General tax-rate increases for fuel must follow schedule amendment, not a concession-based notification route.

A general increase in tax rates on petrol and diesel could not be made by notification under section 31 of the Puducherry VAT Act, because that provision was limited to reductions in tax payable, conditional concessions, and specified classes or transactions. The court held that a wholesale alteration of the applicable rate across all transactions had to be made by amending the Schedules under section 75, which is the proper mechanism for changing tax rates generally. As the impugned notification imposed an omnibus enhancement without special conditions or a limited class of dealers, it was issued under an inapplicable provision and was set aside.

Issues: Whether the Government could increase the rates of tax on petrol and diesel by notification under section 31 of the Puducherry Value Added Tax Act, 2007, or whether such a general alteration of tax rates could be made only by amending the Schedules under section 75 of the Act.

Analysis: Section 31 is a provision enabling the Government to notify reductions in the tax payable under the Act, subject to restrictions and conditions, and operates in the nature of a conditional concession for specified goods, classes of assessees, or transactions. Section 75, by contrast, empowers the Government to alter, add to, or cancel the Schedules, which is the mechanism for a wholesale change in the applicable rate of tax across the board. The notification impugned in this case did not carve out any special class of dealers or transactions and imposed no conditions for its operation; it simply enhanced the tax rates generally for petrol and diesel in specified regions. Such an omnibus change in rate could not be brought about under section 31 merely because the revised rates remained below the ceiling in the Schedule. The proper course was amendment of the Schedule under section 75.

Conclusion: The notification issued under section 31 to enhance the tax rates was without authority of law and could not stand.

Final Conclusion: The writ petition succeeded and the impugned notification was set aside for having been issued under an inapplicable statutory provision rather than by the prescribed schedule-amendment route.

Ratio Decidendi: A general and omnibus increase in tax rates affecting all transactions of a commodity must be made by amending the Schedule under the power to alter tax rates, and cannot be effected through a notification provision meant only for reduction of tax or conditional exemptions.
