Writ jurisdiction in tax matters may lie where statutory remedies are ineffective, and fiscal entries are read by commercial meaning.

Writ jurisdiction in tax matters may be invoked where statutory remedies are rendered ineffective by binding departmental directions, so the preliminary objection to maintainability failed. The court also held that a fiscal entry must be construed by the ordinary and commercial meaning of the expression used in that statute, not by definitions drawn from another enactment. Applying that approach, sulphur and saltpetre were not "ammunitions" under the Kerala General Sales Tax Act, even if they could be ingredients in explosives. The revisional notices and proposed reassessment were therefore without jurisdiction.

Issues: (i) Whether the writ petition was maintainable despite availability of statutory remedies, where departmental instructions rendered the remedy ineffective; (ii) Whether sulphur and saltpetre fall within Entry No. 18 of the First Schedule to the Kerala General Sales Tax Act as "ammunitions".

Issue (i): Whether the writ petition was maintainable despite availability of statutory remedies, where departmental instructions rendered the remedy ineffective.

Analysis: Ordinarily, writ jurisdiction is not invoked in taxation matters when statutory remedies are available. That rule is not absolute. Where the statutory hierarchy has been rendered ineffective by binding executive directions on the assessing and appellate authorities, pursuit of the ordinary remedies would serve no useful purpose. In such circumstances, interference under Article 226 is justified.

Conclusion: The writ petition was maintainable and the preliminary objection failed.

Issue (ii): Whether sulphur and saltpetre fall within Entry No. 18 of the First Schedule to the Kerala General Sales Tax Act as "ammunitions".

Analysis: The scope of a sales tax entry must be determined by the ordinary and commercial meaning of the expression used in that enactment. A definition or notification under the Arms Act cannot control the meaning of the same word in a different fiscal statute enacted for a different purpose by a different legislature. On that test, sulphur and saltpetre cannot be treated as "ammunitions", even if they may be used as ingredients in explosives.

Conclusion: Sulphur and saltpetre do not fall within the entry, and the proposed reassessment was without jurisdiction.

Final Conclusion: The revisional notices were unlawful, and the challenge to the attempted enhancement of sales tax failed.

Ratio Decidendi: In taxation matters, writ jurisdiction may be exercised where the statutory remedy is rendered ineffective by binding administrative directions, and the scope of a fiscal entry must be construed according to its ordinary and commercial meaning in that statute, not by reference to definitions in a different enactment.
