The Settlement Deed and QSC 2019 - issue estoppel and Anshun estoppel
65 The bank relies on QSC 2019 as rendering Mr Davidson's attacks on the Settlement Deed untenable. It says that Ryan J's judgment and her reasons for it give rise to issue estoppel and Anshun estoppel.
66 In Blair v Curran (1939) 62 CLR 464 at 532, Dixon J described issue estoppel as arising when 'a state of fact or law is alleged or denied the existence of which is a matter necessarily decided by the prior judgment, decree or order'. His Honour went on to say:
Nothing but what is legally indispensable to the conclusion is thus finally closed or precluded. In matters of fact the issue estoppel is confined to those ultimate facts which form the ingredients in the cause of action, that is, the title to the right established. 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. In the phraseology of Coleridge J. in R. v. Inhabitants of the Township of Hartington Middle Quarter [(1855) 119 ER 288 at 293], 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, though not then directly the point at issue. 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.
67 In QSC 2019 the point directly at issue was whether the bank was entitled to enforce its mortgage over the Heidke Road property. Ryan J's conclusion that it was necessarily entails a conclusion that the mortgages were valid and enforceable. To the extent that Mr Davidson claims to the contrary now, he necessarily claims that QSC 2019 is erroneous. He is estopped from doing so. That is why Derrington J dismissed his application for an injunction restraining the enforcement of certain mortgages in FCA 2020.
68 In QSC 2019 Ryan J also decided, as part of the groundwork for her decision, that Mr Davidson had no real prospects of establishing that the releases he gave were voidable because of economic duress. While her Honour's judgment was in form to grant an application by the bank, it was also in substance a decision to dismiss a countervailing attack on the releases which Mr Davidson mounted on the basis of economic duress. That engages the principle from Blair v Curran, to the effect that the estoppel only covers the actual ground upon which the existence of the legal right was negatived. In QSC 2019 the legal right asserted was the right to set aside the Settlement Deed and the actual ground on which it was negatived was that there was no duress, or if there was it did not cause Mr Davidson to sign the Settlement Deed. So the relevant issue estoppel is against asserting economic duress.
69 That assertion is the foundation of claim (7), that Mr Davidson signed the Settlement Deed because he was being threatened with the appointment of receivers. QSC 2019 means that claim is untenable. Ryan J directly considered this allegation, and for a court to find that the appointment of the receivers placed him in a situation where he had no choice but to sign the Settlement Deed would be to imply that QSC 2019 is wrong.
70 The bank's reliance on QSC 2019 went further than this. In this court it submitted that Ryan J's determination necessarily decided the issue of the enforceability of the releases. If that is correct, then claim (6), which is to the effect that the Settlement Deed is liable to be set aside because it was induced by misleading or deceptive conduct, would entail a conclusion that her Honour's decision was wrong. But I do not accept the bank's submission in that regard. In my view, the principles laid down in Blair v Curran apply, as I have indicated, only to preclude re-agitation of the actual ground upon which Ryan J negatived Mr Davidson's claim that the deed was voidable. That ground was economic duress, not misleading conduct.
71 Contrary to a submission by the bank, I do not consider that in FCA 2020, Derrington J reached the conclusion that QSC 2019 gave rise to an issue estoppel against any attack on the enforceability of the releases. While at [25] his Honour did include the validity of the Settlement Deed among a list of things that were 'the essential and necessary determinant in Ryan J's reasons', it is clear from the same paragraph that the actual basis of his Honour's decision was that QSC 2019 has 'determined the validity of the mortgage and the Bank's entitlement to enforce its security'. As will be seen, his Honour had already considered the validity of the releases separately, and I do not consider that he applied any issue estoppel to that question.
72 That is all academic, however, because I do accept the bank's further submission that the principles of Anshun estoppel stand in the way of Mr Davidson's attempt to impugn the Settlement Deed for misleading or deceptive conduct. An estoppel of that kind 'will preclude the assertion of a claim or of an issue of law or fact if the claim or issue was so connected to the subject matter of the first proceeding as to make it unreasonable, in the context of the first proceeding, for the claim or issue not to have been made or raised in it': Timbercorp Finance Pty Ltd (in liq) v Collins [2016] HCA 44; (2016) 259 CLR 212 at [27] (French CJ, Kiefel, Keane and Nettle JJ). While, in QSC 2019 Mr Davidson did not submit that the Settlement Deed should be set aside on the basis of misleading or deceptive conduct, the evidence he gave and the submissions he did make required Ryan J to consider his reasons for signing the deed in detail, and her Honour did so. The proceeding was, in effect, a full trial about why he entered into the Settlement Deed. Mr Davidson had raised that question, from the point of view of duress, in order to resist an order which would have had the drastic consequence that he would be evicted from his home. He was represented by solicitors and counsel and he must have known, or should be taken to have known, that if there was any basis open for impugning the Settlement Deed, it needed to be raised before Ryan J. If a claim based on misleading or deceptive conduct was open to be made, it was unreasonable of Mr Davidson not to have done so before Ryan J.
73 I accept that this was a ground of Derrington J's decision in FCA 2020. As I have indicated, his Honour did deal specifically with the validity of the Settlement Deed. He found (at [23]) that:
any claim relating to the validity of the releases could have, and should have, been agitated in the proceedings in the Supreme Court of Queensland. That being so, the applicants are estopped from commencing or prosecuting any further claim in this regard, the validity of the releases having been settled by action.
That is a conclusion which his Honour reached in the course of making an order dismissing Mr Davidson's application for an injunction against the bank in this proceeding. It would be extraordinary for a judge in the same proceeding to differ from that conclusion unless error had been conclusively shown. But there is no need for me to differ here, as I respectfully agree with Derrington J.
74 Mr Davidson nevertheless seeks to avoid the effect of the judgment of the Supreme Court of Queensland in QSC 2019 by alleging that it was obtained by arguments 'based on a fraud'. The fraud appears to be the allegedly forged withdrawal authorisations. This is misconceived. The issue in QSC 2019 was whether Mr Davidson had real prospects of having the Settlement Deed set aside. Only then could he pursue his allegations of fraud. Ryan J's judgment was not in any sense based on any finding that Mr Houlihan's alleged frauds did not occur. It was solely concerned with the circumstances in which the Settlement Deed (and Heads of Agreement) came to be executed.
75 Mr Davidson also seeks to impugn QSC 2019 on the basis that Ryan J did not consider his argument based on the Land Title Act 1994 (Qld). But this too is misconceived. The obvious reason why the court did not consider that argument is because Mr Davidson (advised and represented by solicitors and counsel) did not make the argument. That provides no basis to find, as Mr Davidson submitted, that QSC 2019 is unsafe.
76 Mr Davidson also made allegations in submissions that evidence of at least one bank officer which was put before Ryan J was 'perjury'. This was an example of a propensity Mr Davidson has displayed throughout this proceeding to make scandalous allegations, quite casually, without any attempt to refer to specific evidence that is reasonably capable of establishing them. The fact that he is not a lawyer with professional obligations not to make such allegations does not make it appropriate.
77 Mr Davidson submitted that by directing her Honour's attention to the question of the economic duress claim, the Supreme Court became 'misdirected' away from 'Houlihan's fraud and forgeries and theft'. The response to that which immediately occurs to one is that it was Mr Davidson through his lawyers who raised the claim of duress: see QSC 2019 at [3]. In any case, it was not a misdirection. Determining whether there were reasonable prospects of the avoidance of the release was an essential threshold issue to determine in the proceedings before Ryan J.
78 Mr Davidson also submits that the issue estoppel is being used 'to suppress evidence of Suncorp's fraudulent misdeeds'. He says that the judgment was based on limited information that he had and that Suncorp chose to put before the courts, and not on a complete investigation of the documents he now seeks. Once again, Mr Davidson had legal representation and the issues which were agitated (and not agitated) must be taken to reflect forensic choices made on his behalf. Any asserted gap in the evidence put before the Supreme Court of Queensland is no basis to disregard the judgment of that court, and neither it, nor any of the other matters Mr Davidson has raised, would give this court any power to overturn that judgment.
