Retrospective withdrawal of sugar exemption permits principal tax recovery, but bars pre-amendment penalties and limits interest to lawful demand.

Imported sugar fell within the pre-2001 Karnataka sales tax exemption because the entry referred to the commodity without imposing an Indian-origin requirement. The later retrospective restriction of the exemption to sugar produced or manufactured in India was a substantive but constitutionally valid exercise of legislative competence. Its consequences were limited: principal tax could be reassessed and recovered, but pre-amendment penalty could not be imposed where dealers had acted under the earlier exemption and had not collected tax. Interest could accrue only from a lawful reassessment demand. Inter-State sales liability required recomputation under the applicable Central Sales Tax provisions, with impermissible penalty or interest adjusted against principal dues or refunded.

Issues: (i) Whether imported sugar was covered by the pre-2001 exemption entry under the Karnataka Sales Tax Act, 1957; (ii) whether the retrospective amendment restricting the exemption to sugar produced or manufactured in India was constitutionally valid; (iii) whether principal tax, penalty and interest could be enforced against dealers who had acted under the earlier exemption regime; (iv) what relief and computation directions were required, including for inter-State sales.

Issue (i): Whether imported sugar was covered by the pre-2001 exemption entry.

Analysis: The pre-2001 entry exempted "sugar" and, after 1992, described sugar by reference to the First Schedule to the Additional Duties of Excise (Goods of Special Importance) Act, 1957. The reference identified the commodity and did not incorporate an origin-based limitation. The entry contained no words restricting the exemption to sugar produced or manufactured in India. Strict construction of taxing and exemption provisions does not permit the addition of words not used by the Legislature. The Department's original assessments and the prevailing interpretation of similarly worded entries were consistent with exemption of imported sugar.

Conclusion: Imported sugar was covered by the exemption entry before Karnataka Act No. 5 of 2001.

Issue (ii): Whether the retrospective amendment restricting the exemption to sugar produced or manufactured in India was constitutionally valid.

Analysis: The amendment was substantive and not merely clarificatory because it altered the earlier legal position and retrospectively withdrew the exemption from imported sugar. The State Legislature possessed competence to levy sales tax and to grant, restrict or withdraw an exemption. Retrospective fiscal legislation is not unconstitutional merely because it is retrospective, provided legislative competence and constitutional limits are satisfied. The amendment clearly expressed retrospective intent and was not invalid solely on the ground of retrospectivity.

Conclusion: Karnataka Act No. 5 of 2001 was within legislative competence and constitutionally valid.

Issue (iii): Whether principal tax, penalty and interest could be enforced against dealers who had acted under the earlier exemption regime.

Analysis: The validity of the retrospective amendment did not require every consequence of retrospectivity to be imposed without qualification. The dealers had not collected tax, their original assessments had granted exemption, and the liability arose only because of the subsequent amendment. Principal tax could therefore be determined and recovered through lawful reassessment. Penalty, which presupposes culpability or default, could not be imposed for transactions effected before the amendment. Interest could not run from the original transactions or assessment periods where the liability was created retrospectively; it could run only from the date of lawful demand pursuant to reassessment.

Conclusion: Principal tax liability could be recovered, but no pre-amendment penalty could be imposed or recovered, and interest could be computed only from the date of lawful demand pursuant to reassessment.

Issue (iv): What consequential relief and computation directions were required, including for inter-State sales.

Analysis: Reassessment was limited to determination of principal tax liability in accordance with law. Liability relating to inter-State sales had to be recomputed by applying the applicable provisions and rate under the Central Sales Tax Act, 1956, including Section 8(2). Amounts already recovered towards impermissible penalty or interest were to be adjusted against lawful principal dues or refunded where no such dues remained, after giving the assessees an opportunity of hearing.

Conclusion: The reassessment proceedings were modified to permit determination of principal tax only, with lawful recomputation of inter-State sales liability and corresponding adjustment or refund of excess penalty or interest.

Final Conclusion: The retrospective restriction of the exemption was sustained, while the reassessment consequences were limited to protect dealers from penalty and interest burdens arising solely from the retrospective change in law.

Ratio Decidendi: A legislature may retrospectively withdraw or restrict a tax exemption within its legislative competence, but constitutional fairness may require that retrospective liability be confined to principal tax and not extended to penalty or interest for periods when the goods were lawfully treated as exempt and tax was not collected.
