Mineral Area Development Authority & Anr. vs M/S Steel Authority of India & Anr. Etc.
Background
This decades-old batch of appeals (the lead case dating back to 1999, joined by dozens of connected appeals) concerned whether State legislatures have the constitutional power to levy taxes on mineral rights and mineral-bearing land, or whether that power belongs exclusively to Parliament through the Mines and Minerals (Development and Regulation) Act, 1957 (MMDR Act). A seven-judge bench in India Cement Ltd. v. State of Tamil Nadu (1989) had held that "royalty" paid by mining lease holders is itself a tax, so States could not separately tax mineral rights since the field was already occupied by Parliament's MMDR Act; a later Constitution Bench in Kesoram Industries (2004) suggested this was based on a clerical/typographical error and that royalty was not a tax. The conflict was referred to a nine-judge bench to settle the law definitively.
Decision Breakdown
The majority held that royalty paid under a mining lease is a contractual consideration for the right to extract minerals, not a tax, correcting the position in India Cement. It held that Entry 50 of List II (List II being the State List) empowers State legislatures to tax mineral rights, subject only to any limitations Parliament specifically imposes through a law "relating to mineral development", and the MMDR Act, as it currently stands, does not itself impose such a limitation on the States' taxing power. Separately, the majority held that States can also tax mineral-bearing land under Entry 49 of List II (taxes on lands and buildings), using the quantity or value of minerals extracted as a yardstick for that tax, since Entries 49 and 50 operate in different fields. Several earlier decisions that had constrained State taxing power in this area were overruled. Justice Nagarathna dissented, holding that royalty is in the nature of a tax and that allowing States to independently tax mineral rights and mineral-bearing land using mineral value as a measure would disturb the constitutional and economic balance intended by Parliament's uniform national regulation of mineral development.
Lesson Learnt
In India's federal structure, states retain meaningful taxing powers over natural resources located within them unless Parliament has clearly and specifically restricted that power by law: a broad national regulatory statute does not automatically strip states of their constitutionally assigned taxation entries.
