Anti-Defection Law (Tenth Schedule): 52nd Amendment, Grounds, Recent Rulings

The Anti-Defection Law is the constitutional answer to the politics of “Aaya Ram, Gaya Ram” — the floor-crossing culture that destabilised Indian legislatures through the 1960s and 1970s. Enacted as the Tenth Schedule through the 52nd Constitutional Amendment in 1985, the Anti-Defection Law disqualifies legislators who defect from the party on whose ticket they were elected. It applies to both Parliament and State Legislatures and is adjudicated by the Speaker of the House (or Chairman in the case of Rajya Sabha and Legislative Councils). The 91st Amendment of 2003 tightened the law by removing the one-third “split” exception that had allowed mass defections.

For UPSC Polity, the Anti-Defection Law is one of the most-asked topics. It sits at the intersection of party discipline, individual conscience, the Speaker’s neutrality, and the judiciary’s growing role through cases like Kihoto Hollohan, Keisham Meghachandra Singh, and the recent Maharashtra and Karnataka disqualification rulings. This guide walks through the structure, grounds, exceptions, Speaker’s role, and current controversies.

Origin: Why the Anti-Defection Law Exists

Through the late 1960s and 1970s, frequent floor-crossing by legislators — for ministerial offices, money, or post-election bargaining — brought down state governments and produced the famous “Aaya Ram, Gaya Ram” headline (after Gaya Lal, the Haryana MLA who changed parties three times in a single day in 1967). Between 1967 and 1971, 142 defections in Parliament and 1,969 defections in state legislatures were documented.

The Y.B. Chavan Committee (1968) recommended a constitutional remedy. After several false starts, the Rajiv Gandhi government enacted the 52nd Constitutional Amendment in 1985, inserting the Tenth Schedule. It came into force on 1 March 1985.

Structure of the Tenth Schedule

The Tenth Schedule has eight paragraphs. The core machinery sits in Paragraphs 2, 3, 4, 6, and 7.

Paragraph 2: Grounds for Disqualification

A member is disqualified if:

For a member belonging to a political party:

• Voluntarily gives up membership of the political party on whose ticket they were elected.
• Votes or abstains in the House contrary to any direction (whip) issued by the political party — unless the party condones the vote/abstention within 15 days.

For an independent member:

• Joins any political party after election.

For a nominated member (in Rajya Sabha or Legislative Council):

• Joins any political party after the expiry of six months from the date of taking their seat. (Nominated members can choose a party within the first six months without consequence.)

“Voluntarily Giving Up” — Wider Than Resignation

The Supreme Court has read “voluntarily giving up membership” much wider than formal resignation. In Ravi S. Naik v. Union of India (1994), the Court held that conduct inferring a giving-up — attending rival party rallies, publicly opposing the party, contesting against the party — can count. Resignation is not required; behaviour is enough.

Exceptions

Two exceptions survive after the 91st Amendment:

Merger (Paragraph 4)

If two-thirds or more of the members of the original political party in the House agree to a merger with another party, neither the members who merge nor those who remain with the original party are disqualified. This is the only intact exception today and the one that drives most modern “defection by merger” cases.

Office of Speaker/Chairman (Paragraph 5)

If a member, on being elected as Speaker or Chairman, voluntarily gives up party membership to maintain neutrality, they are not disqualified. They may rejoin the party after ceasing to hold that office.

The Deleted “Split” Exception

The original Tenth Schedule allowed a one-third split — if at least one-third of the legislature party broke away, they were not disqualified. This produced the era of “engineered splits” — Karnataka 1985, UP 1997, Goa 2002. The 91st Constitutional Amendment in 2003 deleted Paragraph 3 and removed the split exception entirely. Today, only a two-thirds merger saves a defecting bloc.

91st Amendment 2003

The 91st Amendment did three things:

1. Deleted the 1/3 split exception — only mergers now save legislators.
2. Capped the size of the Council of Ministers at 15% of the strength of the Lok Sabha or State Legislative Assembly (Article 75(1A) and 164(1A)).
3. A defector cannot hold any ministerial or remunerative political post until re-elected or until the end of the original term.

These three changes together broke the most common defection incentive — ministerial reward.

Speaker’s Role — and the Bias Problem

Under Paragraph 6 of the Tenth Schedule, the Speaker of the House (or Chairman) is the sole authority to decide disqualification petitions. Their decision is final and was originally intended to be insulated from judicial review.

Kihoto Hollohan (1992)

In Kihoto Hollohan v. Zachillhu (1992), a five-judge Constitution Bench held that:

• Paragraph 7 of the Tenth Schedule (which barred judicial review entirely) was struck down for not being passed with the required ratification under Article 368(2).
• The Speaker’s decision is subject to judicial review on grounds of mala fide, perversity, violation of constitutional mandate, and non-compliance with rules of natural justice.
• But judicial review can come only after the Speaker has decided — courts cannot interfere mid-stream.

The Bias Concern

The Speaker is usually elected from the ruling party — the same party that benefits from delayed or selective disqualification decisions. This produces a structural conflict of interest. The Supreme Court has repeatedly flagged this. In Keisham Meghachandra Singh v. Speaker, Manipur Legislative Assembly (2020), the Court observed that the Speaker, in deciding disqualification, acts as a tribunal and should be replaced by an independent permanent tribunal headed by a retired Supreme Court judge — a suggestion that requires a constitutional amendment.

The Two-Month Deadline — Keisham Meghachandra (2020)

In Keisham Meghachandra Singh (2020), the Supreme Court issued a landmark direction: Speakers should ordinarily decide disqualification petitions within three months (reduced to a reasonable period, typically not exceeding three months, often summarised as a “two-to-three-month” deadline). Sitting on petitions indefinitely was held to defeat the purpose of the Tenth Schedule.

The Court reiterated this in Subhash Desai v. Principal Secretary, Governor of Maharashtra (2023). The Speaker’s inaction on defection petitions remains a live issue.

Recent Rulings: Maharashtra and Karnataka

Maharashtra (Shiv Sena Split, 2022–24)

The Eknath Shinde faction of 39 Shiv Sena MLAs claimed they were the “real Shiv Sena”. The Speaker, Rahul Narwekar, ruled in favour of Shinde in January 2024 — not disqualifying them and recognising their faction as the original party. The Supreme Court in Subhash Desai had already laid down that the Speaker should determine the “real political party” using the constitution of the political party, not the legislature party majority — but the Speaker’s actual decision was based largely on legislative strength, which is now under judicial challenge.

Karnataka (2019)

The disqualification of 17 Congress-JD(S) MLAs by Speaker K.R. Ramesh Kumar in 2019, and the Supreme Court’s partial overturning (allowing them to contest by-elections), produced one of the clearest reaffirmations that the Speaker cannot bar a disqualified member from contesting again.

Manipur (Keisham Meghachandra, 2020)

The Manipur Speaker’s two-year delay on a disqualification petition against a defected Congress MLA-turned-minister provoked the Keisham Meghachandra direction on the three-month deadline.

Limits and Critiques

The Anti-Defection Law has been criticised on several fronts:

• Kills internal dissent: a member cannot vote conscience without risking disqualification.
• Speaker’s bias: ruling-party Speakers tend to favour their side.
• Delay: the three-month deadline is not always honoured.
• Merger exception: the two-thirds threshold has become the new engineering target — splits are now staged as mergers.
• Doesn’t cover pre-poll defections: legislators can defect before re-election or use Rajya Sabha resignation-and-recontest manoeuvres.

The Dinesh Goswami Committee (1990), the Law Commission’s 170th Report (1999), and the NCRWC (2002) have all recommended that disqualification should be limited to whip violations on confidence motions and money bills only — leaving all other votes to conscience. None of these proposals has become law.

Procedure for Disqualification

A typical disqualification proceeding:

1. A petition is filed with the Speaker by any member of the House (usually from the affected party).
2. The Speaker issues notice to the respondent member, who files a reply.
3. Oral hearings, witness examinations, and document review follow.
4. The Speaker decides — disqualifying or rejecting the petition.
5. The aggrieved party can move the High Court under Article 226 or the Supreme Court under Article 32 for judicial review.

The Speaker’s order is subject to Kihoto Hollohan review standards but not appealable as a matter of right.
