Democracy at the Borders: Analyzing the Role of Democratic Principles in EU External Relations Law

This paper critically examines the constitutional status and practical role of democracy within European Union (EU) law, with an emphasis on external relations. Although democracy is enshrined as a fundamental value in Article 2 of the Treaty on European Union and further operationalized in other Treaty provisions, its constitutional significance remains limited compared to principles such as conferral or institutional balance. The analysis reveals that democracy functions primarily as a weak background principle, informing but not directly determining the judicial review of secondary EU law measures. This status reflects the historical absence of a robust democratic framework in the EU’s institutional design and the comparatively limited powers of the European Parliament, the Union’s main democratic body. The paper traces the evolution of democratic principles within EU law, highlighting the gradual inclusion of democracy as a membership criterion and the ongoing scholarly debates over the EU’s democratic deficit. Through a descriptive review of key CJEU case law (including Roquette Frères, Titanium Dioxide, and Chernobyl), the paper shows that democracy is seldom invoked as a decisive constitutional principle. In external relations, democratic concerns have featured implicitly rather than explicitly in legal controversies. The paper concludes that meaningful democratization of EU external relations will require not only strategic litigation based on specific Treaty provisions but also substantive Treaty reform to strengthen the constitutional standing of democracy within the EU legal order.
