  • Each House separately; no joint sitting.
  • President must assent (24th Amendment, 1971).

High-yield facts
  • Amendment procedure borrowed from South Africa.
  • Ratification: half the States, simple majority, no time limit.
  • Kihoto Hollohan (1992) struck down para 7 of the Tenth Schedule because it lacked State ratification.
  • The basic structure has no exhaustive list — it grows case by case.

Traps

Common confusions
  • Creating a new State or a Legislative Council needs only a simple majority — and is not an Article 368 amendment.
  • Fundamental Rights need a special majority, not State ratification.
  • Amendment Bill numbers differ from amendment Act numbers.
