This fully updated and revised second edition of Preliminary References to the European Court of Justice provides a meticulous and yet easily accessible examination of all aspects of the preliminary reference procedure. Since the first edition there have been significant changes to the European Union's legal foundations. First and foremost of those being the signing of the Lisbon Treaty, which has had both direct and indirect consequences for the preliminary reference procedure. In addition, the authors have taken into account amendments to the Rules of Procedure of the Court of Justice and the Court's amended Statute, they have added expanded treatment of the acte clair doctrine and the Court's Cartesio ruling and a more general revision of the text bringing it up to date by taking into account new case law and new legal writings. In addition to these important updates, the authors have also revised the structure of the book. With backgrounds as both practitioners and academics the two authors have produced a book that caters for the needs of both practitioners and academics.
