This contribution seeks to highlight certain aspects of judicial review exercised by the Court of Justice of the European Union in order to compare them with the judicial review exercised by Lithuanian courts. These aspects will mainly cover the standard of judicial review (limited v unlimited review), the competence of the respective courts, as well as procedural aspects which can affect practical exercise of this review. As both the EU courts and national courts can be called upon to apply the same provisions of EU law (for instance, in competition law cases), and, moreover, national authorities can sometimes refer their cases to Union institutions, the differences in the exercise of judicial review and in procedural rules might lead to different outcomes depending on whether the administrative decision was taken by a national or by a Union authority and subject to review by national or by EU courts. I will therefore examine whether, in light of the principles of equivalence and effectiveness, some convergence may be desirable.
