The adaptation of the administrative justice system to EU requirements is becoming a strategically important task for Ukraine in the context of approximation to European justice standards. Transparency is a key feature of the EU judicial system that guarantees public control, public trust in the courts, openness of court procedures and the efficiency of administrative proceedings to ensure quick and fair resolution of public law disputes. In general, the application of European standards to the Ukrainian administrative justice system has its relevance and prospects, however, it is also necessary to take into account certain problems that arise during adaptation. The purpose of this study is to provide scientific arguments and recommendations for Ukrainian legislators and executive bodies to achieve greater compliance with European standards in the field of administrative justice.
