It proclaimed the USSR to be a federation of eleven Soviet Republics. The All-Russian Congress of Soviets was replaced by a new 'Supreme Soviet' made up of the Soviet of the Union and the Soviet of Nationalities. Each republic also had its own supreme soviet.
The new constitution promised local autonomy to ethnic groups and support for national cultures and languages. It also promised four-yearly elections with the right to vote for all over eighteens including the 'former people' who had previously been deprived of voting rights.
It was accompanied by an extensive statement of civil rights - such as freedom from arbitrary arrest and the right to free speech. The new constitution did, indeed, look democratic and its main intention may have been to impress foreigners.
In practice, the promised rights were largely ignored, and the central control exercised over the republics' budgets ensured the primacy of union laws and little real regional independence.
Although the constitution acknowledged the right of any union republic to leave the union, when Party leaders in Georgia allegedly planned secession in 1951, they were purged.
Elections were not contested so that the right to vote was merely to affirm a choice of representative and only approved party members names were on the ballot papers.
Supreme Soviet economy met a few days twice a year. It provided more sense of participation rather than actual involvement. It was viewed by the Party as a forum for imparting decisions back to the localities rather than for electors to present their views to the centre.
