The Immediate Dispute

TMC Defectors: Disqualification Petitions Trigger Constitutional Test on Anti‑Defection Law

A delegation of Trinamool Congress (TMC) leaders led by national general secretary Abhishek Banerjee met Lok Sabha Speaker Om Birla on Friday and lodged petitions to disqualify twenty rebel MPs for defecting to the North East Congress (Tripura) (NCPI). The rebels, who approached the Speaker a week earlier claiming a merger with NCPI, face a demand to resign and seek fresh elections, while the Speaker’s ruling will hinge on constitutional provisions and Supreme Court precedents.

Abhishek Banerjee, flanked by MPs Kalyan Banerjee, Mahua Moitra, Saugata Roy and Derek O’Brien, presented twenty separate disqualification petitions to the Speaker. The rebels, led by Kakoli Ghosh Dastidar, argue that their merger with NCPI satisfies the statutory criteria for a separate parliamentary bloc. The TMC’s petition argues that the rebels have “sold their conscience” and must vacate their seats.

• ▸Twenty TMC MPs have been identified as rebels and are the subject of the petitions.
• ▸The meeting with Speaker Om Birla took place on Friday, 20 June 2024.
• ▸The rebels claim a merger with the NCPI, a party based in Tripura.
• ▸TMC demands that the rebels resign and trigger by‑elections under the Representation of the People Act 1951.
• ▸Abhishek Banerjee warned that any alleged “security cover” for the rebels must be examined by investigative agencies.

Legal Framework: Anti‑Defection Law

The anti‑defection regime is anchored in the Tenth Schedule of the Constitution, added by the 52nd Amendment in 1985. It defines “defection” as voluntarily giving up party membership or voting against party directives, and it provides a “merger” exception when at least two‑thirds of a party’s legislators agree to merge with another party. Crucially, the merger clause applies to the party as a whole, not merely to its legislative wing, a point the TMC emphasises.

• ▸The merger exception requires the consent of ≥ 2/3 of the total elected members of the party, not just the parliamentary group.
• ▸The anti‑defection law applies to both Lok Sabha and state assemblies, ensuring party discipline across levels.
• ▸Under Article 84 of the Constitution, a person is disqualified if they are not a member of the party on whose symbol they were elected.
• ▸Article 191 empowers Parliament to prescribe additional grounds for disqualification, which the anti‑defection law does.
• ▸The law was enacted to curb the “horse‑trading” that plagued several state governments in the early 1980s.

Speaker’s Role and Judicial Precedent

The Speaker, as the custodian of the House, exercises the quasi‑judicial authority to decide on disqualification petitions under Article 93 of the Constitution. This authority was affirmed by the Supreme Court in Kihoto Hollohan v. Zachillhu (1992), which held that the Speaker’s decision is final but subject to judicial review on limited grounds such as violation of natural justice or jurisdictional error. The Court also stressed that the Speaker must act “in accordance with the Constitution and the law,” a standard the TMC repeatedly invokes.

• ▸In Kihoto Hollohan v. Zachillhu, the Court upheld the Speaker’s jurisdiction while allowing limited judicial scrutiny.
• ▸The judgment clarified that the Speaker’s decision can be challenged only on procedural or jurisdictional grounds, not on policy merits.
• ▸The Speaker’s ruling
