Following are the two faults of the power – separation theory:
1. It is an undemocratic theory:
The concept of welfare state is becoming powerful on account of the development of democratic views. The functions of the government have increased and the expectations of people have also increased. The legislature represents people’s will. Under these circumstances, the executive lays emphasis on welfare of the people. In doing so, some representatives may feel offended when they are not able to control the executive effectively, and the basic principles of democracy are destroyed.
2. Confrontation among various organs of the government:
Power – separation theory may create rivalry among the three organs of the government and an internal struggle may arise. So, for proper functioning of the government, spirit of co – ordination, balance and co-operation is essential.
