The exclusion of unreasonable discrepancies in the procedural regulation of similar (homogeneous) legal relations allows to increase the efficiency of justice, ensure timeliness correction of judicial errors, protect the rights and legitimate interests of the individual, strengthen the rule of law. The article analyzes some situations that confirm the tendency of significant lagging of the criminal procedural regulation of the control and verification stages from the effective, time‐tested norms and institutions operating in other types of legal proceedings. They are evaluated, and recommendations are also made for them concerning the unification (harmonization) of legislation, which regulates the review of court decisions by higher instances in the sphere of criminal proceedings.
