It appears that at all relevant times the company held a licence to manufacture table margarine which contained a condition specifying 2,166 tons as being the maximum amount that might be manufactured by it during the currency of the licence. In fact during its currency it manufactured an amount in excess of that quantity and a large proportion of its output was applied in the fulfilment of orders received by it from customers in States other than New South Wales. It was for its failure to comply with this condition of its licence that the prosecution was launched. In an earlier case of Grannall v. Marrickville Margarine Pty. Ltd. [1] , the company was prosecuted for a breach of s. 22A (1) (b) of the Act in manufacturing table margarine without being the holder of a licence and it was contended on its behalf that the provisions of that paragraph, in so far at least as it purported to prohibit, except under licence, the manufacture of margarine intended to be supplied to buyers in other States, infringed the freedom of inter-State trade, commerce and intercourse which s. 92 guarantees. The evidence in that case showed that a substantial proportion of the company's output was intended by it to be applied and was in fact applied to the fulfilment of contracts between it and buyers in other States which called for the sale and delivery to those buyers of margarine from the company's premises. The contention failed. In their joint judgment Dixon C.J., McTiernan, Webb and Kitto JJ. pointed out [2] , that the prohibition in s. 22A (1) (b) was directed solely to the process of manufacture and did not restrict the freedom of the company to engage in inter-State trade and commerce. Their Honours agreed, of course, that the manufacture, production or importation of goods was an "essential preliminary condition" to any trade, inter-State or otherwise, in goods since without goods, there could be no trade in them. But that, they considered, did not make the manufacture, production or importation of goods trade and commerce among the States. They went on to say: "Two tendencies have grown manifest of late. One is to press the operation of s. 92 beyond the subject matter of trade, commerce and intercourse among the States so that it denies to the legislatures of this country the power to impose any prohibition, restriction or burden if its consequences could be seen in what was done or not done in the course of inter-State commerce. The other is to seek to extend the freedom which s. 92 guarantees to trade, commerce and intercourse among the States to antecedent or subsequent transactions on the plea that they are incidental, ancillary or conducive to inter-State transactions or necessarily consequential upon them. There is in truth nothing to justify such notions which would go far to exclude legislative power the existence of which has never been doubted. The defendant company's argument in the present case would, for example, appear to mean that there could be no effective prohibition of the importation of goods into Australia if they were merchandise intended to be bought and sold in inter-State trade. A customs tariff could not effectively be used to restrict importation if its purpose and operation were to prevent the dutiable goods going into inter-State trade" [1] . Fullagar J. said: "In order to bring the present case within the protection of s. 92, it was necessary for the defendant to put forward a conception of inter-State trade and commerce which, as my brethren have observed, has been put forward in several recent cases but has never been accepted. The substance of that view seems to be that operations such as production or manufacture are immune from legislative interference so long as it is possible that the producer or manufacturer may dispose of his product in inter-State trade, or at least if he intends to dispose of it in inter-State trade. I agree with what the Chief Justice and McTiernan, Webb and Kitto JJ. have said on this subject. There is no decision which gives any countenance to such a view. Section 92 protects only activities which themselves possess the character of inter-State trade, commerce, or intercourse" [2] . In the present case, counsel for the company submitted that Grannall's Case [3] was wrongly decided and should be overruled. In my opinion that submission should be rejected. The passages I have quoted from the judgments set out propositions with which I entirely agree and we have recently applied them to a case in which it was unsuccessfully argued that the prohibition under the Customs Act of the importation of aircraft intended to be used for the carriage of goods inter-State was an infringement of s. 92: Reg. v. Anderson; Ex parte Ipec-Air Pty. Ltd. [4] . Counsel's principal submission was, however, that the facts in the present case differ in vital respects from those in Grannall's Case [3] . They certainly differ in some respects and whether they lead to a different conclusion is the real question to be decided.
