Abstract
The paper presents the development of public procurement regulations in the Second Polish Republic between 1933 and 1939, with particular focus on the Act on Supplies and Works of 15 February 1933 and the implementing regulation of the Council of Ministers dated 29 January 1937. It examines the subject scope, preference system and procedures for awarding supplies and works contracts, the contract content and execution rules, as well as mechanisms of control and liability. To broaden the understanding of procurement practices at the time, the article also includes a limited analysis of local regulations adopted by the city of Poznan. The regulation of the Council of Ministers, regarded as one of the most modern in pre-war Europe, was used as a model even after 1989. This not only confirms the continuity of the civil-law model of public procurement in Polish legislation, but also justifies the relevance of revisiting these solutions for contemporary readers.
