6. The preliminary ruling (Article 267 TFEU)

This chapter examines the procedural law of the European Union (EU), focusing on Article 267 of the Treaty on the Functioning of the European Union (TFEU). It explains that Article 267 is the reference procedure by which courts in member states can endorse questions concerning EU law to the Court of Justice (CJEU). Under this Article, the Court of Justice of the European Union (CJEU) has the jurisdiction to provide preliminary rulings on the validity and interpretation of acts of the institutions, bodies, offices, or agencies of the Union and on the interpretation of the Treaties. This ensures legal unity.
