How the constitutional arrangements for sharing power work in reality depends to a large extent on how the ruling parties and leaders follow these arrangements?

For a long time, the same party ruled both at the Centre and in most of the States. This meant that the State governments did not exercise their rights as autonomous federal units. As and when the ruling party at the State level was different, the parties that ruled at the Centre tried to undermine the power of the States. In those days, the Central Government would often misuse the Constitution to dismiss the State governments that were controlled by rival parties. This undermined the spirit of federalism.
