What can be the minimum strength of Council of Ministers including Chief Minister in the States?
- (a)10
- (b)12
- (c)13
- (d)14
Correct — B, 12. Article 164(1A) of the Constitution provides that 'the total number of Ministers, including the Chief Minister, in the Council of Ministers in a State shall not be less than twelve.' This floor was inserted by the 91st Constitutional Amendment Act, 2003 (the same clause also caps the Council at 15% of the total members of the Legislative Assembly). So even a small State cannot have fewer than 12 ministers including the Chief Minister — making 12 the minimum.
- (a)10 — Wrong — the constitutional floor is twelve, not ten; Article 164(1A) fixes the minimum at 12.
- (c)13 — Wrong — 13 is above the prescribed minimum. The Constitution sets the floor at 12, not 13.
- (d)14 — Wrong — 14 exceeds the minimum. The 91st Amendment fixed the lower limit at 12.
The 91st Constitutional Amendment Act, 2003 added Article 164(1A) for States (and Article 75(1A) for the Union) to control 'jumbo' ministries and defection-driven reward-giving. For States it set both a ceiling and a floor: the Council of Ministers, including the Chief Minister, must not exceed 15% of the total strength of the Legislative Assembly, and must not be fewer than 12. The 12-minister floor protects small States/UTs whose 15% ceiling would otherwise be tiny.
The question tests the lower limit, not the 15% ceiling. Note the floor applies to the Council 'including the Chief Minister'. The number 12 comes straight from Article 164(1A) — the same reform that also fixed the 15% cap most students remember for the ceiling side.
- Article 164(1A): State Council of Ministers (incl. CM) shall not be less than 12
- Same clause caps the Council at 15% of the Legislative Assembly's total strength
- Both limits were inserted by the 91st Constitutional Amendment Act, 2003
- The parallel Union provision is Article 75(1A) — 15% of the Lok Sabha's strength

- Confusing the 12-minister floor (Art 164(1A)) with the 15% ceiling of the same clause
- Applying the Union figures (Lok Sabha) to a question that is specifically about the States
UPPSC/UPSC ask either for the minimum (12) or for the 15% ceiling, and often for the amendment that introduced both (91st).
Which of the Constitution Amendment Acts seeks that the size of the Council of Ministers at the Centre and in a State must not exceed 15 percent of the total number in the Lok Sabha and the total number of members of the Legislative Assembly of that State, respectively?
- (a) 91st
- (b) 93rd
- (c) 95th
- (d) 97th
Answer(a) 91st
Same provision — Article 164(1A) for States (and 75(1A) for the Union), inserted by the 91st Amendment. UPSC 2007 tests the amendment/15% ceiling; this 2020 question tests the 12-minister floor of the very same clause.
Which one of the following Constitutional Amendments states that the total number of Ministers, including the Prime Minister, in the Council of Ministers shall not exceed fifteen percent of the total number of members of the House of the People ?
- (a) 90th
- (b) 91st
- (c) 92nd
- (d) 93rd
Answer(b) 91st
Same 91st-Amendment reform on ministry size — UPSC 2009 asks the Union side (Art 75(1A), 15% of Lok Sabha); this UPPSC 2020 item asks the State-side minimum (Art 164(1A), not less than 12).
