The rules on the competence of international courts determine the nature of the cases they resolve and the conditions for their admission to proceedings. The possibility composition of the court considers each case individually following the principle of jurisdiction to decide the jurisdiction due to the lack of a clear regulatory framework. Each international court of justice, relying on the international law, is solely competent to resolve doubts as to its own jurisdiction.
This study aims to identify the approach of courts to solving jurisdictional problems in practice. The material for the study includes the cases of international courts, doctrinal comments, and legal positions of prominent researchers of international justice.
The author describes the basic interpretative framework procedure, restraint, activism in the justification, and the lack of personal jurisdiction. Thus, if the international court of justice has no confidence in the existence of competence on the subject of the dispute, it will not take measures to justify it. The brevity of the position on the issue will be due to interpretative restraint. Activism arises when the international court of justice seeks to achieve a procedural result, substantiate the rationality of the result of interpretation or the impossibility of achieving it. Science has not resolved the issue of factors that may affect the limits of interpretation by international courts of their own competence.
