As the PZPR leadership felt ready to sanction its rule in a fundamental legal document, a new constitution was being worked on. On 26 May 1951, the "Sejm" passed a statute concerning the preparation and passing of the constitution. The Constitutional Committee, led by Bierut, commenced its deliberations on 19 September. In the fall of 1951, a Russian translation of the draft constitution was examined by Stalin, who inserted dozens of corrections, subsequently implemented in the Polish text by Bierut. The officially proclaimed national public discussion resulted in hundreds of other proposed changes. After all the delays and the necessary extension of the term of the "Sejm", the Constitution of the Polish People's Republic was officially proclaimed on 22 July 1952.
