Federalism and the Basic Structure Doctrine

Federalism constitutionally divides governmental powers between the Union and the States, each operating within its assigned sphere. In India, it creates meaningful State-level arenas of government and political competition. It forms part of the basic structure, so Parliament may amend federal provisions but cannot destroy the Constitution's federal character.

Federal design of the Constitution

The written and supreme Constitution establishes Union and State governments and protects their respective authority.

• Article 1 describes India as a Union of States, recognising States as constituent units of the constitutional system.
• Article 246 and the Seventh Schedule distribute legislative subjects through the Union, State and Concurrent Lists.
• The Rajya Sabha represents States at the Union level, while Article 131 gives the Supreme Court original jurisdiction over specified Union-State disputes.
• Under Article 368, amendments affecting specified federal provisions require ratification by at least one-half of the State legislatures.

Political space for State-level parties

Because States possess constitutionally assigned legislative and executive responsibilities, elections to State legislatures determine control over significant areas of public policy. This gives State-level parties an institutional arena in which regional aspirations can be converted into representation and government.

• Parties can mobilise voters around State-specific concerns such as language, identity, development priorities and regional interests.
• A party with sufficient legislative support can form a State government and pursue policies within the State's constitutional sphere.
• Strength in State legislatures can provide representation in the Rajya Sabha and bargaining influence in Union-level coalitions and intergovernmental politics.

Basic-structure protection and its limits

Federalism prevents complete concentration of authority at one level while accommodating India's diversity and national unity. Its protection preserves the institutional space within which State politics operates, but does not guarantee the electoral success of any party.

• In Kesavananda Bharati v. State of Kerala, 1973, the Supreme Court held that Parliament cannot alter the Constitution's basic structure through amendment.
• In S.R. Bommai v. Union of India, 1994, the Court affirmed federalism as a basic feature while examining the use of Article 356.
• Basic-structure protection does not freeze every federal provision; it prevents amendments that abrogate or substantially damage the federal balance.
• The doctrine limits Parliament's constituent power under Article 368; ordinary laws and executive actions remain subject to constitutional provisions and judicial review.
