25 I have difficulty in understanding how this extension of the doctrine of privity is relevant to the circumstances which prevail here. In the present case it is the beneficiary of the previous judgment which is said to be in a relationship of privity, not the party against whom the previous judgment was pronounced. Moreover, the extension which was mooted in Carl Zeiss assumes that the losing party in the earlier case does something after judgment has been entered with a view to frustrating the purpose of the judgment.
26 In my opinion there can be no suggestion of privity between the Bank and Mr. Cleary in the circumstances of this case. The issue before the Federal Court, as relevant here, was whether Mr. Jeans was bound by the guarantee. That issue was found against him by reason of his admissions, which he was not permitted to withdraw, that he had signed the document. The case which he was unsuccessfully seeking to put in that Court was that he was not bound by the guarantee because he did not execute it. The identity of the person who forged his signature was irrelevant to that issue. As it happened, it was an officer of the Bank, Mr. Cleary, who purportedly witnessed the signature, and who was therefore alleged to have forged it. But the issue would have been no different if it had been a third party, unrelated to the Bank, who had forged Mr. Jeans' signature. Therefore any employment relationship between the Bank and Mr. Cleary was irrelevant to the fundamental issue which Mr. Jeans was seeking to raise in the Federal Court.
27 Even if this had not been the case, I would have found that there was no privity of interest in the situation which applies here. Mr. Cleary had no relevant interest in the Federal Court proceedings and the Bank has no interest in this case. Accordingly, there is no privity of interest and the doctrine of issue estoppel cannot apply.
Anshun estoppel
28 This form of estoppel arises from the judgment of the High Court in Port of Melbourne Authority v. Anshun Pty. Limited (1981) 147 CLR 589. In that case the Authority was one of two defendants in negligence proceedings brought by an injured worker. Each defendant sought contribution from the other. In fact, the other defendant had previously agreed to indemnify the Authority against claims of this nature. However the Authority made no claim under the indemnity in these proceedings. In due course the worker obtained judgment against both defendants. The Authority was ordered to pay 90% of his damages and the other defendant 10%. Subsequently, the Authority commenced proceedings against the other defendant claiming an indemnity in relation to the amounts it had been ordered to pay to the worker. The trial judge ordered that the action be stayed on the ground that the claim under the indemnity agreement should have been raised in the original proceedings. This was upheld by the High Court.
29 The majority of the court (Gibbs CJ, Mason and Aickin JJ) pointed out that although the judgment which the Authority was seeking to obtain in the second proceedings would contradict the earlier judgment, this was not a case of res judicata or issue estoppel. The causes of action were different, and the question of the indemnity was never raised or addressed in the earlier proceedings.
30 Their Honours went on to discuss whether the case fell within the "extended principle" expressed by Sir James Wigram V.C. in Henderson v. Henderson (1843) 3 Hare at p.115 [67 E.R. at 319]:
"where a given matter becomes the subject of litigation in and of adjudication by, a Court of competent jurisdiction, the Court requires the parties to that litigation to bring forward their whole case, and will not (except under special circumstances) permit the same parties to open the same subject of litigation in respect of matters which might have been brought forward as part of the subject in contest, but which was not brought forward, only because they have, from negligence, inadvertence, or even accident, omitted part of their case. The plea of res judicata applies, except in special cases, not only to points upon which the Court was actually required by the parties to form an opinion and pronounce a judgment, but to every point which properly belonged to the subject of litigation, and which the parties, exercising reasonable diligence, might have brought forward at the time."
31 Their Honours then referred to some of the cases in which the principle enunciated by Wigram V.C. had been affirmed. In certain cases, it had been equated with abuse of process. However their Honours did not regard the abuse of process test as "one of great utility". They preferred a test of unreasonableness:
"In this situation 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 plaintiff's claim and its subject matter, it would be expected that the defendant would raise the defence and thereby enable the relevant issues to be determined in the one proceeding."
