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.
The Constitution of India has adopted federal features; though it does not, in fact, claim that it establishes a federation.The question whether the Indian Constitution could be called a federal constitution troubled the minds of the members of the Constituent Assembly.This question cannot be answered without going into the meaning of federalism and the essential features that are evident in federal state.In Indian constitution the powers of state and centre are clearly defined and there are very clear limits of both the centre and the state for law making powers. The State List consists of 66 subjects of local interest such as Public Health, Police etc.The Concurrent List has 47 subjects important to both the Union and the State such as Electricity, Trade Union, Economic and Social Planning, etc.However, this is not applicable in case of Indian States.They have unequal representation in the Rajya Sabha.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.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.
