Ground 1 - Vitiation of a state of satisfaction by a misunderstanding of evidence
33 It may be accepted, as the applicant contends, that the requirement under s 501CA(4)(b)(ii) of the Act that the Minister (or the Tribunal in the Minister's stead) be satisfied that there is another reason to revoke the cancellation decision is a precondition to the valid exercise of the power to so revoke contained in the chapeau of s 501CA(4). Similarly, that power is also conditioned upon the existence of the matters prescribed by s 501CA(4)(a), that the applicant make representations in accordance with the invitation that the Minister is required to give under s 501CA(3). It is not controversial that this requirement was satisfied.
34 Both the requirements of s 501CA(4)(a) and s 501CA(4)(b)(ii) are jurisdictional facts, the existence of which, are necessary preconditions to the valid exercise of the power to revoke a cancellation decision. As the Full Court (Collier, Reeves and Derrington JJ) in Ali explained (at [40]-[42]):
40 The jurisdictional fact in subs (4)(a) is something which might be objectively ascertained (an objective jurisdictional fact). In this case the Minister made the observation that the appellant had made representations about the revocation of the original decision. That was not something of which he was required to be satisfied. It was merely an event which needed to occur and its existence or otherwise would always be open to full merits review.
41 The matters in subs (4)(b)(i) and (ii) are subjective jurisdictional facts. The question for a court on review is not whether they existed, but whether the Minister was satisfied that either existed. By his reasons the Assistant Minister recorded that he was not satisfied that the appellant passed the character test and, nor was he satisfied that there was "another reason why the original decision should be revoked". The consequence was that the power in the chapeau, which was conditioned on the satisfaction of the jurisdictional facts in subs (a) and (b), was not enlivened.
42 The shielding of jurisdictional facts from curial review by interposing a subjective deliberation on a matter is a long established legislative drafting technique: Bankstown Municipal Council v Fripp (1919) 26 CLR 385 at 403, acknowledged by Gummow J in Minister for Immigration and Multicultural Affairs v Eshetu (1999) 197 CLR 611 (Eshetu) at [130], and repeated by his Honour with McHugh J in Re Minister for Immigration and Multicultural Affairs; Ex parte Applicant S20/2002 (2003) 77 ALJR 1165 (S20/2002) at [54]. Although the existence of a subjective state of mind is not beyond review by the Court, the grounds upon which it may be "reviewed" are limited. An early identification of those grounds was undertaken by Dixon J in Avon Downs Pty Ltd v Federal Commissioner of Taxation (1949) 78 CLR 353 (Avon Downs) at 360. Those grounds have been added to and refined over the years: MacCormick v Federal Commissioner of Taxation (1945) 71 CLR 283; Buck v Bavone (1976) 135 CLR 110 at 118-119 per Gibbs J; Minister for Immigration and Multicultural and Indigenous Affairs v SGLB (2004) 78 ALJR 992 at [38] per Gummow and Hayne JJ; Minister for Immigration and Citizenship v SZMDS (2010) 240 CLR 611 (SZMDS); EHF17 v Minister for Immigration and Border Protection (2019) 272 FCR 409. Despite that elaboration in the later cases, the principles on which subjective jurisdictional facts may be reviewed are nevertheless generally referred to as "Avon Downs principles". That being said, where the state of mind on which the operation or exercise of a provision or power is conditioned is vitiated by an Avon Downs error, any subsequent purported exercise of power will necessarily be affected by jurisdictional error: S20/2002 at [59].
(Emphasis added.)
35 The applicant also relied on Guclukol, where the Full Court (Katzmann, O'Callaghan and Derrington JJ) said (at [16]):
Before considering that submission, it is convenient to briefly consider the functional operation of s 501CA(4), despite the absence of any substantive submissions being provided to the Court on this issue. In Ali v Minister for Home Affairs [2020] FCAFC 109 (Ali), the Full Court assayed at [39] - [44] the recent authorities and concluded that the discretionary power in the chapeau to s 501CA(4) was conditioned upon the existence of two subjective jurisdictional facts, the second being the Minister's satisfaction "that there is another reason why the original decision should be revoked". It follows that, where the Court is called upon to ascertain whether a vitiating error has occurred in the course of reaching the required state of mind, the principles relating to subjective jurisdictional fact review, sometimes referred to as "Avon Downs principles", are initially applicable. It may be that, once a vitiating error in the formation of the state of mind is identified, the subsequent purported exercise of power will involve a jurisdictional error due to the non-existence of the circumstance on which the power was conditioned. See generally, Derrington R, "Migrating Towards a Principled Approach to Reviewing Jurisdictional Facts" (2020) 27 AJ Admin L 70.
(Emphasis added.)
36 It may be accepted from these two passages that the Court's task on review of the decision-maker's satisfaction under s 501CA(4)(b)(ii) of the Act is to consider whether the existence or not of that subjective jurisdictional fact has been vitiated by an error of the kind described by Dixon J in Avon Downs (at 360) and in line with the principles enunciated in the subsequent decisions identified in Ali (at [42]).
37 It must also be observed that the above quoted passage from Guclukol, and an earlier paragraph from Ali (at [39]) suggest that the existence of the jurisdictional facts prescribed by s 501CA(4)(a) and s 501CA(4)(b)(ii) (or (i)) enliven the discretionary power of the Minister to revoke a cancellation decision contained in the chapeau of s 501CA(4). To the extent that these decisions appear to suggest that the Minister retains some residual discretion to exercise or not exercise the power to revoke the cancellation decision, after satisfaction of the preconditions contained in s 501CA(4)(a) and s 501CA(4)(b), there is also substantial authority for the contrary view: see for instance Katzmann J's reasons (at [2]-[7] and the authorities cited therein) in Tohi v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2021] FCAFC 125; cf Derrington J's reasons in Tohi (at [35]-[38]) and [50]-[51]). It is unnecessary to decide this point in the present case and neither party advanced submissions as to the proper construction of s 501CA(4) as a whole. It suffices for present purposes to accept simply that the existence or not of a jurisdictional fact rendered subjective by the requirement that a decision-maker reach a state of satisfaction will be vitiated by error if the decision-maker commits an Avon Downs error.
38 The applicant's contention is that the Tribunal's misunderstanding of the underlying statistical basis of the screening tool, and its apparent view that the attribution of a 'low risk' of reoffending to the applicant was the subjective view of prison assessors, vitiated its satisfaction that there was not another reason to revoke the cancellation decision. The Minister's submissions in response to this ground were directed primarily to demonstrating that the Tribunal had clearly given active intellectual consideration to the representations as to reoffending generally and indeed specifically in relation to the screening tool. It is not disputed that it is generally unnecessary for the Tribunal to refer to every piece of evidence or contention advanced by an applicant but must consider significant and clearly articulated representations as a whole: Minister for Home Affairs v Buadromo [2018] FCAFC 151; (2018) 267 FCR 320 per Besanko, Barker and Bromwich JJ (at [48]-[49]); Navoto v Minister for Home Affairs [2019] FCAFC 135 per Middleton, Moshinsky and Anderson JJ (at [88]) and Matthews v Minister for Home Affairs [2020] FCAFC 146 per Middleton, Perry and O'Bryan JJ (at [29]). However recourse to these principles fails to address the actual contention advanced by the applicant. It is not contended that the Tribunal failed to directly consider a representation or did not actively engage with a representation, rather it is contended that the consideration which the Tribunal did give to the screening tool proceeded on a misunderstanding with the consequence that the state of satisfaction was vitiated.
39 The fundamental difficulty with the argument advanced by the applicant under ground 1 however, is that it has not been demonstrated how a misunderstanding of the true nature of a piece of evidence, which could not have been ascertained on the material before it, could amount to an Avon Downs error. As Derrington J observed in his Honour's comprehensive review of jurisdictional fact review in EHF17 v Minister for Immigration and Border Protection [2019] FCA 1681; (2019) 272 FCR 409 (at [67], [69]-[70] and [76]):
67 Secondly, the various states of mind on which powers are frequently conditioned are concerned with matters which contain inherent value judgments or are dependent upon conclusions about the existence or otherwise of matters which require an assessment of the available material. Necessarily, evaluative judgments are matters on which reasonable minds might differ and may include a not insignificant subjective element: Secretary of State for Education and Science v Tameside Metropolitan Borough Council [1977] AC 1014; Avon Downs Pty Ltd v Federal Commissioner of Taxation (1949) 78 CLR 353 (Avon Downs) at 360. In this way the legislature implicitly recognises that there is no absolute conclusion or state of mind which might be reached in every case. Indeed, usually a range of views might be held, and the power is enlivened if the repository reaches that state of mind on which it is conditioned.
…
69 Fourthly, the danger of an abuse of the court's power of review of administrative action by the frivolous pursuit of unmeritorious proceedings makes it more desirable in the interests of justice and the legal process that the permissible grounds for subjective jurisdictional fact review should be reasonably limited by clear definition and not be left open to a wide range of unfortunate arguments claiming invalidity.
70 Thus, in conformity with the manner in which the legislature has granted power, any review by the Court, as to the existence of a subjective jurisdictional fact must be limited to determining whether the state of mind actually reached is one within the range which the legislature intended to be formed as a pre-requisite to the exercise of power. If there are errors in the process by which a state of mind is reached, such as by considering extraneous or irrelevant considerations or by excluding relevant considerations, the state of mind will not be that which the legislature impliedly requires. Similarly, if, in reaching the state of mind, the repository of power has asked themselves the wrong question as a consequence of a mistake of law, the state of mind is not that on which the exercise of power is conditioned. It might also be noted that the Parliament implicitly intends the requisite state of mind should be one which has been formed logically and rationally upon findings of fact which are logically formed upon probative evidence. Further, even if it cannot be detected that an error occurred in the application of law or consideration of the correct matters, if the conclusion is one which is wholly unreasonable, it can, nevertheless, be inferred that one of the identified error has occurred…
…
76 The precise content of the grounds of irrationality, illogicality or illogical fact finding in reaching or not reaching the required state of satisfaction remains unclear. In S20/2002, Gleeson CJ observed at [9] that to describe a process of reasoning as leading to an illogical conclusion might mean no more than saying that on the same material the reviewer would have reached a different conclusion. The existence of a mere faulty inference of fact will not be sufficient, but, if it can be said that the true and only reasonable conclusion contradicts the one reached, then it may be shown to involve legal error. In that case, McHugh and Gummow JJ were prepared to accept at [37] that the jurisdictional fact did exist because the Tribunal's lack of satisfaction of the protection visa criteria was not illogical or irrational. Their Honours did not specify the scope of the illogicality or irrationality grounds or the ground concerned with evidential deficiency. However, they did refer with some approval to the decision in R v Australian Stevedoring Industry Board; Ex parte Melbourne Stevedoring Company Pty Ltd (1953) 88 CLR 100 (Melbourne Stevedoring) at 119 to the effect that the absence of any foundation in fact is a sufficient ground for vitiating any alleged state of mind which is said to arise from it. Similarly, it was seemingly accepted that inadequacy of material, whilst not in itself sufficient to ground prohibition, may be a circumstance which supports the inference that the repository of power applied the wrong test or was not, in reality, satisfied of the particular matters.
(Emphasis added.)
40 It does not necessarily follow, in my view, as the applicant contends, that the Tribunal's reasons at [112] suggest it was under the impression that there was some subjective evaluation involved in the screening tool assessment. In saying that 'no reasons were given as to how and why that assessment was reached', the Tribunal was correctly referring to an absence of information of any kind. It was an absence of information that would have enabled the Tribunal to determine how much weight to place on the assessment made by the prison assessors because the assessment under the screening tool of being at 'low risk' says nothing about the information provided to the assessors to undertake the assessment or the matters that were relevant to the application of the screening tool or the way in which the screening tool converted those matters into a score responding to a low risk of reoffending.
41 Although it is true that the Tribunal did not specially identify the screening tool that the prison assessors deployed and did not specifically note the applicant's score of 11 which warranted, under the screening tool, the assessment of a low risk of reoffending, no part of the Tribunal's reasons at [112] displays any irrational or illogical reasoning or findings unsupported by the material before it. A decision-maker's reasons should not be construed minutely and finely with an eye keenly attuned to the perception of error: Minister for Immigration and Ethnic Affairs v Wu Shan Liang [1996] HCA 6: (1996) 185 CLR 259 (at 271-272). Nor can it be said that the material considered by the Tribunal on the question of the risk of reoffending was inadequate. As the subsequent paragraphs of its decision make clear, a substantial amount of other material was considered by the Tribunal, including the extensive evidence of a consultant psychologist.
42 Nor can it be said that the Tribunal completely disregarded the screening tool from its consideration. Rather, it simply expressed concern about the lack of available evidence to substantiate the conclusion that prison assessors reached in applying the screening tool to the applicant and gave it less weight as a result. When considered in this light, ground 1 is an attempt to allege error on the part of the Tribunal by the amount of weight it gave to a piece of evidence in circumstances where the only indication that greater weight should have potentially been given was found in further evidence adduced for the first time in this Court. That is not a permissible course to take in the review of a decision-maker's state of satisfaction.
43 Subject to the requirement that it not make findings which are irrational, illogical, unreasonable or unsupported by evidence, it is a matter for the Tribunal to assess and interpret the material before it and to make findings on the basis of that material. While the applicant is at pains to point out that the case is not one of failure to consider the material, but rather, a failure to understand it, that is simply another way of saying that the Tribunal may have arrived at a different conclusion if it had a clear understanding of the particular evidence. It was for the applicant to present the evidence and the case he sought to make to the Tribunal. It is not apparent that the applicant made the issues which are the subject of the additional evidence sought to be adduced on this review, clear to the Tribunal (i.e. the nature of the screening tool and how it is applied and used). In this case, it is clear the Tribunal did engage in detailed consideration of the primary consideration of the protection of the Australian community, as it was required to do and did so over 90 paragraphs of its decision. Clearly it gave careful and detailed consideration to the likelihood of the applicant engaging in further criminal conduct.
44 Further, the Tribunal's conclusion (at [132]) that any likelihood of reoffending would be unacceptable is not shown to be erroneous, nor could any misunderstanding of the screening tool have influenced the Tribunal's separate consideration of the nature and seriousness of any potential harm, if the applicant did reoffend. As no error in the Tribunal's treatment of the screening tool has been demonstrated, it is unnecessary to consider this argument any further.
