Constitution of India
Article 180: Power of the Deputy Speaker or other person to perform the duties of the office of, or to act as, Speaker
Part VI — The States (Chapter III — The State Legislature, Sub-heading: Officers of the State Legislature)
Clause (1) — Vacancy in the office of Speaker
WHAT IT SAYS: When the office of Speaker is vacant, the Deputy Speaker performs the Speaker's duties; if both offices are vacant, the Governor appoints a member of the Assembly to act as Speaker. WHAT IT MEANS: Ensures legislative proceedings are never paralysed due to a leadership vacuum — the Deputy Speaker automatically steps in, and as a last resort the Governor can appoint any MLA. KEY DOCTRINE: Doctrine of Continuity of Presiding Authority — the Legislature must always have a constitutionally authorised presiding officer to maintain order, conduct business, and certify bills.
Clause (2) — Absence of Speaker from a sitting
WHAT IT SAYS: During any sitting from which the Speaker is absent, the Deputy Speaker acts as Speaker; if he too is absent, the person determined by the Assembly's rules of procedure presides; if no such person is present, the Assembly itself determines who shall act as Speaker. WHAT IT MEANS: Creates a three-tier succession hierarchy for temporary absences — (i) Deputy Speaker, (ii) person per rules of procedure, (iii) person chosen by the House — ensuring the Assembly is always competently presided over. KEY DOCTRINE: Doctrine of Self-Regulation of Legislature — empowers the Assembly to internally manage its own presiding arrangements without executive interference during temporary absences.
Constitutional Inspiration
SOURCE(S): 1. United Kingdom — Westminster Parliamentary Convention (Speaker of the House of Commons) Original provision: The UK House of Commons has Deputy Speaker and Chairman of Ways and Means who preside in the Speaker's absence under standing orders. What India kept: The principle of a succession hierarchy for presiding officers to ensure uninterrupted legislative proceedings. 2. Article 95 of the Indian Constitution (Lok Sabha equivalent) Original provision: Article 95 provides identical Speaker-succession arrangements for the Lok Sabha, mirroring Article 180 for state legislatures. What India kept: Near-identical language to ensure federal symmetry and uniform parliamentary practice. INDIA'S SPECIFIC ADAPTATIONS: 1. Governor's Appointment Power (Clause 1) — In vacancy cases, the Governor (not the Assembly) appoints a member; this addressed the concern that a newly constituted Assembly may not yet have elected presiding officers. 2. Three-Tier Hierarchy in Clause 2 — India codified a written layered succession (Deputy Speaker → Rules of Procedure → Assembly choice), whereas the UK relies on unwritten convention; this was necessary because India adopted a written Constitution. 3. Applicability to State Legislatures — The framers replicated the Lok Sabha model at the state level to ensure uniformity in a federal system where 28+ states each needed identical procedural safeguards.
Constituent Assembly Debate
DEBATED ON: 2 June 1949 (CAD Volume VIII) DRAFT ARTICLE: Draft Article 159 of the Draft Constitution corresponded to present Article 180. KEY SPEAKERS: 1. Dr. B.R. Ambedkar (Chairman, Drafting Committee) — Moved Draft Article 159 as a procedural provision mirroring the already-adopted Article 78 (now Article 95) for the Lok Sabha; no controversy arose. 2. Mr. Naziruddin Ahmed (West Bengal) — Proposed minor textual amendments (substituting 'a' for 'another') for linguistic precision; the amendment was negatived. 3. T.T. Krishnamachari (Madras) — Moved a new Article 159-A (now Article 181) to prevent the Speaker from presiding during his own removal proceedings, referencing the need for clause (2) of Article 159 (now 180) to apply in such sittings. MAJOR DISAGREEMENTS: 1. No substantive disagreement — Article 159 was adopted without major debate, as the parallel provision for Parliament (Draft Article 78) had already been accepted. 2. The only proposal debated was whether the removal threshold should be 'all the then members' vs. 'members present and voting' under related Article 158 (now 179) — the Assembly chose 'all the then members.' FINAL OUTCOME: Draft Article 159 was adopted without amendment on 2 June 1949; the related Article 159-A was also adopted on the same day. AMBEDKAR'S KEY QUOTE (if available): No specific standalone quote on Draft Article 159 is recorded, as the article was moved and adopted without debate.
Landmark Judgments
LANDMARK JUDGMENTS: 1. Nabam Rebia v. Deputy Speaker, Arunachal Pradesh (2016) — 5-judge Bench held that when a notice for Speaker's removal is pending, the Speaker cannot exercise disqualification powers under the Tenth Schedule; also clarified that the Governor cannot advance Assembly sessions without the aid and advice of the Chief Minister, indirectly affirming the scope and limits of acting-Speaker authority under Art. 180. 2. Kihoto Hollohan v. Zachillhu (1992) — Upheld the Speaker's role as tribunal under the Tenth Schedule but struck down Paragraph 7 (judicial review ouster clause); reinforced that provisions like Art. 180 ensure procedural continuity when the Speaker cannot preside. 3. Rameshwar Prasad v. Union of India (2006) — Declared dissolution of Bihar Assembly unconstitutional; reaffirmed the Speaker's constitutional role in maintaining the Assembly's integrity, which Art. 180 supports by ensuring a presiding officer is always available. NOTABLE DISSENTS (if any): 1. Justice L.M. Sharma & Justice J.S. Verma in Kihoto Hollohan (1992) — Dissented on vesting disqualification powers in the Speaker, arguing the Speaker lacks the independence of an adjudicatory authority; this has implications for the scope of acting-Speaker powers under Art. 180. SCHOLARS & JURISTS: 1. M.P. Jain (Indian Constitutional Law) — Notes that Art. 180 mirrors Art. 95 and establishes a vital principle that the Legislature must never lack a competent presiding officer. 2. D.D. Basu (Commentary on the Constitution of India) — Observes that a member acting as Speaker under Art. 180 has only procedural authority and cannot exercise quasi-judicial constitutional powers like anti-defection disqualification unless expressly authorised.
