Notes

  • The Supreme Court quashed the 2021 Office Memorandum (OM) that allowed ex post facto environmental clearances for infrastructure projects.
  • The Court held that administrative instructions cannot override or supplant delegated legislation, specifically the 2006 Environmental Clearance (EC) notification.
  • The 2021 OM was deemed to create a permanent, parallel regime that circumvented the mandatory prior EC process.
  • The Court ruled that amnesty measures must be rare, finite in duration, and limited to specific classes of projects, rather than a perpetual policy.
  • The judgment was delivered with prospective effect to prevent disruption to ongoing public interest projects like hospitals and airports.
  • The Court criticized the 'pollute and then pay' principle, emphasizing that environmental governance must align with sustainable development.
  • The judiciary retains the power to grant ex post facto clearances under Article 142 of the Constitution in exceptional cases.
  • Retrospective clearances granted under the 2017 one-time amnesty notification remain valid unless challenged individually.
