Shiv Sena (UBT) MPs’ likely switch: Can they escape anti-defection law, avoid disqualification?

The Anti-Defection Law, introduced via the 52nd Amendment Act in 1985, aims to curb political defection driven by power and monetary allurements. It provides grounds for the disqualification of an elected member, primarily under Paragraph 2, which includes voluntarily giving up membership or voting contrary to party whips. However, the law provides specific exemptions. Crucially, the 91st Amendment Act of 2003 deleted Paragraph 3, which previously protected a 'split' (where one-third of members defected) from disqualification. Currently, Paragraph 4 is the primary defense, stating disqualification doesn't apply if an 'original political party' merges with another, and at least two-thirds of the legislature party agrees to this merger. The current dispute centers on whether this two-thirds requirement applies solely to the legislators or mandates a merger at the organizational level of the political party itself. The 2023 Subhash Desai v. Principal Secretary judgment is pivotal here, as the Supreme Court ruled that a 'split' is no longer a valid defense and emphasized that determining the 'real political party' shouldn't merely rely on legislative majority but must consider the party's organizational structure and constitution.

The controversy highlights significant challenges in the role of the Speaker or Chairman in adjudicating defection cases. The Speaker acts as a tribunal under the Tenth Schedule, subject to judicial review (the power of courts to examine the constitutionality of legislative or executive actions) as established in the landmark Kihoto Hollohan v. Zachillhu case. The current scenario demonstrates how the Speaker's interpretation of a 'merger' can dramatically influence political stability. The Bombay High Court's ruling in the Girish Chodankar case (2022) allowed a group of MLAs to merge based on the two-thirds rule, effectively treating the legislative group's decision as a deemed merger. However, constitutional experts argue this interpretation is flawed, contending that a foundational merger of the original political party is a prerequisite before the two-thirds legislative strength test can be applied. This ongoing legal ambiguity regarding the interpretation of Paragraph 4 creates a volatile environment where the Speaker's partisan leanings might influence crucial decisions, undermining the very intent of the Anti-Defection Law.

From a legal standpoint, the interpretation of 'voluntarily giving up membership' is also critical. As clarified in Rajendra Singh Rana v. Swami Prasad Maurya (2007), a member need not formally resign; their conduct, such as engaging in anti-party activities or defying whips, can be construed as voluntarily giving up membership, leading to disqualification. In the context of the Shiv Sena (UBT) MPs, their absence from party meetings despite a whip could trigger disqualification proceedings. The legal battle hinges on whether these MPs can successfully invoke the merger protection under Paragraph 4 before disqualification proceedings conclude. If they form a separate group without merging, they face imminent disqualification under Paragraph 2. The Supreme Court's impending final decision on the interpretation of 'merger' will be a landmark ruling, clarifying whether legislative factions can unilaterally decide to merge or if the organizational mandate of the original political party is legally supreme.
