The middle path | Explaining Supreme Court’s latest verdict on post facto environmental clearances

The Supreme Court's landmark judgment quashing the Centre's 2021 Office Memorandum (OM) on ex post facto environmental clearance marks a watershed moment in India's environmental jurisprudence. To understand its significance, we must first trace the background: the Environment Impact Assessment (EIA) Notification, 2006, issued under Section 3 of the Environment (Protection) Act, 1986, mandates prior environmental clearance (EC) for specified projects. However, over the years, numerous projects commenced operations without obtaining EC, creating a regulatory grey zone. In response, the Ministry of Environment, Forest and Climate Change (MoEFCC) issued an OM in 2017, and subsequently a more expansive one on June 18, 2021, allowing post facto clearance for such violations — essentially an amnesty scheme enabling project proponents to regularize illegalities by paying penalties and fulfilling conditions. The 2021 OM was challenged before the Supreme Court by environmental activists and NGOs, arguing it bypassed the statutory framework. The Court, in its verdict delivered in April 2024 (Civil Appeal No. 2784 of 2024), struck down the OM, holding that the power to grant ex post facto clearance cannot be exercised through an administrative instruction but only through a statutory notification issued under the Environment (Protection) Act, 1986, after following due process including public consultation. Crucially, the Court ruled that any such amnesty must be confined to projects of "supervening public interest" — a narrow exception for projects where halting operations would cause disproportionate harm to public welfare, such as critical infrastructure or strategic projects. Key stakeholders include the Union Executive (MoEFCC), which sought to regularize violations administratively; the Judiciary, which upheld constitutional limits on executive power; project proponents (industries, developers) who benefited from the amnesty; and civil society/environmental groups who argued it incentivized non-compliance. The judgment reinforces the doctrine of separation of powers under Articles 53, 73, and 162 of the Constitution — the executive cannot create substantive rights or amnesty schemes without legislative sanction. It also invokes the precautionary principle and polluter pays principle, embedded in Article 21 (right to life including clean environment) and Article 48A (directive to protect environment). The significance for India is profound. Economically, it introduces regulatory certainty — industries can no longer assume violations will be routinely condoned. Politically, it checks executive overreach and mandates parliamentary scrutiny for environmental amnesties. Socially, it empowers communities affected by illegal projects, as statutory notifications require public hearings. Internationally, it aligns India with its commitments under the Rio Declaration (1992) and the Paris Agreement, reinforcing credible environmental governance. Looking ahead, the MoEFCC may issue a fresh statutory notification for ex post facto clearance, but only after public consultation and legislative vetting. The judgment also puts pressure on State Pollution Control Boards and the National Green Tribunal to enforce compliance strictly. For aspirants, this case is a masterclass in administrative law, environmental federalism, and the evolving role of the judiciary in safeguarding ecological democracy.
