Mineral Royalty Is Payable at the Rate on Date of Dispatch: Supreme Court in BMM Ispat

The Supreme Court has clarified an important question for the mining sector: when the royalty rate on a mineral is increased by the Central Government, which rate applies to minerals that were won earlier but dispatched later. In Director of Mines and Geology v. BMM Ispat Ltd (2026 INSC 627), decided on 4 June 2026, the Court held that royalty under the Mines and Minerals (Development and Regulation) Act, 1957 must be paid at the rate in force on the date the minerals are actually removed or dispatched from the mine, regardless of any contrary understanding in the parties' contract.

The ruling reinforces a basic principle of public revenue law, namely that a statutory levy cannot be frozen by private agreement. It is relevant not only to mining lessees and State governments but to anyone interested in how courts treat the interaction between statute and contract.

Background of the Dispute

The dispute arose from an auction. BMM Ispat had emerged as a successful bidder in 2014, at a time when royalty on iron ore stood at one rate. Before the entire quantity could be removed from the stockyard, the Central Government amended the Second Schedule to the MMDR Act with effect from 1 September 2014, increasing the royalty on iron ore. The question was whether the lessee had to pay the increased rate on the minerals that were dispatched after the amendment.

The lessee argued that the rate contemplated at the time of the auction should govern the entire quantity, on the basis that the commercial bargain had been struck on that footing. The State authorities contended that royalty is a statutory charge tied to the removal of the mineral, and that the rate in force on the date of dispatch must apply, irrespective of when the auction took place.

What the Supreme Court Held

The Court sided with the statutory position. It held that royalty is a statutory impost linked to the removal or dispatch of minerals, and that it must be paid at the rate for the time being specified in the Second Schedule as on the date the mineral is moved. A prior contractual term or understanding between the parties cannot freeze or limit the effect of a later statutory increase.

The bench of Justices Sanjay Karol and N. Kotiswar Singh thus confirmed that the relevant moment for fixing the rate is the date of dispatch, not the date of the auction or the date of the agreement. Minerals removed after the amendment attract the revised rate.

The Principle: Statute Overrides Contract

The decision rests on a settled idea in public law. Where a levy is created and fixed by statute, parties cannot contract out of it. If the legislature or the executive, acting under statutory authority, revises the rate, the revised rate applies to transactions that occur after the change, unless the amendment itself says otherwise.

This protects public revenue from being defeated by private arrangements and ensures uniformity, so that two lessees dispatching the same mineral on the same date pay the same rate. The same logic appears in other areas where courts refuse to let agreements override mandatory legal requirements, whether the levy is a tax, a duty or a statutory royalty. The character of the charge, rather than the label the parties give it, decides how it is treated.

Implications for Mining Lessees and States

For mining lessees, the practical lesson is that royalty liability is dynamic and follows the schedule in force at dispatch. Stockpiling minerals does not lock in an older, lower rate, and financial planning for mining operations should account for the possibility of statutory revisions before dispatch is complete.

For State governments, the ruling supports timely collection of revenue at current rates and reduces litigation over which rate applies to delayed dispatches. The judgment fits within a broader set of recent decisions on regulatory and statutory questions, including the Supreme Court order setting up an expert committee to define the Aravalli hills and ranges and the ruling on arbitration limitation under Section 34(3).

Key Takeaways

Royalty under the MMDR Act, 1957 is payable at the rate in force on the date the mineral is removed or dispatched. A contract cannot freeze a later statutory increase, because royalty is a statutory charge rather than a purely contractual one.

In BMM Ispat, the Supreme Court applied this to an iron ore royalty revision and held that minerals dispatched after the amendment attract the higher rate. Mining lessees should treat royalty liability as tied to the schedule in force at dispatch, and plan accordingly.
