What Happened

  • The Rajya Sabha Chairman accepted a merger petition filed by seven members from AAP's Rajya Sabha group into the Bharatiya Janata Party, raising BJP's Rajya Sabha strength to 113.
  • The seven members who merged are: Raghav Chadha, Ashok Kumar Mittal, Harbhajan Singh, Sandeep Kumar Pathak, Vikramjit Singh Sahney, Swati Maliwal, and Rajinder Gupta.
  • AAP had 10 members in the Rajya Sabha before the merger; seven constitutes exactly two-thirds of ten, meeting the mathematical threshold under the Tenth Schedule.
  • AAP separately submitted a petition to the Rajya Sabha Chairman seeking disqualification of the seven members, arguing the merger does not fulfil the legal requirements under Paragraph 4 of the Tenth Schedule.
  • Constitutional experts and legal commentators have questioned whether the merger passes the full legal test, given that AAP as a political party continues to exist and has not merged with BJP at the organisational level.

Static Topic Bridges

The Tenth Schedule and Anti-Defection Law

The Tenth Schedule was inserted into the Constitution by the Constitution (Fifty-Second Amendment) Act, 1985. It was enacted to address the phenomenon of "aaya ram gaya ram" politics — the practice of legislators switching parties frequently for personal gain. It applies to both Houses of Parliament and State Legislatures.

  • Paragraph 2: A member is disqualified if they voluntarily give up membership of their original political party or vote/abstain contrary to party directions.
  • Paragraph 4 (Merger Exception): A member is not disqualified where the merger involves not less than two-thirds of the members of the legislature party. The merger must be of the original political party — not just the legislature wing — with another party.
  • Paragraph 6: The Speaker/Chairman of the House is the final authority to decide disqualification petitions; this decision is subject to judicial review.
  • 91st Amendment Act, 2003: Deleted the "split" exemption (which previously protected one-third of legislators splitting off), leaving merger as the only valid exception to disqualification.
  • The Tribunal-like role of the Speaker/Chairman has been criticised since they are often partisan figures.

Connection to this news: The Chairman's acceptance of the merger invoked Paragraph 4. The contested legal question is whether seven legislators moving to another party while their parent party continues to exist constitutes a "merger of the original political party" as required by the Schedule.


The "Twin Test" for a Valid Merger

Constitutional jurisprudence has developed a two-limb test for a merger under Paragraph 4 to be valid, distinguishing between a mere bloc migration and a genuine party merger.

  • Limb 1 — Merger of the original party: The original political party itself must merge with the other party at the organisational level. A faction of the legislature party moving does not, by itself, constitute merger of the original party.
  • Limb 2 — Two-thirds of the legislature party: At least two-thirds of the members of the legislature party must support the merger.
  • Both limbs must be satisfied. Meeting only the two-thirds numerical threshold without an organisational merger at the party level does not satisfy Paragraph 4.
  • Courts, including the Supreme Court in Kihoto Hollohan v. Zachillhu (1992), upheld the Tenth Schedule's validity while affirming judicial review of the Speaker's/Chairman's decisions.

Connection to this news: Critics argue that only Limb 2 (two-thirds numerically) was met here, while Limb 1 (organisational merger of AAP with BJP) was not. AAP continues to function as a party in Delhi and Punjab, making this a contested application of Paragraph 4.


Role of the Rajya Sabha Chairman

The Vice President of India serves as the ex-officio Chairman of the Rajya Sabha. Under the Tenth Schedule, the Chairman has quasi-judicial authority to decide disqualification petitions.

  • The Chairman's decision is not subject to judicial review while the proceedings are ongoing; courts can review only after the final order (as settled in Kihoto Hollohan).
  • The Chairman must act judicially — in accordance with principles of natural justice — when deciding disqualification petitions.
  • There is no fixed timeframe within which the Chairman must decide such petitions; this has been a persistent criticism of the anti-defection mechanism.

Connection to this news: The Chairman's acceptance of the merger petition is itself the subject of AAP's counter-petition for disqualification. The outcome of that petition will determine whether the seven members can retain their seats.

  • Rajya Sabha composition post-merger (reported): BJP: 113 seats; AAP: 3 seats (remaining after 7 merged).
  • Landmark case: Kihoto Hollohan v. Zachillhu (1992) — Supreme Court upheld Tenth Schedule's constitutionality; finality clause of Speaker/Chairman's order partially struck down as unconstitutional, enabling judicial review.
  • Chairman's role: Vice President of India is ex-officio Rajya Sabha Chairman (Article 64 and Article 89).
  • Constitutional articles: Articles 102(2) and 191(2) trigger disqualification; Tenth Schedule specifies the grounds.
