The case originated from Writ Petitions and a Civil Appeal challenging the legality of certain government notifications and office memoranda (OMs) concerning Environmental Clearances (ECs).
Specifically, the petitions challenged the Environment Impact Assessment (EIA) Notification, 2017, and the Office Memorandum (OM) dated 7th July 2021 (‘the 2021 OM’). These measures aimed to provide a mechanism for projects that had already commenced work or expanded without obtaining the mandatory prior EC
The 2017 notification allowed projects in violation of the EIA notification to apply for ex post facto EC within a six-month window. The Union of India had previously stated that this 2017 notification was a “one-time measure”.
The 2021 OM introduced a Standard Operating Procedure (SOP) for granting ex post facto EC in cases of violation, with provisions for penalty and environmental restoration.◦The High Court of Madras, in a judgment dated 30th August 2024, had already quashed the 2021 OM and the 2017 notification, a decision which was also under challenge in a Civil Appeal before the Supreme Court.
Law Involved
Article 51A(g) of the Constitution of India: Emphasises the fundamental duty of every citizen to protect and improve the natural environment.
Article 21 of the Constitution of India: Interpreted to include the right to live in a pollution-free atmosphere as a fundamental right.
The Environment (Protection) Act, 1986 (‘the 1986 Act’): Grants the Central Government extensive powers to take measures for protecting and improving the quality of the environment and abating environmental pollution. Section 15 of this Act provides for penalties for violations.
Environment Impact Assessment (EIA) Notification, 2006: Requires prior environmental clearance for certain projects and activities.
Principles of Environmental Jurisprudence: The judgment extensively discusses the concept of “ex post facto” environmental clearance., the Precautionary Principle2127, and the Polluter Pays Principle.
Judicial Precedents: The Court relied on its previous judgments in Common Cause v. Union of India and Alembic Pharmaceuticals v. Rohit Prajapati, which critically viewed ex post facto EC as detrimental to the environment and alien to environmental jurisprudence.
Reasoning
The Supreme Court found “ex post facto” environmental clearance to be “completely alien to environmental jurisprudence”. It reiterated that EC is a precautionary principle and must be obtained before commencing any project.
The Court strongly criticised the 2017 notification and the 2021 OM for attempting to regularise illegal activities. The 2021 OM was seen as encouraging entities to operate without prior EC, knowing they could later seek “one-time relaxation”.
The Court highlighted that the 2021 OM undermined the Polluter Pays Principle, as it allowed regularisation upon payment of compensation rather than mandating closure or demolition for serious violations.
It was emphasized that the right to a pollution-free environment (Article 21) and the fundamental duty to protect the environment (Article 51A(g)) are paramount, and measures like the 2021 OM violate these constitutional mandates.
The Court explicitly agreed with the Madras High Court’s decision to quash the 2021 OM and the 2017 notification, stating that these measures were arbitrary and illegal… The Court further noted that the 2021 OM essentially allowed for EC to be granted with retrospective effect, which “regularises illegality committed earlier”.
Holding
The Supreme Court allowed the writ petitions and civil appeals, finding in favour of the petitioners.
It explicitly held that the EIA Notification, 2017, and the Office Memorandum dated 7th July 2021 are illegal [36(a)].
The Central Government is restrained from issuing similar circulars, orders, or notifications that grant ex post facto EC or provide “one-time relaxation” for violations of the EIA notification [36(b)].
However, the Court clarified that Environmental Clearances already granted under the 2017 notification and 2021 OM shall remain unaffected [36(c)].
