SC stays Mukul Roy’s disqualification from Bengal Assembly
UPSC Study Note: SC Stays Mukul Roy's Disqualification from Bengal Assembly
1. At a Glance
- The Supreme Court of India stayed a Calcutta High Court order disqualifying Mukul Roy as a West Bengal MLA under the Tenth Schedule (anti-defection law) of the Constitution. [S1][S2]
- The case turns on critical constitutional questions: the evidentiary standard for proving defection, the Speaker's adjudicatory role, and the admissibility of electronic evidence under Section 65B of the Indian Evidence Act. [S3]
- Relevant across GS-II (Polity — Parliament, State Legislatures, Judiciary) and GS-III (Digital governance/evidence). The intersection of AI-generated/manipulated digital media with constitutional proceedings makes this a landmark contemporary hook.
- Highlights the perennial tension between legislative autonomy (Speaker as sole arbiter) and judicial review of disqualification decisions.
2. Why in the News
- 16 January 2026: The Supreme Court, led by Chief Justice of India Surya Kant, stayed the Calcutta High Court order that had disqualified Mukul Roy from the West Bengal Legislative Assembly. [S1][S3]
- The CJI's bench made a pointed observation: "In this AI era, anybody's face can be used in a video" — questioning the reliability of a video clipping of a press conference as sole proof of defection. [S3]
- The Court found, prima facie, that the High Court had applied the wrong standard — "preponderance of probability" — instead of a stricter evidentiary test for a disqualification proceeding. [S3]
- The petition was filed by Subhranshu Roy on behalf of his father Mukul Roy; opposed by counsel for West Bengal Opposition Leader Suvendu Adhikari (BJP). [S3]
3. Background & Evolution
| Year | Event |
|---|---|
| 1985 | Tenth Schedule added to the Constitution via the 52nd Constitutional Amendment Act, instituting the anti-defection law. |
| 1992 | Kihoto Hollohan v. Zachillhu — Supreme Court upheld constitutional validity of the Tenth Schedule but held that Speaker's decisions are subject to judicial review (not immune). [S4] |
| 2021 (June) | Mukul Roy, elected as BJP MLA from Krishnanagar Uttar constituency in the 2021 West Bengal elections, publicly re-joined Trinamool Congress (TMC). Disqualification petition filed against him. [S1][S2] |
| 2022 | West Bengal Assembly Speaker rejected the disqualification petition, finding insufficient material to establish defection. [S1][S2] |
| 2023–25 | Calcutta High Court Division Bench set aside the Speaker's order; matter remanded; HC subsequently disqualified Mukul Roy under Tenth Schedule. [S1][S2] |
| Jan 2026 | Supreme Court stays HC disqualification order; raises issues of evidentiary standard and AI-manipulated media. [S1][S3] |
4. Core Static Facts
The Anti-Defection Law — Tenth Schedule: - Added by 52nd Constitutional Amendment, 1985; operative under Articles 102(2) and 191(2) of the Constitution. - Applies to both Parliament and State Legislatures. - Grounds for disqualification: (a) Voluntarily giving up party membership; (b) Voting/abstaining contrary to party direction without prior permission. - Exception: Merger of at least two-thirds of party's legislature members (post-91st Amendment, 2003). - Decision-maker: Speaker (Lok Sabha/State Assembly) or Chairman (Rajya Sabha/State Council) — functions as a quasi-judicial authority. - Judicial review: Available, as held in Kihoto Hollohan (1992), but Courts intervene only after the Speaker decides (except in cases of mala fide or procedural violation).
Section 65B, Indian Evidence Act, 1872: - Governs admissibility of electronic records (emails, videos, social media content) as evidence. - Requires a certificate from a responsible official of the computer/device attesting to the authenticity of the electronic record. - Standard established by the Supreme Court in Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020): Section 65B certificate is mandatory, not optional, for secondary electronic evidence.
Key Actors in this case: - Mukul Roy — BJP-turned-TMC politician; MLA from Krishnanagar Uttar, West Bengal - Suvendu Adhikari — West Bengal Opposition Leader (BJP); petitioner seeking disqualification - CJI Surya Kant — presided over the Supreme Court bench that granted the stay - West Bengal Assembly Speaker — original adjudicatory authority
5. Multi-Dimensional Analysis
Legal / Constitutional
- The case tests whether "preponderance of probability" (civil standard) can govern disqualification under the Tenth Schedule, or whether a stricter evidentiary threshold is required, given the constitutional consequences (loss of elected membership). [S3]
- Section 65B compliance is a mandatory procedural safeguard; the HC's apparent non-application of this requirement is the central ground for the SC stay. [S3]
- Tension between the Speaker's exclusive jurisdiction under the Tenth Schedule and High Court's power of judicial review — the HC's exercise of original disqualification (rather than remand) is itself legally contested.
- The Kihoto Hollohan principle limits intervention to post-decisional review; the HC proceeding here went further.
Governance / Ethical
- The Speaker's dual role — presiding officer and party member — creates an inherent conflict of interest in deciding defection cases. Supreme Court itself has suggested an independent tribunal (retired SC judge) as a substitute. [S4]
- Politicisation of disqualification proceedings: The West Bengal Speaker (TMC-aligned) had earlier refused to disqualify Mukul Roy (who had returned to TMC), raising questions of partisan adjudication.
- The judgment highlights the abuse potential of manufactured/AI-generated digital evidence in constitutional proceedings — a novel governance risk.
Scientific / Technological
- CJI Surya Kant's AI deepfake observation signals judicial recognition of the threat of AI-manipulated media in legal proceedings.
- Section 65B was designed for an era of authentic digital records; its adequacy against deepfakes, AI-generated videos, and social media screenshots is now a live policy question.
- Evidentiary reform may be needed: the Bharatiya Sakshya Adhiniyam, 2023 (BSA) — which replaced the Indian Evidence Act — contains similar electronic evidence provisions (Section 63) whose adequacy against AI manipulation remains untested.
Political / Historical
- Mukul Roy was a founding member of TMC, later joined BJP (2017), and re-joined TMC (2021) — illustrating the phenomenon of serial defection that the Tenth Schedule was meant to deter.
- The case reflects West Bengal's politically charged legislative environment, where ruling party loyalty, Speaker partisanship, and judicial intervention frequently intersect.
6. Recent Developments (Last 12–18 Months)
- November 2025: Calcutta High Court disqualified Mukul Roy as West Bengal MLA under the Tenth Schedule, based on video evidence of his alleged participation in a TMC press conference. [S2]
- 16 January 2026: Supreme Court stays the HC disqualification order; CJI Surya Kant raises concerns about AI-manipulated video evidence and non-compliance with Section 65B. [S1][S3]
- 2025 (Telangana): In Padi Kaushik Reddy v. State of Telangana, SC criticised Telangana Speaker for delay and set a 3-month deadline for deciding disqualification petitions — reinforcing judicial oversight of Speaker's anti-defection role. [S4]
7. Prelims Hooks
- The anti-defection law is contained in the Tenth Schedule of the Constitution, inserted by the 52nd Constitutional Amendment Act, 1985.
- Articles 102(2) and 191(2) provide for disqualification of MPs and MLAs respectively on grounds of defection.

- In Kihoto Hollohan v. Zachillhu (1992), the Supreme Court upheld the Tenth Schedule but ruled that Speaker's decisions are subject to judicial review.
- Section 65B of the Indian Evidence Act mandates a certificate of authenticity for admissibility of electronic records as secondary evidence — ruled mandatory (not optional) in Arjun Panditrao Khotkar (2020).
- The 91st Constitutional Amendment (2003) raised the threshold for a valid merger from one-third to two-thirds of the legislature party.
- The Bharatiya Sakshya Adhiniyam, 2023 (BSA) replaced the Indian Evidence Act; its Section 63 is the equivalent of the old Section 65B on electronic evidence.
- Mukul Roy was elected as BJP MLA from Krishnanagar Uttar constituency in the 2021 West Bengal elections.
- The West Bengal Assembly Speaker rejected the initial disqualification petition against Mukul Roy (circa 2022) on grounds of insufficient evidence.

- Chief Justice of India Surya Kant presided over the SC bench that granted the stay in January 2026.
- The disqualification petition in the Mukul Roy case was originally filed by Suvendu Adhikari, the West Bengal Opposition Leader (BJP).
- Under the Tenth Schedule, "voluntarily giving up membership" of a party is a ground for disqualification even without a formal resignation from the party (as held by SC in multiple cases).

10. Common Errors / Trap Areas
- Wrong Amendment Year: The Tenth Schedule was inserted by the 52nd Amendment (1985), NOT the 42nd or 44th Amendment (common mix-up). The 91st Amendment (2003) modified it.
- Speaker vs. Governor: Disqualification under the Tenth Schedule is decided by the Speaker (not the Governor), and at the Centre by the Lok Sabha Speaker / Rajya Sabha Chairman.
- Section 65B is mandatory, not optional: Post Arjun Panditrao Khotkar (2020), the SC clarified that the 65B certificate cannot be waived; earlier cases (Shafhi Mohammad, 2018) that called it optional are overruled. Aspirants often cite the older position.
- "Preponderance of probability" vs. criminal standard: In constitutional/quasi-criminal proceedings like defection, courts have not settled on a uniform standard — assuming the civil standard applies is the trap the HC fell into, as the SC observed.
- Mukul Roy's party trajectory: He was originally a TMC founder-member → BJP (2017) → back to TMC (2021). The disqualification relates to the BJP-to-TMC leg. Confusing the direction of defection is a common factual error.
