EU Internal Market Law


Admission requirements

This course is a compulsory course of the International Business Law bachelor track.


The EU internal market is at the very heart of the European integration process. It comprises an area where the free movement of goods, persons, services and capital is ensured. This course will focus precisely on the internal market and its four fundamental freedoms. The free movement of goods, persons, services and capital will be studied through case-law of the European courts and their daily impact will be discussed: what are the consequences for natural and legal persons within the EU and how can their rights be protected? Can you establish yourself as a lawyer in other EU-Member States, can your family join, can your children get study grants? What are the rules behind French cheese, Belgian chocolate, Spanish wine and Swedish bread? These are just some of the issues which will be dealt with throughout this course.
Through exercises and class discussions, students will get a practical grasp of EU substantive law and will learn to work with the EU treaties and secondary EU legislation. Students will learn to read and analyse cases of the Court of Justice of the European Union (CJEU) and study some of its most important judgments.
