Invalid delegation to enhance sales tax; relief limited prospectively after tax burden was passed on to consumers.

The power to enhance sales tax under the Punjab General Sales Tax Act was treated as a legislative function that could not be further delegated to the Chief Commissioner on the basis of the Adaptation Order, Article 239, or the General Clauses Act. The impugned notifications were therefore held to be without authority and were quashed. However, because the tax burden had already been passed on to consumers, the writ court limited the practical effect of its relief and refused retrospective restoration or refund-based benefit. The modified order operated prospectively only, leaving the revenue position protected to that extent.

Issues: (i) Whether the Chief Commissioner, Union Territory, Chandigarh, had authority to enhance the rate of sales tax under section 5(1) of the Punjab General Sales Tax Act, 1948 by issuing the impugned notifications; (ii) whether, after quashing the notifications, relief should operate retrospectively or only prospectively because the tax had already been recovered from consumers.

Issue (i): Whether the Chief Commissioner, Union Territory, Chandigarh, had authority to enhance the rate of sales tax under section 5(1) of the Punjab General Sales Tax Act, 1948 by issuing the impugned notifications.

Analysis: The power to determine or enhance the rate of sales tax was treated as a legislative power, not a merely administrative or executive function. The Adaptation Order and the reference to article 239 of the Constitution of India did not authorise the President or the Administrator to further delegate that legislative power to the Chief Commissioner. Section 3(8)(b)(iii) of the General Clauses Act, 1897 was held to relate only to the Administrator acting within the scope of authority under article 239, and not to convert the delegated executive arrangement into a power to alter tax rates under the State enactment.

Conclusion: The impugned notifications enhancing the rate of sales tax were without authority and were quashed.

Issue (ii): Whether, after quashing the notifications, relief should operate retrospectively or only prospectively because the tax had already been recovered from consumers.

Analysis: Although the notifications were invalid, the Court considered the equitable effect of granting full retrospective relief where the petitioners had already passed on the tax burden to consumers. In writ jurisdiction, discretionary relief may be withheld where technical entitlement does not correspond to actual loss or injustice. On that basis, the earlier direction was modified so that the petitioners would not remain liable under the impugned notifications after the date of the earlier order, but the declaration of invalidity would not restore retrospective benefit.

Conclusion: Relief was confined prospectively and the petitioners were not given retrospective immunity or refund-based relief.

Final Conclusion: The notifications were held invalid for want of authority, but the practical relief was limited to prospective effect only, leaving the revenue position protected to the extent indicated by the modified order.

Ratio Decidendi: The power to enhance sales tax is a legislative power that cannot be further delegated unless such delegation is clearly authorised, and even where invalidity is found, writ relief may be limited prospectively on equitable grounds where the tax burden has been passed on to consumers.
