The 1963 constitution also introduced the concept of rotation, which prohibited remaining at higher or lower level executive positions for more than two four-year mandates.
Public property, self-management and self-organization of working people at the micro and macro level was declared the basis of Economic planning.
The right to social self-management was declared untouchable, and districts in the state (municipality, county, autonomous provinces of Serbia, Socialist Republics and the Federation itself), became socio-political communities.
In the regulation yet unseen in constitutional law, the hierarchy between these units was destroyed and a system of mutual rights and obligations was introduced.
New amendments strengthened the position of autonomous provinces, introduced new areas of self-government and the former federal agencies have become common, instead of remaining superior.
