Supreme Court Upholds TN Speaker's Decision on AIADMK MLA Disqualification

The Supreme Court on Friday, October 9, 2026, declined to intervene in the Tamil Nadu Assembly Speaker’s decision to close disqualification proceedings against a group of All India Anna Dravida Munnetra Kazhagam (AIADMK) legislators. These MLAs had supported the C. Joseph Vijay’s Tamilaga Vettri Kazhagam (TVK)-led government during a trust vote held in May. The apex court observed that the Speaker’s decision could not be challenged by an “interloper,” as reported by The Hindu.

A Bench comprising Chief Justice Surya Kant and Justices Joymalya Bagchi and V. Mohana dismissed a plea filed by advocate P.V. Selvakumar. The Bench emphasized the need to preserve the sanctity of the constitutional mandate under the Tenth Schedule, which contains the anti-defection law. "We are fully with you that sanctity of constitutional mandate must be preserved. But we must understand workings of a democratic system,” the Bench stated during the proceedings.

Mr. Selvakumar had initially approached the Supreme Court after the Madras High Court rejected his petition challenging the Speaker’s June 9 decision to drop the disqualification proceedings against the AIADMK legislators. The Speaker's action was based on a May 27 letter from the AIADMK's general secretary, which sought the withdrawal of the proceedings. The High Court had earlier ruled that Mr. Selvakumar, being a third party to the dispute, lacked the locus standi to interfere in the internal affairs of the AIADMK.

Advocate Nina Nariman, representing Mr. Selvakumar, argued that once the Speaker had entertained the disqualification petition, the proceedings ought to have been taken to their logical conclusion. She contended that the legislators had defied the party whip by supporting the government in the confidence vote. However, the Supreme Court Bench drew a distinction between defection and differences that may arise within a political party in a multi-party democracy.

The Bench articulated its stance, saying, “We have a multi-party system. One can say I prefer party C to be in power than party B. If the party had made an application, we could appreciate. But here, it appears you are at best an opportunistic interloper or at best a conscientious person adhering to minority philosophy.” The court further noted that the AIADMK itself had chosen not to pursue action against its legislators, questioning the need for a third party to intervene.

The Supreme Court also considered the potential burden and consequences, stating, “If one party could not muster the courage and missed by a very thin margin, if nobody supports, what will be the consequence? There will be fresh elections... Once a political party absolves defection due to political purpose, it will be difficult for us to bind them down in narrow legalistic terms.” While the legislators may have voted contrary to the party whip, the court found they had not ceased to be members of the AIADMK, leading to the dismissal of the plea.

The controversy originated after 25 AIADMK legislators defied their party whip and extended support to the TVK government during the May 13 confidence vote. The TVK, which had secured 108 seats in the Assembly elections, successfully won the trust vote with the backing of 144 legislators in the 234-member House, thanks to the support from these AIADMK members.

What to watch: The long-term implications of this ruling on party discipline and anti-defection law interpretations.
