The purpose of this article is to analyze the review procedure of the reprivatization decision in proceedings before the Commission for the reprivatization of the real estates in Warsaw. Proceedings before the Commission are recognized as a special type of extraordinary verification of decisions. The Act on the Commission contains regulations departing from the Code of Administrative Procedure, which arise, inter alia, from the special political position of the Commission and the subject of the proceedings. The control of the correctness of the reprivatization decision was based on the theory of gradation’s defects developed in the doctrine, which takes into account the violation of the social interest.
