The first ground of review: the best interests of minor children
18 By his first ground of review, the applicant contends that the Tribunal's decision was affected by jurisdictional error because it asked itself the wrong question, reasoned in an illogical or irrational way and/or relied on unwarranted assumptions. More specifically, the applicant makes several principal criticisms of the Tribunal's reasoning in relation to considering the best interests of minor children. It is convenient to consider each in turn.
19 First, the applicant submits that although the Tribunal found (at [118]) that the applicant and MX have a significant relationship and that there is a prospect it would continue if he were released into the community, it found that there is insufficient evidence to make definitive determinations about the effect on each of the identified minor children if the applicant was deported. It is said that in making that finding, the Tribunal did not distinguish between the earlier findings it had made in relation to the applicant's relationship with MX and the other children.
20 The applicant rightly acknowledges that, as it was put in Minister for Immigration and Ethnic Affairs v Wu Shan Liang [1996] HCA 6; 185 CLR 259 at 272, "the reasons of an administrative decision-maker are meant to inform and not to be scrutinised upon over-zealous judicial review by seeking to discern whether some inadequacy may be gleaned from the way in which the reasons are expressed." Naturally, that caution has its limits as the Court has only the decision-maker's reasons to understand just what it has done. See Ballas v Dept of Education (State of NSW) [2020] NSWCA 86; 102 NSWLR 783 at [79].
21 To my mind, the applicant's first criticism of the Tribunal's decision falls foul of the Wu Shan Liang caution. It is not inconsistent to find that the applicant and MX have a significant relationship, and to find that there is insufficient evidence to make a definitive determination about the effect on MX if the applicant were deported. It was open to the Tribunal to reach the same conclusion with regard to the insufficiency of evidence without distinguishing between each child, or between MX and the others.
22 This is particularly so where there was no evidence addressed to the likely effect that the applicant's deportation would have on any of the children. There was more evidence about the applicant's interactions with and care of MX than there was in relation to the other children, which is what enabled the findings about the relationship with MX being good and significant, but the evidence went no further. It was open to the Tribunal to find, as it did, that it could not make "definitive determinations" about the effect on each of the children, including MX, if the applicant was deported.
23 Secondly, the applicant submits that in concluding that the primary consideration in question weighs very slightly in favour of revoking the cancellation of the visa, "mainly because of the generally peripheral role PCYS has had in the lives of any of the relevant minor children in Australia", the Tribunal treated the children "globally" without drawing a distinction between the role the applicant has had in the life of MX and his role in relation to the other children. He submits that that is inconsistent with the earlier finding that the applicant has had "a significant relationship" with MX.
24 Similarly, I do not see that it is inconsistent to conclude that the applicant has a significant relationship with MX and at the same time to conclude that he generally has a peripheral role in MX's life; the nature of a relationship between an adult and a child and the role played by the adult in the life of the child are not necessarily coextensive. The applicant's difficulty in this regard, which is not uncommon in cases such as this, is that for much of MX's young life, the applicant has been either in prison or in immigration detention. That necessarily limits the role that he can have played in MX's life, and it leaves any future role uncertain including because of his mother's position that the applicant should play no role if his illicit drug use continues or resumes.
25 The applicant relies on s 8.3(3) of Direction 90 on this point, and in particular its requirement that the best interests of each child should be given individual consideration to the extent that their interests may differ - the applicant submits that this means that MX's interests had to be considered separately from the other children because his interests differ. However, their individual interests had to be considered separately only "to the extent that" they differ, and the Tribunal's view was that in relation to the role played by the applicant in the lives of the children their interests did not differ. That approach was open to the Tribunal. Also, this case is different from RGCZ v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2022] FCAFC 201 at [54], relied on by the applicant, because of the Tribunal's finding that the role of the applicant in the lives of the relevant children did not relevantly differ - there was therefore no requirement to assess their interests individually.
26 Thirdly, the applicant submits that although the Tribunal found (at [119]) that the primary consideration in question weighed only "very slightly" in favour of revocation, the Tribunal then clarified the basis for that finding by adding that some weight does attach to it "because although there has been no relationship between PCYS and his biological son, AZ, thus far, the removal of the Applicant from Australia would effectively prevent the prospects of one ever developing." That is to say, the applicant submits that what weight was ascribed to the consideration was so ascribed because of the applicant's potential relationship with his biological son, and no significance was given to his relationship with MX notwithstanding the earlier findings that they have a good and significant relationship.
27 It is notoriously a matter for the Tribunal what weight to ascribe to any particular consideration. It is to read [119] of the Tribunal's reasons too critically to read it as saying that the only reason why any weight attaches to the consideration is because of the possibility of a relationship developing between the applicant and his son, AZ. Reading [118] and [119] together, and fairly, it is apparent that the Tribunal took account of its finding of the relationship between the applicant and MX being "significant", and included that in its conclusion with regard to the consideration in question ultimately weighing only "very slightly" in favour of revocation.
28 The applicant submits that it is not to be overly critical of the Tribunal to read [119] in the way he contends for because that meaning is simply based on the ordinary meaning of the words employed by the Tribunal; he says that the ordinary meaning of the words employed in [119] is that the only reason any weight was ascribed to the best interests of minor children consideration was because of the prospective relationship with AZ, the necessary implication being that no weight was given to the relationship with MX. There are two reason why I do not think that is right. First, the Tribunal expressly mentioned the relationship with MX in [118], which forms part of its consideration of and conclusions on the question of the interests of minor children, from which I would readily infer that the Tribunal took that relationship into account in the very next paragraph when ascribing weight to the consideration in question. Secondly, the Tribunal apparently did not particularly distinguish between weight described variously as "very slightly" and "some" (in [119]) and "not strong" (in [157]); that is to say, not too fine a point can be made about the Tribunal's use of "very slightly" and "some" in [119].
29 Fourthly, the applicant submits that in finding that he does not have a parental role in relation to any of the children (at [118]), the Tribunal did not draw a distinction between the role the applicant has played in the life of MX and the nature of his relationship with the other affected children. It is said that that is notwithstanding the applicant's unchallenged evidence that he regarded himself as a father to MX.
30 It is inherent in the impugned reasoning of the Tribunal that it did not regard the applicant to have a parental relationship with MX. Although the applicant had himself said that he regarded himself as a father to MX, MX's mother did not characterise the relationship in that way, and there was no other evidence in support of it being so characterised. MX's mother, in answer to the question what the applicant's relationship is like with her two sons, said "Like uncle, like brother, like uncle, family member." In those circumstances, the Tribunal was not bound to accept the applicant's characterisation. It was open to the Tribunal to regard his relationship with the children, other than AZ, as "avuncular".
31 Fifthly, the applicant submits that it was illogical for the Tribunal to limit its consideration of the best interests of the children if the applicant were deported, and not to consider their interests if the applicant remained in detention.
32 The submission arises from the fact that the Tribunal considered the effect on the applicant if he were to remain in detention for a long period of time, particularly considering that he is a citizen of Afghanistan and it was submitted that there would be some difficulty deporting him to Afghanistan. It was within the zone of discretion of the Tribunal to give consideration to that matter, which the Tribunal found weighed strongly in the applicant's favour, ie, in favour of revocation. However, there was no obligation on the Tribunal to consider the likely effect on minor children in Australia if the applicant were to remain in immigration detention for a lengthy period of time.
33 In that regard, the requirement in Direction 90 is that the Tribunal make a determination about whether non-revocation is, or is not, in the best interests of a child "affected by the decision". The ordinary consequence of non-revocation is deportation, as required by s 198 of the Migration Act. Indeed, the Minister is under an obligation to remove an unlawful non-citizen as soon as reasonably practicable: Al-Kateb v Godwin [2004] HCA 37; 219 CLR 562. Nevertheless, as the cases demonstrate, all too often unlawful non-citizens remain in immigration detention semi-indefinitely. Such a circumstance is, however, likely to be less detrimental to the interests of minor children in Australia than deportation because the possibility of visits and physical presence in Australia provide greater opportunity for an ongoing relationship. There was therefore nothing illogical in the Tribunal not considering the interests of the minor children if the applicant was to face a lengthy period in immigration detention rather than being deported relatively soon.
34 It is to be borne in mind that there was no finding that the applicant would likely face a lengthy period in immigration detention, and no submission was addressed to the Tribunal on the relevant minor children being differently affected by the applicant's lengthy detention as opposed to deportation. The only submission identified by the applicant as relevant is that it was put on his behalf to the Tribunal that "while it's true that he could call on a phone if he were to remain in detention or if he were removed to Afghanistan, it's clearly not the same thing as being a present and hands-on older uncle, which is what he wants to be and which [MX] has also expressed a desire to see him in person." The distinction drawn there is between detention or removal, on the one hand, and release on the other. In the absence of any clearly articulated submission, there was no obligation on the Tribunal to consider the effect on the children of the applicant's possible lengthy detention separately from deportation.
35 Finally, the applicant submits that in its finding (at [111]) that the applicant did nothing to establish contact with his son, AZ, in the six year period since learning of his birth, the Tribunal impermissibly approached the question of AZ's interests from the perspective of the applicant and his conduct in relation to AZ and not from the perspective of AZ. The applicant submits that this is contrary to the requirement of Direction 90, particularly as recognised in Gage v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCA 1298 at [53] per Abraham J.
36 The finding in question is directed to the principal issue with regard to the position of AZ, namely the prospects of the applicant establishing a relationship with AZ if the cancellation of his visa is revoked. That was the principal issue because the applicant has no pre-existing relationship with AZ, never having had any contact with him. What effort the applicant has made in the past to establish contact with AZ is clearly relevant to that issue. The finding in question was made not to disadvantage AZ by identifying criticism of the applicant, or to approach matters from the perspective of the applicant, but to assess the prospects of a relationship in the future. AZ being a minor, those prospects necessarily depend on the applicant's commitment to a relationship. The criticism of the Tribunal in this respect is therefore unfounded.
