Abstract: The relevance of this study is that due to the conditions of the globalization of the world economy and the development of international commercial turnover, the importance of international commercial arbitration is rapidly increasing. There is also complexity and ambiguity in understanding the legal category of "public order" because this institution is not a definitively regulated area of law enforcement in the modern legal order. This article’s research object is the social relations arising through the activities of arbitration courts in international commercial turnover. This work aims to identify the procedures, mechanisms, and features of applying the public policy clause in recognizing and enforcing international commercial arbitration decisions. When writing this article, both general scientific research methods, including analysis, synthesis, deduction, and induction, and special methods of cognition, such as comparative legal and descriptive methods, were used. One of the main methods in this work is comparative law, as it helps identify the similarities and differences of the legal systems under consideration, which are the subject of the study. The novelty lies in consideration of the correlation of issues concerning the legal nature of "public order," as well as the analysis of cases related to the procedure of refusal to recognize and enforce decisions of international commercial arbitration in the territory of a foreign state based on contradiction to public order.
In the course of the study, the following conclusions were made. The complex problems that have formed in this area are almost impossible to solve by signing and putting into effect a single normative legal act at an international level. The list of cases applying this legal category in arbitration activities is non-exhaustive. The public policy clause is one of the most important components of the institutions of private international law. The institution of public order has an extraordinary character in the decisions of international commercial arbitration.
