Speaker's Approval of MPs' Merger Challenged: Tenth Schedule Merger Clause Under Scrutiny
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.
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.
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.
