SC to consider urgent hearing of Sena (UBT) plea against merger
Have enough grounded facts (article + Wikipedia/general on Tenth Schedule + news background on prior Sena SC litigation). Writing the note now.
1. At a Glance
- The Shiv Sena (UBT) has moved the Supreme Court challenging Lok Sabha Speaker Om Birla's approval of six of its nine MPs "merging" with the rival Shiv Sena (Eknath Shinde faction) [S1].
- Core constitutional issue: whether a "merger" under the Tenth Schedule (anti-defection law) can be validly claimed by legislators alone, without a merger of the original political party [S1][S2].
- Tests the Speaker's quasi-judicial role in defection/merger adjudication and its timing ahead of the Monsoon Session of Parliament [S1].
- High relevance for GS-II (Parliament, anti-defection law, judicial review of Speaker's decisions).
2. Why in the News
- On Tuesday (21 July 2026), the Supreme Court, under Chief Justice of India Surya Kant, agreed to urgently list Shiv Sena (UBT)'s plea against Speaker Om Birla's recognition of six of its nine Lok Sabha MPs as having merged with the Shinde-led Shiv Sena [S1].
- Senior advocate Devadatt Kamat, for Sena (UBT), orally mentioned the matter, stating the party's functioning in Parliament has come to a "standstill" and sought urgent hearing before the Monsoon Session [S1].
3. Background & Evolution
- 1985: 52nd Constitutional Amendment Act inserted the Tenth Schedule into the Constitution, creating the anti-defection framework [S2].
- 2003: 91st Constitutional Amendment removed the "split" exception (one-third defection protection) and tightened the "merger" exception to require two-thirds of a legislature party's members to merge with another party, and mandated the merger be of the original political party, not merely the legislature party [S2].
- 2022: Shiv Sena split into two factions — Uddhav Balasaheb Thackeray (UBT) group and Eknath Shinde group (now Deputy CM of Maharashtra); Election Commission later allotted the "Shiv Sena" name and symbol to the Shinde faction [S1][S3].
- 2024 onward: Sena (UBT) had earlier separately litigated at the Supreme Court over Speaker-related disqualification and floor-leader disputes involving both the Maharashtra Assembly Speaker and Lok Sabha Speaker [S3].
- 2026: Fresh dispute arises specifically over Lok Sabha Speaker Om Birla's approval of a Lok Sabha-level "merger" of six of Sena (UBT)'s nine MPs with the Shinde faction [S1].

5. Multi-Dimensional Analysis
Legal / Constitutional - Turns on interpretation of para 4 of the Tenth Schedule — merger protection applies only when the original political party merges, not when a legislature-party faction unilaterally claims merger [S1][S2]. - Raises the recurring question of Speaker's impartiality and delay in adjudicating defection/merger disputes, and the scope of judicial review over Speaker's decisions (cf. Kihoto Hollohan v. Zachillhu, 1992, principle that Speaker acts as tribunal).
Governance / Ethical - Kamat's submission that the merger exception, "originally meant to safeguard legislators' rights of expression and intra-party dissent," has "metamorphosed into a cover for horse-trading" — highlights misuse of anti-defection exceptions nationally [S1]. - Tests institutional neutrality of presiding officers in politically charged floor-strength disputes.
Administrative - Directly affects a party's functional recognition in Parliament — floor leader status, whip issuance, committee allocations — since Sena (UBT) says its "functioning as a political party in Parliament has come to an absolute standstill" [S1].
Historical - Continues the post-2022 pattern of intra-Shiv Sena legal battles spanning the Maharashtra Assembly Speaker's ruling, Election Commission's symbol allotment, and now the Lok Sabha Speaker's merger approval [S1][S3].
6. Recent Developments (last 12-18 months)
- 21 July 2026: SC agrees to urgently consider Sena (UBT)'s plea against Speaker Om Birla's merger approval, ahead of Monsoon Session [S1].
- Prior (2024): SC separately heard Sena (UBT) pleas on disqualification of Shinde-faction MLAs and questioned delays by the Maharashtra Speaker [S3].
7. Prelims Hooks
- Tenth Schedule was inserted by the 52nd Constitutional Amendment Act, 1985.
- The 91st Amendment (2003) removed the "split" defense and fixed the merger threshold at two-thirds of the legislature party.
- A valid merger under the Tenth Schedule requires merger of the original political party, not just the legislative wing.
- Current CJI mentioned in this matter: Surya Kant.
- Lok Sabha Speaker in this dispute: Om Birla.
- Shiv Sena (UBT) has 9 Lok Sabha MPs, of whom 6 were held to have merged with the Shinde faction.
- Eknath Shinde is the Deputy Chief Minister of Maharashtra.
- The landmark case on Speaker's disqualification powers under the Tenth Schedule is Kihoto Hollohan v. Zachillhu (1992).
- Anti-defection disputes are adjudicated in the first instance by the presiding officer (Speaker/Chairman) of the House.
- Shiv Sena split into two factions in 2022.
8. Mains Relevance
- GS-II: Parliament and State legislatures — structure, functioning, conduct of business; powers, privileges of Speaker; anti-defection law and its issues.
- Possible question stems: 1. "Critically examine the merger exception under the Tenth Schedule and whether it has become a tool for legitimizing defection rather than preventing it." 2. "Discuss the scope of judicial review over decisions of the Speaker acting as a tribunal under the Tenth Schedule, with reference to recent Supreme Court interventions." 3. "Should adjudicatory powers under the anti-defection law be vested in an independent body rather than the presiding officer? Examine with recent examples."

10. Common Errors / Trap Areas
- Confusing the "split" exception (removed in 2003) with the still-existing "merger" exception — only merger is valid protection now.
- Assuming a legislature-party-level merger suffices — the Tenth Schedule requires merger of the original political party.
- Mixing up this Lok Sabha Speaker (Om Birla) dispute with the separate, earlier Maharashtra Assembly Speaker (Rahul Narwekar) disqualification case — they are distinct proceedings.
- Assuming CJI Surya Kant's bench has ruled on merits — as of the article, the Court only agreed to urgently list/consider the plea, no final order yet.
- Forgetting that the anti-defection law is in the Tenth Schedule, not a separate standalone Act.
