In Vanashakti v Union of India, 2026 INSC 761 a three-judge bench of the Supreme Court pursuant to review proceedings settled the long-contested issue of ex post facto Environmental Clearance (EC) granted under the Environment Impact Assessment Notification, 2006 (EIA Notification, 2006). The Court held that the prior EC regime is mandatory in nature and upheld the validity of the 2017 Notification issued by the Ministry of Environment, Forest and Climate Change (MoEFCC) as a time bound amnesty scheme, and struck down the 2021 Office Memorandum (2021 OM) as an impermissible administrative action with prospective effect. The Court passed a common judgment and order in a group of petitions.
