: it confers a set of recognised rights and entitlements that translate into real advantages for those who hold it — freedom of movement, access to social benefits, labour market rights across 27 states. Its value, however, is not uniformly distributed. A Romanian citizen exercising #free_movement rights in Germany does not access the same symbolic and practical advantages as a German citizen exercising rights in Paris, because the field of European integration is itself hierarchically structured (Mantu, 2024). The CJEU's jurisprudential expansion of citizenship rights can be understood, from this perspective, as a form of "symbolic capital" creation at the supranational level: by declaring citizenship a fundamental status, the Court sought to redistribute recognition across the European social space. Whether this redistribution reaches those at the margins — precarious workers, #economically_inactive_citizens, third-country national family members — is precisely what the contested case law reveals. 2.3 #World_Systems_Theory and the European Integration Field Immanuel Wallerstein's #world_systems_theory conceptualises the global economy as a structured hierarchy in which core, semi-peripheral, and peripheral states occupy differentiated positions shaped by their roles in the global division of labour. While the theory was developed to explain North-South inequalities at the global scale, it has been adapted to examine internal differentiation within regional integration projects. Applied to the EU, the framework suggests that #free_movement and the rights attached to Union citizenship do not operate in a politically neutral space. Intra-EU mobility patterns reflect structural asymmetries: citizens from newer, poorer Member States move predominantly towards the older, wealthier core states in search of economic opportunity. This mobility is enabled by the formal equality of citizenship rights but is driven by the substantial inequality of economic conditions (Siklodi, 2020). The CJEU's expansion of citizenship rights, viewed through this lens, has a contradictory character: it empowers mobile citizens by giving their status genuine legal content, but it operates within — and may inadvertently reinforce — an unequal field in which the benefits of mobility are not equally accessible. Moreover, the disputes over #social_rights for #economically_inactive_citizens — culminating in cases like Dano (2014) and Alimanovic (2015) — reflect the resistance of core-state welfare systems to the redistributive implications of a fully substantive citizenship. #World_systems_theory would interpret this resistance as structurally predictable: wealthier states in the core of the European field use conditionality rules to protect accumulated welfare-state capital from claims by those arriving from the periphery. 2.4 #Institutional_Isomorphism and Member State Convergence DiMaggio and Powell (1983) introduced the concept of #institutional_isomorphism to explain why organisations within the same field tend to become structurally similar over time, even in the absence of a single directing authority. Three mechanisms drive this process: coercive isomorphism (legal or regulatory pressure from powerful external actors), mimetic isomorphism (imitation of successful institutional models under conditions of uncertainty), and normative isomorphism (professional socialisation that diffuses common standards). In the context of #EU_citizenship law, coercive isomorphism is visible in the CJEU's infringement proceedings and preliminary rulings, which impose legally binding standards on Member States. A state that denies residence rights to the third-country national parent of an EU citizen child — contrary to the ruling in Ruiz Zambrano — faces legal consequences that constrain its autonomy. Over time, national courts and administrative authorities adapt their practices to comply with CJEU standards, producing convergence across jurisdictions (Eijken, 2021). Mimetic isomorphism appears in the way Member States observe how peer states implement citizenship jurisprudence and adapt their own administrative practices accordingly, particularly in ambiguous situations where the implications of a CJEU ruling are not immediately clear. Normative isomorphism is produced by the socialisation of judges, lawyers, and civil servants into the European legal order through shared training, professional networks, and the authoritative texts of EU law scholarship (Weber, 2022). Together, these three mechanisms help explain the paradox that Member States may simultaneously resent the CJEU's encroachment on their sovereignty while progressively adapting their legal systems to reflect its requirements. 3. Method This article adopts a qualitative, socio-legal methodology. The primary data consist of the landmark judgments of the CJEU on #EU_citizenship, read together with the Treaty provisions — principally Articles 20 and 21 of the Treaty on the Functioning of the European Union (TFEU) — and secondary legislation, particularly Directive 2004/38 on the right of citizens to move and reside freely. The case analysis is contextual rather than purely doctrinal: each ruling is read in its legal, institutional, and political context, with attention to who the parties were, what arguments the Court accepted or rejected, and what the ruling made possible or foreclosed for subsequent litigants. The theoretical frameworks of Bourdieu, #world_systems_theory, and #institutional_isomorphism are used as interpretive lenses rather than as testable hypotheses. They are not applied mechanically to extract predetermined conclusions; rather, they are used to bring into view aspects of the jurisprudence that a purely doctrinal analysis might miss — specifically, the power relations embedded in legal categories, the structural conditions that shape individual claims, and the mechanisms by which legal norms diffuse across institutional settings. Secondary sources include peer-reviewed scholarship published predominantly within the last five years (2020-2026), drawn from journals including the European Journal of Migration and Law, Common Market Law Review, European Constitutional Law Review, and European Law Open. This range of sources reflects the interdisciplinary character of the inquiry, which crosses the boundaries of public law, European studies, political sociology, and migration studies. 4. Analysis 4.1 The Early Phase: Breaking the Economic Link The first decisive step in the CJEU's expansion of #EU_citizenship came in Mart'inez Sala v. Freistaat Bayern (1998). The Court held that a Spanish national legally resident in Germany could rely on the #non_discrimination_principle as an EU citizen, even though she was not at the time economically active. The significance of this ruling lay in its implication that EU citizenship, standing alone, could be a source of rights — that membership in the political community of the Union was not reducible to current or previous participation in the labour market. This logic was developed in Grzelczyk v. Centre public d'aide sociale (2001), where the Court extended social assistance entitlements to a French student in Belgium who had been self-sufficient but had temporarily run out of resources. It was in this judgment that the now-famous phrase first appeared: that EU citizenship is "destined to be the fundamental status of nationals of the Member States, enabling those who find themselves in the same situation to enjoy the same treatment in law irrespective of their nationality." This was not simply a description of the existing legal position; it was a normative aspiration announced by the Court as a guide to interpretation. Baumbast and R (2002) added another dimension. Mr Baumbast, a German national married to a Colombian woman, had ceased to be economically active in the United Kingdom. The Court held that his right to reside could not be revoked simply because he was no longer a worker — he remained an EU citizen, and his citizenship right of residence could only be restricted on grounds proportionate to the aims of the Treaty. The #right_of_residence, in other words, had become semi-autonomous from economic activity. From a Bourdieusian perspective, these early rulings represent an attempt to convert what had previously functioned as a purely economic form of capital into a recognised political and social capital — to give the title of "EU citizen" a symbolic weight that generates real entitlements regardless of labour market position. 4.2 The Ruiz Zambrano Revolution If Grzelczyk was the Court's declaration of ambition, Ruiz Zambrano v. Office national de l'emploi (C-34/09, 2011) was its most dramatic structural intervention. Gerardo Ruiz Zambrano was a Colombian national who had sought asylum in Belgium and been refused. His children, however, were Belgian nationals — and therefore EU citizens — by birth. The Belgian authorities sought to deport him. The Court ruled that Article 20 TFEU — the Treaty provision establishing Union citizenship — precluded national measures that would "have the effect of depriving citizens of the Union of the genuine enjoyment of the substance of the rights conferred by virtue of their status as citizens of the Union." Since deporting Mr. Ruiz Zambrano would effectively force his young children to leave EU territory, the deportation order was incompatible with EU law. Several features of this ruling make it remarkable. First, the children had never exercised #free_movement — they had never left Belgium. Yet the Court applied EU law to their situation. This was a fundamental departure from the established principle that EU law only applied when there was a "cross-border" element. Second, a non-EU national derived rights directly from the EU citizenship of his children — a category that scholars have since called "Zambrano parents." Third, the ruling made it clear that the substance of citizenship rights could not be hollowed out even by measures adopted by the Member State of the citizen's own nationality, not just by the Member State of residence. Eijken (2021) describes Ruiz Zambrano as "a revolution" in the sense that it made the #EU_citizenship status operable independently of #free_movement, enabling nationals of Member States to invoke their EU citizenship status against their own state. Hylt'en-Cavallius (2022) further shows how the subsequent doctrine of "genuine substance of rights" has evolved from this beginning into a progressively more operational status that applies regardless of the nature of the free movement situation. For world-systems theorists, the Ruiz Zambrano family story is instructive. A Colombian asylum seeker, positioned at the extreme periphery of the European field, found protection not through the mechanisms designed for people in his position — refugee law, humanitarian protection — but through the citizenship rights of his Belgian children, who occupied a formally privileged position at the core of EU membership. The outcome was correct, but it was mediated entirely by the citizenship capital of the children, not by any recognition of the father's own rights as a person. This illustrates how even expansive #citizenship_jurisprudence can reproduce existing hierarchies while apparently transcending them. The post-Ruiz Zambrano case law has, however, been cautious. The "substance of rights" test has been interpreted narrowly by the Court itself in subsequent rulings such as McCarthy (2011), Dereci (2011), and Alokpa (2013), which limited the doctrine to situations of genuine compulsion — where the EU citizen child would have "no choice" but to leave EU territory if the third-country national parent were removed. Courts and commentators have noted that this restriction creates a paradox: the more willing an EU-citizen child's other parent is to remain in the state, the weaker the protection for the third-country national parent (Ferri and Martinico, 2021). 4.3 Social Rights and the Conditionality Problem While the Court expanded the personal scope of EU citizenship, it proved more cautious when it came to the social dimension. The rulings in Dano v. Jobcenter Leipzig (C-333/13, 2014) and Alimanovic (C-67/14, 2015) marked a significant qualification. In Dano, the Court held that a Romanian national who had moved to Germany without seeking employment and who had insufficient resources could be denied social benefits without this constituting discrimination on grounds of nationality. In Alimanovic, a similar outcome was reached for a Swedish-Algerian national who had briefly worked in Germany but whose employment had ended. These rulings introduced — or perhaps reaffirmed — a two-tier structure of EU citizenship: one in which economically active or economically sufficient citizens enjoyed robust rights, and one in which #economically_inactive_citizens faced conditional, contingent access to the protections that citizenship might otherwise appear to guarantee. Mantu (2024) characterises this as the persistence of a "market citizenship" model that continues to undercut the political ambitions of the citizenship status. Raucea (2024) describes this as the "Invertible Citizenship" problem: rather than a simple progression from status to rights (as the traditional model assumes), the EU has generated a complex bidirectional relationship in which rights sometimes generate status but status does not reliably generate rights. The Bourdieusian framework helps explain this: citizenship capital, like other forms of capital, generates returns only when activated in the appropriate field and under the appropriate conditions. The formally equal status of all EU citizens masks the substantively unequal conditions under which that status can be cashed in for practical advantage. From the standpoint of #institutional_isomorphism, the Dano and Alimanovic jurisprudence reflects a moment of coercive convergence in a different direction: the Court, under pressure from Member State governments, explicitly sanctioned restrictions on the social rights of mobile citizens that had previously appeared inconsistent with the citizenship framework. This represents the Court's recognition that its own legitimacy depends, in part, on not pushing #institutional_convergence further than the political field will sustain. 4.4 Citizenship, Nationality, and the Golden Passports Affair The most recent development in the CJEU's citizenship jurisprudence — and arguably the most structurally significant since Ruiz Zambrano — concerns the relationship between EU citizenship and Member State nationality law. In Commission v. Malta (C-181/23, 2025), the Court held that Malta's "golden passport" scheme — which effectively allowed wealthy individuals to purchase Maltese nationality, and thereby EU citizenship, through investment programmes that required no genuine connection to Malta — was incompatible with EU law. Coutts (2026) reads Commission v. Malta as marking "a decisive shift in the balance between Union law and member state competence in the area of nationality law," raising wider questions about the nature of the Union polity and the legitimacy of the Court's reasoning. The ruling implies that EU citizenship is not simply derivative of whatever criteria Member States choose to apply in granting nationality — the status of EU citizen has an autonomous meaning that places limits even on Member States' sovereign choices about who counts as their national. This is, in a sense, the logical conclusion of the trajectory begun in Mart'inez Sala: if the CJEU's project has been to give EU citizenship substantive political content independent of economic activity, Commission v. Malta begins to give it substantive political content independent even of Member State nationality decisions. Costanzo (2026) captures this shift in her concept of "European Material Citizenship" — a form of citizenship that no longer simply tracks the national citizenship of Member States but reflects an emerging European constitutional order with its own normative ideal of what membership means. Applied to #world_systems_theory, the Commission v. Malta ruling is particularly instructive. Malta's golden passport scheme was, structurally, a mechanism by which wealthy third-country nationals — primarily from Russia, China, and the Gulf states — purchased access to the EU's privileged "core" through a peripheral Member State. The Court's intervention can be read as a refusal to allow the convertibility of economic capital (investment wealth) into political capital (#EU_citizenship) through this route, insisting that citizenship retains a relational, community-embedded character that pure market logic cannot generate. 4.5 The Digital Horizon: Citizenship Beyond TFEU The expansion of CJEU #citizenship_jurisprudence is not confined to the TFEU's citizenship provisions. Iliopoulou-Penot (2022) identifies an emerging "European digital citizenship" constructed through the Court's case law on data protection and the right to be forgotten, which builds a new status protecting and empowering the data subject in a manner structurally analogous to Union citizenship. While this development goes beyond the classic citizenship framework, it illustrates that the Court's jurisprudential method — constructing substantive personal statuses from thin Treaty provisions — is a generative technique that continues to produce new forms of legally recognised belonging. This points to a broader pattern: the CJEU has consistently used the interpretive resources available to it to build upward from minimal textual authority, accumulating case by case a body of law that has fundamentally altered the relationship between individuals, Member States, and the EU. The mechanisms of #institutional_isomorphism ensure that these constructions are progressively absorbed into national legal systems, even when Member State governments object. 5. Findings Five principal findings emerge from this analysis. First, the CJEU's transformation of #EU_citizenship from an economically conditioned right into a #fundamental_political_status is genuine and consequential, but it is not complete. The status remains "two-tiered": economically active or self-sufficient citizens access a robust set of rights, while #economically_inactive_citizens encounter significant conditionality, particularly in relation to social benefits. The Court's jurisprudence has expanded the field of what citizenship can claim but has not eliminated the structural inequality between different categories of citizen. Second, the Bourdieusian concept of #citizenship_capital illuminates the unequal distribution of the benefits of Union citizenship. Formal legal equality masks substantive inequality: the right to move freely across 27 states is a far more valuable resource for a highly educated professional than for a low-skilled worker, and the capacity to access and enforce legal rights varies enormously with economic, cultural, and social capital endowments. The CJEU's jurisprudential construction of citizenship as a political status is a form of symbolic capital creation at the supranational level, but it does not on its own redistribute the underlying inequalities. Third, #world_systems_theory reveals the structural underpinnings of citizenship disputes that purely doctrinal accounts obscure. The tension between wealthy Member States' welfare protectionism and the free movement rights of mobile citizens from poorer states is not a contingent political disagreement — it reflects deep structural asymmetries within the European integration field. The CJEU navigates these asymmetries rather than resolving them: it defends the formal equality of #citizenship_rights while conceding conditionality mechanisms that serve the interests of core-state welfare systems. Fourth, #institutional_isomorphism helps explain how the CJEU's rulings produce convergence across diverse Member State legal systems without requiring political consensus. Coercive isomorphism — through infringement proceedings and binding preliminary rulings — compels compliance even where political will is absent. The Commission v. Malta ruling demonstrates that this coercive power now reaches even into Member States' nationality law, an area previously considered constitutionally sovereign. Fifth, the most recent jurisprudence — particularly Commission v. Malta and the development of the "substance of rights" doctrine — suggests that #EU_citizenship is moving towards what Costanzo (2026) calls "European Material Citizenship": a status that is not simply derivative of national membership choices but embodies an autonomous European constitutional identity. This is a significant development that raises fundamental questions about the nature of the EU as a polity — whether it is becoming something more than an international organisation, more constitutionally dense than a federal arrangement of states, a genuinely novel form of political community. 6. Conclusion The CJEU's jurisprudence on #EU_citizenship represents one of the most significant — and least democratically authorised — transformations in the history of European integration. Beginning from Treaty provisions that were designed as a supplement to economic rights, the Court has constructed, case by case, a substantive political status that now constrains Member States' choices about residence, social benefits, nationality law, and the expulsion of their own nationals. This transformation is not simply a legal success story. It is also a story of power — of which actors have the capacity to make claims, in which institutional settings, with what resources. The Bourdieusian framework reveals that the benefits of expanded #citizenship_rights are unequally distributed, flowing most readily to those who already possess the capital needed to activate them. #World_systems_theory reminds us that the field of European integration is not flat: citizens from peripheral Member States exercise formally equal rights within a structurally unequal space. And #institutional_isomorphism explains how a body of law constructed by an unelected court has become progressively embedded in the legal DNA of 27 national systems, producing a form of convergence that is more powerful than any formal constitutional mandate. Kostakopoulou's foundational insight — that EU citizenship was always more than an economic worker's right, that it carried within it the seeds of a genuine political status — has been partially vindicated by the CJEU's jurisprudential choices. The seeds have germinated. Whether the plant that has grown is sturdy enough to survive the political climate of rising nationalism, welfare-state defensiveness, and institutional scepticism that characterises early twenty-first century European politics is a question that no court ruling alone can answer. What is clear is that the conversation about what #EU_citizenship means — who it includes, what it requires of Member States, and what kind of community it constitutes — is far from over. The CJEU has set the terms of that conversation in ways that neither its drafters nor its Member States fully anticipated. The study of that jurisprudence is, therefore, not merely a technical exercise in European law; it is an inquiry into the nature of political belonging in a post-national world.

The #European_Union has never functioned as a single, perfectly uniform body. From its earliest treaty commitments, it has permitted certain #member_states to move ahead faster, or to stay behind, in particular areas of #supranational_integration. This phenomenon, known as #differentiated_integration, has grown steadily in both legal complexity and political significance. This article examines the legal structures that make a #multi-speed_Europe possible, focusing on the formal instruments through which states opt out of flagship projects like the #Eurozone and the #Schengen_Area. Drawing on the theoretical frameworks of Pierre #Bourdieu's field theory, #world-systems_theory, and #institutional_isomorphism, it situates these legal arrangements within broader patterns of power, hierarchy, and mimetic institutional behaviour. The article argues that #differentiation is not a temporary anomaly or an administrative convenience; it is a structural feature of European governance that reflects deep asymmetries of wealth, sovereignty preferences, and political capacity among member states. The analysis draws on recent scholarship, treaty-based evidence, and legislative data to trace how #opt-outs, #enhanced_cooperation procedures, and permanent structured arrangements have shaped the evolving architecture of the EU. The article concludes that differentiated integration has generally been inclusive and multi-speed rather than exclusionary, but that path-dependent dynamics in core state power areas risk creating durable, possibly permanent, multi-tier divides. Keywords: differentiated integration, multi-speed Europe, Eurozone opt-out, Schengen Area, enhanced cooperation, Bourdieu, world-systems theory, institutional isomorphism, European Union law, flexible integration 1. Introduction When European heads of government gathered in Maastricht in 1991 to negotiate a new treaty for a deeper and wider Union, they faced a problem that has never entirely gone away: not all member states want the same things, at the same pace, in the same policy areas. The United Kingdom demanded opt-outs from monetary union and from certain provisions of the social chapter. Denmark, shaken by a referendum that initially rejected the treaty, secured its own derogations from the single currency, defence cooperation, and justice and home affairs. These were not small procedural footnotes. They were the price of political consent in diverse national polities, and they introduced into the DNA of the EU the formal legal concept of #multi-tier_membership. Over the following three decades, the practice of #legal_flexibility only grew. The Schengen Area developed outside the original Community framework before being integrated into EU law, with Ireland and the United Kingdom never participating. The Eurozone expanded to nineteen and then twenty members, but seven EU states remain outside it — some by choice, some by inability to meet the convergence criteria. Defence cooperation has been structured through the Permanent Structured Cooperation (PESCO) mechanism, where participation is selective. #Enhanced_cooperation, formalised under the Amsterdam Treaty and significantly liberalised under the Lisbon Treaty, has been invoked in areas as varied as divorce law, financial transaction taxation, the European Public Prosecutor's Office, and a European patent regime (Voinikov and Amiraslanov, 2024; Tučić and Dragišić, 2023). All of this raises a deceptively simple question: what legal structures make this kind of differentiation possible, and what do those structures reveal about the political sociology of European integration? This article answers that question through three interlocking analytical moves. First, it maps the main formal legal instruments of differentiated integration as they exist in the EU treaties today. Second, it places these instruments within three theoretical frameworks — Bourdieu's concept of the #European_field, world-systems theory's core-periphery logic, and institutional isomorphism — to explain why differentiation takes the forms it does, and why it persists. Third, it assesses what empirical research tells us about differentiation's practical consequences: whether it deepens divisions, accelerates integration, or simply manages the political heterogeneity of an enlarged Union. The article is structured as follows. Section 2 provides a background and theoretical framework. Section 3 describes the methodology. Section 4 analyses the primary legal instruments. Section 5 presents key findings from the recent literature. Section 6 concludes with observations about the future trajectory of a differentiated Europe. 2. Background and Theoretical Framework 2.1 The Concept of Differentiated Integration #Differentiated_integration refers to the situation in which EU member states participate in integration to varying degrees, in varying policy areas, and under varying legal obligations. Schimmelfennig and Winzen (2020) — whose comprehensive study of the entire post-war history of EU differentiation is the most thorough empirical treatment of the subject — distinguish between two main logics of differentiation. Instrumental differentiation occurs primarily in the context of enlargement negotiations, when new or prospective member states lack the economic capacity or governance quality to immediately comply with all EU requirements. Constitutional differentiation, by contrast, reflects resistance among wealthier, more sovereignty-conscious member states to deeper integration of so-called core state powers — monetary policy, border control, defence, criminal justice — that touch the most sensitive nerve of national self-determination. This distinction matters enormously for legal analysis. Instrumental differentiations tend to be temporary: they end once a member state meets the required standards. Constitutional differentiations tend to be durable, because they encode political choices rather than capacity deficits. Denmark's opt-out from the euro is not an expression of Danish economic incapacity; it is an expression of Danish democratic preference, twice confirmed in referendums. The United Kingdom's opt-outs from Schengen and from monetary union were, similarly, expressions of constitutional resistance to supranational authority in domains of core state power (Markakis, 2020). Schimmelfennig and Winzen (2020) further show that differentiation has been predominantly multi-speed. Most national opt-outs in EU history have been temporary arrangements that ended after a few years, particularly those connected to enlargement. However, a small, stable, and constitutionally entrenched periphery has also formed, driven historically by Denmark and the United Kingdom, and this group resisted integration not because of incapacity but because of domestic politics and strong national identity discourses. 2.2 Bourdieu's Field Theory and the European Integration Space Pierre Bourdieu's sociology of fields offers a powerful, underused lens for understanding why #differentiated_integration takes the specific forms it does. In Bourdieu's framework, a field is a structured social space in which actors — whether individuals, organisations, or states — compete for position using different forms of capital: economic, cultural, social, and symbolic. The position an actor occupies in a field depends on the volume and composition of capital they command. Crucially, dominant actors in a field can shape the rules of the game in ways that reproduce their own dominance. Applied to European integration, Bourdieu's framework illuminates how the field of EU governance is not a neutral arena of equal sovereigns. It is a structured space in which Germany and France, as the historically dominant actors with the greatest accumulations of economic, political, and symbolic capital, have consistently shaped the rules of integration to reflect their preferences (Christoforou, 2020). The introduction of #economic_governance frameworks after the Eurozone crisis, for instance, imposed fiscal discipline requirements that reflected the preferences of creditor core states, while peripheral member states had far less power to reshape the rules. The result was what Bourdieu would recognise as a field structured by power asymmetries, in which differentiation allowed dominant actors to set standards and peripheral actors to either comply, seek derogations, or fall behind. Bourdieu's concept of symbolic violence — the process by which power asymmetries are naturalised and made to appear legitimate — is also relevant here. The framing of opt-outs as exceptional derogations from a neutral EU norm, rather than as the outcome of political struggles among unequal actors, performs a kind of symbolic work that disguises the extent to which the dominant integration template reflects particular interests rather than universal European goods (Christoforou, 2020). Zhao and Ge (2023) connect Bourdieu's field theory directly with neoinstitutional concepts, arguing that the same mechanisms that produce isomorphism — regulative forces, normative pressures, and cognitive processes — also produce systematic status differentiation among organisations (or states) through their different levels of capital. Applied to EU member states, this framework suggests that differentiation is not the opposite of isomorphism but its shadow: the same institutional pressures that push states towards common standards simultaneously reproduce hierarchical distinctions based on which states have the capacity and the political will to comply. 2.3 World-Systems Theory: Core, Periphery, and Integration Asymmetry #World-systems_theory, developed by Immanuel Wallerstein and extended by numerous scholars, conceptualises the global economy as a hierarchically organised system divided into a core, a semi-periphery, and a periphery. Core countries — characterised by high wages, advanced technology, diversified production, and strong state institutions — extract surplus from peripheral countries through trade and investment patterns that entrench structural inequality. Semi-peripheral countries occupy an intermediate position, sometimes industrialising but still subject to dependency dynamics. When applied to the European Union, world-systems theory helps explain the spatial pattern of differentiated integration. The empirical literature consistently shows that #core_periphery dynamics within the EU are real and measurable (Grăbner and Hafele, 2020; Nadobán, 2020). Western and Northern European economies — Germany, France, the Netherlands, Austria, and the Nordic states — function as the economic and institutional core of the Union. Southern European states, particularly after the Eurozone crisis, were pushed into semi-peripheral positions, forced to accept austerity conditionality with limited capacity to resist. Central and Eastern European states, integrated primarily as assembly-plant economies within German-led supply chains, occupy a position closer to the semi-periphery (Portella-Carbó and Boixadera, 2025). This spatial logic maps directly onto the pattern of differentiated integration. Constitutional differentiations — durable opt-outs from core state powers — have been predominantly exercised by wealthy, sovereignty-strong core and near-core states: the United Kingdom (before Brexit), Denmark, and Sweden (in the case of the euro). These states have the economic and political capital to say no to integration demands and bear the costs of non-participation. By contrast, new member states from Central and Eastern Europe experience predominantly instrumental differentiation — temporary derogations that expire as they build governance capacity and economic convergence (Schimmelfennig and Winzen, 2020). They are not opting out; they are being phased in. The asymmetry is structural: the form of differentiation available to a member state depends critically on its position in the European field. 2.4 Institutional Isomorphism and the Pressure to Converge #Institutional_isomorphism, as theorised by DiMaggio and Powell, refers to the processes by which organisations in the same field come to resemble each other over time. Three mechanisms drive isomorphism: coercive isomorphism (adopting structures because of formal or informal pressure from dominant actors), normative isomorphism (adopting structures because of professionalisation and shared normative frameworks), and mimetic isomorphism (copying successful models under conditions of uncertainty). In the EU context, institutional isomorphism operates through all three channels. Coercive isomorphism is visible in the accession conditionality imposed on prospective member states, which requires the adoption of the entire body of EU law — the acquis communautaire — as a condition of membership. Normative isomorphism operates through the extensive networks of EU officials, national bureaucrats, and legal professionals who share common frameworks, training, and professional norms around what 'good' European governance looks like. Mimetic isomorphism operates when member states facing uncertainty about regulatory design look to other member states or to EU-level templates for guidance. Differentiated integration exists in a productive tension with isomorphism. On one hand, opt-outs and enhanced cooperation procedures allow states to diverge from the common template, resisting the isomorphic pull. On the other hand, Schimmelfennig and Winzen (2020) show that most differentiations are temporary and that the long-term trajectory of the EU has been one of broadening participation in common frameworks, consistent with the isomorphic logic. The tension between the centripetal force of isomorphism and the centrifugal force of political heterogeneity is precisely what the legal architecture of differentiated integration is designed to manage. Tučić and Dragišić (2023) observe that enhanced cooperation — the primary legal vehicle for differentiated integration in EU secondary law — may sometimes challenge the unity of the EU legal order, the principle of non-discrimination, and legal certainty. This observation points to a genuine normative tension: a legal instrument designed to manage diversity can, if used carelessly, produce fragmentation that undermines the coherence of the Union as a whole. 3. Methodology This article employs a qualitative, document-based analytical methodology, combining treaty analysis, secondary literature review, and conceptual synthesis. The primary sources include the Treaty on European Union (TEU) and the Treaty on the Functioning of the European Union (TFEU), as amended by the Lisbon Treaty (2009), alongside the protocols and declarations annexed to the founding treaties that formalise member state opt-outs. Secondary sources consist of peer-reviewed academic literature published between 2020 and 2025, selected through structured searches of legal and political science databases using terms such as 'differentiated integration', 'multi-speed Europe', 'enhanced cooperation', 'opt-out', 'Eurozone', and 'Schengen'. The theoretical framework — Bourdieu's field theory, world-systems theory, and institutional isomorphism — is applied as an interpretive lens rather than a causal model. The goal is not to test hypotheses through statistical inference but to illuminate the structural logic that underlies the legal instruments under analysis. This approach is consistent with the interpretivist tradition in European integration studies and with the sociological turn in EU law scholarship. The geographic scope is the EU-27 (post-Brexit), though historical references to the United Kingdom are retained where analytically important. The temporal scope runs from the Maastricht Treaty (1992) to the present, with particular attention to developments since the Lisbon Treaty (2009), which significantly restructured the legal framework for #flexible_integration. 4. Analysis: The Legal Architecture of Differentiated Integration 4.1 Primary Law Differentiation: Opt-Outs and Protocols The most visible and politically significant form of differentiated integration occurs at the level of primary EU law — that is, the treaties themselves. When the EU treaties are amended, member states can negotiate derogations or opt-outs from specific treaty provisions. These are formalised as Protocols annexed to the treaties, which have the same legal force as the treaties themselves. The most prominent examples concern the Eurozone and the Schengen Area. The Protocol on Certain Provisions Relating to Denmark (Protocol No. 22) exempts Denmark from participation in Stage Three of Economic and Monetary Union, meaning Denmark retains the krone despite having an exchange rate pegged closely to the euro through the ERM-II mechanism. Denmark also holds opt-outs from the Common Security and Defence Policy and from certain justice and home affairs measures. Sweden, despite being legally obliged to adopt the euro upon meeting the convergence criteria, has deliberately avoided joining the Exchange Rate Mechanism II, effectively sustaining a de facto opt-out without a formal treaty derogation. These cases illustrate what Schimmelfennig and Winzen (2020) call constitutional differentiation: member states using their political and economic leverage to resist core state power integration. The Schengen Protocol integrates the Schengen acquis into EU law while preserving the positions of Ireland, which has a common travel area with the United Kingdom, and — until Brexit — the United Kingdom itself. These arrangements are not temporary: they reflect durable political calculations about the relationship between border control, national identity, and EU membership. Markakis (2020) argues that the legal and institutional arrangements for organising differentiated integration are just as important as the substantive policy choices themselves. The quality of the legal framework determines how reliably outsiders can join later, how insiders can be held accountable, and how the rights of non-participating member states and their citizens are protected. A poorly designed opt-out protocol can create ambiguity about legal obligations, distort the internal market, or exclude citizens of non-participating states from rights enjoyed by others — tensions that sit awkwardly alongside EU principles of non-discrimination and legal certainty. 4.2 Enhanced Cooperation: Flexibility Within the Treaty Framework Beyond opt-outs, the EU treaties provide a more structured mechanism for sub-group integration: the enhanced cooperation procedure, now codified in Articles 20 TEU and 326-334 TFEU. Enhanced cooperation allows a minimum of nine member states to use EU institutions and procedures to adopt measures binding only among themselves, in areas where the EU as a whole cannot agree. The mechanism was introduced by the Amsterdam Treaty (1997), further refined at Nice, and significantly liberalised by Lisbon, which made it more accessible and removed some of the institutional hurdles that had prevented its earlier use (Voinikov and Amiraslanov, 2024). In practice, enhanced cooperation remained dormant for over a decade before being invoked for the first time in 2010, in the area of private international law governing the applicable law in divorce cases (the Rome III Regulation). Since then, it has been used for the European Patent with Unitary Effect, the European Public Prosecutor's Office (EPPO), and a proposed Financial Transaction Tax. Böttner (2021) analyses the constitutional framework of enhanced cooperation in detail, noting that the mechanism can only be used for specific projects, as a 'last resort' when EU-wide agreement is impossible, and cannot be used to advance the competences of the Union itself. Participating member states cannot exclude others from joining at a later stage, and the measures adopted must remain consistent with EU law as a whole. Patrin (2023) identifies a further layer of flexibility in EU secondary law: special regimes of closer cooperation that are modelled on but not fully reducible to enhanced cooperation. These include the Article 136(1) TFEU procedure for Eurozone-specific legislation, which allows euro area member states to adopt legal acts affecting only themselves through an accelerated procedure; the fast-track mechanism for enhanced cooperation in criminal law (Article 82 TFEU); and the Permanent Structured Cooperation (PESCO) in defence policy. Together, these mechanisms create a web of closer cooperation regimes that expand the repertoire of #legal_differentiation well beyond the headline cases of the Eurozone and Schengen. Tučić and Dragišić (2023) observe that while enhanced cooperation has partially fulfilled its treaty-defined role, its application creates particularities that may challenge the unity of the EU legal order, the prohibition of discrimination on the basis of citizenship, and legal certainty. Specifically, when enhanced cooperation produces different rules in different member states on matters of significant consequence — as in the case of the EPPO, which has jurisdiction over fraud against EU financial interests in participating states but not in others — citizens and businesses face an increasingly fragmented legal landscape. 4.3 Path Dependence and the Dynamics of Differentiation One of the most important findings in recent empirical research is that differentiation exhibits strong path dependence. Schimmelfennig and Winzen (2020) show, through analysis of EU treaty reforms and legislative differentiation, that the extent of pre-existing differentiation in a policy area is a significant predictor of further differentiation in subsequent treaty reforms, even when controlling for exogenous factors. Differentiation, in other words, breeds more differentiation. Early opt-outs create templates and precedents; they normalise the expectation that certain member states will stand apart; and they generate institutional infrastructures — separate Eurogroup meetings, Schengen Executive Committee formats, PESCO project groups — that make further differentiation organisationally routine. Malang and Schraff (2023) extend this finding in a politically important direction: opt-outs decrease integration support. Using panel matching estimates across data from 1994 to 2018 covering all voluntary primary law opt-outs, they find that after a differentiation is established, parties in the opt-out country become more Eurosceptic on average, and publics express lower preferences for future integration. This is a troubling finding for anyone who views differentiated integration as a transitional arrangement that will eventually be overcome: the evidence suggests, instead, that opt-outs reinforce themselves, embedding preferences for less integration rather than paving the way for eventual full participation. Zeitzmann (2022) asks directly whether exit strategies from differentiated integration exist — whether the ever more differentiated EU can reverse its trajectory. The analysis of mechanisms like the enhanced cooperation procedure, the passerelle clauses, and the flexibility clause of Article 352 TFEU suggests that reintegration is legally possible but politically costly. Instruments exist to move states back toward the common template, but the political will to use them depends on the same factors — domestic politics, sovereignty preferences, and economic capacity — that produced differentiation in the first place. 4.4 Differentiation Beyond the EU: External Dimensions Differentiated integration does not stop at the EU's formal membership boundary. The EU has developed an elaborate set of external differentiation arrangements — association agreements, the European Economic Area, Stabilisation and Association Agreements, and neighbourhood policy frameworks — that create a graduated system of membership-like statuses for non-EU countries. Schimmelfennig and Winzen (2020) describe this as a system of 'graded membership' in which countries are placed on a ladder of integration according to their governance quality and economic capacity, advancing when they improve and stalling when they do not. From a world-systems perspective, this external differentiation reproduces core-periphery structures at the continental scale. The EU's internal market norms, regulatory standards, and governance requirements are the product of negotiations dominated by core member states. When these standards are extended outward to associated or candidate countries through conditionality arrangements, peripheral and semi-peripheral countries face a choice between adopting rules they had no hand in making, or remaining outside frameworks that offer significant economic benefits (Czubocha, 2023). This is not a neutral process: it is an extension of EU institutional power beyond its borders, dressed in the language of shared values and mutual benefit. 5. Findings The synthesis of the legal analysis and theoretical frameworks above produces several significant findings, each with implications for how we understand the European project. Finding 1: Differentiation is structural, not exceptional. The dominant narrative in EU political discourse often treats #opt-outs and derogations as unfortunate exceptions to the normal logic of integration. The empirical record does not support this framing. Schimmelfennig and Winzen (2020) show that differentiation has been a consistent and growing feature of EU law, increasing in both treaty law and secondary legislation over the entire history of the Union. Telle, Brunazzo, and Doidge (2021) confirm that from Rome (1958) to Lisbon (2009), all founding treaties have contained exceptions from common provisions, and that the Lisbon Treaty was itself a milestone for differentiated integration. Differentiation is not a bug in the EU system; it is a feature, and arguably a necessary one for a Union whose membership has grown from six to twenty-seven states with very different economic profiles, sovereignty preferences, and political cultures. Finding 2: Most differentiation is multi-speed, not permanently exclusionary. Despite the attention paid to dramatic cases like the UK's former opt-outs or Denmark's euro derogation, the majority of differentiated arrangements in EU history have been temporary. Instrumental differentiations granted to new member states during enlargements typically expire within a few years as those states build the capacity to comply with common rules. The EU's overall trajectory has thus been broadly isomorphic — moving toward greater uniformity over time — even as specific sub-groups maintain differentiated positions in specific domains. Schimmelfennig and Winzen's data show no evidence of a trend toward an 'ever looser union' when differentiation is measured relative to the growth in EU authority and membership. Finding 3: Constitutional differentiation creates durable multi-tier structures in core state powers. The exception to the multi-speed finding concerns areas of #core_state_powers: monetary policy, security and defence, border control, criminal justice. In these domains, constitutional differentiations — reflecting genuine preference divergence among wealthy, sovereignty-conscious states — have shown strong persistence and path dependence. The Eurozone crisis deepened this divide: euro area member states adopted far-reaching centralising reforms and financial commitments that non-euro area members refused or were excluded from, and the legal gap between insiders and outsiders in macroeconomic governance has grown over time (Schimmelfennig and Winzen, 2020). Markakis (2020) argues that this inner-outer core distinction is very difficult to disentangle in practice, since economic governance, fiscal policy, banking regulation, and internal market rules are deeply interdependent. Finding 4: Opt-outs can entrench Euroscepticism rather than contain it. The political science literature raises a sobering challenge to the strategic logic of differentiated integration. Its proponents sometimes argue that opt-outs are a safety valve: by allowing nationally-minded states to stay outside particular integration initiatives, the Union preserves consent and avoids exit. Malang and Schraff (2023) complicate this argument by showing that opt-outs appear to reinforce rather than reduce Euroscepticism over time — parties and publics in states with opt-outs become more, not less, resistant to future integration. De Blok and De Vries (2022) add a further nuance: support for differentiation in the form of multiple speeds is higher among pro-EU citizens who see it as a way to overcome integration gridlock, while support for opt-outs is higher among Eurosceptic citizens who see it as a way to limit EU authority. Differentiation, in short, means different things to different political actors, and cannot easily be counted on to build broad-based support for the European project. Finding 5: The legal architecture of enhanced cooperation is underutilised but has significant potential. Despite its formal flexibility, enhanced cooperation has been used only a handful of times since its introduction in 1997. Böttner (2021) argues that the mechanism's constitutional framework is adequate for significant integration projects, but that treaty reform could increase its functionality — particularly around the right of withdrawal and the safeguarding measures that protect non-participating member states. De Witte (2022) surveys the full range of differentiation options available under current treaty law and concludes that many of the reforms frequently discussed — in areas like economic governance, migration, tax harmonisation, and defence — do not require treaty revision and can be achieved through existing differentiation mechanisms, including enhanced cooperation and international agreements among member states. This finding has significant practical implications: the instruments for further differentiated integration already exist; the limiting factor is political will, not legal architecture. 6. Conclusion Differentiated integration is, by now, one of the most important structural features of the European Union. It is not a passing phase or a political compromise destined to dissolve as member states gradually converge. It is, as the evidence reviewed here consistently shows, a permanent feature of a Union that has chosen breadth over depth on a number of its most sensitive governance challenges, and that has found in legal flexibility the instrument to hold its diverse membership together. The theoretical frameworks applied in this article help explain why. Bourdieu's field theory reveals that the EU governance space is not an arena of equal sovereigns but a structured field in which dominant states — primarily Germany and France — have disproportionate influence over the rules of #integration. When powerful states negotiate opt-outs, they are exercising field dominance, not simply asserting national interests in a neutral bargaining space. When smaller or peripheral states seek derogations, they are often doing so from a position of weaker capital — economic, institutional, and political — that limits their ability to shape the terms of the debate. The concept of symbolic violence is useful here: the language of 'derogations' and 'exceptions' naturalises a particular integration template as the neutral norm, obscuring the power dynamics that produced it. World-systems theory draws attention to the spatial patterning of differentiation within the EU. Constitutional opt-outs from core state powers have been exercised predominantly by wealthy, core or near-core states. Instrumental differentiations — phased compliance with common rules — have been predominantly experienced by peripheral and semi-peripheral states. This mapping is not coincidental: it reflects the structural asymmetries in governance capacity, economic development, and political leverage that world-systems theory predicts. The #Eurozone crisis made these asymmetries visible in acute form, as peripheral member states were subjected to austerity conditionality designed largely by core state creditors, deepening the integration divide between euro area insiders and outsiders. Institutional isomorphism explains why, despite this differentiation, the EU has retained a broadly common legal framework and continued to expand the scope of common rules. The coercive, normative, and mimetic pressures toward institutional convergence remain powerful. Accession conditionality is one of the strongest isomorphic mechanisms in the world, having transformed the legal systems of twelve new member states in the two decades since enlargement in 2004 and 2007. The question, as Malang and Schraff (2023) warn, is whether path-dependent differentiation in core state powers will prove stronger than the isomorphic pull in the long run. The legal instruments reviewed in this article — treaty opt-outs, protocols, enhanced cooperation, PESCO, Eurozone-specific legislation — are sophisticated and in many respects effective tools for managing integration in a diverse Union. They have allowed the EU to deepen in areas like monetary union and border-free travel without requiring unanimous participation. They have permitted enlargement to proceed without demanding immediate compliance with all common rules. They have given politically sensitive states an exit from particular integration initiatives that might otherwise have blocked progress altogether. But they carry costs. They create legal complexity, institutional fragmentation, and differential rights for citizens of participating and non-participating states. They may reinforce rather than dissolve the Eurosceptic preferences they are meant to accommodate. And in areas of core state powers, they risk producing durable divides between an inner core of deeply integrated states and an outer tier of states that are formally members but substantively excluded from the most consequential governance decisions. The future of a #multi-speed_Europe will depend less on the legal architecture — which, as De Witte (2022) shows, is already sufficiently flexible — and more on whether political leaders can build the sustained coalitions necessary to advance integration in areas where it matters most, while managing the diversity of a twenty-seven-member Union without deepening its structural inequalities. That is, ultimately, a political challenge that no treaty protocol can resolve alone. This article offers an initial, conceptually grounded treatment of a large and rapidly evolving field; further empirical and comparative research — particularly on how citizens in differentiated member states understand and evaluate their opt-out status — would add significant depth to the picture.

This article evaluates the complex legal frameworks governing how the #European_Union (EU) operates as a unified global actor in international treaty negotiations, the #Common_Commercial_Policy (CCP), and international diplomacy. Moving beyond traditional doctrinal analysis, this study integrates critical social and economic theories—specifically Pierre Bourdieu’s concepts of #jurisdictional_capital, Immanuel Wallerstein’s #world_systems_theory, and DiMaggio and Powell’s #institutional_isomorphism. Through a qualitative analysis of EU constitutional instruments, including the Treaty on European Union (TEU) and the Treaty on the Functioning of the European Union (TFEU), alongside recent jurisprudence from the European Court of Justice (ECJ), we map the structural mechanics of EU #external_competence. Our findings show that the EU projects its global legal power through a process of coercive and mimetic isomorphism, positioning itself as a primary regulator in the global core while pulling peripheral and semi-peripheral nations into legal alignment. The paper concludes by presenting a comprehensive taxonomy of EU treaty-making power and the structural tensions inherent to mixed agreements. Introduction The #European_Union operates as a highly unique entity within the landscape of public #international_law. It is neither a traditional nation-state nor merely a loose intergovernmental organization. Instead, it functions as a supranational legal order equipped with an independent institutional framework capable of concluding treaties, enforcing trade policies, and projecting regulatory standards worldwide. The constitutional architecture that enables this unified action is known as EU External Relations Law. This framework governs how the Union interacts with non-member states (third countries) and international bodies, defining the scope and limits of its international identity. Historically, the ability of the EU to act as a cohesive global power has been complicated by the competing sovereign interests of its Member States. The transition from a fragmented economic community to a consolidated global actor required a sophisticated constitutional equilibrium. This equilibrium was fundamentally restructured by the Treaty of Lisbon, which granted the Union explicit #legal_personality and unified its external action mechanisms under a singular constitutional framework. Understanding how the EU projects legal power requires analyzing both its explicit treaty provisions and the implicit jurisprudential doctrines developed by the European Court of Justice (ECJ). The legal reality of EU external action is deeply connected to global economic and political hierarchies. To explore these dynamics fully, this article examines EU External Relations Law through three distinct theoretical lenses: Bourdieusian Sociology: Analyzing how the EU leverages its accumulated #legal_capital and structural status within the global jurisdictional field. World-Systems Theory: Examining how the EU uses its trade frameworks to maintain its position as a global core economy while shaping the legal systems of peripheral and semi-peripheral nations. Institutional Isomorphism: Investigating how the Union pressures external jurisdictions and international organizations to mimic its internal regulatory architectures. This study systematically maps the legal parameters dictating how the EU negotiates international treaties, manages its Common Commercial Policy (CCP), and enforces external compliance. By doing so, it provides a comprehensive overview of the Union's operational capacity as a unified actor on the global stage. Background and Theoretical Framework The Legal Evolution of EU External Competence The foundational architecture of EU external relations law rests on the principle of conferred powers (Article 5 TEU), which dictates that the Union can only act within the boundaries of the competences allocated to it by the Member States. However, the nature of global governance requires an adaptable approach to international law-making. The ECJ addressed this early on through the development of the doctrine of implied external competence. In its landmark ERTA judgment, the Court established that the Union’s power to enter into international agreements does not rely solely on explicit treaty grants but can be implied from its internal legislation. If the EU adopts internal rules to achieve a specific treaty objective, it simultaneously acquires the exclusive external competence necessary to negotiate corresponding international commitments to protect those rules. The Treaty of Lisbon codified and structured these developments. It explicitly divided EU external competences into three operational categories: Exclusive Competence (Article 3 TFEU): Areas where the Union alone can legislate and conclude international agreements, including the Common Commercial Policy, customs unions, and the conservation of marine biological resources. Shared Competence (Article 4 TFEU): Domains where both the Union and the Member States can act. However, Member States can only exercise their competence to the extent that the Union has not already exercised its own. Coordinating/Supplementary Competence (Article 6 TFEU): Fields where the EU can support, coordinate, or supplement the actions of Member States without replacing their national authority (e.g., humanitarian aid and development cooperation). Integration of Socio-Legal Theories 1. Bourdieusian Field Theory and Jurisdictional Capital Pierre Bourdieu’s sociological framework—centered on fields, habitus, and capital—offers valuable insights when applied to international legal systems. The global arena of treaty-making and regulatory governance can be understood as a highly competitive jurisdictional field. Within this field, international actors compete to establish their preferred rules as the authoritative global standard. The EU enters this field with an exceptional accumulation of legal capital and institutional prestige. This structural capital allows the Union to act as a primary "norm exporter." By treating international law-making as an elite administrative process, the EU relies on its complex internal bureaucracy to project a distinct legal identity. This approach often compels third countries to adapt to EU legal standards simply to participate effectively within the global legal field. 2. World-Systems Theory and the Common Commercial Policy Immanuel Wallerstein’s #world_systems_theory divides the global macro-economy into three structural zones: the core, the semi-periphery, and the periphery. The core is characterized by high-capital, high-technology production and dominant institutional structures, while the periphery provides raw materials, low-wage labor, and subordinate markets. The EU functions as an archetypal institutional core power. Its Common Commercial Policy (CCP), governed by Article 207 TFEU, serves as a primary legal instrument for managing relations with peripheral and semi-peripheral zones. Through preferential trade agreements, Economic Partnership Agreements (EPAs), and conditional market-access frameworks, the EU embeds its internal labor, environmental, and administrative standards directly into the domestic legal codes of its trading partners. This dynamic uses commercial access to expand the Union’s regulatory reach, reinforcing core-periphery dependencies through structured legal mechanisms. 3. Institutional Isomorphism in Global Governance DiMaggio and Powell’s theory of institutional isomorphism explains why organizations and legal systems tend to become structurally similar over time. This process occurs through three primary mechanisms: coercive, mimetic, and normative isomorphism. All three are highly visible in the projection of EU external legal power: Coercive Isomorphism: Driven by direct political and economic pressures. For instance, the EU routinely includes strict "essential elements" clauses regarding human rights, data protection, and anti-corruption measures in its international trade agreements. Third states must adopt these legal frameworks as a mandatory condition for market access. Mimetic Isomorphism: Occurs when external jurisdictions voluntarily copy the EU's legal structures to resolve internal administrative uncertainties or to achieve international legitimacy. A prime example is the global adoption of data privacy regimes modeled directly on the EU’s General Data Protection Regulation (GDPR)—a phenomenon often described as the "Brussels Effect." Normative Isomorphism: Propagated through professional networks, academic exchanges, and shared administrative cultures. The export of EU legal education and regulatory training models helps establish a standardized worldview among global legal professionals, making compliance with EU-style frameworks the expected norm. Method This study utilizes a qualitative, doctrinal, and socio-legal methodology to evaluate the operational structure of EU external relations law. Given the complex nature of supranational constitutional frameworks, our analytical approach combines rigorous text-based examination of primary legal sources with a macro-theoretical analysis of global regulatory power. Data Corpus and Selection Criteria The primary legal data corpus compiled for this analysis consists of three interconnected elements: Constitutional Texts: The consolidated versions of the Treaty on European Union (TEU) and the Treaty on the Functioning of the European Union (TFEU). International Treaty Agreements: A selected sample of comprehensive trade and strategic partnership agreements negotiated by the EU over the last two decades (e.g., CETA with Canada, EU-Singapore FTA, and various regional Economic Partnership Agreements). Jurisprudence: Key judgments from the European Court of Justice (ECJ) that clarify the boundaries of external competence, including the foundational ERTA case, Opinion 1/94 (WTO), Opinion 2/15 (EU-Singapore FTA), and recent rulings up to 2026 regarding the enforcement of internal standards through external actions. Analytical Framework The analytical pipeline follows a multi-stage approach designed to connect formal legal rules with their broader structural impacts: [Primary Data Collection: Treaties & ECJ Case Law] │ ▼ [Doctrinal Isolation of External Competences (Art. 3, 4, 207 TFEU)] │ ▼ [Thematic Theoretical Mapping via Bourdieusian, World-Systems, & Isomorphic Lenses] │ ▼ [Synthesis of Regulatory Vectors (The Brussels Effect & Treaty Taxonomy)] First, we isolate the specific treaty provisions governing the negotiation and conclusion of international treaties (Articles 216–218 TFEU) and the administration of the CCP (Articles 206–207 TFEU). Second, we trace how these provisions are applied in practice, paying close attention to the use of "mixed agreements"—treaties that require ratification by both the EU and each individual Member State. Finally, we evaluate the gathered legal data using our three theoretical frameworks, mapping how formal treaty mechanics translate into structural global power. Analysis: The Mechanics of EU Treaty-Making and Commercial Policy The Procedural Architecture of Article 218 TFEU Article 218 TFEU serves as the foundational procedural roadmap for how the EU negotiates, signs, and concludes international agreements. This provision establishes a carefully balanced distribution of power between the European Commission, the Council of the European Union, and the European Parliament, ensuring that both supranational interests and Member State concerns are represented. The treaty-making process follows a structured sequence of institutional actions: [1. Commission Initiation & Recommendation] ──> [2. Council Authorization & Mandate] │ ▼ [4. Council Conclusion (with EP Consent)] <── [3. Commission Negotiation Phase] Initiation and Recommendation: The process begins with the European Commission (or the High Representative of the Union for Foreign Affairs and Security Policy for matters relating to the Common Foreign and Security Policy) submitting a formal recommendation to the Council to open negotiations. Authorization and Mandate: The Council evaluates the recommendation and adopts a decision authorizing the opening of negotiations. Crucially, the Council issues specific negotiating directives. These directives act as a legal mandate that bounds the Commission's bargaining parameters during talks with third states. The Negotiation Phase: The Commission serves as the Union’s sole negotiator, managing direct discussions with the external party. Throughout this phase, the Commission must regularly report to a special committee appointed by the Council (the "Article 218 Special Committee") to ensure the negotiations align with the interests of the Member States. Consent and Conclusion: Once the text is finalized, the Council adopts a decision authorizing the signing of the agreement. However, before the Council can formally conclude the treaty, it must obtain the consent of the European Parliament in most major policy areas (including trade, association, and agreements with significant budgetary implications). This requirement ensures democratic oversight for the Union's international commitments. The Common Commercial Policy (CCP) and Autonomous Measures The Common Commercial Policy, outlined in Articles 206 and 207 TFEU, is one of the EU’s most potent instruments for projecting global influence. As an exclusive competence, the CCP allows the Union to act as a single, unified trade bloc. This concentration of economic authority grants the EU considerable bargaining leverage when dealing with individual foreign nations. The scope of the CCP expanded significantly under the Treaty of Lisbon to encompass not just traditional trade in goods and customs tariffs, but also: Trade in services. Commercial aspects of intellectual property (TRIPS). Foreign direct investment (FDI). Beyond negotiating bilateral and multilateral trade agreements, the EU frequently deploys autonomous regulatory measures within its internal market that carry significant external consequences. These instruments are designed to enforce compliance with core EU standards beyond its geographical borders. Notable examples include the Foreign Subsidies Regulation (FSR) and the Corporate Sustainability Due Diligence Directive (CSDDD). By making access to its massive consumer market conditional on compliance with these internal environmental, labor, and financial transparency rules, the EU effectively reshapes the operational environments of foreign companies. This strategic leverage allows the Union to export its legal standards globally without needing to secure formal bilateral treaties first. Mixed Agreements and the Challenge of National Ratification While the EU holds extensive exclusive powers, many modern comprehensive agreements cross into areas of shared competence. When an international treaty covers both exclusive EU matters (such as tariff reductions) and shared or national matters (such as investor-state dispute settlement or certain political cooperation clauses), it must be concluded as a mixed agreement. Mixed agreements create significant procedural complexity. They require approval not only from the EU institutions via the Article 218 TFEU process, but also individual ratification by all Member States in accordance with their respective constitutional requirements. This process can involve over thirty separate national and regional parliaments across the continent. The legal risks of this approach were clearly illustrated during the ratification of the EU-Canada Comprehensive Economic and Trade Agreement (CETA). A regional parliament in Belgium successfully delayed the signature of the entire treaty by withholding its domestic consent, highlighting how a single sub-national legislature can stall the external action of the world’s largest trading bloc. To mitigate these ratification bottlenecks, the EU has increasingly adopted a strategy of bifurcation. As seen in the split of the EU-Singapore and EU-Vietnam agreements, the Commission now separates treaties into two distinct parts: a standalone trade agreement containing exclusively EU-level competences (which can be concluded quickly via the Council and European Parliament) and a separate investment protection agreement containing shared competences (which proceeds along the slower path of national ratification). Findings: The Structural Vectors of EU Legal Power Our analysis reveals that the projection of EU external legal power is not a neutral, purely administrative exercise. Instead, it operates as a structured mechanism that establishes global regulatory hierarchies. By examining the intersection of treaty mechanics and socio-legal theory, we identify three primary structural vectors through which the EU exercises its global influence. 1. The Brussels Effect as Mimetic and Coercive Isomorphism The "Brussels Effect" describes the EU's unique ability to set unilateral regulatory standards that foreign corporations and states adopt globally. Our findings show that this phenomenon does not rely on traditional military or geopolitical pressure; rather, it operates through a combination of coercive and mimetic isomorphism. ┌──> Coercive Vector: Market Access Conditionality │ (e.g., GDPR / CSDDD Compliance Mandates) EU Legal Capital ───┤ │ └──> Mimetic Vector: Voluntary Standard Alignment (e.g., Third-countries copying EU digital/eco laws) The size and economic value of the single market make compliance with EU standards a commercial necessity for global business operations. Rather than maintaining multiple distinct production chains, multinational corporations often find it more cost-effective to standardize their global operations around the EU's strict criteria. This corporate adaptation drives state-level legal convergence. Foreign governments frequently mirror EU legislation within their domestic legal systems to ensure their domestic industries maintain seamless access to European consumers. Through this process, the EU exports its regulatory architecture, establishing its internal policy preferences as baseline global standards. 2. Core-Periphery Legal Conditioning via Commercial Policy Viewed through world-systems theory, the EU’s external agreements function as sophisticated legal frameworks designed to secure the economic stability of the global core. By embedding comprehensive regulatory demands within trade concessions, the EU systematically reshapes the legal environments of peripheral and semi-peripheral nations. ┌────────────────────────────────────────────────────────┐ │ EU CORE │ │ Accumulated Jurisdictional Capital │ └───────────────────────────┬────────────────────────────┘ │ Trade Access │ Regulatory Demands & Concessions │ & Legal Conditioning ▼ ┌────────────────────────────────────────────────────────┐ │ PERIPHERY / SEMI-PERIPHERY │ │ Adopts Coercive & Mimetic Legal Shifts │ └────────────────────────────────────────────────────────┘ Our analysis of EU Economic Partnership Agreements (EPAs) shows that peripheral signees are routinely required to reform their domestic laws concerning competition, intellectual property protection, public procurement, and environmental management to match EU standards. While these reforms are framed as modernization initiatives, they effectively align the domestic legal architectures of developing economies with the market preferences of Western European industries. This ensures that peripheral markets remain accessible and legally predictable for core-based capital investment. 3. Competence Creep and Jurisdictional Consolidation The third major vector of EU legal power is internal and jurisprudential. The ECJ has consistently protected and expanded the Union's external reach by applying the principle of systemic effectiveness (effet utile). Through its interpretive jurisprudence, the Court has routinely checked Member States' attempts to assert independent international identities in areas that could affect internal EU policies. This ongoing consolidation of external competence has transformed the EU into a formidable, single-voice actor in international forums like the World Trade Organization (WTO) and various UN bodies. By restricting Member States from undertaking independent international obligations that might interfere with common European rules, the ECJ has built a centralized legal fortress. This architecture ensures that when the EU enters international negotiations, it brings the combined weight of its entire internal market, maximizing its ability to project power globally. Conclusion EU External Relations Law provides a sophisticated constitutional framework that successfully projects the Union's legal and economic power worldwide. Through the procedural mechanics of Articles 207 and 218 TFEU, supported by the external competence doctrines developed by the ECJ, the EU has established itself as a primary regulator within the global landscape. By integrating sociological and economic frameworks into our legal analysis, we find that the EU’s treaty-making and commercial actions extend far beyond simple economic cooperation. The Union actively leverages its accumulated legal capital to reshape foreign jurisdictions. Through coercive and mimetic isomorphism, it frequently requires both corporate entities and sovereign states to align with its internal regulatory models. Furthermore, from a world-systems perspective, the EU’s trade policies serve to protect its position as an economic core power by conditioning market access on structural legal reforms within peripheral and semi-peripheral nations. However, this method of projecting power faces ongoing internal challenges. The procedural complexities of mixed agreements and the requirement for unanimous national ratifications reveal a persistent tension between supranational ambitions and national sovereignty. As the EU continues to address a changing global environment, its ability to maintain internal institutional cohesion will determine its long-term effectiveness as a unified global actor. Key Legal Framework Summary Treaty Provision / Doctrine Constitutional Classification Core Operational Mechanism Socio-Legal Implications Article 207 TFEU (CCP) Exclusive Competence Gives the EU sole authority over global tariffs, services, intellectual property rights, and foreign investments. Acts as a primary mechanism for core-periphery legal conditioning. Article 218 TFEU Procedural Framework Establishes the institutional steps for treaty negotiations, requiring Council mandates and Parliamentary consent. Formalizes institutional interactions within the elite global legal field. ERTA Doctrine (ECJ) Implied Competence Dictates that external negotiation powers become exclusive to the EU whenever internal rules have been established. Drives competence creep and the central accumulation of legal capital. Mixed Agreements Shared Competence Requires parallel ratification by both European institutions and all individual Member State parliaments. Creates institutional bottlenecks that test internal cohesion.

This article traces the long and contested journey of #fundamental_rights protection within the #EU_legal_order, from the economic origins of the European Communities to the binding legal status of the #Charter_of_Fundamental_Rights following the #Treaty_of_Lisbon in 2009. Drawing on the foundational analysis of Douglas-Scott (2011), as well as a range of more recent scholarship, the article argues that this evolution was neither linear nor inevitable. Rather, it was shaped by structural pressures, judicial activism, and the progressive constitutionalisation of a supranational legal system that initially had no intention of becoming a #human_rights organisation. The article applies three sociological and theoretical frameworks — Bourdieu's concept of the #legal_field, #world_systems_theory, and #institutional_isomorphism — to explain why and how the EU developed its fundamental rights architecture over several decades. It further examines the persistent tension between #supranational_standards and #national_constitutional_identity, particularly as expressed in the responses of national constitutional courts to the Charter. The article finds that while the Charter represents a landmark achievement in #multilevel_rights_protection, its application remains fragmented and contested, caught between the ambitions of the #Court_of_Justice_of_the_EU (CJEU) and the resistance of member state courts defending their constitutional prerogatives. The article concludes that the future of fundamental rights in the EU depends on genuine #judicial_dialogue rather than hierarchical imposition. Keywords: #Charter_of_Fundamental_Rights, #EU_fundamental_rights, #CJEU, #national_constitutional_courts, #Treaty_of_Lisbon, #institutional_isomorphism, #Bourdieu_legal_field, #judicial_dialogue, #constitutional_identity, #human_rights_protection, #EU_legal_order, #supranational_law, #multilevel_governance 1. Introduction When the founders of the European Communities signed the Treaty of Rome in 1957, the idea that the new organisation would one day possess a legally binding #bill_of_rights would have seemed extraordinary. The project was, at its core, an economic one — designed to create a common market, reduce trade barriers, and bind the war-torn nations of Western Europe together through commerce. The language of #fundamental_rights, of dignity, liberty, and equality, belonged to another architecture entirely: to national constitutions written in the shadow of fascism, and to international instruments like the #European_Convention_on_Human_Rights (ECHR) adopted under the Council of Europe. Yet, over the course of roughly six decades, the EU did become a human rights actor. It developed a #fundamental_rights jurisprudence through the case law of the Court of Justice. It proclaimed a Charter of Fundamental Rights in 2000. And with the entry into force of the Treaty of Lisbon in December 2009, that Charter became part of primary EU law, carrying the same legal weight as the founding Treaties. This transformation raises important questions that this article sets out to address: How did this happen? What forces — legal, political, social, and structural — drove the EU towards embracing #human_rights as a core part of its identity? And what problems has this transformation created, particularly in relation to the courts of EU member states, which must now navigate between their national constitutions and the demands of an increasingly assertive #supranational_rights_regime? This article is structured as a doctrinal and theoretical analysis. It draws on the seminal work of Douglas-Scott (2011), who provided one of the most searching critiques of the EU's fundamental rights landscape at the moment of the Charter's entry into force, noting both its promise and its deeply ambivalent relationship with national legal systems. The article builds on this foundation using more recent scholarship to assess how the tensions Douglas-Scott identified have developed in the years since. Crucially, the article employs three theoretical lenses — Pierre Bourdieu's concept of the #legal_field, #world_systems_theory as developed in the tradition of Wallerstein, and the concept of #institutional_isomorphism from organisational sociology (DiMaggio and Powell) — to provide a richer sociological explanation of the EU's rights evolution. These frameworks reveal that the development of fundamental rights protection in the EU was not simply a story of enlightened legal progress, but also one of competition, power, and the structural pressures that shape legal institutions in an interconnected world. 2. Background and Theoretical Framework 2.1 The Economic Origins and the Silence on Rights The foundational treaties of the European Communities contained no explicit catalogue of #fundamental_rights. This was not an oversight. The drafters of the Treaty of Rome were aware of the ECHR and the constitutional bills of rights of member states. The decision to focus exclusively on economic integration was deliberate: rights protection was seen as belonging to national constitutional orders and to the Council of Europe, not to a market-building institution. As Marcisz-Dynia and Milczanowski (2021) document in their analysis of EU primary legislation, the founding treaties were structured around the principles of economic freedoms — the free movement of goods, services, capital, and persons — with no comparable protection for the civil and political rights of individuals. This initial silence created what scholars have called a legitimacy gap. As the Communities expanded their competences into areas touching the daily lives of citizens — employment, social policy, immigration — the absence of a #rights_framework became increasingly problematic. The #Court_of_Justice could not ignore this indefinitely. The pressure came, initially, from national constitutional courts. The German Federal Constitutional Court, in its Solange I judgment of 1974, famously threatened to review Community acts against German fundamental rights guarantees as long as ('solange') the Community lacked an equivalent level of rights protection. This represented a direct challenge to the supremacy of Community law, and it forced the Court of Justice to respond. 2.2 Bourdieu and the Legal Field Pierre Bourdieu's concept of the #legal_field offers a powerful tool for understanding the dynamics that produced the EU's rights evolution. For Bourdieu, a field is a structured social space in which actors compete for capital — resources, authority, legitimacy — according to rules that are internal to that field. The legal field is one in which jurists, judges, and legal scholars compete to define what the law is and what it should be. Capital in the legal field includes doctrinal authority, judicial precedent, and the symbolic power to define legal categories. Applying this framework to the EU, one can see that the development of fundamental rights as general principles of EU law in the 1970s was partly a product of competition within the #EU_legal_field. The Court of Justice needed to defend the supremacy and autonomy of Community law against the resistance of powerful national constitutional courts. Developing its own #fundamental_rights doctrine allowed the Court to claim legitimate authority over a domain that those national courts had threatened to colonise. The proclamation of the Charter in 2000 and its subsequent elevation to binding status in 2009 can be read as a further consolidation of the EU's position in the broader European #legal_field — a claim to be not merely a market regulator but a genuine constitutional order with its own bill of rights. This Bourdieusian reading prevents a naive or purely teleological account of EU rights development. Progress was not inevitable; it was the outcome of strategic competition between institutional actors, each seeking to defend and expand their authority within overlapping legal fields. 2.3 World-Systems Theory and the EU as Legal Hegemon #World_systems_theory, associated primarily with Immanuel Wallerstein, divides the international order into core, semi-periphery, and periphery. Core states and institutions set the rules that others are expected to follow; peripheral actors adapt or resist. Applied to the EU's #fundamental_rights framework, this perspective is illuminating. The EU, as a core institution, has used its legal order to export standards. Lazowski (2020) documents how the EU Charter has influenced domestic jurisprudence even in countries that are not EU members — a phenomenon he calls the exportability of EU law — demonstrating the structural power of the EU as a norm-setter in the European legal space. This dynamic also operates within the Union itself. When smaller or newer member states join the EU, they do not negotiate the terms of the #fundamental_rights acquis on equal terms. They are expected to adopt and implement the EU's rights framework as a condition of membership and continued participation in the Union. The pressure placed on countries like Hungary and Poland in recent years regarding the rule of law and judicial independence illustrates how the EU's #rights_architecture functions partly as an instrument of structural power, enforcing core standards on members who may not always share them. 2.4 Institutional Isomorphism The concept of #institutional_isomorphism, developed by DiMaggio and Powell (1983), describes the process by which organisations within the same field come to resemble one another over time. Three mechanisms drive this convergence: coercive isomorphism (pressure from external actors with authority), mimetic isomorphism (imitation of successful models under conditions of uncertainty), and normative isomorphism (the spread of professional norms through education and professional networks). All three mechanisms are visible in the evolution of EU fundamental rights. Coercive isomorphism is evident in the pressure exerted on member states to align their legal systems with EU standards, including Charter requirements, as a condition of continued EU membership and access to EU funds. Mimetic isomorphism appears in the way that national constitutional courts in Austria, Italy, and Germany have, over time, incorporated the Charter as a reference point for their own constitutional review — not because they are required to do so in all cases, but because the Charter represents a model of best practice in rights protection that it is rational to imitate (Rauchegger, 2020). Normative isomorphism operates through the legal profession itself: EU law is now a central part of legal education across Europe, and a generation of judges and lawyers has been trained to think in terms of the Charter and the jurisprudence of the CJEU. Together, these processes help explain why the EU's fundamental rights framework has spread and deepened even in the face of political resistance, producing a degree of legal convergence that no single Treaty amendment could have achieved by itself. 3. Method This article employs a qualitative, interpretive approach combining doctrinal legal analysis with critical theoretical engagement. The primary materials analysed include the founding Treaties of the European Communities and Union, the Treaty of Lisbon, the Charter of Fundamental Rights, and key judgments of the Court of Justice. These are read alongside secondary scholarship in EU constitutional law, sociology of law, and political theory. The theoretical frameworks of Bourdieu, world-systems theory, and institutional isomorphism are applied not as rigid analytical templates but as interpretive lenses that illuminate different dimensions of a complex historical and legal phenomenon. The article does not aim to provide a comprehensive case law survey; rather, it traces the structural conditions and turning points that shaped the development of #fundamental_rights in the EU, with attention to the ongoing tensions between #supranational_authority and #national_constitutional_autonomy. Sourced materials were drawn from peer-reviewed journals, scholarly books, and working papers published between 2020 and 2026, supplemented by the foundational analysis of Douglas-Scott (2011) as the primary reference point named in the research prompt. Where the article draws on this earlier work, it notes where subsequent scholarship has confirmed, qualified, or extended the original analysis. 4. Analysis 4.1 The Court of Justice and the Development of General Principles The first major phase in the development of #EU_fundamental_rights took place through judicial innovation rather than Treaty revision. Beginning with the Stauder case (1969) and continuing through Internationale Handelsgesellschaft (1970) and Nold (1974), the #Court_of_Justice progressively established that fundamental rights formed part of the general principles of Community law. The source of these rights was identified as the common constitutional traditions of member states and international human rights treaties — prominently the ECHR — to which member states were parties. This was a remarkable exercise of judicial creativity. In the absence of any Treaty mandate, the Court constructed a fundamental rights doctrine to serve the dual purpose of protecting individuals and, crucially, defending the autonomy of Community law against the claims of national constitutional courts. As Lebedeva (2023) observes in a historical survey of the Court of Justice's human rights jurisprudence, the Court's approach in the 1970s established the key structural features of #EU_fundamental_rights that would persist for decades: rights derived from common constitutional traditions, interpreted by the Court itself, and capable of overriding conflicting Community acts. This judge-made rights framework had real limitations, however. It was uncertain in scope, difficult to invoke by individuals without first triggering the preliminary reference procedure, and entirely dependent on the Court's willingness to recognise particular rights as general principles. There was no catalogue of rights that citizens could point to; no clear hierarchy between competing rights; and no effective remedy at the national level in many circumstances (Vrabie, 2020). The structural limitations of a judge-made system without a codified framework would eventually necessitate the move towards a written charter. 4.2 The Charter of Fundamental Rights: From Proclamation to Bindingness The proclamation of the #Charter_of_Fundamental_Rights in Nice in December 2000 was, at first, a political act without legal force. The Charter brought together in one document the civil, political, economic, social, and 'third generation' rights that the EU recognised as part of its fundamental rights heritage. It was a visually impressive document — comprehensive, clearly structured, and symbolically powerful — but it had the legal status of a political declaration rather than a binding instrument. For nearly a decade, the Charter occupied an ambiguous position. It was not legally binding, yet it was not entirely without effect. The Court of Justice cited it as a source of inspiration. Advocates General drew on it in their opinions. National courts noted its existence. The Charter was becoming part of the normative vocabulary of European law even before it formally entered that law. This pre-binding influence is itself a phenomenon amenable to analysis through the lens of #institutional_isomorphism: actors in the legal field began behaving as if the Charter were authoritative before it officially was, because doing so aligned with the professional norms and expectations of the emerging EU #legal_community. The transformation came with the #Treaty_of_Lisbon. Article 6(1) TEU, as amended by Lisbon, declared that the Charter 'shall have the same legal value as the Treaties.' From 1 December 2009, the Charter became primary EU law — not simply a helpful reference but a legally enforceable yardstick for reviewing the compatibility of EU acts and, crucially, member state action taken within the scope of EU law. As de Witte (2025) notes, this elevation of the Charter completed a decades-long process of constructing a multilevel human rights architecture in Europe that now involves the interaction of three distinct systems: national constitutional rights, the EU Charter, and the ECHR. The scope of the Charter's application to member states was defined by Article 51 CFR, which provides that the Charter applies to member states 'only when they are implementing Union law.' This limitation was intended to respect the autonomy of national constitutional systems. However, the CJEU has interpreted the notion of 'implementation' broadly, generating significant controversy. Cases like Åkerberg Fransson (2013), in which the Court applied the Charter in a case involving tax evasion penalties under a system partly regulated by EU law, extended the Charter's reach considerably beyond what many national governments had anticipated. As Tubić (2024) documents in his analysis of the current status of human rights in the EU legal system, this expansive jurisprudence has kept the boundaries of the Charter's application to member states permanently contested. 4.3 Tensions with National Constitutional Courts The binding Charter has generated substantial friction with national constitutional courts, and this tension represents the most significant unresolved problem in the EU's #fundamental_rights architecture today. Three dimensions of this tension deserve particular attention. The first is the question of who has the final word on the meaning of fundamental rights when EU law and national constitutional law diverge. The CJEU operates on the assumption that EU law, including the Charter, has primacy over national law, including national constitutions. National constitutional courts, by contrast, maintain that their constitutions establish the ultimate framework of legal authority within their states, and that EU law derives its force from the national constitutional act of ratification. This conflict of ultimate authority is not merely theoretical. In its Melloni judgment (2013), the CJEU ruled that member states cannot apply a higher national standard of fundamental rights protection where doing so would compromise the uniformity and primacy of EU law. This reasoning, as Lebedeva (2023) points out, was deeply controversial and was received with unease by constitutional courts that had long regarded themselves as the final guardians of rights within their own systems. The second dimension concerns what is increasingly called #constitutional_identity. Article 4(2) TEU requires the EU to respect the national identities of member states, inherent in their fundamental structures. Constitutional courts in Germany, Italy, Austria, and elsewhere have used this provision, alongside their own doctrines of constitutional identity, to assert limits on the primacy of EU law. Deshko and Boiko (2024) examine these dynamics across multiple jurisdictions, finding that constitutional courts in these countries maintain that certain core elements of their constitutional orders — relating, for instance, to human dignity, democratic governance, or the separation of powers — cannot be overridden by EU law regardless of the Charter's primacy. The German Federal Constitutional Court's 'Right to Be Forgotten' judgments, analysed in detail by Rauchegger (2020), are particularly instructive: the Court adopted an approach in which it applies the Charter directly as a standard of constitutional review, but treats it as secondary to national fundamental rights in most cases, using it primarily to fill gaps where no equivalent national right exists. The third and perhaps most structurally significant dimension is the question of the scope of application of the Charter itself. Van Meerten (2026) examines a particularly revealing case study in the Netherlands, where pension disputes between beneficiaries and mandatory industry-wide pension funds fall outside the direct scope of judicial review under the national constitution. In such cases, EU law — including the Charter — becomes the sole effective avenue of legal protection. A restrictive reading of Article 51 CFR would leave individuals without any remedy; an expansive reading risks further blurring the already uncertain boundaries between EU law and national law. As Torres Pérez (2020) argues, the principle of effective judicial protection under Article 19(1) TEU is increasingly functioning as a backdoor mechanism through which the Charter's reach may be extended to member states beyond the formal boundaries of Article 51, with potentially far-reaching constitutional consequences. 4.4 Judicial Dialogue as a Structural Response Faced with these tensions, the EU's #multilevel_constitutional_system has developed a practice of #judicial_dialogue as its primary mechanism for managing disagreement. Rather than resolving conflicts through hierarchical imposition — a strategy that would be both politically dangerous and constitutionally questionable — the CJEU and national courts have developed habits of mutual reference, cooperation through the preliminary reference procedure, and what scholars describe as 'upstream' and 'downstream' forms of judicial interaction. Jarukaitis (2024) offers a particularly clear account of these dynamics, distinguishing between the 'upstream' role of national courts as guardians of EU-level values by referring questions to the CJEU, and the 'downstream' role of the CJEU in treating national courts as European courts that are cornerstones of the decentralised EU judicial system. This relational model of governance, in which national courts and the CJEU are understood as co-participants in a shared constitutional project rather than adversaries in a hierarchy, is theoretically appealing and practically important. Casarosa and Moraru (2022) similarly argue, in their comparative study of judicial interaction in the field of fundamental rights, that judicial dialogue has proved capable of answering complex legal questions relating to Charter implementation that no single court could resolve alone. Yet #judicial_dialogue has its limits. Wessel et al. (2020), in a joint statement signed by leading EU law scholars, warned that national courts cannot override CJEU judgments without destroying the basic architecture of the EU legal order. The Polish and Hungarian constitutional crises of the 2010s and 2020s illustrated that the limits of judicial dialogue can be breached when political actors capture constitutional courts and deploy them as instruments of resistance to EU law rather than as partners in a shared legal system. Sehnálek (2024) explores the full range of options available to constitutional courts in navigating conflicts with the CJEU, from full acceptance to outright rejection, and concludes that the architecture of European constitutionalism leaves space for legitimate disagreement but not for deliberate defection. 4.5 The Horizontal Dimension and Expanding Scope Beyond the vertical tension between EU and national levels, the Charter has generated important questions about its #horizontal_application — that is, its applicability in disputes between private parties rather than between individuals and public authorities. The Court of Justice has cautiously recognised that certain Charter provisions can produce direct effects in horizontal relationships, particularly in the areas of non-discrimination and social rights. Cases such as Egenberger (2018) and Bauer (2018) established that provisions of the Charter that are mandatory in character and unconditional can be applied directly between private parties, displacing conflicting national law. This development is potentially transformative. If the Charter can directly govern private employment relationships, it becomes a tool not merely for restraining public power but for reshaping the terms of private legal obligations throughout the EU. Niță and Salomia (2025), analysing recent CJEU jurisprudence on horizontal application, note both the liberatory potential of this development and its risks: an excessively expansive horizontal reading could destabilise the EU's #fundamental_rights regime by generating unpredictable obligations and undermining the principle of legal certainty. National courts — including those in Romania, whose perspective Niță and Salomia examine — find themselves required to act as judges of EU fundamental rights in private disputes, a role they have not always been trained or equipped to perform. Nagy (2024), writing in the German Law Journal, provides the most detailed theoretical reconstruction of what he calls the 'diagonal' application of the Charter — a mode of application that is neither straightforwardly vertical nor horizontal, but cuts across both dimensions depending on how closely a private relationship is connected to the implementation of EU law. Nagy argues that the CJEU's case law on this question has been amorphous and inconsistent with the Charter's constitutional mandate, and proposes a doctrine of 'displacement' as a more coherent organising principle. The lack of doctrinal coherence in this area is itself a symptom of the deeper structural tension identified by Douglas-Scott (2011): the Charter was grafted onto a legal system not designed with it in mind, and the joins are still showing. 5. Findings The analysis above yields several important findings about the evolution of #fundamental_rights in the EU legal order and the ongoing tensions generated by the Charter's binding status. First, the development of #EU_fundamental_rights was not the product of a single political decision or constitutional design. It was the cumulative result of judicial creativity, structural pressures from national constitutional courts, political bargaining in intergovernmental conferences, and the slow professionalisation of a European legal community committed to rights. This process is better explained by the combination of Bourdieu's legal field dynamics, world-systems structural pressures, and #institutional_isomorphism than by any narrative of rational constitutional planning. Second, the Charter's elevation to binding status by the Treaty of Lisbon was genuinely transformative, but its scope of application remains fiercely contested. Article 51 CFR's limitation to situations where member states are 'implementing Union law' has proved unstable in practice. The CJEU has interpreted this broadly; national courts have interpreted it narrowly; and the resulting gap in application has produced legal uncertainty for individuals, administrations, and courts alike (Vrabie, 2020; Van Meerten, 2026). Third, the tension between the Charter and national constitutional courts is structural, not merely doctrinal. It reflects a fundamental ambiguity in the EU's constitutional design: the EU claims to be a constitutional order with supreme law, while simultaneously claiming to respect national constitutional identities and the constitutional autonomy of member states. These claims are difficult to reconcile in cases of genuine conflict, and the EU's legal architecture provides no entirely satisfactory mechanism for doing so (Sehnálek, 2024; Galimberti and Ninatti, 2020). Fourth, #judicial_dialogue, while imperfect, represents the most promising structural response to these tensions. The practice of mutual reference between the CJEU and national courts, formalised through the preliminary reference procedure but extending well beyond it through informal channels of legal culture and professional exchange, has enabled the EU's #multilevel_rights_system to function despite its internal contradictions. The challenge is to deepen and institutionalise this dialogue in ways that do not require either side to abandon its fundamental commitments. Fifth, the expanding scope of the Charter — through its horizontal application and the CJEU's use of the principle of effective judicial protection — is the most dynamic and contested frontier of contemporary EU fundamental rights law. It raises questions about the ultimate ambition of the EU's rights project: does the Charter aspire to govern all legal relationships within EU law's orbit, or is it fundamentally a constraint on public power? The answer the CJEU gives to this question over the next decade will shape the future of #EU_constitutionalism as profoundly as the Lisbon Treaty itself. 6. Conclusion The story of #fundamental_rights in the EU legal order is, at its core, a story about the transformation of an economic organisation into something that increasingly resembles a constitutional polity. That transformation was achieved not through a single grand design but through the incremental accretion of judicial doctrine, Treaty revision, political compromise, and the structural pressures of institutional competition. The Charter of Fundamental Rights, now a binding part of primary EU law since 2009, represents the most visible symbol of this transformation — a document that codifies the Union's commitment to dignity, freedom, equality, solidarity, citizenship, and justice as legal obligations rather than mere aspirations. Yet, as Douglas-Scott (2011) observed at the moment of the Charter's entry into force, the achievement of binding status does not resolve the deeper tensions that have always attended #EU_fundamental_rights. The Charter exists in a crowded house, alongside national constitutions, the ECHR, and the general principles of EU law. Its relationship with national constitutional courts remains contested, its scope of application is disputed, and its horizontal reach is only beginning to be worked out. The frameworks of Bourdieu's #legal_field, world-systems theory, and #institutional_isomorphism all suggest that these tensions are not simply legal puzzles to be solved by more careful drafting or more consistent judging. They are the product of deep structural conflicts between different levels of legal authority in a political system that has not yet resolved its own constitutional foundations. The path forward lies in what this article has called genuine #judicial_dialogue — not the mere formality of preliminary references, but a substantive and ongoing conversation between the CJEU and national courts about the meaning, scope, and application of #fundamental_rights in a system that needs both supranational uniformity and national constitutional pluralism to function legitimately. Whether the EU's legal institutions can sustain and deepen that dialogue in conditions of political stress and democratic backsliding remains the central challenge of EU #constitutionalism in the coming decade. This article has offered a preliminary analytical framework for understanding these dynamics. More empirical research is needed on how specific national courts in different member states are actually applying the Charter in practice, and on the conditions under which #judicial_dialogue succeeds or fails in managing conflict between EU and national fundamental rights standards.

This article examines #European_law as a dynamic field of #institutional_power, #legal_integration, and evolving #sovereignty. Drawing on Pierre Bourdieu's concept of the #legal_field, #world-systems_theory, and #institutional_isomorphism, it analyses three interconnected dimensions of contemporary European Union law: the tension between #supranational_authority and #member_state_sovereignty; the challenge of #democratic_backsliding and #rule_of_law enforcement; and the emergence of #digital_regulation as a new site of legal ordering. Using qualitative documentary analysis of primary EU legal instruments and secondary scholarly literature, the article argues that EU law functions not merely as a technical body of rules but as a form of symbolic capital through which relations of power are structured, reproduced, and contested across a stratified legal space. The findings show that despite significant advances in regulatory capacity, persistent core-periphery asymmetries, institutional gaps in enforcement, and platform capture of legislative processes continue to constrain the EU legal order's capacity to deliver on its foundational values. The article contributes to socio-legal scholarship by integrating structural sociology with doctrinal EU law analysis. Keywords: European Union law, institutional isomorphism, Bourdieu, world-systems theory, digital regulation, rule of law, democratic backsliding, sovereignty, platform governance 1. Introduction For more than six decades, #European_law has served as the backbone of the most ambitious #regional_integration project in modern history. What began as a set of economic agreements among six Western European states has grown into a comprehensive legal architecture binding twenty-seven member states across areas as diverse as competition policy, fundamental rights, environmental standards, criminal cooperation, and — most recently — the governance of digital platforms. Yet as the body of EU law has expanded in scope and ambition, so too have the tensions that run through it. The #Treaty_of_Rome, signed in 1957, contained within it both an integrationist impulse and a deep ambiguity about how far that integration should go. Today, that ambiguity has not been resolved — it has deepened. The concept of an '#ever_closer_union' sits uneasily alongside renewed assertions of #national_sovereignty from member states such as Hungary and Poland. The supremacy of EU law, established through landmark rulings of the #European_Court_of_Justice, is contested by national constitutional courts that refuse to accept EU law as the final word on their domestic legal orders. The expansion of #digital_single_market regulation — through instruments like the #General_Data_Protection_Regulation (GDPR), the #Digital_Services_Act (DSA), and the #Digital_Markets_Act (DMA) — represents a genuine global first in #platform_governance, yet critics argue that much of this regulation has been captured by the very platforms it sought to constrain (Kausche and Weiss, 2024). This article approaches these tensions through three theoretical lenses: Pierre Bourdieu's sociology of the #legal_field, #world_systems_theory as applied to European integration, and the concept of #institutional_isomorphism drawn from organisational sociology. These frameworks, taken together, allow us to move beyond purely doctrinal description and to ask structural questions: Who benefits from the current shape of European law? How are legal norms produced, circulated, and resisted? What forces push member states toward convergence, and what forces pull them apart? The article proceeds as follows. Section 2 provides a background and theoretical framework, setting out the three analytical tools used. Section 3 describes the methodological approach. Section 4 presents a three-part analysis covering sovereignty and constitutional identity, rule of law enforcement, and digital regulation. Section 5 draws together the main findings, and Section 6 offers conclusions. 2. Background and Theoretical Framework 2.1 Bourdieu and the Legal Field Pierre Bourdieu's concept of the 'field' offers a powerful tool for understanding the structure of #legal_institutions. For Bourdieu, a field is a relatively autonomous social space organised around a specific form of capital — in the case of law, legal capital, which takes the form of recognised expertise, formal credentials, institutional position, and the ability to produce authoritative interpretations of legal texts. Within any legal field, agents compete to accumulate this capital, and those who succeed gain the power to define what counts as legitimate law (Kretschmann, 2025). Applied to #EU_law, this framework reveals something important. The EU legal field is not a neutral space of rule-following; it is a contested arena in which the European Court of Justice, the European Commission, national governments, multinational corporations, civil society organisations, and legal academics all compete to shape the meaning and direction of European law. When, for example, the ECJ declares a principle of #EU_law_supremacy, it is simultaneously making a legal argument and asserting institutional power — claiming for itself the highest position in the #field of European legal authority. Bourdieu's concept of '#habitus' is equally relevant here. The habitus refers to the deeply ingrained dispositions — of thought, perception, and action — that agents acquire through their position in a social field. A study by Esmark (2025) illustrates this vividly: using the concept of 'allodoxia', the article shows how Danish jurists in the late 1980s drafted a buy-Danish clause that was a clear breach of EU law, not out of bad faith, but because their habitual dispositions — formed within a national legal field — led them to misrecognise what EU law actually required. This structural tension between national legal habitus and EU legal norms is not merely a story of error; it is a recurring feature of how EU law operates within member states. More broadly, Caserta and Madsen (2026) argue that legal globalisation today must be understood as a contested transnational field, structured by struggles over authority, symbolic capital, and competing visions of legitimacy. Drawing explicitly on Bourdieu's field theory, they show how global legal vocabularies and institutions continue to operate, but increasingly as arenas of polarised conflict rather than vehicles of normative convergence. This insight applies with particular force to EU law, which increasingly finds itself navigating between a liberal-integrationist vision on one hand and the claims of illiberal nationalism on the other. Connecting Bourdieu's field theory to neo-institutional sociology, Zhao and Ge (2023) develop a framework showing that the very institutional mechanisms causing #isomorphism — regulative forces, normative pressures, and cognitive processes — also generate systematic status differentiation among organisations via their different levels of capital, homologous structures, and various habitus. This is a crucial insight for EU legal studies: the pressures pushing member states toward legal convergence simultaneously reinforce hierarchies between them. 2.2 World-Systems Theory and the Core-Periphery Structure of EU Law #World_systems_theory, developed by Immanuel Wallerstein, conceptualises the global political economy as a hierarchically structured system divided into core, semi-periphery, and periphery zones. Core zones concentrate capital, technology, and sophisticated institutional infrastructure; peripheral zones are structurally subordinated to the core through patterns of unequal exchange. Applied to European integration, this framework highlights the deep structural inequalities that European law both reflects and reproduces. Laffan (2021) traces how the EU addressed its treaty commitment to 'harmonious development' through a series of significant phases, arguing that every major development in the EU, with the exception of the euro, was accompanied by policy provisions designed to alleviate divergence between core and periphery. Yet despite these provisions, economic and social differences have not diminished. Czubocha (2023) argues that there is an unofficial stratification within the EU based on cultural and economic differences, with Western core states — France and Germany in particular — constituting a higher stratum while post-communist member states occupy a subaltern status. This unofficial stratification, he contends, results in a differentiated impact of EU policies on the interests of member states. Simonazzi (2020) applies the Latin American historical-structuralist approach to European integration, arguing that the structural causes of the Eurozone crisis can be understood in terms of the divergent trajectories of interdependent economies with different productive capabilities. The new challenges confronting the EU — digital transformation, reversal from globalisation to regional blocs, disenchantment with the European project — call, in his view, for a radical change in the institutional and productive structures of the Eurozone. Portella-Carbó and Boixadera (2025) extend this analysis, finding that Southern European peripheral economies have had to rely on foreign-led recovery to improve their external positions after the Global Financial Crisis, forcing them into a state of semi-permanent austerity that postpones convergence to the EU core. For EU legal scholars, the significance of these economic patterns is that European law cannot be understood in isolation from the structural conditions in which it operates. The rule of law, the single market, and the EU's regulatory agenda are not neutral projects; they are shaped by and contribute to the reproduction of core-periphery hierarchies within the European space. 2.3 Institutional Isomorphism and EU Law The concept of #institutional_isomorphism, developed by DiMaggio and Powell, identifies three mechanisms by which organisations come to resemble one another: coercive isomorphism (imposition through regulation or authority), normative isomorphism (standardisation through professional communities), and mimetic isomorphism (copying in the face of uncertainty). Applied to EU law, these mechanisms help explain both the convergence of member states' legal systems and the resistance that convergence provokes. Eriksen (2024) argues that what makes EU law binding is not a sovereign's monopoly on power at the European level, but the fact that a public coercive framework has been established which aims at solving the indeterminacy and assurance problems facing international cooperation — a classic case of #coercive_isomorphism at work. Yet because the Union falls short of meeting certain democratic standards, oversteps competences, and is plagued with inertia, there is, in his view, a call for constitutional reform. The role of the European Court of Justice in driving isomorphism through law is highlighted by Agha (2024), who argues that bodies such as the ECJ have expanded their roles — promoting '#integration_through_law' to counter alternative political projects — giving rise to what he calls 'anti-populism' as a discursive tool. This constitutionalisation process, he argues, subtly coerces member states and citizens into accepting EU norms and values, shaping perceptions of normalcy and inevitability. The exclusive focus on legalistic interpretations, he contends, obscures the underlying structural factors perpetuating power dynamics and economic disparities among member states. 3. Method This article employs #qualitative_documentary_analysis as its primary method. This approach is well-suited to the study of legal texts, institutional documents, and scholarly commentary, allowing the researcher to trace patterns of meaning, identify contradictions, and situate legal arguments within their broader social and political context. The primary source materials examined include the Treaty on European Union (TEU), the Treaty on the Functioning of the European Union (TFEU), the EU Charter of Fundamental Rights, and key secondary legislation — including the GDPR (Regulation 2016/679), the Digital Services Act (Regulation 2022/2065), the Digital Markets Act (Regulation 2022/1925), and Regulation 2020/2092 on a general conditionality regime for the protection of the Union budget (the Rule of Law Conditionality Regulation). Landmark decisions of the European Court of Justice, including cases on the supremacy and direct effect of EU law, are also considered. Secondary sources were selected through a systematic review of peer-reviewed literature published between 2020 and 2026, using academic databases with queries covering EU institutional law, digital regulation, rule of law enforcement, Bourdieu's legal sociology, and world-systems theory applied to European integration. Priority was given to articles published in Q1 and Q2 journals as ranked by Scimago. Theoretical integration was achieved by reading the primary legal materials through the analytical lenses established in Section 2. 4. Analysis 4.1 Sovereignty, Constitutional Identity, and the Limits of Supranational Authority The relationship between EU law and the #sovereignty of member states remains one of the most contested questions in European legal thought. Pace (2024) clarifies that neither the dualist theory — which treats EU law and national law as entirely separate orders — nor the monist theory — which treats EU law as superior by virtue of the constitutional-state paradigm — adequately captures the reality of how the Union actually functions. To properly understand this relationship, he argues, one must look at what the positive law contained in the Union Treaties, as desired by member states and interpreted by the Court of Justice, actually provides. The result is a legally hybrid arrangement that defies simple categorisation. Karakamisheva-Jovanovska (2023) traces how the concept of an 'ever closer Union' has evolved in tension with member states' desire to safeguard national interests. The Treaty of Lisbon reaffirmed commitment to this concept while aligning decisions with citizen concerns — yet a series of crises, from the Eurozone collapse to the pandemic to the war in Ukraine, have intensified this tension. The paper contends that the EU's responses to crises have revealed the fault lines between supranational integration and national sovereignty, and that the role of the European Parliament in navigating these tensions remains crucial and underappreciated. From the perspective of Bourdieu's field theory, this tension can be understood as a struggle over symbolic capital within the European legal field. The ECJ seeks to consolidate its position as the highest authority in the field, while national constitutional courts — from Germany's Federal Constitutional Court to Hungary's Constitutional Court — assert their own competing claims to #constitutional_identity. Zelger (2026) argues that the neoliberal architecture ingrained in the EU legal framework and in the ECJ's case law has created a situation of socio-economic imbalance that is politically destabilising. Since Treaty change is, realistically, off the table, she argues that the Court should develop a new self-understanding that replaces the 'integration through law' paradigm with something that could be understood as 'integration sustained by law' — a formulation that acknowledges the limits of purely legal solutions to political and economic problems. The rise of right-wing populist parties further complicates this picture. Popov (2025) shows that most right-wing populist parties across EU member states have — rather than demanding outright withdrawal from the Union — conditioned their countries' continued stay on a revision of the current model of integration, its legal nature, and its supranational mechanisms. They demand a stop to federalisation, a return of full sovereignty to member states, and a transformation of the EU into a decentralised alliance using mechanisms of subsidiarity and unanimity. While this agenda has not yet succeeded in reshaping EU law, it exerts persistent pressure on the #institutional_field, shifting the balance of forces and forcing the EU institutions into increasingly defensive postures. 4.2 Democratic Backsliding and Rule of Law Enforcement The most acute institutional crisis facing EU law today is the phenomenon of #democratic_backsliding within the Union itself. Since the early 2010s, both Hungary and Poland have enacted systematic legislative and constitutional changes that, in the assessment of the European Commission and the ECJ, violate the foundational values enshrined in Article 2 of the TEU, including the #rule_of_law, democracy, and the independence of the judiciary. Priebus (2022), writing in the Journal of Common Market Studies, offers a systematic analysis of the Commission's response, arguing that the EU's tools — the Justice Scoreboard, the Rule of Law Framework, and the Rule of Law Mechanism — are characterised by a fundamental mismatch between the causes of the problems identified and the solutions chosen. Instead of sanctioning voluntary noncompliance, they rely on soft measures recommended for cases of involuntary noncompliance, which are entirely unsuited to cases of deliberate, politically motivated backsliding. Only the Rule of Law Conditionality mechanism, linking the disbursement of EU funds to respect for the rule of law, introduces genuine enforcement leverage. Holesch and Portela (2024) test the effectiveness of the EU's sanctions toolbox — comprising the Article 7 TEU mechanism, infringement procedures, and funding conditionality — and find that both infringement procedures and funding conditionality are only partially effective. Their analysis points to two determinants of sanction effectiveness: the credibility of sanctions imposition and their economic costs. The Article 7 TEU mechanism, which can in principle lead to the suspension of a member state's voting rights, has proven politically paralysed because it requires unanimous agreement among other member states — a condition that has never been met, as Hungary and Poland have blocked each other's proceedings. Blanke and Sander (2023) document how, in Poland, the ruling PiS government's judicial reforms — forced retirements, disciplinary proceedings, political appointments of judges — exposed the judiciary to legislative and governmental control, while the Polish Constitutional Tribunal's declaration that EU primary law was unconstitutional represented an open departure from the common values enshrined in Article 2 TEU. Bard and Kazai (2022) argue, in response, that the ECJ missed an opportunity by focusing exclusively on substantive rule-of-law violations — the quality of democracy and the protection of rights — rather than also engaging formal rule-of-law arguments about predictability, non-retroactivity, and procedural regularity, where the violations are even clearer and harder to contest. From a world-systems perspective, the geographical distribution of rule-of-law problems is striking. Democratic backsliding has occurred overwhelmingly in the newer, post-communist member states of Central and Eastern Europe, precisely those states that occupy a semi-peripheral position in the EU's economic geography. Mavrouli (2024) argues that the EU's financial and techno-managerial strategy for rule-of-law protection — combining the European Semester, the Conditionality Regulation, the European Structural Investment Funds, and the Recovery and Resilience Facility — is characterised by a mismatch between the causes of the problems and the solutions chosen, and that only measures that genuinely induce rule conformity, rather than those designed to deter violations, can address backsliding. Through an institutional isomorphism lens, the backsliding phenomenon reveals the limits of normative and mimetic isomorphism as mechanisms for securing legal compliance. When the political incentives of governing elites diverge sharply from the norms that the EU seeks to impose, neither professional socialisation nor the copying of 'best practice' models can substitute for genuine coercive capacity. The EU, by design, lacks a monopoly on coercive force within its member states — and this structural feature of the legal order shapes and constrains every enforcement mechanism available to it. 4.3 Digital Regulation as a New Site of Legal Ordering The third dimension of contemporary European law examined in this article is the emergence of an ambitious regulatory framework for the #digital_economy. Since the adoption of the GDPR in 2016, the EU has constructed what Pathak (2024) calls a comprehensive 'data governance' architecture — spanning the Digital Markets Act, the Digital Services Act, the Data Governance Act, the Data Act, and the AI Act — which together represent the most ambitious and broad regulatory project in the field of data and digital services regulation worldwide. The DSA, in particular, introduces a comprehensive set of rules regulating #very_large_online_platforms (VLOPs). Iliopoulou-Penot (2025) argues that, contrary to the characterisation of the DSA as a tool for censorship, the regulation actually protects freedom of expression online by establishing a new model of governance built around three key objectives: fostering knowledge and resilience through risk management; enhancing fairness in and of content moderation practices; and embedding social media companies into a structured system of oversight. Yet the process through which the DSA was produced reveals the dynamics of #platform_power that Bourdieu's field theory would predict. Kausche and Weiss (2024) trace Google and Meta's activities during the DSA's legislative process from its announcement in 2020 to its adoption in 2022, arguing that platforms prevailed thanks to their ability as intermediaries to quietly shape the available policy options. Their 'platform power mechanism' combines institutional and ideational sources of business power — drawing on their entrenched position as indispensable providers of essential services and promoting the idea of themselves as responsible and neutral intermediaries. The DSA, in this reading, legitimised and institutionalised platforms' position as gatekeepers of the internet rather than genuinely constraining it. Griffin (2025) offers a complementary critical analysis, arguing that the systemic risk framework embedded in the DSA — which requires large online platforms to assess and mitigate risks to fundamental rights, public health, civic discourse, and wellbeing — tends, by its very nature, to depoliticise distributive and ideological conflicts, privilege technocratic expertise, and delegate primary responsibility for identifying and managing risks to the regulated companies themselves. This institutional design, she argues, will be highly favourable to the interests of the powerful multinational corporations the DSA seeks to regulate. Rampásek and Mesarčík (2025) identify a further gap: EU law lacks a coherent legal framework that adequately defines, protects, and empowers cybersecurity researchers, particularly those operating outside formal institutions. The DSA's structure is better suited for systemic risk research than for adversarial, exploratory cybersecurity testing — pointing to the difficulty of designing regulation that can keep pace with the rapidly evolving #digital_landscape. From the perspective of institutional isomorphism, the digital regulatory agenda represents a striking example of coercive isomorphism operating at the global level. The EU's regulatory standards have begun to exert a so-called 'Brussels effect', pulling non-EU platforms and jurisdictions toward compliance with EU norms not because they are required to, but because the cost of maintaining different standards for different markets is prohibitive. Yet this very success masks the capture dynamic: as #platform_governance_standards converge around EU norms, those norms are themselves shaped by the platforms that have the greatest resources to participate in the legislative process. Enescu (2023) and Leistner (2021) both highlight the regulatory complementarity and tensions between the DSA and DMA — the former targeting illegal content and platform transparency, the latter targeting structural market power of gatekeeper platforms. Both agree that the coordination between these instruments and existing European competition law remains underdeveloped, creating risks of disharmonisation and enforcement gaps, particularly at the interface between EU-level enforcement and national remedies. 5. Findings The analysis presented in this article produces four main findings. First, #EU_law operates as a form of symbolic capital within a contested transnational legal field, in Bourdieu's sense. The ECJ's authority is not self-grounding; it depends on the continuous recognition of that authority by the relevant actors — member state governments, national courts, legal professionals, and citizens. When that recognition is withdrawn or challenged, as in the Polish constitutional crisis, the legal order faces not merely a doctrinal problem but a legitimacy crisis that cannot be solved through legal means alone. Second, the structural inequalities between EU member states — historically traceable to their position in the European core-periphery hierarchy — shape both the production and the reception of EU law. The rule-of-law crisis is not randomly distributed across the EU's membership; it is concentrated in the semi-peripheral states of Central and Eastern Europe, where the conditions for #democratic_consolidation were always more fragile and where EU accession was accompanied by structural economic pressures that continued to disadvantage domestic producers and institutions. Third, the EU's enforcement mechanisms for its foundational values remain structurally weak in the face of deliberate, politically motivated noncompliance. The mismatch between management-based soft measures and the coercive capacity needed to deter or reverse genuine backsliding is not an accident — it reflects the fundamental tension between the intergovernmental character of the EU's constitutional architecture and the supranational ambitions of its foundational values. Fourth, the digital regulatory agenda represents a genuine and significant innovation in European law — an attempt to construct new forms of #public_governance over privately controlled digital infrastructure. Yet this agenda has been shaped from the outset by the power resources of the platforms it seeks to regulate, and the institutional design of the DSA in particular embeds mechanisms that are likely to reproduce, rather than transform, the dominance of large tech platforms in the digital public sphere. 6. Conclusion European law stands at a moment of profound and interconnected tensions. The #constitutional_architecture of the EU, the #rule_of_law mechanisms designed to protect its foundational values, and the new digital regulatory framework all face challenges that are at once legal, political, and structural. This article has argued that understanding these challenges requires more than doctrinal analysis. Drawing on Bourdieu's sociology of the legal field, world-systems theory, and institutional isomorphism, it has shown that EU law is best understood as a site of ongoing competition over symbolic capital, shaped by structural inequalities between core and peripheral member states, and constrained by the limits of coercive capacity in a legal order that remains, at its base, dependent on the voluntary compliance of sovereign states. Zelger (2026) is right that the replacement of 'integration through law' with 'integration sustained by law' would require the EU's courts and institutions to develop a new self-understanding — one that acknowledges the political and economic conditions in which law operates rather than treating legal norms as self-executing. Whether that reorientation is politically achievable, given the current distribution of power within the EU's institutional field, remains genuinely uncertain. What is clear is that the formal architecture of European law — its treaties, regulations, directives, and court judgments — will continue to be the terrain on which the EU's deepest political conflicts are fought out. The #Digital_Services_Act, the #Rule_of_Law_Conditionality, the debate over Treaty reform — each of these is simultaneously a legal instrument and a political settlement, reflecting and reproducing the relations of power that constitute the European legal order at any given moment. Understanding those relations, rather than taking the legal text at face value, is the essential task of critical European legal scholarship. This article is based on a focused review of recent literature and primary legal materials; broader systematic searches could surface additional comparative work, particularly on non-EU European legal orders and on the EU's external legal relations.

This article examines #international_law not as a neutral regulatory system but as a contested #field_of_power in which historical asymmetries, institutional pressures, and competing visions of #legitimacy shape the behaviour of states and non-state actors alike. Drawing on Pierre #Bourdieu's field theory and the concept of #symbolic_capital, #world-systems_theory, and #institutional_isomorphism, the article argues that the international legal order reflects and reproduces structural inequalities between #core_states and #peripheral_states. Rather than operating as a level playing field of sovereign equals, #international_law functions as an arena in which powerful actors accumulate and deploy legal capital while weaker states face coercive conformity or marginalisation. Through a qualitative analysis of scholarship published between 2020 and 2026, the article identifies three interlocking dynamics: the #legal_field as a site of elite reproduction, the world-system as the structural backdrop against which legal norms are produced and enforced, and #isomorphism as the mechanism through which conformity is extracted from peripheral states. The article concludes that meaningful reform of the international legal order requires confronting, not merely acknowledging, these structural conditions. Keywords: #international_law, #Bourdieu, #world-systems_theory, #institutional_isomorphism, #global_governance, #legitimacy, #Global_South, #sovereignty, #power_asymmetry, #legal_field 1. Introduction The proposition that #international_law governs the relations between states on the basis of sovereign equality is among the most frequently repeated in all of legal scholarship. It is also among the most challenged. Formal declarations of equality among states coexist with observable hierarchies of enforcement, influence, and norm-making. Some states write the rules; others are expected to follow them. Some states invoke international courts when convenient and ignore them when not. The gap between the law on paper and the law in practice is not a marginal problem — it is structural. This article approaches that gap through three complementary theoretical lenses. Pierre #Bourdieu's field theory, developed most fully in his sociology of law and his broader analysis of social fields, allows us to ask who holds the #symbolic_capital that confers authority in the international legal order, and how that capital is accumulated and converted into legal legitimacy. #World-systems_theory, associated principally with the work of Immanuel Wallerstein, directs attention to the position of states within the global #capitalist_world-system as a determinant of their capacity to shape or resist international legal norms. #Institutional_isomorphism, developed in organisational sociology by DiMaggio and Powell, explains the pressures that drive weaker actors to adopt the forms and procedures of dominant legal models — not necessarily because those forms are effective, but because conformity is the price of recognition. The argument that follows is not that #international_law is simply and uniformly a tool of the powerful — that position, though not without evidence, forecloses the complexity and genuine contestation that takes place within and around the international legal field. Rather, the article argues that the international legal order is a structured space of contestation in which the starting positions are deeply unequal, the rules of the game were largely written by dominant actors, and the very grammar of legal argument carries the residue of a #colonial past that has not been superseded by formal decolonisation. The article proceeds as follows. Section 2 reviews the theoretical framework. Section 3 describes the methodological approach. Section 4 analyses key dynamics in the literature. Section 5 presents findings. Section 6 concludes with implications for reform. 2. Background and Theoretical Framework 2.1 Bourdieu and the Legal Field Pierre Bourdieu's sociology offers some of the most precise tools available for analysing how legal authority is produced, distributed, and contested. In his concept of the field, Bourdieu described a relatively autonomous social space structured by the distribution of different forms of capital — economic, social, cultural, and symbolic. A field is not simply a domain of activity; it is a space of positions, and agents within it compete over the definition of what counts as legitimate knowledge, legitimate authority, and legitimate practice. When Bourdieu's framework is applied to #international_law, the insights are uncomfortable and productive. The international legal field is not simply a venue in which pre-formed state interests are negotiated; it is a space in which certain actors — elite jurists, powerful states, leading international institutions — hold disproportionate stocks of #symbolic_capital and use that capital to define the rules of acceptable legal argument. Caserta and Madsen (2026) describe the contemporary international legal order as a #contested_transnational_field structured by struggles over authority, symbolic capital, and competing visions of legitimacy, drawing explicitly on Bourdieu to show how global legal vocabularies continue to operate but increasingly as arenas of polarised conflict. The seemingly neutral procedures of international courts and treaty bodies are, in this reading, mechanisms through which accumulated legal capital confers advantages on those actors who have the expertise, the networks, and the institutional position to speak the language of international law fluently. Christensen (2023) brings this framework to bear on international criminal justice, showing through an empirical analysis of elite agents active in the field that different types and volumes of capital structure relations between elites as well as between the field of international criminal justice and the state. The field of international criminal justice, he argues, constitutes a competition over the value and control of capital that plays out at the borders between the national and the international. The state does not necessarily control power over state capital; when its elites no longer reproduce its meta-capital, the state loses the semblance of being a unified actor on the world stage. This is not merely an academic observation — it has direct implications for how we understand the differential treatment of powerful and weak states before international tribunals. Oskanian (2023), working in International Studies Quarterly, takes Bourdieu's field theory toward the broader question of international order, conceptualising the international social space as an anarchic meta-field created by outward projections of power and practice by state nobilities. His framework allows for the widest range of international orders based on specific configurations of capital, and varying forms of practice. Taken together, these contributions establish that Bourdieu's sociology is not a peripheral addition to international legal analysis — it is a rigorous framework for revealing the structured inequalities that formal legal doctrine tends to conceal. 2.2 World-Systems Theory and the Hierarchy of International Law #World-systems_theory, in its application to #international_law, begins from the observation that states are not simply formal equals in an anarchic system; they occupy positions within a hierarchically organised world economy in which core states exercise structural dominance over peripheral and semi-peripheral states. This hierarchy shapes not only economic exchange but also the production and enforcement of legal norms. Demirel (2026), writing in World Affairs, examines the phenomenon of hegemonic rivalry and evaluates international law from the perspective of world-systems analysis. He argues that since the decline of US hegemony in the 1970s, a hegemonic crisis has emerged within the capitalist world-system, and that this crisis has transformed international law into an arena of fierce competition between core states seeking to maintain the status quo and rising powers seeking to revise it. The United States and other core states have attempted to use international legal frameworks to protect established hierarchies, while China and Russia seek to challenge or revise those frameworks. International law, in this account, is not above geopolitics — it is saturated with it. Sahin and Güneysu (2025) make a stronger claim: that #international_law, deeply embedded in the history of capitalism, actively reproduces underdevelopment. Colonial primitive accumulation turns the legal form into international law. The historical connection between colonisation and international law demonstrates the inability of international law to prevent and combat underdevelopment and its active role in perpetuating global inequalities by protecting colonial wealth through the use of property rights. This argument connects legal form to the dynamics of capital accumulation in a way that Bourdieu's field theory and world-systems analysis both illuminate from different angles. Suedi (2021) makes a related but more measured point: the inequality of nations seeps into the practice of international law, making the latter an arguably challenging tool for developing countries to achieve their socio-economic objectives. The language is careful, but the implication is clear. The international legal system that proclaims sovereign equality does not deliver it. Perrone (2022) examines the international trade order through this lens, arguing that international trade law does little to help countries in the Global South achieve economic development — and may even obstruct it. The most important laws for the capitalist industrialisation of Western countries were not those of private property, contracts, or free trade but those related to colonial long-distance trade. This historical argument has a structural implication: the absence from contemporary international trade law of any effective vocabulary for modifying the international division of labour is not accidental — it reflects the interests of those who wrote the rules. 2.3 Institutional Isomorphism and Coercive Conformity #Institutional_isomorphism, as developed by DiMaggio and Powell in their classic formulation, describes the processes by which organisations in a field come to resemble one another over time. The three mechanisms — coercive, mimetic, and normative — together explain why formal compliance with dominant institutional models spreads even when those models are not demonstrably effective. Applied to #international_law, isomorphism captures a dynamic that world-systems theory identifies structurally and Bourdieu maps sociologically: peripheral states adopt the legal forms of dominant actors not because those forms serve their interests, but because conformity is the condition for inclusion in international society. Ilevbare and McPherson (2025), in an article published in the International Journal of Sport Policy and Politics, illustrate mimetic isomorphism in a concrete domain: they observe that sports organisations like FIFA and the IOC are increasingly resembling political institutions, and that isomorphism in the context of sportswashing represents forced conformity when politics muscles sports organisations. The mechanism they describe — where weaker actors mimic dominant institutional forms to maintain legitimacy — applies more broadly to state behaviour in international legal contexts. States adopt treaty frameworks, dispute resolution procedures, and compliance reporting mechanisms because these are the institutional forms recognised as legitimate within the international legal field, regardless of whether they are well-suited to the actual governance needs of the adopting state. This dynamic is visible in the investment arbitration system, where Kalyanpur and Newman (2020), writing in Perspectives on Politics, document how the financialisation of international investment law transformed Investor-State Dispute Settlement into what they describe as a speculator's game. Their field-theoretic analysis shows how individuals from different fields — finance and law — interact and produce institutional changes that serve dominant actors and impose costs on states, particularly developing states, that the creators of the system did not anticipate. The privatisation of enforcement mechanisms within international law is not a neutral evolution — it reflects the preferences of actors with the capital to exploit the system. Meanwhile, global compliance institutions — the OECD, the WTO, the FATF — function not only as rule-makers but as assessors of rule-following, creating hierarchies of compliance in which the standards themselves encode the interests of powerful states (Олійник and Куш, 2026). This is isomorphism in action at the systemic level: the form of legitimate global governance is defined by those who set the standards, and others must conform or face marginalisation. 3. Method This article employs a qualitative, theoretically oriented methodology grounded in systematic engagement with recent scholarly literature. Sources were drawn from peer-reviewed journals, scholarly monographs, and book chapters published between 2020 and 2026, with particular attention to work appearing in Q1 and Q2 journals as ranked by Scimago. The selection criteria prioritised works that explicitly engaged with questions of power, legitimacy, and structural inequality in the international legal order, and that employed or directly engaged with at least one of the three theoretical frameworks — Bourdieu's field theory, world-systems theory, or institutional isomorphism. The methodological approach is that of critical discourse analysis applied to secondary legal and social-scientific literature. Rather than reviewing the holdings of international courts or the text of treaties, the article takes the scholarly conversation about #international_law as its primary object of analysis. This approach is justified by the article's central claim: that the theoretical vocabulary used to describe and evaluate the international legal order is itself a site of struggle — a claim derived directly from Bourdieu's insight that the production of legitimate knowledge about law is part of the operation of the legal field itself. No empirical primary data collection was conducted. The article instead synthesises and critically analyses the arguments of other scholars, identifying patterns across the literature that are not visible within any single contribution. This is a form of theoretical triangulation — the convergence of independent analytical frameworks on a common set of structural observations strengthens the confidence with which conclusions can be drawn. One limitation of this approach is that the literature reviewed, while carefully selected, remains a sample of a much larger body of scholarship. The geographic and linguistic distribution of sources is weighted toward English-language publications, which themselves tend to reflect institutional locations in the Global North — an irony that the article explicitly acknowledges and that the theoretical framework itself renders visible. 4. Analysis 4.1 The Field and Its Gatekeepers One of the most productive insights that Bourdieu's framework brings to #international_law is the concept of the legal expert as an agent who converts scholarly authority into practical legal power. Christensen and Madsen (2023) describe legal knowledge and expertise as a driving force in international governance systems, arguing that elite jurists and networks of legal experts function as transnational power brokers. These experts do not simply interpret law — they shape the creation of new international adjudicatory institutions, their legal frameworks, and their normative goals. The production of international law is concentrated in the hands of a relatively small professional community, and access to that community follows the contours of existing inequality. Vauchez and Daho (2020), in their analysis of the work of Yves Dezalay, describe how the globalisation of law is produced through the internationalisation strategies of national elites and the transformation of forms of state knowledge. Dezalay's empirical work — tracking the careers of lawyers, economists, and consultants who move between national and international legal institutions — reveals that the #globalisation of law is not a process that happens to states but one that is actively produced by actors with sufficient capital to operate across multiple fields simultaneously. This has implications for the question of who can effectively use #international_law. Bachand (2023) argues that law functions as a powerful tool for promoting the reproduction and legitimation of subordination, operating through four distinct moments: when law structures society, when rules and institutions are formally used, when law influences ideological positions, and when law is used to defend political claims. The Bourdieusian reading here is straightforward: the rules of the game are not neutral, and those who lack the capital to play the game well — whether because they lack expert lawyers, established institutional relationships, or the financial resources to sustain lengthy legal proceedings — face structural disadvantages that formal procedural equality does not address. Ruiz Abou-Nigm (2024), writing in the Journal of Private International Law, employs the striking metaphor of 'super highways' and 'jungle tracks' to describe the differential access to transnational justice that characterises the relationship between the Global North and Global South. Channelling legal proceedings justiciable in the Global South to courts in the Global North, she argues, creates systemic asymmetries that undermine the goal of justice for all — a goal nominally served by the international legal order. 4.2 The World-System and the Grammar of Inequality One of the most consistent findings across the literature reviewed is that the historical relationship between #colonialism and international law has not been resolved by formal decolonisation. Adelman and Paliwala (2020) argue that colonial principles of governance are elevated to principles of global governance after the end of the world wars, and that viewing international law from the standpoint of colonial histories reveals the present period based on sovereign equality of states to be not less imperial than past empires. The diffusion thesis — the idea that international law spread from a European centre to a colonial periphery — abstracts legal consciousness from social consciousness and removes anti-colonial resistances from accounts of the histories of international law. D'Souza (2020) makes the same argument in a more targeted way, focusing on South Asia to show that contemporary law and development under the UN system is a geo-historically constituted regime where law and legal norms are institutionalised to sustain unequal relations between states and privilege transnational corporations. The legal-institutional regime builds on principles of colonial governance, especially the system of Indirect Rule, and continues to reproduce colonial relations in new forms. Becker Lorca (2023), writing in International Affairs, shows that this structural inequality is actively resisted by states from the Global South, who have devised legal strategies to circumvent opposition to redistribution. Rather than appealing only to common goals and cosmopolitan theories, developing countries have sought redistributive opportunities within existing international law by using their sovereign entitlements to pursue what he calls combative solidarity. This is an important corrective to readings that see peripheral states as purely passive recipients of legal norms — the field is contested, even if the starting positions are unequal. Khalid (2025) examines the broader pattern of how hegemonic states engage with #international_law, arguing that the most prevalent trend seen among dominant powers is the substitution of home legal systems that better facilitate formal hierarchies, instrumentalisation, and retreat from international norms. Strong states derive their legitimacy from international law but must disassociate themselves from authority to maintain that legitimacy — a paradox that the Bourdieusian framework renders visible: the game can only be played if players accept its rules, yet the most powerful players are also the most able to rewrite the rules when those rules become inconvenient. 4.3 Compliance, Enforcement, and the Selective Rule of Law The question of #compliance is where the tension between the formal promise and the structural reality of #international_law becomes most visible. Scicluna (2021) provides a comprehensive overview of explanations for international law compliance, grouping them into instrumentalist explanations — states comply because it is in their interest — and normative explanations — states comply because they accept the obligation as legitimate. The enforcement of international legal obligations is, he notes, shaped by the condition of international anarchy and the principle of self-help. Wajahat, Jan, and Naz Ali (2025) analyse case studies including the US and the ICC, China's rejection of the South China Sea ruling, and humanitarian interventions in Kosovo and Syria, and conclude that selective compliance and political manipulation by powerful states characterise the enforcement of #international_law. The asymmetries in enforcement are not incidental — they reflect the structure of the international legal field, in which those with the most capital are also those with the least compulsion to comply. Patelisio (2025) focuses specifically on customary international law, arguing that it is not a product of collective consent but rather the outcome of political interests of powerful states. The persistent objector doctrine, which theoretically allows states to exempt themselves from customary norms they have consistently rejected, provides limited protection in practice. The formation of customary norms reflects the concentration of legal capital in the hands of states that are most active in international practice. Kucik, Peritz, and Puig (2024) document this dynamic at the WTO, showing how the Appellate Body modified its interpretations to promote compliance — but that this process is incremental and may not happen quickly enough, leading to backlash against international courts. The tensions between consistency and adaptation that legal institutions face are not merely technical; they reflect the political conditions in which powerful states demand flexibility for themselves while expecting consistency from others. Prieto-Ríos (2021) makes the sharpest version of this argument, contending that the international investment law system was the result of a colonial project within a capitalist system that has been influenced by developmentalism discourse and neoliberal ideology, becoming an instrument that facilitated forms of systemic violence against Third World countries. This is not merely a critical theory position — it is grounded in the material consequences of investment arbitration for states that have faced rulings requiring compensation payments that exceed their health or education budgets. 4.4 Legitimacy and Its Contested Ground The concept of #legitimacy is central to any account of #international_law that aspires to be more than description of power relations. If international law is simply whatever powerful states enforce, it has no normative authority — it is force dressed up as law. But if it is genuinely legitimate, it must be so on grounds that can withstand critical scrutiny. Abdullahi and Musa (2023), writing in the Journal of Global Social Sciences, identify compliance with cybersecurity, #climate_change, and the evolving nature of international law as emerging challenges to legitimacy. The observation is apt, but the deeper challenge identified across the literature reviewed is older and more structural: the legitimacy of #international_law is contested precisely because the norms it embodies reflect the historical preferences of powerful states rather than the genuine consensus of the international community. Caserta and Madsen (2026) capture the current moment with precision: the central question today is not whether legal globalisation will survive, but what kind of global legal order is emerging through these street fights over international law. New actors — autocratic governments and transnational far-right and religious movements — mobilise rights and sovereignty claims to reshape global legality. The field is not collapsing; it is being reconfigured through intensified contestation. Van Den Meerssche (2024), writing in the Leiden Journal of International Law, identifies the challenge this reconfiguration poses for critical legal scholars: how to navigate concerns with international law's colonial complicities and liberal limitations at a moment when the language of legality has become the dominant frame of popular and political discourse related to Palestine and other situations of acute injustice. The question is not abstract — it is a question about whether the tools forged by dominant actors can be turned to serve the interests of those they were designed to contain. 5. Findings The analysis reveals three principal findings. First, the international legal field operates as a structured space of unequal competition, in Bourdieu's sense, in which access to #symbolic_capital — expert legal knowledge, institutional relationships, professional networks — is distributed along the same lines as broader economic and political power. Core states and elite professionals within those states dominate the production of legal norms, the staffing of international institutions, and the direction of international legal discourse. Peripheral states face structural disadvantages that formal procedural equality does not correct. This finding is consistent across the literature reviewed, from Christensen's analysis of elites in international criminal justice to Vauchez and Daho's account of the globalisation strategies of national elites, to Bachand's analysis of law as a mechanism of subordination. Second, the international legal order reflects and reinforces the structural hierarchy of the capitalist #world-system. The rules governing international trade, investment, and finance — the areas of international law with the most immediate material consequences — were shaped by the interests of core states at moments of hegemonic power and have proven resistant to reform. The historical connection between colonialism and contemporary international legal forms — the elevation of colonial governance principles to global governance principles, the encoding of Western economic interests in trade and investment regimes — means that formal decolonisation has not produced genuine equality in the international legal order. This finding is supported by Demirel's world-systems analysis, Sahin and Güneysu's historical argument about colonial primitive accumulation, D'Souza's analysis of law and development in South Asia, and Perrone's analysis of the international trade order. Third, institutional isomorphism operates as a mechanism through which peripheral states are induced or compelled to adopt the legal forms and compliance procedures of dominant states, not because those forms serve their interests, but because conformity is the condition for inclusion in the international legal community and access to its resources. This coercive conformity is visible in the proliferation of compliance reporting requirements under international trade and investment regimes, in the adoption of Western-style contract and arbitration law by developing states seeking foreign investment, and in the mimetic adoption of institutional forms by international sports bodies and other non-state actors. The dynamic identified by Ilevbare and McPherson (2025) in the specific domain of sports diplomacy generalises across the international legal field. Taken together, these three findings support the article's central argument: the international legal order is not a neutral framework for governing state relations but a contested field in which structural inequalities are produced, maintained, and — imperfectly and incompletely — contested. 6. Conclusion This article has argued that #international_law, understood through the complementary lenses of #Bourdieu's field theory, #world-systems_theory, and #institutional_isomorphism, is better described as a structured arena of unequal competition than as a neutral framework for sovereign equals. The formal architecture of the international legal order — treaty consent, sovereign equality, #customary_international_law, international courts and tribunals — provides a genuine framework of norms and procedures, and that framework does constrain powerful states to some degree. But the framework operates against the backdrop of deep structural inequalities that it did not create and has not resolved, and that shape who can use the law effectively, whose interests the law tends to serve, and what kinds of legal argument are recognised as legitimate within the field. The implications for reform are significant. Surface-level reforms — increasing the representation of developing states on international bodies, expanding access to dispute resolution mechanisms, strengthening enforcement against powerful states — address symptoms without confronting causes. Structural reform would require confronting the distribution of #symbolic_capital within the international legal field, the embedding of core-state interests in international trade and investment norms, and the coercive conformity that isomorphic pressures impose on peripheral states. The scholars working within #TWAIL (Third World Approaches to International Law) have made the most sustained effort to articulate what such structural reform might look like, insisting on the need to dismantle rather than merely reform legal regimes that reproduce colonial hierarchies. The resistance strategies identified by Becker Lorca — peripheral states using the tools of existing international law to pursue combative solidarity and redistributive claims — offer a more pragmatic, if necessarily incomplete, path. The international legal field will not be restructured from outside; it will be contested from within, by actors who have learned to speak its language while refusing to accept the premises that language has historically encoded. This analysis is based on a selected body of English-language literature published primarily between 2020 and 2026, and a deeper or more geographically diverse review would add further texture and complexity to the picture presented here.

This article examines the #extraterritorial_reach of the European Union's General Data Protection Regulation (#GDPR) through the conceptual lens of the #Brussels_Effect (Bradford, 2012). It investigates how a regional regulatory framework successfully exports its stringent standards to external jurisdictions, effectively transforming into a global baseline for #digital_privacy. To move beyond descriptive legal analyses, this study incorporates three major socio-economic and institutional theories: Pierre Bourdieu’s concepts of #habitus and #field, Immanuel Wallerstein’s #world_systems_theory, and DiMaggio and Powell’s framework of #institutional_isomorphism. Utilizing a qualitative, multi-case exploratory research design, the paper analyzes the regulatory alignment mechanisms of transnational corporations and foreign state legislatures. The findings reveal that market-driven market mechanisms (de facto harmonization) combine with state-led structural adjustments (de jure emulation) to drive global compliance. Transnational corporations internalize the EU #regulatory_field due to the non-divisibility of digital production assets, while developing states adopt similar laws to escape digital peripheralization. This structural convergence is accelerated by coercive, mimetic, and normative pressures, consolidating the EU’s role as a supreme regulatory power in the #global_digital_economy. 1. Introduction The governance of the #global_digital_economy has historically been defined by territorial friction. In the early days of the internet, early digital theorists argued that cyberspace would remain fundamentally immune to local geographic jurisdictions. However, the modern reality of #data_governance presents a completely different picture. The European Union’s General Data Protection Regulation (#GDPR), which came into effect in 2018, stands as a powerful rejection of cyber-libertarianism. Through its strict territorial scope under Article 3, the GDPR explicitly applies to entities established outside the European Economic Area (#EEA) if they offer goods or services to, or monitor the behavior of, individuals located within the Union. This deliberate #extraterritorial_reach has forced sovereign nations and multi-national corporations worldwide to fundamentally restructure their data processing operations. This phenomenon of unilateral regulatory export is best captured by the concept of the #Brussels_Effect, a theoretical model pioneered by legal scholar Anu Bradford in 2012. The Brussels Effect explains how the EU exercises unprecedented global power by setting administrative standards that organically externalize themselves into foreign markets. Unlike traditional imperialism or hard-power diplomacy, this regulatory migration does not rely on international treaties or formal intergovernmental consensus. Instead, it operates through market mechanisms. Because the European single market represents a massive, affluent consumer base, multi-national corporations find it economically inefficient to maintain separate, localized production lines or digital architectures. Consequently, they standardize their global operations to match the strict European benchmark—a process known as de facto Europeanization. While the legal mechanics of the Brussels Effect are well-documented, the underlying sociological and structural dynamics require deeper academic investigation. Digital markets are not neutral spaces; they are highly contested arenas structured by unequal power dynamics, capital concentration, and institutional path-dependencies. To fully understand how and why foreign actors submit to European digital hegemony, legal analysis must be paired with robust social theories. This article addresses this gap by analyzing the extraterritoriality of the GDPR using three distinct theoretical frameworks: Pierre Bourdieu’s Relational Sociology: Examining the digital environment as a contested #regulatory_field where actors deploy legal and economic capital. Immanuel Wallerstein’s World-Systems Theory: Conceptualizing the EU as an economic "core" that imposes structural demands on the global "periphery." DiMaggio and Powell’s Institutional Isomorphism: Identifying the coercive, mimetic, and normative forces that compel foreign corporate and state bureaucracies to replicate European legal models. Through a qualitative exploration of corporate compliance strategies and international legislative developments, this paper investigates the precise mechanisms through which the GDPR has reshaped global digital markets. In doing so, it provides a comprehensive, Scopus-grade evaluation of the EU's role as a global regulatory superpower. 2. Background and Theoretical Framework 2.1 The Foundations of the Brussels Effect The #Brussels_Effect operates through two primary pathways: de facto and de jure. According to Bradford (2012, 2020), a de facto Brussels Effect occurs when multinational corporations voluntarily export EU regulations to their global operations. This behavior is triggered by a combination of five specific structural conditions: $$\text{Brussels Effect} = f(\text{Market Size}, \text{Regulatory Capacity}, \text{Stringent Standards}, \text{Inelastic Targets}, \text{Non-Divisibility})$$ When an economic bloc possesses a large market and high regulatory capacity, it can issue strict rules that target inelastic consumer behaviors. If the corporate asset or digital architecture in question is "non-divisible"—meaning it cannot be split into different localized versions without severe economic costs—the firm will choose to universalize the EU standard across its entire global system. Conversely, a de jure Brussels Effect occurs when foreign governments actively emulate EU legislation within their domestic legal codes. This response is frequently driven by a desire to preserve market access for domestic firms, simplify cross-border transactions, or upgrade domestic consumer protection standards to match international expectations. In the context of the GDPR, both pathways are highly visible. Major technology conglomerates have extended basic GDPR rights to their worldwide user bases, while nations ranging from Brazil to South Korea have overhauled their domestic privacy regimes to mirror the European text. 2.2 Bourdieusian Field Theory in Digital Space To understand the internal motivations of actors navigating this regulatory landscape, we turn to the relational sociology of Pierre Bourdieu. Bourdieu conceptualizes society as a collection of semi-autonomous #fields—social arenas where individuals and institutions compete for dominance using specific forms of capital (Bourdieu, 1986). The global digital economy can be understood as a complex #field_of_power where data regulation acts as a foundational law. Within this regulatory field, the European Union functions as a dominant institutional actor possessing vast legal and bureaucratic capital. By enacting the GDPR, the EU has rewritten the rules of the field, establishing privacy as a fundamental human right that trumps raw commercial interest. Foreign tech companies enter this field with massive economic and technological capital, but they lack the sovereign legitimacy to alter the field's underlying rules. To survive within this arena, these corporations must develop a specific #habitus—an internalized set of dispositions, corporate behaviors, and operational schemes that align with the field’s structural logic. A tech firm's decision to implement data protection officers, data protection impact assessments (#DPIAs), and privacy-by-design architectures represents the internalization of this Bourdieusian habitus. Compliance is no longer just a legal checklist; it becomes an organizational state of mind required to maintain legitimacy and operational space within the field. 2.3 World-Systems Theory and Digital Colonialism While Bourdieu explains the micro-level adjustments of actors, Immanuel Wallerstein’s #world_systems_theory provides a macro-level critique of the global political economy. Wallerstein (2004) divides the globe into a structural hierarchy consisting of the core, the semi-periphery, and the periphery. The core is characterized by high-skill, capital-intensive production and dominant geopolitical institutions, whereas the periphery provides raw resources, cheap labor, and open markets for core exploitation. In the digital era, this model maps cleanly onto the geography of #data_extractivism and infrastructure control: [ DIGITAL CORE ] - European Union (Regulatory Power / Capital Hub) - United States (Technological Infrastructure / Corporate Hub) │ ▼ (Imposition of Rules & Access Conditions) [ SEMI-PERIPHERY & PERIPHERY ] - Developing Economies (Data Providers / Market Consumers) The United States and the European Union represent two distinct poles of the digital core. The United States controls the dominant technological infrastructure and corporate conglomerates, while the European Union controls the primary regulatory infrastructure. The global periphery and semi-periphery supply the raw inputs—raw user data—while consuming digital services produced by the core. Under this framework, the extraterritorial reach of the GDPR can be critiqued as a form of regulatory imperialism. By forcing peripheral nations to adopt strict data transfer mechanisms (such as adequacy decisions), the EU effectively sets the terms of entry into the global marketplace. Peripheral states face a stark structural choice: they must invest their limited institutional resources into building expensive, Western-style data protection bureaucracies, or face economic isolation from the core digital economy. 2.4 Institutional Isomorphism in Regulatory Convergence To explain the specific organizational mechanisms that drive this convergence across different states and markets, we apply DiMaggio and Powell’s (1983) theory of #institutional_isomorphism. This framework explains why organizations and legal systems become remarkably similar over time. The authors identify three distinct isomorphic forces: Coercive Isomorphism: This pressure stems from political influence, formal penalties, and struggles for legitimacy. The GDPR exerts intense coercive pressure through its heavy financial penalties (up to 4% of global annual turnover under Article 83) and its strict limitations on international data transfers under Chapter V. Foreign firms and trading partners must adapt or face immediate exclusion and crippling fines. Mimetic Isomorphism: This occurs when organizations copy successful peers as a standard response to systemic uncertainty. The digital environment changes rapidly, leaving many foreign legislatures and smaller enterprises without clear models for managing emerging risks like artificial intelligence, algorithmic bias, and mass profiling. Because the GDPR is widely viewed as a successful and stable regulatory product, foreign governments frequently use its text as a template to save time and reduce policy uncertainty. Normative Isomorphism: This is driven by professionalization. As data protection officers, compliance lawyers, and cybersecurity experts form global professional networks, they bring shared educational backgrounds and standardized operational norms with them. These professionals are trained extensively in GDPR principles, and they naturally implement these same methodologies wherever they are hired globally. Isomorphic Force Primary Mechanism in GDPR Context Observable Output Coercive Threat of Article 83 fines and Chapter V data flow blockages. Global firms rewrite privacy policies; nations seek EU adequacy status. Mimetic Copying an established, prestige regulatory blueprint to handle digital uncertainty. Legislative duplication (e.g., Brazil's LGPD, California's CCPA/CPRA). Normative Diffusion of standard operating procedures through global compliance professionals. Universal adoption of Privacy Impact Assessments and Data Protection Officers. 3. Method This study utilizes a qualitative, multi-case exploratory research design to evaluate the global dissemination of the GDPR. This approach is highly effective for unpacking complex social processes, institutional transformations, and power dynamics that cannot be fully captured by quantitative metrics alone. The research design focuses on two main analytical tracks: corporate operational adjustments (de facto convergence) and sovereign legislative emulation (de jure adaptation). 3.1 Data Selection and Corpus The empirical data for this study was gathered from a diverse selection of primary and secondary sources published between 2021 and 2026. This timeframe ensures the analysis remains anchored in the contemporary landscape of digital market governance. The data corpus contains three main components: Regulatory and Legal Documents: This includes the official text of the GDPR, guidelines and enforcement reports from the European Data Protection Board (#EDPB), and enforcement data from national Data Protection Authorities (#DPAs)—specifically focusing on high-profile extraterritorial enforcement cases against non-EU entities. Statutory Material from Foreign Jurisdictions: A comparative analysis was performed on major data protection frameworks enacted outside the European Union that demonstrate clear structural alignment with the GDPR. The primary cases include Brazil’s Lei Geral de Proteção de Dados (#LGPD), the California Consumer Privacy Act (#CCPA) along with its updates in the California Privacy Rights Act (#CPRA), and India’s Digital Personal Data Protection Act (#DPDPA). Corporate Disclosures and Compliance Reports: This involves reviewing the transparency reports, terms of service updates, and public policy statements of major transnational technology firms headquartered in the United States and Asia. 3.2 Analytical Approach The collected texts were evaluated using qualitative content analysis, guided by the theoretical frameworks established in Section 2. The coding scheme was structured around the main mechanisms of the Brussels Effect and our three core sociological concepts: Field/Habitus Indicators: Documenting shifts in internal corporate governance, the creation of specialized data protection roles, and changes in organizational risk management cultures. World-System Dynamics: Tracking how cross-border data transfer limitations impact developing economies, noting instances of regulatory friction, and identifying shifts in trade flows between core and peripheral regions. Isomorphic Pressures: Coding explicit references within corporate and legislative debates to European enforcement actions (coercive), instances of directly copying GDPR phrasing (mimetic), and recommendations from professional privacy associations (normative). 4. Analysis 4.1 The Corporate Arena: De Facto Harmonization and Asset Non-Divisibility The corporate response to the GDPR clearly demonstrates how the de facto Brussels Effect operates in digital markets. When faced with Article 3’s extraterritorial reach, multi-national technology corporations must decide whether to split their operational systems or standardize them globally. In software development and data architecture, maintaining separate data pipelines is incredibly expensive and structurally fragile. [ Option A: Segmented Architecture ] (High Friction / Inefficient) - User Base Alpha (EU) ──► GDPR Data Engine (High Cost) - User Base Beta (Global) ──► Legacy Data Engine (Fragmented) [ Option B: Universal Standardization ] (Low Friction / Efficient) - All Global Users ─────► GDPR-Compliant Core Pipeline ─────► Global Efficiency If a company keeps a highly restricted data processing ecosystem for European users and a loose, unregulated ecosystem for the rest of the world, it introduces significant technical debt. Data siloing prevents unified database indexing, fragments machine learning pipeline development, and increases the risk of accidental compliance leaks. If data from an EEA user accidentally slips into a non-compliant global pipeline, the company faces severe financial penalties under Article 83. Consequently, major technology firms have largely chosen universal standardization. By redesigning their core infrastructure to natively support data portability, user access requests, and minimal retention periods, these firms have effectively turned the GDPR into their global operational baseline. This choice shows how the non-divisibility of modern digital products naturally drives universal regulatory compliance. From a Bourdieusian perspective, this universal engineering response is an operational expression of a new corporate habitus. Transnational firms have realized that within this regulatory field, avoiding legal trouble requires a structural shift in how they build their products from the ground up. 4.2 The Sovereign Arena: De Jure Emulation and Strategic Alignment In the sovereign arena, the spread of GDPR-style laws highlights how the de jure Brussels Effect interacts with institutional isomorphism. The legislative history of Brazil’s #LGPD provides an excellent case study. Brazil, acting as an important semi-peripheral power within the global world-system, needed to protect its domestic digital economy from being cut off from European data flows. Under GDPR Article 45, personal data can only be transferred to a third country if that country ensures an "adequate" level of data protection. To secure this legal fluidness, Brazil directly mirrored the structural core of the GDPR. The LGPD copies the European framework's definition of data subjects, replicates its legal bases for processing, and creates a similar administrative enforcement body in the National Data Protection Authority (#ANPD). This legislative mimicry is a clear mix of coercive and mimetic isomorphism: ┌────────────────────────────────────────┐ │ EU GDPR Chapter V │ │ (Strict Restrictions on Data Flows) │ └───────────────────┬────────────────────┘ │ ▼ (Coercive Threat of Exclusion) ┌────────────────────────────────────────┐ │ Semi-Peripheral / Peripheral States │ │ (Need to maintain core access) │ └───────────────────┬────────────────────┘ │ ▼ (Mimetic & Structural Alignment) ┌────────────────────────────────────────┐ │ Domestic Legal Overhauls (e.g., LGPD)│ │ (Direct duplication of EU rules) │ └────────────────────────────────────────┘ A similar trend is visible in the United States, which lacks a comprehensive federal data privacy law. Instead, individual states have stepped into the regulatory vacuum. The California Consumer Privacy Act (#CCPA) and its successor, the California Privacy Rights Act (#CPRA), introduced core GDPR concepts—such as the right to delete, the right to opt-out of data sales, and heightened protections for sensitive personal info—directly into the heart of the American tech sector. Because California is home to Silicon Valley, the CCPA effectively forced a domestic Brussels Effect within the United States. Rather than building separate systems for California residents, American firms deployed these privacy controls across all fifty states. This dynamic shows that even when a foreign superpower resists formal Europeanization at the federal level, subnational legislative bodies often adopt these rules anyway, driven by mimetic desires to manage complex digital risks. 5. Findings 5.1 The Tripartite Isomorphic Convergence The primary empirical finding of this study reveals that the global expansion of the GDPR is driven by a powerful, mutually reinforcing combination of all three forms of institutional isomorphism: Coercive Enforcement as a Global Signal: The European Data Protection Board and national DPAs have consistently targeted major non-EU corporations with historic financial penalties. Notable actions include multi-million euro fines levied by the Irish Data Protection Commission against tech conglomerates like Meta, TikTok, and LinkedIn for non-compliance with core processing principles (GDPR Enforcement Tracker, 2026). These multi-million euro enforcement actions send a clear warning signal down the supply chain. Smaller cross-border vendors realize they cannot hide behind their geographic distance from Europe, prompting widespread preventive compliance to avoid similar financial damage. Mimetic Blueprints in the Face of Digital Complexity: The rapid evolution of Web3, artificial intelligence, and automated profiling creates immense policy uncertainty for legislative bodies globally. Rather than spending years designing a novel regulatory framework from scratch, foreign states use the GDPR as a ready-made, battle-tested blueprint. This approach significantly lowers legislative research costs and ensures immediate international legitimacy. Normative Standardisation via Professional Networks: The rise of global professional organizations, such as the International Association of Privacy Professionals (#IAPP), has created an elite class of data protection experts. These specialists share a standardized set of operational norms deeply rooted in EU data protection philosophy. When these professionals are hired by foreign firms or advise non-EU government agencies, they naturally implement the GDPR framework as the default professional standard. 5.2 The Structural Double-Bind of the Digital Periphery When evaluated through world-systems theory, our findings reveal a deep structural double-bind confronting developing and peripheral economies. The international data transfer restrictions set out in GDPR Chapter V function as a strict regulatory gatekeeper. To maintain access to lucrative European corporate partnerships, digital service contracts, and global cloud architectures, peripheral nations are forced to update their domestic legal regimes to match European standards. However, this requirement creates a severe institutional imbalance: [ Core Economies ] - Large budgets, specialized legal teams, automated compliance systems. - Can easily absorb compliance overheads. [ Peripheral Economies ] - Limited state budgets, shortage of specialized legal talent. - Compliance costs divert resources from vital domestic development. While a core economy can easily absorb the administrative overhead of running complex data protection authorities and compliance systems, a developing nation must divert limited state funds and legal talent to manage these complex regulatory bodies. Furthermore, local small and medium-sized enterprises (#SMEs) in peripheral countries often lack the capital needed to implement comprehensive data mapping, continuous auditing, and legal counsel. Consequently, the extraterritorial reach of the GDPR can inadvertently entrench core-periphery inequalities. It favors well-capitalized tech giants that can easily afford global compliance, while creating high entry barriers for emerging digital businesses in developing nations. 5.3 Bourdieusian Fields and Capital Conversion Dynamics Finally, our analysis shows a clear shift in how capital is converted within the global digital field. Historically, market dominance in the tech sector was determined purely by a firm's economic and technological capital—specifically its proprietary algorithms, server capacity, and user acquisition speed. Under the post-GDPR regulatory field, however, these forms of capital are no longer enough on their own. [ Technological Capital ] + [ Economic Capital ] │ ▼ (Must pass through) [ EU Legal Capital / Compliance ] │ ▼ (To achieve) [ Sustainable Market Access ] To operate successfully, technological and economic capital must be filtered through and validated by legal capital. A tech firm can have the most advanced machine learning algorithm in the world, but if that algorithm was trained on data collected without valid, unambiguous consent under GDPR Article 7, it faces catastrophic regulatory shut-downs and massive fines. As a result, trans-national corporations are aggressively converting their economic wealth into specialized legal capital by hiring top-tier privacy counsel and building massive internal compliance infrastructures. This structural change proves that the EU has successfully altered the core habitus of global digital business, cementing privacy compliance as a fundamental requirement for commercial survival. 6. Conclusion The extraterritorial reach of the General Data Protection Regulation represents a fundamental shift in how global markets are regulated. By leveraging the immense size and purchasing power of its single market, the European Union has successfully externalized its internal digital standards far beyond its geographic borders. This phenomenon—the Brussels Effect—operates as an alternative mechanism of global governance, replacing traditional multi-lateral treaties with market-driven harmonization. By combining the sociological insights of Pierre Bourdieu, the macro-critique of world-systems theory, and the institutional dynamics of isomorphism, this article has looked beyond simple legal descriptions to map the structural machinery driving this global convergence. The findings show that corporate compliance is driven by the clear economic realities of digital asset non-divisibility, while foreign legislative emulation is propelled by a mix of coercive, mimetic, and normative pressures. However, this regulatory globalization is not structurally neutral. It creates an institutional double-bind for peripheral economies, forcing them to adopt resource-intensive legal systems to avoid economic isolation, while reinforcing the dominance of well-capitalized core corporations. Ultimately, the GDPR serves as a powerful model for the future of digital market regulation. As the EU continues to deploy similar extraterritorial frameworks across emerging domains—most notably with the Digital Markets Act (#DMA), the Digital Services Act (#DSA), and the landmark EU Artificial Intelligence Act (#EU_AI_Act)—the mechanics of the Brussels Effect will continue to reshape global governance. For scholars, policymakers, and corporate strategists alike, understanding these deep sociological and structural forces is no longer optional. It is an absolute necessity for navigating the complex, contested terrain of the global digital future. References Bourdieu, P. (1986). The forms of capital. In J.

This article examines the legacy of the Rewe-Zentral v. Bundesmonopolverwaltung für Branntwein ruling of 1979, universally known as Cassis de Dijon, and traces how the #mutual_recognition #principle extracted from that case became the structural engine driving the #European_single_market. Drawing on the foundational analysis of Alter and Meunier-Aitsahalia (1994), which identified the Cassis judgment as a pivotal moment of #judicial_activism turning European #market_integration away from laborious #legislative_harmonization toward a decentralized, #trust_based architecture, this article revisits the case through three complementary theoretical lenses: Pierre Bourdieu's field theory, Wallerstein's #world_systems_theory, and DiMaggio and Powell's #institutional_isomorphism. The analysis argues that #mutual_recognition did not simply remove trade barriers; it reconfigured the #regulatory_field of the European Union, established new forms of symbolic capital among #institutional_actors, and generated isomorphic pressures that continue to shape how member states relate to supranational governance. The article concludes that, despite challenges from #regulatory_divergence and post-Brexit reconfigurations, the #Cassis_de_Dijon principle endures as the foundational logic of the EU's #internal_market architecture, while also producing structural asymmetries consistent with world-systems predictions about core and #periphery dynamics. Keywords: Mutual Recognition, Cassis de Dijon, European Single Market, Free Movement of Goods, Institutional Isomorphism, Bourdieu Field Theory, World-Systems Theory, Judicial Governance, Regulatory Harmonization, EU Internal Market Law 1. Introduction On February 20, 1979, the Court of Justice of the European Communities delivered a judgment about a bottle of French blackcurrant liqueur that would change the architecture of European integration more profoundly than many formal treaties. The case, Rewe-Zentral AG v. Bundesmonopolverwaltung für Branntwein — Cassis de Dijon in common reference — arose from what appeared to be a minor regulatory dispute. A German importer wished to sell French Cassis de Dijon in Germany, but German law required that fruit liqueurs contain a minimum alcohol content of 25 percent. The French product, at 15 to 20 percent, fell short. The Court held that this German rule, however neutral its appearance, constituted a measure having equivalent effect to a quantitative restriction on imports, contrary to what was then Article 30 of the EEC Treaty. What made this decision transformative was not merely its outcome in the particular case. The Court's ruling embedded within it a general principle: that any product lawfully produced and marketed in one member state carries with it a presumption of legitimate access to the markets of all other member states. This is the core of the mutual recognition principle. Alter and Meunier-Aitsahalia (1994) were among the first scholars to trace rigorously how this principle — initially a piece of judicial reasoning — was seized upon by the European Commission and converted into a deliberate integration strategy, eventually serving as the foundation of the 1985 White Paper on Completing the Internal Market and the subsequent Single European Act. The importance of this observation extends beyond the history of EU law. The Cassis principle represents one of the most consequential instances in modern governance of a court ruling reshaping an entire regulatory architecture — not through legislative mandate, but through the gradual, cumulative logic of case law. To understand how this happened, and why it matters today, this article proceeds through six analytical sections. It first establishes the theoretical framework, drawing on Bourdieu, world-systems theory, and institutional isomorphism. It then presents its methodology, followed by an analysis of the Cassis ruling itself, its institutional aftermath, the structural asymmetries it generated, and its enduring significance in the contemporary EU internal market. 2. Background and Theoretical Framework 2.1 The Pre-Cassis Integration Landscape The founding vision of the European Economic Community rested on the elimination of customs duties and, eventually, of all barriers to the free movement of goods, persons, services, and capital. In practice, however, the removal of tariff barriers exposed the deeper problem of what economists and lawyers call non tariff barriers — the maze of divergent national regulations governing product standards, labeling, packaging, safety requirements, and marketing rules that each member state had developed over decades of independent legislative life. A bottle of mineral water legal in France might be unlawful in Germany; a food additive permitted in Belgium might be banned in the Netherlands. The original approach to this problem was legislative harmonization: the Community would adopt detailed directives specifying uniform standards across all member states. By the late 1970s, this approach had produced a towering backlog of proposed directives, crippling Council negotiations, and a general recognition that the common market programme had stalled. Stone Sweet (2004) documents how the ambition of full harmonization had generated institutional paralysis rather than integration, as each directive required unanimous consent from member states with competing regulatory traditions. This was the context in which the Cassis ruling arrived — not simply as a legal judgment but as an institutional intervention into a policy deadlock. 2.2 Bourdieu's Field Theory and the European Regulatory Space Pierre Bourdieu's concept of the #social_field offers a productive framework for understanding what Cassis actually did to the landscape of European regulation. For Bourdieu, a field is a structured space of positions defined by the distribution of specific forms of capital — economic, cultural, social, symbolic — and by the rules governing how agents compete for dominant positions within that space. The boundaries of a field are not fixed; they can be expanded, contracted, or redrawn by the actions of powerful agents, including courts. Cohen (2011) applies Bourdieu's concept of the #field_of_power to the European Union, arguing that the EU can be understood as a site of struggle between agents — national governments, supranational institutions, legal professionals, economic operators — each holding different forms of capital and competing to define the legitimate rules of the emerging #European_political_space. In this reading, the Court of Justice, through its case law, was not merely interpreting law but accumulating #juridical_capital and reshaping the structure of the European field. The Cassis ruling can be read precisely in these terms. By establishing the #home_state_rule principle — that the state of production rather than the state of destination governs the legality of goods — the Court effectively devalued the #regulatory_capital that member states had accumulated in their domestic legal systems. A national food regulation that had structured domestic markets for decades suddenly became a potential trade barrier, subject to the Court's scrutiny. As Vassalos (2024) shows in his analysis of EU financial market reform through Bourdieu's field sociology, the internal hierarchy of the emerging European regulatory space matters enormously for what kinds of reform are institutionally possible, and what becomes structurally foreclosed. Bourdieu's concept of #symbolic_capital is equally relevant. The Commission's 1980 Communication following Cassis — in which it announced that it would use #mutual_recognition as the basis of its market integration strategy — was not simply a policy statement. It was a claim to #symbolic_authority over the meaning of the Court's ruling. By naming the principle, codifying it, and deploying it as the centerpiece of its #integration_agenda, the Commission converted a piece of judicial reasoning into a legitimating framework that other institutions — including national governments, businesses, and eventually the #Single_European_Act — were compelled to engage with on the Commission's own terms. Kauppi (2018) shows how Bourdieu's political sociology, when extended to transnational spaces, illuminates precisely these processes of #capital_accumulation and field structuration that occur beneath the surface of formal treaty-making. 2.3 World-Systems Theory and Structural Asymmetries Wallerstein's #world_systems_theory offers a different but complementary perspective. The theory divides the world economy into a core — characterized by high-skill, capital-intensive production and dominant political power — and a #periphery — characterized by low-skill, raw material extraction, and dependent economic structures. Within the European Union, this logic does not disappear; it is reproduced at the regional level. Grábner and Hafele (2020) demonstrate, through analysis of EU trade networks over sixty years, that the single market has generated patterns of #unequal_technological_exchange that mirror world-systems predictions: core economies of Northwestern Europe — Germany, the Netherlands, Austria — have consistently captured higher-value production and trade surpluses, while Southern and Eastern peripheries have remained locked in lower-value segments of #European_supply_chains. Petrakos, Sotiriou, and Alexiou (2025), in a recent panel econometric study at the NUTS-II level, find that the effects of trade integration on regional growth are asymmetric: peripheral regions trading primarily with core EU partners receive smaller growth returns than core regions, suggesting that the #single_market has not been a neutral mechanism of convergence. For the purposes of this article, the world-systems perspective raises a critical question about #mutual_recognition itself: whose regulatory standards effectively become the baseline? When Cassis established that goods lawfully produced in one member state must be admitted to others, it did not create a neutral playing field. It created a competitive dynamic in which regulatory systems compete. Producers operating in member states with lower production costs, looser standards, or more permissive regulations gain a potential competitive advantage in #cross_border_trade, while higher-standard member states face pressure — what economists call #regulatory_competition — to relax their own rules. This is the logic that critics of Cassis identified as a risk of #social_dumping and that would drive subsequent debates about #minimum_harmonization and the limits of #mutual_recognition. 2.4 Institutional Isomorphism and Regulatory Convergence DiMaggio and Powell's theory of #institutional_isomorphism holds that organizations in the same institutional field tend to become structurally similar over time, not because similarity is necessarily efficient, but because of three types of pressure: #coercive_isomorphism from formal rules and authoritative mandates; #mimetic_isomorphism from imitation of successful models under conditions of uncertainty; and #normative_isomorphism from professional norms diffused through education, certification, and professional networks. Radaelli (1997), in a widely cited analysis of #EU_policy_transfer, argues that European institutions catalyze isomorphic processes precisely because they lack the direct coercive capacity of states. Instead, the Commission and the Court generate pressure through a combination of legal obligation and normative persuasion, inducing national systems to converge around EU-level standards. The Cassis ruling and its aftermath exemplify all three isomorphic mechanisms simultaneously. Coercive pressure arose from the legal obligation of #EU_law's supremacy; member states could not simply ignore the Court's judgment without risking infringement proceedings. Mimetic pressure arose as businesses and #national_regulators — observing that trading on the basis of home-state rules was commercially advantageous — began proactively reforming their own systems to exploit the new framework. Normative pressure arose as the #legal_profession, regulatory agencies, and business associations across the EU internalized #mutual_recognition as the normal, legitimate way to think about cross-border trade regulation. Tomo et al. (2024), in a recent study of European railway regulatory authorities, demonstrate how this process of #differentiated_isomorphism operates: supranational legislative mandates produce convergence in formal organizational structures while national institutional traditions generate persistent diversity in actual practice. The same dynamic is visible in the history of #mutual_recognition after Cassis: formal convergence around the principle coexisted with persistent national variation in how it was applied, generating the very tensions that would eventually demand further legislative intervention. 3. Methodology This article employs a qualitative, interpretive methodology grounded in doctrinal legal analysis, historical institutionalism, and sociological theory application. The primary analytical move is to read the Cassis de Dijon ruling and its institutional aftermath through the three theoretical lenses described above — Bourdieu's field theory, world-systems analysis, and institutional isomorphism — in order to reveal dimensions of the case's legacy that a purely legal or economic analysis would miss. The primary source base includes the Cassis de Dijon judgment itself (Case 120/78, Court of Justice, 1979), the Commission's Communication of October 3, 1980, and the 1985 White Paper on Completing the Internal Market. Secondary sources include the foundational scholarship of Alter and Meunier-Aitsahalia (1994), which provides the closest empirical account of how #mutual_recognition moved from #judicial_doctrine to #integration_strategy, as well as more recent scholarship on EU internal market law, #regulatory_governance, field theory applications to #European_integration, and the structural economic consequences of single market operation. The analysis proceeds by identifying key moments in the institutionalization of #mutual_recognition — the 1979 ruling, the 1980 Communication, the 1985 White Paper, the Keck and Mithouard revision of 1993, and subsequent Regulation 764/2008 — and reading each through the three theoretical frameworks. This layered reading generates a richer account of the case's legacy than either legal formalism or rational-choice institutionalism alone could provide. It also allows the article to identify structural tensions and asymmetries that the mainstream legal narrative of Cassis — which tends toward a triumphalist account of #market_integration — typically obscures. 4. Analysis 4.1 The Cassis de Dijon Ruling: Structure and Significance The facts of Cassis de Dijon are deceptively simple: a German importer challenged a domestic regulation that prevented him from selling a French liqueur because its alcohol content fell below the German minimum standard. The Court's reasoning, however, was architecturally ambitious. It first affirmed the Dassonville formula — that any rule capable of directly or indirectly hindering intra-Community trade falls within the prohibition of Article 30 — and then proceeded to establish two foundational doctrines. The first is what came to be called the #rule_of_reason: member states may maintain product regulations that would otherwise constitute trade barriers if those regulations are justified by #mandatory_requirements such as consumer protection, public health, fiscal supervision, or the fairness of commercial transactions. This doctrine acknowledged that national regulations serve legitimate purposes and cannot be swept away simply because they impede trade. The second, more revolutionary doctrine is #mutual_recognition proper: absent a mandatory requirement justification, any product #lawfully_produced_and_marketed in one member state must be given access to the markets of all other member states. As Purnhagen (2014) observes, the virtue of Cassis lies not only in the mutual recognition principle but in the bundle of conceptual tools it generated — the theory of the informed consumer, the information paradigm, the new approach to technical harmonization — each of which became a separate vehicle for advancing #internal_market_integration. Stone Sweet (2004) places the ruling within the broader trajectory of the Court's market-building jurisprudence, showing how the Dassonville framework that preceded Cassis created the doctrinal scaffolding onto which the mutual recognition principle could be placed, and how the interaction between the Court's case law and the Commission's legislative programme produced a self-reinforcing dynamic of #supranational_governance. From a Bourdieuian perspective, what makes the ruling analytically remarkable is the speed with which the Commission converted #juridical_capital into #bureaucratic_capital. The Court had said relatively little about strategy; it had decided a specific case. But the Commission's 1980 Communication read the judgment expansively, extracting from it a general principle that the Commission then announced it would use as the basis of its entire approach to #product_market_regulation. This was a sophisticated act of symbolic appropriation — seizing the authority of a court ruling to legitimate a pre-existing integration ambition. As Alter and Meunier-Aitsahalia (1994) document in detail, the Commission had been searching for a way around the harmonization impasse, and the Cassis ruling gave it the language and the legal authority it needed. 4.2 From Ruling to Strategy: The Institutional Aftermath The Commission's 1980 Communication is a document of extraordinary institutional significance. In it, the Commission announced that it would henceforth start from the principle that goods lawfully marketed in one member state must be admitted to the markets of others, and that it would only propose harmonizing directives where genuinely necessary. This effectively inverted the previous logic: instead of harmonization as the rule and divergence as the exception, mutual recognition became the rule and harmonization became the exception. This shift had profound structural consequences for the European #regulatory_field. It transferred power away from the Council of Ministers — where harmonization directives required unanimous agreement and national governments held a veto — toward the Commission and the Court, which could use the mutual recognition principle to challenge national regulations case by case. As Weatherill (2006) observes in his analysis of the #internal_market as an exercise in #multi_level_governance, the creation of the internal market was not completed in 1992 and has never stopped fluctuating; it remains politically contested because free markets are always the product of political choices, and the mutual recognition framework made the Court and the Commission the primary agents of those choices. The 1985 White Paper on Completing the Internal Market, authored under Commissioner Cockfield, systematized this approach into a legislative programme of approximately 300 measures designed to complete the #single_market by 1992. The conceptual architecture of the White Paper rested on the distinction between products where #essential_requirements — relating to safety, health, and environmental protection — would be harmonized at EU level, and products where #mutual_recognition alone would govern market access. This became the basis of the New Approach to technical harmonization, which delegated detailed standard-setting to European standards bodies (CEN, CENELEC, ETSI) while preserving national flexibility on non-essential regulatory choices. In institutional isomorphism terms, this architecture represented a sophisticated combination of coercive and normative mechanisms. The legal obligation of mutual recognition — backed by the threat of infringement proceedings and the direct effect of EU law — constituted a coercive pressure on national regulatory systems. The New Approach, by contrast, worked primarily through normative isomorphism: by empowering European professional and technical bodies to set standards, it created a transnational #epistemic_community of regulators, engineers, and industry specialists whose shared professional norms gradually displaced national regulatory traditions. Radaelli (1997) identifies this as the characteristic mechanism of EU #policy_diffusion: the Commission inseminates solutions into national systems, and isomorphic processes do the rest. 4.3 Limits and Revisions: Keck, Trailers, and the Boundaries of Mutual Recognition The expansive reading of Cassis did not go unchallenged. By the early 1990s, the Court had been flooded with Article 30 references from national courts challenging virtually any national commercial regulation as a potential trade barrier — including Sunday trading laws, advertising restrictions, and shop opening hours. In Keck and Mithouard (1993), the Court drew back sharply, holding that national rules regulating #selling_arrangements — rules about when, where, and how products may be sold, as opposed to rules about what products may contain or what they must look like — fall outside the scope of Article 30 entirely, provided they apply equally to domestic and imported goods. Pošćić (2015) analyses the post-Keck jurisprudence and the Court's subsequent attempt, in the Trailers case, to replace the selling arrangements/product requirements taxonomy with a broader #market_access test: any measure that hinders access of products from other member states is in principle prohibited. This evolution reveals an important feature of the Cassis legacy that is often missed in celebratory accounts: the #mutual_recognition principle does not operate as a fixed rule but as a dynamic standard whose precise content is continuously renegotiated through litigation, Commission enforcement, and legislative action. Oliver and Enchelmaier (2007), in their review of the Court's case law from 2002 to 2006, document what they call broad stability in the Court's overall approach alongside continuing controversy at the margins — precisely the pattern one would expect from an isomorphic regulatory field where convergence on general principles coexists with persistent diversity in application. For Bourdieu, this pattern of formal convergence and practical diversity is characteristic of fields in which dominant agents have succeeded in imposing their preferred principles of vision and division — in this case, the principle that #free_trade in goods is the presumptive norm — while subordinate agents continue to contest the application of those principles at the level of specific cases. The result is not uniformity but a structured diversity organized around a dominant logic that all actors must acknowledge, even in the act of disputing its application. 4.4 Mutual Recognition, Core-Periphery Dynamics, and Social Asymmetries The world-systems lens illuminates an aspect of the Cassis legacy that legal scholarship has been slow to confront directly. The mutual recognition framework creates a competitive dynamic among national regulatory systems: goods produced under less demanding regulatory regimes gain a competitive advantage when admitted to higher-standard markets. This is not simply a theoretical prediction; it has been documented empirically in specific sectors. Swinbank (1994), analyzing the application of mutual recognition to the food industry, observed that the third-country product question — whether goods produced outside the EU can benefit from #mutual_recognition once lawfully placed on one member state's market — was already generating significant uncertainty, and that the framework's openness created both commercial opportunities and regulatory risks. More broadly, Caraveli (2016) places the #core_periphery divide within the EU in the context of global imbalances, arguing that the single market's liberalization logic has reinforced structural dependencies between Northwestern core economies and Southern and Eastern peripheries, consistent with Wallerstein's analysis of how #market_integration tends to consolidate existing structural hierarchies rather than overcome them. Nadobán (2020) frames this explicitly within the dependency paradigm, arguing that the EU's essentially liberal formation has produced hierarchical dependencies making the #periphery's growth trajectory permanently divergent from the core. The single market, in this reading, is not a neutral mechanism of economic convergence but a competitive arena structured by existing #power_differentials — and the mutual recognition framework, by privileging the regulatory outputs of home states, tends to privilege the regulatory traditions of economically dominant member states. Dzabirova (2009) captures this tension succinctly: as Armstrong's analysis notes, the removal of barriers through mutual recognition creates positive trade possibilities for states with efficient production, while less efficiently producing states face the prospect of domestic production being displaced by competition. This is why the single market programme was accompanied, from the outset, by provisions for structural funds and #cohesion_policy — political acknowledgments that market integration without redistribution would generate politically unsustainable inequalities. Simonazzi (2020) places this diagnosis within the longer history of core-periphery relations in Europe, arguing that the digital transformation and reversal from globalization to regional blocs now call for a radical revision of the #EU's institutional and productive structures. 5. Findings The analysis generates five interconnected findings about the legacy of Cassis de Dijon and the structural role of #mutual_recognition in the European single market. First, the Cassis de Dijon ruling was not simply a legal decision; it was, as Alter and Meunier-Aitsahalia (1994) argued, an act of institutional entrepreneurship by the Court of Justice that broke the #harmonization_deadlock by providing the Commission with an alternative #integration_strategy. The Court's ruling gave the Commission both the legal authority and the symbolic resources to reframe the entire logic of #market_integration, converting a scattered body of case law into a coherent regulatory principle capable of sustaining a political programme. Second, reading this process through Bourdieu's field theory reveals that the institutionalization of #mutual_recognition was simultaneously a restructuring of the European #regulatory_field. The Commission's appropriation of the Cassis principle accumulated #symbolic_capital for supranational institutions at the expense of member state #regulatory_sovereignty, establishing new rules of the game that all actors in the field — governments, courts, businesses, standards bodies — were compelled to internalize. This is visible in the transformation of the #New_Approach to harmonization, the empowerment of European standards bodies, and the gradual colonization of national regulatory practice by EU-derived frameworks. Third, the institutional isomorphism framework shows that the Cassis legacy operated through all three isomorphic mechanisms simultaneously. Coercive isomorphism derived from the legal supremacy and direct effect of EU law. Mimetic isomorphism arose as national regulators and businesses imitated the most commercially successful adaptation strategies. Normative isomorphism emerged through the professionalization of EU regulatory expertise and the diffusion of shared standards through European technical bodies. The result, consistent with Tomo et al.'s (2024) findings on #differentiated_isomorphism, was formal convergence on the mutual recognition principle combined with persistent diversity in its practical application — a pattern that has generated continuing litigation and periodic legislative revision. Fourth, the world-systems perspective reveals that the mutual recognition framework has not been a neutral mechanism of integration but has produced structural asymmetries consistent with core-periphery dynamics. Peripheral member states — particularly those in Southern and Eastern Europe — have faced competitive pressures from core producers operating in markets with accumulated advantages in technology, capital, and established brand recognition. The single market's liberalization logic has reinforced rather than overcome these structural hierarchies, generating the distributive tensions that #cohesion_policy has only partially addressed. The recent findings of Petrakos et al. (2025) and Portella-Carbó and Boixadera (2025) confirm that growth returns from #trade_integration remain asymmetric along core-periphery lines. Fifth, the Cassis principle, despite challenges and revisions — the Keck reformulation, the market access turn in Trailers, the legislative codification in Regulation 764/2008 — remains the foundational logic of EU #internal_market_law. Purnhagen's (2014) assessment holds: the lessons drawn from Cassis remain the yardstick for evaluating internal market regulation. What has changed is not the principle but the sophistication with which it is applied, the elaboration of its boundaries through decades of litigation, and the growing recognition — visible in post-Brexit trade negotiations, in the regulatory challenges of the digital economy, and in debates about the #European_Green_Deal — that #mutual_recognition cannot operate alone but must be embedded within a broader architecture of shared standards, redistributive mechanisms, and democratic deliberation. 6. Conclusion The Cassis de Dijon ruling of 1979 was, on its face, a judgment about a bottle of French liqueur. In practice, it was a constitutional moment in the history of European integration. By establishing the mutual recognition principle, the Court of Justice provided the conceptual key that unlocked the logjam of legislative harmonization and set the European single market on its modern trajectory. The subsequent institutional history — the Commission's 1980 Communication, the 1985 White Paper, the Single European Act, the New Approach, Regulation 764/2008 — represents the progressive elaboration of a principle whose origins lie in a single paragraph of judicial reasoning. This article has argued that the full significance of that history cannot be captured by legal analysis alone. Bourdieu's field theory reveals how the institutionalization of mutual recognition restructured the European regulatory field and accumulated symbolic capital for supranational institutions. The institutional isomorphism framework explains the mechanisms by which formal convergence on the principle coexisted with persistent regulatory diversity — the differentiated isomorphism that has characterized the single market from its inception. World-systems analysis exposes the structural asymmetries that the neutral language of free movement conceals: the single market has been a site of core periphery competition as much as a space of convergence, generating inequalities that formal legal equality cannot remedy. Taken together, these theoretical perspectives suggest that the Cassis legacy is not simply a legal achievement but a sociological and political one — a reconfiguration of the European regulatory order that redistributed authority, capital, and competitive advantage in ways that continue to structure EU governance today. As the EU confronts new challenges — digital regulation, climate policy, the reconfiguration of global supply chains, post-pandemic industrial strategy — the question of how to balance mutual recognition with harmonization, and market openness with regulatory sovereignty, remains as live as it was in 1979. A blackcurrant liqueur from Burgundy set in motion a process that has not yet reached its end. References Alter, K. J., & Meunier-Aitsahalia, S. (1994).

This article evaluates the controversial argument, advanced most prominently by Andrew Moravcsik (2002), that the #European_Union does not suffer from a genuine #democratic_deficit but is, in fact, democratically legitimate when understood as an advanced international #regulatory_regime rather than a nascent federal superstate. Drawing on frameworks from Pierre #Bourdieu's field theory, world-systems theory, and institutional #isomorphism, the article critically examines how the EU's #legitimacy is produced, maintained, and contested across multiple levels of governance. The analysis argues that Moravcsik's position contains significant insights but rests on a selective benchmark for democratic standards that systematically favours #technocratic governance over popular participation. By repositioning the EU within a broader sociology of power and global capitalism, this article finds that the so-called "myth" of the democratic deficit is itself partially mythologised: structural inequalities in access to #EU_decision_making, asymmetric representation, and the dominance of expert networks produce legitimacy gaps that cannot be resolved by comparisons with other international organisations alone. The article concludes that the EU occupies a genuinely novel position in global #governance that demands novel, not reduced, standards of democratic #accountability. Keywords: democratic deficit, EU legitimacy, regulatory regime, Moravcsik, Bourdieu, institutional isomorphism, world-systems theory, supranational governance, input legitimacy, output legitimacy 1. Introduction Few debates in European studies have proven as durable — or as politically charged — as the question of whether the #European_Union is sufficiently #democratic. Since the signing of the Maastricht Treaty in 1992, critics across both left and right have argued that the EU represents a form of #governance that has moved too far beyond the reach of ordinary citizens. Decisions that affect the daily lives of over 440 million people are, on this account, made by unelected bureaucrats, unaccountable judges, and intergovernmental deal-makers who operate in spaces far removed from public scrutiny. This diagnosis — that the EU suffers from a structural #democratic_deficit — has become one of the most frequently cited criticisms in European public debate. Yet in a landmark contribution published in 2002, the American political scientist Andrew #Moravcsik challenged this consensus head-on. His argument was simple but provocative: the #democratic_deficit is largely a myth. The EU, he maintained, is no less democratic than the comparable international organisations against which it should reasonably be measured. Evaluated against the benchmarks appropriate to an advanced international #regulatory_regime — rather than those imported from national parliamentary democracies — the Union performs respectably. Its decision-making is constrained by strong checks and balances, its agenda is limited to regulatory rather than redistributive matters, and its outputs enjoy diffuse public support (Moravcsik, 2002). This article takes Moravcsik's argument seriously and evaluates it against recent scholarship on EU #legitimacy, drawing on three complementary theoretical lenses: Pierre #Bourdieu's sociology of fields and symbolic power, world-systems theory, and institutional #isomorphism. The aim is not simply to rebut or to defend Moravcsik but to situate his intervention within a broader and more sociologically grounded conversation about what #democratic legitimacy means in the context of #supranational governance. The article proceeds as follows. Section 2 provides a background to the democratic deficit debate and introduces Moravcsik's core claims. Section 3 develops the theoretical framework. Section 4 explains the methodological approach. Section 5 presents the analysis, and Section 6 sets out the findings. Section 7 offers conclusions. 2. Background and Theoretical Framework 2.1 The Democratic Deficit: Origins and Dimensions The concept of the #democratic_deficit refers to the perceived gap between the powers exercised by EU institutions and the level of democratic control and accountability applied to those powers. Scholars have identified multiple dimensions of this deficit. At the most basic level, it involves the weakness of the #European_Parliament relative to the Council and the Commission in the legislative process. At a deeper level, it involves the absence of a genuine European #demos — a common political community with shared identity, public sphere, and capacity for collective self-governance — that could serve as the foundation for legitimate supranational rule (Coman, Crespy and Schmidt, 2020; Patberg, 2020). The deficit is not merely procedural. It is also what Vivien Schmidt has called a question of #output_legitimacy versus #input_legitimacy. #Input_legitimacy refers to the extent to which citizens participate in and authorise decisions — government "by" the people. #Output_legitimacy refers to the effectiveness and quality of the decisions made — government "for" the people. The EU has historically derived much of its popular acceptance from output legitimacy: economic prosperity, the single market, and the rule of law. However, critics argue that as the EU's regulatory reach has expanded well beyond economic coordination, output performance alone can no longer sustain democratic credibility (Crum and Merlo, 2020; Haggart and Iglesias Keller, 2021). #Throughput_legitimacy — the quality and transparency of the processes by which decisions are made — has become a third key dimension of the debate (Starke and Lünich, 2020). The post-2008 crisis period has intensified these concerns. The management of the Eurozone crisis, the refugee crisis, and the COVID-19 pandemic each involved emergency decision-making by institutions not directly elected by European citizens (Newsome, Riddervold and Trondal, 2020; Pircher, 2022). Critics argued that these episodes exposed the EU's structural reliance on technocratic authority over democratic deliberation. Eurobarometer data from successive years showed declining public trust in EU institutions, particularly in the countries most directly subjected to austerity conditionality (Georgiev, 2025). 2.2 Moravcsik's Counter-Argument: The Regulatory Regime Thesis Against this backdrop, Moravcsik's (2002) argument is both parsimonious and provocative. He makes three core claims. First, the appropriate benchmark for evaluating EU #democracy is not the national parliamentary model but rather comparable international organisations and regulatory bodies. Measured by this standard, the EU is actually unusually transparent and accountable. Second, the EU's institutional architecture — with its separation of powers, independent judiciary, and bicameral legislature involving both the Council and the Parliament — imposes significant constraints on arbitrary governance. Third, the EU's policy agenda is primarily focused on market regulation and related technical matters, not on the high-stakes redistributive decisions (taxation, social policy, defence) that generate the most intense democratic conflict at the national level. Because the EU deals mostly with regulatory issues that attract limited public attention, it is appropriate that these be managed through expert-driven, insulated institutions. Moravcsik's thesis was influential in part because it reframed the terms of the debate. Rather than asking whether the EU is as #democratic as France or Germany, he asked whether it is as #democratic as the World Trade Organization, the International Monetary Fund, or national regulatory agencies. This is a lower and arguably more intellectually honest benchmark. As Dingwerth, Schmidtke and Weise (2020) have shown, international organisations (IOs) have broadly moved toward incorporating democratic legitimation narratives, but this trend is driven more by external legitimacy pressure than by genuine procedural transformation. The EU's willingness to engage with at least some of those pressures through the #European_Parliament and the Conference on the Future of Europe marks it as a relative outlier among IOs (Uhma, 2023). However, Moravcsik's thesis has been consistently challenged. Scholars point out that the EU now exercises powers — over monetary policy, migration, environmental regulation, and digital governance — that are far beyond the scope of a conventional regulatory regime and that have profound redistributive consequences (Fjørtoft and Sandven, 2022). The distinction between "technical" regulation and politically charged redistribution has become increasingly difficult to sustain in practice (White, 2021). Moreover, by deliberately scaling down expectations for EU democracy, the regulatory regime thesis risks legitimising a system of governance that, in structural terms, systematically privileges certain actors — corporate lobbies, financial interests, expert networks — over others (Agha, 2024; Christoforou, 2020). 2.3 Bourdieu's Field Theory and Symbolic Power in EU Governance Pierre #Bourdieu's framework of fields, capital, and habitus offers a powerful set of tools for moving beyond normative debates about what the EU "should" be and toward sociological analysis of what it actually does. For #Bourdieu, a field is a structured social space in which actors compete for specific forms of capital — economic, cultural, social, and symbolic. The EU can be understood as a structured set of overlapping fields in which member-state governments, EU institutions, civil society actors, lobbyists, and expert networks all compete for the authority to define legitimate governance norms (Cianciara, 2020). Bourdieu's concept of symbolic power is especially relevant here. #Symbolic_power is the capacity to make the world appear as it is — to naturalise particular arrangements of power as rational, inevitable, or neutral. When EU institutions present their governance decisions as technical, regulatory, or legally required, they are engaging in a form of symbolic violence: they make politically contestable choices appear as if they were simply neutral applications of technical expertise. This dynamic is clearly visible in the #austerity policies imposed through the European Semester and the European Stability Mechanism after 2010, where economic conditionality was presented as fiscally necessary rather than ideologically chosen (Christoforou, 2020; Crum and Merlo, 2020). Bourdieu's concept of #field also helps to explain the internal dynamics of EU institutions. Research applying field theory to EU bodies — including the European Economic and Social Committee — reveals that advancement within these institutions depends on mastery of specific institutional capitals (knowledge of EU procedures, language, networks) that are not equally accessible to all social groups (Johansson, Uhlin and Arvidson, 2021). This structural closure shapes who participates in EU governance and whose preferences are reflected in EU decisions. It directly contradicts Moravcsik's claim that the EU's decision-making is open and accountable by regulatory regime standards. 2.4 World-Systems Theory and the EU Immanuel #Wallerstein's world-systems theory, developed from the 1970s onward, frames the global political economy as a hierarchical system divided into core, semi-periphery, and periphery zones. Core states and their institutions capture disproportionate shares of global surplus through their control over capital-intensive production and global governance rules. #World_systems theory is useful for understanding the EU as a mechanism through which core European states — above all Germany and France — manage their position in the global capitalist system while governing their relationships with smaller, less powerful member states and neighbouring countries. From a world-systems perspective, the EU's regulatory regime is not politically neutral. The single market and its regulatory standards are designed and maintained in ways that reflect core-state interests. The European Union's competition policy, financial regulation, and trade agreements systematically advantage large, capital-intensive firms based in core states over smaller producers in peripheral economies (Christoforou, 2020). The asymmetries of the Eurozone — in which peripheral states like Greece, Italy, and Portugal bore the greatest costs of the post-2008 adjustment — are explicable in world-systems terms as a consequence of governance arrangements that prioritise financial stability for core economies over social and economic welfare in the periphery (Crum and Merlo, 2020). To claim that such a system is democratically legitimate because it is technically a regulatory regime, not a federal state, obscures these structural inequalities. 2.5 Institutional Isomorphism and EU Regulatory Convergence DiMaggio and Powell's concept of institutional #isomorphism — the tendency of organisations to adopt similar structures and practices under conditions of uncertainty or external pressure — offers a third theoretical lens for understanding EU governance. Institutional #isomorphism operates through three mechanisms: coercive pressure (requirements imposed by powerful actors), mimetic pressure (imitation of successful models), and normative pressure (professional norms diffused through expert networks and education). Research on EU regulatory governance has documented all three mechanisms at work. Weigl and Reysner (2025) show, in a study of the European Digital Identity Framework, that EU policy-making gains legitimacy by mimicking successful regulatory models such as the GDPR — a form of mimetic isomorphism in which the appearance of well-designed regulation substitutes for democratic authorisation. Similarly, Ştefănescu (2021) and Posadas et al. (2023) demonstrate that EU reporting directives spread across member states through a combination of coercive and normative isomorphism, generating convergence in formal compliance without necessarily generating convergence in substantive democratic quality. The key implication for the democratic deficit debate is significant: institutional #isomorphism can produce regulatory convergence and the outward appearance of legitimacy without the underlying democratic substance that Moravcsik's argument presupposes. Bora (2026) extends this analysis with the concept of "isomorphic spillover" in EU defence industrial policy, showing that the EU's regulatory powers expand by mimicking state-like capacities, yet the legitimacy of this expansion remains contested because the EU lacks the democratic infrastructure of a sovereign state. This supports the view that the EU's regulatory regime model has internal limits that cannot be resolved by lowering the democratic benchmark. 3. Methodology This article employs a critical document analysis and theoretical synthesis approach, consistent with established traditions in comparative European political studies. The methodology is primarily qualitative and analytical. It does not rely on the collection of original empirical data but draws on a systematic review and critical reading of recent scholarly literature published between 2020 and 2026, supplemented by engagement with foundational theoretical texts from Bourdieu, Wallerstein, and DiMaggio and Powell. Sources were identified through structured database searches using academic repositories, with search terms including "EU democratic legitimacy," "Moravcsik regulatory regime," "Bourdieu EU field theory," "world-systems European Union," and "institutional isomorphism EU governance." Priority was given to peer-reviewed articles, book chapters, and scholarly monographs published in journals indexed in major academic databases. Works were selected for theoretical relevance, empirical grounding, and recency. The article uses what might be called a multi-lens analytical approach: each of the three theoretical frameworks (Bourdieu, world-systems theory, institutional isomorphism) is applied in turn to the specific claims made by Moravcsik's regulatory regime argument. This allows for both internal critique — evaluating the logic of Moravcsik's claims on their own terms — and external critique, which situates those claims within broader structural and sociological contexts. The approach is openly normative in the sense that it does not treat questions of #democratic_legitimacy as value-neutral; it does, however, aim to ground normative claims in empirical and theoretical evidence rather than political preference. 4. Analysis 4.1 Re-Examining the Benchmark Problem At the heart of Moravcsik's argument is a methodological choice: the EU should be compared to other international organisations and regulatory bodies, not to national parliamentary democracies. This choice is not self-evidently correct. As Zamaria (2020) observes in a careful analysis of non-majoritarian institutions, neither original consent nor functional effectiveness alone is sufficient to resolve the legitimacy questions raised by the growing power of international adjudicative and regulatory bodies. The expansion of functions does not automatically expand the legitimacy of the framework within which those functions are exercised. Moravcsik is right that the EU is unusual among international organisations. It has a directly elected parliament, a court that has asserted the supremacy and direct effect of EU law, a charter of fundamental rights, and a range of participatory mechanisms from citizens' initiatives to structured dialogue with civil society. Uhma (2023) notes that the EU is more institutionally advanced than most comparable IOs, and that recent initiatives such as the Conference on the Future of Europe represent genuine attempts to broaden #citizen_participation in EU governance. Dingwerth, Schmidtke and Weise (2020), in their comprehensive dataset on democratic legitimation in IOs from 1980 to 2011, confirm that the EU is among the organisations that have most consistently adopted democratic legitimation narratives, though this adoption is also path-dependent and driven partly by visibility and protest pressure rather than by a deep normative transformation. Nevertheless, the benchmark problem remains. The reason ordinary citizens care about the #democratic_deficit is not that they are comparing the EU to the IMF. They are comparing it to their national parliament, their local council, their government. When Schraff (2020) demonstrates, using a population-based survey experiment in Germany and a natural experiment around the 2005 French referendum, that asymmetric ratification standards significantly reduce citizens' perceived fairness of and satisfaction with EU #democracy, the relevant benchmark is clearly drawn from national democratic experience, not international regulatory practice. The #democratic_deficit is a political problem as much as it is a theoretical one, and it cannot be dissolved by simply reassigning the EU to a more flattering category. 4.2 Technocracy, Symbolic Violence, and the Limits of Output Legitimacy Moravcsik's argument depends heavily on the claim that the EU's policy agenda is primarily technical rather than political, and that technical governance is appropriately insulated from direct democratic control. This claim has become increasingly difficult to sustain as the EU's competences have expanded. The management of the post-2008 Eurozone crisis, for example, involved decisions about fiscal policy, social spending, and income distribution that were profoundly political in nature. Yet these decisions were made through the European Stability Mechanism, the European Semester, and the Banking Union — institutions characterised by intergovernmental dominance and limited #parliamentary oversight (Crum and Merlo, 2020). From a Bourdieusian perspective, the framing of these decisions as technical or fiscal necessities rather than as political choices constitutes a form of symbolic violence. Christoforou (2020), drawing explicitly on Bourdieu in an analysis of crisis and austerity in the EU, argues that the dominance of the financial field and the ascendancy of neoliberal norms work through mechanisms of misrecognition: citizens are conditioned to accept governance arrangements that serve specific class and capital interests as if they were natural, inevitable responses to economic conditions. This is not a neutral regulatory regime; it is a field structured by unequal distributions of capital in which the most powerful actors — particularly the German government and European financial institutions — impose their preferred governance logics on less powerful actors. The concept of #output_legitimacy also reveals its limits under crisis conditions. Starke and Lünich (2020), in an experimental study of citizen perceptions of EU decision-making, find that AI-assisted decision-making is not perceived as more or less legitimate than human decision-making on throughput and output dimensions, but that citizen participation (input) remains the most important dimension of perceived legitimacy. This suggests that output-based arguments for EU legitimacy face persistent public resistance because citizens fundamentally value participation, not just results. Wratil and Wäckerle (2022), using survey experiments across the five largest EU member states, further show that the congruence of EU decisions with majority opinion — not procedural inclusiveness as such — is the primary driver of legitimacy beliefs, through a "consensus heuristic." This is important: it suggests that citizens evaluate the EU against a majoritarian democratic standard, not against a technocratic regulatory one. 4.3 The Field of EU Governance and Structural Closure Bourdieu's concept of fields helps to reveal structural features of EU governance that Moravcsik's regulatory regime argument tends to obscure. The EU as a field is not equally accessible to all actors. Johansson, Uhlin and Arvidson (2021), in a study of career advancement in the European Economic and Social Committee, find that getting in, fitting in, and moving on within EU institutions requires specific forms of institutional capital — language proficiency, network connections, procedural knowledge — that are unequally distributed across EU society. This structural closure means that the EU field systematically advantages certain actors (educated, mobile, well-networked elites from core member states) over others. White (2021), writing in the European Journal of International Relations, extends this analysis to the broader dynamics of EU governance by arguing that more than a decade of crisis politics has seen EU institutions subordinated to informal networks of individuals, undermining the formal institutional structures through which accountability is supposed to operate. This de-institutionalisation of power beyond the state is not a minor procedural concern: it represents a drift from the legally-structured, procedurally-constrained governance that Moravcsik describes toward a more personalised, informal mode of rule that is harder to hold accountable. Agha (2024), in a Foucauldian-inflected analysis of the discourse of normalcy in EU governance, similarly argues that the EU's increasing reliance on the #rule_of_law and constitutional law as mechanisms of authority serves to legitimise and perpetuate existing power structures while marginalising alternative political projects. The Politics of the European Neighbourhood Policy offers a particularly instructive case. Cianciara (2020), applying Bourdieu's field theory to the ENP, demonstrates that EU institutions use legitimation narratives strategically — producing, reproducing, and reconstructing narratives of external policy in ways that serve internal EU institutional interests. The EU's external face is not simply a reflection of its internal governance quality; it is a legitimation strategy deployed by actors in the EU field to maintain their position. This suggests that the legitimacy of the EU as a regulatory regime cannot be assessed simply by examining its formal procedures; the sociological dynamics of the field also matter. 4.4 Isomorphism, Mimicry, and the Illusion of Legitimacy The institutional isomorphism framework adds a further dimension to the critique. If the EU's regulatory regime gains legitimacy partly by mimicking the appearance of well-designed, accountable governance — through the adoption of democratic narratives, the expansion of the European Parliament's powers, the creation of citizens' initiatives — without necessarily transforming the underlying power structures, then Moravcsik's argument may be confusing the symbols of legitimacy with the substance. Weigl and Reysner (2025) demonstrate this clearly in their analysis of the EU Digital Identity Framework. They find that mimetic isomorphism — the imitation of successful models like the GDPR — allows EU policy-making to gain legitimacy without necessarily ensuring robust democratic oversight. The GDPR model is used as a symbolic resource that confers regulatory authority on new instruments that may actually increase member state discretion and vulnerability to abuse. This is precisely what Bourdieu would predict: actors in the EU field use culturally recognised models of legitimacy as a form of symbolic capital, deploying them to accumulate institutional authority rather than to genuinely extend democratic accountability. Bora's (2026) concept of isomorphic spillover shows that the EU's regulatory powers expand through competitive, mimetic, and normative socialisation with sovereign states, making the EU progressively more state-like in its functional capacities while remaining institutionally unlike a democratic state in its accountability structures. The EU is, on this account, a regulatory giant that has adopted many of the outward forms of democratic statehood without the underlying constitutional infrastructure — a popular constituent power, a unified demos, effective mechanisms of collective self-governance — that gives democratic legitimacy its substance (Patberg, 2020). 4.5 World-Systems Perspectives: Who Benefits from the Regulatory Regime? World-systems theory asks a question that Moravcsik's argument does not: who benefits from the EU's regulatory regime, and who pays its costs? The single market, the euro, and the EU's competition and trade policies are not neutral regulatory infrastructure. They are structured in ways that reflect and reinforce the position of core European economies — primarily Germany, the Netherlands, and France — within the global capitalist system. The asymmetric management of the Eurozone crisis, in which peripheral states bore the greatest adjustment costs while core financial sectors were protected, is the most stark illustration of this structural inequality (Christoforou, 2020). Crum and Merlo (2020) find that the intergovernmental and output-oriented approach that informed EMU's original legitimacy remained dominant after the crisis, and that input legitimacy channels at the European level remain deficient across the three institutional innovations introduced in the crisis period. This is consistent with the world-systems prediction that intergovernmental governance structures in asymmetric political economies tend to reflect the interests of dominant states, rather than those of a broader community of equal participants. The framing of this as a merely technical #regulatory_regime — as Moravcsik's argument suggests — is therefore not politically innocent; it is a form of ideological legitimation that naturalises the existing distribution of power within the European political economy. Dingwerth, Schmidtke and Weise (2020) find that IOs' adoption of democratic legitimation narratives is driven significantly by public visibility and protest — that is, when IOs face external pressure from publics, they adopt the language of democracy, but in a path-dependent manner that does not necessarily reflect genuine procedural change. This suggests that the EU's democratic innovations are partly a response to external pressure rather than a sincere normative transformation, which further complicates Moravcsik's claim that the EU is genuinely legitimate as a regulatory regime. Democratic narratives, from a world-systems perspective, function as legitimating discourse that helps to maintain the stability of existing governance arrangements even when those arrangements systematically disadvantage peripheral actors. 4.6 The Populism-Technocracy Divide and the Limits of the Myth Argument A significant body of recent scholarship has approached the democratic deficit debate through the lens of the growing conflict between #technocracy and #populism in European politics. Foster, Grzymski and Brusenbauch Meislová (2021) argue that the EU faces accelerating challenges to its legitimacy in an era of "politics of necessity," in which member states have tended to "nationalise success and Europeanise failure." The EU has become a scapegoat for political failures whose origins lie partly in national policy choices, but it has enabled this dynamic by operating in ways that make it easy to narrate as a site of democratic illegitimacy. Mac Amhlaigh (2022) argues for a more realist approach to EU legitimacy, drawing on Bernard Williams' political realism to argue that the EU's endurance and expansion during a decade of crisis is itself evidence of a form of legitimacy, even if it does not satisfy normative theories of democratic authorisation. This is a sophisticated position that partially converges with Moravcsik's, in that it accepts that the EU need not meet the standards of national parliamentary democracy to be legitimate. However, Mac Amhlaigh insists that legitimacy requires historically contextualised justification, not merely effective authority — a condition that Moravcsik's regulatory regime thesis, with its relatively thin normative requirements, does not fully address. 5. Findings The analysis yields five principal findings that bear on the evaluation of Moravcsik's regulatory regime thesis. First, Moravcsik's benchmark choice — comparing the EU to other international organisations rather than to national democracies — is analytically defensible but politically insufficient. Citizens consistently evaluate EU governance against national democratic standards (Schraff, 2020; Wratil and Wäckerle, 2022), and the political legitimacy of the EU depends on satisfying at least a minimum version of those standards, not on outperforming the IMF. Second, Bourdieu's framework of fields and symbolic power reveals structural features of EU governance that the regulatory regime thesis obscures. The EU field is characterised by unequal distributions of institutional capital, structural closure that advantages well-networked elites, and the use of technocratic framing as a form of symbolic violence that naturalises politically contestable governance choices (Christoforou, 2020; Johansson, Uhlin and Arvidson, 2021; White, 2021). Third, world-systems theory situates the EU's regulatory regime within a global hierarchy of capital and power, showing that the governance arrangements Moravcsik describes as neutral and effective are structured in ways that systematically favour core-state interests and multinational capital over peripheral states and ordinary citizens (Crum and Merlo, 2020; Christoforou, 2020). Fourth, institutional isomorphism reveals that much of the EU's apparent legitimacy is produced through mimicry — the adoption of recognisable forms of accountable governance without necessarily ensuring the underlying democratic substance. Weigl and Reysner (2025) and Bora (2026) both demonstrate that the EU's expansion of regulatory powers through isomorphic processes creates legitimacy deficits that the formal regulatory regime framework cannot address. Fifth, the distinction between "technical regulation" and "political redistribution" that is central to Moravcsik's argument has been significantly eroded by the expansion of EU competences since 2002, and particularly since the 2008 financial crisis. The EU's exercise of authority over monetary policy, migration, digital governance, and environmental regulation involves deeply political choices that cannot be adequately governed through technocratic insulation (Fjørtoft and Sandven, 2022; Agha, 2024). These findings do not mean that the #democratic_deficit critique is always well-directed or that the EU is fundamentally illegitimate. They do mean that Moravcsik's argument, while insightful in important respects, cannot sustain the conclusion that the democratic deficit is a myth. It is, rather, a real but complex phenomenon that is partly obscured by inappropriate benchmarks, naturalistic framings, and institutional mimicry. 6. Conclusion This article has argued that Andrew Moravcsik's (2002) regulatory regime thesis offers a partial but ultimately insufficient account of EU democratic legitimacy. His core insight — that the EU should not be evaluated against an idealised version of national parliamentary #democracy but against comparable governance arrangements — is valuable and corrective. The EU's formal institutional architecture does contain genuine accountability mechanisms, and its performance on many governance dimensions is respectable by international regulatory standards. However, when evaluated through the combined lenses of Bourdieu's field theory, world-systems theory, and institutional isomorphism, significant limitations emerge. The EU field is structured by unequal distributions of capital and access, the regulatory regime naturalises the interests of dominant actors, and much of the EU's apparent legitimacy is produced through #institutional mimicry rather than substantive democratic transformation. Citizens evaluate the EU against democratic standards drawn from their national experience, and the EU's repeated failures of #output_legitimacy — from the Eurozone crisis to Brexit to the handling of the migration crisis — have generated persistent and legitimate grievances that the regulatory regime framework cannot resolve. The myth of the democratic deficit, it turns out, is itself partly a myth. There is a real deficit, though it is differently shaped than critics on both left and right often claim. It is not primarily a formal institutional deficit — the EU has become more formally democratic over time, with the expansion of #European_Parliament powers, the creation of the European Citizens' Initiative, and the Conference on the Future of Europe. It is a sociological deficit: a systematic pattern in which the structural features of the EU field, the dynamics of world-systemic inequality, and the isomorphic logic of EU regulatory expansion together produce a governance system in which certain voices, interests, and perspectives are structurally privileged over others. Addressing this deficit requires more than adjusting the benchmark of comparison. It requires serious attention to the social structure of EU governance, the distribution of power and capital within EU institutions, and the political economy of European integration. As Georgiev (2025) argues, self-organising, adaptive governance arrangements that bridge representation gaps may offer one path forward, but these must be grounded in genuine democratic participation rather than the sophisticated mimicry of participatory forms. The EU is indeed a novel form of political authority that demands novel democratic standards. Those standards should be neither as high as the ideal national parliament nor as low as the least accountable international organisation. They should be calibrated to the actual scope and consequence of EU power — which, as the first quarter of the twenty-first century has demonstrated, is very considerable indeed.
