“9. Sri Bobde appearing for the appellants reiterated the contentions urged before the High Court. He submitted that the deduction of one per cent, in effect, amounts to taxing the raw material purchased outside the State or to taxing the sale of finished goods effected outside the State of Maharashtra. We cannot agree. Indeed, the whole issue can be put in simpler terms. The appellant (manufacturing dealer) purchases his raw material both within the State of Maharashtra and outside the State. Insofar as the purchases made outside the State of Maharashtra are concerned, the tax thereon is paid to other States. The State of Maharashtra gets the tax only in respect of purchases made by the appellant within the State. So far as the sales tax leviable on the sale of the goods manufactured by the appellant is concerned, the State of Maharashtra can levy and collect such tax only in respect of sales effected within the State of Maharashtra. It cannot levy or collect tax in respect of goods which are dispatched by the appellant to his branches and agents outside the State of Maharashtra and sold there. In law (apart from Rules 41 and 41-A) the appellant has no legal right to claim set-off of the purchase tax paid by him on his purchases within the State from out of the sales tax payable by him on the sale of the goods manufactured by him. It is only by virtue of the said Rules — which, as stated above, are conceived mainly in the interest of public — that he is entitled to such set-off. It is really a concession and an indulgence. More particularly, where the manufactured goods are not sold within the State of Maharashtra but are dispatched to out-State branches and agents and sold there, no sales tax can be or is levied by the State of Maharashtra. The State of Maharashtra gets nothing in respect of such sales effected outside the State. In respect of such sales, the rule-making authority could well have denied the benefit of set-off. But it chose to be generous and has extended the said benefit to such out-State sales as well, subject, however to deduction of one per cent of the sale price of such goods sent out of the State and sold there. We fail to understand how a valid grievance can be made in respect of such deduction when the very extension of the benefit of set-off is itself a boon or a concession. It was open to the rule-making authority to provide for a small abridgement or curtailment while extending a concession. Viewed from this angle, the argument that providing for such deduction amounts to levy of tax either on purchases of raw material effected outside the State or on sale of manufactured goods effected outside the State of Maharashtra appears to be beside the point and is unacceptable. So is the argument about apportioning the sale price with reference to the proportion in which raw material was
