(ii) Consideration of Murphy v Abi-Saab
39In Murphy v Abi-Saab, the Court of Appeal considered proceedings in which an issue estoppel was held to arise from an order for possession made in favour of a mortgagee, Murphy, with the consent of the mortgagor, Abi-Saab. Murphy v Abi-Saab is instructive so I have quoted this decision at length.
40In Murphy v Abi-Saab, Gleeson CJ (with whom Kirby P and Rolfe AJA agreed) stated at 287 - 289:
"In Rogers v The Queen (1994) 181 CLR 251 at 261, Brennan CJ said that the essence of the doctrine of issue estoppel was defined in the following words of Dixon J in Blair v Curran (at 531):
"A judicial determination directly involving an issue of fact or of law disposes once for all of the issues, so that it cannot afterwards be raised between the same parties or their privies."
... Where there are pleadings, the nature of the resulting estoppels may depend upon choices made by the parties as to what they will plead. (Indeed, this is why the Anshun principle is necessary. In Anshun itself it was the authority's failure to plead its asserted right of indemnity as a defence to Anshun's claim for contribution that meant there was no strict issue estoppel: see 147 CLR 589 at 598.)
In Carl Zeiss Stiftung v Rayner and Keeler Ltd (No 2) [1967] 1 AC 853 at 965, Lord Wilberforce addressed the question how one decides what issues of fact and law are involved in a judicial decision. He said:
"... One way of answering this is to say that any determination is involved in a decision if it is a 'necessary step' to the decision or a 'matter which it was necessary to decide, and which was actually decided, as the groundwork of the decision' ... And from this it follows that it is permissible to look not merely at the records of the judgment relied on, but at the reasons for it, the pleadings, the evidence ... and if necessary other material to show what was the issue decided."
In Blair v Curran (at 532-533), Dixon J said that what is precluded by issue estoppel is what is legally indispensable to the conclusion. In the case of matters of fact, the issue estoppel is confined to the ultimate facts which form the ingredients in the cause of action; facts fundamental to the decision. He said (at 532-533):
"... Where the conclusion is against the existence of a right or claim which in point of law depends upon a number of ingredients or ultimate facts the absence of any one of which would be enough to defeat the claim, the estoppel covers only the actual ground upon which the existence of the right was negatived. But in neither case is the estoppel confined to the final legal conclusion expressed in the judgment, decree or order ..., the judicial determination concludes, not merely as to the point actually decided, but as to a matter which it was necessary to decide and which was actually decided as the groundwork of the decision itself .... Matters cardinal to the latter claim or contention cannot be raised if to raise them is necessarily to assert that the former decision was erroneous."
The difficulty is to distinguish between decisions of fact or law fundamental or cardinal to the judgment and other decisions. One thing, however, is clear. Only a decision about a matter which it was necessary to decide can create an issue estoppel. It is, therefore, essential to approach reasons for judgment which are said to create an estoppel with an accurate understanding of what the author of the reasons was required to decide.
A practical test of whether a decision is fundamental is to ask whether it is possible to appeal against the finding: Spencer Bower and Turner, The Doctrine of Res Judicata, 2nd ed (1969) at 182; Talyancich v Index Developments Ltd [1992] 3 NZLR 28. Since finality of litigation is a primary object of the principle underlying issue estoppel, it would be incongruous if the doctrine operated so as to force a litigant to appeal in order to displace part of the reasoning of a court whilst having no intention, and perhaps no hope, of displacing the judgment: Joseph Lynch Land Co Ltd v Lynch [1995] 1 NZLR 37.
In applying these principles to the present case it is necessary to examine what was at issue in Equity proceedings No 4685 of 1992 before Powell J, and what was fundamental to his reasoning in determining that issue.
The ultimate issue was the mortgagees' right to possession of the land the subject of the declarations and orders claimed.
Upon default by a mortgagor the mortgagee becomes entitled to possession."
41The Chief Justice in Murphy v Abi-Saab continued (at 290 - 192):
"The primary reason given by Powell J for concluding that the mortgagors had no arguable defence to the claims by the mortgagees relating to the possession of land was that an issue estoppel arose out of the earlier Judgment in the Common Law proceedings, supported by the refusal of Newman J to set that Judgment aside Powell J identified the issue estoppel as going to the following matters the existence of a debt owed by the mortgagors to the mortgagees (the quantification of the debt being immaterial), the existence of the mortgages as security, default by the mortgagors.
None of that is inconsistent with the claim for damages or equitable compensation now sought to be raised in the Commercial Division, even assuming that such claim to involve a right of equitable set-off. ...
It has been submitted by Senior Counsel for the Appellants that the finding by Powell J that a debt existed (the mortgagors being estopped from denying the existence of the debt) necessarily involved a finding that there was no defence by way of equitable set-off to claim for the debt.
...
It has been submitted by senior counsel for the appellants that the finding by Powell J that a debt existed (the mortgagors being estopped from denying the existence of the debt) necessarily involved a finding that there was no defence by way of equitable set-off to a claim for the debt.
This submission, however, takes no account of the following matters. Firstly, it is one thing to find that a debt existed, and a different thing to find that the amount of the debt was the amount later claimed in the Commercial Division proceedings. There is more than $8 million involved in the difference. Secondly, where the claim for damages or equitable compensation arguably giving rise to an equitable set-off is, as in the present case, unliquidated, a reference to "the existence of a debt" is not inconsistent with an acknowledgment of the possibility of establishing such a claim. Thirdly, the reasoning of Powell J has to be understood in the context of a mortgagee's claim for possession of mortgaged land, in a situation where there has been a failure by the mortgagors to comply with the covenants for the mortgage, and in particular, those relating to payment of the sum secured.
There was, therefore, no inconsistency between what Powell J said, on 1 October 1992, about proceedings No 4685 of 1992, and what he said, and did, on 8 October 1992, about proceedings No 4650 of 1992.
Similarly, what Powell J went on to say about the alternative or, "Anshun", estoppel arising from the earlier judgment in the Common Law proceedings, needs to be understood in the light of the matters that were in issue before him on 1 October 1992. In relation to proceedings No 4685 of 1992 they were matters relating to the mortgagees' right of possession of the subject land. It is those matters which were before Powell J on 1 October 1992 also in relation to proceedings No 4650 of 1992. In relation to the latter proceedings, it was the notice of motion of the mortgagors seeking to restrain the mortgagees from exercising their rights of possession, and not the entire claim for damages or equitable compensation, which was before Powell J. This, no doubt, is the reason why Powell J perceived no inconsistency between what he said about the "Anshun" estoppel on 1 October 1992 and his refusal to dismiss proceedings No 4650 of 1992 on 8 October. When he was referring to the "Anshun" estoppel, what it was necessary for Powell J to decide was whether the mortgagor's claims for damages or equitable compensation gave rise to a defence to the mortgagees' claim for possession. He expressed what he said as one of his reasons for deciding that issue in favour of the mortgagees. If what he said went beyond that, it was not necessary for his decision.
Bearing in mind the matters that were before him for determination on 1 October 1992, a finding by Powell J that the mortgagors no longer had any claim whatever for damages or equitable compensation against the mortgagees would have gone far beyond what it was necessary, or what it was proper, for Powell J to determine on the occasion.
...
To apply the practical test earlier mentioned, one might ask what the position would have been if, following the decision of 1 October 1992, the mortgagors had sought to appeal but had limited their challenge to the findings made by Powell J about their claim for damages or equitable compensation. Such an appeal would have been hopeless. They would have had no answer to the argument that the mortgagors were entitled to possession of the subject land, and that the declarations and orders made by Powell J were perfectly appropriate. ... An appellate court would not have embarked upon the exercise of deciding the validity of their claim for damages or equitable compensation.
Hunter J was correct to conclude that there is no issue estoppel defeating the defence and cross-claim in the Commercial Division proceedings. The appeal should be dismissed with costs."
42Thus, in Murphy v Abi-Saab, the Court concluded that an issue estoppel arising from a possession order did not extend to preventing the mortgagor from raising cross claims for damages or equitable compensation.
43Mr Bayly concedes that the following matters were treated as necessarily decided by the consent order in the Queensland proceedings, the existence of a debt owed by the mortgagor to the mortgagee; the existence of the Queensland mortgage as security; and default by the mortgagor. To those matters may be added the following: (a) service on the mortgagor of relevant statutory notices and demands; (b) continuing default by the mortgagor after the period specified in those notices; and (c) personal service of the originating application on the mortgagor.
44The plaintiff submitted that the order made in the Queensland proceedings was premised on the propositions that the deed of loan and mortgage are valid and enforceable, and not liable to be impugned or set aside by application of the National Credit Code, statutory unconscionability, or for any other reason and that those matters were necessarily decided by the Queensland order. The plaintiff further submitted that the evidence relied on for possession in the Queensland proceeding is the same evidence that is pleaded and relied on in this proceeding and if Mr Bayly were permitted to plead and rely on his defences and cross-claim based on the National Credit Code and statutory unconscionability, and was ultimately successful on those arguments to defeat the plaintiffs' claim for possession of the NSW properties, there would be a direct inconsistency between the order made in the Queensland proceeding and the orders made in this proceeding.
45In the Queensland proceedings, the ultimate issue was the mortgagee's right to possession of the Queensland land upon default by the mortgagor the mortgagee becomes entitled to possession. The evidence relied on in the Queensland proceedings was limited. I agree that the issue estoppel that arises in these current proceedings go to the following matters, first, the existence of a debt owed by the mortgagor to the mortgagees; second the existence of the Queensland mortgage as security; and finally, default by Mr Bayly in relation to his obligation contained in the loan agreement to make payments.
46In these current proceedings, the plaintiff is not seeking to impugn the order for possession made in the Queensland District Court. After that order was made, the mortgagees sold the Queensland property and the proceeds of sale were applied to reduce the amount Mr Bayly owed under the loan agreement. In my view, the orders that may be made in these proceedings will not be inconsistent with the order made for possession in the Queensland proceedings.
47As a matter that was necessary to decide in earlier proceedings can create an issue estoppel, it was not necessary for the Queensland District Court Judge to determine any right that the mortgagors have to possession to the NSW properties relying on the security of the NSW mortgages. The quantification of the debt was immaterial so it was not necessary to determine the actual amount of money owing (principal and interest) under the loan agreement. Nor was it necessary for the Queensland Court to determine whether Mr Bayly was liable under the guarantee to repay the moneys.
48Mr Bayly in these current proceedings is seeking to challenge his obligation to pay interest at the high rate stipulated in the loan agreement pursuant to certain statutory provisions of the National Credit Code and the Credit (Commonwealth Powers) Act 2010. He is not putting in issue that the mortgagors were not entitled to an order for possession in relation to the Queensland property.
49Applying the practical test referred to in Kuppers and Murphy v Abi-Saab, if Mr Bayly had appealed the decision in the Queensland proceedings, the appellate court would not have embarked on an exercise of examining the interest provisions of the loan, or whether to vary the terms of the loan agreement should be varied particularly so far as interest is concerned, or a claim for statutory compensation, or the existence of the NSW mortgages or the guarantee in order to determine whether the decision was correct. Hence, it is my view that it is far from certain that issue estoppel applies to these proceedings.
