The Supreme Court has recently flagged regulatory uncertainty surrounding the grant of post-facto environmental clearances (ECs), following the recall of its earlier judgment that had barred retrospective approvals for projects commenced without prior environmental clearance. The Court’s observations have revived debate on the legality of ex-post facto regularisation under India’s environmental regulatory framework.
Case Background
The controversy originates from challenges to executive mechanisms permitting environmental clearance to be granted after project commencement — commonly referred to as post-facto or retrospective environmental clearances.
In 2017, the Union Ministry of Environment, Forest and Climate Change introduced a “violation window” allowing projects that had begun operations without prior EC to seek regularisation upon payment of penalties and submission of remediation plans. A subsequent Office Memorandum issued in 2021 operationalised a detailed appraisal process for such violations.
These executive instruments were challenged before the Supreme Court on the ground that they diluted the preventive architecture of environmental regulation.
Earlier Supreme Court Judgment Barring Retrospective EC
A two-judge bench of the Supreme Court, in May 2025, struck down the post-facto clearance regime.
The Court held that environmental clearance is inherently preventive and must precede project execution. Granting approvals retrospectively, it ruled, would legitimise environmental violations and undermine the statutory mandate under the Environment (Protection) Act, 1986 and the EIA Notification framework.
The judgment quashed both the 2017 notification and the 2021 Office Memorandum, effectively prohibiting the grant of retrospective environmental clearances.
Recall of the Judgment
Subsequently, a three-judge bench, by a 2:1 majority, recalled the May 2025 ruling.
The majority held that the earlier bench had not adequately considered binding precedents where post-facto clearances were examined in limited contexts. It further noted that striking down the regime could have far-reaching consequences for large infrastructure and industrial projects already operational across the country.
The Court also expressed concern that invalidating retrospective approvals could expose numerous public utility projects to closure or demolition, triggering economic and administrative disruption.
Dissenting View
In dissent, one judge strongly opposed the recall, holding that post-facto environmental clearance has no legal foundation within India’s environmental jurisprudence.
The dissent emphasised that allowing retrospective approvals would erode the precautionary principle and incentivise project proponents to commence operations without prior regulatory scrutiny.
Present Legal Position
Following the recall, the legal position on post-facto environmental clearances remains unsettled.
The earlier prohibition no longer operates as binding precedent, and the issue is expected to undergo fresh judicial examination. In the interim, regulatory authorities may continue processing violation cases under existing executive frameworks, subject to final adjudication.
Supreme Court’s Recent Observations
In subsequent proceedings, the Supreme Court has noted that conflicting judicial signals on retrospective environmental approvals have generated regulatory uncertainty.
The Court indicated that clarity is required on the permissible scope of executive power to regularise environmental violations and the extent to which such mechanisms align with statutory and constitutional environmental protections.
Legal Issues Involved
The litigation raises foundational questions in environmental law, including:
- Whether environmental clearance can legally be granted after project commencement
- Scope of executive regularisation powers under the Environment (Protection) Act
- Applicability of the precautionary principle
- Balancing environmental compliance with infrastructure continuity
- Consequences of illegal project commencement
Institutional Significance
The outcome of this litigation is expected to have sector-wide implications across infrastructure, mining, manufacturing, and energy projects.
A final ruling will determine whether India’s environmental clearance regime remains strictly preventive or accommodates post-violation regulatory regularisation under controlled conditions.
Current Status
The matter remains pending consideration before the Supreme Court, with the legality and limits of post-facto environmental clearances yet to be conclusively settled.
