The aim of the research was the examination of modern methods of crime prevention related to the excess of official power or authority in the law enforcement system. The methodological basis of the study was the dialectical method of scientific knowledge, as the main method of objective and comprehensive analysis. The results highlight that over the past eight years in Ukraine 391 judgments, 4258 decisions on procedural actions were made during the consideration of crimes under Article 365 of the Criminal Code of Ukraine. The study of the Unified State Register of Judicial Decisions shows that the largest number of verdicts was pronounced in 2014 - 78, in 2015 - 58, in 2016 - 50, in 2017 - 46, the smallest number in 2018 - 28, in 2019 twice as much in comparison with the previous year - 46, in 2020 - 38, in 2021 - 47. Everything allows to conclude that, measures to prevent crimes related to abuse of power should be comprehensive. In particular, they must be effectively correlated with the legislative framework of the state’s protection and prevention policy, which signify the essential basis of any substantive democracy.
