The article examines the problems of the content and legislative consolidation of the category of "legitimate interests" of a person subject to criminal prosecution. The article analyzes the theoretical and legal nature of the term "legitimate interests" and its relation to subjective rights. Contradictions and gaps in the use of this category in the Code of Criminal Procedure of the Russian Federation, the Federal Law "On Operational Investigative Activities" and other regulations are identified. Proposals are being formulated to improve legislative techniques and mechanisms for protecting legitimate interests.
This article examines current issues in assessing the results of operational investigative activities (OSI) in criminal proceedings. This is due to the fact that OSI results do not always meet the requirements of criminal procedural evidence, leading to legislative gaps and difficulties in their consistent application.
