Power Struggle in the Bengal Assembly: High Court Upholds Speaker’s Authority on LoP Appointment

In a significant legal development regarding the internal governance of the West Bengal Legislative Assembly, the Calcutta High Court has refused to grant an interim injunction to senior Trinamool Congress ( AITC ) leader Sobhandeb Chattopadhyay. The petitioner had sought to challenge the recognition of a rival faction's choice, Ritabrata Banerjee, as the Leader of the Opposition .

The dispute stems from a fractures within the AITC following the 2026 Assembly elections, where the party secured 80 seats. The court’s decision underscores the finality of the Speaker’s role in determining the Leader of the Opposition based on the " greatest numerical strength " within the House, as governed by the Bengal Legislative Assembly (Members’ Emoluments) Act, 1937 .

A Deepening Divide: The Timeline of Contention

The internal rift became public when the party high command’s nomination of Sobhandeb Chattopadhyay was challenged by a rebel faction led by Ritabrata Banerjee. The conflict escalated when the Speaker’s office discovered discrepancies in the signatures provided by the petitioner in support of his appointment. An FIR was subsequently filed by the authorities alleging the fabrication and manufacture of supporting documents.

By June 2026 , 58 out of the 80 AITC MLAs had submitted a joint representation to the Speaker, asserting that they constituted the majority and expressing their support for the rebel-nominated Leader of Opposition.

Arguments from the Bench and Bar

Representing the petitioner, counsel argued that the Tenth Schedule of the Constitution mandates that a party-recognized leader must be prioritized, citing Subhash Desai v. Principal Secretary, Governor of Maharashtra . The petitioner contended that the Speaker improperly entertained individual representations from MLAs, disregarding the party’s official communication.

Conversely, the respondents, including the State’s counsel, argued that the Speaker acted in accordance with Explanation II of Section 3 of the 1937 Act , which makes the Speaker’s certification of the Leader of the Opposition final and conclusive. They emphasized that the court’s power under Article 226 is supervisory and does not extend to performing the Speaker's function of verifying legislative numbers.

Legal Analysis: The Limits of Judicial Review

Justice Krishna Rao, in his order, noted that the court’s role under Article 226 is not akin to appellate jurisdiction . The court observed that it must allow for the investigative process—currently involving a police inquiry into the alleged forged signatures—to proceed without premature interference. By refusing to stay the appointment, the court maintained the status quo, effectively ruling that the Speaker’s determination, based on the personal verification of 56 MLAs, satisfies the current requirement of demonstrating " greatest numerical strength ."

Key Observations

  • On the Speaker's Discretion: "If any doubt arises as to which is or was at the material time the party in opposition... having the greatest numerical strength ... the question shall be decided... by the Speaker of the said Assembly, and his decision, certified in writing under his hand, shall be final and conclusive."
  • On the Petitioner’s Case: "This Court did not find any prima facie case and balance of convenience and inconvenience in favour of the petitioner for grant of interim order as prayed for by the petitioner."
  • On Judicial Limitation: "The Power of the High Court under Article 226 of the Constitution of India is not akin to appellate power. It is a supervisory power ... ensuring that the decision is arrived at in accordance with the procedure prescribed by law."

The Road Ahead

The Court has directed the respondents to file an affidavit-in-opposition within three weeks. With the interim relief denied, the appointment of the respondent-nominated LoP remains in effect until the matter is revisited on July 28, 2026 . This case serves as a critical precedent for how courts differentiate between internal party disputes and the statutory authority vested in the Speaker to ensure the functional continuity of the Legislative Assembly.
