Introduction
This essay critically evaluates Franz C. Mayer’s argument, as presented in his 2010 article, that the landmark case of Van Gend en Loos v Nederlandse Administratie der Belastingen (Case 26/62) initiated the constitutionalisation of the European legal order, ultimately establishing what the European Court of Justice (ECJ) described as a “new legal order of international law.” Mayer posits that this 1963 judgment by the ECJ was a transformative moment, setting the foundation for a supranational legal framework distinct from traditional international law (Mayer, 2010). The essay will explore Mayer’s perspective by first outlining the key aspects of the Van Gend en Loos ruling, then assessing his argument on constitutionalisation through the lens of direct effect and the relationship between national and European law. Finally, it will consider alternative viewpoints and limitations to Mayer’s interpretation. This analysis aims to provide a balanced critique, drawing on academic literature to evaluate the significance of the case in shaping European Union (EU) law.
The Van Gend en Loos Case: A Turning Point in EU Law
The Van Gend en Loos case, decided in 1963, involved a Dutch company challenging a customs duty imposed by the Netherlands, arguing it violated Article 12 of the Treaty of Rome (now Article 30 TFEU) which prohibited increases in customs duties between Member States. The ECJ’s ruling was groundbreaking, as it established the principle of direct effect, meaning that certain provisions of EU law could confer rights on individuals enforceable in national courts, independent of national legislation (Craig and de Búrca, 2020). The Court famously declared that the European Economic Community (EEC) constituted “a new legal order of international law for the benefit of which the states have limited their sovereign rights” (Case 26/62, 1963).
Mayer (2010) argues that this judgment marked the starting point of constitutionalisation by redefining the relationship between the EEC and its Member States. He suggests that the ECJ’s assertion of a distinct legal order elevated the Treaty of Rome beyond a mere international agreement, transforming it into a constitutional framework. Indeed, the notion of a “new legal order” implied a hierarchical structure where EU law could take precedence over conflicting national laws, a concept later formalised in Costa v ENEL (Case 6/64, 1964). Mayer’s interpretation, therefore, centres on the transformative potential of Van Gend en Loos in creating a supranational system akin to a federal constitution.
Constitutionalisation and the Role of Direct Effect
A key pillar of Mayer’s argument is the role of direct effect in constitutionalising EU law. By granting individuals the ability to invoke EU law directly before national courts, the ECJ effectively bypassed traditional international law mechanisms, which typically rely on state compliance (Mayer, 2010). This shift, Mayer contends, mirrored the function of a constitution in domestic systems, where citizens can directly rely on constitutional rights. Furthermore, it empowered individuals as stakeholders in the European project, fostering a sense of legal community beyond national boundaries.
Supporting Mayer’s view, scholars such as Weiler (1991) argue that direct effect was instrumental in creating a dynamic interplay between national and European legal systems, integrating EU law into the daily functioning of Member States. However, it is worth noting that direct effect, as articulated in Van Gend en Loos, was initially limited to clear, precise, and unconditional provisions, suggesting that the immediate constitutional impact may have been narrower than Mayer implies (Craig and de Búrca, 2020). While the principle undeniably laid groundwork for deeper integration, its gradual development through subsequent case law (e.g., Defrenne v Sabena, Case 43/75) indicates that constitutionalisation was more iterative than instantaneous.
Supranationalism versus National Sovereignty
Mayer (2010) further asserts that Van Gend en Loos reframed the EEC as a supranational entity, distinct from traditional international organisations. By describing the Treaty as creating a legal order binding on both states and individuals, the ECJ challenged the notion of absolute national sovereignty, a hallmark of a constitutional shift (Weatherill, 2016). This perspective aligns with the idea that EU law operates as a higher norm, compelling Member States to adapt their legal systems to accommodate European obligations.
Nevertheless, this argument is not without its challenges. Critics argue that the constitutionalisation narrative overstates the willingness of Member States to cede sovereignty. For instance, while the ECJ’s rhetoric in Van Gend en Loos was bold, national courts did not immediately embrace the principle of direct effect, with resistance evident in several jurisdictions during the 1960s and 1970s (Stone Sweet, 2004). This suggests that the constitutionalisation process was contested and uneven, raising questions about whether Van Gend en Loos alone can be credited with initiating such a profound transformation. Arguably, Mayer’s emphasis on the case as a singular foundational moment may downplay the cumulative effect of subsequent judicial and political developments.
Alternative Perspectives and Limitations
While Mayer’s analysis is persuasive in highlighting the symbolic and legal significance of Van Gend en Loos, alternative perspectives suggest that constitutionalisation was neither inevitable nor solely attributable to this case. For example, Stein (1981) argues that the broader context of European integration, including the political will of Member States and the role of later treaties like Maastricht (1992), played an equally important role in shaping the EU’s constitutional character. Indeed, the formalisation of concepts such as EU citizenship and fundamental rights in later treaties suggests that constitutionalisation was a gradual process, rather than a direct outcome of a single judgment.
Moreover, Mayer’s focus on the ECJ’s agency risks undervaluing the resistance from Member States and the practical challenges of implementing a “new legal order.” National governments have, at times, sought to limit the scope of EU law through political negotiations or judicial pushback, as seen in debates over the Charter of Fundamental Rights (Stone Sweet, 2004). Therefore, while Van Gend en Loos undeniably set a precedent, its role as the cornerstone of constitutionalisation may be overstated in Mayer’s account.
Conclusion
In conclusion, Mayer’s argument that Van Gend en Loos initiated the constitutionalisation of the European legal order through the establishment of a “new legal order of international law” carries significant weight, particularly in its emphasis on direct effect and the redefinition of sovereignty. The case marked a pivotal shift by empowering individuals and asserting the autonomy of EU law, laying the groundwork for a supranational system (Mayer, 2010). However, this essay has highlighted limitations in Mayer’s interpretation, noting that constitutionalisation was a gradual and contested process influenced by broader judicial, political, and Treaty-based developments. While Van Gend en Loos was undoubtedly transformative, its impact must be contextualised within the evolving landscape of European integration. Consequently, Mayer’s argument, though compelling, benefits from a more nuanced consideration of complementary factors and challenges. This analysis underscores the complexity of the EU’s legal evolution, with implications for ongoing debates about the balance between national sovereignty and supranational authority in the European project.
