This definitive work provides a comprehensive and authoritative overview of the practice and procedure of the Court of Justice and the Court of First Instance of the European Communities. It derives from a section in the looseleaf Law of the EU (Vaughan & Robertson, eds), and is made available here for the benefit of those who don't subscribe to the looseleaf. It details all aspects of procedure, covering direct and associated actions, references from national courts and appeals from the Court of First Instance, with full reference to the rules and relevant cases. It further covers the general principles of EU law established by the Court of Justice and the principles of interpretation of written EU law. The authors have taken account of recent important developments in the rules of procedure and case law and the continued growth of judicial activity in the European Union.
