An AIADMK Whip asked the Madras High Court to strike down part of a Tamil Nadu Assembly resolution on the Mekedatu Dam, saying the demand for a fresh water tribunal had been slipped in without a separate vote. The Court refused to look into it: Article 212 of the Constitution bars courts from questioning what happens inside a legislature on the ground of a procedural irregularity, and none of the narrow exceptions applied.
Chennai: The Madras High Court has dismissed a writ petition challenging a resolution of the Tamil Nadu Legislative Assembly on the Mekedatu Dam issue, holding that the grievance, that a portion of the resolution was incorporated without being separately moved, seconded, debated or voted upon, is barred by Article 212 of the Constitution, which insulates the internal proceedings of a legislature from judicial scrutiny on the ground of procedural irregularity [Agri S.S. Krishnamurthy v. The Secretary, Tamil Nadu Legislative Assembly and Others].
A Division Bench of Chief Justice Sushrut Arvind Dharmadhikari and Justice G. Arul Murugan dismissed the petition, filed by AIADMK Official Whip Agri S.S. Krishnamurthy.
The challenge
The petitioner’s case was that the Government Resolution circulated to Members on June 18, 2026 objected to the Karnataka Government’s proposal to build a dam at Mekedatu and asked the Union Government to withhold clearances, but did not contain any demand for a fresh tribunal under Section 4 of the Inter-State River Water Disputes Act, 1956. That demand, he contended, surfaced only during the debate on June 19, when the Leader of the Opposition raised it and the Chief Minister accepted it, and was incorporated into Resolution No. 2/2026 without being separately moved, seconded, debated or put to a distinct vote. He sought to quash that portion, and to have the original circulated text treated as the validly adopted resolution.
The Advocate General, for the Assembly Secretary and the State, contended that the writ petition was barred by Article 212 of the Constitution and ought to be dismissed in limine.
The Article 212 bar
The Court held that Article 212(1), which provides that the validity of any proceedings in a State Legislature shall not be called in question on the ground of any alleged irregularity of procedure, squarely covered the grievance. The complaint that the resolution was adopted without a separate motion or vote was, the Court held, quintessentially a complaint of procedural irregularity, precisely the category that Article 212(1) places beyond the reach of the courts. The provision, it observed, protects the House’s control over the conduct of its own business, and reflects a constitutional scheme of mutual deference between the High Court and the State Legislature regarding their internal functioning; the High Court is not an appellate body over the Legislature, nor the Legislature an inferior organ to the High Court.
That bar, the Court noted, is subject only to narrow exceptions, cases of such gravity that they transcend the scheme of mutual deference, such as want of jurisdiction, substantive illegality, mala fides, or the breach of a constitutional limitation. None of those, it held, was made out; a grievance about the manner in which a resolution was moved and adopted did not rise to that level, and the writ petition was, on that ground alone, not maintainable.
In any event, no case on merits
Although it held the petition barred at the threshold, the Court went on to hold that it would fail on the merits as well. It noted that the Speaker, after narrating the sequence step by step, had ruled that no illegality had occurred in the procedure followed on June 19, and that this ruling was not questioned within the House at the time; the petitioner had offered no reason why the Court should reach a different conclusion on the identical facts.
More fundamentally, the Court held, Members who were present and had the opportunity to object, but chose to vote “Aye” or to remain silent, could not weeks later ask a court to treat their own silence as a nullity. The principle that a person who stands by and permits an act without protest cannot later complain of it, the Court observed, applies to the floor of a legislature as much as to any other public proceeding; this was not a case of a citizen shut out or misled, but of a Member, and the party he belongs to, who was present when the amendment was proposed, read out and voted upon, and whose party’s subsequent attempt to reopen the issue within the House had itself been unsuccessful. Finding no prejudice “ex facie apparent”, the Court held the challenge failed both on the Article 212 bar and on its merits, and dismissed the petition.
Why it matters
The judgment is a clear statement of the limits of judicial review over what happens inside a legislature. Article 212, like its counterpart Article 122 for Parliament, embodies a deliberate constitutional choice to leave the conduct of legislative business, how a motion is moved, debated and voted, to the House and its presiding officer, and to bar courts from invalidating proceedings for procedural irregularities. The rationale is the separation of powers: each organ is master of its own internal functioning, and a court that policed the procedural minutiae of a debate would trench upon the autonomy the Constitution guarantees the legislature.
The distinction that does the work is between procedural irregularity and substantive illegality. A mere departure from the rules of procedure, or a failure to separately move or vote on an amendment, is immunised by Article 212; only a defect that goes beyond procedure, a want of jurisdiction, a violation of a constitutional mandate, or mala fides, can lift the bar. The petitioner’s grievance fell on the wrong side of that line, and the Court’s reasoning underscores that the exceptions are narrow and reserved for cases of real constitutional gravity, not for disputes about how a resolution was adopted.
The Court’s alternative holding on the merits adds a practical dimension familiar from public law: a party present on the floor, who could have objected at the time and did not, cannot later invite a court to undo the outcome. The judgment thus turns on the legal architecture of legislative privilege and judicial restraint, rather than on the underlying political controversy over the Mekedatu project or the Cauvery dispute, on which the Court expressed no view; those inter-State questions lie in other forums, while the conduct of the Assembly’s own proceedings remains, by constitutional design, its own preserve.
