The later Constitution of the SFRY, adopted on 7 April 1963, again provided for republics to "found autonomous provinces in accordance with the constitution in areas with distinctive national characteristics or in areas with other distinguishing features, on the basis of the express will of the population of this area." Within the Socialist Republic of Serbia, "there are the autonomous provinces of Vojvodina and Kosovo and Metohija, established in 1945 by the decision of the People's Assembly of the People's Republic of Serbia in accordance with the express will of the population of these areas." The details of the rights and scope of the provinces was, again, reserved to the republics' constitutions.
