This course aims to familiarise students with the law of the European Union, in the light of the Union’s system of governance and its political organisation. The course begins with an overview of the European integration process and its evolution. It also presents the Union’s mission, its objectives, its competences and the principles governing the latter’s exercise. The course then focuses on the Union’s institutional architecture, the role, powers and operation of the EU institutions, the EU legal acts and their making, the Union’s regulatory function and processes of differentiated integration. The course further examines key theoretical models of European integration and concludes with a presentation of fundamental manifestations of the Union, with emphasis on the Union as a Political Union, the Union as a Union of Values and the Union as a Union of Law.
