Writ remedy, sales tax exemption and royalty-based purchase tax: Supreme Court principles on incentives and mining lease payments.

Alternative statutory remedies do not bar writ jurisdiction as an absolute rule; it remains available in exceptional cases such as lack of jurisdiction or natural justice concerns, and the High Court's decision to entertain the writ petitions was upheld. Sales tax exemption under the incentive notifications depended on satisfaction of the notified eligibility conditions, including timely registration, commencement of commercial production after the notified date, capital investment and employment requirements; those conditions were found satisfied, and revisional interference with the exemption was not sustainable. Royalty paid under a mining lease was treated as consideration for the right to extract minerals, not as sale or purchase price, so it did not attract purchase tax.

Issues: (i) Whether the High Court was justified in entertaining the writ petitions despite the availability of statutory appellate and revisional remedies; (ii) whether the assessee was entitled to sales tax exemption under the incentive notifications from the date of commencement of commercial production and whether the revisional interference with the assessment orders was valid; (iii) whether royalty paid under the mining lease attracted purchase tax.

Issue (i): Whether the High Court was justified in entertaining the writ petitions despite the availability of statutory appellate and revisional remedies.

Analysis: The availability of an alternative remedy is a rule of discretion and self-imposed restraint, not an absolute bar. Writ jurisdiction may be invoked where there is lack of jurisdiction, breach of natural justice, abuse of process, or other exceptional circumstances showing that the statutory remedy would be inefficacious. On the facts, the High Court had recorded sufficient reasons for entertaining the writ petitions and the matter did not call for interference on this ground.

Conclusion: The writ petitions were maintainable and the objection based on alternative remedy failed.

Issue (ii): Whether the assessee was entitled to sales tax exemption under the incentive notifications from the date of commencement of commercial production and whether the revisional interference with the assessment orders was valid.

Analysis: The incentive notifications and the revised rules showed that registration with the Empowered Committee within the prescribed period, commencement of commercial production after the notified date, prescribed capital investment, and the requisite employment strength were the operative eligibility conditions. The assessee had been registered within the relevant period, had been specifically identified in the later notification, and had satisfied the material conditions for the exemption. The Court also noted that the assessment orders fixing the date of entitlement had merged in the appellate orders, limiting the revisional authority's power. The objections based on alleged defects in declaration forms were treated as technical and not as a substantive denial of the benefit, particularly when opportunity to cure defects had been sought.

Conclusion: The assessee was entitled to the exemption, and the revisional withdrawal of the benefit could not be sustained.

Issue (iii): Whether royalty paid under the mining lease attracted purchase tax.

Analysis: Royalty under a mining lease is not the sale price or purchase price of goods; it is a payment for the right to extract minerals, distinct from a tax on purchase. The mining lease involves a profit a prendre and the consideration structure of dead rent and royalty does not convert royalty into a taxable purchase consideration. The Court followed the settled position that royalty is not liable to purchase tax in the manner suggested by the State.

Conclusion: Royalty did not attract purchase tax.

Final Conclusion: The appeals failed on all substantial issues and the High Court's relief in favour of the assessee was not disturbed, except for the limited procedural directions recorded in relation to the pending revision notices.

Ratio Decidendi: A writ petition may be entertained despite alternative statutory remedies in exceptional cases, incentive exemptions must be granted where the notified eligibility conditions are satisfied, and royalty under a mining lease is not purchase price so as to attract purchase tax.
