Issue 1: The finding that Mr Lowbeer was not liable for Mr Austin's costs
59 The first issue concerns a challenge to the factual finding by the primary judge that Mr Austin was engaged by the Congregation and Mr Lowbeer had no liability, however remote or contingent, to pay Mr Austin's legal costs.
60 An appeal to this Court is by way of rehearing. Within the constraints marked out by the nature of the appellate process, there must be real review: Fox v Percy [2003] HCA 22; (2003) 214 CLR 118 at [25]. The task of this Court is to correct error. Where factual findings are challenged, they must be demonstrated to be wrong: Branir Pty Ltd v Owston Nominees (No 2) Pty Ltd (2001) 117 FCR 424; [2001] FCA 1833 at [22]-[30].
61 Where the relevant facts are incontrovertible facts or are the subject of uncontested testimony then an appeal court may interfere with findings that have been shown to be contrary to those facts. The court may also intervene if the factual findings at first instance were "glaringly improbable" or "contrary to compelling inferences": Robinson Helicopter Company Inc v McDermott [2016] HCA 22 at [43]. The quoted phrases are from the reasons of Gleeson CJ, Gummow and Kirby JJ in Fox v Percy at [28]-[29] where their Honours were dealing with those instances where there was a contest between performing the function of undertaking a real review, on the one hand, and recognising the limits of the appellate process, on the other. In such instances, the court in dealing with challenges to factual findings below will need to evaluate the extent to which the finding depends upon an advantage enjoyed by the trial judge: Aldi Foods Pty Ltd v Moroccanoil Israel Ltd [2018] FCAFC 93 at [2]-[10] (Allsop CJ) and [45]-[54] (Perram J), both of with whom Markovic J agreed. Where the advantage is considerable, the court will generally confine any interference with those findings to cases where the findings are glaringly improbable or contrary to compelling inferences.
62 As we have noted, the factual finding as to the terms of the engagement of Mr Austin was made by inference. The inference was drawn from facts that were not really in contest. The relevant facts were of narrow compass. Therefore, it may be accepted that this is a case where the primary judge had no special advantage over this appeal court in drawing inferences from those facts. In the language used by Gleeson CJ, Gummow and Kirby JJ in Fox v Percy, in this case there are no "constraints" as to the review of the factual findings that arise from the nature of the appellate process. So, issues of the kind considered in Starkey on behalf of the Kokatha People v State of South Australia [2018] FCAFC 36 at [13]-[31], [355], [402] do not arise here.
63 For the following reasons, it has not been demonstrated that there was error in the factual finding by the primary judge as to what was agreed concerning the engagement of Mr Austin.
64 Much of the argument advanced in support of the appeal on issue 1 was to the effect that there was no issue before the primary judge as to whether there was a valid costs agreement between Mr Lowbeer and Mr Austin. For reasons already given, we do not accept that was the case.
65 Otherwise, the submissions for Mr Lowbeer relied upon the fact that Mr Austin was on the record for Mr Lowbeer in the proceedings determined by Rares J and the costs order was made in favour of Mr Lowbeer.
66 However, the arrangements that had been made concerning the legal costs of those proceedings were not scrutinised by Rares J. As we have explained, Rares J proceeded on the usual basis in making such costs orders, which is to assume the existence of a retainer unless an issue is raised. Therefore, there was no forensic inquiry or determination of the issue as to who was liable for those costs. In those circumstances, the 2014 costs orders did not reflect a determination after a considered hearing of a kind that provides a practical guarantee of reliability.
67 Then it was submitted in support of Mr Lowbeer's appeal that the content of the email communications was explained by the Congregation's obligation to indemnify. However, there are a number of difficulties with that submission given the terms of the emails and the state of the other evidence.
68 First, the Congregation was not acting as an indemnifying party because it was not agreeing to pay all the costs that had been incurred in the Supreme Court proceedings. Rather, it was seeking to make a different arrangement whereby action would be taken against Rabbi Tov-Lev, Mr De Varda and others at the Congregation's cost to enforce the Supreme Court costs order and Mr Lowbeer would be paid out of the monies recovered from that action.
69 This was not the exercise of a right of subrogation. Further, as already noted, a party who has not paid the amount required by the indemnity is not subrogated.
70 Second, Mr Austin had acted for the Congregation in the Supreme Court proceedings and Mr Lowbeer had been represented by other lawyers. This historical context supported an inference that Mr Austin was engaged by the Congregation.
71 Third, it was a simple matter for Mr Austin to give evidence as to the actual arrangements made concerning his engagement and to produce any agreement and any invoices, but he did not do so.
72 Fourth, when questioned by Mr De Varda, Mr Austin did not say that he had been engaged by Mr Lowbeer. Rather, he said that he was acting for Mr Lowbeer "as trustee for" the Congregation and there had been an equitable assignment of the debt. Of course, an equitable assignment of the right to recover the costs would mean that it was the Congregation that was ultimately entitled to the monies paid under those orders and that the liability, at least in equity, was to the Congregation, not Mr Lowbeer.
73 Fifth, in the email exchange set out at [46] above there was first an inquiry as to whether the Congregation had given instructions to Mr Austin to commence bankruptcy proceedings (2 May 2013). Then there was a response from the Congregation saying that as Mr Austin was acting for Mr Lowbeer in the enforcement of the order, then Mr Lowbeer may instruct him and then look to the Congregation for the amount not recovered (3 May 2013). Mr Lowbeer then sought confirmation that as neither he nor Caunt and Lowbeer had any costs agreement with Mr Austin, the Congregation would cover all costs of recovery (6 May 2013). There was a response that the Congregation "will meet" (emphasis added) the costs of the recovery action (10 May 2013). In those circumstances, taking account of the other evidence, it was open to infer that the result was that the Congregation agreed that it would engage Mr Austin and that is what happened.
74 Sixth, to the extent that submissions were advanced to the primary judge that the payment by the Congregation of the 2014 costs order made by Rares J in favour of Mr Lowbeer gave rise to a "right of recoupment", an indemnifying party has a right to reimbursement: Stewart v Atco Controls Pty Ltd (in liq) at [50]. Though not amplified in any real way before the primary judge, the claim to recoupment would appear to be of that character. However, a claim of that kind would have to be brought by the Congregation against Rabbi Tov-Lev and Mr De Varda.
75 If the claim to recoupment be a separate expression of the basis for subrogation, the concept of unjust enrichment is not to be seen as supplying a sufficient application of the doctrine of subrogation in any particular case: Bofinger at [85]. Views to the contrary in Banque Financiere de la Cite v Parc (Battersea) Ltd [1999] 1 AC 221 should not be applied: Bofinger at [96]-[98].
76 Outside the emails, it was separately submitted that it should be inferred from the existence of cl 116 of the articles of association of the Congregation that the proceedings before Rares J had been pursued by the Congregation as a subrogated party. If that was the case then there would be a liability on the part of Mr Lowbeer for the costs, but they had been paid by the Congregation as an indemnifying party. In those circumstances, the payment under the indemnity would not mean that there was no liability on the part of the indemnified party to meet the costs. Rather, the situation would be of the kind explained in Coshott v Woollahra Municipal Council [2008] NSWCA 176 at [11].
77 However, there are a number of difficulties with this submission.
78 First, it disregards the other evidence, particularly, the email exchange and the oral evidence of Mr Austin.
79 Second, it disregards the significance of the failure to lead evidence about what was actually agreed as to the engagement of Mr Austin, the terms of engagement and the accounts rendered in respect of the legal work relating to the proceedings heard by Rares J. Where material is peculiarly within the knowledge of a party then it may be sufficient for the opposing party to adduce slight evidence of a matter in issue. If a decision not to call the evidence is then made by the party with the knowledge then that party bears the risk that the court may draw inferences contrary to its interests: Gerrard Cassegrain & Co Pty Ltd v Cassegrain (2013) 87 NSWLR 284; [2013] NSWCA 453 at [26].
80 Third, when the proceedings were heard by Rares J, the Congregation had not indemnified Mr Lowbeer in respect of his defence costs of the Supreme Court proceedings. Instead of the Congregation acknowledging that obligation and paying all the costs incurred by Mr Lowbeer (or Caunt and Lowbeer) in the Supreme Court proceedings, it proposed an arrangement whereby it would not pay the assessed amount of the Supreme Court costs order. Rather, it would pay immediately $13,635.12 (being the costs actually incurred by Mr Lowbeer over and above that assessed amount), and the Congregation's lawyer in the Supreme Court proceedings would be engaged to pursue bankruptcy proceedings for the assessed amount. The costs of those enforcement proceedings would be paid by the Congregation. Payment to Mr Lowbeer of any unrecovered amounts would only occur after those steps had been taken. These are not the actions of a party accepting an obligation to indemnify.
81 Fourth, the terms of cl 116 of the articles of association provide for an auditor (amongst other persons) of the Congregation to be indemnified out of the funds of the Congregation against all liability incurred as auditor (amongst other roles) "in defending proceedings". The bankruptcy proceedings were proceedings commenced by Mr Lowbeer, not proceedings defended by him. Confronted with that aspect, counsel appearing for Mr Lowbeer submitted that cl 116 "was the source of the obligation which then became a positive obligation through arrangements between the Congregation and Mr Lowbeer". These arrangements were then described as contractual and, by implication, were covered by the indemnity rights originally established as relating to the Supreme Court proceedings. These submissions expose the difficulties in reaching any conclusions from the terms of cl 116 as to what the arrangements may have been between Mr Austin and the Congregation concerning the costs of the proceedings before Rares J.
82 For these reasons, issue 1 should be determined adversely to Mr Lowbeer and ground 1 should not be upheld.
