Madras High Court Scrutinizes Unanimous Vote on Mekedatu Tribunal Resolution

Key takeaways
- Advocate General Vijay Narayan told the court that the Mekedatu resolution was amended and passed unanimously on June 19, 2026.
- Opposition whip Agri S.S. Krishnamurthy filed a petition claiming the amended portion of the resolution was never actually debated.
- Chief Minister C. Joseph Vijay accepted an amendment from Udhayanidhi Stalin to seek a special tribunal under federal law.
- The Madras High Court issued notices to the Assembly Secretary and the Union Ministry of Jal Shakti returnable by August 14, 2026.

The Dispute Over Legislative Procedure
During a Madras High Court hearing on July 30, 2026, Advocate General Vijay Narayan defended the legitimacy of an amended resolution passed by the Tamil Nadu Legislative Assembly. The resolution calls for the Union Ministry of Jal Shakti to establish a special tribunal under Section 4 of the Inter-State River Water Disputes Act, 1956, to address the Mekedatu Dam project. According to the Advocate General, the measure received unanimous support during the June 19, 2026 session.
Chief Minister C. Joseph Vijay initiated the proceedings by moving a resolution to block Karnataka's construction of the dam on the Cauvery River. Leader of the Opposition Udhayanidhi Stalin subsequently requested an amendment to include the demand for a new tribunal. Following a May 25 consultation with legal experts, the Chief Minister accepted this addition. Speaker J.C.D. Prabhakar then put the final amended text to a vote, which the Advocate General claims passed without objection from any member, including the petitioner.
Contested Claims and Judicial Intervention
The legal challenge, brought by AIADMK whip Agri S.S. Krishnamurthy, disputes the official narrative of the session. Senior counsel S.R. Rajagopal argued that while the original resolution was debated and approved, the last-minute amendment was never properly deliberated. The petitioner asserts that the House only sanctioned the documents circulated a day prior to the session, rather than the modified version presented on the floor.
The Division Bench, consisting of Chief Justice Sushrut Arvind Dharmadhikari and Justice G. Arul Murugan, has intervened to clarify the legislative record. The court issued formal notices to the Assembly Secretary, the Chief Secretary, and the Union Ministry of Jal Shakti. All parties must file their counter-affidavits within a two-week window.
Key Facts
- The resolution was officially passed in the Tamil Nadu Legislative Assembly on June 19, 2026.
- The amendment specifically requests a special tribunal under the Inter-State River Water Disputes Act of 1956.
- AIADMK whip Agri S.S. Krishnamurthy filed the writ petition challenging the validity of the amendment process.
- Chief Minister C. Joseph Vijay held a preliminary legal consultation on the matter on May 25, 2026.
What Happens Next
The case is scheduled to resume on August 14, 2026, which serves as the returnable date for the notices issued by the court. The respondents are expected to provide sworn statements addressing whether the amended resolution followed proper parliamentary procedure before the next hearing. The outcome will determine if the state's formal request for a federal tribunal remains legally sound.
