Abstract: The subject of this research is the norms of criminal procedure legislation regulating the application of preventative measures in criminal proceedings, as well as court decisions made on the basis of the results of processing applications on selection of preventative measures. Based examination of law enforcement practice, the expert observations and proposals in scientific literature, the author carefully analyzes the flaws of the current system of preventative measures in the criminal procedure, problematic aspects of correlation of restriction of certain actions, collateral, house arrest, as well as separate restriction, imposition of which upon a suspect (accused) is allowable in accordance with Part 6 of the Article 105.1 of the Criminal Procedure Code of the Russian Federation. The conclusion is made that the current system of preventative measures is not perfect, and practical application of various preventative measures reveals the formality of the established hierarchical structure of preventative measures in the criminal procedure legislation from soft to a more strict form. Analysis of case law demonstrates the it is often impossible to clearly and unambiguously demarcate the measures of prevention on form of a restriction of certain actions and collateral, restriction of certain actions and house arrest, which leads the author to conclude on the reasonableness of regulation of restriction of certain actions as another form of procedural compulsion.
