The article explores coordination as a key organizational and legal mechanism for the functioning of the Unified System of Public Power in the Russian Federation. Coordination is viewed as an institutionally and normatively determined process of coordinating the activities of public authorities at various levels, aimed at ensuring their functional unity, coherence of management decisions, and holistic implementation of public functions. The article reveals the characteristics of coordination, its vertical and horizontal forms, and analyzes the risks of transforming coordination into a tool of directive administration that threatens the autonomy of local self-government. The article concludes that it is necessary to establish a regulatory framework for the delineation of powers, the development of control mechanisms, inter-level and inter-municipal cooperation, and the expansion of civil participation as conditions for the formation of a stable, effective, and legitimate coordination model in the public administration system.
