M/S. Nagarjuna Construction Co. Ltd vs Govt. Of A.P. & Ors

The Supreme Court addressed the legality of the demand for seigniorage fees under the Andhra Pradesh Minor Mineral Concession Rules, 1966, specifically Rule 35-A. The Court held that the State Government's exercise of suo motu revisional jurisdiction was valid, confirming the original demand for seigniorage fees while rejecting the appellants' claims of contradictory notices. The Court emphasized that the contractors are responsible for ensuring compliance with mining regulations and that the demand for fees was justified based on the materials supplied for construction work.
