3. Background & Evolution

Year Milestone
1967–77 Rampant floor-crossing post-1967 elections precipitated the need for anti-defection legislation
1985 52nd Constitutional Amendment Act inserted the Tenth Schedule into the Constitution [S1]
1992 Kihoto Hollohan v. Zachillhu — Supreme Court upheld validity of Tenth Schedule; ruled Speaker's decision is subject to judicial review on grounds of natural justice/mala fides, but only after the decision is made [S1]
2003 91st Constitutional Amendment abolished the one-third split exception (para 3 of Tenth Schedule); merger of ≥ two-thirds of party strength is now the only valid merger defence [S1]
2023 Subhash Desai v. Principal Secretary (Maharashtra Shiv Sena case) — Supreme Court held that the Speaker cannot adjudicate disqualification petitions while their own election as Speaker is sub-judice; recommended independent tribunal [S1]

Predecessors: The Anti-Defection Law replaced the informal "conscience vote" norm; earlier, the only check was the moral suasion of party discipline.


4. Core Static Facts

Definitions - Defection (voluntary): A member voluntarily gives up membership of the political party they represent. [S1] - Defection (whip violation): A member votes contrary to or abstains from voting as directed by the party whip. [S1] - Condonation: The party (through authorised leader) can condone the act of defection within 15 days of the vote, nullifying any disqualification action. [S2] - Merger exception: Disqualification does not apply if at least two-thirds of the legislative party merges with another party. [S1]

Implementing Authority - Presiding Officer (Speaker/Chairman of the House) is the sole adjudicating authority on disqualification petitions. [S1] - For Parliament: Lok Sabha Speaker / Rajya Sabha Chairman. - For State Assemblies: State Assembly Speaker / Legislative Council Chairman.

Enabling Provision - Tenth Schedule, Constitution of India (inserted by 52nd Constitutional Amendment Act, 1985). [S1] - Para 2: Grounds for disqualification. - Para 4: Exception for merger (≥ two-thirds). - Para 6: Speaker/Chairman as final authority (subject to judicial review post-decision). - Para 7: Bars courts from intervening before the Presiding Officer decides.

Key Numbers - Original Tenth Schedule had Para 3 (one-third split exception) — abolished in 2003 by 91st Amendment. [S1] - Condonation window: 15 days from date of the vote. [S2] - Tamil Nadu case: 25 MLAs violated whip; 4 resigned; 21 remained subject to proceedings. [S2]

10. Common Errors / Trap Areas

  1. Wrong year for Tenth Schedule: Many confuse the 52nd Amendment (1985) with the 91st Amendment (2003). The Tenth Schedule originated with the 52nd; the 91st only amended it by removing the split exception.
  2. Confusing the merger threshold: The valid merger threshold under Para 4 is two-thirds of the legislative party — not the organisational party, not a simple majority.
  3. Speaker vs. Election Commission: The Speaker is the adjudicating authority under the existing law; the Election Commission role is only a reform recommendationnot current law. Do not conflate.
  4. Scope of Para 7 court bar: Courts are barred during pendency of proceedings, not permanently. Post-decision review is available under Articles 136, 226, 227. Aspirants often think courts have no jurisdiction.
  5. Condonation window confusion: The 15-day condonation period runs from the date of voting (not date of petition, not date of Speaker's notice). The Tamil Nadu case is the clearest illustration of this deadline's significance.
