Consideration
10 In Blair v Curran (1939) 62 CLR 464 at 531-533, Dixon J explained how an issue estoppel arises. He said that a judicial determination directly involving an issue of fact or law disposes of that issue once for all so that it cannot afterwards be raised by the same parties or their privies. However, the estoppel covers only those matters which the prior judgment necessarily established as the legal foundation or justification for its conclusion:
The distinction between res judicata and issue-estoppel is that 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.
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 Lord Shaw, "a fact fundamental to the decision arrived at" in the former proceedings and "the legal quality of the fact" must be taken as finally and conclusively established (Hoystead v. Commissioner of Taxation [1926] AC 155).
(emphasis added)
11 As his Honour noted (62 CLR at 533), when seeking to apply those concepts, it is difficult distinguish what is fundamental or cardinal to the prior decision, judgment, decree or order, or necessarily involved as its legal justification or foundation, from other matters, that, although raised and decided as material considerations in the circumstances, are nonetheless not, in point of law, the essential foundation or groundwork of the judgment, decree or order.
12 In Feltham v St Vincent's Hospital (1993) 9 NSWCCR 547 at 570F-571H, Sheller JA, with whom Kirby P (at 549E) and Priestley JA (at 555D) agreed on this issue, applied Blair 62 CLR at 531-533 to the facts there in issue. There, the commissioner in a workers' compensation proceeding had found that the plaintiff had suffered two separate injuries, one to her wrist, the other to her neck and spine, in the one occurrence when her hand became caught in a compactus that she was trying to move. The commissioner found that after the occurrence the plaintiff was, initially, totally incapacitated and, later, partially incapacitated. The employer disputed liability for negligence in the plaintiff's common law proceeding. Sheller JA (at 570F-G) found that the commissioner's findings both as to the wrist and neck injuries "were essential elements in the finding of incapacity". He held that those findings estopped the employer from contending that the occurrence had not caused the injury to the plaintiff's neck and spine.
13 Here, the arbitrator's reasons here were detailed, but they were not judicial reasons. His reasons were those of an administrative decision-maker. They should not be "construed minutely and finely with an eye keenly attuned to the perception of error" or with "unhappy phrasing": see Minister for Immigration and Ethnic Affairs v Wu Shan Liang (1996) 185 CLR 259 at 272 per Brennan CJ, Toohey, McHugh and Gummow JJ. The arbitrator reviewed the evidence, including emails and statements by witnesses, and then considered the submissions of the parties. In particular, he noted the submissions of Ms Leggett's lawyer that argued in support of a finding that real events had occurred and Ms Leggett's perception of those events, and how they affected her, should be determinative.
14 At the commencement of his reasoning on the bullying and harassment issue, the arbitrator identified (at [112]) that the first question for decision was whether, as a matter of fact, the events that Ms Leggett alleged had occurred and, if so, whether those events amounted to bullying and harassment. He added that, next, "one needs to consider whether these events caused or contributed to her psychological injury". The arbitrator proceeded to make findings of fact, which substantively accepted Ms Leggett's account of various instances of Mr Rudolph's conduct toward her, based on both her and his evidence. In the course of making those findings, the arbitrator found that Ms Leggett would have been able to and, in fact, did, perceive Mr Rudolph's conduct in a way that would cause her distress or offence. He noted that, in most instances, Mr Rudolph had sought to refute her allegations. The arbitrator reviewed both Mr Rudolph's evidence and other evidence relied on by the Club. Relevantly, the arbitrator found:
136. In the rest of Mr Rudolph's emails in evidence, he asked a series of questions. The manner in which he asked the questions in some of the emails is of concern, particularly the email sent on 20 September 2016. His reference to the words "If as you say" seems to connote independence regarding new contracts and sponsorships and she had to seek permission. This is consistent with the allegations that she raised in the document in the Reply.
137. The applicant's version of the telephone conversation is supported by the contents of the email that she sent on the date of the incident on 9 October 2016. She complained about being directed to return from the barriers when he had encouraged her to do so on the previous race day. She stated that he was rude and that she did not have the opportunity to explain that she would be back in time before he hung up on her. Therefore, there is contemporaneous evidence to support her description of the events on 9 October 2016. She questioned the tone of Mr Rudolph's voice and why he had spoken so harshly to her. Of course, the authoritative nature of his discussion with the applicant was confirmed by Ms Porteous.
138. In her email, the applicant stated that this event had compounded many other situations in which she had felt down trodden, excluded and questioned unreasonably when carrying out her duties. Therefore, the issues were not confined to the incident on 9 October 2016. Rather than discuss the issue via email, Mr Rudolph requested that the applicant attend a meeting to discuss her work performance without giving any indication as to what needed to be discussed.
139. Therefore, whilst Mr Rudolph has denied many of the applicant's allegations, he has conceded that some of the events did in fact occur and the emails also provide contemporaneous evidence of certain events in support of the applicant's allegations.
(emphasis added)
15 The "document in the Reply" to which the arbitrator referred in [136] was a statement that Ms Leggett had made of complaints about Mr Rudolph's conduct that the Club annexed to its Reply in the arbitration, together with his evidence in response.
16 In his findings of fact at [143], the arbitrator accepted Ms Leggett's evidence that the incidents he had discussed earlier in his reasons (at [112]-[139]) had occurred as she had asserted. That is why he found in [143] that the events she relied on, and which Mr Rudolph and the Club denied had occurred, in fact, and were not imaginary.
17 I am of opinion that the arbitrator's findings at [144] necessarily entailed, having regard to his findings in [143], that not only did the events occur as Ms Leggett described, where they were not otherwise objectively verifiable from documents, but the events also had "the legal quality of the fact" that the way in which Mr Rudolph interacted with her was as she described: Blair 62 CLR at 532 citing Hoystead [1926] AC 155. The finding in [143] is, as the Club argued, a finding that, first, the objective facts occurred and secondly, Ms Leggett perceived those facts and the interactions she had with Mr Rudolph concerning them to be bullying and harassment.
18 Thus, the arbitrator's finding, that there was no reason to doubt the veracity of Ms Leggett's evidence or her perception of those events, created an issue estoppel as to both the occurrence of those events that the arbitrator found at [112]-[139] and his findings as to her perception of what Mr Rudolph did. However, the arbitrator did not decide in [143] that, either, those facts were causative of Ms Leggett's psychological condition or amounted objectively to bullying or harassment.
19 That raises the question as to how [144] in the arbitrator's reasons can be understood. The Club argued that it was, in effect, a summary by the arbitrator of the conclusion he had come to in [143] based on the application of the law to the facts but was, in effect, unhappily expressed. That was because, the Club contended, [144] either omitted a finding that Ms Leggett perceived that she had been exposed to bullying and harassment based on actual facts, so as to give rise to the injury or, alternatively, amounted to no more than a finding that, because she had that perception based on real events, her condition satisfied the statutory definition of an injury, without amounting to an objective finding by the arbitrator that Mr Rudolph's conduct was bullying and harassment.
20 I reject the Club's argument. The real issues between the parties throughout the Workers Compensation Commission proceeding, including the arbitration, were, first, whether the disputed events alleged had occurred at all and, if so, secondly, whether Mr Rudolph's conduct amounted to bullying and harassment. In my opinion, the arbitrator's finding in [144] is of an ultimate fact that went beyond his findings in [143]. This is because the finding in [144] did not amount to a mere restatement of previous findings but addressed the question of fact that the arbitrator had set out at [112]. The finding of actual bullying and harassment in [144] was bound on the facts that the arbitrator had already found in evaluating the events. The characterisation that the arbitrator arrived at in [144] went one step further than his findings in [143], that, first, the events that Ms Leggett described had in fact occurred, contrary to Mr Rudolph's and the Club's case, and secondly, she perceived those interactions as amounting to bullying and harassment. The arbitrator made a further essential finding in [144] that, not only did Ms Leggett perceive Mr Rudolph's conduct as bullying and harassment, but, in fact, it did amount objectively to him bullying and harassing her.
21 In my opinion, it follows that the Club is estopped in this proceeding from denying that Mr Rudolph bullied and harassed Ms Leggett in the respects that the arbitrator found in his reasons at [112] to [144].
22 The second finding which is in issue is whether that bullying and harassment occurred in the course of Ms Leggett's employment with the Club between May and 10 October 2016. In my opinion, that is the ineluctable consequence of the arbitrator's finding in [144], and is reflected in his findings in [162] and [170] that Ms Leggett sustained her psychological injury as an injury arising out, or in the course, of her employment up to 10 October 2016 as a consequence of the events of which she complained. He found that those events were the whole and predominant cause of her injury. Accordingly, the Club is estopped from denying those matters.
