Six Shiv Sena MPs Defect to Eknath Shinde Faction – Implications for Anti‑Defection Law and NDA Strength

Overview The political scene in India is witnessing a fresh wave of defections. Six Shiv Sena (UBT) MPs are moving to the Eknath Shinde faction, which now represents exactly two‑thirds of the party's Lok Sabha strength . This shift is being framed as a merger under the Tenth Schedule . The move raises serious questions about the effectiveness of the anti‑defection framework and its impact on the ruling NDA in Parliament. Key Developments Six Shiv Sena (UBT) MPs seek to join the Eknath Shinde faction, meeting the two‑thirds threshold for a legal merger . The 2003 amendment to the anti-defection law removed the “split” provision, leaving only the merger route. Similar defections have occurred in the Trinamool Congress (TMC) (20 of 28 Lok Sabha MPs) and the Aam Aadmi Party (AAP) (Rajya Sabha members dropping from 10 to 3). Three TMC Rajya Sabha members — Sukhendu Sekhar Ray , Sushmita Dev and Prakash Chik Baraik — have resigned, further weakening opposition numbers. The Supreme Court has yet to rule on whether a merger can involve only the legislature party without the parent party. Important Facts The anti‑defection law disqualifies a member who voluntarily resigns from his party or defies a party whip during a vote. Under the current law, a disqualification is avoided only when at least two‑thirds of a party’s legislators agree to merge with another party. Because the constitutional amendment threshold is two‑thirds, the NDA’s present strength (even after defections) is still short of the numbers needed to amend the Constitution. Pending Supreme Court judgments on the interpretation of the merger clause have allowed parties to exploit the loophole, making the Tenth Schedule appear ineffective. Relevance for UPSC Understanding these defections is crucial for GS Paper‑2 (Polity) . The case illustrates how constitutional provisions (the Tenth Schedule ) interact with judicial interpretation ( Supreme Court ) and political strategy. It also highlights the importance of the NDA 's parliamentary arithmetic for passing constitutional amendments . Way Forward Legislature may consider amending the anti‑defection law to close the merger loophole, possibly by requiring the parent party’s consent. The Supreme Court should expedite pending judgments to provide clarity. Parliamentary committees could review the impact of defections on democratic stability and recommend safeguards. Political parties need to strengthen internal discipline and address grievances to reduce engineered defections.
