No More Green Clearance by Office Memo: Supreme Court Shuts the Door on Retrospective Environmental Approvals

Can the government allow a project to get environmental clearance after construction has already started, simply by issuing an administrative order? The Supreme Court answered this question on 29 July 2026 in Vanashakti v. Union of India, quashing a 2021 Office Memorandum that had allowed exactly this kind of after the fact approval. This case has an interesting back and forth history across three different Benches, which makes it a rich topic for judiciary exam preparation.

In this blog, we trace the journey of this litigation, explain what the Court finally decided, and break down why the reasoning matters for administrative and environmental law.

Key Details at a Glance

Background: What the 2021 Office Memorandum Did

The Ministry of Environment, Forest and Climate Change had issued an Office Memorandum on 7 July 2021, laying down a Standard Operating Procedure for identifying and dealing with cases where projects had started construction or operations without first obtaining the mandatory prior environmental clearance under the Environmental Impact Assessment Notification, 2006. In simple terms, this Office Memorandum created a system that let such projects apply for clearance after the fact, effectively regularising violations of the prior clearance rule.

Vanashakti, along with other environmental groups, challenged this Office Memorandum, arguing that it undermined the entire purpose of requiring environmental clearance before a project begins. The whole idea of prior clearance is to assess environmental impact before any damage is done, and allowing after the fact approval effectively rewarded project proponents who skipped this step.

The Back and Forth Litigation History

•      In May 2025, a Bench of Justice Abhay S. Oka and Justice Ujjal Bhuyan called such post-facto clearances a gross illegality and barred their grant going forward.

•      In November 2025, a larger Bench comprising then Chief Justice B.R. Gavai, Justice K. Vinod Chandran and Justice Ujjal Bhuyan recalled the May 2025 judgment, with Justice Bhuyan dissenting. The majority felt the earlier ruling had not fully accounted for existing precedent taking a more calibrated view of post-facto clearances, and it flagged concerns about the disruptive effect on public projects worth thousands of crores.

•      The matter was then reheard afresh before a Bench led by Chief Justice Surya Kant, with judgment reserved on 1 April 2026 and finally delivered on 29 July 2026.

What the Supreme Court Finally Held

The Bench of Chief Justice Surya Kant, Justice Joymalya Bagchi and Justice Vipul Pancholi held that the Central Government does have the power to provide for post-facto environmental clearances, but only through a valid statutory notification issued under Section 3 of the Environment (Protection) Act, 1986, not through a mere administrative Office Memorandum.

Justice Bagchi, delivering the operative part of the judgment, observed that the prior clearance regime under the 2006 EIA Notification is mandatory unless it is amended through a statutory notification, and that an Office Memorandum simply does not qualify as a statutory notification. The Court described the 2021 Office Memorandum as supplanting an earlier executive regime through an administrative order, which it held to be impermissible.

The Bench held that the Office Memorandum failed the tests of proportionality and reasonableness, and accordingly declared it ultra vires the Environment (Protection) Act, 1986. However, the Court gave its ruling prospective effect, meaning that clearances already granted under the earlier regime, including under the 2017 notification and the 2021 Office Memorandum, remain protected, though they can still be individually challenged.

The Court also directed that no further applications will be entertained under either the 2017 notification or the 2021 Office Memorandum, effectively shutting the door on these specific regularisation mechanisms going forward. At the same time, the ruling leaves open a narrower path, that the government may, in exceptional circumstances and in the larger public interest, provide for post-facto clearances through a properly issued statutory notification.

Why This Case Matters

•      It draws a clear line between what can be done through delegated statutory rule making and what cannot be achieved through a mere administrative circular.

•      It reinforces that the prior environmental clearance requirement is the cornerstone of India's Environmental Impact Assessment framework, not a formality that can be diluted administratively.

•      The litigation history itself, spanning three Benches over more than a year, is a good illustration of how larger Benches can recall and revisit earlier rulings within the Supreme Court's own hierarchy.

•      The prospective nature of the ruling shows how courts sometimes balance strict legal principle against the practical disruption that a fully retrospective ruling could cause to large infrastructure investments.
