The article deals with the relations between the European Judicial Network (EJN), Eurojust, and the European Public Prosecutor’s Office (EPPO) , in particular the question of how to shape their relationship. Direct communication between Member States’ judicial authorities is the underlying principle of international cooperation in criminal matters in the EU. This needs to be reflected in the legal instruments covering international cooperation. Technical platforms for secure electronic communication between judicial authorities must be designed in such a way as to facilitate direct communication and should not lead to an enhanced role for central authorities.

The current EU approach to jurisdictional conflicts is discussed in the first part of this article. The article highlights the persistent problems of the existing legal framework as well as those emanating from Eurojust’s approach to the matter. After linking the topic with the ne bis in idem principle, the Member States’ interests in prosecuting criminal offenses under their competence, and the EU’s objective in the AFSJ when fighting impunity, the author presents some pivotal reflections on a better solution in the second part. Any solution first and foremost has to respect the EU’s main characteristic as a supranational organisation aligned to its constitutional treaties and to its Charter of Fundamental Rights.
