Tenth Schedule (Anti-Defection Law)

The Tenth Schedule of the Constitution of India is the constitutional code that disqualifies members of Parliament and state legislatures for political defection. It was inserted by the Constitution (Fifty-second Amendment) Act, 1985, enacted under Prime Minister Rajiv Gandhi in response to the endemic "Aaya Ram, Gaya Ram" floor-crossing that had destabilised state governments since the fourth general election of 1967. The amendment also altered Articles 102(2) and 191(2) of the Constitution, which list the grounds of disqualification for membership of Parliament and the state legislatures respectively, by cross-referencing the new Schedule. The Schedule was framed to preserve the stability of governments and the integrity of the mandate given to a party by the electorate, subordinating the individual legislator's freedom of conscience to party discipline once elected on a party symbol.

Disqualification under the Tenth Schedule arises in two principal situations, set out in Paragraph 2. First, an elected member of a political party is disqualified if he voluntarily gives up membership of that party—a phrase the Supreme Court has read expansively to include conduct evidencing abandonment of the party even without formal resignation. Second, a member is disqualified if he votes or abstains in the House contrary to a direction (the party whip) issued by his party, unless such conduct is condoned by the party within fifteen days. For a member elected as an independent, joining any political party after the election attracts disqualification; for a nominated member, joining a party after six months of taking the seat does so. The question of disqualification is decided by the presiding officer—the Speaker or Chairman of the relevant House—whose decision was originally made final and non-justiciable by Paragraph 7.

The Schedule originally contained two protective exemptions in Paragraph 3 and Paragraph 4. Paragraph 4 exempts a merger, deeming it valid where not less than two-thirds of the legislature party agrees to merge with another party. Paragraph 3 had exempted a "split" where one-third of the party broke away, but this loophole was deleted entirely by the Constitution (Ninety-first Amendment) Act, 2003, after the split provision had been repeatedly exploited to engineer mass defections. The 2003 amendment also barred defectors from holding any office of profit, such as a ministerial or remunerative political post, until they are re-elected. A further procedural safeguard provides that disqualification proceedings are governed by rules each House frames, and that the Speaker acts in a quasi-judicial capacity bound by the principles of natural justice.

Contemporary practice has revealed the Schedule's structural weakness: the absence of any time limit on the Speaker's decision. In Karnataka in July 2019, Speaker K. R. Ramesh Kumar disqualified seventeen Congress and Janata Dal (Secular) MLAs whose resignations precipitated the fall of the H. D. Kumaraswamy coalition government, a sequence the Supreme Court examined in Shrimanth Balasaheb Patil v. Speaker, Karnataka Legislative Assembly (2019). In Maharashtra, the Shiv Sena split of June 2022 led by Eknath Shinde produced protracted proceedings before Speaker Rahul Narwekar, who in January 2024 declined to disqualify the Shinde faction's MLAs after the Supreme Court in Subhash Desai v. Principal Secretary, Governor of Maharashtra (2023) directed an expeditious decision. Similar disputes have arisen in Madhya Pradesh (2020) and Rajasthan (2020).

The Tenth Schedule is distinct from a motion of no confidence, with which it is frequently confused: a no-confidence motion tests whether a government retains the assembly's majority and is decided by a vote of the whole House, whereas anti-defection disqualification is an individual penalty imposed on a member for breaching party discipline. It is also distinct from a recall, which does not exist in Indian law, and from the ordinary disqualifications under Articles 102(1) and 191(1) (office of profit, unsound mind, insolvency, foreign citizenship), which are decided by the President or Governor on the Election Commission's opinion rather than by the Speaker.

The most significant judicial intervention is Kihoto Hollohan v. Zachillhu (1992), in which a constitution bench struck down Paragraph 7's bar on judicial review as unconstitutional for failing to secure ratification by the states under the proviso to Article 368(2), while upholding the rest of the Schedule; the Court held the Speaker's decision is subject to judicial review on grounds of mala fides, perversity and violation of natural justice, though only after the order is passed. In Rajendra Singh Rana (2007) and Nabam Rebia (2016) the Court further constrained the office. The recurring controversy is the partisanship of the Speaker, who belongs to the ruling party, and the indefinite delay in deciding petitions; in Keisham Meghachandra Singh v. Speaker, Manipur (2020) the Court recommended that Parliament consider transferring the adjudicatory function to an independent tribunal and suggested a reasonable period of roughly three months for decisions.

For the working practitioner, the Tenth Schedule is the principal legal instrument governing the survival of coalition and minority governments in India, and a frequent flashpoint between the legislature and the judiciary over the finality of the Speaker's writ. Desk officers, journalists and policy researchers tracking government formation must distinguish a genuine two-thirds merger under Paragraph 4 from an engineered mass resignation designed to reduce the assembly's effective strength and thereby lower the majority threshold. The Schedule remains a live reform agenda, with the Law Commission, the National Commission to Review the Working of the Constitution (2002) and successive Supreme Court benches recommending independent adjudication and statutory deadlines that Parliament has yet to enact.
