The Presidium of the Supreme Soviet (Russian: Президиум Верховного Совета, romanized: Prezidium Verkhovnogo Soveta) was the standing organ of the highest body of state authority in the Union of Soviet Socialist Republics (USSR). The presidium was elected by joint session of both houses of the Supreme Soviet to act on its behalf while the Supreme Soviet was not in session. By the 1936 and 1977 Soviet Constitution, the Presidium of the Supreme Soviet served as the collective head of state of the USSR. In all its activities, the Presidium was accountable to the Supreme Soviet of the USSR.
Beside the all-Union body they were also in all union republics (e.g.: Presidium of the Supreme Soviet of the Russian SFSR, Presidium of the Ukrainian SSR, etc.) and other regions including autonomous republics. Structure and functions of the presidiums in these republics were virtually identical.
During discussions in regard to the adoption of the 1936 Constitution of the Soviet Union, on proposition to elect the chairman of the Presidium in a nationwide election, Stalin argued:
According to the system of our Constitution, there must not be an individual President in the U.S.S.R., elected by the whole population on a par with the Supreme Soviet and able to put himself in opposition to the Supreme Soviet. The President of the U.S.S.R. is a collegium, it is the Presidium of the Supreme Soviet, including the President of the Presidium of the Supreme Soviet, elected, not by the whole population but by the Supreme Soviet and accountable to the Supreme Soviet. Historical experience shows that such a structure of the supreme bodies is the most democratic and safeguards the country against undesirable contingencies."
The Presidium of the Supreme Soviet was elected by the Supreme Soviet of the USSR at a joint session of both chambers at the first session of each after convocation. The deputies of the Presidium were appointed for the duration of the term of office of the Supreme Soviet. The Presidium of the Supreme Soviet of the USSR consisted of a chairman, a first vice-chairman (after 1977), his 15 deputies (one from each republic), a secretary, and 20 additional deputies from its two constituent chambers, for a total of 39. The Presidium was accountable to the Supreme Soviet of the USSR for all its activities.
From 1938 to 1989, the chairman of the Presidium was regarded as the USSR/Soviet Union's head of state and was sometimes referred to as the "President of the USSR/Soviet Union" in non-Soviet sources.
Its building, situated inside the Moscow Kremlin, was appropriately named the Kremlin Presidium.
According to the 1936 Constitution of the USSR, as in force as enacted originally (and thus, at the establishment of the Presidium), the basic powers of the Presidium of the Supreme Soviet of the USSR were:
interpretation of current Soviet laws;
dissolution of the Supreme Soviet of the USSR on the basis of Article 47 of the 1936 Constitution of the USSR and scheduling new elections: implementing a national referendum on its own initiative or at the request of one of the republics of the Union.
abrogation of decrees, issued by the Council of Ministers and Council of Ministers of the republics of the Union in case there is a discrepancy with the law;
