Mineral royalty computation and fiscal policy deference: clarificatory explanations upheld, while consultation on coal-related anomaly was ordered.

In fiscal and economic regulation of mineral royalty, the Court treated the computation framework as a policy matter warranting wide legislative and executive latitude. It held that the explanations to Rule 38 of the Mineral Concession Rules, 2016 and Rule 45 of the Mineral Conservation and Development Rules, 2017 were clarificatory and harmonising in nature, and not an impermissible enlargement of the rules; they were therefore not struck down for manifest arbitrariness. The Court also did not finally invalidate the differing treatment of coal in excluding royalty and certain mineral fund contributions, but directed the respondents to complete the pending consultation and take a final decision within the time granted.

Issues: (i) Whether the explanations appended to Rule 38 of the Mineral (Other than Atomic and Hydrocarbons Energy Minerals) Concession Rules, 2016 and Rule 45 of the Mineral Conservation and Development Rules, 2017 are unreasonable and manifestly arbitrary in violation of Article 14; (ii) Whether the exclusion of royalty and contributions towards the District Mineral Foundation and the National Mineral Exploration Trust for coal, but not for other minerals, is unreasonable and manifestly arbitrary.

Issue (i): Whether the explanations appended to Rule 38 of the Mineral (Other than Atomic and Hydrocarbons Energy Minerals) Concession Rules, 2016 and Rule 45 of the Mineral Conservation and Development Rules, 2017 are unreasonable and manifestly arbitrary in violation of Article 14.

Analysis: The computation of royalty in the mineral sector was treated as a matter of economic policy, where legislative and executive choices are entitled to wide latitude. The explanations were read as clarificatory and harmonising the main provisions, not as enlarging the scope of the rules. In the absence of a demonstrated statutory transgression or constitutional breach, the Court declined to strike them down on the ground of manifest arbitrariness merely because the mechanism may produce a cascading monetary effect.

Conclusion: The challenge to the explanations on this ground was not accepted.

Issue (ii): Whether the exclusion of royalty and contributions towards the District Mineral Foundation and the National Mineral Exploration Trust for coal, but not for other minerals, is unreasonable and manifestly arbitrary.

Analysis: The Court noted that greater deference is due in fiscal and economic matters and that different treatment of coal and other minerals is not invalid merely because the computation methods differ. At the same time, the Court noticed the acknowledged anomaly in the existing methodology and the pending public consultation for possible amendment. The Court therefore refrained from making a final constitutional pronouncement striking down the differentiation, but directed the respondents to conclude the consultation and take a decision within a fixed time.

Conclusion: The challenge on this ground was not finally upheld, though a time-bound administrative decision was directed.

Final Conclusion: The impugned explanations were not struck down, but the respondents were required to complete the consultative process and take a final decision on the cascading royalty issue within the time granted by the Court.

Ratio Decidendi: In economic and fiscal regulation, particularly in the computation of royalty on minerals, courts will not strike down a policy choice as manifestly arbitrary unless it exceeds statutory authority or violates the Constitution, and an explanation that merely clarifies the main rule without enlarging it is valid.
