AAP Rajya Sabha MPs Claim Merger with BJP — Legal Implications under 10th Schedule

On Friday, 24 April 2026 , Rajya Sabha MP Raghav Chadha of the AAP announced that he and six other AAP members in the Upper House had merged with the BJP . He argued that the move would not trigger disqualification because it would fall under the exception provided in the 10th Schedule . The announcement has sparked a fresh debate on the scope of the anti‑defection law and the procedural requirements for a valid party merger. Key Developments Chadha claimed that "2/3rd of the AAP members in the Rajya Sabha have merged with the BJP". He cited Paragraph 4 of the anti‑defection law as a defence against disqualification. The Supreme Court’s judgment in Subhash Desai emphasised that a merger must originate from the original political party, not merely the legislative party. The Bombay High Court (Goa Bench) earlier upheld a merger of Congress MLAs with the BJP on the basis that a two‑thirds majority of the legislative party suffices, creating a conflicting precedent. Important Legal Provisions Paragraph 2 of the 10th Schedule makes voluntary surrender of party membership a ground for disqualification. Paragraph 4 provides an exception: a member is not disqualified if the "original political party" merges with another party and the member acts in accordance with that merger. Sub‑paragraph (2) stipulates that the merger is deemed valid only when at least two‑thirds of the members of the legislative party agree to it. The Supreme Court, in Subhash Desai , warned that allowing a legislative party to merge independently would "sever the umbilical cord" between legislators and their parent party, defeating the purpose of the anti‑defection law. UPSC Relevance Understanding the nuances of the anti‑defection law is essential for GS‑2 (Polity) questions on parliamentary ethics, party discipline, and constitutional safeguards. Candidates should note: The distinction between a political party and its legislative party is pivotal in interpreting merger provisions. Supreme Court pronouncements, such as in Subhash Desai , carry greater authority than High Court rulings. The pending Supreme Court review of the Goa High Court’s decision (SLP(c) 5256/25) will likely clarify the operative test for a valid merger, a development worth tracking for future exam questions. Way Forward Given the conflicting judgments, the Supreme Court is expected to resolve the issue. Until a definitive ruling emerges, the following steps are advisable for legislators and parties: Any merger should be formally announced by the national leadership of the original party. Obtain the consent of at least two‑thirds of the legislative party members across all houses to satisfy Paragraph 4(2). Maintain clear documentation of the merger process to defend against disqualification petitions. For UPSC aspirants, monitoring the Supreme Court’s eventual decision will provide insight into the balance between party autonomy and legislative stability, a core theme in Indian constitutional law.
