The Supreme Court of India, in a supplementary judgment delivered on July 31, 2024, clarified the temporal application of its nine-judge Constitution Bench decision on mineral taxation. The eight-judge majority directed that the ruling — which affirmed states' power to levy taxes on mineral-bearing lands — would apply prospectively, and that states could not raise retrospective tax demands for the period prior to April 1, 2005.
Background
Following the Constitution Bench's main judgment of July 25, 2024, which held that royalty on minerals is not a tax and that states retain independent taxation power under Entry 50 of List II, the critical question of temporal application remained unaddressed. The mining industry faced potential exposure to cumulative retrospective demands estimated at over Rs 1 lakh crore if states were permitted to recover arrears of taxes and cesses for past decades.
The Court had reserved the question of prospectivity for separate consideration. Multiple intervenors, including state governments and mining companies, made submissions on the fiscal consequences of either a fully retrospective or fully prospective application. State governments argued for the right to recover past dues, while mining companies urged that any new tax framework should apply only going forward to protect settled expectations and investments made in reliance on the India Cement (1989) position.
Key Holdings
The eight-judge majority issued the following directions on temporal application:
Prospective from April 1, 2005: The judgment's effect on states' taxation powers applies prospectively from April 1, 2005. States may levy and collect taxes on mineral-bearing lands for periods from this date onwards, in accordance with their respective legislative enactments.
No retrospective demands: States are not permitted to raise demands or recover taxes and cesses for periods prior to April 1, 2005 based on the overruling of India Cement.
Staggered payment: For demands pertaining to the period between April 1, 2005 and the date of the judgment (July 25, 2024), the Court directed that payments may be made in instalments spread over twelve years beginning April 1, 2026, to mitigate the immediate fiscal burden on the mining industry.
No interest or penalties on past dues: States may not levy interest or penalties on amounts that had remained unpaid during the pendency of the constitutional reference.
Existing refunds protected: Any refunds already issued by states pursuant to the earlier India Cement-based position need not be reversed.
Implications for Practitioners
The supplementary judgment provides essential certainty for mining companies, state treasuries, and their advisors. The twelve-year staggered payment window for retrospective demands (April 2005 to July 2024) represents a practical compromise that prevents immediate financial distress in the mining sector while preserving states' fiscal entitlements.
Corporate counsel advising mining companies should urgently quantify their clients' exposure for the April 2005-July 2024 period and prepare for structured payment negotiations with respective state governments. The prohibition on interest and penalties reduces the overall liability but the principal amounts may still be substantial for large-scale mining operations.
For state government lawyers, the judgment provides a clear roadmap for recovery — but the twelve-year window means that actual revenue realisation will be gradual. States that have already enacted taxation legislation should review whether their enactments require amendment to align with the constitutional framework as now settled by the nine-judge Bench.
The approach of prospective overruling with staggered compliance demonstrates a sophisticated judicial balancing of competing federalism, industry certainty, and fiscal interests.
