Nabam Rebia v. Deputy Speaker, Arunachal Pradesh Legislative Assembly, Civil Appeal Nos. 6203-6204 of 2016, a 5-judge Larger Bench of the Supreme Court of India (Gauhati HC reversed), is the governing authority on Governor-Legislature relations and Speaker impartiality under the Tenth Schedule of the Constitution. The ratio — narrow Article 163(2) discretion, limited Article 212 immunity, Speaker facing removal cannot adjudicate Tenth Schedule petitions — transfers directly to every State political-crisis litigation. Counsel advising on floor-test strategy, disqualification challenges and Article 226/32 writs should plead Nabam Rebia alongside Shamsher Singh v. State of Punjab (1974) and Kihoto Hollohan v. Zachillhu (1992). A 7-Judge reference is pending on the Speaker-removal aspect.
Key Takeaways for Counsel
- Plead narrow Article 163(2) discretion to resist politically motivated gubernatorial action.
- Use Article 212's non-absolute reach to open judicial review for constitutional violations.
- Challenge Tenth Schedule orders where the Speaker faced a pending removal motion.

How did the case reach the Supreme Court?
Answer: Nabam Rebia reached the Supreme Court by Civil Appeal under Article 136 of the Constitution against the Gauhati High Court's order. The HC had held that the Governor's actions advancing the Arunachal Pradesh Assembly session and the rebel-MLA proceedings removing the Chief Minister were non-justiciable under Articles 163 and 212. The 5-judge Bench reversed this, laying down binding principles on Governor-Legislature relations.
| Stage | Forum | Outcome | Governing provision |
|---|---|---|---|
| Political crisis | Arunachal Pradesh (Nov 2015 – Mar 2016) | 21 MLAs rebel; Speaker removed; CM voted out | Constitutional convention |
| HC | Gauhati High Court | Governor's actions and proceedings held non-justiciable | Articles 163, 212 Constitution |
| Final | Supreme Court of India (5-Judge Larger Bench) | Gauhati HC judgment reversed | Article 136 Constitution |
What are the facts in brief?
Answer: In late 2015, 21 Congress MLAs rebelled against Arunachal Pradesh Chief Minister Nabam Tuki and Speaker Nabam Rebia. The Governor advanced the Assembly session from January 2016 to 16 December 2015 without cabinet advice. A lock-out of the Assembly prevented entry; the rebel MLAs convened in a community hall, purported to remove Speaker Rebia and voted out the Chief Minister. Speaker Rebia retaliated by disqualifying 14 rebel MLAs under the Tenth Schedule; the Deputy Speaker quashed that order the same day.
The statutory and doctrinal context is the triad of Articles 163 (Council of Ministers / Governor's discretion), 212 (non-justiciability of legislative proceedings) and the Tenth Schedule (anti-defection / disqualification). The 5-judge Bench consolidated decades of authority — Shamsher Singh (1974), Kihoto Hollohan (1992), S.R. Bommai (1994), Rameshwar Prasad (2006) — and reversed the Gauhati High Court's broad non-justiciability ruling.
What issues did the court frame?
Answer: The 5-judge Bench framed three issues in Nabam Rebia, centred on the constitutional balance among Governor, Speaker and Legislature.
- Issue 1: What is the scope of the Governor's discretionary power under Article 163(2)?
- Issue 2: Does Article 212 bar judicial review of legislative proceedings in all circumstances?
- Issue 3: Can a Speaker adjudicate Tenth Schedule disqualification petitions while a motion for his removal is pending before the House?
What did the court hold?
Answer: In Nabam Rebia v. Deputy Speaker, Civil Appeal Nos. 6203-6204 of 2016, the 5-judge Larger Bench held, reversing the Gauhati High Court, that Governor's discretion is narrow and a Speaker facing removal cannot sit on Tenth Schedule matters. Each holding below is pleadable as a standalone proposition.
- Holding 1: The Governor's Article 163(2) discretion is confined to situations the Constitution expressly carves out — political-session advancement is not one of them.
- Holding 2: Article 212 does not immunise legislative actions from judicial review where constitutional violations, mala fide intent or procedural unfairness are shown.
- Holding 3: A Speaker cannot adjudicate Tenth Schedule disqualification petitions while a motion for his own removal is pending — it offends nemo iudex in causa sua.
- Holding 4: The Council of Ministers' aid and advice under Article 163(1) is the default rule; Article 163(2) discretion is a narrow exception.
- Holding 5: The Gauhati High Court's broad non-justiciability holding misconstrued Articles 163 and 212 and was set aside.
Why does Nabam Rebia matter today?
Answer: Nabam Rebia v. Deputy Speaker matters today because it operates as the governing authority in every State political crisis — from Maharashtra's 2022 Shiv Sena split to recent Tenth Schedule challenges in Karnataka, Madhya Pradesh and Manipur. The ratio feeds directly into floor-test litigation, Governor's invitation-to-form-government writs and disqualification challenges. Counsel drafting pleadings in any such matter must front-load Nabam Rebia and its underlying authority in Shamsher Singh and Kihoto Hollohan.
Current Statutory Framework (as of 2026-04)
Answer: The constitutional framework interpreted in Nabam Rebia — Articles 163, 174, 212 and the Tenth Schedule — is unchanged. The 2025 reference to a 7-Judge Constitution Bench is pending and does not disturb the binding force of the 5-judge ruling.
Article 163 Constitution → Article 163 Constitution (unchanged)
Article 163(1) continues to operate as the default aid-and-advice rule; Article 163(2) remains the narrow exception. Nabam Rebia confirms that express constitutional carve-outs — not political convenience — define the contours of discretion.
Article 212 Constitution → Article 212 Constitution (unchanged)
Article 212 continues to bar judicial review of legislative proceedings on grounds of procedural irregularity. Nabam Rebia carves out a narrow but significant exception: review is available for constitutional violations, mala fides and procedural unfairness amounting to constitutional breach.
Tenth Schedule → Tenth Schedule (unchanged)
The Tenth Schedule, introduced by the 52nd Constitutional Amendment (1985) and interpreted in Kihoto Hollohan (1992), continues to govern disqualification on the ground of defection. Nabam Rebia inserts a non-derogable impartiality rule: a Speaker facing removal cannot adjudicate disqualification petitions.
Practice Implications
For counsel advising on floor-test and government-formation writs
- Anchor on Article 163(1) aid-and-advice default — plead that any Governor's action without a constitutional carve-out requires cabinet advice.
- Invoke S.R. Bommai (1994) 3 SCC 1 floor-test doctrine — the floor of the House is the forum for majority testing, not Raj Bhavan.
- Urgent relief should be pleaded with specificity — seek mandamus to convene a floor test within a fixed short window.
For counsel drafting Tenth Schedule disqualification challenges
- Front-load Speaker-impartiality grounds — where a removal motion was pending, invoke Nabam Rebia to void the Speaker's order.
- Place Kihoto Hollohan on the quasi-judicial nature — to ground the natural-justice argument against biased adjudication.
- Track the pending 7-Judge reference — note but preserve the client's rights under the operative 5-judge ruling.
For counsel responding to gubernatorial advancement or dissolution of Assembly
- Plead mala fides with contemporaneous evidence — preserve correspondence, cabinet-note rejections, communication between Raj Bhavan and rebel groups.
- Use Article 212 carve-out to open judicial review — frame the challenge as a constitutional breach, not a procedural irregularity.
- Seek interim stay of Assembly proceedings — file a WP(C) under Article 32 seeking status-quo orders preserving the democratically elected government.
Twin-citation formula
In any Governor-Legislature or Tenth Schedule matter, pair Nabam Rebia with:
- Shamsher Singh v. State of Punjab, (1974) 2 SCC 831 — foundational on aid-and-advice.
- Kihoto Hollohan v. Zachillhu, 1992 Supp (2) SCC 651 — Speaker's quasi-judicial role.
- S.R. Bommai v. Union of India, (1994) 3 SCC 1 — federalism and floor-test doctrine.
Downstream applications and interpretations
- Shamsher Singh v. State of Punjab, (1974) 2 SCC 831 — applied for the aid-and-advice default rule.
- Kihoto Hollohan v. Zachillhu, 1992 Supp (2) SCC 651 — applied for Speaker's quasi-judicial Tenth Schedule role.
- S.R. Bommai v. Union of India, (1994) 3 SCC 1 — applied for federalism and limits of Governor's power.
- Rameshwar Prasad v. Union of India, (2006) 2 SCC 1 — referenced on Governor's Article 356 misuse.
Practitioner FAQ
Is Nabam Rebia still the governing authority on Speaker impartiality under the Tenth Schedule?
Yes, pending further clarification. The 5-judge Larger Bench ruling in Nabam Rebia v. Deputy Speaker remains the operative law on the Speaker's quasi-judicial role, including the principle that a Speaker facing a removal motion cannot adjudicate Tenth Schedule disqualification petitions. The question has been referred to a 7-Judge Constitution Bench for reconsideration; until that Bench rules, Nabam Rebia governs.
When can a Governor exercise discretion under Article 163(2) after Nabam Rebia?
Only where the Constitution expressly so provides. Typical examples are inviting the leader of a pre-poll coalition or the single-largest party to form government where no party has a clear majority (Article 164), referring a Bill for the President's consideration (Article 200), and recommending President's Rule under Article 356 on advice. Nabam Rebia rules out discretionary session-advancement for political ends.
What should counsel plead in a writ challenging gubernatorial action post-Nabam Rebia?
Plead three limbs: (i) the absence of an express constitutional carve-out for the action, invoking Article 163(1) aid-and-advice default; (ii) mala fides or procedural unfairness to trigger Article 212 judicial review; and (iii) where a floor test is in issue, invoke S.R. Bommai, (1994) 3 SCC 1 and the principle that elected-government displacement without constitutional process is unconstitutional.
Does Nabam Rebia affect post-election government formation?
Yes, indirectly. By reaffirming Shamsher Singh v. State of Punjab, (1974) 2 SCC 831 and confining Article 163(2), Nabam Rebia disciplines the Governor's choice of whom to invite to form government. The Governor must ordinarily invite the leader of the party or coalition commanding a majority; where no clear majority emerges, the Governor retains narrow discretion cabined by constitutional convention and the floor-test principle in S.R. Bommai.
How should MLAs challenge a Speaker's disqualification order after Nabam Rebia?
Challenge through an Article 226 writ to the High Court and, as an alternative, an Article 32 writ to the Supreme Court. Plead Nabam Rebia on two fronts: (i) the Speaker's lack of impartiality if a removal motion was pending; and (ii) the Article 212 reach of judicial review where the disqualification order suffers from constitutional infirmity. Place Kihoto Hollohan on the quasi-judicial nature of the Speaker's role.
Does Article 212 still bar judicial review of procedural irregularities?
Yes. Article 212 continues to bar enquiry into the validity of legislative proceedings on grounds of mere procedural irregularity. Nabam Rebia's carve-out is limited to constitutional violations, mala fide intent and procedural unfairness amounting to constitutional breach. Counsel must carefully plead constitutional breach — not just procedural error — to displace Article 212.
