Mining lease obligations and pit filling deduction recognised where restoration duties applied to continuing contracts.

Rule 34 of the Mineral Conservation and Development Rules, 1988 was treated as part of mining leases that incorporated rules framed from time to time under section 18 of the Mines and Minerals (Regulation and Development) Act, 1957. The rule required phased restoration, reclamation and rehabilitation of land affected by mining operations before completion and abandonment of the mine, so its effect was not confined to future leases in the abstract but extended to continuing obligations under subsisting contracts. On that basis, pit filling expenses incurred to restore mined land were held to be deductible, and the Tribunal's narrower construction was rejected as inconsistent with the rule's ecological purpose.

Issues: Whether rule 34 of the Mineral Conservation and Development Rules, 1988, applied to earlier mining leases and whether the assessee was entitled to deduction of pit filling expenses under that rule.

Analysis: The lease incorporated by reference the rules framed from time to time under section 18 of the Mines and Minerals (Regulation and Development) Act, 1957, so that rule 34 became part of the contractual obligations governing the mining operations. The rule required phased restoration, reclamation and rehabilitation of land affected by mining operations before completion and abandonment of the mine. The operative question was not merely whether the rule was retrospective in the abstract, but whether it affected continuing contractual obligations during the currency of the lease. On that basis, the obligation to fill pits and restore the land arose when the mining operations were being completed, and the rule had to be given effect in relation to such subsisting contracts. The construction adopted by the Tribunal was held to be erroneous, as it defeated the purpose of the rule and its public ecological objective.

Conclusion: The assessee was entitled to claim deduction for pit filling expenses, and the question was answered in the affirmative in favour of the assessee.
