Abstract: The study of the problems of international legal responsibility as one of the basic elements of international legal regulation is of particular importance due to the fact that the subjects of international law, taking advantage of the dispositivity and consensual nature of its norms, abuse them in their own interests, often seriously infringing the interests of their international partners. The institution of international legal responsibility is one of the earliest forms of interstate relations that arose long before the formation of public international law as a legal system. The article discusses the forms of compensation for harm in public international law. The property and non-property forms of compensation for harm are highlighted. The key characteristics of international legal responsibility are defined, such as compensation for harm, as the most effective sanction for unlawful actions, and restoration of the violated rights and interests of the victim. The analysis of the order and consequences of the application of forms of international legal responsibility is given. The institute of international legal responsibility is very extensive, we have considered only some of its part concerning the forms of international legal responsibility. Forms of international legal responsibility can be of a property and non-property nature. Property forms of liability include: restitution, compensation, satisfaction. Non-property forms of responsibility include: retorsions and reprisals. As a result of the conducted research, it is concluded that the forms of liability are most effective when they are combined when several property forms of liability (for example, restitution and compensation) are used together with non-property forms of liability. It is noted that non-property forms of liability are the most effective in terms of influencing the reputation of the harm-doer, due to their publicity.

Abstract: The subject of the study of this article is some aspects of the problem of nuclear disarmament, which are highlighted, among other things, from the perspective of the ongoing military special operation in Ukraine. The history of the creation of the nuclear disarmament regime is traced. The main documents regulating the procedure of nuclear disarmament are characterized. The ways of strengthening and finding a compromise in the issues of nuclear disarmament in the world have been identified. The analysis of the problem of nuclear disarmament, which is at the center of international relations and is relevant in the theory of international law, is given. The author has studied the international legal regulation of nuclear disarmament, identified its problematic aspects. The main documents in the field of legal regulation of nuclear disarmament are the Treaties on the Non-Proliferation of Nuclear Weapons, the Comprehensive Nuclear Test Ban Treaty, as well as the International Monitoring System created for its implementation. The existing international legal system of control over nuclear disarmament, non-nuclear testing, and the use of atomic energy exclusively for peaceful purposes does not always prove its effectiveness, as a result of which countries with unstable political situation possess nuclear weapons, which entails an additional threat to the world community. As a result of the analysis, it was concluded that the current system of international monitoring of nuclear tests and the system of international regulation of nuclear disarmament need to be modernized in order to eliminate the threat of proliferation and use of nuclear weapons. Currently, the development of technologies for the enrichment of radioactive substances, the emergence of new threats and other factors create significant obstacles to the preservation of the nuclear disarmament regime.
