The article briefly discusses the main provisions of federal laws that affect some of the legal problems that arise for a municipal employee when organizing interaction between local governments and other public authorities. As a basic example, the process of implementing the right of local governments to take measures in the field of crime prevention is analyzed as a specific part of the competence, implying the need for interaction. The uncertainty of the content of the terms “measure” and “sphere” related to the prevention of offenses and generating legal implementation problems that need scientific study is indicated. A variant of their resolution is proposed by comparing these terms with the lists of “forms of preventive actions” and “areas of crime prevention”. The concept of the article is based on a subject-centered approach from the perspective of a municipal employee responsible for organizing and implementing interaction with state authorities at both the federal and regional levels of government. Examples of implicit, complex and nonuniform solvable problems accompanying the interaction of public authorities, including those related to significant differences in the legal awareness of subjects, are given. Attention is drawn both to the complexity and multi-stage nature of the process of local self-government bodies exercising certain state powers, as well as to the specifics of participation in the exercise of powers that have not been transferred in accordance with the procedure established by law.
