Two characteristics of Indian independence Act, 1947:
1. The foundation of two dominion states:
This Act had a provision that India would be partitioned and so two dominions India and Pakistan would be formed.
2. An end of British supremacy over princely states:
With the formation of these dominions, the British supremacy would end over the princely states and all the treaties and agreements between them would automatically stand void. The states would be free to join either India or Pakistan, or to remain independent.
