The purpose of the research is to determine the impact of the current administrative and legal regulation of the implementation of administrative procedures for the provision of the non-profit organisation state registration services on the scope of discretionary powers of the public administration in the provision of this service. The methodological basis of the research is created by modern philosophical, general-scientific and special-scientific methods of cognition including dialectical, logical, formal-legal, systemic and statistical methods, as well as analysis, description, synthesis and interpretation. The research results were the conclusions from the analysis of the administrative and legal regulation of administrative procedures for the provision of the non-profit organisation state registration services. Thus, in particular, the discrepancy between a separate provision of the administrative regulation on the provision of the non-profit association state registration services with the current federal legislation was identified and a proposal to amend it was formulated. In addition, it was concluded that the detailed regulation at the sub-legal level of the procedure for the implementation of administrative procedures for the provision of public services has a negative impact on the scope of discretionary powers of public administration bodies. The research novelty lies in the adopted methodological approach to the analysis of the overseas experience in legal regulation of the implementation of administrative procedures by public administration bodies and the conduct of a comparative legal study of regulation of the implementation of administrative procedures for the provision of public services in Russia and in the European Union member states.
