Amendment Procedure — Basic Structure

Updated 5 Mar 2026

Basic Structure

The constitutional amendment procedure in India, governed by Article 368, provides three distinct methods for changing the Constitution based on the provision's significance. Simple majority amendments apply to administrative matters like citizenship and legislative councils, requiring only basic parliamentary approval.

Special majority amendments, needing majority of total membership and two-thirds of present members in both Houses, cover most constitutional provisions including fundamental rights and institutional structures.

Special majority plus state ratification applies to federal matters like presidential elections, power distribution, and parliamentary representation, requiring additional approval from half the state legislatures.

The procedure reflects the Constitution's balanced approach—neither too rigid like the USA nor too flexible like the UK. Key safeguards include the basic structure doctrine from Kesavananda Bharati (1973), which prevents amendments from destroying core constitutional principles like democracy, federalism, and judicial review.

Parliament's constituent power is plenary but not unlimited, subject to judicial review for basic structure violations. The President's assent is mandatory for constitutional amendments, unlike ordinary legislation.

With 105 amendments since 1950, India demonstrates constitutional adaptability while maintaining stability through graduated amendment procedures and judicial oversight.

Joint SittingNot applicable - both Houses must pass separatelyPossible under Article 108 for deadlocks
Presidential AssentMandatory - President cannot withholdDiscretionary - can return for reconsideration
Judicial ReviewSubject to basic structure doctrineFull judicial review for constitutional validity

Constitutional amendments operate under Parliament's constituent power with stricter procedural requirements and mandatory presidential assent, while ordinary legislation uses legislative power with more flexible procedures and discretionary presidential powers.

The amendment procedure's graduated difficulty and basic structure limitations distinguish it fundamentally from ordinary lawmaking, reflecting the Constitution's supreme status and the need for broader consensus in constitutional change.

Why it is tested: UPSC frequently tests the distinction between constituent and legislative powers, procedural differences, and the implications of these differences for parliamentary functioning and constitutional governance.

AspectAmendment ProcedureAmendment Procedures in USA
InitiationEither House of Parliament2/3 majority in both Houses of Congress or Constitutional Convention
Federal RatificationRequired for specific provisions onlyRequired for all amendments (3/4 of states)
Judicial ReviewBasic structure doctrine limits amendmentsNo judicial review of amendment content

FlexibilityGraduated procedure based on provision typeUniform rigid procedure for all amendments

India's amendment procedure is significantly more flexible than the USA's rigid system, allowing for constitutional adaptation while maintaining federal safeguards for specific provisions. The basic structure doctrine provides judicial oversight absent in the US system, while India's graduated approach contrasts with America's uniform rigidity. This difference explains India's higher amendment frequency and greater constitutional adaptability to changing circumstances.

Why it is tested: Comparative constitutional analysis is crucial for UPSC, testing understanding of different federal models, constitutional rigidity vs. flexibility, and the role of judicial review in constitutional change.
