It aims to explore the various interactions, challenges, and future perspectives arising from the integration of these two legal systems. The conference provides a platform for legal scholars, practitioners, and policymakers to discuss the evolving landscape of public law within the European context. ## Committees & topics - Topics The Influence of EU Law on Belgian Constitutional and Administrative Law · The Implementation and Enforcement of EU Law in Belgium · Judicial Dialogue Between Belgian Courts, Constitutional Courts, and the CJEU · National Constitutional Identity and Its Role in EU Law · Fundamental Rights Protection in Belgian and EU Law · Migration, Asylum and Citizenship in Belgian and EU Law · Tax, Competition, Environmental and Social Law in the Belgian and EU Context · The Competences of the CJEU in Politically Sensitive Areas, Including Defence and CFSP ## Why it matters The interplay between national public law and European Union law is a critical area of study, particularly for member states like BEL. The decisions made at the EU level frequently impact national legal frameworks, necessitating continuous adaptation and interpretation. Understanding these dynamics is essential for maintaining legal coherence and ensuring the effective functioning of both national and supranational governance. This event offers a timely opportunity to delve into specific areas where these legal systems converge and diverge. Topics such as [administrative discretion](https://modeldiplomat.com/learn/glossary/administrative-discretion), as defined in legal scholarship, and the role of administrative tribunals are central to understanding how EU directives are implemented and enforced at the national level. The discussions will likely highlight areas of tension and best practices, contributing to a more nuanced understanding of legal integration. The insights gained from this conference are not limited to BEL. The challenges and perspectives discussed can offer valuable lessons for other member states as they navigate similar legal complexities. The event's focus on interactions and challenges underscores the ongoing need for legal professionals to stay abreast of developments in both national and EU law to ensure effective legal practice and policy formulation. ## How to prepare To prepare effectively for this event, participants should undertake a thorough review of recent developments in both Belgian public law and European Union law. A particular focus on areas where these two legal systems intersect, such as administrative law, constitutional law, and fundamental rights, would be beneficial. Understanding the historical evolution of this relationship and key judicial precedents from both Belgian courts and the Court of Justice of the European Union will provide a strong foundation for engaging in discussions. Participants should consider how specific EU regulations or directives have been transposed into Belgian law and the practical implications of these transpositions. Analyzing case studies or recent legal challenges that illustrate the interactions and potential conflicts between the two legal orders would be particularly insightful. This preparation will enable attendees to contribute meaningfully to the discourse and to identify areas for further research or policy development. Engaging with the concepts of "[administrative discretion](https://modeldiplomat.com/learn/glossary/administrative-discretion)" and the functioning of "administrative tribunals" within the Belgian legal system, in light of EU legal principles, will be crucial. Participants could also benefit from familiarizing themselves with the Model Diplomat lessons on "dynamic-analysis" and "what-is-stakeholder-mapping" to better understand the various actors and influences at play in legal policy formulation. Preparing specific questions related to the practical implications of EU law on Belgian administrative tribunals would also enhance participation. ## Country perspectives Where the most-relevant 1 countries stand on the core issues in play.

The landmark Le Ski judgment of the Cour de cassation in 1971 affirmed the primacy of directly effective international treaty law, including European Community law, over conflicting domestic legislation — a position reached without an explicit constitutional textual basis, in contrast to several other Member States. Article 34 of the Belgian Constitution, introduced in 1970 and revised since, provides the constitutional anchor for transferring sovereign powers to international and supranational institutions. Over decades, EU law has reshaped Belgian administrative law by importing principles such as proportionality, legitimate expectations, effective judicial review, and procedural rights. It has also pushed Belgium's federal architecture to accommodate EU obligations across the federal state, Communities, and Regions, with intra-Belgian cooperation agreements coordinating positions in the Council. Today, debate centres on how far EU primacy reaches into constitutional norms, the role of the Conseil d'État in applying EU principles, and the recalibration of administrative procedures under instruments like the GDPR and the services directives.

Cooperation agreements and the Concertation Committee coordinate transposition, but Belgium has historically faced infringement proceedings before the CJEU for delayed or incomplete transposition, particularly in environmental, internal market, and social policy fields. Enforcement relies on ordinary courts, the Conseil d'État for administrative acts, and the Constitutional Court for legislative norms, all of which are empowered to disapply national rules incompatible with directly effective EU law. The 2007 Lisbon Treaty reforms, combined with the EU's Better Regulation agenda and the European Semester, have intensified scrutiny of national implementation. Recent challenges include transposing the Recovery and Resilience Facility milestones, the Digital Services Act, and the asylum and migration pact, where Belgium's multilevel governance creates both flexibility and friction.

Together with the Cour de cassation and the Conseil d'État, it engages in continuous dialogue with the CJEU on questions ranging from non-discrimination and free movement to data protection and judicial independence. The Le Ski doctrine sets the baseline of primacy, while the Constitutional Court has carved out a role in reviewing legislation against both the Belgian Constitution and EU fundamental rights, often referring preliminary questions before ruling. This dialogue mirrors but also diverges from interactions between the CJEU and apex courts in Karlsruhe, Rome, or Warsaw. Belgian courts have generally avoided open conflict, but tensions surface over the scope of national procedural autonomy, the reach of the Charter of Fundamental Rights, and parallel review with the European Court of Human Rights under the Bosphorus presumption. Contemporary debates focus on how Belgian judges handle CJEU rulings on rule of law, Dublin transfers, and the application of EU law to politically sensitive matters such as data retention and arms exports.

The concept gained prominence through CJEU rulings such as Sayn-Wittgenstein and Coman, and through constitutional-court doctrines on identity review, most notably from the German Bundesverfassungsgericht, France's Conseil constitutionnel, and more recently Poland and Hungary. The debate centres on whether constitutional identity acts as a shield protecting core national values within EU law, or as a sword used to resist EU primacy. For Belgium, identity arguments have surfaced around federal balance, linguistic guarantees, and the protection of Communities and Regions. The Belgian Constitutional Court has generally engaged constructively with the CJEU rather than asserting a counter-limits doctrine, but questions arise over how Belgium's distinctive consociational and federal features should be accommodated in EU policy areas such as education, culture, and the rule of law conditionality regime. The 2022 CJEU ruling upholding rule-of-law conditionality reframed identity claims as bounded by Article 2 TEU values.

The Belgian Constitutional Court has developed an integrated approach, reading constitutional rights in light of the ECHR and Charter, and has been a frequent referring court on Charter questions, including in landmark cases on data retention and asylum. The relationship between the three systems is governed by Article 53 of the Charter, the Bosphorus presumption of the ECtHR, and the CJEU's Melloni and Åkerberg Fransson line of cases, which delimit when national higher standards may apply. The stalled EU accession to the ECHR — blocked by CJEU Opinion 2/13 in 2014 and now being renegotiated — adds another layer. Contemporary issues include the protection of privacy under the GDPR, non-refoulement in asylum cases, social rights in the gig economy, and judicial independence as a fundamental right under Article 47 of the Charter.

National asylum procedures are governed by the 1980 Aliens Act, repeatedly amended to transpose EU directives on reception conditions, qualification, asylum procedures, and returns. The 2015–2016 refugee crisis exposed structural weaknesses in the Dublin system, and Belgium has been the subject of CJEU and ECtHR rulings on reception conditions, including findings of inadequate housing for asylum seekers. The 2024 EU Pact on Migration and Asylum, adopted after years of negotiation, reshapes responsibility-sharing, screening at external borders, and solidarity mechanisms — all requiring substantial Belgian transposition. EU citizenship under Article 20 TFEU, developed through cases such as Ruiz Zambrano, Rottmann, and Coman, has also affected Belgian rules on family reunification, nationality, and same-sex partnerships. Ongoing debates concern statelessness, the rights of third-country nationals, judicial review of return decisions, and tensions between security policy and non-refoulement.

In tax law, Belgium's excess-profit rulings were challenged by the Commission as unlawful state aid, producing the 2019 General Court ruling and 2021 CJEU appeal that clarified the boundaries of selective advantage. The EU's adoption of the Pillar Two global minimum corporate tax in 2022 has required Belgium to overhaul its corporate tax framework. Competition policy is enforced jointly by the Belgian Competition Authority and the Commission under Regulation 1/2003. Environmental law in Belgium is largely EU-driven, from the Habitats and Birds Directives to the Industrial Emissions Directive and the European Green Deal package, including the Fit for 55 measures and the Carbon Border Adjustment Mechanism. Federal-regional competence divisions complicate implementation, as seen in long-running disputes over air quality and nitrogen emissions. In social law, EU directives on working time, posted workers, and platform work intersect with Belgium's strong collective-bargaining tradition. Current debates focus on the just transition, fiscal sovereignty under Pillar Two, and the social dimension of the Green Deal.

However, the Court has progressively pushed at the boundaries of this carve-out, asserting jurisdiction over restrictive measures against individuals (Kadi, Rosneft), staff disputes in CFSP missions (Elitaliana, H v Council), and the legal basis of CFSP acts where they intersect with the Union's other competences. Opinion 2/13 on ECHR accession highlighted the unresolved gap in judicial protection for CFSP acts. Russia's full-scale invasion of Ukraine in 2022 and the rapid expansion of EU sanctions regimes have intensified litigation before the General Court and CJEU, raising questions about due process, effective remedies, and the scope of Article 47 of the Charter in foreign-policy matters. The European Defence Fund, PESCO, and emerging defence-industrial policy under instruments like ASAP and EDIP further blur the line between internal market competences (Article 173 TFEU, Article 114 TFEU) and CFSP. For Belgium, host of NATO and a significant defence-procurement actor, these debates shape how national constitutional review and EU judicial review coexist in security matters.
