SC to consider Sena (UBT) plea against Speaker’s approval of MPs’ ‘unilateral merger’
The Lok Sabha Speaker approved the merger of six Members of Parliament belonging to one faction of a regional party with another faction of the same party, formalising a change in the House strength of both factions.
The matter was mentioned before a Bench headed by the Chief Justice of India seeking urgent listing of a plea challenging the Speaker's approval.
The plea contends that a group of legislators cannot secure protection from disqualification merely by mustering a two-thirds majority among themselves, without an antecedent merger of the original political party itself.
The Supreme Court did not grant urgent listing at the first mentioning; the matter remains pending consideration.
Tenth Schedule (Anti-Defection Law) — The Merger Exception
The Tenth Schedule was inserted into the Constitution by the 52nd Constitutional Amendment Act, 1985, to curb defections by disqualifying legislators who voluntarily give up membership of their party or vote/abstain against party directions. Paragraph 4 of the Schedule carves out an exception for genuine mergers, so that a merger is not treated as disqualifiable defection.
Key Details
- Originally (1985), a split of one-third of a party's legislators was also protected; the 91st Constitutional Amendment Act, 2003 deleted this "split" defence entirely and raised the merger threshold to two-thirds.
- Paragraph 4(1) requires two conditions in sequence: (a) a merger of the original political party with another political party, and (b) at least two-thirds of the members of the legislature party having agreed to the merger.
- The disputed legal question is whether condition (a) — merger of the original party itself, as distinct from just its legislature wing — must be independently established, or whether securing two-thirds legislator consent is sufficient by itself.
- Disqualification proceedings under the Tenth Schedule are decided by the Speaker/Chairman of the House concerned, acting in a quasi-judicial capacity.
The core of the challenge is precisely this twin-test question — whether the Speaker's approval improperly treated two-thirds legislator agreement as itself constituting a "merger," without a corresponding merger of the original party organisation.
Kihoto Hollohan v. Zachillhu (1992) — Judicial Review of Speaker's Decisions
Kihoto Hollohan v. Zachillhu is the landmark five-judge Constitution Bench ruling that decided the constitutionality of the Tenth Schedule itself.
Key Details
- Decided on 18 February 1992, the Court upheld the Tenth Schedule's validity by a 3:2 majority but struck down Paragraph 7, which had sought to bar judicial review of the Speaker's/Chairman's decisions on disqualification.
- The Court held that the Speaker acts as a tribunal while deciding defection matters, and such quasi-judicial orders are subject to judicial review on grounds of malafide, perversity, or violation of natural justice — though review is generally limited until the Speaker's order is actually made (subject to narrow exceptions).
- The ruling preserved legislative autonomy in day-to-day proceedings while ensuring that constitutional questions of defection do not escape all external scrutiny.
The present challenge to the Speaker's approval of the MPs' merger is itself an exercise of the judicial review that Kihoto Hollohan preserved — without that 1992 ruling, such a plea could not be entertained by a court at all.
Distinguishing "Political Party" from "Legislature Party"
The Tenth Schedule uses two distinct terms that this dispute turns on: the "original political party" (the organisational party structure) and the "legislature party" (the party's elected members sitting in a particular House).
Key Details
- A merger under Paragraph 4 is only protected if it is a merger of the original political party; the legislature party's agreement is treated as a ratifying step of two-thirds, not a substitute for the party-level act.
- This distinction has arisen in prior defection disputes, including proceedings before Assembly Speakers in Maharashtra concerning rival factions of the same undivided party, where the question of which faction represents the "real" political party was similarly contested.
- The Election Commission of India, not the Speaker, is the authority that decides disputes over which faction is entitled to a party's name and symbol under the Election Symbols (Reservation and Allotment) Order, 1968 — a related but procedurally separate question from the Speaker's Tenth Schedule determination.
The plea's central argument — that the Speaker treated the legislature party's two-thirds consent as a proxy for the "original party" merger — squarely engages this organisational-versus-legislative distinction.
- Constitutional basis of the anti-defection law: Tenth Schedule, inserted by the 52nd Amendment Act, 1985.
- Merger threshold under Paragraph 4: at least two-thirds of the legislature party's members, following the 91st Amendment Act, 2003 (which removed the earlier one-third "split" protection).
- Landmark case on Speaker's quasi-judicial role and judicial review: Kihoto Hollohan v. Zachillhu (1992), decided 3:2, striking down Paragraph 7.
- Authority deciding disqualification under the Tenth Schedule: the Speaker (Lok Sabha) or Chairman (Rajya Sabha)/Speaker of the Assembly concerned.
- Separate authority for party name/symbol disputes: Election Commission of India, under the Election Symbols (Reservation and Allotment) Order, 1968.
