Plain-language tax classification upheld for raw and frozen seafood, sustaining purchase tax and rejecting the constitutional challenge.

An amended sales tax entry that expressly separated raw shrimps, prawns and lobsters from frozen or processed varieties was construed according to its plain language, with the words "other than" treated as a deliberate legislative distinction. On that basis, raw purchases and the later processed or frozen export commodity were regarded as different for the entry, supporting purchase tax on the locally purchased raw goods. The constitutional challenge also failed: the State Legislature was held competent to classify goods for sales tax purposes, the entry was not inconsistent with the Central Sales Tax Act, and the raw/frozen distinction was treated as a rational classification. The retrospective amendments were upheld as valid.

Issues: (i) Whether raw shrimps, prawns and lobsters and frozen or processed shrimps, prawns and lobsters are the same commodity for the purpose of entry 13a of the Third Schedule to the Karnataka Sales Tax Act, 1957, and whether the assessees were liable to purchase tax on the raw goods purchased locally. (ii) Whether entry 13a, as amended, was unconstitutional for want of legislative competence, for conflict with section 5(3) of the Central Sales Tax Act, 1956, or as offending article 14 of the Constitution of India.

Issue (i): Whether raw shrimps, prawns and lobsters and frozen or processed shrimps, prawns and lobsters are the same commodity for the purpose of entry 13a of the Third Schedule to the Karnataka Sales Tax Act, 1957, and whether the assessees were liable to purchase tax on the raw goods purchased locally.

Analysis: The statutory entry, as amended, expressly separated raw shrimps, prawns and lobsters from frozen shrimps, prawns and lobsters. The Court applied the plain language of the entry and held that the use of the words "other than" showed a deliberate legislative distinction. The common parlance approach to sales tax entries was applied, but the amended entry controlled the result because the legislature had consciously excluded frozen goods from the taxable category. On that construction, the petitioners purchased raw goods and after processing and freezing exported a different commodity for the purpose of the entry.

Conclusion: The two varieties were distinct for the purposes of the entry, and the raw purchases were liable to purchase tax under the Act.

Issue (ii): Whether entry 13a, as amended, was unconstitutional for want of legislative competence, for conflict with section 5(3) of the Central Sales Tax Act, 1956, or as offending article 14 of the Constitution of India.

Analysis: The State Legislature was competent under article 246 and entry 54 of List II to classify goods for sales tax purposes. The entry did not trench upon Parliament's field under the Central Sales Tax Act because it regulated local taxability of the commodity and did not alter the legal tests governing export sales. The classification between raw and frozen goods was held to be based on real and intelligible differences and to bear a rational relation to revenue collection. The retrospective amendments were also upheld.

Conclusion: The constitutional challenge failed, and entry 13a was held valid.

Final Conclusion: The writ petitions were dismissed, and the assessment of purchase tax on the raw purchases of shrimps, prawns and lobsters was sustained.

Ratio Decidendi: Where a taxing entry expressly distinguishes raw goods from processed or frozen goods by clear words such as "other than", the Court must give effect to that legislative classification in its plain sense, and such a distinction will ordinarily sustain both the levy and the constitutional validity of the provision if it is rational and within legislative competence.
