As the last citation makes clear the rule is a rule of practice. It does not mean that the person liable on the bill but claiming to have an unliquidated claim against the holder of the bill is left with no remedy at all. It means merely that, the claim must be litigated elsewhere, except in exceptional cases.
The rule has been applied in Australia on many occasions. Indeed my researches suggest that only in Ingleton v Coates (1896) 2 ALR 154 was a different approach taken. Aickin J referred to the decision of the House of Lords in Nova (Jersey) Knit Ltd with apparent approval in KD Morris & Sons Pty Ltd (In liquidation) v Bank of Queensland Ltd (1979-80) 146 CLR 165 at 203, although it must be said that his Honour was in the minority in that case, albeit not in respect of any matter for which the House of Lords decision is authority. The rule has been accepted as applicable in Australia in a multitude of cases. These include in Victoria, Mobil Oil Australia Ltd v Caulfield Tyre Service Pty Ltd [1984] VR 440, a decision of the full Supreme Court and Pinewood Resources Ltd v Moffat (Tadgell J, 5 April 1989, unreported) in New South Wales in Buying Systems (Aust) Pty Ltd v Tien Mah Litho Printing Co (PTE) Ltd (1986) 5 NSWLR 317 at 327-8 per Cohen J, Ferro Corporation (Aust) Pty Ltd v International Pools Aust Pty Ltd (1993) 30 NSWLR 539, per Rolfe J, and Coloursplendor Graphics Ltd v FMF Colour Creations Pty Ltd (unreported, Brownie J, 3 December 1987); in Western Australia in Amalta Holdings Pty Ltd v Richard Geoffrey Luff (unreported, Full Court, Kennedy, Franklyn and Seaman JJ, 21 December 1989); in Queensland in Eversure Textiles Manufacturing Co Ltd v Webb [1978] QR 347 and in New Zealand in International Ore and Fertilizer Corporation v East Coast Fertilizer Co Ltd [1987] 1 NZLR 9, and Finch Motors Ltd v Quin [1980] 2 NZLR 513.
One of the exceptions to the rule, as is made clear in the judgment of Lord Salmon in Nova (Knit) is the case of fraud. There are three possible explanations for this. The first is to be found in s34(3) of the Bills of Exchange Act (1909) (Cth) which sets out the circumstances where the title of a person who negotiates a bill may be defective. Those circumstances include fraud as well as where the bill has been obtained by unlawful means. The second is that a Court of Equity could set aside the bill if obtained by fraud, so that it is necessary to deal with the case in fraud before permitting judgment to be entered for the face value of the bill. The third is that it would be unconscionable in a case where the bill was obtained by fraud to permit the fraudulent party to rely on the bill without permitting the party liable on that bill to raise the liability of the holder of the bill in damages or to an account by way of a cross-claim. By analogy, therefore the rule would have no application in a case where by virtue of some statutory provision the Court might set aside the bill. Such a case would arise where there has been conduct in breach of s52 of the Trade Practices Act in circumstances where s87 of that Act could be invoked to set aside the bill cf Ferro Corporation (supra at 541-2). Likewise, where the bill was obtained as a result of conduct which was misleading and deceptive in breach of s52 of the Trade Practices Act it may well be that the rule has no application. That, however, is not a matter which is required to be determined in this case.
It does not follow from the rule or its underlying rationale, that a claim, as alleged on behalf of Shearer, could not constitute an "off-setting claim" as that expression is defined in s459H. All that follows from the rule (subject to any exception relevant to cases where s52 has been breached) is that if Shearer were sued by Gehl and sought to set up a cross-claim or cross-demand for an unliquidated amount based either upon s52 of the Trade Practices Act or a claim for breach of an implied term, a court would not stay judgment on the proceedings to recover moneys owing under the bills until the hearing of any cross-claim or cross-demand. Summary judgment would be ordered upon proof of the bills, no stay of execution would be granted and the cross-claim or cross-demand would proceed for hearing in due course. But to say that is not to say that Shearer has no cross-demand.
The word "cross-demand" is a word of considerable width. While the words "counterclaim" and "set-off" are technical words, the meanings of which are confined, the same is not true of the word "cross-demand". That is not a technical term. Thus in In re A Bankruptcy Notice [1934] 1 Ch 431, Lord Hanworth MR, after discussing the technical meaning of the words "counterclaim" and "set-off" in the context of bankruptcy legislation, said (at 438):
"I turn, therefore, to what to my mind is the wider word, cross-demand'. If a cross-demand is only to be interpreted as meaning something which could have been introduced into the action by way of counterclaim, it adds nothing to the word counterclaim'. Cross-demand' seems to me to be a word introduced in order to give a wider ambit to the meaning of these claims, something that would not be described, certainly, as a set-off, something that could not have been brought in the action, something that still lies outside a counterclaim, but is of a nature which can be specified and which is of such a nature that it equals or exceeds the amount of the judgment debt. I do not desire to say what cross-demand' may include, but it is not difficult to say that it does not include a claim of such uncertain nature as appears in these Chancery proceedings."
