Anti-Defection Law: The Merger Exception Under the Tenth Schedule
Six of nine Lok Sabha MPs from a Shiv Sena faction skipped an emergency parliamentary party meeting, signalling a likely merger with another legislative group.
The rebel MPs submitted a letter to the Lok Sabha Speaker invoking the merger route under Paragraph 4 of the Tenth Schedule to avoid disqualification.
The parent party indicated it would initiate disqualification proceedings, raising a constitutional question: does a merger of the legislature party — without action by the original political party — satisfy the conditions under the Tenth Schedule?
The Tenth Schedule and Anti-Defection Law
The Tenth Schedule was inserted into the Constitution by the 52nd Constitutional Amendment Act, 1985. It lays down grounds for disqualification of members of Parliament and State Legislatures on the basis of defection from their political party.
Rebel MPs invoked Paragraph 4 (merger exception) to pre-empt disqualification proceedings by their parent party.
The Merger Exception: Paragraph 4
Paragraph 4 of the Tenth Schedule provides a protected category: members who merge with another political party are not disqualified if at least two-thirds of the members of the legislature party agree to the merger.
Six MPs (exactly 2/3 of nine) joining together meets the numerical threshold under Paragraph 4.
The Political Party vs. Legislative Party Distinction
The Supreme Court in Subhash Desai v. Principal Secretary, Governor of Maharashtra (2023) drew a clear constitutional line: the original political party and its legislative wing are distinct entities. A merger cannot be manufactured by legislators alone.
Key Details
- The "original political party" is the party as it exists under its constitution — not just its elected wing.
- Paragraph 4 requires the original political party to have merged with another party; a unilateral declaration by MPs that they are merging does not satisfy this.
- If the national executive of the original party has not merged, rebels claiming Paragraph 4 protection may still face disqualification proceedings.
- The Speaker decides the disqualification petition, subject to judicial review by the Supreme Court or High Courts.
The constitutional viability of the rebel MPs' merger claim turns on whether their parent party's organizational body — not just the legislative faction — has sanctioned the merger. This is the precise question the 2023 Supreme Court ruling addressed in the context of the earlier Maharashtra political crisis.
Speaker's Role Under the Tenth Schedule
Key Details
- The Speaker acts in a quasi-judicial capacity when deciding disqualification petitions under the Tenth Schedule.
- The Speaker must grant a reasonable opportunity of being heard before deciding.
- The Supreme Court has held (post-Kihoto) that courts can examine the Speaker's decision for patent illegality, but cannot intervene during pendency of the petition.
- The Election Commission determines symbol allocation when rival factions each claim to be the "real" party — a separate process from Tenth Schedule adjudication.
Any disqualification petition filed by the parent party's whip will be adjudicated by the Lok Sabha Speaker. Simultaneously, the two factions may approach the Election Commission over the party name and symbol — a distinct proceeding.
- Constitutional provision: Tenth Schedule — inserted by 52nd Constitutional Amendment Act, 1985
- Merger threshold: 2/3 of members of the legislature party (Paragraph 4)
- Disqualification authority: Lok Sabha Speaker (for Lok Sabha members)
- Key precedent: Kihoto Hollohan v. Zachillhu (1992) — Tenth Schedule upheld; Speaker's order subject to judicial review
- 2023 precedent: Subhash Desai v. Principal Secretary, Governor of Maharashtra — original political party and legislative party are distinct; merger must originate in the party, not just the legislature wing
- Effect of disqualification: Loss of seat; does not bar future candidacy
- IPC analogy (Election Commission): Symbols Order 1968 governs rival faction disputes over name/symbol; ECI has exclusive jurisdiction
- No split protection since 1985 amendment: The 91st Constitutional Amendment Act (2003) removed the earlier one-third split provision; only merger (2/3) now protects from disqualification
