Oil-seeds classification barred additional cess where the State tax ceiling for coconut and copra was already reached.

Coconut was construed as an oil-seed because it is the reproductive unit of the coconut plant and yields oil, and copra was treated similarly as the dried kernel and direct source of coconut oil. On that classification, both commodities were goods of special importance under Article 286(3) of the Constitution and subject to the statutory ceiling on sales tax under section 15 of the Central Sales Tax Act. Because the Mysore Sales Tax Act already imposed tax at the maximum permissible rate, no further cess could lawfully be levied under the Madras Commercial Crops Markets Act. The cess demand was therefore without authority of law and liable to be quashed.

Issues: Whether coconut and copra fall within the expression "oil-seeds" in section 14(vi) of the Central Sales Tax Act, 1956, and whether, in consequence, the levy of cess under section 11 of the Madras Commercial Crops Markets Act, 1933, was barred because the maximum permissible sales tax had already been imposed under the Mysore Sales Tax Act, 1957.

Analysis: The expression "oil-seeds" in section 14(vi) of the Central Sales Tax Act, 1956, was construed in the light of the ordinary meaning of "seed" and the admitted fact that coconut is the reproductive unit of the coconut plant and yields oil. Coconut was therefore held to be an oil-seed. Copra, being the dried kernel of the coconut and an equally direct source of coconut oil, was treated as falling within the same expression. Once coconut and copra were so classified, they became goods of special importance under Article 286(3) of the Constitution of India, attracting the ceiling in section 15 of the Central Sales Tax Act, 1956. Since section 5(4) of the Mysore Sales Tax Act, 1957, read with Schedule IV to that Act, already imposed tax at the maximum permissible rate of two per cent, the State could not lawfully demand any further cess under section 11 of the Madras Commercial Crops Markets Act, 1933.

Conclusion: Coconut and copra were held to be oil-seeds, and the impugned cess demand was without authority of law and liable to be quashed in favour of the assessee.

Ratio Decidendi: Where goods are declared by Parliament to be of special importance, a State cannot impose a further sales-tax levy that exceeds the ceiling fixed by Parliament; commodities that are the seed or dried kernel from which oil is extracted may fall within "oil-seeds" for that purpose.
