Ex Post Facto Environmental Clearances

Ex Post Facto Environmental Clearances is a debated environmental regulation. The Supreme Court’s Recall has raised questions yet again about the future of India’s environmental governance. Read here to learn more.

In a landmark yet deeply debated move, the Supreme Court of India has recalled its May 16, 2025, Vanashakti judgment, which had categorically banned the granting of ex post facto (retrospective) environmental clearances (ECs).

The recall has reopened longstanding tensions at the heart of India’s environmental regulation: the conflict between sustainable development and environmental rule of law.

The judgment now stands as a pivotal moment in India’s environmental jurisprudence. It raises important questions about the limits of judicial oversight, the extent of executive discretion, and the delicate balance between ecological protection and economic imperatives.

The Vanashakti Judgment

In May 2025, a two-judge Bench delivered a ruling that reverberated across industries and environmental governance frameworks.

The decision held that ex post facto environmental clearances are fundamentally incompatible with India’s environmental constitutionalism.

Key findings of the 2025 ruling:

• Granting retrospective environmental clearances violated the precautionary principle, which mandates that potential environmental harm must be prevented at the outset, not mitigated after damage has occurred.
• The Bench struck down a 2017 notification and 2021 office memoranda issued by the Ministry of Environment, Forest and Climate Change (MoEFCC), which had institutionalised post-facto clearances.
• The Court called the Centre’s approach “crafty drafting” that legitimised illegal construction and expansion undertaken without prior approval.
• The verdict barred the government from issuing any future notifications or circulars allowing retrospective regularisation.

More than a legal rebuke, the Vanashakti judgment signalled a moral stance. It brought the Court squarely on the side of preventive environmental governance, an approach vital to safeguarding ecological security in a rapidly developing country.

What is Ex Post Facto Environmental Clearance?

Under the Environmental Impact Assessment (EIA) 2006 Rules, prior environmental clearance is mandatory for a wide range of industrial, mining, infrastructure, and power projects.

• Yet, in practice, many projects begin construction or operations without approval, either due to procedural delays or deliberate violations.
• Ex post facto clearances are approvals granted after a project has already begun operations, often years after the damage has occurred.

Significance

They serve to:

• convert illegal activity into a quasi-legal one,
• impose penalties or compensatory charges,
• allow continuation of projects that might otherwise face closure or demolition.

Industries argue that such a mechanism is necessary to avoid catastrophic financial losses.

Environmentalists argue that it rewards illegality and undermines the preventive architecture of environmental law.

The Recall of the Ban: The Court’s Majority View

The latest ruling marks a significant shift in judicial approach.

The Supreme Court’s majority held that an absolute ban on retrospective environmental clearances could have devastating consequences, including:

• halting ongoing public projects,
• financial losses running into thousands of crores,
• wastage of taxpayer money,
• operational paralysis in critical sectors.

The majority reasoned that India’s developmental needs, particularly in infrastructure and energy, require flexibility. While not endorsing post-facto clearances outright, the Court stated they could be allowed “in exceptional circumstances” with:

• stringent scrutiny,
• heavy penalties,
• ecological restoration mandates.

The Bench also observed that the issue involves complex constitutional and environmental questions, best suited for reconsideration by a larger Bench.

This indicates a recognition of the jurisprudential tension between environmental protection and economic pragmatism.

The Judicial Dissent

• Ex-post facto environmental clearances are “an anathema, a curse devoted to evil,” as they incentivise illegal conduct.
• They erode the credibility of environmental regulation by normalising violations.
• In a country facing acute pollution, evident from Delhi’s toxic smog, regulators cannot afford to weaken the precautionary principle.
• Environmental protections under Article 21 demand stricter, not looser, enforcement mechanisms.
• Regularisation after damage is inconsistent with the irreversible nature of ecological harm.

This judicial dissent, reminiscent of earlier environmental dissents, underscores a growing fear: that industrial compliance is becoming negotiable under the guise of national development.

Why Ex Post Facto Environmental Clearances Were Problematic

The earlier ban had strong justification rooted in environmental and administrative law:

1. Violation of the Precautionary Principle: Environmental decision-making must be proactive, not reactive. Retrospective approvals inherently fail this test.
2. Encouragement of Illegal Activity: Developers may intentionally bypass procedures, knowing regularisation is possible upon payment of penalties.
3. Weakening of the EIA Framework: Prior environmental clearance is not just a formality; it involves public hearings, environmental appraisal, social impact assessment, and mitigation planning.
4. Irreversibility of Ecological Damage: Mining, industrial effluents, deforestation, and air pollution inflict harm that cannot always be undone.
5. Threat to Public Health: Unregulated phases of projects often coincide with the most polluting activities.
6. Erosion of Rule of Law: Allowing violators to be rewarded damages public faith in environmental justice.

• The recall does not negate these concerns; it merely argues that exceptional situations may justify relaxation.

Development vs. Environmental Justice

India’s environmental regulatory architecture has long been shaped by a struggle between two imperatives:

• Accelerating economic growth, and
• Protecting ecological security and public health.

The recall indicates the judiciary’s attempt to strike a pragmatic balance. Yet, the risk is clear: flexibility can slip into permissiveness.

This is especially concerning given India’s challenges:

• high pollution levels in major cities,
• fragile coastal ecosystems,
• rapid industrialisation,
• climate-induced vulnerabilities.

Against this backdrop, retrospective clearances may undermine decades of progress in environmental governance.

Way Forward

To prevent misuse of retrospective ECs, India’s regulatory system must incorporate robust safeguards:

1. Strict Penalty & Restoration Regime: Any project receiving ex post facto clearance must:

• pay punitive fines,
• undertake ecological restoration,
• deposit environmental bonds,
• initiate community compensation where necessary.

2. Strengthening Monitoring and Enforcement

• satellite imagery,
• real-time emissions tracking,
• AI-based compliance monitoring
  to detect illegal project starts.

3. Transparency and Public Access: Publish all violations, penalties, and corrective actions to empower local communities and watchdog groups.
4. Streamlining Prior environmental clearance Procedures: Quicker, more efficient environmental appraisal reduces industry’s incentive to bypass the law.
5. Larger Bench Clarification: A constitutionally consistent, development-sensitive doctrine on retrospective clearances must emerge from a larger Bench to prevent ambiguity.

Conclusion

The Supreme Court’s recall of the Vanashakti judgment is not merely a legal development; it is a reflection of India’s developmental tensions.

While the Court’s attempt to avoid economic disruption is understandable, it must not weaken the preventive architecture that has long defined India’s environmental jurisprudence.

Retrospective clearances, if allowed, must remain rare, penal, transparent, and deterrent. The ultimate goal must remain uncompromised: ensuring India’s development does not come at the cost of irreversible ecological loss and the fundamental right to a clean and healthy environment.

If implemented carefully, India can achieve a system that protects both its developmental aspirations and its environmental future.
