Exemption by essential identity: spice powders retained the same character, and clarificatory substitution applied from the principal Act's commencement.

Alternative remedy did not bar the writ petitions because the earlier exemption litigation had substantially foreclosed the department's stand, making statutory appeal an empty formality. Chilli powder, coriander powder and turmeric powder were treated as the same goods as the original commodities for exemption purposes, since conversion into powder did not alter their essential character. The substitution of Entry 18 in the Fourth Schedule was held to operate from the commencement of the principal Act as a clarificatory amendment curing the omission. As the returns had been fully disclosed and accepted, the revision proceedings could not be sustained as escaped assessment and were set aside.

Issues: (i) Whether the writ petitions were not maintainable in view of the alternative appellate remedy. (ii) Whether chilly powder, coriander powder and turmeric powder were to be treated as the same goods as chilly, coriander and turmeric for exemption purposes. (iii) Whether the substitution made to Entry 18 in the Fourth Schedule by the amending Act operated from the commencement of the principal Act and whether the revision proceedings could be sustained as escaped assessment.

Issue (i): Whether the writ petitions were not maintainable in view of the alternative appellate remedy.

Analysis: The petitioners had already faced earlier litigation on the same exemption controversy, and the earlier view had substantially foreclosed the department's stand. In that situation, an appeal before the statutory authority would have been an empty formality. The Court also noticed that the petitioners were entitled to urge the merits notwithstanding the earlier round, since the impugned proceedings were fresh revision orders.

Conclusion: The objection based on alternative remedy was rejected, and the writ petitions were held maintainable.

Issue (ii): Whether chilly powder, coriander powder and turmeric powder were to be treated as the same goods as chilly, coriander and turmeric for exemption purposes.

Analysis: The Court relied on the earlier governmental treatment of the commodities, the exemption order and the departmental clarification, and the principle that a commodity does not lose its essential nature merely because it is converted into powder form. The authorities and the judicial precedent treated the original goods and their powder form as having the same substantial identity, with only a change in form and no change in essential character.

Conclusion: The powder forms were held to be the same goods and entitled to exemption.

Issue (iii): Whether the substitution made to Entry 18 in the Fourth Schedule by the amending Act operated from the commencement of the principal Act and whether the revision proceedings could be sustained as escaped assessment.

Analysis: The Court held that substitution, in the context of the statutory amendment, was intended to replace the earlier entry and cure the omission from the date the principal Act came into force. The amendment was treated as clarificatory and as relating back to the original schedule entry. Since the returns had been filed and accepted with full disclosure, the later revision could not be characterised as escaped assessment.

Conclusion: The substituted entry was given effect from the commencement of the principal Act, and the proceedings under the revision provision were unsustainable.

Final Conclusion: The impugned orders were set aside because the disputed commodities remained exempt and the revisional action was beyond jurisdiction.

Ratio Decidendi: Where an amendment substitutes an exemption entry to correct an omission concerning goods already treated as identical in substance, the substitution may operate from the commencement of the principal enactment, and reassessment cannot be sustained as escaped assessment when the relevant returns were already disclosed and accepted.
