jus cogens norms, erga omnes obligations, principles of international lawAbstract
The fundamental basis of modern international law are the norms of jus cogens and obligations erga omnes, which act not only as criteria and guidelines for the legality of all elements of the international legal system, but also allow this system to develop exclusively in a progressive direction. At the same time, there is no consensus in the international legal doctrine regarding the nature, sources and content of these concepts. Even more controversial is the problem of the relationship between the norms of jus cogens and obligations erga omnes, which is the subject of this article. The authors examine the concepts of these norms from the standpoint of their similarities and differences, as well as full and partial identity, and analyze the mechanisms of their interaction. As an additional aspect for identifying the relationship between the norms of jus cogens and obligations erga omnes, the authors turn to the norms regulating the cooperation of states in the fight against international crimes. In their study, the authors rely on extensive international legal doctrine, state practice, universal international treaties, documents of the International Law Commission and decisions of the International Court of Justice.
