Abstract: | The ontological, terminological and conceptual confusion that surrounds the concept of ‘general principles of European Union law’ is far from being resolved. The constitutional interlocutors—the Court of Justice of the European Union and the highest courts in Member States—have at times fiercely argued about their different understanding of general principles, whereas European legal scholarship has failed to convincingly clarify the intricacies surrounding this source of law. Instead of engaging with a more abstract, theoretical question of what general principles are, this paper reflects on the practical, functionalist question: how are they used by the Court of Justice and what are some of their functions and implications? To do so, it enquires into contextual, institutional and strategic features of the Court's behaviour and jurisprudence and responses of the highest national judiciaries to this jurisprudence. The aim is to offer an alternative account of the Court's jurisprudence on general principles. |
