On the problem of admissibility of evidence

This article addresses the issue of the admissibility of evidence in criminal proceedings, specifically focusing on the use of results from operational investigative activities, expert conclusions, and testimonies. Until now, the issues of their legalization and recognition as admissible evidence remain controversial. The relevance of this study is underscored by the need in legal theory and practice to recognize the distinct role of non-procedural information in criminal proceedings, which holds significance for the case, and to develop approaches to its legal interpretation and application, considering the sources and methods of its acquisition. The aim of this publication is to justify the necessity of fully reflecting the results of operational investigative activities and expert studies in the materials of pre-trial investigation and criminal cases for subsequent judicial review. To achieve this goal, a number of tasks are solved, including: analysis of approaches to understanding the stated problem that have emerged in the scientific legal literature, determination of legal ways to solve it within the framework of current legislation. An overview of the procedural process of judicialization is provided, with emphasis on the possibilities of interrogating personnel conducting operational support and specialists performing individual studies, the results of which are then subject to verification and evaluation in accordance with the requirements of relevance and admissibility of evidence. In conclusion, the integration of operational investigative results and expert analyses as admissible evidence in criminal proceedings requires balanced approaches that uphold procedural integrity while accommodating the complexities of modern investigative techniques. By advancing these discussions, policymakers and legal practitioners can foster a more robust framework for evidence evaluation and judicial decision-making.
