The Supreme Court of India addressed a significant dispute regarding the distribution of legislative powers between the Union and the States, specifically concerning the taxation of mineral rights. The case focused on whether royalty on minerals, as outlined under the Mines and Minerals (Development and Regulation) Act (MMDR Act), should be considered a tax and whether State legislatures can impose taxes on mineral-bearing lands by using the value of minerals as a tax base. The Court examined the inter-relationship between various constitutional entries related to mines and minerals and provided clarity on the limitations imposed on State taxation powers.
