Legal principles
22 In Wainohu v New South Wales (2011) 243 CLR 181 at [54]-[58], in considering whether the Crimes (Criminal Organisations Control) Act 2009 (NSW) was, or certain provisions of it were, invalid, French CJ and Kiefel J (as her Honour then was) said the following (at [54]-[58]) about the duty of judges to give reasons for decision:
54 The centrality, to the judicial function, of a public explanation of reasons for final decisions and important interlocutory rulings has long been recognised. In a passage from the first edition of Broom's Constitutional Law, published in 1866, the author said:
"A public statement of the reasons for a judgment is due to the suitors and to the community at large - is essential to the establishment of fixed intelligible rules and for the development of law as a science … A judgment once delivered becomes the property of the profession and of the public; it ought not, therefore, to be subsequently moulded in accordance with the vacillating opinions of the judge who first pronounced it."
That passage was said in the Supreme Court of Victoria to have "general application to all persons exercising judicial functions." Its universality was qualified in Public Service Board of New South Wales v Osmond by Gibbs CJ, who said that there was no "inflexible rule of universal application" that reasons be given for judicial decisions. His Honour, however, accepted that the requirement to give reasons is "an incident of the judicial process".
55 The duty upon judges to give reasons for their decisions has often been linked to the availability of rights of appeal against those decisions. A wider rationale, foreshadowed in the passage quoted from Broom, can be derived from the nature of the judicial function. In Housing Commission (NSW) v Tatmar Pastoral Co Pty Ltd, Mahoney JA, after referring to the importance of reasons for decision to the effective exercise of appeal rights, said:
"But, in my opinion, the requirement that reasons be given should not be limited to cases where there is an appeal. There is as yet no finally authoritative decision on this question. I think that the requirement should be seen as an incident of the judicial process."
The proposition that the provision of reasons for decision is an aspect of the judicial function has been supported by other decisions of the Supreme Courts of New South Wales, Victoria and Queensland.
56 Gummow J in Grollo described the essential attributes of the judicial power of the Commonwealth in familiar terms by reference to the resolution of justiciable controversies by ascertainment of the facts, application of the law and the exercise where appropriate of judicial discretion, adding "which are delivered in public after a public hearing, and, where a judge is the tribunal of fact as well as law, are preceded by grounds for decision which are animated by reasoning." Heydon J in AK v Western Australia described the duty of judges to give reasons for their decisions after trials and in important interlocutory proceedings as "well-established". His Honour adopted as a summary of the objectives underlying that duty an extra-curial statement by Gleeson CJ:
"First, the existence of an obligation to give reasons promotes good decision making. As a general rule, people who know that their decisions are open to scrutiny, and who are obliged to explain them, are more likely to make reasonable decisions. Secondly, the general acceptability of judicial decisions is promoted by the obligation to explain them. Thirdly, it is consistent with the idea of democratic institutional responsibility to the public that those who are entrusted with the power to make decisions, affecting the lives and property of their fellow citizens, should be required to give, in public, an account of the reasoning by which they came to those decisions."
The duty does not apply to every interlocutory decision, however minor. Its content - that is, the content and detail of the reasons to be provided - will vary according to the nature of the jurisdiction which the court is exercising and the particular matter the subject of the decision.
57 The connection between the duty to give reasons and the nature of the judicial power enunciated in Grollo, and the objectives which that duty serves, explained in AK, marks the duty as an incident of the judicial function whether or not the court making the relevant decision is subject to appeal. …
58 The provision of reasons for decision is also an expression of the open court principle, which is an essential incident of the judicial function. A court which does not give reasons for a final decision or for important interlocutory decisions withholds from public scrutiny that which is at the heart of the judicial function: the judicial ascertainment of facts, identification of the rules of law, the application of those rules to the facts and the exercise of any relevant judicial discretion.

23 The content of the duty to give adequate reasons depends upon the circumstances of the matter being considered. It is not necessary for reasons to be elaborate or lengthy for them to be adequate: Thorne v Kennedy (2017) 263 CLR 85 at [61].
24 The duty imposed on a judge of the Circuit Court on delivery of ex tempore reasons was considered in AAM17. In that case, the first respondent sought judicial review in the Circuit Court of a decision of the Administrative Appeals Tribunal affirming a decision of a delegate of the Minister refusing the grant of a protection visa. The first respondent was not legally represented before the Circuit Court and relied upon an interpreter. At the conclusion of the hearing the Circuit Court delivered ex tempore reasons for the orders it pronounced. At the time, the court's orders were interpreted for the first respondent but the oral reasons were not. The first respondent did not receive a transcript of the ex tempore reasons for judgment and had to prepare his notice of appeal to this Court without regard to any written reasons. The written reasons of the Circuit Court were published more than a month after the first respondent had filed his notice of appeal and outside the period in which a notice of appeal was required to be filed. Although this Court found that there was no error affecting the decision of the Tribunal, the appeal was allowed on the basis that the failure by the Circuit Court judge to have his reasons translated for the first respondent's benefit constituted a denial of procedural fairness.
25 The issue before the High Court in AAM17 was whether, as had been found to be the case on appeal, the failure to have ex tempore reasons translated at the time of their delivery coupled with the failure to produce written reasons in a timely fashion amounted to a denial of procedural fairness. At [22] Steward J (with whom Kiefel CJ, Keane, Gordon and Edelman JJ each agreed) held that the final instance of the right of either party arising from the Circuit Court judge's obligation to afford procedural fairness was at the time the parties made their closing submissions and thereafter procedural fairness had no role to play in respect of the matters the subject of the Circuit Court judge's decision. However, his Honour also observed that "[a]s a matter of general fairness, rather than independent legal duty, the first respondent ought to have had the benefit of translated ex tempore reasons or written reasons at an earlier time".
26 Commencing at [23] Steward J set out a number of propositions including the following concerning the position of the Circuit Court:
(1) the Circuit Court is an inferior court, has no inherent powers and, as a creation of Parliament, has no authority other than that conferred on it by legislation. In that regard neither the Federal Circuit Court of Australia Act 1999 (Cth) (FCCA Act) nor the Federal Circuit Court Rules 2001 (Cth) (FCCA Rules), being the legislation in force at the time, addressed the topic of whether the Circuit Court is required to give written reasons or, if ex tempore reasons were delivered, whether they were required to be translated: at [26];
(2) s 74(1) of the FCCA Act required an order of the Circuit Court to be in writing or reduced to writing as soon as practicable: at [27];
(3) s 75 of the FCCA Act concerned what is to happen if the Circuit Court reserves judgment and the judge who heard the proceeding "subsequently prepares orders and reasons" but is not available to publish them. His Honour held that the FCCA Act authorises a Circuit Court judge to give ex tempore reasons and final orders upon completion of a hearing and also to reserve judgment where it is not possible or desirable to deliver ex tempore reasons: at [28];
(4) the FCCA Rules did not resolve the issue that arose for determination and, while those rules made certain provision for the receipt of translated documents, no such provision was made in relation to giving judgment. His Honour said that "there was no reason to suppose that a 'judgment' or 'order' for the purposes of the FCCA Rules is subject to a requirement that it be translated to a non-English speaking litigant where no such obligation conditions the power to give judgment or make orders under the FCCA Act": at [29]; and
(5) the nature of the Circuit Court's jurisdiction also supports the giving of ex tempore reasons which are later published in written form with revisions: at [30].
27 At [32] Steward J said:
Sixthly, and contrary to the submission of the first respondent, where written reasons of a court are published following the giving of ex tempore reasons, those written reasons must be taken to be the authentic expression of the judgment of the court unless it is otherwise shown that those reasons had materially deviated from what had been announced in court. Such deviations might be demonstrated by calling for the transcript (or other recording) of the ex tempore judgment; by the production of notes taken by counsel or by an instructing solicitor of what was said; or even by evidence given by counsel or an instructing solicitor in lieu of such notes. In Bromley v Bromley, following the grant of a decree nisi of divorce, the wife sought the transcript of the judge's reasons for judgment. With two days left to appeal, a photograph of a revised transcript was produced by the shorthand writer to the wife, bearing the marked-up amendments and deletions made by the judge. The wife submitted that the changes that had been made were material in nature and urged the Court of Appeal to examine the original transcript. It was said that certain of the judge's findings of fact in the original transcript, or the way in which he expressed his findings of fact as recorded in that transcript, ill-accorded with the conclusion at which he ultimately arrived. The Court of Appeal refused to inspect the original transcript. Willmer LJ said that in the absence of evidence to show that the judge had "so altered his judgment as to change its whole character", it would be "improper" for an appellate court to look at the original transcript "merely because it is the original transcript". Importantly, his Lordship said:
"What we must look at is that which bears the stamp of the judge's approval, and on that must stand or fall the success of the appeal."

28 In CQX18 v Minister for Home Affairs [2019] FCA 386, in considering whether the primary judge's failure to produce a written version of his oral reasons before the time within which an appeal could be brought had expired, albeit in obiter, Perram J said at [15]-[18]:
[15] … I doubt that a failure to reduce an oral judgment to writing within the appeal period involves jurisdictional error. There are a number of reasons for this.
[16] First, it is not self-evident that there is any legal obligation on a Federal Circuit Court Judge to produce a written version of oral reasons at all. No such requirement appears in the Federal Circuit Court Act or the FCR. The Federal Circuit Court is an inferior court and its procedures are to be found in its constitutive legislation and in what may legitimately be inferred from that legislation: Palmer v Clarke (1989) 19 NSWLR 158 ('Palmer v Clarke') at 166-167 per Kirby P (citing Ex parte Currie; Re Dempsey (1969) 70 SR (NSW) 443 at 447 per Herron CJ, Wallace P and Manning JA). It may in light of that be doubted, I think, that the Federal Circuit Court even has a power to revise its oral judgments (although there is no occasion presently to express a concluded view on that matter). If there is no obligation to produce a written version of oral reasons then a fortiori there can be no such obligation to produce the written version at any particular time.
[17] Secondly, whilst one may accept that the Court could produce a written version of its reasons if it chose, there is much to be said for the view that once it has pronounced its orders and given orders it is functus officio and has no further legal function: Palmer v Clarke at 172 per Kirby P, and 174 per Priestley JA; cf CLU16 v Minister for Home Affairs [2019] FCA 147 at [18] per Rares J. As such, it is conceptually difficult to see how the subsequent production of a written set of reasons can have any impact on the earlier exercise of jurisdiction.
[18] Thirdly, if a failure to produce a written set of the oral reasons within the appeal period were a jurisdictional error, it would be difficult to ascertain when the error was made. One could not know until the expiry of the appeal time (or until the earlier delivery of the written reasons) whether the error had been made. Until either of those events, the status of the Court's orders would be essentially unknowable. This matters because an order made by an inferior court in excess of its jurisdiction is invalid. Particularly where questions of contempt of court may intrude, it is unsatisfactory to have the orders of the court in an unknown state of validity pending ascertainment of whether the written reasons are delivered within the appeal period.
