The article discusses the ambiguously evaluated by process scientists the possibility of using the probable conclusion of an expert in proving a criminal case. This discussion arose quite a long time ago, continues at the present time and, apparently, will continue in the foreseeable future. There are indeed grounds for this, since the expert’s probable conclusion can also be interpreted in favor of the person against whom criminal prosecution is being carried out, since it does not contain a categorical conclusion about the reliable establishment of the investigated circumstance of the subject of proof or the fact constituting it. Scientists in this regard express diametrically opposed opinions, but in the overwhelming majority they are blamed for the fact that the probable expert opinion is subject to evaluation along with other evidence and, under certain conditions, can be combined with other evidence to form the basis of procedural decisions, including those made by the court. It should be noted that currently neither the Criminal Procedure Law nor Federal Law No. 73-FZ of 31.05.2001 “On State Expert Activity in the Russian Federation” provides for the division of expert opinions into categorical and probable, although such a classification exists and is recognized by the legal community. There is no explanation about this in the resolution of the Plenum of the Supreme Court of the Russian Federation No. 28 dated December 21, 2010 “On forensic examination in criminal cases”. At the same time, the said resolution does not prohibit the use of probable expert opinions in criminal proceedings, unlike the previously valid resolution of the Plenum of the Supreme Court of the USSR of 16.03.1971 with the same name. The author shares the position of scientists who believe that it is possible to use the expert opinions under consideration in proving a criminal case, including when maintaining state charges in court. In turn, the validity of this position is confirmed by the materials of the study of prosecutorial and judicial practice. examples of which are given in this article. At the same time, the lack of specificity of the conclusions contained in the probable expert opinions should force prosecutors to take a particularly careful approach to their research and evaluation before deciding on the validity of references to them in indictments and using them in proving the validity of the prosecution’s position in court. The nature of this decision is largely influenced by the degree (level) of probability of the expert’s conclusion, as well as the absence of contradictions between it and other evidence. According to the author, in order to eliminate disagreements regarding the use of probable expert opinions in criminal proceedings, it is advisable to include provisions establishing their legal status in the Federal Law on State Forensic Expert Activity and in the Criminal Procedure Law.
