Università Roma Tre

The seminar deals with various aspects of the relationship between the EU legal system and national legal systems. The German Federal Constitutional Court’s judgment of 5 May 2020 is an opportunity to investigate the limits of the European Union legal system and, more specifically, the role of the Court of Justice and its powers. The subject of the ruling was the legitimacy of the Public Debt Purchase Program, established by the European Central Bank. The German Court considers ultra vires and devoid of validity and effectiveness the previous judgment of the Court of Justice.
