From Van Gend en Loos and Costa v ENEL to Cassis de Dijon and Consten and Grundig, Landmark Cases in EU Law explores the most important and well-known EU law cases in two volumes. These volumes show how the European Court of Justice has played a fundamental role in the construction of the European Union in the past 70 years. Many EU 'landmark' cases have been controversial, yet no-one can deny that they have been essential in defining the Union legal order as we find it today. Volume 1 explores the 'constitutional' cases that have come to define the legal nature and competences of the Union, its judicial architecture as well as its fundamental rights system. Each of the twenty cases within this volume is placed in its historical and doctrinal context, and each chapter also presents the history of its reception by the Court and academia.
