Goa Foundation vs Union Of India & Ors

The Supreme Court upheld the validity of the Goa, Daman and Diu Mining Concessions (Abolition and Declaration as Mining Leases) Act, 1987, which abolished mining concessions granted prior to Goa's liberation and deemed them as mining leases under the Mines and Minerals (Development & Regulation) Act, 1957. The Court clarified that the provisions of the MMDR Act apply to these deemed leases, reinforcing the legislative intent to regulate mining activities post-liberation. The Court also addressed the interim orders allowing concessionaires to continue operations, emphasizing compliance with statutory requirements.
