3 Under clause 1(ii), property in goods will continue to reside in BHP despite a purported sub-sale by the customer if two conditions are satisfied: first, property has not passed from BHP to the customer at or before the time of the sub-sale; and, second, the customer does not, as agent of BHP as undisclosed principal, transfer to the sub-buyer property retained by BHP. I shall consider these two matters in reverse order.
4 As to whether the customer becomes BHP's agent, empowered to transfer property residing in BHP, it is true that there is no statement, in terms, that the customer may sell as BHP's agent. But there are two paragraphs, (f) and (g), containing acknowledgments by the customer expressed to apply "if it sells any of the product". In the case of par (g), the full form of words is, "if it sells any of the product before making full payment for them". The last six words do not appear in par (f) but must, in my view, be implied: if the customer sells after making full payment to BHP, the customer is necessarily selling its own property since, on any view, retention of property by BHP does not continue beyond that full payment.
5 By pars (f) and (g) which, for this reason, I consider to reflect the parties' bargain in the event of sale by the customer before full payment, the customer acknowledges, first, that the sale it makes is made as the "fiduciary agent" of BHP; second, that "such sale shall not give rise to any obligations on the part of BHP"; and, third, that the part of the sale proceeds equal to the amount owing to BHP will be held by the customer in a separate account in trust for BHP.
6 On one view, being the view advanced by Mr Epstein SC on behalf BHP, pars (f) and (g) do not confer any power of the customer to sell as agent of BHP and are concerned only with spelling out the consequences of what is a conversion, a breach of bailment or a breach of contract - or perhaps all three.
7 Mr Epstein pointed out that there is nothing in the provisions to prevent the customer selling at a gross under-value or in an uncommercial transaction involving a related party, and that BHP cannot be taken to have intended that the customer would be empowered to sacrifice BHP's interests in that way. Mr Epstein also pointed to the aspect of par (f) which says that a sale by the customer will not give rise to obligations on the part of BHP. An obligation to give property is fundamental to a sale, so that denial of all obligations on the part of BHP (in which property resides) is inconsistent with the notion that the customer can pass that property to a sub-buyer.
8 I am unable to accept that this reflects the intent manifested by pars (f) and (g) or, for that matter, the terms and conditions as a whole. It seems to me quite easy - I would go so far as to say essential - to imply a power to sell, if such an implication is necessary. I do question, however, whether it is necessary since the statement by the owner to a bailee, "If you sell, you do so as my agent", seems to me necessarily to mean, "You may sell as my agent", without any need for an implied term and simply as a matter of construction of the words.
9 Mr Epstein's point that the customer as seller may sacrifice BHP's interests as owner is I think hard to make in view of the words "fiduciary agent". The reference to "fiduciary agent" seems to me to convey two messages over and above mere agency. The first is that there is an intention to adopt a legal label used to identify a situation where tracing applies. The many cases applying the principles in Re Hallett's Estate (1880) 13 ChD 696 and Re Diplock [1948] 1 Ch 465 often resort to the term "fiduciary agent" as an indicator in such a situation. Whether the adoption of the label is sufficient to achieve the objective of making the agent a fiduciary in such a way as to attract tracing rules is a question in its own right, which does not arise here. The question is discussed in Puma Australia Pty Ltd v Sportsman's Australia Ltd (No 2) [1994] 2 QdR 159. Fiduciary relationships cannot, of course, be created merely by contract and, in the absence of some indication of intention that the principal's interests must be afforded precedence, an agent as such is not necessarily a fiduciary: see Hospital Products Ltd v United States Surgical Corporation (1984) 156 CLR 41 at 71-72 per Gibbs CJ.
10 This leads to the second message I consider to be conveyed by the label "fiduciary agent", namely, a message of reinforcement that the agent, in exercising the agency, is required to subordinate its own interests and must, as in the case of a fiduciary, prefer the interests of his principal. That means, in the present context, that the customer in on-selling must safeguard and promote the interests of BHP in being paid its original contract price, so that a sale which will not achieve that end, although effectively made by the agent in exercise of the agency, is made in breach of the contract between principal and agent. The point is not so much whether the customer becomes a fiduciary (that is, whether the agency carries a fiduciary characterisation), but that the contract, by use of the word "fiduciary", requires him to act as if he were a fiduciary, regardless of whether technically he is one or not.
11 As to the point that any sale does not give rise to any obligations on the part of BHP, I do not consider that to be an indication against a power for the customer to sell as agent. It is rather an indication that the agent of BHP, as seller, cannot give warranties or assurances binding on BHP. To refer to a sale, and to contemplate sale by an agent, in circumstances where no obligation to pass property can be imposed by the agent on the seller is a nonsense. The obligations precluded are obligations subsisting beyond completion of the sale. By completion of the sale, I mean the passing of property. What is precluded is some continuing exposure for BHP over and above what the customer as agent does by transferring property to the sub-buyer.
12 I should now refer to the decision of the High Court in Associated Alloys Pty Ltd v ACN 001 452 106 Pty Ltd (2000) 202 CLR 588. I do so not because that case involved sub-sale of unaltered goods in relation to which there was a provision allowing sale by the customer as agent of the party equivalent to BHP, but because of the form of the clause with which the High Court did have to deal, being the clause about incorporation of the particular goods into something produced by a manufacturing process.
13 The relevant clause began with the following words:
"In the event that the [Buyer] uses the goods/product in some manufacturing or construction process of its own or some third party, then the [Buyer] shall hold such part of the proceeds of such manufacturing or construction process as relates to the goods/product in trust for the [Seller]."
