Exit of AAP MPs puts spotlight on Defection Law’s merger provision

A political rupture sets off a constitutional debate. Then, Raghav Chadha and six Rajya Sabha MPs break from Aam Aadmi Party and announce a “merger” with the Bharatiya Janata Party. As a result, India’s anti-defection law faces a sharp and immediate test.

The rebels rely on Paragraph 4 of the Tenth Schedule. They argue that two-thirds support inside a legislature party protects them from disqualification. However, the claim raises a core question. Can legislators create a valid merger on numbers alone, or must the original political party also approve the move?

Party offices in Delhi see tense scenes. AAP workers gather, hold placards, and accuse the MPs of betrayal. In contrast, BJP supporters welcome the shift and call it a political endorsement. Meanwhile, legal teams on both sides prepare for a prolonged fight before constitutional authorities.

The legal framework comes into focus. India added the Tenth Schedule through the 52nd Constitutional Amendment in 1985 to curb defections. The law disqualifies members who leave their party or defy its whip. Earlier, it allowed “split” and “merger” as exceptions. Later, the 91st Amendment removed the split route after repeated misuse. Today, only the merger exception remains.

Paragraph 4 sets two conditions. First, the original political party must merge with another party. Second, at least two-thirds of the legislature party must support that merger. On a plain reading, both conditions must operate together. Yet, past decisions often highlight the numbers inside the House and downplay the party-level decision.

The present dispute sharpens the gap between text and practice. The seven MPs meet the two-thirds mark in the Rajya Sabha. Still, AAP as an organisation has not approved any merger. Therefore, critics argue that the MPs cannot claim protection by acting alone.

Judicial guidance adds weight to this view. In the Subhash Desai vs Principal Secretary Governor of Maharashtra ruling, the Supreme Court of India draws a clear line between a political party and its legislature wing. The court states that legislators cannot act independently of the party in key decisions. This reasoning suggests that a merger also needs party consent.

At the same time, conflicting rulings create uncertainty. In a Goa case, the Bombay High Court accepts a merger based on two-thirds legislative support alone. That view now faces challenge in the Girish Chodankar vs Speaker Goa Legislative Assembly matter. The final outcome may settle the law.

The immediate decision rests with the Rajya Sabha chairman. He must examine disqualification petitions and decide whether the MPs qualify for protection or face removal. Until then, a grey zone persists. The MPs may align with another party, yet they still carry obligations to their original party.

The episode acts as a constitutional stress test. If numbers alone validate a merger, the law may enable defections it aims to prevent. If party approval remains essential, the framework may regain its original purpose. Either way, the controversy pushes the issue toward a decisive judicial answer.
