…we would prefer to say that there will be no estoppel unless it appears that the matter relied upon as a defence in the second action was so relevant to the subject matter of the first action that it would have been unreasonable not to rely on it. Generally speaking, it would be unreasonable not to plead a defence if, having regard to the nature of the plaintiff's claim and its subject matter it would be expected that the defendant would raise the defence thereby enable the relevant issues to be determined in the one proceeding.
…"
23 Their Honours continued:
"The Authority did not adduce evidence at the trial to show why it failed to raise the indemnity issue in the first action. Apart from considerations such as the ability to overcome any prejudice to Anshun by orders for costs and the fact that O'Bryan J refused to strike out the action summarily - matters mainly associated with the conduct of this action - the Authority's case is that the principle in Henderson v Henderson (1843) 3 Hare 100 [67 ER 313] does not apply.
There is, however, one other factor which should be mentioned. It is that the defence of an indemnity required to be specially pleaded at common law. It was not covered by a general or particular traverse. Consequently the failure to plead it would not have founded an estoppel under the old law in its strictest formulation. But the evolutionary development of that rule evidence by the decision in Humphries v Humphries (1910) 2 KB 531 may well have resulted in releases and indemnities being equated to traversable allegations for the purposes of estoppel. In any event the fact that the defence required to be specially pleaded at common law is not now a material consideration. It does not derogate from the conclusion that it was unreasonable for the Authority to refrain from raising its case of indemnity for disposition in the first action."
24 There has been no evidence adduced at this hearing to explain why Huxley and the Wilkinsons did not raise the variation of the agreement issue at the arbitration.
25 At [58] of the arbitral award the arbitrator found that Leveraged Equities was entitled, under the terms of the written agreement, to demand payment from the claimants. As previously stated, the arbitral award was final and binding and the awards have been entered as judgments of this Court.
26 Counsel for Leveraged Equities submitted that the finding in [58] of the arbitral award was 'legally indispensable to the conclusion' reached by the arbitrator. In Blair & Perpetual Trustee v Curran (1939) 62 CLR 464 at 532 Dixon J stated,
"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."
27 In Port Melbourne Authority v Anshun the High Court explained:
"The distinction between res judicata (in England called 'cause of action estoppel') and issue estoppel was expressed by Dixon J in Blair v Curran [(1939) 62 CLR 464, at 532] in these terms:
'in the first the very right or cause of action claimed or put in suit has in the former proceedings passed into judgment, so that it is merged and has no longer an independent existence, while in the second, for the purpose of some other claim or cause of action, 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.'
The distinction was restated by Fullagar J in his dissenting judgment in Jackson v Goldsmith (1950) 81 CLR 446, at 466. His Honour expressed the rule as to res judicata by saying: 'where an action has been brought and judgment has been entered in that action, no other proceedings can thereafter be maintained on the same cause of action. This rule is not, to my mind, correctly classified under the heading of estoppel at all. It is a broad rule of public policy based on the principles expressed in the maxims " interest reipublicae ut sit finis litium " and " nemo debet bis vexari pro eadem causa ".' His Honour went on to discuss issue estoppel, citing the comment of Dixon J in Blair v Curran: 'A judicial determination directly involving an issue of fact or of law disposes once for all of the issue, so that it cannot afterwards be raised between the same parties or their privies.'"
28 According to counsel for Leveraged Equities, following Blair v Curran, if the cross-claimants' cross claims were successful, that would be 'necessarily to assert that the [arbitrator's] decision was erroneous'.
29 Huxley and the Wilkinsons' allege in their cross claims that there was a variation to the written agreement. The agreement, provided that Leveraged Equities would not demand repayment of the loan, which it had provided for a term of 12 months. The cross claims are based on a cause of action said to arise out of an alleged breach of that term. The purported oral variation to the agreement was, in my view, so closely connected with that claim that it was unreasonable not to raise it in the earlier proceedings. In my view the Wilkinsons are estopped from raising this issue in these current proceedings.
30 It does not matter that the claims that underpin this litigation were determined by way of arbitration. This is consistent with the policy that there should be finality in litigation. Arbitral awards can give rise to estoppels: see Onerati v Phillips Construction Pty Ltd (1989) 16 NSWLR 730, 739 per Giles J; and more recently Nicholls v Michael Wilson & Partners Limited [2010] NSWCA 222 at [103] and [399].
31 Counsel for Leveraged also submitted that the considerations outlined by Handley JA (with whom Mason P and Heydon JA agreed) in Rippon v Chilcotin Pty Ltd (2001) 53 NSWLR 198, 204 at [32] may be of some assistance in determining whether to strike out the cross claims. These considerations are set out in State Bank of New South Wales Limited v Stenhouse Ltd (1997) Aust Torts Reports 81-423 (64,077) at 64,089 where Giles CJ Comm D (as he then was) said:
"…The guiding considerations are oppression and unfairness to the other party to the litigation and concern for the integrity of the system of administration of justice, and amongst the matters to which regard may be had are -
(a) the importance of the issue in and to the earlier proceedings, including whether it is an evidentiary issue or ultimate issue;
(b) the opportunity available and taken to fully litigate the issue;
(c) the terms and finality of the finding as to the issue;
(d) the identity between the relevant issues in the two proceedings;
(e) any plea of fresh evidence and the reason why it was not part of the earlier proceedings; …
(f) the extent of the oppression and unfairness to the other party if the issue is relitigated and the impact of the relitigation upon confidence in the administration of justice; and
(g) an overall balancing of justice to the alleged abuser against the matters supportive of abuse of process."
32 These considerations as approved by the Court of Appeal in Rippon v Chilcotin at [33], "turn on a precise identification of the issues".
33 Most of those considerations have already been dealt with above. Further considerations relate to evidence. The cross-claimants have not provided any evidence relating to the issue in their cross-claims (despite many chances to do so, both during the arbitration process and in this Court), nor have they provided any evidence as to why that issue (or evidence relating to it) was not raised at the arbitration (again, despite numerous chances to do so). So far as unfairness is concerned, Leveraged Equities has already been put to the cost of the arbitration proceedings, two Supreme Court proceedings and one appeal. It would be unfair to allow Huxley and the Wilkinsons to relitigate the same subject matter again.
34 Counsel for Leveraged Equities also referred to Finance & Equity v Leveraged Equities [2007] NSWSC 886 at [26] where Hammerschlag J. In that case Hammerschlag J referred to an oral conversation between Mr Huxley and Mr Mackellar. His Honour then considered the argument which Huxley and the Wilkinsons sought to raise to be 'illusory'.
35 At [22] to [25] Hammerschlag J stated:
"22 The affidavit material establishes that before the Loan was entered into, Mr Huxley had conversations with a Mr MacKellar, a stock broker with Bell Potter Securities Ltd whose knowledge I shall assume for the purposes of this judgment is to be attributed to the defendant. He also had a conversation with Mr Shane Butler, the Business Development Manager employed by the defendant.
