First sale tax remains a sales tax, not excise, where the levy falls on the seller's capacity as seller.

A tax on the first sale of goods manufactured or produced in the Province remains a tax on the sale of goods within provincial competence, not a duty of excise. The decisive distinction is that excise is levied on manufacture or production, whereas sales tax is levied on the occasion of sale. Even where the seller is also the manufacturer or producer, the levy attaches to him in his capacity as seller, so the same economic burden does not create constitutional overlap or alter the legal character of the tax. Comparative foreign authorities were not treated as a basis for narrowing the Province's clear taxing power.

Issues: Whether a tax imposed on the first sale of goods manufactured or produced in the Province under the Madras General Sales Tax Act was a tax on the sale of goods within provincial competence or a duty of excise reserved to the Centre.

Analysis: The taxing scheme in the constitutional distribution of powers distinguished between duties of excise, which were levied on the manufacturer or producer in respect of manufacture or production, and taxes on the sale of goods, which were levied on the occasion of sale. The Court held that a first sale remains a sale taxable by the Province even if the seller is also the manufacturer or producer, because the levy is imposed on him qua seller and not qua manufacturer. The fact that the tax may economically fall upon the same person who is also subject to excise does not create legal overlap or convert the sales tax into an excise duty. Comparative foreign authorities did not justify cutting down the clear provincial power to tax sales.

Conclusion: The tax on first sales was within the provincial power to tax sales of goods and was not a duty of excise.

Ratio Decidendi: Under the constitutional allocation of fiscal powers, a tax on the sale of goods is not transformed into a duty of excise merely because the sale is the first sale made by the manufacturer or producer; the relevant inquiry is whether the levy is imposed on manufacture or on sale.
