But for the very clear picture of this conclusion first of all we have to know that what is the federal constitution and what is unitary constitution.
What feature of Indian constitution makes it federal or what features makes it unitary.
Supremacy of judiciary is another very important feature of a federal state where there is an independent judiciary to interpret the Constitution and to maintain its sanctity.
The Supreme Court of India has the original jurisdiction to settle disputes between the Union and the States.
Besides, the Constitution of the Union and the States is a single framework from which neither can get out and within which they must function.
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.
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.
The States cannot propose amendments to, the Constitution.
