Constitution (91st Amendment) Act 2003

The Constitution (91st Amendment) Act 2003 is a landmark amendment that inserted Articles 75(1A) and 164(1A) into the Indian Constitution, expressly limiting the size of the Union and State Councils of Ministers to no more than fifteen percent of the total strength of the respective legislatures. By converting a long‑standing political convention into a constitutional rule, the amendment sought to curb the proliferation of ministries, reduce fiscal burdens, and promote more accountable governance.

Historical Background

The push for a statutory cap emerged in the 1990s when several states, notably Uttar Pradesh and Karnataka, expanded their cabinets to accommodate coalition partners and regional factions. Public criticism intensified after the 1994 Supreme Court observation in M. P. Singh v. Union of India that an excessively large ministry could undermine the principle of collective responsibility, although the Court stopped short of imposing a numerical limit. The issue resurfaced after the 1999‑2000 coalition era, prompting the Law Ministry under Arun Jaitley to draft a constitutional solution. The amendment was introduced in Parliament on 20 July 2003, passed by a special majority in both Houses on 20 August 2003, and received the President’s assent the same day, coming into force immediately.

Constitutional Mechanism

Article 75(1A) states that “the total number of Ministers, including the Prime Minister, shall not exceed fifteen percent of the total number of members of the House of the People.” A similar provision appears in Article 164(1A) for State legislatures, with a proviso that a state having a Legislative Council may exceed the limit by up to two Ministers, provided the total does not surpass fifteen percent of the Assembly strength. The amendment also empowers the President and Governors to dismiss any Minister appointed in excess of the prescribed ceiling, thereby giving the limit enforceable legal force rather than a mere political guideline.

Key Provisions

• •Article 75(1A) – Caps Union ministers at 15 % of Lok Sabha members (currently 543, allowing a maximum of 81 ministers).
• •Article 164(1A) – Caps State ministers at 15 % of the Legislative Assembly strength (e.g., a 403‑member Assembly in Uttar Pradesh permits up to 60 ministers).
• •Proviso for bicameral states – Allows up to two additional ministers beyond the 15 % ceiling if the state has a Legislative Council, reflecting the need for representation from both houses.
• •Enforcement clause – Grants the President and Governors authority to refuse or withdraw a ministerial appointment that breaches the limit, making compliance a constitutional requirement.

Implementation and Impact

Following the amendment, several states undertook cabinet downsizing. Karnataka reduced its ministry from 55 to 44 members in 2004, while Uttar Pradesh trimmed its council from 73 to 53 ministers the same year. At the Union level, the first post‑amendment
