Political Shifts Across India

In recent times, significant political shifts have been observed across India, including the loss of control of the Trinamool Congress (TMC) by Mamata Banerjee in West Bengal. In Maharashtra, six out of nine MPs from Uddhav Thackeray's Shiv Sena (UBT) have joined Eknath Shinde's faction, while in Delhi and Punjab, seven MPs from the Aam Aadmi Party (AAP) have switched allegiance to the BJP. This wave of party switching raises critical questions regarding the anti-defection law, particularly in Goa, where a pivotal case is pending in the Supreme Court.

Recent Developments in Party Alliances

In April, seven out of ten Rajya Sabha MPs from AAP, led by Raghav Chadha, defected to the BJP. Following the election results in May, the BJP formed its first government in West Bengal, leading to 20 out of 28 TMC MPs initiating discussions to merge with a lesser-known party called the Nationalist Citizens Party of India (NCPI). Concurrently, six out of nine Lok Sabha MPs from Shiv Sena (UBT) have decided to join Shinde's faction.

Understanding the Anti-Defection Law

The anti-defection law in India was enacted in 1985, disqualifying any legislator who voluntarily resigns from their party or fails to adhere to the party's directives. Initially, the law allowed two exceptions: splits and mergers. However, due to frequent misuse of the split provision, it was abolished in 2003, leaving only the merger exception under Paragraph 4 of the Tenth Schedule. This paragraph has two parts: the first part protects legislators when their original party merges with another, while the second part stipulates that such a merger is only valid if at least two-thirds of the members of the legislative party agree.

The Core Debate on Mergers

The central issue revolves around whether these two parts of the law should be interpreted together or separately. If read together, the original party must first merge with another party, and then two-thirds of the legislative members must confirm this merger. Conversely, if interpreted separately, only a two-thirds majority of MPs is required for a merger, without needing a decision from the original party.
