Retrospective VAT explanation cannot withdraw an existing input tax rebate without amending the substantive provision.

The article examines whether a retrospective explanation inserted into the Madhya Pradesh VAT Act could require apportionment of input tax rebate where manufacture produced both Schedule I and Schedule II goods. It states that the rebate under the existing provision remained available for taxable raw material used in Schedule II goods, and that an explanation cannot enlarge the main enactment or withdraw a statutory benefit without amending the substantive charging or rebate provision. On that reasoning, the retrospective apportionment mechanism was held unsustainable and applicable only prospectively, leaving the earlier full input tax rebate intact.

Issues: Whether the explanation inserted in Section 14 of the Madhya Pradesh Value Added Tax Act, 2002 by the Madhya Pradesh Value Added Tax (Second Amendment) Act, 2014, with retrospective effect from 01.04.2006, could validly require apportionment of input tax rebate where the manufacturing process yielded both Schedule I and Schedule II goods.

Analysis: The petitioners were entitled under Section 14(1)(a)(2) of the Madhya Pradesh Value Added Tax Act, 2002 to input tax rebate on purchases of taxable raw material used in manufacture of Schedule II goods. The prior view of the Court had held that the existence of a tax-free by-product did not justify proportionate disallowance of rebate. The amendment introduced an explanation directing apportionment of input tax between Schedule I and Schedule II goods, but the underlying charging and rebate provisions were not amended so as to alter the incidence of tax. An explanation may clarify an existing provision, but it cannot enlarge the main enactment or take away a statutory benefit already conferred. A retrospective amendment of this nature, in substance, sought to change the basis of rebate without amending the operative incidence provision, and therefore could not operate to deny the full rebate for the earlier period.

Conclusion: The retrospective operation of the explanation was not sustainable, and the apportionment mechanism introduced by the amendment could apply only prospectively.

Final Conclusion: The writ petition succeeded and the petitioners retained entitlement to full input tax rebate for the period prior to the prospective operation of the amendment.

Ratio Decidendi: An explanation cannot be used to retrospectively alter the incidence of tax or withdraw a statutory rebate unless the substantive charging or rebate provision is amended accordingly.
