Genesis of the Institution of Denunciation in the Theory and Practice of the Law of Treaties

International treaties throughout the history have always played a key role in regulating relations between states. However, the constant development of international law and the changing conjuncture of international relations have led to both the conclusion and withdrawal from international treaties. The doctrine of international law, including the history of international law and the law of treaties, focuses more on the procedures of signing, conclusion and entry into force of international treaties, while the issues of termination of international treaties have less attention from international legal scholars. The relevance of the topic of denunciation of international treaties is due to both the difficulties arising in the exercise of the right to denunciation and the need for a detailed international legal regulation of this process. In order to identify the essential characteristics of the institution of denunciation of international treaties, the article conducts a comprehensive historical and legal analysis using the methods of comparative legal research. The novelty of this article lies in systematizing the evolution of the right to denunciation of international treaties from exogenous to endogenous character, as well as in identifying the influence of political factors on its practical implementation. For the first time, these developments are considered in the context of the fundamental principle of the law of treaty - pacta sunt servanda. It is noted that the institution of denunciation of international treaties has undergone significant evolution since ancient times. The key role in its formation was played by the London Convention of 1871 and the Vienna Convention of 1969. These documents were used to develop the periodization of the right to denunciation, which includes three stages. The existing international legal framework regulates the application of the right of denunciation in a non-exhaustive manner, resulting in a fragmented practice. Further development of this institution requires the unification of norms and mechanisms of control of the right to denunciation to prevent abuse of this right and to ensure the stability of international treaties.
