TMC MP Kakoli Ghosh claims support of 19 MPs to invoke Tenth Schedule's merger exception, mirroring AAP's Raghav Chadha's recent move, while facing legal and numerical hurdles in Lok Sabha.
Key points
Tenth Schedule of the Constitution mandates disqualification for defection unless two-thirds of a party's legislators merge with another party, as amended in 2003 to remove the one-third split provision.
Kakoli Ghosh asserts 19 TMC Lok Sabha MPs support NDA, aiming to replicate AAP's Raghav Chadha's Rajya Sabha merger strategy that was accepted by the Chair in April 2026.
[GS2-Polity] The crisis connects to parliamentary democracy principles under Article 191(2) as it tests whether electoral mandates can be transferred via legislative mergers against voters' original party choices.
Legal hurdles include the requirement for formal party merger (not just bloc formation), pending Supreme Court clarification on Goa defection case, and disputed numbers with TMC loyalists claiming only 13 MPs attended rebel meetings.
PDT Achary, former Lok Sabha Secretary General, clarifies Speaker cannot recognize a separate bloc under Tenth Schedule - only mergers between registered parties are protected.
[GS3-Governance] The episode reveals structural flaws in anti-defection law implementation, where technical compliance (two-thirds majority) may override democratic accountability of individual legislators to constituents.
Historical context includes Raghav Chadha's 2022 private member bill proposing stricter defection norms (three-fourths majority bar and 6-year contest ban), showing evolving legislative intent against floor-crossing.
Mahua Moitra argues constitutional morality demands by-elections for defectors since 2024 mandate was for TMC, not NDA, invoking the basic structure doctrine's representation principles.
West Bengal assembly precedent shows 58 of 80 TMC MLAs (72.5%) successfully merged with Ritabrata Banerjee's faction, demonstrating the clause's operationalization at state level.
Way Forward: Amend Tenth Schedule to require by-elections for merged legislators, establish time-bound Supreme Court benches for defection disputes, and introduce recall provisions for MPs changing party allegiance post-election.
Key terms
- Tenth Schedule
- Constitutional provision added by 52nd Amendment Act (1985) to curb defections, detailing disqualification rules for legislators switching parties or violating whip. Its Paragraph 4 allows exemption only if two-thirds of a party's legislators merge with another registered party, a critical UPSC topic for understanding parliamentary stability mechanisms.
- Anti-Defection Law
- Legal framework under Tenth Schedule aimed at preventing elected representatives from arbitrarily changing parties, preserving electoral mandates. UPSC relevance lies in its balance between party discipline (whip system) and legislative independence, with recent controversies testing its efficacy against mass defections.
- Merger Exception
- Clause in Tenth Schedule's Paragraph 4 permitting group defection if two-thirds of party legislators join another party without disqualification. Important for UPSC as it represents a legal loophole enabling engineered defections while preventing individual opportunism, as seen in Goa (2022) and Rajasthan (2020) crises.
- Whip System
- Parliamentary procedure where party leadership issues binding voting instructions to members, with violations attracting Tenth Schedule disqualification. Crucial for UPSC to understand party control mechanisms in Westminster systems and their tension with representative democracy principles under Articles 105-106.

Answer framework
Introduction
Briefly introduce the Tenth Schedule and its merger clause, mentioning its purpose to curb defections while allowing party mergers under specific conditions.
Legal Framework and Intent
Explain the Tenth Schedule's provisions, especially the two-thirds merger rule post-2003 amendment.
Original intent: Balance between preventing individual opportunism and allowing legitimate party realignments.
Democratic Challenges
Conflict with voter mandate (Article 191(2)) when elected representatives switch parties en masse.
Undermines accountability as legislators bypass by-elections despite changing allegiance.
Implementation Issues
Technical compliance (two-thirds majority) overriding democratic spirit, as seen in West Bengal assembly case.
Lack of clarity on 'merger' definition (Goa case) and Speaker's discretionary powers.
Judicial and Reform Perspectives
Supreme Court's role in interpreting merger clause (basic structure doctrine considerations).
Reform proposals: Raghav Chadha's private member bill, mandatory by-elections for merged legislators.
Conclusion
Suggest a balanced approach: Retain merger clause for political stability but introduce safeguards like by-election requirements and time-bound judicial oversight to enhance democratic accountability.
