Supreme Court Quashes 2021 Office Memorandum on Retrospective Environmental Clearance

What happened
01

The Supreme Court quashed the 2021 Office Memorandum (OM) that had permitted the Centre and other authorities to grant ex post facto (retrospective) environmental clearances to projects and undertakings that had commenced operations without prior clearance

02

The Bench held that such a mechanism cannot be created through an executive OM and must instead flow from a valid statutory notification

03

The Court simultaneously upheld the Centre's power to frame a time-bound "amnesty scheme" for regularising past violations, provided it is issued as a formal notification under the governing environmental law rather than an internal administrative memo

04

Clearances already granted under the 2017 notification (which had provided a one-time amnesty window) and under the now-quashed 2021 OM will continue to remain valid unless individually challenged before a competent forum

Ex Post Facto Environmental Clearance and the Precautionary Principle

Environmental Clearance (EC) is a mandatory prior approval required before a listed project can start construction or operation, under the Environment (Protection) Act, 1986. "Ex post facto" or retrospective clearance refers to granting this approval after a project has already begun operating without it — a practice the Supreme Court has repeatedly held to be contrary to environmental jurisprudence, since it defeats the very purpose of prior impact assessment.

Key Details

  • In Alembic Pharmaceuticals Ltd. v. Rohit Prajapati (2020), the Supreme Court held that the concept of an ex post facto EC is "in derogation of the fundamental principles of environmental jurisprudence" and is an "anathema" to the EIA process, being contrary to both the precautionary principle and the goal of sustainable development
  • The precautionary principle (recognised in Indian environmental law since Vellore Citizens' Welfare Forum v. Union of India, 1996) requires anticipatory environmental action rather than remedial regularisation after harm has occurred
  • The 2021 OM had sought to create a fresh window for such retrospective regularisation after the 2017 notification's one-time scheme lapsed
Connection to this news

The present ruling reaffirms the Alembic line of reasoning — the Court will not allow retrospective clearance to become a routine administrative practice, and any exception must be tightly bound by statute, not issued as a discretionary executive circular.

Environment (Protection) Act, 1986: Section 3 and the EIA Notification, 2006

The Environment (Protection) Act, 1986 is the umbrella legislation enacted after the Bhopal Gas Tragedy (1984) that empowers the Central Government to take all measures necessary to protect and improve the environment. Section 3 authorises the Central Government to issue rules and notifications, including constituting authorities and imposing restrictions on the location and operation of industries.

Connection to this news

The Court's core objection to the 2021 OM was procedural — an internal memo cannot substitute for a notification under Section 3, since a notification carries statutory backing and is subject to greater accountability than an executive circular.

Article 14 and Article 21: Constitutional Basis for Environmental Regulation

Article 21 (Right to Life) has been judicially expanded to include the right to a clean and healthy environment, while Article 14 (Right to Equality) requires that executive action be non-arbitrary, reasonable, and proportionate. Both provisions anchor judicial review of environmental executive instruments such as the 2021 OM.

Connection to this news

By testing the 2021 OM against Articles 14 and 21, the Court signalled that environmental clearance procedures are not merely administrative matters but engage constitutional rights, raising the bar for any future regularisation scheme.
