The article reveals the problematic issues of the appointment and production of forensic examinations in the criminal procedure legislation of the Republic of Kazakhstan. The authors of the article analyzed the norms of the criminal procedure law, as well as the current state of judicial and investigative practice on the appointment of expert examinations. In the process of analyzing the criminal procedure law, a comparison of the legal status of ‘expert and specialist’ in the legislation of Kazakhstan was also made. The analysis will allow the legislators of the post-Soviet countries to take into account the shortcomings described in the construction of the norms of the criminal procedure law. For example, an analysis of the norms of the criminal procedure law shows that today the expert is deprived of the opportunity to go beyond the list of questions. The foregoing leads to the fact that some aspects important for the investigation remain without consideration. This negatively affects the resolution of the tasks of the criminal procedure law.
