Anti-Defection Law in Focus: Legal Ambiguities in Party Mergers

27 Apr 2026

The recent defection of seven Rajya Sabha MPs from the Aam Aadmi Party (AAP), including Raghav Chadha, to the Bharatiya Janata Party (BJP) raises concerns over the applicability of the Tenth Schedule and potential disqualification.

Background of Anti-Defection Law

The Anti-Defection Law aims to prevent political instability caused by frequent party switching.

Rationale Behind Anti-Defection Law

To curb “Aaya Ram Gaya Ram” Politics: The 10th Schedule was added via the 52nd Amendment (1985) during the Rajiv Gandhi government to curb “Aaya Ram Gaya Ram” politics.
Initially, it allowed for a “split” (1/3rd members) and a “merger” (2/3rd members).

Key Points

Removal of Split Clause: The 91st Amendment eliminated the “split” provision (Paragraph 3) because it was too easy to manipulate. Currently, only a merger (Paragraph 4) provides an exemption from disqualification.
The Paragraph 4 Debate: A merger is valid if at least two-thirds of the legislative party members agree to switch. However, a legal nuance exists between:
- Consecutive Reading: Both the original political party must merge, and 2/3rd of the legislative members must agree.
- Disjunctive Reading: If 2/3rd of the legislative members agree, it is considered a valid merger regardless of the original party’s stance.
Judicial Precedents:
- Rajendra Singh Rana vs. Swami Prasad Maurya: The Supreme Court favored consecutive reading, introducing the “Two-Head Theory” (an individual cannot wear the hats of two parties).
  - Prevents misuse of the merger clause.
- Goa Case (2019/2022): The Bombay High Court relied on disjunctive reading, validating mergers based solely on the 2/3rd legislative threshold.

Challenges

Authority with Presiding Officer: The power to decide disqualification cases under the Anti-Defection Law rests with the Speaker of the Lok Sabha and the Chairman of the Rajya Sabha.
Possibility of Political Bias: Since presiding officers are usually affiliated with the ruling party or coalition, there is a risk of biased decision-making.
Delay in Adjudication: Prolonged delays in deciding defection cases reduce the effectiveness of the law, as outcomes often come after political changes have already occurred.

Way Forward

Need for Legal Clarity: There is a need for clear judicial or legislative interpretation of Paragraph 4 of the Tenth Schedule to remove ambiguity.
Independent Decision-Making Mechanism: An independent and neutral body should be established to adjudicate defection cases to ensure fairness and impartiality
Time-Bound Process: The adjudication process must be made time-bound so that decisions are delivered promptly and remain relevant.

Conclusion

The core debate remains whether the 10th Schedule protects the political party’s integrity or the will of the legislative majority. A balanced approach is needed to ensure that anti-defection laws serve their long-term purpose in Indian polity without being subverted by legal loopholes.
