The federal structure of the Indian Constitution is unique in its combination of both federal and unitary features. Here’s an analysis of its federal structure, a comparison with the federal systems of the United States, Canada, Australia, and other nations, and an evaluation of the distribution of powers, the role of the center, and the autonomy of the constituent units.

Federal Structure of the Indian Constitution
Key Features
Division of Powers:

The Indian Constitution divides powers between the Union (central government) and the States.
The Seventh Schedule of the Constitution contains three lists:
Union List: Subjects on which only the central government can legislate.
State List: Subjects on which only the state governments can legislate.
Concurrent List: Subjects on which both the central and state governments can legislate, with central law prevailing in case of a conflict.
Supremacy of the Constitution:

The Constitution of India is the supreme law of the land, and any law passed by the central or state governments must conform to it.
Rigid Constitution:

The Constitution provides a rigid amendment process that requires a special majority in Parliament and, in certain cases, ratification by at least half of the state legislatures.
Independent Judiciary:

The Supreme Court of India acts as the guardian of the Constitution and has the power to adjudicate disputes between the center and the states.
Single Citizenship:

India follows the principle of single citizenship, unlike some federal systems where dual citizenship (national and state) is practiced.
Integrated Judiciary:

India has a single integrated judiciary, as opposed to a dual system where federal and state courts are distinct.
Comparison with Other Federal Systems
