On January 6, 1929 King Alexander abolished the St Vitus's Day Constitution, dissolved the National Assembly and imposed his own regime. The Government adopted a number of laws that replaced the legal norms from the abolished Constitution. Under the Law on the Royal Power and the Supreme Administration of the State, the Kingdom of Serbs, Croats and Slovenes was defined as a hereditary monarchy. It was declared that all authority in the country was vested in the king. He appointed the president and members of the Ministerial Council who worked under his authority. He issued and promulgated laws through decrees previously signed by the prime minister, competent minister and justice minister. The judiciary operated in the name of the king.
Under the Law on the Protection of Public Security and Order in the State, the public and political lives were suspended and the work of associations and political parties "that bear religious or tribal markings" was banned. Under the Law Amending the Law on Municipalities and Regional Governments, municipal administrations were dissolved and it was said that municipal administrations for the cities of Belgrade, Zagreb and Ljubljana would be appointed under a king's decree and that grand chieftains would appoint the other municipal administrations.
