Case Note & Summary

The appeals arose from a common judgment of the Karnataka High Court which upheld a retrospective amendment to the exemption entry for 'sugar' under the Karnataka Sales Tax Act, 1957. The appellant-assessees, Asia Sugar & Chemical Co. and Indian Sugar and General Exports Import Corporation Ltd., were dealers in sugar, including imported sugar. Originally, Entry 31 of the Fifth Schedule exempted 'sugar' from tax without any geographical restriction. The assessees claimed exemption for imported sugar, which was initially allowed by the assessing authority. However, by Karnataka Act No. 5 of 2001, the entry was amended retrospectively with effect from 1.4.1992 to confine the exemption to sugar 'produced or manufactured in India'. Consequently, the assessing authority issued notices proposing to levy tax on imported sugar for past periods, along with penalty and interest. The assessees challenged the retrospective amendment before the Karnataka High Court. A Single Judge struck down the retrospective operation as unreasonable, but the Division Bench reversed, upholding the amendment. The Supreme Court considered whether the retrospective amendment was valid. The court held that the amendment was clarificatory and intended to correct a mistake. It did not violate Articles 14, 19(1)(g), or 301 of the Constitution. The court noted that the assessees had not collected tax from their customers and could not be compelled to pay tax from their own pocket without any provision for reimbursement. However, the court held that the amendment itself was valid and the assessees were liable to pay tax, but without penalty and interest for the period prior to the amendment. The appeals were dismissed, but the court directed that no penalty or interest be imposed for the period prior to the amendment.

B) Sales Tax - Exemption - Interpretation of Exemption Entry - Karnataka Sales Tax Act, 1957, Section 8, Fifth Schedule Entry 31 - The court interpreted the original entry 'sugar' to mean all sugar, but the retrospective amendment confined it to sugar produced or manufactured in India.

Nature of Litigation

Civil appeals against judgment of Karnataka High Court upholding retrospective amendment to exemption entry for sugar under Karnataka Sales Tax Act.

Remedy Sought

Appellants sought to set aside the High Court judgment and declare the retrospective amendment as unconstitutional.

Filing Reason

Appellants challenged the retrospective amendment to Entry 31 of Fifth Schedule of KST Act, 1957, which confined exemption to sugar produced or manufactured in India, and consequent demand for tax, penalty, and interest for past periods.

Previous Decisions

Single Judge of Karnataka High Court struck down retrospective operation; Division Bench reversed and upheld the amendment.

Issues

Whether the retrospective amendment to Entry 31 of Fifth Schedule of Karnataka Sales Tax Act, 1957, confining exemption to sugar produced or manufactured in India, is valid? Whether the retrospective amendment violates Articles 14, 19(1)(g), and 301 of the Constitution of India?

Submissions/Arguments

Appellants argued that the retrospective amendment imposed an unreasonable burden as they had not collected tax during the relevant period and could not recover it from customers. State argued that the amendment was clarificatory and intended to correct a mistake, and that the assessees had no vested right to exemption.

Ratio Decidendi

A retrospective amendment to a tax exemption entry is valid if it is clarificatory and does not impose an unreasonable burden. The assessees had no vested right to exemption, and the amendment did not violate Articles 14, 19(1)(g), or 301. However, penalty and interest should not be imposed for the period prior to the amendment where the assessees acted in good faith.

Judgment Excerpts

These appeals raise a question concerning the true scope of an exemption granted to 'sugar' under the Karnataka Sales Tax Act, 1957, and the legal effect of a subsequent legislative amendment by which such exemption was confined to sugar 'produced or manufactured in India' with retrospective effect. The larger issue is whether a commodity which stood exempted under the statutory entry as it then read, and which was so treated by the taxing authority itself, can thereafter be retrospectively excluded from the exemption and subjected to tax for past periods, together with the incidents of penalty and interest.

Procedural History

The assessees filed writ petitions before the Karnataka High Court challenging the retrospective amendment. A Single Judge struck down the retrospective operation. The State appealed to the Division Bench, which reversed and upheld the amendment. The assessees then appealed to the Supreme Court by way of civil appeals and special leave petition.
