The paper aims at analysing the understanding and application by the European Court of Justice of the principle of effective judicial protection in the context of composite administrative proceedings. Recently, the Court has had to adjudicated on a case which arose in the context of the new Banking Union set up following the Eurozone crisis and which concerned the question of the exact division of tasks between the ECB and the national authorities, and its implications in terms of judicial review. Is the Court's jurisdiction exclusive and total, englobing the preparatory acts adopted at the national level, or is it split between the Court and national judiciaries, depending on the author of the act at stake? The court revisited in its ruling the long-standing Borelli case law and shed new light on the division of competences between national and European courts when shared execution of EU law is at stake.
