In a true federation such as that of United State of America every State irrespective of their size in terms of area or population it sends two representatives in the upper House i.e. In addition to all this, all important appointments such as the Chief Election Commissioner, the Comptroller and Auditor General are made by the Union Government. There is no provision for separate Constitutions for the states.
Such an amendment has to be passed by majority of total members of each house of the Parliament as well as by two-thirds majority of the members present and voting there in.
However, in addition to this process, some amendments must be approved by at least 50% of the states.
The procedure of amending the Constitution in a federal system is normally rigid.
Indian Constitution provides that some amendments require a special majority.
In other words, Governor is the agent of the Centre in the States.
The working of Indian federal system clearly reveals that the Governor has acted more as centre’s representative than as the head of the State.A unitary system is governed constitutionally as one single unit, with one constitutionally created legislature. A unitary state is a sovereign state governed as one single unit in which the central government is supreme and any administrative divisions (sub national units) exercise only powers that the central government chooses to delegate.This is one of the federal features of the Indian constitution.It has been the matter of debate among the scholars that whether the constitution of India is completely federal or unitary in nature.But actually Indian constitution contains both features of a federal constitution and unitary constitution.The supremacy of the constitution means that both, the Union and the State Governments, shall operate within the limits set by the Constitution.
