The Tenth Schedule & anti-defection in depth

The constitutional anchor

The anti-defection law was inserted by the Constitution (Fifty-second Amendment) Act, 1985, which added the Tenth Schedule and amended Articles 101, 102, 190 and 191. It was a legislative response to the 'Aaya Ram, Gaya Ram' culture of rampant floor-crossing that destabilised state governments through the 1960s and 1970s — the phrase itself derives from Haryana MLA Gaya Lal, who changed parties thrice in a single day in 1967. The object, as the Statement of Objects and Reasons records, was to curb 'the evil of political defections'.

Grounds for disqualification

The Tenth Schedule disqualifies a member of either House of Parliament or a State Legislature on the following grounds:

• Paragraph 2(1)(a): A member of a political party is disqualified if he voluntarily gives up membership of that party. The Supreme Court in Ravi S. Naik v. Union of India (1994) held that 'voluntarily giving up membership' is wider than formal resignation and can be inferred from conduct.
• Paragraph 2(1)(b): A member is disqualified if he votes or abstains from voting contrary to the party 'whip' (direction), unless condoned by the party within 15 days.
• Paragraph 2(2): An independent member who joins any political party after the election is disqualified.
• Paragraph 2(3): A nominated member is disqualified if he joins any party after six months from taking his seat.

Exceptions and the death of the 'split'

Originally, Paragraph 3 protected a split — if one-third of a legislature party broke away, no disqualification followed. This loophole was repeatedly abused, and the Constitution (Ninety-first Amendment) Act, 2003 deleted Paragraph 3 entirely. After 2003, only a merger under Paragraph 4 is protected: a merger requires that not less than two-thirds of the members of the legislature party agree to merge with another party.

The 91st Amendment also added Article 75(1A) and Article 164(1B), capping the Council of Ministers at 15% of the House strength, and Article 361B, barring a disqualified defector from holding any remunerative political post until re-election. The presiding officer (Speaker or Chairman) is the sole adjudicating authority under Paragraph 6, and Paragraph 7 purported to bar judicial review — a clause struck down as it relates to the constitution amendment process in Kihoto Hollohan.

Kihoto Hollohan: the foundational case

Kihoto Hollohan v. Zachillhu (1992) is the constitutional bedrock. A five-judge bench upheld the validity of the Tenth Schedule but made three decisive holdings. First, it struck down Paragraph 7, which ousted the jurisdiction of courts, because it altered Articles 136, 226 and 227 without ratification by half the states under the proviso to Article 368(2). Second, it held that the Speaker, while deciding disqualification, acts as a Tribunal, and his decision is therefore subject to judicial review — though only on grounds of mala fides, perversity, violation of natural justice, or jurisdictional error, and ordinarily only after a final order, not at an interlocutory stage. Third, it noted the anomaly of the Speaker being a partisan figure adjudicating these disputes.

The problem of delay and the Speaker's discretion

The absence of any time limit in the Tenth Schedule allowed Speakers to sit indefinitely on petitions, letting defectors enjoy office. In Keisham Meghachandra Singh v. Hon'ble Speaker, Manipur Legislative Assembly (2020), the Supreme Court recommended that Parliament reconsider vesting this power in the Speaker and proposed that disqualification petitions be decided within a reasonable period, ordinarily three months, absent exceptional circumstances. In Subhash Desai v. Principal Secretary, Governor of Maharashtra (2023), arising from the Shiv Sena split, the Court reaffirmed that the Speaker must determine the 'real political party' on the basis of the party constitution and leadership structure, not legislative majority.

The whip and 'voluntary' surrender

The whip's writ runs only to votes and motions inside the House; the party structure may discipline members otherwise. G. Viswanathan v. Speaker, Tamil Nadu Legislative Assembly (1996) held that a member expelled by his party remains an 'unattached' member of that party for Tenth Schedule purposes and is still bound by it. Rajendra Singh Rana v. Swami Prasad Maurya (2007) held that the act of supporting a rival's claim to form government can itself amount to voluntarily giving up membership.

The reform debate

The Dinesh Goswami Committee (1990), the Law Commission's 170th Report (1999) and the National Commission to Review the Working of the Constitution (2002) all recommended that the disqualification decision be transferred from the Speaker to the President/Governor acting on the advice of the Election Commission, and that the law apply only to votes determining the survival of a government (confidence motions, money bills). These recommendations remain unimplemented, making them a recurring Mains reform theme.

Why this matters for the exam

The Tenth Schedule is among the highest-yielding micro-topics in UPSC polity, tested in both Prelims GS Paper I and Mains GS-2 ('Parliament and State Legislatures — structure, functioning, conduct of business, powers & privileges').

The Prelims angle

Prelims questions are factual and trap-laden. You must retain, cold: the 52nd Amendment (1985) inserted the Tenth Schedule; the 91st Amendment (2003) deleted the 'split' exception and protected only mergers; the merger threshold is two-thirds, not one-third; the deciding authority is the presiding officer (Speaker/Chairman), not the Election Commission or the courts in the first instance. A favourite trap: whether the anti-defection law applies to the election of the Speaker or to the presidential election — it does not apply to votes where there is no party whip on a constitutional or 'conscience' question in the manner imagined; the whip operates only within the House on party-directed votes. Note also that under Paragraph 5, the Chairman/Speaker is exempted while holding that office.

The Mains angle and PYQ pattern

Mains has repeatedly demanded analytical treatment. The 2022 GS-2 PYQ asked: 'Resorting to ordinances has always raised concern...' — a different topic — but anti-defection appeared in 2013 ('discuss the role of the Speaker') and recurs through editorial-driven questions on whether the Speaker should adjudicate. A strong answer cites Kihoto Hollohan (1992) for judicial review, Keisham Meghachandra (2020) for the three-month timeline, the Dinesh Goswami Committee and 170th Law Commission Report for reform, and concludes with a balanced reform proposal — shifting adjudication to the ECI or an independent tribunal, and restricting the law to no-confidence and money-bill votes to preserve intra-party dissent and deliberative democracy.

High-yield retention list

• 52nd Amendment, 1985 → Tenth Schedule.
• 91st Amendment, 2003 → split deleted; merger (2/3) protected; Art. 75(1A)/164(1B) cap ministry at 15%; Art. 361B.
• Kihoto Hollohan (1992): Para 7 struck down; Speaker = tribunal; review allowed.
• Keisham Meghachandra (2020): three-month norm.
