Supreme Court flags 'enormous issues' with anti-defection law, issues notice on Kapil Sibal's plea
The Supreme Court issued notice to the Union Government on a petition challenging the prevailing interpretation of the "merger" exception under the Tenth Schedule of the Constitution (the anti-defection law).
The petition argues that legislators who move from the party on whose ticket they were elected to another party are being shielded from disqualification by invoking the merger provision, even in situations where a genuine merger of the original political party has not occurred.
The bench observed that the anti-defection framework has "enormous issues," but noted that resolving gaps in the legislative design of the Tenth Schedule is primarily a task for Parliament, since the provisions were framed by lawmakers themselves.
The Court did not stay any pending disqualification proceedings; it has sought the Centre's response on the interpretation question before proceeding further.
The Tenth Schedule and the 52nd Amendment Act, 1985
The Tenth Schedule was inserted into the Constitution by the Constitution (Fifty-Second Amendment) Act, 1985, to check the "evil of political defections" that had destabilised state governments after the 1967 general elections (the "Aaya Ram Gaya Ram" phenomenon). It lays down the grounds on which an elected member of Parliament or a State Legislature can be disqualified for defection.
Key Details
- Paragraph 2 disqualifies a member who voluntarily gives up membership of their political party, or who votes/abstains contrary to a party whip without prior permission (and without condonation within 15 days).
- Paragraph 4 is the "merger" exception: disqualification does not apply where the original political party merges with another party, provided not less than two-thirds of the members of the legislature party concerned have agreed to the merger.
- Paragraph 3, which had earlier exempted a "split" in a party where at least one-third of members broke away, was deleted by the Constitution (Ninety-First Amendment) Act, 2003 — leaving the merger exception as the sole surviving escape route from disqualification.
- Paragraph 6 designates the Speaker (or Chairman, in the case of the Rajya Sabha/Legislative Council) as the adjudicating authority on disqualification petitions.
The present plea targets Paragraph 4 specifically, arguing that the two-thirds "legislature party" threshold is being treated as sufficient on its own, without verifying that the original political party itself has genuinely merged — the twin conditions Paragraph 4 was designed to require together.
Kihoto Hollohan v. Zachillhu (1992) — Judicial Review of the Speaker's Decision
This five-judge Constitution Bench of the Supreme Court is the foundational precedent on the Tenth Schedule. It upheld the constitutional validity of the anti-defection law but struck down Paragraph 7, which had sought to bar all courts from reviewing the Speaker's disqualification decisions.
Key Details
- By a 3:2 majority, the Court held that Paragraph 7's exclusion of judicial review violated the basic structure of the Constitution, since it was not ratified by state legislatures as required for amendments affecting Article 136/226/227 jurisdiction.
- The Speaker/Chairman, while acting as adjudicator under the Tenth Schedule, functions as a tribunal and is subject to judicial review, though only on limited grounds such as mala fide exercise of power, perversity, or violation of natural justice — not on the merits at large.
- In Keisham Meghachandra Singh v. Hon'ble Speaker, Manipur Legislative Assembly (2020), the Supreme Court directed that Speakers must ordinarily decide disqualification petitions within three months, and suggested that Parliament consider replacing the Speaker with an independent tribunal (headed by a retired judge) as the primary adjudicator, to remove the conflict of interest inherent in a party-affiliated Speaker deciding defection cases.
The current plea builds on this line of criticism — that the Tenth Schedule's design (both the merger loophole and Speaker-as-adjudicator structure) allows outcomes that undermine the law's original anti-defection purpose, and that the remedy lies with Parliament rather than judicial reinterpretation alone.
Effect of Merger versus Simple Majority in a Legislature
A key concern raised in the plea is that the merger exception, if loosely applied, can allow numbers in a House to shift after an election without triggering disqualification, potentially converting an electoral minority into a working majority (or vice versa) through post-poll realignment rather than through the mandate given by voters.
Key Details
- The Tenth Schedule applies uniformly to the Lok Sabha, Rajya Sabha, and State Legislative Assemblies/Councils under Paragraph 1.
- Anti-defection provisions do not apply to a Speaker/Chairman who gives up party membership by convention on assuming office, nor (originally) to certain nominated or independent members joining a party within six months, per Paragraphs 5 and 2(2).
- A "split" is no longer a valid defence for individual disqualification (since the 2003 amendment); only a two-thirds legislature-party merger is recognised.
By seeking a stricter, twin-test reading of Paragraph 4 (genuine party merger plus two-thirds legislature-party consent), the petition asks the Court to close what it characterises as a loophole that lets the merger exception operate as a de facto revival of the repealed split defence.
- Tenth Schedule inserted by the 52nd Constitutional Amendment Act, 1985.
- Paragraph 4 merger exception threshold: not less than two-thirds of the members of the legislature party.
- Paragraph 3 (split exception, one-third threshold) deleted by the 91st Amendment Act, 2003.
- Kihoto Hollohan v. Zachillhu (1992): 5-judge bench, upheld Tenth Schedule, struck down Paragraph 7 (bar on judicial review) by 3:2 majority.
- Keisham Meghachandra Singh (2020): Speaker must decide disqualification pleas within three months barring exceptional circumstances.
