As a result of the Treaty of Vis, AVNOJ was reformed into the Temporary National Assembly which also included several dozen members of the assembly elected in 1938. After the consolidation of power by the communists in late 1945, the Constitutional Assembly was established. The Constitutional Assembly was divided into two houses: the Federal Assembly, and the Assembly of Peoples.
With the adoption of a constitution in 1946, the name National Assembly was adopted again. It was divided into two councils (chambers):[1] the Federal Council, and the Council of Peoples.[2] With the amendment of the constitution in 1953, the Federal People's Assembly was divided into the Federal Council and the Council of Producers (from 1953 until 1967 the Council of Nations was a "sub-chamber" within the Federal Council).
In 1963 with the adoption of a new constitution, the Federal Assembly was divided into five chambers: the Federal Council, the Economic Council, Educational-Cultural Council, Social-Health Council and the Organization-Political Council.[3] In 1967 the Council of Nations became it separate chamber, while in 1968 the Federal Council was demoted in favor of the Council of Nations and the Organization-Political Council changed its name into Socio-Political Council. The Federal Assembly of Yugoslavia was the only pentacameral (later hexacameral) legislature in political history.[4]
After the 1974 Yugoslav Constitution was adopted, the Assembly of the SFRY was bicameral, with the lower house called the Federal Chamber and an upper house called the Chamber of Republics and Provinces. The Federal Chamber had 30 members from each Republic and 20 from each Autonomous Province, while the Chamber of Republics and Provinces had 12 members from each Republic and 8 from each Autonomous Province. The Assembly was composed of members of the League of Communists from each constituent republic appointed by electoral colleges chosen at different levels in the legal hierarchy through complex procedures.[5]
When the League of Communists collapsed in 1990 amid ethnic tensions, the Assembly was shut down. The institution would be resurrected as the Federal Assembly of the Federal Republic of Yugoslavia in 1992, but this assembly had elected members.
