the process of judicial proceedings in the court of the first instance, the only subject of
evaluation of testimony and evidence is the court.
Evaluation of the testimony of a suspect, accused, witness, victim, an expert in a court of the first instance is the mental logical activity of a judge, which consists of the fact that, guided by the law and legal consciousness, the judge, according to his inner conviction, considers the information contained in the testimony separately, as well as in conjunction with other evidence determines their belonging, admissibility, reliability, and sufficiency for making intermediate and final decisions in judicial criminal proceedings.
