When six Shiv Sena (UBT) MPs reportedly moved towards Eknath Shinde’s faction this month, it was not merely another episode in Maharashtra’s long-running political drama. It was the latest reminder that India’s anti-defection framework is facing a crisis of relevance. Similar reports of unrest within the Trinamool Congress, earlier splits in the Shiv Sena and Nationalist Congress Party (NCP), and recurring allegations of political engineering have revived an uncomfortable question: if the anti defection law India was created to stop political switching, why are defections still reshaping governments and parliamentary numbers across the country?
The answer lies in a contradiction that has become increasingly visible over the last few years. The law continues to exist, but politicians have learned how to work around it. Rather than eliminating defections, the anti defection law India has changed the way defections happen, encouraging larger and more organised political realignments instead of individual acts of rebellion.
Why the anti defection law India was introduced
The anti-defection law was introduced through the 52nd Constitutional Amendment in 1985 after years of political instability. During the 1960s and 1970s, governments frequently collapsed because legislators switched parties after elections, often in exchange for political rewards. The phrase “Aaya Ram, Gaya Ram” became symbolic of an era where elected representatives changed loyalties with remarkable ease.
To address this problem, Parliament added the Tenth Schedule to the Constitution. Under the law, MPs and MLAs can be disqualified if they voluntarily leave their party or vote against the party whip on important matters. The objective was straightforward: protect electoral mandates and ensure political stability.
For a time, the law appeared successful. Individual defections declined and governments became harder to topple through small-scale political manoeuvring. But politics, as it often does, adapted faster than the law itself.
How politicians learned to navigate the anti defection law India
The biggest weakness in the anti defection law India lies in the merger provision. While an individual legislator risks disqualification, a group that crosses the two-thirds threshold can avoid many of the consequences associated with defection.
This provision was originally intended to facilitate genuine political mergers. Instead, critics argue that it has become the preferred route for organised defections.
The Shiv Sena split is perhaps the most prominent example. In 2022, Eknath Shinde led a rebellion involving a substantial number of Shiv Sena MLAs. The move ultimately resulted in the fall of the Uddhav Thackeray government and triggered a legal battle that continues to shape Maharashtra politics today. The Election Commission later recognised Shinde’s faction as the official Shiv Sena, while court challenges remain pending.
A similar pattern emerged within the Nationalist Congress Party when Ajit Pawar broke away from Sharad Pawar’s camp. More recently, reports of defections within opposition parties, including the Trinamool Congress and Aam Aadmi Party, have further highlighted how political actors continue to exploit gaps within the system.
The result is a strange reality. The law that was meant to stop political switching often allows it when enough legislators move together.
Why the anti defection law India matters beyond Maharashtra
The latest Shiv Sena defections are not just about Maharashtra. They are also about parliamentary power.
Every MP who changes sides affects the balance of power in Parliament. The ruling NDA remains short of the numbers required for a two-thirds majority in the Lok Sabha, making every additional seat politically valuable. Recent defections from opposition parties have therefore become part of a larger national story involving constitutional amendments, delimitation debates, and future legislative reforms.
This explains why political defections have become more strategic. They are no longer simply about changing governments in individual states. They are increasingly linked to broader efforts to strengthen parliamentary numbers at the national level.
For opposition parties, the consequences are equally significant. Losing MPs means losing committee representation, speaking time, bargaining power, and political relevance. In an era of coalition politics, even a handful of defections can reshape national political calculations.

The real problem with the anti defection law India
The deepest challenge facing the anti defection law India is not legal but democratic.
Many of the legislators currently switching camps were elected on platforms that explicitly opposed the parties they are now supporting. Voters cast ballots based on alliances, manifestos, and political commitments made during elections. When elected representatives later change sides, the question becomes unavoidable: who owns the mandate—the voter, the party, or the legislator?
The anti-defection law attempted to answer that question by prioritising party discipline. Yet today’s political reality suggests that the law has not fully achieved its objective. Instead of preventing defections, it has encouraged politicians to defect in larger groups capable of meeting legal thresholds.
The ongoing Shiv Sena crisis, the NCP split, and recent reports of opposition defections all point towards the same conclusion. The anti defection law India is not failing because politicians are openly breaking it. It is struggling because political actors have learned how to operate within its rules while producing outcomes that appear contrary to its original purpose.
Four decades after its introduction, the law remains one of the most important safeguards in India’s constitutional system. But unless its loopholes and ambiguities are addressed, political defections are likely to remain a defining feature of Indian democracy rather than a problem of the past.
