Anti-Defection Law: Tenth Schedule, Speaker’s Role and Landmark Cases

Quick Answer: The Anti-Defection Law, enacted through the 52nd Constitutional Amendment Act, 1985, inserted the Tenth Schedule into the Constitution to disqualify legislators who defect from their party. Members can be disqualified for voluntarily giving up party membership or voting against the party whip, with the Speaker (or Chairman) as the deciding authority — subject to judicial review.

Background: Why the Anti-Defection Law Was Enacted

Before 1985, Indian politics was plagued by频繁 floor-crossing, memorably described by Deputy Chairman of the Rajya Sabha, H.N. Bahuguna, as the “Aaya Ram Gaya Ram” phenomenon. Legislators switched parties for ministerial berths and money, destabilising governments after almost every election.

Responding to this, Parliament passed the 52nd Constitutional Amendment Act, 1985, which added the Tenth Schedule to the Constitution and amended Articles 102(2) and 191(2) to provide grounds for disqualification of MPs and MLAs on grounds of defection. The law came into effect on 1 March 1985. For the authoritative text, see the Constitution as hosted by the Legislative Department and analysis on PRS Legislative Research.

Tenth Schedule: Key Provisions Explained

The Tenth Schedule contains eight paragraphs. In plain English:

• Paragraph 2(1)(a): Disqualification for voluntarily giving up membership of the political party on whose symbol the member was elected.
• Paragraph 2(1)(b): Disqualification for voting or abstaining in the House contrary to the party’s direction (whip), without prior permission or condonation within 15 days.
• Paragraph 3: The exemption provision — originally covering splits and mergers (discussed below).
• Paragraph 4: Merger exemption — a party may merge with another with the consent of not less than two-thirds of its members.
• Paragraph 6: The Speaker/Chairman is the final deciding authority, and their decision is not liable to judicial review (a clause later read down).
• Paragraph 7: A provision excluding the Schedule’s operation in certain cases — struck down in Kihoto Hollohan (1992).

Grounds for Disqualification Under the Tenth Schedule

Two primary grounds exist under Paragraph 2:

1. Voluntarily giving up party membership: This is wider than formal resignation. The Supreme Court in Ravi Naik vs Union of India (1994) held that even without a resignation letter, conduct demonstrating an intention to resign — such as openly joining another party or campaigning against the parent party — constitutes “voluntarily giving up membership”.
2. Voting or abstaining against the party whip: A member who votes, or abstains from voting, in the House contrary to the direction (whip) issued by the party is disqualified — unless the act was condoned by the party within 15 days or prior permission had been obtained.

Importantly, an independent member who joins a political party after election, and a nominated member who joins a party after six months of taking the seat, also face disqualification.

Exceptions: Mergers and the 91st Amendment, 2003

The 1985 law originally contained two exceptions:

• Split (Paragraph 3): No disqualification if a faction split from the parent party comprising at least one-third of its members. This loophole was infamously exploited — for example, the 11 Shiv Sena MLAs’ split manoeuvres in later decades reignited the debate.
• Merger (Paragraph 4): No disqualification where a party merges with another, provided at least two-thirds of its members agree to the merger.

The 91st Constitutional Amendment Act, 2003 deleted the split exception (Paragraph 3) entirely. Today, only the merger exception survives: a two-thirds approval by members of the legislature party is required, and individual defectors are exempt from disqualification only if the merger conditions are fulfilled. The 2003 amendment also barred defectors from holding ministerial office.

Speaker’s Powers and Role in Deciding Disqualification

Under Paragraph 6, the question of disqualification is decided by the Speaker of the Lok Sabha or State Assembly, or the Chairman of the Rajya Sabha or State Legislative Council, and their decision is “final”.

The Supreme Court has treated this function as essentially administrative or statutory in nature — though in practice the Speaker holds quasi-judicial power. The critical qualification from Kihoto Hollohan (1992) is that the Speaker’s decision is subject to judicial review on the grounds of mala fides, perversity, and violation of natural justice.

Time Limit for Speaker’s Decision: Supreme Court Guidelines

Neither the Constitution nor any statute prescribes a mandatory timeline for the Speaker to decide a disqualification petition. However, in Keisham Meghachandra Singh vs Speaker, Manipur Legislative Assembly (2020), the Supreme Court held that Speakers should decide such petitions within a reasonable time, ideally three months. The Court also suggested Parliament consider enacting a statutory time limit and an independent tribunal for such matters.

Kihoto Hollohan vs Zachillhu (1992): Landmark Judgment

A Constitution Bench in Kihoto Hollohan vs Zachillhu & Others (1992) delivered the definitive ruling on the law’s validity:

• The Tenth Schedule’s validity was upheld — it does not violate free speech under Article 105/194 or any other constitutional provision.
• Paragraph 7 was struck down for not being ratified by half the state legislatures as required under Article 368(2), since it affected the federal structure by excluding state legislators’ rights.
• Paragraph 6’s “finality” clause was read down: the Speaker’s decision is open to judicial review.

Other Important Cases: Ravi Naik, Rajendra Singh Rana, Shrimanth Balasaheb

• Ravi Naik vs Union of India (1994): Broadened “voluntarily giving up membership” to include conduct implying resignation intent, not just a formal letter.
• Rajendra Singh Rana vs Swami Prasad Maurya (2007): The Supreme Court held that the Speaker’s failure to decide a disqualification petition within a reasonable time amounted to constructive rejection, enabling judicial intervention.
• Shrimanth Balasaheb Patil vs Hon’ble Speaker, Karnataka Legislative Assembly (2020): The Court held that the Speaker must decide within three months and that the third-largest party status claimed by defectors (relevant to recognition under the Tenth Schedule and the People’s Representation framework) was a matter for the Election Commission, not a shield against disqualification.

Judicial Review vs Speaker’s Authority: Recent Trends

Indian courts have grown increasingly interventionist where Speakers delay decisions for partisan advantage. In the Maharashtra political crisis (2022-23) — Subhash Desai vs Principal Secretary, Governor of Maharashtra (2023) — the Supreme Court held that the Governor could not call for a floor test based merely on the defection-related resignation of MLAs, and directed the Speaker to decide disqualification petitions within a reasonable time. The trend is clear: courts allow direct High Court challenges to delayed decisions and set judicially supervised deadlines.

Criticisms and Reform Suggestions

• Partisan Speakers: Speakers, usually from the ruling party, are accused of sitting on petitions or deciding them selectively — the “protracted silence” condemned in Rajendra Singh Rana.
• Mergers loophole: Mass defections are legalised by orchestrating a “merger” with two-thirds consent, defeating the law’s spirit.
• No distinction for dissent: Voting against a whip suppresses genuine legislative dissent on conscience issues.
• Dinesh Goswami Committee (1990): Recommended restricting disqualification to voluntarily giving up membership, and that the President/Governor — not the Speaker — decide on advice of the Election Commission.
• 170th Law Commission Report (1999): Suggested decisions on disqualification be made by the President/Governor on the Election Commission’s binding advice, and deletion of the merger exemption.
• 2nd ARC and Election Commission: Both recommended an independent tribunal headed by a retired Supreme Court judge.
