Radom Constitution of 1505

a statute adopted by the Polish Sejm in the city of Radom.

The Radom Constitution, also called from its first words the Nihil Novi Constitution, stipulated that the king could make no law without the consent of the Senate and the szlachta’s Chamber of Deputies. The constitution also called for “general agreement” in the Sejm, a provision that was later interpreted by the nobility as a requirement for unanimity in the Sejm and as a sanction for the liberum veto. The adoption of the Radom Constitution completed the development of the Polish Sejm as the highest legislative body, within which the decisive voice belonged to the szlachta’s Chamber of Deputies.
