SC takes up Abhishek Banerjee’s plea seeking action against 20 rebel TMC MPs

The Supreme Court's decision to hear Abhishek Banerjee's plea regarding the disqualification of 20 Trinamool Congress (TMC) MPs who merged with the Nationalist Congress Party (NCP) brings into sharp focus the continuing constitutional debate surrounding India's anti-defection law, enshrined in the Tenth Schedule of the Constitution. This case is not merely a political dispute but a critical test of the institutional mechanisms designed to preserve party discipline and democratic accountability in Parliament. The background of this case lies in the 2024 political realignment where 20 TMC Lok Sabha MPs, led by senior leader Mukul Roy, joined the NCP, claiming a "merger" under Paragraph 4 of the Tenth Schedule. The TMC, however, contends that this move constitutes "voluntarily giving up membership" under Paragraph 2(1)(a), which attracts disqualification. The core legal question is whether a merger with another party — especially one not involving a split in the original party — can shield legislators from disqualification. The Supreme Court has previously held in Kihoto Hollohan v. Zachillhu (1992) that the Speaker's decision on disqualification is subject to judicial review, but the Court has also emphasized the need for Speakers to decide such petitions within a "reasonable time," a principle reiterated in Keisham Meghachandra Singh v. The Hon'ble Speaker, Manipur Legislative Assembly (2020), where a three-month outer limit was suggested. Key stakeholders include Abhishek Banerjee, TMC's national general secretary and nephew of Chief Minister Mamata Banerjee, who filed the plea; the 20 rebel MPs whose parliamentary membership hangs in balance; the Lok Sabha Speaker, who is constitutionally mandated to adjudicate disqualification petitions under Article 102 read with the Tenth Schedule; and the Election Commission of India, which recognizes party mergers for symbol allocation. The NCP, now split into two factions (Sharad Pawar and Ajit Pawar groups), adds another layer of complexity regarding which faction constitutes the "original party" for merger purposes. The significance of this case extends far beyond West Bengal politics. It tests the vitality of the anti-defection law, enacted through the 52nd Constitutional Amendment Act, 1985, and strengthened by the 91st Amendment Act, 2003, which deleted the "split" provision (originally Paragraph 3) that allowed one-third of a legislature party to defect without disqualification. The 91st Amendment retained only the "merger" exception (Paragraph 4), requiring two-thirds of the legislature party to agree to merge with another party. However, the law does not define "merger" clearly — whether it requires a formal resolution, EC recognition, or merely a claim by legislators. This ambiguity has been exploited repeatedly, as seen in Maharashtra (2022 Shiv Sena split), Goa (2022 Congress MLAs joining BJP), and Manipur (2020). Politically, the case underscores the tension between intra-party democracy and legislator autonomy. The Tenth Schedule was designed to curb "Aaya Ram Gaya Ram" politics, but critics argue it has stifled dissent within parties and concentrated power in party high commands. The Supreme Court's eventual ruling will clarify whether a merger must be substantive — involving organizational integration — or merely formal. It will also reinforce or dilute the Speaker's obligation to act promptly, a issue flagged by the Court in multiple judgments. Economically and governance-wise, frequent defections and delayed disqualification decisions undermine legislative stability, policy continuity, and public trust. In a coalition era, where governments often survive on thin margins, the anti-defection law's enforcement directly impacts governance quality. Looking ahead, the Supreme Court may lay down guidelines for: (1) defining "merger" under Paragraph 4 with procedural safeguards; (2) mandating a strict timeline for Speakers to decide disqualification petitions, possibly amending the Tenth Schedule to include a statutory deadline; and (3) clarifying the interplay between the Election Commission's recognition of party mergers and the Speaker's disqualification jurisdiction. This case could become a landmark precedent — akin to Kihoto Hollohan — shaping India's parliamentary democracy for decades. For aspirants, mastering this case means understanding not just the Tenth Schedule's text, but its judicial interpretation, political misuse, and reform imperatives.
