The underlying idea of the doctrine of separation of power is that the organs of the government do not overlap or interchange the functions that are exercised by them individually. The notion of ‘separation of powers' is the division of authorities and duties among the legislative, executive, and judicial branches. The power and accountability are being divided among these three organs of Indian government, viz., judiciary, legislature and executive. This doctrine makes sure that there is no amalgamation of power. This paper attempt to analyze the concept of this doctrine in India, the objective, criticism and how it is a barrier to administrative law.
