Consideration
55 In Muggeridge v Minister for Immigration and Border Protection (2017) 255 FCR 81, a Full Court of this Court (Flick, Perry and Charlesworth JJ) considered whether the decision made by the Minister in that case to cancel Mr Muggeridge's visa under s 501(2) of the Act was legally unreasonable. At [35] the Full Court summarised the applicable principles as follows:
The alleged error is one affecting the process of reasoning adopted by the Minister in the exercise of a discretionary power. It is well settled that a discretionary power conferred by a statute is to be construed as subject to the condition that it be exercised reasonably. The principles to be applied are considered at length in the various judgments in Minister for Immigration and Citizenship v Li (2013) 249 CLR 332 (Li) and in the decisions of the Full Court of this Court in Minister for Immigration and Border Protection v Eden (2016) 240 FCR 158 and Minister for Immigration and Border Protection v Stretton (2016) 237 FCR 1 (Stretton). They may be briefly summarised as follows:
(1) the power conferred under s 501(2) of the Act is implicitly confined by the subject matter, scope and purpose of the legislation: Water Conservation and Irrigation Commission (NSW) v Browning (1947) 74 CLR 492 at 505 (Dixon J);
(2) as Allsop CJ explained in Stretton (at [11]), the task of reviewing a decision for legal unreasonableness is not definitional, but one of characterisation:
… the decision is to be evaluated, and a conclusion reached as to whether it has the character of being unreasonable, in sufficiently lacking rational foundation, or an evident or intelligible justification, or in being plainly unjust, arbitrary, capricious, or lacking common sense having regard to the terms, scope and purpose of the statutory source of the power, such that it cannot be said to be within the range of possible lawful outcomes as an exercise of that power. …
(3) the Court is to look to the reasons given for the decision to understand why the power was exercised as it was: Minister for Immigration and Border Protection v Singh (2014) 231 FCR 437 (Singh);
(4) as the Full Court explained in Singh, the process of review of legal unreasonableness "will inevitably be fact dependent". The Court continued (at [48]):
… That is not to diminish the importance of the supervising court maintaining an approach which does not involve the substitution of its own judgment for that of the decision-maker. Rather, it is to recognise that any analysis which involves concepts such as "intelligible justification" must involve scrutiny of the factual circumstances in which the power comes to be exercised.
(5) in a different review context, Deane J spoke of the requirement that a statutory tribunal act rationally and reasonably: Australian Broadcasting Tribunal v Bond (1990) 170 CLR 321 at 367-368. His Honour's explanation of the content of that obligation applies equally to the Minister in the exercise of the power conferred by s 501(2) of the Act (at 367):
When the process of decision-making need not be and is not disclosed, there will be a discernible breach of such a duty if a decision of fact is unsupported by probative material. When the process of decision-making is disclosed, there will be a discernible breach of the duty if findings of fact upon which a decision is based are unsupported by probative material and if inferences of fact upon which such a decision is based cannot reasonably be drawn from such findings of fact.
(6) nevertheless, as Wigney J said (with respect correctly) in Minister for Immigration and Border Protection v SZUXN (2016) 69 AAR 210 (at [55]):
… allegations of illogical or irrational reasoning or findings of fact must be considered against the framework of the inquiry being whether or not there has been jurisdictional error on the part of the Tribunal: SZRKT at 137 [148]. The overarching question is whether the Tribunal's decision was affected by jurisdictional error: SZRKT at [151]. Even if an aspect of reasoning, or a particular factual finding, is shown to be irrational or illogical, jurisdictional error will generally not be established if that reasoning or finding of fact was immaterial, or not critical to, the ultimate conclusion or end result: Minister for Immigration and Citizenship v SZOCT (2010) 189 FCR 577 at [83]-[84] (Nicholas J); SZNKO v Minister for Immigration and Citizenship (2013) 140 ALD 78 at [113]. Where the impugned finding is but one of a number of findings that independently may have led to the Tribunal's ultimate conclusion, jurisdictional error will generally not be made out: SZRLQ v Minister for Immigration and Citizenship (2013) 135 ALD 276 at [66]; SZWCO at [64]-[67].
56 In Minister for Immigration v Stretton (2016) 237 FCR 1 at [4] and [6]-[12] Allsop CJ said:
[4] In Minister for Immigration and Citizenship v Li (2013) 249 CLR 332, the High Court made clear that legal reasonableness or an absence of legal unreasonableness was an essential element in the lawfulness of decision-making; Parliament is taken to intend that statutory power will be exercised reasonably: see Li at [26] and [29] (French CJ), [63] (Hayne, Kiefel and Bell JJ) and [88] (Gageler J).
…
[6] Each of the judgments in Li sought to give explanatory content to the concept of legal unreasonableness. As was discussed in Minister for Immigration and Border Protection v Singh (2014) 231 FCR 437, the judgments in Li identified two different contexts in which the concept of legal unreasonableness was employed: a conclusion after the identification of jurisdictional error for a recognised species of error, and an "outcome-focused" conclusion without any specific jurisdictional error being identified: Singh at [44].
[7] It is in relation to the second context, the "outcome-focused" application of the concept, that precise definition, beyond explanation of the operative notion and of the legal technique by which to make the assessment, becomes productive of complexity and confusion. There is "an area of decisional freedom" of the decision-maker, within which minds might differ. The width and boundaries of that freedom are framed by the nature and character of the decision, the terms of the relevant statute operating in the factual and legal context of the decision, and the attendant principles and values of the common law, in particular, of reasonableness. The boundaries can be expressed by the descriptions and explanatory phrases of the kind set out in [5] above.
[8] The content of the concept of legal unreasonableness is derived in significant part from the necessarily limited task of judicial review. The concept does not provide a vehicle for the Court to remake the decision according to its view as to reasonableness (by implication thereby finding a contrary view unreasonable). Parliament has conferred the power on the decision-maker. The Court's function is a supervisory one as to legality: see Li at [30], [66] and [105].
[9] The conclusion that a decision is legally unreasonable by reference to the outcome, whether or not there are reasons therefor, is assisted by reference to expressions taken from cases such as those mentioned in [5] above. Any criticism that these explanations are circular and vague is to be met by attending to the terms, scope and policy of the statute and the values drawn from the statute and the common law that fall to be considered in assessing the decision. The terms, scope and policy of the statute and the fundamental values that attend the proper exercise of power - a rejection of unfairness, of unreasonableness and of arbitrariness; equality; and the humanity and dignity of the individual - will inform the conclusion, necessarily to a degree evaluative, as to whether the decision bespeaks an exercise of power beyond its source.
[10] This concept of legal unreasonableness is not amenable to minute and rigidly-defined categorisation or a precise textual formulary. For instance, in argument, the submission was put that [76] of Li in the judgment of Hayne, Kiefel and Bell JJ contained two (different) "tests": (1) if upon the facts the result is unreasonable or plainly unjust and (2) if the decision lacks an evident and intelligible justification. The submission reflected the dangers of overly emphasising the words of judicial decisions concerning the nature of abuse of power, and of unnecessary and inappropriate categorisation. The plurality's discussion of unreasonableness at [63]-[76] in Li should be read as a whole - as a discussion of the sources and lineage of the concept: [64]-[65], of the limits of the concept of reasonableness given the supervisory role of the courts: [66], of the fundamental necessity to look to the scope and purpose of the statute conferring the power to find its limits: [67], of the various ways the concept has been described: [68]-[71], of the relationship between unreasonableness derived from specific error and unreasonableness from illogical or irrational reasoning: [72], of the place of proportionality or disproportion in the evaluation: [73]-[74] (as to which see also French CJ at [30] and see also McCloy v New South Wales (2015) 89 ALJR 857; 325 ALR 15 at [3] (French CJ, Kiefel, Bell and Keane JJ)), of the guidance capable of being obtained from recognising the close analogy between judicial review of administrative action and appellate review of judicial discretion: [75]-[76].
[11] The boundaries of power may be difficult to define. The evaluation of whether a decision was made within those boundaries is conducted by reference to the relevant statute, its terms, scope and purpose, such of the values to which I have referred as are relevant and any other values explicit or implicit in the statute. The weight and relevance of any relevant values will be approached by reference to the statutory source of the power in question. The task is not definitional, but one of characterisation: the decision is to be evaluated, and a conclusion reached as to whether it has the character of being unreasonable, in sufficiently lacking rational foundation, or an evident or intelligible justification, or in being plainly unjust, arbitrary, capricious, or lacking common sense having regard to the terms, scope and purpose of the statutory source of the power, such that it cannot be said to be within the range of possible lawful outcomes as an exercise of that power. The descriptions of the lack of quality used above are not exhaustive or definitional, they are explanations or explications of legal unreasonableness, of going beyond the source of power.
[12] Crucial to remember, however, is that the task for the Court is not to assess what it thinks is reasonable and thereby conclude (as if in an appeal concerning breach of duty of care) that any other view displays error; rather, the task is to evaluate the quality of the decision, by reference to the statutory source of the power and thus, from its scope, purpose and objects to assess whether it is lawful. The undertaking of that task may see the decision characterised as legally unreasonable whether because of specific identifiable jurisdictional error, or the conclusion or outcome reached, or the reasoning process utilised.
57 The resolution of this ground requires first a consideration of what the Tribunal found at [185] of its decision record. There the Tribunal said:
The Tribunal finds that despite the support of his family in Nigeria, the Applicant will face practical, financial and emotional hardship upon return, due to his separation from his wife and stepson, lack of social, medical and economic support and his expressed fear of harm on return. The Applicant's hardship will be exacerbated by the negative impacts that relocating to Nigeria would have on his wife and stepson, should they choose to move there if his visa remains cancelled and he must return to Nigeria.
(Emphasis added.)
58 This ground concerns the words emphasised above, namely the Tribunal's finding that "despite the support of his family" Mr Oke "will face …. lack of social, medical and economic support". Mr Oke contended the word "lack" means "no". That is, the relevant finding by the Tribunal at [185] is that he would have no social, medical and economic support.
59 There was disagreement between the parties about the meaning of "lack" in this context. The Shorter Oxford English Dictionary defines "lack" to mean "a shortage or absence" of "something desirable or necessary". The Macquarie Dictionary defines "lack" to mean "deficiency or absence of something requisite, desirable, or customary". It follows that "lack" can mean either a deficiency or absence. In order to understand how the Tribunal used the word "lack" in making its finding at [185], regard must be had to the context in which it made that finding.
60 At [182] the Tribunal found that, while they are limited, Mr Oke will have access to mental health services in Nigeria and that he will have access to health services and treatment although the standard and ease of access may not be of the same standard as in Australia. At [183] of its decision record the Tribunal considered whether Mr Oke would face any language or cultural barriers upon return to Nigeria as required by cl 14.5(1)(b) of the Direction 79 and at [184] the Tribunal considered Mr Oke's former employment, his skills and the support that could be provided by his family as required by cl 14.5(1)(c) of Direction 79. Those findings necessarily provide context for the findings at [185].
61 That being so, it is clear that when the Tribunal said that there would be a "lack of social, medical and social support" it used the word "lack" in the sense of a deficiency rather than an absence or, as Mr Oke submitted, that there would be no such support. Given the anterior finding at [182], that is the way in which the Tribunal's finding ought to be interpreted. The findings at [182] and [185] of the Tribunal's decision record can be reconciled.
62 On the assumption that the Minster's submission that "lack of" meant shortage, Mr Oke also submitted that there was no evidence to support the finding at [185] of the Tribunal's decision record that he would have a shortage of access to economic support in Nigeria. I reject that submission. First, the finding of lack of economic support, is a finding in favour of Mr Oke. Thus, even if the Tribunal made an error, it is not one about which Mr Oke can complain. Such an error would not be material. Secondly, Mr Oke gave evidence and made submissions to the Tribunal about the financial difficulties he would face if returned to Nigeria. So much is evident from [184] of the Tribunal's decision record. To that end, there was evidence before the Tribunal in relation to Mr Oke's financial circumstances and the hardship he would face. By way of example, in his personal statement, originally provided to the delegate under cover of a letter from his solicitor, Mr Oke said that if he is returned to Nigeria he "will not be able to find work due to the economic crisis" and that he has "no savings".
63 For those reasons Mr Oke's contention that the Tribunal's finding at [185] was legally unreasonable or illogical is not made out and ground 2 must fail.
