Lok Sabha Speaker To Hear Shiv Sena (UBT) & TMC Rebel MPs Merger Cases

Lok Sabha Speaker Om Birla is set to hear petitions from both Shiv Sena (Uddhav Balasaheb Thackeray) and Trinamool Congress regarding rebel MPs' party affiliation and potential mergers/splits, invoking provisions of the Tenth Schedule of the Indian Constitution (Anti-Defection Law).

Background: The Tenth Schedule (Anti-Defection Law) was added in 1985 to prevent political defections and floor-crossing. However, the law contains a 'merger clause' (Paragraph 3, now deleted/modified) that previously allowed one-third of party MPs to merge with another party without triggering disqualification. Recent deletions and modifications have created ambiguity about legitimate party mergers versus defection.

Key facts: (1) Shiv Sena (UBT) alleges 9 MPs offered ₹15 crore to defect to Shinde faction; (2) TMC faces 20 MPs seeking to merge with NCPI (National Congress Party of India); (3) NCPI claims post-merger it becomes largest parliamentary force from West Bengal; (4) Provides judicial scrutiny mechanism; (5) Sets precedent for anti-defection jurisprudence.

Why it matters: Core constitutional question on political stability, party democracy, and state governance. Shiv Sena split could reshape Maharashtra politics; TMC split weakens West Bengal opposition to TMC dominance. Raises questions about merger provision's legitimacy and protection of party symbols/ideology.

Exam angle: Anti-Defection Law (Tenth Schedule), Paragraph 3 deletion implications, merger vs. defection distinction, Lok Sabha Speaker's constitutional role, and party democracy principles. Frequently asked in UPSC GS-II (Constitution & Polity).
