The current criminal procedure legislation provides a sufficiently detailed regulation of the process of proof in criminal cases. The object of proof, its means, the procedures of collecting, investigating, verifying and evaluating evidence are quite clear. However, both researchers and practitioners in the sphere of criminal court proceedings are still arguing about the rules of evaluating the results of operational investigative activities. Scholarly discussions at round tables and research conferences demonstrate that it is necessary to work out simpler algorithms for using operative information as evidence in a criminal case. Nevertheless, the procedural law still remains “at a standstill” and provides a rather superficial regulation of the evidentiary value of the results obtained during operational investigative actions. The author presents her opinion regarding the necessity of improving and optimizing means of proof by simplifying the procedural formalities of giving operational information the strength of evidence.
