Supreme Court Quashes Retrospective Environmental Clearances — [Environment & Ecology: GS Paper III]

1. The Core News Report

The Supreme Court of India has quashed the Union Environment Ministry’s 2021 Office Memorandum (OM) that granted the Central and State government authorities the power to issue ex-post-facto environmental clearances. The bench ruled that retrospective clearances derogate from the core principles of environmental jurisprudence and the Environment (Protection) Act, 1986.

The Supreme Court emphasized that permitting ex-post-facto clearances allows project proponents to operate illegally without prior Environmental Impact Assessment, leading to irreversible ecological damage. However, the apex court clarified that in exceptional circumstances and strictly in the larger public interest, the Centre may introduce a limited, time-bound amnesty scheme through a valid statutory notification.
