Frequently Asked Questions

Article 368 lays down the amendment procedure. Three types: (1) Simple majority (by Parliament alone — Article 368 NOT needed): Admission of new states, creation/alteration of state boundaries, citizenship, elections, quorum etc. — these are NOT technically constitutional amendments under Art 368. (2) Special majority (2/3 of members present and voting + majority of total membership of each House): Most constitutional provisions — Fundamental Rights, DPSP, Parliament structure, Supreme Court. (3) Special majority + ratification by at least half of State Legislatures: Federal provisions — Art 368 itself, distribution of powers between Centre and States, representation of states in Parliament, Supreme Court/High Court provisions. Key limitation: Basic Structure Doctrine (Kesavananda Bharati case, 1973) — Parliament cannot amend the 'basic structure' of the Constitution even through Art 368. Basic structure includes: supremacy of Constitution, rule of law, separation of powers, judicial review, federalism, secularism, democracy, fundamental rights.
