Ground 2
91 The parties were largely in agreement as to the applicable principles. The Minister accepted that the summary in Navoto at [84]-[89] outlined accurately the various species of error that may infect decision-making in the present context. The dispute between them is whether any of those errors occurred in this case.
92 That dispute raises two principal factual questions concerning:
(a) the content of the applicant's s 501CA(4)(a) representations; and
(b) the AAT's consideration of the applicant's s 501CA(4)(a) representations and the issue of financial support.
93 In my view, there is sufficient evidence to support the applicant's submission that the applicant's s 501CA(4)(a) representations included a claim that failure to revoke cancellation would adversely affect his family, and his minor Australian step-children through his reduced ability to make financial contributions. That evidence includes:
(a) The applicant's response to the question "Please describe the impact the cancellation of the your visa would have, or has had, on your partner", contained in the a personal circumstances form provided in response to the notice of visa cancellation under s 501(3A):
The impact of the cancellation of my visa to my wife (sic). She will face more financial difficulty. The bills, rent and specially the welfare of our kids. It will be very hard for her. It will effect her (sic) terribly bad.
(b) The applicant's response to the question "Please describe the impact the cancellation of our visa would have, or has had, on your family", also contained in the personal circumstances form:
It will affect them financially. I got a permanent job. I contribute a lot in paying the bill, food, rent and etc.
(c) A supporting letter from the applicant's wife, Ms Fernando, provided to the Minister's delegate in which she said:
[The applicant] has been supporting me and my 5 kids financially since our marriage.
(d) A supporting letter from the applicant's wife, Ms Fernando, provided to the AAT in which she said (emphasis in original):
I have been facing financial problems with our situation where money worries are causing my (sic) stress and it's impact to my mental health due to all our bills and payments that used to be taken care of by my husband even though he stays in his own place. (attached or (sic) some of our outstanding bills that needed to be taken care of when my husbands (sic) comes home)…
94 The second factual question is more difficult. The AAT's reasons on this matter are ambiguous. The relevant passages are at [52], [70] and [72] of the AAT's reasons:
[52] …The Tribunal is also prepared to accept that the applicant provided financial support to the family while he was employed and his evidence is that his wife visited him in detention and took some of his savings. However, there is limited probative evidence of any ongoing relationship between the applicant and his children and step-children. The applicant appears to agree that his contact with the children and grandchildren has been minimal since his detention in 2017. There is little evidence to show that the applicant has played a meaningful role in the children's and grandchildren's lives since at least since incarceration and possibly from the time he moved out of the family home in 2016. Importantly, there is little evidence to satisfy the Tribunal that the family's finances had been adversely affected since the applicant lost the opportunity for employment or that the family had been unable to meet their financial obligations as a result of the limited support the applicant has been able to provide in recent years. There is little evidence on whether the family are able to access income from other sources, such as employment, Centrelink, support from family or friends. On the evidence before it, the Tribunal is not satisfied that the family, and minor children, will experience financial hardship if the applicant's visa remains cancelled.
[70] The applicant submits that his removal from Australia would cause financial hardship to his partner, and also emotional hardship to his partner and her children and grandchildren. The applicant states in his revocation request that he purchased a car for his partner and through his employment, he contributed to the payment of bills, food and rent. Ms Ratu provided a statement to the Tribunal in which she refers to the financial hardship and states that she needs her husband at home to support her. The Tribunal is prepared to accept that the applicant contributed to the family's budget, when he was staying with his partner…The applicant states that despite moving away from his family, he continued to spend time with them on the weekends and he spoke to his wife regularly but there is little evidence of the applicant providing ongoing financial support to his partner and her family since 2016. As noted above, there is insufficient evidence before the Tribunal to establish whether the family have other sources of income to meet their financial obligations without the help of the applicant.
[72] The Tribunal is also mindful that the applicant had spent considerable time in detention, first in criminal detention and later in immigration detention. During the period of his incarceration, the applicant would not have been able to engage in gainful employment and contribute to the family's finances, although he claims that his wife took his savings while he was in detention. There is no evidence before the Tribunal to indicate that as a result, the family had been adversely affected. Thus, while the Tribunal accepts that the applicant did contribute financially to the family, the Tribunal does not accept that if his visa remains cancelled, the family will suffer financial hardship.
95 Some parts of these passages indicate that the AAT did consider whether non-revocation would adversely affect the applicant's family (including the minor children), but it found that there was insufficient evidence to make such a finding. For example, in [52], the AAT said there was "little evidence" to satisfy it that the family's finances had been adversely affected or that they had been unable to meet their financial obligations as a result of the more limited support he has been able to provide in recent years (while the applicant had been in detention). Similarly, at [72] the AAT said there was "no evidence" before it to indicate that the family had been adversely affected financially, as a result of the applicant's reduced ability to contribute to the family's finances during his period in detention. Those conclusions are not necessarily inconsistent with the AAT's acceptance of the applicant's evidence that he provided financial support to the family while he was employed and that his wife had drawn on his savings when she visited him in detention.
96 While minds may differ over whether the AAT statement's about the inadequacy or absence of evidence are correct (which is not the relevant issue in a judicial review challenge), the relevant statements may be interpreted as suggesting that the AAT did consider the applicant's claim of financial hardship as articulated by him. It was open to the AAT to find that, where there is a paucity of evidence, it is unable to make a determination on that aspect of the claim (Paerau at [27] and [117]-[119]). On this reading of the AAT's reasons, the AAT considered the claim, but concluded that the limited evidence did not support a finding that there would be an adverse financial impact on the applicant's family.
97 Other parts of the quoted passages may suggest that the AAT's comments on the evidence of the family being adversely affected financially were regarded by it as findings intermediate to its determination of the applicant's claim that non-revocation of his visa cancellation would result in financial hardship for his family. That is the applicant's reading of the AAT's reasons.
98 In my view, that is not a fair or correct reading of the AAT's reasons and the former reading is to be preferred, particularly having regard to the emphasis the AAT repeatedly gave to the limited nature of the evidence before it.
99 This is not a case such as Goundar or BCR16, where the decision-maker truncated consideration of the claim put forward by the applicant. In contrast, in the present case the AAT has expressed conclusions or views on the matters which the applicant now says were not properly considered by it. Furthermore, unlike Goundar and BCR16, there is nothing in the AAT's reasons to indicate that it misunderstood the applicant's claim.
100 For these reasons, the applicant's principal submissions on ground 2 fail. There remains, however, the alternative contention that the AAT failed to make an obvious enquiry about critical facts that were readily ascertained.
101 The general relevant principle is to be found in SZIAI at [25] (footnote omitted):
Although decisions in the Federal Court concerned with a failure to make obvious inquiries have led to references to a "duty to inquire", that term is apt to direct consideration away from the question whether the decision which is under review is vitiated by jurisdictional error. The duty imposed under the Tribunal by the Migration Act is a duty to review. It may be that a failure to make an obvious inquiry about a critical fact, the existence of which is easily ascertained, could, in some circumstances, supply a sufficient link to the outcome to constitute failure to review. If so, such a failure could give rise to jurisdictional error by constructive failure to exercise jurisdiction. It may be that failure to make such an inquiry results in a decision being affected in some other way that manifest itself as jurisdictional error. It is not necessary to explore these questions of principle in this case…
102 Earlier, in Prasad at 169-170, Wilcox J expressed a tentative view that in some circumstances it may be legally unreasonable to fail to make obvious enquiries into material that is readily available. In Prasad such a failure was regarded as relevant to identifying the field of material that the Court could have regard to in conducting a judicial review of the operative decision. In Minister for Immigration and Citizenship v Le [2007] FCA 1318; 164 FCR 151 at [60]-[67], Kenny J surveyed the relevant authorities following Prasad. Her Honour described the jurisdictional error as one of vitiating unreasonableness arising from the manner in which the decision was made (at [63]).
103 Significantly, the relevant challenge here focusses on the AAT's failure to take certain action and there are no reasons available to explain this aspect of the AAT decision-making process (noting that there is no obligation on the AAT to give reasons for the non-exercise of a procedural power of this kind: Minister for Immigration and Citizenship v SZGUR [2011] HCA 1; 241 CLR 594 at [69]; BVD17 v Minister for Immigration and Border Protection [2019] HCA 34 at [16]).
104 The applicant says that once the AAT reached the view that the evidence before it was insufficient to make particular findings as to the best interests of the minor children, it should have made further attempts to gather the evidence necessary to enable it to make those findings. However, as the Minister submitted, the obvious enquiry which the applicant alleges should have been made was not one that identified specific information or evidence that the AAT could have readily obtained and which would have admitted a clear answer to a critical fact.
105 From the AAT's perspective, the extent of any particular value that that further information may have held was entirely speculative. Nor would it have known how easily such information may be obtained, when it might be obtained and what opportunity to the Minister to consider and test that further evidence, procedural fairness may have required. For that reason, the present case is far removed from one such as Wei which concerned specific information which the primary decision-maker was able to obtain, without difficulty or delay (see Wei at [51]).
106 Having regard to these matters, the alternative submission with respect to ground 2 fails.
