LOGAN J:
1 I have had the privilege of reading in draft the reasons for judgement of Charlesworth J.
2 I have the misfortune of finding myself in respectful disagreement with her Honour as to the disposition of this appeal. I use the word, "misfortune" advisedly. That is because, in modern times, there is an unfortunate tendency abroad in some quarters of the Executive and in some of the popular press to pillory those in the judiciary and, for that matter, those in the Executive whose function it is to conduct independent merits review, who discern some injustice in law or fact in the way in which a Minister of State has dealt with a question concerning the visa of a person convicted of sexual offences relating to children. So the misfortune lies in the prospect of recent history repeating itself, given this dissent. Yet the judicial obligation is to do right, as one understands the law, without fear, favour, affection or ill-will (and a like point may be made by analogy in relation to merits review). It would be antithetical to that obligation to do otherwise because of some apprehended, personal misfortune.
3 The three offences in respect of which the appellant, Clive Ronald Dunn, was convicted and sentenced - two involving offences against Commonwealth law (accessing and making available child pornography using a carriage service), and one against Victorian law (possessing child pornography) - were, to any right-thinking person, vile and sinister. That is so even though the overall period of imprisonment imposed is, necessarily, indicative of lower order criminality. The sinister quality in such offences is that the prurient interest which drives their commission creates, as the learned sentencing judge noted, a market for the base exploitation of the most vulnerable and innocent in order to satisfy it. In this sense, they are not victimless crimes.
4 The very nature of the offences committed by Mr Dunn was such that, inevitably, there was a sure foundation for Ministerial satisfaction that he did not pass the "character test" for which the Migration Act 1958 (Cth) (the Act) (s 501(6)(e)) provides. In turn, this satisfaction yielded a mandatory obligation to cancel his visa (s 501(3A)).
5 Mr Dunn took up the opportunity, necessarily extended to him by the Minister so as to comply with s 501CA of the Act, to make representations as to why the Minister should exercise his discretion under s 501CA(4) to revoke the cancellation of his visa.
6 In the absence of provision to the contrary, the exercise of the Minister's power to decide whether or not to revoke the cancellation was regulated by the principles of natural justice (sometimes termed procedural fairness): Annetts v McCann (1990) 170 CLR 596, at 598; Jarratt v Commissioner of Police for New South Wales (2005) 224 CLR 44, at 61 [51] and Saeed v Minister for Immigration and Citizenship (2010) 241 CLR 252 at 258 [11]. Materially, that meant that Mr Dunn was "entitled to know the case sought to be made against him and to be given an opportunity of replying to it": Kioa v West (1985) 159 CLR 550 at 582.
7 That this principle of natural justice regulated the exercise of the Minister's power was common ground between the parties. The controversy between them was whether, in the events which transpired, the Minister violated this principle.
8 Materially, the Minister's findings, at para 69 of his reasons, were that:
(a) if Mr Dunn reoffended in a similar manner, there is a cost to the community in policing and administering the criminal justice system; and
(b) in relation to policing sexual child exploitation material, those exposed to the material when policing and administering the criminal justice system may suffer psychological harm.
These were hardly gratuitous findings. They were each findings which were adverse to Mr Dunn. They were findings which, with others, informed the Minister's decision not to revoke the cancellation of Mr Dunn's visa.
9 The Minister signified to Mr Dunn, prior to the making of his decision, that a factor to which he would advert was the risk to the community presented by any reoffending by him. Because the Minister chose to advert to such a risk, it is unnecessary to decide whether the Act obliged him to do that. Accordingly, I refrain from expressing any view on that subject.
10 That there would be a cost to the community in policing and administering the criminal justice system was a logical and inevitable corollary of any reoffending conduct. It does not, in my view, with all due respect to those who have a different view, including the learned primary judge, follow that it was "blindingly obvious" (cf Applicants M1015/2003 v Minister for Immigration and Multicultural & Indigenous Affairs [2004] FCA 1309 at [54] per Weinberg J) that this would be taken into account in an adverse way or at all in the making of the Minister's decision. Of course if the risk of reoffending came to fruition, the impact would not be limited to children exploited in Australia or abroad for pornographic image making but would necessarily include policing and criminal justice system administration costs. But there is a very real difference between informing a person that one is going to take into account potential risk to the community and informing that person that one is also going to take into account potential financial cost to the community.
11 Once again with all due respect to those who hold a different view, including the learned primary judge, I am also unable to accept that the prospect that those policing and administering the criminal justice system may suffer psychological harm was either "blindingly obvious" or, for that matter, obvious at all, at least at present.
12 One way of demonstrating this is by analogy.
13 These days, there is a general understanding, not just in the military but also in the wider community, that members of the Defence Force in contact with an enemy force or who perform duty in an environment where the risk of such contact or of other causes of death or wounds is pervasively and persistently present are prone to suffer combat stress reaction or, to use a more frequently encountered term, post-traumatic stress disorder (PTSD). One indication of that contemporary, general understanding is to be found in the existence of a specific statement of principles concerning PTSD in the form of a statutory instrument made under the Veterans' Entitlements Act 1986 (Cth). Exactly when that condition will manifest itself and its severity is individually specific, but that there is a risk of the condition for those on active service is generally understood in modern times.
14 That contemporary, general understanding may be contrasted with the position, now over a century ago, during the First World War. Then, that risk was not generally understood even within the military, let alone by the wider community. In the militaries of both the Allied and the Central Powers in that conflict, soldiers were court martialled, sentenced to death and (save for Australian troops, because of our reservation to our government of a need to consent) executed for behaviours some of which we would now ascribe to symptoms of PTSD. A century later, with greater, general understanding of the risk, some countries have even pardoned those executed in that war: see, for example, s 359, Armed Forces Act 2006 (UK). Over the course, and in the aftermath of that war, there was a developing understanding amongst medical officers and some general service officers that there may be a genuine, underlying medical condition, termed by some at the time, "shell shock": see A G Butler, Official History of the Australian Army Medical Services, 1914-1918, Volume III - Special Problems and Services (1st edition, 1943), Chapter II - Moral and Mental Disorders. The risk of its contraction was not then generally understood in the wider community. The behaviours of all too many veterans after that war, along with advances in the disciplines of psychology and psychiatry prompted by the experience of that war may, in hindsight, have been a precipitator of later, wider community understanding.
15 The point of this excursion into history is that, as once with what we now term PTSD, so perhaps in the future it will prove in relation to particular psychological risks presented by the undertaking of particular policing and criminal justice administration duties. What is or has become trite to some may presently come as a revelation to many. In time, an understanding once confined to particular occupational groups may become pervasive to the point where, truly, the subject is "blindingly obvious". That there may be a particular risk of the type of psychological harm to which the Minister referred may be known to some within the police or medical profession. It may also be known to some in the legal profession or the judiciary, especially including those of us who, for example, have appeared or presided in cases arising under, for example, the Dangerous Prisoners (Sexual Offenders) Act 2003 (Qld), to say nothing of encounters in criminal, workers' compensation or civil jurisdictions. But it is presently a large step to extrapolate from such encounters any general "obviousness".
16 This aside, it does not follow that alerting a person in advance that one is proposing to take into account as an adverse consideration risk to the community also alerts that person to the fact that one is proposing to take into account a risk of psychological harm to those undertaking of particular policing and criminal justice administration duties.
17 The Minister did not in his reasons categorise the existence of a risk of psychological harm as a notorious fact. In any event, the existence of such a risk was not a notorious fact. Such facts are those which are common knowledge or part of ordinary experience. They would include, but not be limited to, those of which a court might take judicial notice. In my view, this particular risk was one of those which "while not so indisputable as to be considered within every ordinary person's common sense, are nonetheless susceptible to resolution by an expert adjudicator": D B. Rodriguez, "Official Notice and the Administrative Process", (1990) 10 Journal of the National Association of Administrative Law Judiciary, Issue 1, article 3, p 51.
18 The Minister had no material in the form of expert evidence from a third party before him as to a risk of suffering psychological harm by those exposed to child pornographic material when policing and administering the criminal justice system. Such third party material could but need not have been in the form of a proof of evidence or report by a person with relevant expertise. It might, for example, have alternatively been found in a statement in a learned article in a journal by an author apparently possessing relevant qualifications and experience which was placed before the Minister.
19 That the Minister had no such material did not mean that, in public administration, he was unable, for example, to draw on personal knowledge and understanding of the existence of such a risk. The Minister's obligation was to make findings based on logically probative material. On the one hand, he could not act on rumour or speculation; on the other, he was not in any way bound by the rules of evidence. Material which would be admissible in a judicial proceeding is of course permissibly considered in public administrative decision-making and may, because of its having the quality of conformity with the rules of evidence carry singular weight: R v War Pensions Entitlement Appeal Tribunal; Ex parte Bott (1933) 50 CLR 228, at 256 per Evatt J. Nonetheless, to conceive of "evidence" in the sense of only that which is admissible in the exercise of judicial power by a court would be to borrow "from the universe of discourse which has civil litigation as its subject": Minister for Immigration and Ethnic Affairs v Wu Shan Liang (1996) 185 CLR 259 (Wu Shan Liang), at 282. This is but one example of the very different nature of administrative decision-making by comparison with judicial decision-making: Wu Shan Liang (ibid); Mahon v Air New Zealand [1984] AC 808, at 814. A judge must decide a case by reference to the evidence presented by the parties at a trial, including facts of which judicial notice may be taken (as to the latter, in this Court, s 144 of the Evidence Act 1995 (Cth) is applicable). A judge is not permitted to find facts based on personal knowledge of their existence: Hurpurshad v Sheo Dyal (1876) LR 3 Ind App 286; Palmer v Crone [1927] 1 KB 804; Thomas v Thomas [1961] 1 WLR 1. If, by virtue of pre-parliamentary occupational experience or by knowledge gained through the exercise of Ministerial office, the Minister had gained specialist knowledge about a risk of psychological harm, that knowledge would be capable of supplying a logical foundation for a finding as to the existence of that risk: J A Smillie, The Problem of "Official Notice": Reliance by Administrative Tribunals on the Personal Knowledge of Their Members [1975] Public Law 64, at 66.
20 Whether he had specific material before him or proposed to draw on relevant personal knowledge and experience, the exercise of the Minister's power was, as I have indicated already, regulated by the principles of natural justice. One such principle, is the avoidance of bias, be it actual or in appearance. Thus, if the Minister were relying upon personal knowledge and experience as the basis for a conclusion as to the existence of such a risk, that, in itself would require singular disclosure of such intended reliance and overt receptiveness to being challenged in that knowledge and experience by any material which called into question the existence, nature and extent of any such risk.
21 In this case, it is not possible to determine whether the Minister's finding as to the existence of such a risk was based on his personal knowledge and experience, because his statement of reasons does not disclose this. But the jurisdictional error allegedly made by the Minister and not upheld by the primary judge was not put either on the basis of an absence of material to support a finding as to the existence of the risk or on the basis of some actual or apprehended bias on the part of the Minister. Rather, the jurisdictional error was said to be found in a denial of procedural fairness grounded in a failure to be afforded an opportunity to be heard in relation, to this risk and the subject of potential financial cost to the community.
22 Prior to making his decision, the Minister made no disclosure to Mr Dunn that he intended to take into account as a consideration a risk of the suffering of psychological harm by those policing and administering the criminal justice system to the end of detecting, investigating and prosecuting any reoffending by him. Nor, given that absence of disclosure of the consideration itself, did he disclose any material, be that his own opinion based on personal knowledge and experience or anything else upon which he proposed to rely, even that it was in his view a notorious fact, for a finding that such a correlative risk existed. Nor, necessarily, did the Minister afford Mr Dunn an opportunity to be heard in respect of that consideration.
23 It follows, in my view, that, in making his decision, the Minister did not comply with the principles of natural justice, in that he did not offer Mr Dunn an opportunity to be heard in relation to the two adverse considerations mentioned.
24 As it happens, it was also concluded in Durani v Minister for Immigration and Border Protection (2014) 314 ALR 130 and in Jione v Minister for Immigration and Border Protection (2015) 232 FCR 120 that the Minister had failed to afford the person affected by his decision an opportunity to be heard. Like the present case, these were but examples on particular facts of how an obligation to extend such an opportunity arises. It is always necessary to advert to the nature and extent of the particular prior notice (if any) given to the person affected and the particular adverse consideration ultimately taken into account in deciding whether an administrative decision-maker who is obliged to comply with the principles of natural justice has failed to comply with those principles by not affording that person an opportunity to be heard. These cases offered illustrations by analogy that supported Mr Dunn's contention as to how the principles applied in the circumstances of his case but neither bound the learned primary judge to find in his favour.
25 Even though he concluded that there had been no denial of an opportunity to be heard in the manner alleged by Mr Dunn, the learned primary judge considered that, even if there had been, no practical injustice had resulted. With respect, I am unable to accept this.
26 As with the grant of constitutional writs by the High Court under s 75(v) of the Constitution or of relief by this Court under s 39B of the Judiciary Act 1903 (Cth), the grant of relief by this Court in the exercise of the original jurisdiction conferred by s 476A of the Act is a matter of discretion. As to the principles attending the exercise of such a discretion, the following passage from the judgment of Latham CJ, Rich, Dixon, McTiernan and Webb JJ in R v Commonwealth Court of Conciliation and Arbitration; Ex parte Ozone Theatres (Aust) Ltd (1949) 78 CLR 389 at 400 was expressly approved by Gleeson CJ, Gummow, Callinan, Heydon and Crennan JJ in SZBYR v Minister for Immigration and Citizenship (2007) 81 ALJR 1190 at [28] as offering relevant albeit not exhaustive guidance:
For example the writ may not be granted if a more convenient and satisfactory remedy exists, if no useful result could ensue, if the party has been guilty of unwarrantable delay or if there has been bad faith on the part of the applicant, either in the transaction out of which the duty to be enforced arises or towards the court to which the application is made. The court's discretion is judicial and if the refusal of a definite public duty is established, the writ issues unless circumstances appear making it just that the remedy should be withheld.
[Emphasis added]
27 The sentiments entailed in the consideration emphasised, "if no practical injustice could ensue" were taken up in the following observation made by Gleeson CJ in Re Minister for Immigration and Multicultural and Indigenous Affairs; Ex parte Lam (2003) 214 CLR 1 at 14 [37]:
Whether one talks in terms of procedural fairness or natural justice, the concern of the law is to avoid practical injustice
28 If there are present other considerations that, inevitably, would support the making of the decision challenged on judicial review that procedural fairness was denied in respect of another consideration taken into account it might nonetheless aptly be concluded that no "practical injustice" resulted from that denial.
29 Here the considerations were not all one way. The Minister eloquently, with respect, acknowledged this in his reasons. In these circumstances, a judicial conclusion that no practical injustice has resulted from a denial of procedural fairness in respect of particular adverse considerations taken into account is fraught with the risk of the Court substituting its own evaluative judgement on the merits for a decision that Parliament has consigned to the Minister to make. To do that is to step outside the legitimate role of a court conducting judicial review: Attorney-General (NSW) v Quin (1990) 170 CLR 1 at 35-37 per Brennan J. This, with respect, is what the learned primary judge has done, in my view.
30 It is by no means impossible to conceive of submissions which might have been made on behalf of Mr Dunn had he been alerted in advance to the prospect that the Minister proposed to consider adversely to the revocation of the cancellation of his visa both the cost of and a risk of the suffering of psychological harm to those policing and administering the criminal justice system to the end of detecting, investigating and prosecuting any future reoffending by him. He might, for example, have put that the risk of reoffending was so low and the prospect that such a cost and psychological harm risk (if he acknowledged the existence of that particular risk) would be present in any event such that these were considerations of no adverse weight in his individual case at all. It is enough to grant relief that compliance with the relevant natural justice obligation might have made a difference, not that it must: Stead v State Government Insurance Commission (1986) 161 CLR 141 at 145.
31 For these reasons, I would allow the appeal, quash the decision of the Minister and remit the matter to him for deciding according to law the question of whether to revoke the cancellation of Mr Dunn's visa.
I certify that the preceding thirty-one (31) numbered paragraphs are a true copy of the Reasons for Judgment herein of the Honourable Justice Logan.
