Supreme Court bars penalty on retrospective sugar tax, upholds Karnataka amendment
Justices Aravind Kumar and Prasanna B. Varale upheld Karnataka’s 2001 retrospective withdrawal of the sugar exemption but barred penalty and back-dated interest on dealers who never collected tax.
A dealer who sold imported sugar in the mid-1990s treated it as exempt from Karnataka sales tax, and so charged nothing to buyers. Years later, a retrospective amendment declared that sugar had always meant sugar “produced or manufactured in India”, and the dealer was asked to pay tax, penalty and interest for those past sales.
On 13 July 2026, a division bench of the Supreme Court, comprising Justice Aravind Kumar and Justice Prasanna B. Varale, allowed the appeals in part. The Court held that Karnataka Act No. 5 of 2001 was validly enacted and constitutional, but that its retrospective operation could not carry penalty or back-dated interest against dealers who had acted under the earlier exemption. The judgment separates the validity of the amendment from the fairness of the consequences attached to it.
How the dispute reached the Court
The appellants, Asia Sugar & Chemical Co. of Devangere and M/s Indian Sugar and General Export Import Corporation Ltd., imported sugar and sold it within Karnataka and in inter-State trade during 1994 to 1996. They proceeded on the footing that imported sugar was exempt under the Fifth Schedule to the Karnataka Sales Tax Act, 1957, and did not collect sales tax from purchasers.
Section 8 of the KST Act exempted goods listed in the Fifth Schedule. Sugar appeared in that schedule. Before the 2001 amendment, the entry described sugar by reference to Column 3 of the First Schedule to the Additional Duties of Excise (Goods of Special Importance) Act, 1957. It used the word “sugar” without any words limiting the exemption to sugar produced or manufactured in India.
The original assessments granted exemption on imported sugar. The reassessment notice to Asia Sugar itself recorded that exemption had earlier been allowed on the basis of Entry 31-B and the decision in State of Kerala and Another v. State Trading Corporation of India Ltd.
Karnataka Act No. 5 of 2001 then inserted the words “produced or manufactured in India” after “Sugar”, with a deeming clause that they “shall be deemed always to have been inserted”. Reassessment notices followed under Section 9(2) of the Central Sales Tax Act, 1956 read with Section 12-A of the KST Act. In Asia Sugar’s case, a notice dated 16 January 2003 proposed reassessment for 3 December 1994 to 31 March 1995, and a reassessment order imposed tax of Rs.90,25,293.
A Single Judge of the Karnataka High Court, by order dated 26 May 2003, struck down the retrospective operation as violative of Article 19(1)(g), reasoning that it imposed an unreasonable burden on dealers who had not collected tax. The Division Bench, by common judgment dated 26 November 2007, reversed that finding, upheld the amendment and restored the reassessment proceedings.
Imported sugar was exempt before 2001
The Court held that prior to Karnataka Act No. 5 of 2001, imported sugar was covered by the exemption entry. The reference to the Additional Duties of Excise Act borrowed a description only to identify the commodity, not to import an origin-based limitation. The Court read the phrase “sugar as described” as significant, treating it as identifying the goods rather than confining them to Indian production.
Applying the rule of strict construction, the Court said it could not read words of limitation into a taxing entry which the Legislature had not used. The Court relied on Govind Saran Ganga Saran v. Commissioner of Sales Tax and Mathuram Agrawal v. State of Madhya Pradesh for the principle that in a taxing statute nothing is to be implied.
The Court found support in the Kerala High Court decision in State Trading Corporation of India Ltd. v. Assistant Commissioner (Assessment-I), Special Circle, Trivandrum, affirmed by the Supreme Court in State of Kerala and Another v. State Trading Corporation of India Ltd., which rejected the same origin-based argument on a similarly worded entry. The Department’s own conduct in granting exemption in the original assessments reinforced this reading. That the Legislature had to add the limiting words in 2001, the Court said, was the best indication that they were absent earlier.
The amendment is valid but not clarificatory
The Court held that Karnataka Act No. 5 of 2001 was within the State’s legislative competence under Entry 54 of List II and was constitutionally valid. The power to tax includes the power to grant, restrict and withdraw exemption. Exemption is a matter of fiscal policy, and no dealer holds a vested right to its continuance, following Kasinka Trading v. Union of India and Shrijee Sales Corporation v. Union of India.
On retrospectivity, the Court relied on Rai Ramkrishna v. State of Bihar, Epari Chinna Krishna Moorthy v. State of Orissa, Hiralal Rattanlal v. State of U.P. and P. Kannadasan v. State of Tamil Nadu to hold that retrospective fiscal legislation is not invalid merely because it operates backwards. The deeming clause made the legislative intent to give retrospective effect manifest.
The Court was clear that the amendment was not clarificatory. Once imported sugar was found to have been exempt before 2001, the amendment substantively withdrew that exemption. The Court distinguished this from a classical validating law under Shri Prithvi Cotton Mills Ltd. v. Broach Borough Municipality, which cures a defect in a levy that could otherwise have been lawfully imposed. Here, an exemption earlier available and acted upon was taken away.
Retrospectivity cannot be enforced with penal effect
The Court framed the harder question as how far the retrospective consequences could be enforced. It listed five facts: imported sugar was exempt before 2001; the Department completed the original assessments granting exemption; the assessees did not collect tax from purchasers; the transactions related to years long before the amendment; and reassessment was triggered only by the amendment.
Because sales tax is ordinarily collected from the purchaser, a dealer who treated goods as exempt retained nothing towards tax and could not later recover it from buyers. Against that backdrop, the Court held that penalty presupposes culpability or default, and could not be imposed on dealers who did not collect tax because the statute, the judicial understanding and the Department itself treated the commodity as exempt.
Interest, said the Court, is often compensatory, but where liability is created retrospectively and the assessee could not have collected tax at the time of sale, interest from the date of the original transaction would operate punitively. The Court read R.C. Tobacco (P) Ltd. v. Union of India, Empire Industries v. Union of India, D. Cawasji & Co. v. State of Mysore and Vatika Township as leaving retrospective operation open to constitutional scrutiny for reasonableness.
The balance struck was to uphold the amendment and permit determination of principal tax liability, while preventing the retrospective levy from assuming a punitive character.
Central Sales Tax computation
The assessees complained that inter-State sales were taxed at 10 per cent, ignoring Section 8(2) of the Central Sales Tax Act, 1956. The Court held that the validity of the KST Act amendment did not dispense with compliance with the Central Sales Tax Act, and directed recomputation of any inter-State liability strictly in accordance with that Act, including Section 8(2) where applicable, after hearing the assessees.
Order
The appeals were allowed in part. The Court affirmed the Division Bench judgment dated 26 November 2007 insofar as it upheld the validity of Karnataka Act No. 5 of 2001 and reversed the Single Judge’s declaration of invalidity.
The judgment was modified so that reassessment may continue only for determination of principal tax liability; no penalty shall be imposed or recovered for transactions before Karnataka Act No. 5 of 2001; interest, if leviable, shall run only from the date of lawful demand pursuant to reassessment and not from the original transaction or assessment period; and the assessing authority shall recompute liability, including inter-State sales, in accordance with the Central Sales Tax Act, 1956.
Any amount already recovered towards penalty or interest contrary to these directions is to be adjusted against lawful principal tax dues, and any excess refunded in accordance with law. The assessing authority is to complete the exercise after affording a hearing. There was no order as to costs.
