This landmark judgment by a three-judge Bench of the Supreme Court addresses the fundamental tension between the existential right to a clean environment and the aspirational right to sustainable development. The core issue revolved around the legality of granting ex post facto (retroactive) environmental clearances (ECs) to projects that commenced construction or operation without obtaining prior EC as mandated by the Environment Impact Assessment (EIA) Notification, 2006. Reviewing conflicting precedents and previous rulings (including the recall of Vanashakti-I), the Court meticulously evaluated the statutory powers of the Central Government under the Environment (Protection) Act, 1986. The Supreme Court held that while the prior EC regime under the 2006 Notification is strictly mandatory, the Central Government possesses the delegated legislative competence under Section 3 of the 1986 Act to enact narrow, time-bound, and exceptional amnesty measures like the 2017 Notification. However, routine administrative instructions functioning as a perpetual regularisation mechanism—such as the 2021 Office Memorandum (OM)—are ultra vires the Act and violate Articles 14 and 21 of the Constitution. To prevent widespread disruption to vital public infrastructure projects, the 2021 OM was quashed prospectively under Article 142.
- Mandatory Nature of Prior EC Regime: The requirement for a prior environmental clearance under the 2006 Notification is non-negotiable and rooted in the precautionary principle; starting a project without it violates environmental law and implies the restoration of the status quo ante, closure, or demolition, alongside civil penalties under Section 15 of the 1986 Act (as amended by the Jan Vishwas Act, 2023).
- Validity of the 2017 Notification: The 2017 Notification is held to be a valid, narrowly tailored, and time-bound piece of delegated legislation enacted under Section 3 of the 1986 Act read with Section 21 of the General Clauses Act. Because it was restricted to a closed class of existing violators and a strict six-month window, it satisfies the tests of reasonable classification and proportionality.
- Invalidity of the 2021 Office Memorandum (OM): The 2021 OM is declared an invalid administrative instruction that unlawfully attempts to supplant delegated legislation by establishing a permanent, open-ended regularisation scheme without a cut-off date, failing both proportionality and Article 14 standards.
- Prospective Quashing and Protection of Pending Applications: Invoking Article 142 to protect supervening public interests (such as public hospitals, medical colleges, and infrastructure projects) and resolve legal confusion, the 2021 OM is quashed prospectively.
- Final Directions on EC Status:
- Existing ECs already granted under the 2017 Notification and 2021 OM remain valid unless independently challenged on merits.
- Pending applications under these instruments must be taken to their logical conclusion in accordance with law.
- No fresh or future applications for ex post facto ECs under administrative orders will be entertained, and the government is strictly restrained from issuing similar executive instruments going forward.
