Did the Tribunal fall into jurisdictional error by failing to consider Dr Pattni's opinion concerning the effect of visa refusal on the children (ground 2(a))?
59 Mr Khalil submitted that the Tribunal failed to have regard to the evidence in Dr Pattni's report concerning the risk of behavioural or emotional disorders in children where the father is incarcerated; the risks to the children in the present case owing to their mother's medical condition; the risks posed by the absence of support from the extended family; the "unanimous research findings" about the internalisation of "at risk" behaviours where a mother is critically unwell and the father absent; and the "mental health burden and unfavourable consequences" of Mr Khalil's deportation on the children.
60 The obligation of the Tribunal imposed by s 43(2B) of the AAT Act is to set out its findings on questions of fact it considers material, together with the evidence and other material on which those findings are based. That means that a court is generally entitled to infer that any matter not mentioned in the reasons "was not considered by the Tribunal to be material" to its review: Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323 at 346 (McHugh, Gummow and Hayne JJ). In Minister for Immigration and Border Protection v SZSRS [2014] FCAFC 16; 309 ALR 67; 309 ALD 67 (Katzmann, Griffiths and Wigney JJ) at [34] the Full Court observed that:
The fact that a matter is not referred to in the tribunal's reasons, however, does not necessarily mean the matter was not considered by the tribunal at all: [Minister for Immigration and Citizenship v SZGUR (2011) 241 CLR 594] at [31]. The tribunal may have considered the matter but found it not to be material. Likewise, the fact that particular evidence is not referred to in the tribunal's reasons does not necessarily mean that the material was overlooked. The tribunal may have considered it but given it no weight and therefore not relied on it in arriving at its findings of material fact. But where a particular matter, or particular evidence, is not referred to in the tribunal's reasons, the findings and evidence that the tribunal has set out in its reasons may be used as a basis for inferring that the matter or evidence in question was not considered at all. The issue is whether the particular matter or evidence that has been omitted from the reasons can be sensibly understood as a matter considered, but not mentioned because it was not material. In some cases, having regard to the nature of the applicant's claims and the findings and evidence set out in the reasons, it may be readily inferred that if the matter or evidence had been considered at all, it would have been referred to in the reasons, even if it were then rejected or given little or no weight: [Minister for Immigration and Border Protection v MZYTS [2013] FCAFC 114] at [52].
61 With respect to the first aspect, the subject of particular (a), three preliminary observations should be made.
62 First, the Tribunal did say in its reasons that it had taken Dr Pattni's report into account (at [38]). Second, the Tribunal also concluded at [53] that "[n]ot having their father present in their lives will have a negative impact on the children". Third, Dr Pattni did not take into account a number of matters mentioned by the Tribunal in its reasons, such as the older child having been present at the scene of Mr Khalil's assault on his mother, the breakdown of Mr Khalil's second marriage or the mother's attempt to prevent Mr Khalil having access to the children (presumably because she was not told about them).
63 Read in context, however, the first statement related to Dr Pattni's evidence touching on the risk of reoffending. The conclusion that the absence of Mr Khalil would have a negative impact on the children was made without reference to Dr Pattni's opinion and there is nothing in the reasons to indicate that the Tribunal had regard to that opinion in reaching that conclusion. Finally, the matters mentioned by the Tribunal might well affect the weight the Tribunal might attach to Dr Pattni's opinion, but they tell us nothing about whether the Tribunal considered the opinion at all.
64 Having regard to the nature of Mr Khalil's claims and the findings and evidence set out in the Tribunal's reasons, it can be readily inferred that, if Dr Pattni's evidence on this subject had been considered, the Tribunal would have addressed it in its reasons, even if it were then to be rejected or given little or no weight. If consideration had been given to that evidence, at the very least one would expect a reference to her report in this context. After all, the report dealt with her opinion on two subjects, both primary considerations. Yet the Tribunal only adverted to her opinion on one of them. Even on a beneficial interpretation of the Tribunal's decision read as a whole, the compelling inference is that the Tribunal overlooked the evidence.
65 The more difficult question is whether the failure to consider the evidence amounted to a jurisdictional error.
66 Dr Pattni's opinion was to the following effect. It is well established that behavioural or emotional disorders in children are associated with "paternal incarceration" and the children are at greater risk if their father were to be deported (the likely outcome of refusing a visa on character grounds). The situation would become worse if their mother's health deteriorated. There is little other family support having regard to the ill-health of the maternal grandmother and the fact that Mr Khalil's family lives in Egypt. Dr Pattni went on to say:
• There is an undisputed understanding in the research of child development that any trauma - especially separation anxiety and absence of critical parental figure puts the children at added risk of developmental problems.
• Given the complexity of the situation (noted above), these young boys are already predisposed to a wide array of risk factors for problem behaviours that emerges from the literature of several factual circumstances that can have an undisputed impact on their future development and in particular their mental health wellbeing.
• There are unanimous research findings that can support the internationalization of behavioural problems (at risk behaviours - such as aggressive and rule-breaking behaviour) with mothers who may be critically unwell and with the absence of the father.
• Undisputed evidence children in studies on deportation of the father highlight the associated mental health burden and the unfavourable consequences related to their children. Both the long term and short-term impact on mental health, social and economic has been established.
• The future of these children is of critical concern given the mother's ability to meet the complex emotional, financial, social, and psychological needs given her medical condition.
• School participation may also negatively be impacted and experiences of mental health symptoms post-parental deportation (i.e., persistent crying, depression, sadness, anger, resentment).
67 The Minister submitted that the Tribunal accepted that Mr Khalil would play a positive role in his children's lives and contended, in effect, that it was unnecessary for the Tribunal to repeat the detail of Dr Pattni's evidence. The Minister argued that the finding of the Tribunal could not have been more favourable to Mr Khalil, particularly in the face of the submission he (the Minister) had made to the Tribunal that Mr Khalil was unlikely to play a positive parental role in the future because of the risk he might reoffend.
68 The difficulty with this submission is twofold. First, it did not grapple with the evidence itself, which was concerned with the potential impact on the children of an adverse decision - children who are already likely to have been traumatised by their separation from their father during his imprisonment and, one would infer, his absence in immigration detention. Second, while the Tribunal did find, contrary to the Minister's submission, that Mr Khalil would play a positive role in his children's future, the failure of the Tribunal to consider Dr Pattni's opinion may have caused the Tribunal to put less weight on the best interests of the children than it might have done had it taken that opinion into account.
69 Of course, ignoring material relevant only to fact-finding does not of itself give rise to jurisdictional error: Minister for Immigration and Citizenship v SZRKT (2013) 212 FCR 99 at [97]. As we have already observed, it was not necessary for the Tribunal to refer to every piece of evidence. Moreover, there is a distinction between a failure by the Tribunal to advert to evidence which, if accepted, might have caused it to come to a different finding of fact and a failure by the Tribunal to address a contention which, if accepted, might establish the elements of a statutory claim: WAEE at [44]-[46].
70 In determining whether it is a jurisdictional error to fail to consider certain evidence, "the fundamental question must be the importance of the [evidence] to the exercise of the Tribunal's function and thus the seriousness of any error": SZRKT at [111] (Robertson J), endorsed by the Full Court in Minister for Immigration and Border Protection v MZYTS (2013) 230 FCR 431 at [70] (Kenny, Griffiths and Mortimer JJ). Moreover, "it is important not to reason that because a failure to deal with some (insubstantial or inconsequential) evidence will, in some circumstances, not establish jurisdictional error, then a failure to deal with any (substantial and consequential) evidence will also not establish jurisdictional error": SZRTK at [111].
71 In our opinion, the evidence of Dr Pattni concerning the potential harm to the children arising from indefinite separation from their father was not insubstantial or inconsequential evidence, even if it the Tribunal might ultimately have accorded it little weight. The Tribunal ought to have taken it into account because it was expert evidence going to a consideration to which the Tribunal was bound to have regard.
72 Whether or not the error is jurisdictional also depends on whether the evidence is material, that is to say, whether there is a realistic possibility the outcome could have been different had the Tribunal taken it into account: SZMTA at [4], [45] (Bell, Gageler and Keane JJ). In determining the answer to that question, the remarks made in Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs v FAK19 [2021] FCAFC 153 at [174] (Kerr and Mortimer JJ, Allsop CJ agreeing at [1]) must be borne in mind:
This Court cannot substitute itself in the undertaking of such an evaluative task. In undertaking an assessment on materiality, where there are reasonable and rational choices to be made in fact finding, it is not appropriate for the supervising court to attempt to place itself in the mind of the Tribunal, and speculate about what would or could have changed a particular Tribunal's mind. To do so brings the court into the merits of the decision. Rather, the supervising court must assume a Tribunal acting fairly and reasonably, with a mind open to persuasion, would give active and genuine consideration to all matters relevant to its review, including the matter which was erroneously omitted, or misconceived, and which caused it to exceed its jurisdiction. See generally Martincevic v Commonwealth [2007] FCAFC 164; 164 FCR 45 at [67]-[68], Chamoun v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCAFC 66; 276 FCR 75 at [70]; PQSM v Minister for Home Affairs [2020] FCAFC 125; 279 FCR 175 at [69]-[73].
73 Although the Tribunal might ultimately have placed little weight on Dr Pattni's evidence for any one of a number of reasons, "a Tribunal acting fairly and reasonably, with a mind open to persuasion", could conceivably have come to a different conclusion if it had taken the evidence into account. That is because the evidence could have affected the weight it attached to the primary consideration of the best interests of the children and therefore the weight it attached to the other considerations: cf. Dunasemant v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2022] FCAFC 13 at [60] (Davies, Rangiah and Cheeseman JJ). By failing to take it into account, the Tribunal failed to complete its statutory task and so fell into jurisdictional error.
74 It follows that ground 2(a) of the amended notice of appeal is made out.
