Raghav Chadha joins BJP: Can he be disqualified from Rajya Sabha? What the anti-defection law says

What Happened

• Seven Rajya Sabha members announced their exit from their parent party and merger with another party, invoking the merger exception under Paragraph 4 of the Tenth Schedule to avoid disqualification.
• The move clears the two-thirds threshold of the legislative party's strength in the Rajya Sabha, which is the constitutionally required minimum for a valid merger under anti-defection law.
• A counter-petition was filed arguing that the move is a colourable defection and not a genuine merger, as the parent political party itself has not merged at the national level.
• The episode reignites a longstanding constitutional debate: does Paragraph 4 require a merger of the political parties themselves, or only a two-thirds agreement among the legislature party members?

Paragraph 4 of the Tenth Schedule — The Merger Exception

Paragraph 4 of the Tenth Schedule carves out the principal exception to disqualification: a merger. Under this provision, members who agree to a merger are not disqualified — neither those who support the merger nor those who remain with the original party.

Text of the provision (Paragraph 4): A member shall not be disqualified where their original political party merges with another political party, and: - (a) The member and any other members of their original legislative party have become members of the other party or a new party formed by the merger; or - (b) They have not accepted the merger and opted to function as a separate group.

The merger is valid if and only if at least two-thirds of the members of the legislature party have agreed to such merger.

"Legislature Party" vs. "Original Political Party" — A Critical Distinction

The Tenth Schedule distinguishes sharply between the legislature party and the original political party. This distinction is central to the current controversy.

• Legislature party: All elected members of a House belonging to one political party at a given point in time.
• Original political party: The political party at the national/organisational level to which the member belongs.

Why this matters: Paragraph 4 requires that at least two-thirds of the legislature party (not the full membership of the political party nationwide) agree to the merger. However, Paragraph 4(1) also specifies that the "original political party" itself must merge with another party. This creates a critical ambiguity:

• Conjunctive reading: A valid merger requires BOTH (i) the political party at the national level to formally merge, AND (ii) at least two-thirds of the legislature party to agree. Under this view, individual legislators cannot trigger the merger exception without a genuine national-level party merger.
• Disjunctive reading: A two-thirds agreement among legislators of the legislature party is itself sufficient to constitute a "deemed merger."

Constitutional scholars and courts have debated this distinction extensively. The conjunctive reading is considered more rigorous and harder to abuse; the disjunctive reading is more permissive and has been criticised as enabling engineered defections.

91st Constitutional Amendment Act, 2003 — Strengthening the Merger Bar

The 91st Amendment significantly tightened the merger exception. Before this amendment, defections by as few as one-third of a legislative party could qualify as a merger. The amendment raised this to two-thirds, making it harder to engineer "mergers" for political convenience.

Key provisions of the 91st Amendment: - Raised merger threshold from one-third to two-thirds (amending Paragraph 4 of the Tenth Schedule) - Inserted Articles 75(1A) and 164(1A): Capped the size of the Council of Ministers at 15% of the lower house strength (to discourage coalition-building through defections) - Inserted Article 75(1B): A Minister disqualified under the Tenth Schedule cannot be reappointed until re-elected

Key Legal Precedents on Mergers and Defections

Kihoto Hollohan v. Zachillhu (1992) - Five-judge Constitution Bench upheld the Tenth Schedule as constitutionally valid. - Struck down Paragraph 7 (which barred judicial review of the presiding officer's decisions) as violating the basic structure. - Held: Presiding officer's decision is quasi-judicial and subject to judicial review post-final order.

Ravi S. Naik v. Union of India (1994) - The Supreme Court held that "voluntarily giving up membership" is broader than formal resignation; it can be inferred from conduct. - A member who acts against the party even without a written resignation can be disqualified.

Balchandra L. Jarkiholi v. B.S. Yediyurappa (2011) — Karnataka Speaker case - Highlighted procedural issues in disqualification proceedings. - Courts reiterated that presiding officers must act fairly and within a reasonable time.
