See also Kitto J at 535 - 536 and Menzies J at 537. It is a question of fact in each case whether the negotiable instrument is taken in complete satisfaction of the original debt or merely as a conditional payment, the onus lying on the party alleging that the negotiable instrument operates as a complete satisfaction of the original debt: Armco (Australia) Pty Ltd v Federal Commissioner of Taxation (1948) 76 CLR 589, 595."
15 Mr Einstein submits that if the Credex dollars be valueless, the vendor is entitled to look to the defendant for payment in Australian dollars and, what is more, the purchase price, not having been satisfied pro tanto by the delivery of Credex dollars, a vendor's lien arises in favour of the vendor for the unpaid portion of the purchase price. He submits that the transaction does not evince an intention by the parties that the receipt of the Credex dollars should satisfy the defendant's obligation to pay, whatever the worth or lack of worth of the Credex dollars.
16 The submissions put by Mr R J Colquhoun, of counsel for the defendant, were as follows: (1) There was no evidence that the trading scheme was not operating in May 2002 despite the deregistration of the exchange company. (2) Neither the vendor nor the defendant was a member of the Exchange. They were both people operating outside the Exchange. Therefore the non existence of the Exchange was irrelevant. (3) Payment of the Credex dollars was made in accordance with the contract and discharged the defendant's obligation, so that no vendor's lien arose. (4) There was no evidence that the Credex dollars were valueless, or of less value than one Credex dollar equals one Australian dollar, or that the Credex dollars delivered were not to the value of $510,000 Australian. (5) There was no evidence that the rules which were in evidence were the rules governing the exchange scheme at the time of the exchange or settlement of the contract and that there should be evidence of the rules at the relevant time.
17 To deal first with this submission (5), I should say that the rules when tendered in evidence were not objected to as irrelevant. Furthermore, the evidence shows that the membership application and the rules were current as at December 2001. There is, of course, a presumption of continuance. The contract was only some six months later in May 2002. More importantly, CNATE was deregistered in February 2002, only some two months after it is plain that the rules in evidence were current. They are hardly likely to have been changed after the company was deregistered. I find on the evidence before me that the membership application in evidence and the rules of trading were current at the time of the contract.
18 As to submission (1), Mr Colquhoun said there was no evidence that the scheme was not operating in May 2002. However, more importantly, there is no evidence that it was operating in May 2002 or has indeed operated at any time after deregistration of CNATE in February 2002. In my view, it could not have had any valid operation once the exchange company, which was contractually provided to be the operator, was non-existent and among people of whom the vital description was that they were members of that company, which was no longer in existence.
19 Submission (2) was that neither party to the contract was a member of CNATE at the time of the contract, so that the non existence of CNATE was irrelevant. That neither was a member is quite correct, but is hardly to the point. There was nothing in the scheme, so far as it was in evidence, that prevented people holding entitlement to Credex dollars who were not members of CNATE. What membership of CNATE provided for was the ability to carry out trading deals with other members of CNATE. The defendant was obviously able to obtain Credex dollars, although not a member of the exchange company, and to deliver them in purported performance of its obligations under the contract. The vendor could presumably make use of them by way of trading, either by itself subsequently becoming a member of CNATE or, as it did, by procuring their transfer to a person, in this instance Foxel, who was a member of CNATE. However, none of that is to the point, in my view, if the Credex dollars were themselves valueless, ie, Foxel could make no use of them because it was no longer able to enter into exchange transactions with other members of the exchange company.
20 As to submission (3), I accept Mr Einstein's submissions about the status of, and the parties' intention in relation to, the obligation of payment. This is not a case in which the parties' intention as evinced was that the Credex dollars, whatever their value, were, if delivered, to be taken as due performance of the contract by the defendant without reference to the question of whether or not they were of the equivalent value in Australian dollars. It was not the intention of this contract, in my view, that the delivery of the Credex dollars, whatever their value, was a due fulfilment of the terms of the contract, nor was delivery of Credex dollars the exclusive means by which the obligation could be fulfilled. It could also be fulfilled, as appropriate, by the payment of ordinary currency in the stipulated amount.
21 Submission (4) was that there was no evidence that the Credex dollars were valueless or of less value than one to one with the Australian dollar. However, it flows from what I have said in [18] above as to submission (1) that there was no longer any scheme or any use to which Credex dollars might be put. I am of the view that they were in effect valueless at all material times.
22 The result of the reasons that I have given is, in my view, that the vendor was unpaid to the extent of $510,000 and that the plaintiff is entitled to enforce a vendor's lien for that amount. Submissions have been put to me by Mr Einstein as to the manner in which that lien may be enforced. I shall say no more of those submissions at the moment, but simply direct that short minutes of order be brought in on Monday 11 December 2006 at 10 am. Any argument as to the appropriateness or form of those orders may take place at that time.
