M/S PRP EXPORT & ETC. vs CHIEF SEC. GOVT. OF TAMIL NADU .

The Supreme Court upheld the High Court's decision allowing the petitioner, a registered partnership firm engaged in granite quarrying, to continue operations under the existing lease while emphasizing the need for due process under The Mines & Minerals (Development & Regulation) Act, 1957. The Court noted that the sealing of the petitioner's factory and equipment was unjustified without a show cause notice regarding license cancellation. The ruling established that while the state can take action against illegal mining, it must adhere to legal procedures.
