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.
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.
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.
The federation is a union because it is indestructible and helps to maintain the unity of the country.
