In dealing with the questions that have been raised upon the foregoing provisions in their application to the circumstances that have been stated it is logical to begin with sub-s. (3) and its operation. For it is upon sub-s. (3) that the charge rests and it needs no argument to show that independently of the invalidating effect of s. 92 the facts fall exactly within its words. The appellants' firm did receive potatoes, being a commodity within the meaning of the Act, from a person other than the board, namely, from the Queensland Government Railways at Roma Street. The transaction in the course of which the commodity was so received involved no actual inter-State trade. Why should it not be within the application of sub-s. (3)? Certainly the language in which sub-s. (3) is expressed, interpreted naturally, and without the imposition of any artificial restriction by reference to constitutional limitations, extends to inter-State transactions upon which it cannot validly operate. To that extent it would be invalid. But it is a provision applying distributively, that is to say, it applies to each and every receipt of a commodity or purchase or sale or delivery within its terms separately and independently of every other receipt purchase sale or delivery. The very purpose of such provisions as s. 1A as understood in this Court and repeatedly applied is to establish a presumption that to the extent that its operation is within the power of the legislature a law is to be valid notwithstanding that as expressed it is in excess of power: see Bank of N.S.W. v. The Commonwealth [1] . Two answers were given, each depending upon a conception of the extent of the protection conferred by s. 92. The first arises upon the facts. It is as follows. When the appellants received the sixty-one bags of potatoes the offence, if offence there be, was complete and it mattered not that afterward they were sold in an intra-State transaction. The receipt of the goods was for and on behalf of a principal in New South Wales. Section 92, so it is argued, protects him, and his agent, from interference by State law in obtaining or accumulating goods for importation or sale into New South Wales. He cannot trade into New South Wales without goods and he is protected in the essential steps towards that end, not only with respect to goods devoted to sale for delivery into New South Wales, but in respect of goods which may or may not be disposed of in an inter-State transaction, pending a decision between inter-State and intra-State sale or delivery. There is no basis in fact for this contention. For when, before the arrival of the potatoes in Brisbane, Butt telephoned to the appellants' firm at Roma Street, Brisbane, and instructed them to take delivery of the consignment of potatoes and sell them on commission, that amounted to an instruction to sell them in the ordinary domestic trade of Queensland. Thus, before the actual receipt of the potatoes constituting the offence, the owner had decided upon intra-State sale of the potatoes. This is what the magistrate meant when he said that he was of opinion that when the owner of the potatoes decided to let them remain in Brisbane and be sold there, s. 15 had full application.
