The Supreme Soviet had authority to: • Enact laws and amend the
Constitution of the Soviet Union. • Elect the
Presidium of the Supreme Soviet, which acted as a collective head of state between sessions. • Appoint the
Council of Ministers (executive branch). • Ratify international treaties and approve economic plans. Sessions were generally short, held twice a year, with most legislative work done by standing commissions or the Presidium. Between sessions, its powers were exercised by the
Presidium of the Supreme Soviet, which could issue decrees (
ukazy) with the force of law, subject to later approval. In 1988, the constitution was amended to create a new body, the
Congress of People's Deputies, with many of the powers formerly assigned to the Supreme Soviet. The Congress also served as an
electoral college with the duty to elect the Supreme Soviet, which accordingly became a subsidiary of the new body, in a relationship somewhat similar to the Supreme Soviet's own relationship with its Presidium. By 1989, its powers were: • Passing and initiating laws. • Submitting questions to the
President of the Soviet Union, the
Council of Ministers of the Soviet Union, scheduling elections of deputies. • Convening the
Congress of People's Deputies. • Appointing the
Chairman of the Council of Ministers on the submission of the President. • Ratifying the composition of the Council of Ministers and changes in it on the submission on the Chairman. • Forming and disbanding ministries and state committees on the proposal of the Council of Ministers. • Overriding a presidential veto with a two-thirds majority. • Ratifying presidential declarations of war. • Impeaching the President. • Hearing reports by organs of appointed officials. • Implementing laws regulating property, management of the economy, social and cultural issues, budget and finance, salaries, prices, taxes, environmental protection, natural resource, and civil rights, • Laying down the principals of local and republic state power and the legal status of social organisations, • Submitting for ratification (and ratifying and amending) by the congress long-term national and social and economic development plans, the national budget, monitoring implantation of the state plan and budget, and ratifying reports on their performance. • Ratifying international treaties. • Overseeing the granting of foreign aid and negotiating foreign loans. • Determining basic measures for national security, including declarations of war, mobilizing troops, and meeting international treaty obligations. Acts by the Supreme Soviet entered into force after signature by the President and their subsequent publication. Between 1938 and February 1990, more than 50 years, only 80 laws were passed by the Supreme Soviet, less than 1% of total legislative acts. == Leaders ==
