The decision below
10 The appellant's application for judicial review (to which this appeal relates) raised two grounds. Only one of those grounds is relevant to this appeal, namely:
The [Tribunal] fell into jurisdictional error by failing to give any, or appropriate, consideration to a relevant consideration, namely cl. 9.2(4) of Direction 79 (Best interests of a child in Australia) by overlooking evidence directly relevant to the effect that separation would have on the [appellant's] daughter.
11 Clause 9.2(4)(d) of Direction 79 provides:
Best interests of minor children in Australia affected by the decision
…
(4) In considering the best interests of the child, the following factors must be considered where relevant:
…
(d) The likely effect that any separation from the non-citizen would have on the child, taking into account the child's or non-citizen's ability to maintain contact in other ways;
12 For the purposes of considering the application of this clause, the Tribunal noted that the appellant had a young child and two young nephews who normally resided with him in Australia. The Tribunal found that the appellant was likely to play a meaningful role in the lives of these children should he be allowed to remain in Australia, including financially and by providing practical and emotional support. It accepted that if the appellant were to be repatriated to India, with his child and nephews remaining in Australia, there would be an adverse impact on their interests. The Tribunal placed substantial weight on that finding as a factor in favour of not exercising the discretion to cancel the appellant's visa.
13 The substance of the appellant's case in relation to this ground was that the Tribunal did not give proper, genuine and realistic consideration to the impact on his child of his (the appellant's) removal from Australia, or engage in an active intellectual process in relation to that matter. The appellant placed particular reliance on a letter that formed part of a large body of documentary material he had placed before the Tribunal. The letter was written by a maternal and child health nurse, Ms McKinnon, in which she said:
My purpose for writing is to support [the appellant's wife] in requesting leniency in her husband's appeal to provide [the appellant's wife] the support she needs for her emotional state and parenting. This is order [sic] will benefit [the appellant's daughter] in this crucial stage of development.
[The appellant's wife] is an isolated first-time mother whose husband is currently in detention with an expired visa due to a criminal conviction. As [the appellant's wife] is on a bridging visa, this leaves the family with no income and an uncertain future. [The appellant's wife's] parents remain in India and her husband's parents are deceased. It is usually the cultural norm in India to have parental and spousal support in caring for an infant. [The appellant's wife] has no transport, and didn't even have a pram for [the appellant's daughter] despite her being 6m old.
(Emphasis in original.)
14 Ms McKinnon performed a test which led her to conclude that the appellant's wife was suffering from severe post-natal depression. The letter noted that:
[The appellant's wife] identifies that her emotional state is a direct result of her husband being in detention. [The appellant's wife] verbalises her perception that she need her husbands [sic] physical presence and support to raise [the appellant's daughter], and that her anxiety over their predicament consumes her every moment.
15 The letter continued:
I am pleased to see that [the appellant's wife] has connected with Psychology services at CBCHS, but remain concerned that [she] continues to suffer significant low moods and anxiety that are influenced by what is an ongoing situation. Research states that the first three years of life are a period of incredible growth in all areas of a baby's development, but also highlights the impact maternal depression and stress can have on an infant's mental health and developing mind. Please refer to https://www.zerotothree.org/early-development/infant-and-early-childhood-mental-health. [The appellant's daughter] demonstrated signs of anxiety, in that she is very stranger wary, described as waking frequently and relying on breast-feeding to pacify and sleep. I have not observed [the appellant's daughter] to smile in my three visits to the family so far.
16 Before the primary judge, the appellant contended that the Tribunal's reasoning did not disclose any, or any sufficient, engagement with the concerns that Ms McKinnon had raised in the letter. He contended that if the Tribunal had given proper, genuine and realistic consideration to the psychological impact that separation from the appellant would have on his child, it may have reached a different conclusion.
17 The primary judge rejected that contention. In order to put his Honour's reasons in context, it is necessary to note the following paragraphs from the Tribunal's Decision Record.
18 At [80], the Tribunal said:
80. In relation to Mr Singh's biological child, the Tribunal has proceeded on a worst case premise that if his wife's pending visa application is approved, there is the potential at least that she and her child will remain in Australia. The Tribunal accepts that Mr Singh's wife is suffering depressive symptoms as a first-time mother, while concurrently dealing with the prolonged uncertainty surrounding Mr Singh's visa status. Both she and her child are reliant on Mr Singh and Mr Singh's sister. Under such circumstances, Mr Singh's repatriation would be adverse to the child's best interests, including by losing the financial, emotional and practical support Mr Singh could provide. Maintaining a close father-child relationship would also be very difficult if Mr Singh was returned to India. Alternatives to physical contact are clearly suboptimal. If on the other hand it were still the intention of Mr Singh's wife that she and her child accompany Mr Singh back to India, a direct parental relationship by both parents could be maintained.
19 At [82] - [83], it said:
82. Notwithstanding the uncertainty regarding the visa status of Mr Singh's wife and child, the intentions of Mr Singh's wife in the event that Mr Singh was repatriated, and the extent to which Mr Singh's brother-in-law will remain engaged with his children after separating from Mr Singh's sister last May, the Tribunal accepts it is in the best interests of Mr Singh's biological child and his nephews that he remains in Australia.
83. The Tribunal places substantial weight on this primary consideration in favour of not exercising the discretion to cancel Mr Singh's visa.
20 At [127], the Tribunal said:
127. Notwithstanding the uncertainty surrounding the visa status of Mr Singh's wife and child, and the extent to which his former brother-in-law will continue to perform a parental role for Mr Singh's nephews, the Tribunal concludes it is in the Best interests of children in this matter for Mr Singh to remain in Australia. The Tribunal places substantial weight on this primary consideration in favour of not exercising the discretion to cancel his visa.
(Emphasis in original.)
21 At [129], the Tribunal said:
129. Having examined the factors for and against visa cancellation individually and cumulatively, the weight of evidence supports a finding that the discretion under section 501(2) of the Act to cancel Mr Singh's visa should be exercised. That is because the primary considerations 'Protection of the Australian community' and 'Expectations of the Australian community' weigh substantially against Mr Singh's application. These outweigh the collective weight of the primary consideration 'Best interests of minor children in Australia,' which weighs substantially in Mr Singh's favour, 'Strength, nature and duration of ties,' which weighs moderately in Mr Singh's favour, and 'Extent of Impediments if removed,' which weighs slightly in favour of Mr Singh.
22 The primary judge gave three reasons for rejecting this ground of review:
70. First, Ms McKinnon's letter was primarily directed to the effect on the applicant's wife of her separation from the applicant, the isolation she has suffered as a result of his detention, her postnatal depression, and the effect those matters are likely to have on their child. Those matters were considered by the Tribunal. The Tribunal accepted (at [80]) that the applicant's wife was suffering from postnatal depression while concurrently dealing with the prolonged uncertainty surrounding the applicant's visa status. It accepted that cancellation of the applicant's visa would "be adverse to the child's best interests including by losing the financial, emotional and practical support [the applicant) could provide". Importantly, it accepted (at [82]-[83] and [127]) that it is in the best interests of the applicant's child that the applicant remains in Australia and placed "substantial weight" on that primary consideration in favour of not exercising the discretion to cancel the applicant's visa.
71. Second, it is not appropriate to infer that the Tribunal overlooked Ms McKinnon's letter or did not properly take it into account when in its reasons the Tribunal specifically noted (at 24) that the letter was in evidence, briefly summarised the letter, and noted (at [80]) that the applicant's wife is "suffering depressive symptoms as a first-time mother" which information came from the letter. The letter was a single page in over 1,000 pages of material filed in the Tribunal, and the applicant did not call Ms McKinnon to give evidence; he did not refer to the letter in submissions; and he placed no weight on the letter during the Tribunal hearing. It is appropriate to infer that the applicant's choice as to the conduct of his case and the material that he took the Tribunal to was reflected in the extent to which the Tribunal referred to the letter. The Tribunal was not required to refer in the reasons for decision to every piece of evidence and every contention made by an applicant: Carrascalao at [45].
72. Third, if contrary to my view it is accepted that the Tribunal failed to give the matters set out in Ms McKinnon's letter proper, genuine and realistic consideration to the extent required by cl. 9.2(4) of Direction 79, the applicant failed to demonstrate that such an error was material in the sense that it deprived the applicant of a realistic possibility of a different outcome: Hossain v Minister for Immigration and Border Protection [2018] HCA 34; (2018) 264 CLR 123 at [25] and [30] (Kiefel CJ, Gageler and Keane JJ). The Tribunal found that cancellation of the applicant's visa was not in the best interests of his young child and gave "substantial weight" to that factor in favour of not exercising the discretion to cancel the applicant's visa. But, having examined the factors for and against visa cancellation, the Tribunal concluded (at [129]) that the protection of the Australian community against a low but nevertheless real and unacceptable risk that the applicant would reoffend, and the expectations of the Australian community that has a "particularly low" tolerance for sexual crimes against children, outweighed the best interests of any minor children in Australia. If (contrary to my view) the Tribunal failed to give appropriate consideration to the letter, I am not persuaded that such a failure deprived the applicant of a realistic possibility of a different outcome.
