But this is not the occasion to pursue the matter; for the evidence establishes quite clearly, in my opinion, that the business in which the plaintiffs were engaged before the board intervened, and by reason of which alone they have an interest to maintain this action, did not include any sales in inter-State trade. It involved, of course, inter-State intercourse in the form of communications and remittances passing between the plaintiffs, and it involved the inter-State consignment and carriage of goods. Freedom in respect of these matters cannot be legislatively denied or burdened. But the application of s. 70 (c) is at the point of sale only; and all the sales in which the plaintiffs were concerned were sales in intra-State trade. They were made in Adelaide, pursuant to orders solicited and given in Adelaide, for the supply in Adelaide of goods described only as roast seasoned pork, without any stipulation being made, expressly or impliedly, as to the place from which the goods should be obtained by the seller for the purpose of fulfilling the orders. The fact that Williams found it convenient, or commercially necessary, to equip Thompson with the goods required by the customers by sending him from Victoria pork derived from carcasses which had not been branded under the South Australian Act is not a fact which suffices to bring the sales themselves within the protection of s. 92 of the Constitution. All agreements for sale made by Williams, or by Thompson on behalf of Williams, were similar in kind to those made according to the third of the methods of trade considered in W. & A. McArthur Ltd. v. Queensland [1] , and none of them resembled those made according to the fourth of those methods. This situation was squarely faced by counsel for the plaintiffs, but they argued that, in the circumstances of this case, from order to delivery was one inter-State transaction. They submitted that the sales made in Adelaide were the culmination of a form of inter-State activity on the part of the plaintiffs which was effectively ended by the prohibition in s. 70 (c), and for that reason the prohibition could not be said to leave the plaintiffs' inter-State trade, commerce and intercourse absolutely free.
