What Happened

The Tamil Nadu Legislative Assembly Speaker has been conducting disqualification proceedings against Members of the Legislative Assembly who voted against their party's whip during a confidence motion, invoking the Tenth Schedule of the Constitution (Anti-Defection Law).
Following the confidence motion for the Chief Minister's government on May 13, 2026, anti-defection proceedings were initiated against 25 AIADMK legislators who defied the party whip.
The Speaker subsequently dropped proceedings against 21 of the 25 MLAs after the party's general secretary issued separate letters pardoning the conduct of those members — a process that reflects the Tenth Schedule's internal party resolution mechanism.
Proceedings continue against the remaining 4 MLAs who have since resigned from the original party and joined a separate political formation, as their conduct constitutes voluntary relinquishment of party membership — a clear disqualification trigger under Paragraph 2(1)(a) of the Tenth Schedule.
A legal challenge was filed before the Madras High Court contending that accepting the resignations of 3 of these MLAs before the disqualification petitions were decided undermines the anti-defection provisions — raising a constitutional question about sequencing of Speaker's duty.

The Tenth Schedule: Origins and Constitutional Basis

The Tenth Schedule was inserted into the Constitution by the Constitution (52nd Amendment) Act, 1985, during the tenure of Prime Minister Rajiv Gandhi. It was enacted to curb political defections, which had destabilised governments in the post-1967 period of coalition politics (the era of "aaya ram, gaya ram"). The Schedule applies to members of both Parliament and state legislatures.

Enacted via 52nd Constitutional Amendment, 1985; inserted as the Tenth Schedule.
Applies to: Lok Sabha, Rajya Sabha, and all state legislative assemblies and councils.
Paragraph 2(1)(a): Disqualification if a member "voluntarily gives up the membership" of the political party that set them up for election.
Paragraph 2(1)(b): Disqualification if a member votes or abstains from voting in the House contrary to any direction issued by their political party (i.e., defies a whip), unless the member has obtained prior permission or the defiance has been condoned by the party within 15 days.
Paragraph 4 (Merger Exception): A split of at least two-thirds of the legislative party into a new party, or merger with another party by at least two-thirds of the members, does not attract disqualification. (The original split exception of one-third was removed by the 91st Constitutional Amendment, 2003, which also capped the size of the Council of Ministers at 15% of the House.)
The original Paragraph 7 barred judicial review; this was struck down in Kihoto Hollohan v. Zachillhu, 1992.

Connection to this news: The Tamil Nadu case is a textbook Paragraph 2(1)(b) situation — members voted against a party direction (the whip during the confidence motion). The Speaker's decision to continue proceedings only against the 4 who subsequently left the party reflects a correct reading of Paragraph 2(1)(a) for those who have voluntarily relinquished membership.

The Speaker's Quasi-Judicial Role Under the Tenth Schedule

Under the Tenth Schedule, the Speaker (or Chairman of the Upper House) is the sole adjudicatory authority for disqualification proceedings. Articles 102(2) and 191(2) of the Constitution vest this power exclusively in the Speaker/Chairman. The role is described as quasi-judicial because the Speaker must apply legal standards impartially, follow principles of natural justice, and give reasons for decisions — even though the Speaker is an elected political figure.

No court has jurisdiction to interfere with disqualification proceedings while they are pending before the Speaker; intervention is available only after the decision (post-Kihoto Hollohan).
The Speaker must act on a petition; the Tenth Schedule does not provide for suo motu action by the Speaker.
No time limit is prescribed in the Tenth Schedule itself for deciding disqualification petitions, which has led to prolonged pendency in several state assemblies.
The Supreme Court, in Keisham Meghachandra Singh v. Speaker, Manipur Legislative Assembly (2020), held that Speakers must decide disqualification petitions within a reasonable time — typically 3 months — and directed that courts can issue mandamus to the Speaker where there is unreasonable delay.
The Speaker's decision is subject to judicial review under Articles 32 and 226, but courts will not ordinarily interfere with the merits of the disqualification order; they review for procedural violations, mala fides, or constitutional infirmity.

Connection to this news: The Tamil Nadu Speaker proceeding with hearings against the 4 MLAs who left the party — while appropriately dropping proceedings against the 21 pardoned by the party — demonstrates the quasi-judicial standard: the proceedings must track the actual legal position (voluntary departure = disqualification) rather than political outcomes.

Kihoto Hollohan v. Zachillhu (1992): The Landmark Anti-Defection Ruling

The constitutional validity of the Tenth Schedule was challenged in this landmark five-judge Constitution Bench case. The Supreme Court delivered its judgment on February 18, 1992 (reported as 1992 Supp (2) SCC 651).

The Court upheld the constitutional validity of the Tenth Schedule in its entirety, including the Speaker's power to decide disqualification petitions.
Paragraph 7 struck down: Paragraph 7 of the original Tenth Schedule barred any court from questioning the disqualification proceedings. The Court held that this amounted to an amendment of Articles 136, 226, and 227 (judicial review provisions), and since such amendments require ratification by at least half the state legislatures under Article 368(2) proviso — which was not done — Paragraph 7 was unconstitutional and void.
The invalidation of Paragraph 7 opened Speaker's disqualification decisions to judicial review.
The Court clarified that the Speaker's decision is final subject to judicial review; it is not a "legislative" act but a "quasi-judicial" determination, meaning courts can examine it for jurisdictional errors and violations of natural justice.
The ruling also held that the Speaker retains authority even if a motion for their removal is pending in the House.

Connection to this news: The Madras High Court petition challenging the acceptance of MLA resignations before deciding disqualification petitions is squarely within the post-Kihoto Hollohan framework — courts can examine whether the Speaker's procedural choices violate the anti-defection framework.

The Merger Exception and the 91st Amendment

The 91st Constitutional Amendment Act, 2003 made two critical changes to the anti-defection framework: (1) it raised the threshold for a valid merger from one-third to two-thirds of the legislative party, and (2) it inserted Article 75(1A) and Article 164(1A), capping the size of the Union Council of Ministers and State Councils of Ministers at 15% of the total membership of the relevant House (minimum 12 ministers).

Before 2003: One-third of a legislative party could merge with another party without disqualification.
After 2003 (91st Amendment): Only a merger of at least two-thirds of the legislative party avoids disqualification.
The Tenth Schedule does not recognise an "independent split" as a defence — a member cannot claim immunity simply by forming a new faction.
Nominated members: If they vote in the House within 6 months of nomination without joining a party, they face no anti-defection liability; if they join a party after nomination, defection from that party triggers the Schedule.

Connection to this news: The 4 MLAs who left to join a new party (Tamilaga Vettri Kazhagam) do not benefit from the merger exception because they constitute far fewer than two-thirds of the AIADMK legislative party, making their disqualification proceedings legally straightforward.
