Abstract: International relations based on international treaties face the problem of states fulfilling their obligations. Fulfillment of obligations is the foundation of contractual legal relations, which is secured by responsibility of various kinds and types. The stability of international relations is extremely important, first of all, for maintaining peace, which imposes additional moral obligations on states. The principle of good faith in the fulfillment of international obligations covers many aspects of a moral and ethical nature; it is on the principle of good faith that, for the most part, the fulfillment of the terms of international treaties is based. This scientific article provides an analysis of the criteria for assessing the conscientious behavior of an entity in the fulfillment of international obligations, and identifies existing guarantees for the conscientious execution of international treaties. The study made it possible to determine some aspects of ensuring compliance with the terms of international treaties. The foundation for the fulfillment of international obligations is the principle of good faith, which is one of the guarantees of the implementation of international treaties. Conscientious fulfillment of the obligation is also supported by certain measures, together they ensure the fulfillment of international obligations by states. The principle of fair execution of international treaties is enshrined with an indication of the consequences of non-compliance with it, but clear criteria for assessing the good faith behavior of an entity are not normatively designated, which excludes a formal approach to assessing good faith and thereby is a kind of guarantee of fair execution of international treaties. There are other elements that ensure the conscientious execution of international treaties, these include: the procedure for concluding international treaties, the definition of its conditions, international control and surveillance, the state of the domestic legislation of any state.

Abstract: The subject of the study is the role of international organizations in the formation of an international legal system for countering cross-border cybercrime. The purpose of the study is to identify current trends in the work of international organizations in the field of the formation of regional and global legal systems for countering cybercrime. The system approach and formal legal approach are used as the main research methods. As a result of the study, specific features of regional international organizations and legal problems of countering cybercrime were identified, the question of the applicability of existing international law to cyberspace was analyzed. In particular, it is noted that at the moment modern international law is not capable of adequately and effectively countering cybercrime. The absence of a universal international legal act regulating the process of combating cybercrime is emphasized. On the other hand, the positive role of individual international organizations in the formation of the international legal system of counteraction is noted. In particular, the study describes the practice of forming expert groups by such organizations, as well as assistance to other regional international organizations in the process of creating their own international legal systems. One of the main conclusions is the conclusion that the absence of a universal UN legal document creates certain difficulties in the course of interstate coordination of procedural actions of law enforcement agencies and interaction of relevant international organizations. The author also concludes that the law-making experience of individual international organizations can be taken as a basis for the creation of a universal international legal act regulating the fight against cybercrime.

Abstract: The Arctic Council was established in accordance with the 1996 Ottawa Declaration as a “high level intergovernmental forum” for ensuring cooperation in the Arctic. It concentrates on the promotion of sustainable development and environmental protection in the Arctic. The scientific research conducted in the early 2000s under the auspices of the Arctic Council provided a more holistic representation of the problems of the Arctic and methods for their solution. Currently, the Arctic Council is the so-called coordinating center for the development of the Arctic legal order, being a place for negotiations, outlining the positions of the countries on specific issues, and establishing possible solutions to the problems. With the assistance of the Arctic Council, the Arctic sates have concluded certain treaties. Besides the eight Arctic states, which have authority for decision-making in the Council along with the right to discuss its policy and manage the six executive committees, the observing countries out of the non-Arctic states have been included to the Councils, although with restrictions in their powers thereof. The Arctic Council is recognized by the international community as the leading and responsible organizer of legal order in the Arctic Ocean that represents the interests of both Arctic and non-Arctic states. The involvement of non-Arctic states in the Arctic Council may improve the effectiveness of its activity in the sphere of sustainable development and environmental protection, as well as ensure their commitment to the results achieved within the Council and assert position of the Council as the most logical and appropriate place for the formation of international coordination in the Arctic.
