Centre resumes appraising pending post facto green clearances after Supreme Court ruling
Can a project that broke the law be cleared afterwards? The Centre reopens pending cases but bars new ones.
Published 3 October 2026. Written by Pratidin from the reports linked at the end; every fact checked by a separate review before publishing. How we work
The Union Ministry of Environment, Forest and Climate Change (MoEFCC) has directed central and State expert bodies to resume appraising 'post facto' environmental clearance (EC) proposals, The Indian Express reported on 3 October 2026. A post facto EC is an approval given to a project that started work, expanded or modernised without first obtaining the environmental clearance that the law requires. The directive is narrow. Only proposals that were pending, rejected or returned will be processed, and no new post facto proposals will be accepted. Projects that already hold a post facto clearance remain valid.
The trigger is the Supreme Court's ruling of 29 July 2026 in Vanashakti v Union of India. The Court upheld the Ministry's 2017 notification, which had opened a one-time, six-month window under the Environment Impact Assessment (EIA) Notification, 2006 for projects already in violation to apply for clearance. It quashed a 2021 Office Memorandum (an executive instruction) on the post facto mechanism, but allowed pending applications to be processed. It stressed that prior environmental clearance remains mandatory unless the rules are formally amended through the legal process. The ruling ends a long dispute: in May 2025 the Court had struck down the entire post facto mechanism, and later recalled that judgment on review, in proceedings that included a petition by the Confederation of Real Estate Developers' Association of India (CREDAI).
The EIA Notification, 2006, issued under the Environment (Protection) Act, 1986, requires listed projects to obtain clearance before any work begins, after screening, scoping, public consultation and appraisal by expert committees. The idea is to judge harm before it happens. Supporters of the post facto route argue that tearing down completed buildings and plants wastes resources, and that a closed window with penalties brings violators under regulation. Critics argue that any route to approve projects after the fact rewards violation and empties the 'prior' in prior clearance of meaning, a view the Supreme Court itself took in Alembic Pharmaceuticals v Rohit Prajapati (2020), when it called ex post facto clearances contrary to the precautionary principle and set aside a 2002 circular that had allowed them. The Ministry's decision to accept no new proposals is meant to keep the window closed.

Recurring theme: Environmental impact assessment, environmental clearance and judicial oversight of environmental regulation
- How to use this
Use it to set out the core design of the EIA Notification, 2006 and the principle of prior clearance, the benchmark against which any newer draft's dilutions should be compared.
- The EIA Notification, 2006, issued under the Environment (Protection) Act, 1986, requires listed projects to get clearance before any work begins, after screening, scoping, public consultation and appraisal.
- Under the 2006 framework, a 2017 notification opened a one-time, six-month window for violating projects; in Vanashakti v Union of India (29 July 2026) the Supreme Court upheld it but quashed a 2021 Office Memorandum.
- The Court held prior environmental clearance mandatory unless rules are formally amended, so any regime easing post facto approval must be tested against this and Alembic Pharmaceuticals (2020).
- How to use this
Use the post facto clearance litigation as an example of how court challenges, not only appraisal committees, have decided what EIA permits for projects built without prior clearance.
- Vanashakti v Union of India (29 July 2026): the Supreme Court upheld the 2017 one-time window, quashed the 2021 Office Memorandum and held prior clearance mandatory unless rules are formally amended.
- Alembic Pharmaceuticals v Rohit Prajapati (2020): the Court called ex post facto clearances contrary to the precautionary principle and set aside a 2002 circular allowing them.
- Show that litigation cuts both ways: the May 2025 ruling striking down the post facto mechanism was recalled on review, in proceedings including a petition by the real estate body CREDAI.
- How to use this
Use it to open by explaining why EIA must precede clearance: assessment after construction can only legitimise or mitigate harm, not prevent it.
- The EIA Notification, 2006 requires clearance before any work begins, after screening, scoping, public consultation and appraisal by expert committees, so that harm is judged before it happens.
- In Alembic Pharmaceuticals v Rohit Prajapati (2020) the Supreme Court called ex post facto clearances contrary to the precautionary principle, which applies with force to large polluting plants.
Mains practice question
"Ex post facto environmental clearance defeats the very purpose of environmental impact assessment." Critically examine this statement in the light of the Supreme Court's 2026 ruling in Vanashakti v Union of India. (250 words)
Model answer
Environmental impact assessment (EIA) judges a project's harm before work begins. A post facto clearance approves a project after it has started without one. In Vanashakti v Union of India (29 July 2026), the Supreme Court upheld the 2017 one-time window but quashed the 2021 Office Memorandum, and the Centre has now resumed appraising only pending cases.
Why post facto clearance undercuts EIA
- Prevention lost: the EIA Notification, 2006, under the Environment (Protection) Act, 1986, requires screening, scoping, public consultation and appraisal before work.
- Public hearing becomes a formality once the damage is done.
- Moral hazard: repeated windows teach developers to build first and seek approval later.
- Precedent: in Alembic Pharmaceuticals v Rohit Prajapati (2020) the Supreme Court said ex post facto clearance derogates from the fundamental principles of environmental law and is contrary to the precautionary principle.
The case for a limited window
- Sunk costs: demolishing completed projects wastes public and private resources.
- Regulation over limbo: a window with penalties and remediation brings violators under scrutiny.
- Closed door: the Ministry will accept no new post facto proposals, and the Court held prior clearance mandatory unless the rules are formally amended.
Way forward
- Make penalties exceed the gains from violation, and require restoration of damage.
- Strengthen State-level monitoring so violations are caught early.
- Publish all post facto decisions to allow public scrutiny.
- Apply the precautionary and polluter pays principles in every appraisal.
Conclusion
A strictly one-time window can clear a backlog, but only firm enforcement of prior clearance keeps EIA meaningful.
The basics
Why this matters
Environmental clearance is the gate every large project must pass. The question in this story is simple: what happens to a project that walked through without stopping at the gate? The answer touches environmental law, the role of courts in checking executive action, and the balance between development and prevention.
What a clearance is
Under the Environmental Impact Assessment Notification, 2006, listed projects must get approval before work begins. Expert appraisal committees, at the Centre and in the States, examine the proposals.
- 1ScreeningAn initial check of the proposed project
- 2ScopingFix the terms of reference for the impact study
- 3Public consultationHold a public hearing and invite written responses
- 4AppraisalAn expert committee examines the study and recommends approval or rejection
What post facto means
A Post facto environmental clearance is granted after a project has already started or expanded without approval. It turns the process upside down: the impact is assessed after it has happened.
- Approval before work begins
- Public hearing can change the project
- Follows the precautionary principle
- Approval after work has started
- Damage may already be done
- Now limited to pending, rejected or returned proposals
How the courts got here
The dispute was settled in Vanashakti v Union of India, which went through a full judgment, a recall and a final ruling.
- 2006EIA Notification requires prior environmental clearance
- 2017Ministry opens a one-time, six-month window for projects in violation
- 2021Ministry issues an Office Memorandum on the post facto mechanism
- May 2025Supreme Court strikes down the entire post facto mechanism
- 29 July 2026After recalling that judgment, the Court upholds the 2017 notification and quashes the 2021 memorandum
- October 2026Centre resumes appraising pending, rejected or returned post facto proposals
The principle underneath
The whole system rests on the Precautionary principle: where harm may be serious, act before it happens, not after.
The takeaway
The window is now closed to new applicants. Whether it stays closed will depend on how strictly prior clearance is enforced.
Go deeper
In one line: After the Supreme Court's July 2026 ruling, the Environment Ministry has resumed appraising pending post facto clearance proposals, but will accept no new ones.
Why it matters for UPSC
Environmental clearance and EIA are core GS3 topics, asked in Mains in 2014, 2020 and 2024. The story also shows judicial review of executive instruments such as notifications and office memoranda.
The core idea
The Environmental Impact Assessment Notification, 2006 requires approval before work begins. A Post facto environmental clearance gives approval afterwards. In Vanashakti v Union of India, the Supreme Court upheld the 2017 one-time window but quashed the 2021 memorandum. The debate is ultimately about the Precautionary principle.
Numbers and dates to remember
- EIA Notification: 2006, under the Environment (Protection) Act, 1986
- 2017 notification: one-time, six-month window
- May 2025: Supreme Court struck down the whole mechanism, later recalled
- 29 July 2026: final ruling upholding the 2017 notification and quashing the 2021 memorandum
- Now processed: only pending, rejected or returned proposals
Where to go next
- Environmental Impact Assessment Notification, 2006: the rulebook for clearances
- Post facto environmental clearance: what it is and why it is contested
- Vanashakti v Union of India: the case that settled the dispute
- Precautionary principle: the idea that EIA is built on
Go deeper: Is a one-time amnesty ever justified?
For a limited window. Many projects were built in violation over the years. Demolishing them would waste resources and may cause fresh damage. A one-time window with penalties and remedial plans, like the 2017 notification, brings them under regulation instead of leaving them in legal limbo. The Supreme Court's final ruling in Vanashakti v Union of India accepted this logic for the 2017 window.
Against. The point of the Environmental Impact Assessment Notification, 2006 is to assess harm before it happens; a public hearing after construction cannot change much. Each amnesty signals that future violations may also be forgiven. In Alembic Pharmaceuticals v Rohit Prajapati (2020), the Supreme Court said ex post facto clearance derogates from the fundamental principles of environmental law and is contrary to the Precautionary principle.
What the 2026 ruling does. It separates the 2017 notification, which was a one-time, six-month window, from the 2021 memorandum. The first survives; the second does not, though applications already pending may still be processed. The Court also said that prior clearance stays mandatory unless the rules are formally amended, so the executive cannot open new windows by instruction alone.
What to watch. The Ministry says no new Post facto environmental clearance proposals will be accepted. The test is whether the pending cases are appraised with real penalties and restoration, or simply regularised.
Environmental Impact Assessment Notification, 2006
The rulebook that requires clearance before work begins
In one line: The EIA Notification, 2006 lists projects that need environmental clearance before work begins and sets out how they are assessed.
Legal base
It was issued by the Centre under the Environment (Protection) Act, 1986. An earlier EIA notification of 1994 had also made clearance mandatory; in Alembic Pharmaceuticals (2020) the Supreme Court set aside a 2002 circular that had allowed ex post facto clearance under it.
How it works
- Expert appraisal committees of the Union Environment Ministry and of the States examine proposals; State Environment Impact Assessment Authorities grant clearances at the State level.
- Stages: screening, scoping, public consultation and appraisal.
Why it is in the news
The dispute over clearing projects that skipped this process has just been settled by the Supreme Court.
Where to go next
Post facto environmental clearance
What it means to approve a project after it has started
In one line: A post facto environmental clearance is an approval granted to a project that began, expanded or modernised without the prior clearance the law requires.
How it arose
In 2017 the Environment Ministry issued a notification giving projects already in violation a one-time, six-month window to apply for clearance. In 2021 the Ministry issued an Office Memorandum on the post facto mechanism, which the Supreme Court has now quashed.
Why it is contested
Supporters argue it brings violators under regulation. Critics argue it rewards breaking the law and makes the public hearing meaningless once construction is done.
Where it stands
After the Supreme Court's July 2026 ruling, only pending, rejected or returned proposals are being processed; no new ones will be accepted.
Where to go next
Vanashakti v Union of India
The case that settled the fate of post facto clearances
In one line: Vanashakti v Union of India is the Supreme Court case on whether the Centre could allow projects to obtain environmental clearance after the fact.
The stages
- May 2025: the Court struck down the entire post facto mechanism.
- Review: the Court later recalled that judgment after a review petition, including one by the Confederation of Real Estate Developers' Association of India (CREDAI).
- 29 July 2026: final ruling. The 2017 notification was upheld; the 2021 Office Memorandum was quashed; pending applications may be processed; prior clearance remains mandatory unless the rules are formally amended.
Why it matters
It shows a court checking an executive instrument (an office memorandum) against the statutory scheme, while accepting a time-bound window.
Where to go next
Precautionary principle
The idea that harm should be prevented, not repaired
In one line: The precautionary principle says that where an activity may cause serious harm and scientific knowledge is incomplete, caution and review should come before the activity, not after.
In Indian law
In Alembic Pharmaceuticals v Rohit Prajapati (2020), the Supreme Court held that ex post facto environmental clearances are contrary to the precautionary principle and to sustainable development, and it set aside a 2002 circular that had allowed them. It treated public hearing, screening, scoping and appraisal as essential parts of decision-making.
Link to clearance
Prior environmental clearance is the precautionary principle in practice: the impact is studied, and the public heard, before work starts. Post facto clearance reverses that order, which is why courts have viewed it with suspicion.

1. It upheld the 2017 notification on violation cases.
2. It quashed the 2021 Office Memorandum on violation cases.
3. It barred the processing of all pending post facto applications.
How many of the statements given above are correct?- Only one
- Only two
- All three
- None
Show answer
Answer: (b) Only two. Statements 1 and 2 are correct. Statement 3 is wrong: the Court allowed pending applications to be processed, which is why the Ministry has resumed appraisal.
Consider the following statements:
Statement-I: The Environment Ministry will now process only post facto proposals that were pending, rejected or returned.
Statement-II: The Supreme Court held that prior environmental clearance remains mandatory unless the rules are formally amended.
Which one of the following is correct in respect of the above statements?- Both Statement-I and Statement-II are correct and Statement-II explains Statement-I
- Both Statement-I and Statement-II are correct and Statement-II does not explain Statement-I
- Statement-I is correct but Statement-II is incorrect
- Statement-I is incorrect but Statement-II is correct
Show answer
Answer: (a) Both Statement-I and Statement-II are correct and Statement-II explains Statement-I. Both are correct. Because prior clearance remains the rule and the Court only allowed pending applications to proceed, the Ministry is not accepting new post facto proposals; Statement-II explains Statement-I.
Consider the following:
1. Screening
2. Scoping
3. Public consultation
4. Appraisal
How many of the above are stages of the environmental clearance process under the EIA Notification, 2006?- Only one
- Only two
- Only three
- All four
Show answer
Answer: (d) All four. All four are stages. Screening is the first check of a proposal; scoping fixes the terms of reference; public consultation includes a hearing; appraisal is by an expert committee. The Supreme Court listed public hearing, screening, scoping and appraisal as parts of the decision-making process in Alembic Pharmaceuticals (2020).
