Introduction. The development of the institution of parliamentary control in the Russian Federation actualizes the issues of achieving a balance of branches of government at the regional level and improving legal regulation in order to increase the effectiveness of the constitutional and legal mechanism to meet the interests and needs of residents of the respective regions. Theoretical analysis. At the present stage, there is a variety of forms of legal regulation of parliamentary control at the regional level, different legal models of its legislative regulation, characterized by certain advantages and disadvantages, are used. This determines the need to unify the conceptual and terminological apparatus of this institution, that reflects its essence and characteristic features, as well as the legislative consolidation of basic parameters, internal constitutive principles and procedures that ensure the inclusion of subjects of regional parliamentary control in the system of parliamentary control of the Russian Federation. Empirical analysis. The analysis of the legislative consolidation of procedural issues of the implementation of various forms of parliamentary control by regional parliaments indicates the conciseness of the relevant legal regulations, the planned nature of control procedures, the reproduction of the powers of the federal legislature at the regional level based on the results of verification activities with some expansion of such opportunities. The powers of a regional legislative authority based on the results of the exercised control, which are not provided for by similar norms of federal legislation on parliamentary control, can be differentiated into recommendations addressed to regional state structures, personnel decisions, initiating communications in the form of drafting a draft law of a subject of the Russian Federation, a draft federal law for its introduction by the legislative authority of a subject of the Russian Federation in the exercise of the right of legislative initiatives to the State Duma of the Federal Assembly of the Russian Federation. Results. The authors conclude that the legislation and practice of parliamentary control in the Russian regions need to be improved, which is aimed at detailing the legal regulation in this area and increasing effectiveness of its implementation. In this regard, the prospects for the adoption of the federal law “On general principles of parliamentary control in the subjects of the Russian Federation” are substantiated.
