The dramatic exodus of Raghav Chadha and six fellow AAP Rajya Sabha MPs to the BJP has thrust a long‑dormant private member’s bill back into the national conversation. The bill, proposed by Chadha himself in 2022, sought to toughen India’s anti‑defection law—and, in doing so, could have made such a split far more difficult, if not legally unviable.

Under the Tenth Schedule, also known as the anti‑defection law, a group of MPs can “merge” with another party if at least two‑thirds of their original party’s strength in the House moves along with them. AAP has 10 Rajya Sabha MPs, so two‑thirds works out to seven. Chadha led six others across the floor, meeting the threshold exactly and framing their move as a bulk merger rather than individual defection.

That technical reading has allowed the group to avoid immediate disqualification—at least for now—while legal experts and opposition parties hotly debate whether this kind of coordinated, publicly announced shift is what the “merger” clause was ever meant to protect. Many argue it has turned a safeguard into a loophole that enables organised floor‑crossing.

In August 2022, Raghav Chadha introduced a private member’s bill in the Rajya Sabha aimed at tightening the existing anti‑defection framework. His proposal would have raised the threshold from two‑thirds to three‑fourths of a party’s legislative strength. For AAP’s current Rajya Sabha tally, that would mean eight MPs, not seven, would be required to legally “merge” with another party.

The bill also sought to bar lawmakers who switch parties from contesting elections for six years, in addition to imposing stricter procedural checks such as requiring them to appear before the House Chair within a week of withdrawing support. While the bill was never passed or seriously taken up by the government, it laid out a version of the law that would have made large‑scale exits far costlier and more politically sensitive.

If Chadha’s proposed three‑fourths bar had become law, his operation would have required one more rebel MP to cross over legally. That single extra seat could have altered the internal calculations, communication strategy, and even the optics of the move. The six‑year contest ban would have forced defectors to consider not only their immediate future but also their long‑term electoral prospects. The threat of such a bar might have pushed the BJP or the dissenting MPs toward a different kind of negotiation—or even toward abandoning the mass‑exodus model altogether. Instead, the unchanged Tenth Schedule allowed a clean, seven‑MP exit that stripped AAP of a significant chunk of its Rajya Sabha presence while leaving the defecting MPs technically within the law for the time being.

The AAP split has reignited criticism of the anti‑defection law’s merger clause, with legal experts and opposition leaders arguing that it has been turned into a tool for institutionalised defection rather than a curb on horse‑trading. Some point to the Goa MLAs’ case and other precedents as evidence that the clause is being stretched in ways that dilute its original intent.

There is growing speculation that the Supreme Court may soon revisit how “merger” is interpreted under the Tenth Schedule, especially as examples like the AAP‑BJP move raise questions about the balance between party discipline and individual conscience. In the long run, the episode could revive calls for reforms similar to those Chadha once championed—higher thresholds, longer bans on contesting, and tighter timelines for challenge procedures.

The immediate fallout is a weakened presence in the Rajya Sabha at a time when the party is navigating post‑Delhi politics and trying to stabilise its position in states like Punjab. The internal rift symbolised by Chadha’s exit also raises questions about how the party manages rising‑star MPs and ideological disagreements before they escalate into open splits. The episode has become a textbook example of how constitutional design can quietly shape even the most dramatic political dramas. A bill that sat on paper for years now looks like a missed inflection point—one that, had it been enacted, might have redrawn the contours of India’s anti‑defection landscape and possibly prevented this AAP fracture before it began.
