The subject of the article are issues related to the composition of the deputies’ chamber during the Piotrków General Sejm operating from 20 January to 12 February 1533. Delegates from the Poznań and Kalisz regional councils were not elected to this Sejm, which resulted in the refusal of some deputies to take part in the Sejm and their departure from Piotrków. The legitimacy and agency of the deputies’ chamber (and hence the parliament) was questioned in a situation in which the law obtained binding force only upon the consent of all voivodships or lands. The article discusses the method of overcoming the crisis (sessions of the deputy chamber of parliament in a limited composition, and then sending the law passed by the parliament to specially convened parliamentary assemblies for lands that did not adopt parliamentary resolutions). On the basis of previously unknown bills for the payment of flat-rate remuneration for the participation in the work of parliament from the resources of the Central Archives of Historical Records in Warsaw, a list of deputies who participated in the work of the truncated Chamber of Deputies was compiled. Two fragments of bills were also issued in the form of an annex, providing information on payments from the Crown Treasury to senators from the Masovian voivodship taking part in the sessions of the Sejm and delegates of the post-Sejm assemblies who brought to Cracow resolutions adopting the constitutions of the Piotrków Sejm.
