Vanashakti v. Union of India
"A 2026 Supreme Court ruling (2026 INSC 761) that struck down the government's 2021 scheme of indefinite ex-post-facto environmental clearances as an invalid use of an Office Memorandum."
Vanashakti v. Union of India (2026 INSC 761), pronounced on 29 July 2026 by a bench led by Chief Justice of India Surya Kant with Justices Joymalya Bagchi and Vipul Pancholi, struck down a 2021 Ministry of Environment, Forest and Climate Change (MoEFCC) Office Memorandum that had allowed projects begun without prior environmental clearance to apply for retrospective ('ex-post-facto') regularisation on an essentially indefinite, open-ended basis. The Court held that the EIA Notification, 2006, issued under Section 3 of the Environment (Protection) Act, 1986, mandates prior environmental clearance before a covered project commences, and that a mere internal Office Memorandum cannot create an exception to this statutory prior-clearance regime, since only a properly issued statutory notification (delegated legislation) can do so. The ruling invoked the precautionary principle and the polluter pays principle, and drew on an earlier line of Supreme Court scrutiny of similar 2017 and 2021-vintage 'regularisation window' notifications. The judgment did not impose an absolute, blanket bar: it left open a narrow path for the government to issue a properly framed, time-bound statutory exception in exceptional circumstances (a 'supervening public interest' test), while foreclosing an open-ended administrative amnesty available to any violator by default. Its effect is prospective, so clearances already granted under the struck-down 2021 OM (and an earlier 2017 notification) remain valid unless individually challenged.
A high-value, current 2026 case testing GS2 (delegated legislation, judicial review, separation of powers) and GS3 (environmental clearance framework, precautionary/polluter-pays principles); likely to be cited alongside older EIA jurisprudence in both Prelims case-matching and Mains analytical questions.
- 1 Citation: 2026 INSC 761; pronounced 29 July 2026.
- 2 Bench: CJI Surya Kant, Justices Joymalya Bagchi and Vipul Pancholi.
- 3 Struck down: MoEFCC Office Memorandum, 2021, permitting indefinite ex-post-facto environmental clearances.
- 4 Core holding: an Office Memorandum cannot override the mandatory prior-clearance regime under the EIA Notification, 2006.
- 5 Doctrines invoked: precautionary principle, polluter pays principle.
- 6 Left open: a narrow, time-bound statutory exception on a 'supervening public interest' test, not a blanket bar.
- 7 Effect is prospective; earlier clearances under the 2017/2021 instruments remain valid unless separately challenged.
Vanashakti v. Union of India is now the leading precedent cited whenever a government proposes any form of retrospective regularisation for projects that began without statutorily required prior clearance.
