State Of Rajasthan & Ors vs Hindustan Zinc Ltd. & Anr

The Supreme Court addressed appeals from the State of Rajasthan and Hindustan Zinc Limited regarding the calculation of royalty under the Mines and Minerals (Development and Regulation) Act, 1957. The Court held that the High Court's quashing of additional royalty demands was erroneous, as the State is entitled to recover royalty under Section 9 of the Act and relevant Mineral Concession Rules. The Court set aside the High Court's judgment, thereby allowing the State's appeal and reinstating the validity of the notices for additional royalty demands.
