Abstract: The study is devoted to problematic aspects of the definition of the concept of "prohibition of certain actions", as well as its legal nature.
Since the introduction of the prohibition of certain actions into the mechanism of criminal procedure regulation (Article 105.1 of the Code of Criminal Procedure of the Russian Federation), various aspects of the functioning of the institution in question have been discussed in the scientific community. However, little attention has been paid to the issue of the legal nature and concept of this measure. The existing approaches to definition are reduced either to discussing the nature of procedural restraint or coercion in general, or listing the prohibitions established by Article 105.1 of the Code of Criminal Procedure of the Russian Federation, thereby forming the scope, not the content of this term. It seems appropriate to define the concept of "prohibition of certain actions" by establishing its legal nature, basic idea and purpose. The legal nature, the main idea and purpose of the prohibition of certain actions are revealed, the author's understanding of the term is formulated, and the classification model of prohibitions provided for by this measure is determined in the article. Firstly, the purpose of the prohibition of certain actions is to ensure guarantees of compliance with procedural deadlines; prevention of reputational risks during the rehabilitation procedure; reduction of the financial burden of the state budget by optimizing the number of detainees; exclusion of excessive and inappropriate restrictions on individual rights. Secondly, the main idea is to reduce the negative impact of criminal procedural coercion on a person without threatening the effectiveness of criminal proceedings. Thirdly, the scheme of the legal nature of the prohibition of certain actions (from general to particular): legal prohibition – prohibition as an instrument of the mechanism of criminal procedure regulation – prohibition in criminal law (substantive and procedural) – prohibition of certain actions. Fourth, prohibitions (Article 105.1 of the Code of Criminal Procedure of the Russian Federation), depending on their nature, are classified into spatial, communicative and licensing-permissive. Fifthly, the prohibition of certain actions is a method of criminal procedural regulation that performs the deterrent and binding functions of suppressing influence on a suspect (accused) in the interests of criminal justice, which is a legally established minimum possible restriction on freedom of movement (stay), the implementation of licensing and licensing activities and (or) communication of an individual without isolation from society.
