This course aims to introduce students to the fundamentals of EU Law. Specifically, it will provide students with a clear understanding of the constitutional foundations of EU law and its institutional structure. It will deepen students' understanding of the European judicial system and the relationship between EU law and the legal systems of the Member States. Considering that the legal system of the European Union is in a state of constant flux and change, emphasis will be laid on the dynamic architecture of the European Union, brought about by the Court of Justice when interpreting EU law and the successive amendments to the EU basic treaties. In so doing, students will reflect on current attempts to simplify the Union and redefine its sphere of competence and its inter-institutional allocation of power.
