The Madras High Court on 13 October 2026 upheld the Tamil Nadu Assembly Speaker's acceptance of resignations tendered by six AIADMK legislators who had cross-voted in favour of the ruling TVK government during a confidence motion and subsequently joined the ruling party. The ruling provides significant relief to the TVK government, while simultaneously keeping alive the anti-defection disqualification proceedings against the six former legislators.

What the Court Ruled

A first bench comprising Chief Justice Sushrut Arvind Dharmadhikari and Justice G. Arul Murugan dismissed a petition filed by AIADMK whip Agri S. Krishnamurthy and others challenging the Speaker's decision. The bench held that the resignations were genuine and voluntary, and that the declaration of vacancies in the Assembly was constitutionally valid.

Crucially, the court clarified that the Speaker was not obligated to conduct an extensive inquiry into the alleged motives behind the resignations once their genuine and voluntary nature had been established.

Resignation vs Disqualification: Two Separate Tracks

The central legal question before the bench was whether pending disqualification proceedings under the Tenth Schedule of the Constitution — the anti-defection law — could bar the Speaker from acting on the resignations. The court categorically rejected this contention, holding that resignation and disqualification are separate and independent constitutional processes.

The Speaker was therefore competent to accept the resignations despite the unresolved disqualification petitions. However, the bench was equally emphatic that accepting the resignations did not render the pending disqualification cases academic or infructuous.

Speaker Directed to Decide Disqualification Cases

The court directed the Speaker to finally adjudicate the disqualification proceedings, with any finding carrying the consequences prescribed under the Constitution's Tenth Schedule. This means that even though the six legislators have relinquished their Assembly membership, a finding of disqualification would still carry constitutional significance — potentially affecting their eligibility for future office.

Notably, the bench also reaffirmed the High Court's authority under Article 226 of the Constitution to intervene if the Speaker failed to decide the disqualification petitions within a reasonable period, underscoring the judiciary's continuing supervisory role over legislative proceedings.

Background: Cross-Voting and the Confidence Motion

The case stems from a confidence vote in the Tamil Nadu Assembly, during which the six AIADMK legislators defied their party's whip and voted in favour of the TVK government. They subsequently resigned their Assembly seats and joined the ruling party — a sequence that the AIADMK challenged as violating the anti-defection law. This is not the first time Tamil Nadu politics has been roiled by floor-crossing disputes; the state has a long history of such constitutional battles dating back to the AIADMK-DMK rivalry of the 1980s and 1990s.

What Happens Next

With the petition dismissed, the six vacant Assembly seats will likely trigger by-elections, which could strengthen the TVK government's legislative numbers. The disqualification proceedings before the Speaker, however, remain pending and must be decided on their own merits. A disqualification finding, even post-resignation, could have downstream consequences on the legislators' political careers. The Speaker's timeline for concluding the disqualification cases is expected to come under scrutiny, given the court's explicit warning about the Article 226 oversight power.
