Writ jurisdiction and disputed taxability: taxing authorities should first ? determine transaction character before constitutional challenge.

Where a fiscal statute provides a complete mechanism for assessment, appeal and revision, disputed questions about the true character of a transaction should ordinarily be determined by the taxing authorities, not in writ jurisdiction. The writ court may interfere only where there is a clear issue of legislative competence, constitutional restriction, patent lack of jurisdiction, or serious procedural illegality. A tax lawfully imposed within legislative competence does not, by itself, infringe fundamental rights under Article 19(1)(f) or 19(1)(g). The taxability of motor spirits and lubricants, including questions of ownership and sale, was therefore left to the statutory authorities under the Act.

Issues: (i) Whether the High Court should, in writ jurisdiction, decide a disputed question as to the true nature of the transaction instead of leaving the matter to the statutory taxing authorities; (ii) Whether levy of tax on consumption of motor spirits and lubricants could be struck down as unconstitutional or as infringing fundamental rights.

Issue (i): Whether the High Court should, in writ jurisdiction, decide a disputed question as to the true nature of the transaction instead of leaving the matter to the statutory taxing authorities.

Analysis: The Act provided a complete machinery for assessment, appeal, and revision. Where the liability to tax depends on the true character of the transaction and that character is disputed, the proper course is for the taxing authorities to determine the matter in the first instance. The writ court may interfere where legislative competence, constitutional restriction, patent want of jurisdiction, or serious procedural illegality is shown, but it should not ordinarily embark on fact-finding about the taxable nature of a transaction.

Conclusion: The High Court erred in deciding the matter on an issue not raised and in bypassing the statutory machinery.

Issue (ii): Whether levy of tax on consumption of motor spirits and lubricants could be struck down as unconstitutional or as infringing fundamental rights.

Analysis: The charging provision and definition of retail sale did not show any lack of legislative competence on the face of the statute. A tax lawfully imposed within legislative competence does not, by itself, infringe the rights guaranteed under Article 19(1)(f) and Article 19(1)(g). Whether the goods belonged to the company and whether their use amounted to sale were matters for determination under the Act by the assessing authority.

Conclusion: The constitutional challenge failed, and the question of taxability had to be decided by the statutory authorities.

Final Conclusion: The appeal was not sustainable, and the dismissal of the writ petition was maintained while leaving the assessee free to pursue the statutory remedies on the merits of the ownership and sale questions.

Ratio Decidendi: Where a fiscal statute provides an adequate assessment and appellate mechanism, and the liability turns on disputed questions of fact, the High Court should ordinarily not decide taxability in writ jurisdiction unless a clear constitutional or jurisdictional infirmity is shown.
