The primary judge's reasons
20 The primary judge's reasons were extensive, comprising 273 pages, structured in an orderly way, identifying first the issues arising from the pleadings (at J[3]-[24]), the legislative context (at J[25]), and summarising Ms Edgar's evidence and that of her witnesses, with respect to the key events and for the purposes of relief (at J[26]-[269]) and then NRFA Services' evidence in a similar fashion (at J[270]-[603]). Then, under the primary heading "Consideration", the primary judge described Ms Edgar's case as being capable of being separated into two parts - the first concerning her allegations of discriminatory behaviour on the part of Mr Boxsell in 2017 and on 14 February 2018, and the second concerning her allegations that she was suspended, disparaged, threatened with disciplinary action and dismissed because on 11 August 2017 and in 2018 she complained about that behaviour and other conduct (at J[604]), thereafter describing each of those parts in further detail (at J[605]-[616]).
21 Relevantly, the primary judge understood (consistent with how Ms Edgar had formulated her allegations) that:
611 Ms Edgar contended that by 6 February 2018, Mr Melzer and Ms O'Reilly had determined to get rid of her because she had complained, a contention said to be supported by the fact that a recruiter was briefed that day. Ms Edgar asserted that the matters later raised at the Midyear Review as shortcomings "were clearly unfair, unreasonable [and] designed to create a paper trail for performance management" and to put pressure on her to resign. Ms Edgar argued that the Human Resources department had been influenced (against her interests) by Mr Boxsell, Mr Melzer and Ms O'Reilly. She contended that from February 2018, Mr Boxsell, Mr Melzer and Ms O'Reilly asserted that she was a poor performer when in fact her performance had been satisfactory. That negative assessment was said to have been accepted without question by the Human Resources department and, despite Ms Edgar's Third Complaint on 20 February 2018 which was focussed on Mr Boxsell's behaviour towards her, it directed all its "assistance" towards the informal resolution of the matter by reference only to her performance. Ms Edgar described her interactions with Ms Williams and Ms Wetherall as dominated by dismissiveness, disbelief, lack of support or interest, curtness, impatience and deference to Mr Boxsell.
612 Ms Edgar contended that even though she had not yet made her complaint about Mr Melzer, his 5 March 2018 threat of disciplinary action was motivated by the knowledge that she was going to make a complaint. That conversation followed Mr Cross, Ms Wetherall, Ms Williams and Mr Melzer's discussion at 4:00pm that day about her potential complaint, the notes of which included the phrases "finesse her out the door", "point of departure" and "getting her out the door". A "concerted conspiracy" was expressly not contended but it was submitted nonetheless that what occurred was to some extent "a shared enterprise" in that:
… Mr Melzer, Ms O'Reilly and Mr Boxsell and Mr Cross all took the view, for reasons some of which might have been shared and some of which perhaps were not, that the investigation was the means by which they could bring about the termination of Ms Edgar … [and] each participated in the process in such a way as to make sure no other outcome was possible.
613 It was submitted that Mr Boxsell and Mr Melzer had also let Mr Cross know their view that Ms Edgar was a poor performer and, even before he commenced his investigation, persuaded him that there was no proper basis for her complaint. Not long after, it was contended, Mr Melzer disparaged Ms Edgar by telling her co-workers that she had been suspended because she had made disparaging remarks, was inattentive and performing poorly at work.
614 Ms Edgar submitted that Mr Cross's investigation was solely aimed at bringing about her dismissal. She advanced the following contentions in support of that argument:
(a) Mr Cross made clear and unequivocal statements at the commencement of the investigation that her complaints were "groundless";
(b) Mr Cross put legal review of his actions beyond reach when he destroyed evidence;
(c) Mr Cross's findings reversed well accepted principles that contemporaneous written evidence is to be preferred over later oral evidence;
(d) Mr Cross failed to investigate all the matters the subject of complaint; and
(e) it was not open to Mr Cross to find that she wrote emails exaggerating or seeking sympathy, given she denied exaggerating or seeking sympathy.
615 Other matters supporting a conclusion that Mr Cross's investigation was designed to lead to Ms Edgar's dismissal were said to be:
(a) no one ever met with Ms Edgar to assist her to properly identify the nature and extent of her complaints, as was required under NSFA Services' policies, which were never referred to in the investigation;
(b) Mr Boxsell and Mr Melzer either lied or misled Mr Cross on matters ranging from Ms Edgar's performance to whether they had engaged in the conduct alleged against them;
(c) Mr Boxsell and Mr Melzer's conduct in engaging with the Human Resources department and with Mr Cross during the investigation was motivated by Ms Edgar's complaints;
(d) Mr Boxsell, Mr Melzer, Mr Cross and Ms O'Rourke were each essential participants in the decision making;
(e) Ms O'Rourke relied entirely upon Mr Cross's reasoning and accepted without question or further consideration his findings and recommendations concerning Ms Edgar to recommend to Mr Spanner that she be dismissed; and
(f) Mr Spanner accepted Ms O'Rourke and Mr Cross's recommendations without question or further consideration.
616 Ms Edgar pleaded that the suspension, disparagement and threat of disciplinary action and the dismissal were adverse action in that the suspension and disparagement altered her position to her prejudice, the threat of disciplinary action threatened unparticularised adverse action and the dismissal was a dismissal. The conduct was said to have been motivated by reasons prohibited by the FW Act, namely by the fact that she had made complaints about the conduct of Mr Boxsell and Mr Melzer, each of which said to have been an exercise of the workplace right, protected by the FW Act, to make a complaint or enquiry in relation to one's employment
(Footnotes omitted.)
22 What is apparent from this summary of Ms Edgar's claim, about which no issue was taken on appeal, is that the alleged conduct of Mr Cross, Mr Boxsell and Mr Melzer giving rise to her claim of a "shared enterprise" arises from the identified specific allegations against each of them.
23 The primary judge then expressed, in summary form, his view as to the credibility of witnesses, being that "the accounts of the respondents' witnesses are to be preferred over those of Ms Edgar and her witnesses", for the reasons which are thereafter set out: at J[617]. The primary judge then, immediately thereafter, proffers part of his reasoning for why he preferred the accounts of the respondents' witnesses: His Honour lacked confidence, at times, that Ms Edgar was "an accurate historian or that she came away from the exchanges she described with a correct understanding of what had been discussed, determined or agreed": at J[618]. His Honour then gave illustrations from the evidence of where it was evident from Ms Edgar's lack of attention or inability to comprehend uncomplicated concepts that she misunderstood, misapprehended or misremembered numerous interactions with her work colleagues: For example, without being exhaustive, at J[619]-[625], [627], [640], [650], [653]-[654].
24 The primary judge then makes findings of fact in relation to critical events giving rise to the purported offending conduct. On each occasion, without exception, he prefers the evidence of the respondents' witnesses over that of Ms Edgar. None of these findings are the subject of appeal. These findings underpinned the primary judge's ultimate findings which are the subject of this appeal, namely that the primary judge did not accept that Mr Cross was a decision-maker and found that NRFA Services discharged its onus.
25 Ms Edgar's focus on appeal is the portion of the primary judge's deliberations, at the end of the judgment, where his Honour makes ultimate findings as to who made the decision to dismiss (at J[780]-[784]) and the reasons for dismissal (at J[785]-[791]). However, it is necessary to consider the multifarious subsidiary findings which precede and give rise to these ultimate findings.
26 Under the heading "Who made the decision to dismiss?", at J[780], the primary judge, accepting that Ms Edgar was able to allege individual participants in this decision to dismiss (without pleading the same), identified a "preliminary issue", namely the "participants" in the decision to dismiss, as being not only Ms O'Rourke and Mr Spanner, but also Messrs Boxsell, Metzer and Cross: at J[780]. His Honour stated (extracting a portion of Ms Edgar's closing submission):
780 …In substance, Ms Edgar's argument was that Messers Boxsell, Melzer and Cross were part of the decision-making process rather than simply part of the investigation process, She argued that all of Mr Cross's:
… decisions as to the conduct of the investigation, the credibility of witnesses, and the recommendations he delivered were part and parcel of the decision making chain that resulted in Ms Edgar's termination. So to [sic], were the decisions made by Mr Boxsell and Mr Melzer as to what information to provide Mr Cross.
Messrs Boxsell, Melzer and Cross's involvement in the ultimate decision to terminate Ms Edgar was critical. Each applied their own reasoning process:
a. Mr Boxsell's was to provide Mr Cross with a series of denials concerning the conduct alleged against him by Ms Edgar. This was done in order to deflect the focus of Mr Cross's enquiry away towards Ms Edgar. He did so for reasons that included Ms Edgar's complaints about him.
b. The same can be said of Mr Melzer.
c. Mr Cross chose to accept the evidence of Mr Boxsell and Mr Melzer. … He had an interest in upholding the denials of Ms Edgar's allegations - in doing so he protected senior staff, and (initially) minimised the risk that Norton Rose would be obliged to remedy (including monetarily) Ms Edgar for Mr Boxsell's and Mr Melzer's wrongful conduct. It can be readily inferred that Mr Cross's reasons for doing so included the fact that Ms Edgar had made a formal complaint, and that he wished to shut such a complaint down before the firm was exposed to a significant risk.
781 Ms Edgar submitted that Ms O'Rourke simply relied upon Mr Cross (and necessarily, Mr Boxsell and Mr Melzer) to form the view that she should be dismissed as a consequence of her complaints, and Mr Spanner in turn relied upon Ms O'Rourke.
782 Although Mr Spanner presumably considered the merits of Ms O'Rourke's recommendation that Ms Edgar be dismissed before authorising her to take that step, the evidence indicates that, of the two of them, the substantive decision-maker was Ms O'Rourke and that whatever views she had reached concerning Ms Edgar were accepted, and in substance adopted, by Mr Spanner. Consequently, Mr Spanner's role need not be considered further.

27 It may be observed from the extract of Ms Edgar's closing submissions contained in the primary judge's reasons that a central element to Ms Edgar's thesis against Mr Cross was his choice in accepting the evidence of Mr Boxsell and Mr Melzer as to their "denials" of Ms Edgar's allegations against them.
28 It may be remembered that Mr Cross was charged with investigating Ms Edgar's complaints about Mr Boxsell's and Mr Melzer's conduct towards her. Mr Cross found that her complaints were unsubstantiated. At hearing, both sides put on evidence about the circumstances giving rise to Ms Edgar's allegations. The primary judge described, in a detailed way, the evidence of Ms Edgar, Mr Melzer and Mr Boxsell with respect to each of Ms Edgar's allegations forming her complaint. Ultimately, the primary judge found, in essence, that he accepted their testimony over Ms Edgar's. By way of illustration, his Honour preferred the accounts of the respondents' witnesses over Ms Edgar in conversations or meetings, on ten occasions, between 14 February and 21 March 2018 (including preferring the evidence of Mr Boxsell, Mr Melzer and Mr Cross over Ms Edgar): at J[623]-[675]. The primary judge also made specific findings against her in relation to certain of her allegations against each of them. Without being exhaustive, the primary judge specifically rejected the majority of the 2017 allegations made by Ms Edgar which formed part of her complaint concerning Mr Boxsell (which were also relied upon by her as part of her general protections claim on the basis of her sex) and made the following findings:
725 The conclusions I expressed earlier in these reasons concerning Ms Edgar's evidence regarding events in 2018, including my preference for the recollections of Mr Boxsell and Ms O'Reilly concerning the Mid-year Review to those of Ms Edgar, have relevance for how the Court should treat her evidence of the conversations in the period March 2017 to November 2017. That evidence is contradicted by the evidence of Mr Boxsell and lacks corroboration by other witnesses. I also note that Mr Pratap did not agree with Ms Edgar's version of their August 2017 conversation and gave cogent reasons for that lack of concurrence.
726 In circumstances where I have concluded that Ms Edgar has misunderstood or misremembered what was said to her on other occasions important to this case and was generally not a reliable historian, I am not persuaded that her uncorroborated accounts of statements she says were made by Mr Boxsell in 2017 should be preferred over his versions of those interactions. I do not overlook the fact that Ms Edgar had set out her versions of events in documents that were created close to the time various events are said to have occurred but those documents are only as reliable as Ms Edgar's original understanding and recollection of what was said and I am not persuaded that her understanding and recollection are reliable. As I said earlier, I have reached the conclusion in this case that the accounts of the respondents' witnesses are to be preferred over Ms Edgar's.
29 Ms Edgar had alleged that Mr Boxsell had behaved inappropriately during the Mid-Year Review on 14 February 2018. The primary judge preferred the evidence of Mr Boxsell and Ms O'Reilly as to what occurred over Ms Edgar: at J[624]. In relation to a meeting on 5 March 2018, the primary judge preferred the evidence of Mr Melzer, where he denied making a threat and demanding Ms Edgar apologise to Mr Boxsell for disparaging him: at J[667]. The primary judge rejected Ms Edgar's claims that Mr Melzer had sought to replace Ms Edgar in early 2018 (at J[687]):
687 The second submission concerning Mr Melzer's credit referred to the fact that he had contacted a recruitment agency in early February 2018, which was said to show that "he had already commenced on a course of conduct aimed at replacing Ms Edgar". The argument seemed to be that the fact of that contact, and the inference Ms Edgar drew from it, was evidence supportive of the contention that Mr Melzer had lied about her November 2017 instant messenger exchange with Ms Panoiu and that it all pointed to him wanting to replace her. I do not agree that the conclusion propounded can safely be drawn from the thin material cited. In particular, the contention that there was a course of conduct aimed at replacing Ms Edgar is only unsupported supposition. It is contradicted by Mr Melzer's evidence that in early February 2018 he wanted a staffing contingency plan because he was concerned that Ms Edgar might leave before the MAP was completed which was essentially corroborated by Ms O'Reilly, who said that at that time they thought Ms Edgar would resign because she did not seem happy in her role. I reject the inferences Ms Edgar draws from the fact that recruiters were approached in February 2018 and accept that Mr Melzer was not seeking to replace her.

30 Accordingly, when the primary judge came to deciding the question of "Who made the decision to dismiss?", he did so in a context where he had already made substantial findings of fact in each of the purported decision-makers' favour over Ms Edgar and had made no adverse findings against them.
31 Further, his Honour had already made a number of specific factual findings concerning Mr Cross's evidence, rejecting Ms Edgar's submission as to his pre-determination of the outcome and him being actuated by a prohibited reason. First, his Honour accepted Mr Cross's account of the meeting with Ms Edgar during the investigation: at J[675]. Secondly, his Honour rejected the main bases of attack arising during Mr Cross's cross-examination regarding whether Mr Cross was providing legal advice prior to his engagement as the investigator: at J[706]-[709]. Thirdly, his Honour dismissed Ms Edgar's argument that Mr Cross had engaged with the merits of the issue before investigating it and expressly rejected the allegation of his prejudgment of the outcome before investigation: at J[710]. Fourthly, his Honour did not accept that Mr Cross had changed his evidence regarding his investigation's treatment of emails: at J[711]-[713]. Fifthly, his Honour rejected Ms Edgar's allegation of pre-determination based on the fact that Mr Cross did not interview Ms Edgar as "a first step", accepting Mr Cross's reasoning: at J[714]. Sixthly, his Honour rejected Ms Edgar's claim, again purportedly about pre-determination, that Mr Cross had ignored part of her complaint: at J[715]. Seventhly, his Honour rejected Ms Edgar's claim that any negative inference could be drawn from the fact that Mr Cross had destroyed his handwritten investigation notes after they had been incorporated into his report: at J[716]-[718].
32 As part of his Honour's consideration of this last attack on Mr Cross's credibility regarding the handwritten notes, his Honour found, at J[716]:
…Those criticisms are part of the wider contention that the outcome of Mr Cross's investigation was pre-determined, which I do not accept. Not accepting that contention, I also do not accept that Mr Cross was motivated to destroy his handwritten notes to conceal a fixing of his investigation.
33 This finding is consistent with the earlier findings made by the primary judge where he did not accept that Mr Cross had pre-determined the outcome and provides the crucial decisional backdrop to his Honour's consideration later in the judgment regarding who made the decision to dismiss. Given his Honour was satisfied that Mr Cross was not actuated by a prohibited reason, then whether he was a decision-maker or not became immaterial.
34 It is appropriate then for there to be a return of focus to the portion of the primary judge's reasons which deals with the decision to dismiss.
35 The primary judge found that whether an adverse action was the product of the reasoning of more than one person was a factual question that depends on the circumstances of each case, which is entirely correct: Gibbs v Palmerston Town Council (unreported, Gray J, 21 December 1987) at 85-6 (citing Wood v Lord Mayor, Councillors & Citizens of the City of Melbourne (1979) 41 FLR 1 at 19-20); Wong v National Australia Bank Ltd [2022] FCAFC 155; 318 IR 148 at [25], [78]. Accordingly, at J[783] his Honour correctly countenanced the idea that adverse action could be the product of more than actor, and more than one decision-maker, citing Gibbs and Construction, Forestry, Mining and Energy Union v Clermont Coal Pty Ltd [2015] FCA 1014; 253 IR 166. His Honour acknowledged these authorities had involved the ultimate decision-maker relying on the advice of others on issues that were material to the appropriateness of taking the adverse action, and that this group could also be expanded to those who make tendentious statements of fact or engage in fact-finding which affects the decision in a substantial or operative way: at J[783]. Simple reliance on another's advice or statements as to matters of fact was not, his Honour concluded, sufficient to prove that the motivations of the other person "so affected" the ultimate decision-maker's reasoning that they should be characterised as a decision-maker. One needs to dig deeper and decipher the relative involvement of actors highlighting, by way of illustration, the significance of circumstance and degree when attending to this factual, forensic task.
36 His Honour then extracted the following portion of Gibbs (at 84-5):
Clearly, if the actual decision maker simply "rubber stamps" a decision in fact made by another, the purpose of that other will be a substantial operative factor. At the other extreme, if the actual decision maker truly believes the false and innocent reasons advised by the other person, the mind of the decision maker will not be tainted by the improper purpose of the other person. The problem assumes greater complexity when the decision is made by more than one person, as might be the case with the board of directors of a company, and as is often the case when the decision is made by a local government authority.
37 This extract continues on, by extension, with examples, on the spectrum where there is one decision-maker purportedly "affected" by others.
38 His Honour then considered, at J[784], whether Messrs Boxsell, Melzer and Cross, were, in effect, part of the decision-making process rather than simply part of the investigation process, citing his Honour's earlier consideration in another case of the seminal authorities on this issue: Ibarra Campoverde v Regional Health Care Group Pty Ltd [2017] FCCA 1502 at [71]-[76]. His reference to the analogous reasoning in Ibarra is unsurprising. In Ibarra, Mr Ibarra contended that employees who had sent emails and made comments (about the incident which had precipitated Mr Ibarra's dismissal) to the ultimate decision-maker, had made "material contributions to the ultimate decision" such that it could be characterised as a "collective undertaking": at [71]. The referenced portions of Ibarra espoused the following propositions: the mind of the respondent corporation may be located in more than one person exercising the executive power of the corporation (at [72], citing Wood at 19); where a person who contributed to the ultimate decision was influenced by a prohibited reason, the ultimate adoption of that affected or infected contribution by another person unaware of the infection may nonetheless mean that the impugned decision is found to be for the prohibited reason (at [74], citing Clermont Coal at [121]); and whether a person will be a decision-maker as distinct from being part of the investigative process depends on what in fact the individuals did with that information (at [75]). For example, did they assess the information and provide a recommendation to the ultimate decision-maker (at [75], citing Gibbs)?
39 His Honour then concluded that there was no persuasive evidence that Messrs Boxsell, Melzer and Cross were part of the decision-making process. It is noteworthy to recall that the primary judge had found that Mr Cross's report had not misrepresented the facts or expressed conclusions that lacked good faith because they were motivated by animus arising out of Ms Edgar's complaints, for the reasons referred to above. This is noteworthy context: Absent there being a prohibited reason, it is immaterial whether they were part of the decision-making process.
40 His Honour then postulated a number of hypotheticals in the alternative at J[784]:
Even if Mr Cross's report recounted evidence in a way that misrepresented the facts or expressed conclusions that lacked good faith because they were motivated by animus arising out of Ms Edgar's complaints, there was no evidence that Ms O'Rourke was aware that the report was affected by such shortcomings. Further, the evidence did not support a conclusion that Ms O'Rourke doubted the accuracy of the investigation report and so her decision-making would not have been tainted by what Ms Edgar alleges were the improper purposes of Messrs Boxsell, Melzer and Cross: Gibbs v Palmerston Town Council at [114].
41 There is a certain infelicity in this aspect of the reasoning. It may be accepted that the ultimate adoption of that affected or infected contribution by another person unaware of the infection may nonetheless mean that the impugned decision is found to be for the prohibited reason: Wong at [26]. However, the infelicity arises in the context of considering a hypothetical that did not arise in this case because (a) Mr Cross was not found to have the requisite prohibited animus; and (b) Ms O'Rourke did not merely adopt his report as the basis for the dismissal. Accordingly, whilst not correct, the proposition was not applied to the facts of this case because the circumstance did not arise.
42 Whilst his Honour refers to Gibbs at [114] (using the Austlii paragraph numbering), it is clear from this reasoning that his Honour, having dismissed the conclusion that Mr Cross was part of the decision-making process, turns his focus to Ms O'Rourke's motivations and whether they could have been tainted by what Ms Edgar alleges. His Honour noted at J[784]:
Moreover, as will be considered more fully shortly, it is apparent that Ms O'Rourke exercised independent judgment when deciding what was to be done in relation to Ms Edgar and based her decision and recommendation to Mr Spanner on objective evidence of Ms Edgar's attitude to her more senior colleagues in the Marketing department and of conduct engaged in by her distinct in character from the making of complaints.
43 His Honour thereafter, in an expansive way, makes good this conclusionary finding as to the independence of Ms O'Rourke's reasoning: Notation is made of the fact that Mr Cross's conclusions were relevant to Ms Edgar's dismissal "only to the extent that upon receipt of the investigation report" it was Ms O'Rourke who drew the rational conclusions regarding Ms Edgar not wanting to work with Mr Boxsell or Mr Melzer, highlighting this conclusion in her show cause letter to Ms Edgar and inviting Ms Edgar to show cause as to why her employment should not be brought to an end by reason of its untenability: at J[785]. There is express, repeated acceptance of Ms O'Rourke's evidence that it was Ms Edgar's failure to address satisfactorily the issues raised in the show-cause letter that led her to conclude that her employment had to be terminated (referring to Ms Edgar's response to the same effect). His Honour also expressly rejected that the conclusion was anything other than an independent one, finding that it was independent from any supposed tendentiousness in the findings expressed by Mr Cross in his investigation report: at J[787]. His Honour found that Ms O'Rourke's reasons were as she had deposed, including her express denial that they were based on Ms Edgar's complaints about the workplace and her claimed medical conditions: at J[787]. These findings were fortified by the fact that Ms Edgar had made clear, repeatedly, that she did not want to work with Mr Boxsell or Mr Melzer, to which the primary judge made multiple references: at J[786], [788].
