Supreme Court quashes 2021 OM allowing ex post facto environmental clearance, but upholds Centre’s power to provide ‘amnesty schemes’

This judgment highlights the critical constitutional principle regarding the hierarchy of laws and the limits of executive action. The Court asserted that an administrative order (the 2021 OM) cannot supplant or substantially alter a delegated legislation (the Environment Impact Assessment Notification, 2006). Delegated legislation derives its authority directly from a parent Act (the Environment (Protection) Act, 1986), giving it a higher legal standing than mere executive instructions. Furthermore, the Court struck down the OM for violating Article 14 (Right to Equality) and Article 21 (Right to Life) of the Constitution of India. It argued that the OM created a 'perpetual amnesty scheme' without an intelligible differentia (a clear, rational basis for classification) for selecting projects, thus failing the test of reasonableness and proportionality. However, the Court recognized its own plenary powers under Article 142 to grant ex post facto clearances in exceptional circumstances to do complete justice, highlighting the unique discretionary authority vested in the Apex Court.

The ruling strongly reinforces core environmental jurisprudence, specifically the precautionary principle and sustainable development. The Environment Impact Assessment Notification, 2006 makes prior environmental clearance mandatory for large-scale projects to assess and mitigate potential ecological damage before it occurs. Allowing a blanket ex post facto clearance regime contradicts the precautionary principle, as it allows potentially harmful activities to commence without assessment. The Court emphasized that the objectives of the Environment (Protection) Act, 1986 require a balanced approach where economic development does not come at the cost of irreversible environmental degradation. While acknowledging the economic reality of ongoing projects by applying the ruling prospectively, the judgment clearly sets a precedent that retroactive environmental compliance cannot be institutionalized as a standard procedure, thereby strengthening the regulatory framework against environmental violations.

The judgment navigates the complex tension between strict regulatory compliance and the practical implications of large-scale infrastructure development. The Court acknowledged the government's argument regarding the 'devastating effect' of halting ongoing public projects worth thousands of crores, demonstrating an understanding of economic and developmental imperatives. By allowing past clearances under the 2017 notification (a 'one-time amnesty') and applying the quashing of the 2021 OM prospectively, the Court applied the doctrine of prospective overruling, balancing the rule of law with practical realities. Crucially, the Court did not entirely bar the government from regularizing unauthorized projects; instead, it clarified the correct mechanism. It stated that such regularization must be through a specific 'amnesty' notification under the delegated legislation, targeted at select projects where continuation serves a 'supervening public interest,' rather than an open-ended administrative order. This demands a higher standard of justification and transparency from the executive when bypassing standard environmental safeguards.
