The evolution of standards for the creation and extension of jurisdiction of the Court of Justice of the European Union in the founding instruments of the European Communities and the European Union in the pre-Lisbon period

The gradual evolution of the standards of the founding instruments of the European Communities and then the European Unionin the field of their judicial systems, which is subject to the integration processes in Europe, is comprehensively analyzed. Thoroughscientific works of both foreign and domestic scientists cover the problems of various spheres of development of the European Union,its institutions, in particular, its Court of Justice. However, the study of this topic was not given enough attention. Therefore, the purposeof the article is a comprehensive analysis of the evolution of the standards of the constituent instruments of these associations inrelation to the establishment and expansion of the jurisdiction of their Court of Justice in the pre-Lisbon period. It is established thatthe origins of the standards of the Court of Justice were enshrined in the founding treaties of the European Communities, and were furtherdeveloped in the founding instruments of the European Union, which were constantly being transformed. The jurisdiction of theCourt of Justice of the Coal and Steel Community was limited to a narrow sphere of economy, and with the entry into force of theTreaties establishing the European Economic Community and the European Atomic Energy Community (1958), the Court became ajoint institution for the three communities, with the powers of ensuring respect for the law in the interpretation and application of eachof the treaties.The peculiarities of the amendments made to the provisions of the following constituent instruments are discovered. The SingleEuropean Act (1986) provided for a certain unification of the legislation of Western European countries, supplementing the foundingtreaties of the Communities with new provisions on the establishment of the Court of First Instance to hear certain claims of individualsand legal entities to relieve the Court of Justice. The Maastricht Treaty (1992) formally proclaimed the establishment of the EuropeanUnion and defined the new structure of the Court of Justice (Court, Tribunal and Specialized Tribunals), its composition and powers,and powers of the Member States in the judicial field. The Amsterdam Treaty (1997) expanded the jurisdiction of the Court of Justiceof the European Union, namely certain areas of activity of courts, their cooperation with other competent authorities of the MemberStates, joint actions of judicial cooperation in criminal matters, etc. The Treaty of Nice significantly deepened the standards of thefounding instruments of the Court of Justice, expanded the powers of its judicial bodies and modernized its structure (including theCourt of Justice and the Court of First Instance), defined high requirements for judges and advocates general, the periods of theirreplacement, extended the jurisdiction of the Court of First Instance, etc. Further transformation of the standards of the Court of Justicehas been carried out under the Lisbon Treaty, which requires a separate study.
