Kihoto Hollohan v. Zachillhu: the Speaker as tribunal and the limits of anti-defection adjudication

The Fifty-second Constitutional Amendment Act 1985 inserted the Tenth Schedule into the Constitution to combat the defection-driven instability that had marked Indian legislative politics in the years following the 1967 general election. The Schedule provided for the disqualification of legislators on grounds of defection — voluntary giving up of membership of the political party on whose ticket they had been elected, voting or abstention contrary to the direction of the party whip without prior permission and without subsequent condonation, and certain related grounds. The decision on disqualification was vested in the Speaker of the House to which the member belonged, or the Chairman in the case of the Council of States. Paragraph 7 of the Schedule provided that, notwithstanding anything in the Constitution, no court should have any jurisdiction in respect of any matter connected with the disqualification of a member under the Schedule.

The constitutional validity of the Amendment and the Schedule was challenged in a clutch of petitions arising out of disqualification orders made by various Speakers between 1988 and 1991. The lead case, Kihoto Hollohan v. Zachillhu, came from Nagaland. On 18 February 1992 a five-judge Constitution Bench of L.M. Sharma J. (presiding), M.N. Venkatachaliah J., J.S. Verma J., K. Jayachandra Reddy J. and S.C. Agrawal J. decided the reference. The principal majority opinion was written by Venkatachaliah J. for himself, K. Jayachandra Reddy J. and Agrawal J. L.M. Sharma J. and Verma J. wrote separately, agreeing in part and dissenting in part. The judgment is reported at 1992 Supp (2) SCC 651, AIR 1993 SC 412, [1992] INSC 53.

The architecture of the Tenth Schedule

The Tenth Schedule, as it then stood, contained eight paragraphs. Paragraph 1 contained definitions, including "House", "legislature party" and "original political party". Paragraph 2 set out the grounds of disqualification — voluntary giving up of membership of the original political party, voting or abstention contrary to the whip without prior permission and without subsequent condonation, and (for independents) joining a political party after election. Paragraph 3 (since omitted by the 91st Amendment Act 2003) provided the split exception — a split recognised by one-third of legislators saved them from disqualification. Paragraph 4 provided the merger exception — a merger of the original political party accepted by at least two-thirds of the members of the legislature party. Paragraph 5 addressed the position of the Speaker, Deputy Speaker, Chairman and Deputy Chairman. Paragraph 6 vested the decision on disqualification in the Speaker or Chairman of the House. Paragraph 7 — the provision struck down — read: "Notwithstanding anything in this Constitution, no court shall have any jurisdiction in respect of any matter connected with the disqualification of a member of a House under this Schedule." Paragraph 8 empowered the Chairman or Speaker to make rules.

The Fifty-second Amendment had been passed by the requisite majorities in Parliament but had not been ratified by the legislatures of half the States — the procedure prescribed by the proviso to Article 368(2) for amendments seeking to make changes to certain enumerated provisions of the Constitution, including Articles 136, 226 and 227. The question whether such ratification was required for the Schedule as a whole, and whether the absence of ratification doomed the Amendment or only its offending parts, was central to the constitutional challenge.

The factual matrix the Bench worked with

The Bench considered the validity of the Tenth Schedule on two distinct planes — the procedural plane of Article 368(2) ratification and the substantive plane of fundamental and constitutional rights.

On the procedural plane, the question was whether Paragraph 7 of the Tenth Schedule, by ousting the jurisdiction of all courts including under Articles 136, 226 and 227, made a "change" in those Articles that required ratification under the proviso to Article 368(2). If it did, and ratification had not been obtained, the absence of ratification was — on the petitioner's argument — fatal to the entire Schedule, because the absence of ratification went to the constitutional validity of the Amendment as a whole.

On the substantive plane, the questions were whether the Tenth Schedule violated the freedom of speech and expression of legislators under Article 19(1)(a); whether it abridged the freedom of speech in Parliament protected by Articles 105 and 194; whether vesting the disqualification adjudication in the Speaker — an office held by an incumbent who would ordinarily be a member of one of the political parties — violated principles of natural justice and judicial impartiality; and whether the substantive grounds of disqualification in Paragraph 2, particularly the whip-based grounds, were consistent with the freedom of conscience and the representative character of the legislative office.

The reasoning

Paragraph 7 and the proviso to Article 368(2)

The five judges were unanimous that Paragraph 7 made a "change" within the meaning of the proviso to Article 368(2). The proviso lists Articles 136, 226 and 227 among those that cannot be changed without ratification by the legislatures of half the States. Paragraph 7, in terms, ousted the jurisdiction exercisable under those Articles in respect of disqualification matters under the Schedule. The exclusion of jurisdiction is the most direct kind of change to a jurisdictional Article. Ratification was therefore required. It had not been obtained. Paragraph 7 was bad.

The divergence opened on the consequences of the want of ratification.

The majority — Venkatachaliah J., K. Jayachandra Reddy J. and Agrawal J. — held that Paragraph 7 could be severed from the rest of the Schedule and that the want of ratification doomed only the unratified parts. The rest of the Schedule, which neither made nor required a change to any of the enumerated Articles, could stand. The doctrine of severability, as developed in R.M.D. Chamarbaugwalla v. Union of India, AIR 1957 SC 628, was held to apply, with appropriate adaptation, to constitutional amendments as to ordinary legislation.

The dissent — Sharma J. and Verma J. — would have held that the Tenth Schedule, having been passed as a single Amendment with Paragraph 7 as an integral feature, could not be saved by severance. The constitutional process under Article 368 is a process of presenting a particular text for the requisite parliamentary and (where required) State ratification. A text not ratified in its entirety is, on the dissenting view, not a text Parliament can pass into the Constitution merely because the unratified provisions might, viewed separately, have been within its ordinary amending power. The severability doctrine — drawn from the principle that legislators are presumed to wish what is constitutionally permissible to survive — operates differently in the constituent context: there is no presumption that the constituent body would have passed only the residue had it known the larger text would be cut down.

The majority therefore prevailed on the severability question; the rest of the Tenth Schedule was upheld; Paragraph 7 alone was struck down.

The Speaker as Tribunal

The consequence of striking down Paragraph 7 was that the Article 136, 226 and 227 jurisdictions over disqualification orders survived. The next question was the doctrinal character of the Speaker's role under Paragraph 6. The Bench unanimously held that the Speaker, when adjudicating disqualification under the Tenth Schedule, acts as a Tribunal — an authority deciding a justiciable controversy by application of identified norms — and not in his ordinary capacity as the presiding officer of the House.

The characterisation has structural consequences. As a Tribunal, the Speaker's decisions fall within Article 136 of the Constitution (the Supreme Court's discretionary appellate jurisdiction over tribunals) and within Articles 226 and 227 (the High Court's writ jurisdiction and the High Court's superintending jurisdiction over tribunals). The fact that the Speaker is also a constitutional functionary with a presiding role in the House does not insulate the Tribunal function from the jurisdictional structure that Articles 136, 226 and 227 establish.

The Speaker-as-Tribunal characterisation also imports an obligation of impartiality and adherence to natural justice. The Bench rejected the argument that the assignment of the disqualification adjudication to a partisan officer was itself unconstitutional — the Speaker, on the Bench's view, was bound by office to act impartially when discharging the Tribunal function, and the constitutional design rested on that expectation. The argument that the system was structurally flawed because Speakers had not, in practice, lived up to that expectation was held to be an argument against particular Speakers in particular cases, not against the constitutional design.

Scope of judicial review

The Bench then laid down the scope of judicial review under Articles 136, 226 and 227 over the Speaker's decisions. The review is limited. It is available on the following grounds:

1. Jurisdictional error — the Speaker has acted without authority under the Schedule.
2. Mala fides — the Speaker has acted from improper motives.
3. Perversity — the Speaker's decision is so unreasonable that no reasonable Tribunal could have made it.
4. Violation of constitutional mandates — the Speaker's decision contravenes a constitutional norm.
5. Breach of natural justice — the Speaker has failed to give the affected member a fair hearing.

The grounds are familiar in the Wednesbury and Article 226 writ-jurisdiction lexicon. They exclude review on the merits — the Court will not substitute its own view of the facts or the application of the Schedule for the Speaker's. The review is supervisory, not appellate.

The Bench added a critical timing limitation. Ordinarily, judicial review of the Speaker's actions under the Schedule is available only after the Speaker has made a final order. Interim or interlocutory orders of the Speaker in the course of the disqualification proceedings are not, ordinarily, susceptible to interim judicial interference. The rationale is the same as that which animates the Article 329(b) bar in Mohinder Singh Gill v. Chief Election Commissioner, (1978) 1 SCC 405 — the constitutional process must be allowed to run its course, and judicial review must wait for a decision that is ripe for review.

Article 19(1)(a) and the freedom of conscience

The Bench rejected the argument that Paragraph 2(1)(b) — disqualification for voting or abstention contrary to the whip — violated the freedom of speech and expression of legislators under Article 19(1)(a) or the related freedom of conscience.

The reasoning had two strands. The first was structural. Articles 105 and 194 govern the freedom of speech in Parliament and in State Legislatures; the freedom of speech relevant to the legislator's vote is the constitutional freedom under those Articles, not the Article 19(1)(a) freedom available to citizens at large. The second was substantive. The Tenth Schedule does not prohibit a legislator from voting in any particular way; it provides that a legislator who votes contrary to the whip without prior permission and without subsequent condonation may, by operation of the Schedule, be disqualified. The legislator retains the choice; the consequence of the choice is one the legislator must reckon with. That is not a restriction on freedom but a structuring of accountability.

The freedom-of-conscience argument was disposed of in similar terms. The Schedule respects the legislator's choice on matters of conscience by providing for the possibility of permission and condonation; the disqualification operates only where party discipline is rejected without those safeguards. The structural premise — that a legislator elected on a party platform owes the electorate a duty to honour that platform — is one the Constitution-makers were entitled to embed in the Schedule.

The doctrinal contribution

The judgment operates on at least four planes.

First, on the constitutional-amendment plane, the judgment installs the doctrine of severability for amendments under Article 368. The proposition that an Amendment can be partially struck down — with the offending provisions falling and the residue surviving — is now first principle. It has been deployed repeatedly since: in the post-Kesavananda line on the 25th Amendment, in Minerva Mills v. Union of India, (1980) 3 SCC 625, in I.R. Coelho v. State of Tamil Nadu, (2007) 2 SCC 1. The dissent in Kihoto Hollohan — that severability cannot save a constitutional amendment that was passed as a single text — remains the minority position but is regularly invoked in academic and forensic argument.

Second, on the anti-defection plane, the judgment installs the framework within which all subsequent Tenth Schedule litigation operates. The Speaker is a Tribunal; the Speaker's decisions are reviewable on identified limited grounds; the review ordinarily attends the final order. That framework has structured Ravi S. Naik v. Union of India, 1994 Supp (2) SCC 641, G. Viswanathan v. Speaker, Tamil Nadu Legislative Assembly, (1996) 2 SCC 353, Mayawati v. Markandeya Chand, (1998) 7 SCC 517, Jagjit Singh v. State of Haryana, (2006) 11 SCC 1, Rajendra Singh Rana v. Swami Prasad Maurya, (2007) 4 SCC 270, Nabam Rebia and Bamang Felix v. Deputy Speaker, Arunachal Pradesh Legislative Assembly, (2016) 8 SCC 1, Keisham Meghachandra Singh v. Speaker, Manipur Legislative Assembly, (2020) 5 SCC 689, and Subhash Desai v. Principal Secretary, Government of Maharashtra, (2023) 6 SCC 481.

Third, on the judicial-review plane, the judgment installs a particular model of supervisory review over constitutional functionaries acting in quasi-judicial roles. The five grounds — jurisdictional error, mala fides, perversity, violation of constitutional mandates, breach of natural justice — track the standard administrative-law grounds but apply them to a constitutional Tribunal sui generis. The model has informed judicial review of Governors' discretionary functions under Article 163, of the President's Article 72 clemency decisions, and of other constitutional functionaries acting in quasi-judicial roles.

Fourth, on the separation-of-powers plane, the judgment articulates a constrained, post-final-order model of judicial intervention in the legislative house's internal disciplinary processes. The constitutional process — Speaker's adjudication, Articles 136/226/227 review — must be allowed to run; the courts do not pre-empt that process by interim mandamus or prohibition.

What the judgment did not decide

Three issues Kihoto Hollohan did not address and that subsequent cases have had to work out.

First, the Bench did not address the question of what is to happen when the Speaker simply does not decide a disqualification petition within a reasonable time. The Speaker-as-Tribunal characterisation establishes a duty to decide; the post-final-order review framework leaves a gap when no final order is made at all. Keisham Meghachandra Singh v. Speaker, Manipur Legislative Assembly, (2020) 5 SCC 689, addressed the gap by suggesting a three-month indicative time-frame and by holding that the High Court can, in appropriate cases, issue directions to the Speaker to decide within a stipulated time.

Second, the Bench did not address whether the Speaker, acting under the Tenth Schedule, is subject to pre-decisional review where the Speaker is himself facing a notice of no-confidence — does the pendency of the no-confidence notice disable the Speaker from acting under the Schedule? Nabam Rebia and Bamang Felix v. Deputy Speaker, Arunachal Pradesh Legislative Assembly, (2016) 8 SCC 1, answered yes — but that answer has now been doubted in Subhash Desai v. Principal Secretary, Government of Maharashtra, (2023) 6 SCC 481, which has referred the question to a seven-judge Bench.

Third, the Bench did not address the post-2003 architecture introduced by the Constitution (Ninety-first Amendment) Act 2003, which omitted Paragraph 3 (the split exception) and tightened the merger condition in Paragraph 4. The 2003 amendments changed the substantive grounds; the Kihoto Hollohan framework continues to govern the adjudicatory architecture.

The doctrinal arc

Behind the case is Kesavananda Bharati v. State of Kerala, (1973) 4 SCC 225, and Indira Nehru Gandhi v. Raj Narain, 1975 Supp SCC 1, in which the basic-structure doctrine had first cut down a fresh amendment; and the long line on the proviso to Article 368(2), including Sajjan Singh v. State of Rajasthan, AIR 1965 SC 845, and Golaknath.

Ahead lies the post-1992 Tenth Schedule jurisprudence. Ravi S. Naik held that "voluntarily giving up membership" need not require formal resignation; G. Viswanathan applied the disqualification to members who continued in the party after the original party had split or merged. Jagjit Singh, Rajendra Singh Rana and Balchandra L. Jarkiholi v. B.S. Yeddyurappa, (2011) 7 SCC 1, addressed the standard of review and the duties of the Speaker. Nabam Rebia addressed the no-confidence-notice question; Keisham Meghachandra Singh the timing question; Subhash Desai the structural questions of who appoints the whip and recognises the leader of the legislature party, and referred the Nabam Rebia question to a seven-judge Bench.

The doctrine has also informed judicial review of constitutional functionaries — S.R. Bommai v. Union of India, (1994) 3 SCC 1, on the proclamation under Article 356; Manoj Narula v. Union of India, (2014) 9 SCC 1, on the Prime Minister's Article 75(1) discretion; and Anoop Baranwal v. Union of India, (2023) 6 SCC 161, on the appointment of the Election Commissioners.

What practitioners take from the case

For the constitutional and election-law bar in 2026, Kihoto Hollohan remains live in four operational respects.

Constitutional amendments are severable in appropriate cases. Where an Amendment contains provisions that attract the proviso to Article 368(2) and have not been ratified, those provisions can fall while the residue stands.

The Speaker, when acting under the Tenth Schedule, is a Tribunal. The implications are jurisdictional (Articles 136, 226, 227 attract) and procedural (the natural-justice obligation is engaged).

Judicial review is supervisory, not appellate, and ordinarily post-final-order. The five-ground framework — jurisdictional error, mala fides, perversity, violation of constitutional mandates, breach of natural justice — defines the analytic terrain. Pre-decisional intervention requires exceptional justification; the Nabam Rebia question is under reference to a seven-judge Bench in Subhash Desai.

The whip-based grounds are constitutionally valid notwithstanding their effect on freedom of conscience. The exceptions are those textually written into the Schedule — prior permission, subsequent condonation, the Paragraph 4 merger exception as it now stands.
