The article raises the question of the necessity of introducing legal mechanisms to ensure the unity of jurisprudence in the area of sentencing. It is proved that the unity of court practice in matters of sentencing is not less important than unity in matters of courts of substantive and procedural law, as far as punishment is a measure of coercion, which largely affects the set of rights and responsibilities of individuals. We present arguments for the introduction of an extraordinary review of judicial decisions which became final, by the court of cassation. It is suggested that the implementation of the proposition, made in articles within this concept would contribute substantially to improving the domestic legal system and ensure the existence of legal tools that are necessary for the implementation of state policy in the sphere of sentencing.
