Vanashakti PIL: Supreme Court Battle Over Ex Post Facto Environmental Clearances

Few environmental law disputes in recent Indian history have generated as much judicial and policy debate as the Vanashakti PIL. Filed by the Mumbai-based NGO Vanashakti, this public interest litigation challenged the legality of granting environmental clearances after a project has already commenced construction or operation, a practice known as ex post facto clearance. The case has moved through multiple Supreme Court benches, producing conflicting rulings that have left developers, regulators, and environmental advocates grappling with uncertainty. Understanding the trajectory of this litigation is essential for anyone involved in infrastructure development, environmental compliance, or regulatory policy in India.

What Is the Vanashakti PIL About

Vanashakti filed its PIL in the Supreme Court in December 2023, targeting a Standard Operating Procedure (SOP) issued by the Ministry of Environment, Forest and Climate Change (MoEFCC) on 7 July 2021. This SOP laid down the procedure for identification and handling of violation cases under the Environmental Impact Assessment (EIA) Notification 2006. The petitioner argued that this SOP effectively functioned as an amnesty scheme for projects that had commenced construction or expanded operations without obtaining the mandatory prior environmental clearance. The legal foundation of the challenge rested on the Environment Protection Act 1986, under which the EIA Notification derives its authority. Vanashakti contended that the MoEFCC had exceeded its delegated powers by creating a regularisation pathway that the parent statute did not contemplate. The PIL also challenged an earlier notification dated 14 March 2017, which had first introduced the concept of granting clearances to projects that were already operational without prior approval.

The May 2025 Ruling: Striking Down Ex Post Facto Clearances

On 16 May 2025, the Supreme Court delivered a landmark judgment in Vanashakti v. Union of India, striking down both the 14 March 2017 notification and the 7 July 2021 Office Memorandum. The Court held that granting environmental clearances retrospectively violates the constitutional right to a pollution-free environment guaranteed under Article 21 of the Constitution. The reasoning was grounded in the precautionary principle: once a project begins without clearance, the environmental damage may already be irreversible, and retroactive approval undermines the entire purpose of the EIA framework. The judgment sent shockwaves through the real estate and infrastructure sectors, as thousands of projects across India had obtained or were in the process of obtaining ex post facto clearances under the impugned SOP. Industry bodies, particularly the Confederation of Real Estate Developers of India (CREDAI), immediately sought review of this decision, arguing that a blanket prohibition would create enormous economic disruption without commensurate environmental benefit.

The November 2025 Review: A Dramatic Reversal

On 18 November 2025, a three-judge bench of the Supreme Court delivered judgment in CREDAI v. Vanashakti and Others, effectively recalling the May 2025 ruling. By a 2:1 majority, the Court held that retrospective environmental clearances could be granted, subject to certain conditions. These conditions included the payment of penalties and a demonstration that the project could be carried out sustainably in accordance with environmental norms. The majority opinion reasoned that a complete prohibition on ex post facto clearances would be disproportionate, particularly for projects where the environmental impact was manageable and could be mitigated through conditions imposed at the clearance stage. The dissenting judge, however, maintained that allowing retrospective clearances creates a perverse incentive for developers to proceed without approval, knowing that regularisation remains available. This split in judicial opinion has left the legal position in a state of flux, with the matter listed for further hearing in 2026.

Why This Case Matters for Environmental Governance

The Vanashakti litigation sits at the intersection of two competing imperatives: environmental protection and economic development. The EIA framework was designed to ensure that the environmental consequences of a project are assessed before irreversible commitments are made. When clearances are granted after the fact, the assessment becomes a formality rather than a genuine decision-making tool, because the economic and political pressure to approve an already-operational project is immense. On the other hand, demolishing or shutting down completed projects carries its own environmental and social costs. The Supreme Court's evolving jurisprudence in this case reflects the difficulty of balancing these considerations. The case also raises important questions about the scope of delegated legislation: can the executive create regularisation pathways through SOPs and office memoranda when the parent statute does not expressly authorise such mechanisms?

Practical Takeaways

The current legal position, following the November 2025 review, permits ex post facto environmental clearances subject to penalty payments and sustainability conditions, but this position remains contested and may change when the matter is next heard. Project proponents should not treat the review judgment as a green light to bypass prior clearance requirements, as the dissenting opinion and the possibility of further judicial review create significant legal risk. Developers with ongoing projects that lack prior clearance should document their environmental mitigation efforts comprehensively, as this evidence will be critical in any future clearance application. Environmental compliance officers should monitor the case closely, as any referral to a larger bench could fundamentally alter the legal landscape. For regulators, the case underscores the need for a clear statutory framework governing violation cases, rather than relying on executive SOPs that are vulnerable to legal challenge. The Vanashakti PIL remains one of the most consequential environmental law cases in recent Indian judicial history, and its final resolution will shape environmental governance for years to come.
