Adequacy of reasons
35 It is well-recognised that there is a judicial duty to provide reasons for most decisions, including for final decisions and "important interlocutory rulings": Wainohu v New South Wales (2011) 243 CLR 181; [2011] HCA 24 (French CJ and Kiefel J, as her Honour then was) at [54], see also [104]-[109] (Gummow, Hayne, Crennan and Bell JJ). It is also accepted that where reasons are provided, they must be adequate: DL v The Queen (2018) 266 CLR 1; [2018] HCA 26 (Kiefel CJ, Keane and Edelman JJ) at [32].
36 A failure to provide adequate reasons may amount to an error of law: see TechnologyOne Ltd v Roohizadegan (2021) 309 IR 202; [2021] FCAFC 137 (Rangiah, O'Callaghan and White JJ) at [108]; Carlisle Homes Pty Ltd v Barrett Property Group Pty Ltd [2009] FCAFC 31 (Tamberlin, Sundberg and Besanko JJ) at [45]-[46]; Police Federation of Australia v Nixon (2011) 198 FCR 267; [2011] FCAFC 161 (Lander, Gilmour and Gordon JJ) at [70]. However, the absence of reasons does not in itself indicate that a judge has erroneously exercised the discretion to award costs: Penfold v Penfold (1980) 144 CLR 311 (Stephen, Mason, Aickin and Wilson JJ) at 315-16. An appellate court will generally only intervene when "it is left with no choice" because the statement of reasons, looked at as a whole, betrays a miscarriage of justice: see Beale v Government Insurance Office (NSW) (1997) 48 NSWLR 430 (Meagher JA) at 444.
37 Further, adequacy is assessed in the context of the nature of the decision: see Wainohu at [56], cited with approval in DL v The Queen at [32]. Indeed, the extent to which a court must go in giving reasons is incapable of precise definition and is context specific: Housing Commission of New South Wales v Tatmar Pastoral Co Pty Ltd [1983] 3 NSWLR 378 (Hutley JA, with whom Samuels JA agreed) at 381; see also Mifsud v Campbell (1991) 21 NSWLR 725 (Samuels JA, with whom Clarke JA and Hope A-JA agreed) at 728. Whilst the basis of a decision should be apparent, this does not mean that the reasons given must be elaborate: IFTC Broking Services Limited v Commissioner of Taxation (2010) 268 ALR 1; [2010] FCAFC 22 (Stone, Edmonds and Jagot JJ) at [4]; Beale at 443. Reasons need only be given so far as is necessary to indicate to the parties why the decision was made and to allow them to exercise such rights as may be available to them in respect of it: Propell National Valuers (WA) Pty Ltd v Australian Executor Trustees Ltd (2012) 202 FCR 158; [2012] FCAFC 31 (Collier J, with whom Stone J agreed) at [146].
38 Dr Kitchen submits that where the dispute involves a form of "intellectual exchange, with reasons and analysis advanced on either side", the judge "must enter into the issues canvassed before him [or her] and explain why he [or she] prefers one case over the other". To the extent that this submission suggests that the primary judge was required to analyse each of the individual principal arguments put by Dr Kitchen, and to explain in her reasons why she did not accept each of them, this argument goes too far. A judge is permitted to decide the matter before them in a way which does not require the determination of each submission made by the parties: see Housing Commission of New South Wales (Mahoney JA) at 385. Indeed, the Full Court of this Court has accepted that an elaborate argument may not require elaborate reasons: IFTC at [4]. We consider that this is particularly the case in the context of a determination as to the appropriate costs order to be made.
39 Further, reasons can be adequate by a combination of what is expressly stated and the inferences that necessarily arise from what is expressly stated: ACN 005 565 926 Pty Ltd v Snibson [2012] VSCA 31 (Kyrou AJA, with whom Mandie and Hansen JJA agreed) at [81]. The reasons must, at the very least, "disclose the 'path' or 'route' by which the trial judge reached the ultimate conclusion in the judgment": Vicforests v Environment East Gippsland Inc [2023] VSCA 159 (Emerson P, Macaulay and Kaye JJA) at [277] citing Beale at 443-4.
40 We turn then to the issue of delay in the delivery of the judgment, which was more than 13 months after the date of final submissions. Dr Kitchen accepts that a delay in delivering judgment does not generally, of itself, give rise to appellable error, which is the correct approach: Sullivan v Trilogy Funds Management Ltd (2017) 255 FCR 503; [2017] FCAFC 153 (Allsop CJ, Farrell and Gleeson JJ) at [271]; NRM Corporation Pty Ltd v Australian Competition and Consumer Commission [2016] FCAFC 98 (Flick, Murphy and Griffiths JJ) at [132]-[134]. However, Dr Kitchen submits that the primary judge's delay in delivering judgment may explain the "deficiencies" in her Honour's reasons. He further submits that delay, at least where it is substantial, adds another dimension in considering the adequacy, or otherwise, of reasons. A judge's delay in giving judgment, it was said, could give rise to a reasonable apprehension by the losing party that the judge delayed giving judgment because he or she was unable to grapple adequately with the issues, and, in the end, had become attracted to the decision which was the easiest to make.
41 As to this submission, we accept that where there has been delay, the appellate court should take a more stringent approach in determining whether the primary judge's reasons are adequate: see Expectation Pty Ltd v PRD Realty Pty Ltd (2004) 140 FCR 17; [2004] FCAFC 189 (Carr, Emmett and Gyles JJ) at [68]-[73], cited with approval in Commonwealth of Australia v Sanofi (formerly Sanofi-Aventis) [2023] FCAFC 97 (Besanko, Perram and Yates JJ) at [377].
42 We turn then to consider the adequacy of the reasons of the primary judge.
43 At [9]-[15] J, the primary judge explained the principles applicable to an order for costs on an indemnity basis (about which no complaint is made). Her Honour then set out the submissions of Dr Kitchen and the Director at [20]-[21] J, before considering whether it was appropriate in the circumstances to make an order for indemnity costs at [22]-[29] J. These reasons included specific reasons for rejecting certain arguments advanced by Dr Kitchen, and they identified four reasons for her Honour's decision.
44 Read as a whole, the reasons contain the "path" or "route" by which the primary judge reached the ultimate conclusion in the judgment, being to decide to award costs on a party-party basis instead of on an indemnity basis as sought by Dr Kitchen. Further, they contained an express and implicit rejection of the arguments in Dr Kitchen's submissions as recited at [20] J, notwithstanding that the reasons did not analyse each submission expressly.
45 We can see no indication in the reasons that the primary judge became "attracted to the decision which was the easiest to make" or that her Honour was unable to grapple with the submissions made by Dr Kitchen (which were not in themselves especially complex). Further, the delay was not operative in the sense that there were no factual findings for her Honour to make, and no need to consider the demeanour or credibility of any witnesses (these being matters which are well-recognised as likely to be impacted by delay).
46 For these reasons, we consider that the primary judge's reasons are adequate, such that the decision below is not attended by sufficient doubt to warrant its reconsideration by an appellate court.
