In the law of the Soviet Union, judicial supervision (Russian: судебный надзор) was a system for review of court sentences, orders, and decrees that have entered into legal force.
It was regulated by the Article 48 of the Basic Principles of Criminal Legislation of the USSR and the Union Republics.
[1] Judicial supervision was carried out by the bodies of Supreme Courts of the Union Republics, and in a limited number of situations by the Supreme Court of the Soviet Union.
[4] [5] William Partlett argues that this practice, historically grounded in the legal practice of the Russian Empire, was "justified as a way of ensuring a centralised vertical of power for Party policy" and enforced legality by reviewing the administrative and judicial decisions.
This practice was re-used in legal lystems of other communist states.
