Subject Specialist Commentary
Analytical perspective & practical exam advice from the Master10 academic board
Constitutional amendment procedures determine how a country updates its highest legal document. In flexible systems like Britain, lawmakers alter constitutional rules using regular legislative votes. In rigid systems like the United States, amendments require overwhelming supermajorities across national and regional legislatures. India balances both philosophies under Article 368. It allows routine administrative adjustments by simple majority, while safeguarding federal balance through special parliamentary supermajorities and mandatory state ratifications.
For UPSC and State PSC exams, never forget that constitutional amendment bills cannot be resolved through joint sittings under Article 108. Both the Lok Sabha and Rajya Sabha hold equal veto power. A frequent prelims trap tests presidential power: under the 24th Amendment of 1971, the President must grant assent and cannot withhold or return the bill. Remember the federal ratification threshold using the simple fraction "Half of States by Simple Vote."
