Professor Tridimas has co-authored a study looking at the role of customary international law in EU law. The study explores the identification and application of customary international law by the Court of Justice of the European Union (CJEU). As the importance of the European Union as an actor in international law has increased, so have references to customary international law in the case law. The CJEU’s approach is not always consistent, striving to achieve a balance between respect for international law and EU law autonomy. The article engages, among others, with the duty of consistent interpretation, and the Front Polisario cases, which mark a turning point on the CJEU’s international law jurisprudence.
