Duty to inquire
41 The existence and content of any "duty to inquire" that might be imposed on decision-makers was considered at some length by the High Court of Australia in SZIAI. The majority (French CJ, Gummow, Hayne, Crennan, Kiefel and Bell JJ) concluded at [25]:
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 upon 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 a 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 manifests itself as jurisdictional error …
42 It was ultimately not necessary for the High Court in SZIAI to determine the precise nature and extent of the "duty to inquire", given that first, there was nothing before the Court that indicated that further inquiries could have yielded a useful result and second, the response made by SZIAI's solicitors (which did not rise above a bare denial) demonstrated the futility of further inquiry: SZIAI at [26].
43 The applicant placed considerable reliance on the reasoning of the High Court in Uelese in support of his contention that the Tribunal in this case relevantly had a duty to inquire with respect to the best interests of the five minor children.
44 For present purposes, the critical reasoning of French CJ, Kiefel, Bell and Keane JJ in Uelese is as follows:
66 It is apparent that the paucity of evidence referred to in the last sentence of the passage from the reasons of the Tribunal cited above was not due to the unavailability of material evidence. The Tribunal not only declined to act upon the information which was put before it by Ms Fatai, but it also failed to make even the most cursory inquiry to follow up on this information. This is not a case like Paerau v Minister for Immigration and Border Protection, on which the Minister sought to rely; here, the paucity of evidence was a consequence of the view taken by the Tribunal of the preclusory effect of s 500(6H).
67 It is not necessary here to seek to chart the boundaries of the Tribunal's obligation to inquire after the best interests of the children of an applicant for review. There may be cases, hopefully rare, where the evidence presented by the parties does not alert the Tribunal that minor children in Australia may be affected by the decision. There may also be cases where the evidence is such that the only determination which can be made in obedience to cl 9.3(1) of Direction 55 [as Direction 79 then was] is that cancellation is neutral so far as the best interests of any minor child are concerned. In this regard, it is to be noted that cl 9.3(1) requires a "determination about whether cancellation is, or is not, in the best interests of the child" (emphasis added). Sometimes the best decision "about" whether cancellation is, or is not, in the best interests of the child may be that it is neither.
45 On balance, I do not consider that the reasoning in Uelese provides any material support for the applicant's contention that the Tribunal had a positive duty to inquire as to the best interests of the minor children.
46 First, the Tribunal in Uelese had incorrectly proceeded on the basis that it was precluded by reason of s 500(6H) of the Act from making any further inquiry as to the interests of the minor children in Australia. The paucity of the evidence was expressly attributed to the erroneous views that the Tribunal had taken of the preclusory effect of s 500(6H). That was not a misapprehension on the part of the Tribunal in this case.
47 Second, a consequence of the error by the Tribunal in Uelese was that it failed to act upon the information before it of the interests of the minor children. There was no such error by the Tribunal in this case. The Tribunal here expressly referred to the limited evidence before it relevant to the interests of the minor children.
48 Third, a further consequence of the error made by the Tribunal in Uelese was that it had also failed to follow up on information before it by making even the "most cursory inquiry": Uelese at [66]. This error was attributed to the misconception concerning the preclusory nature of s 500(6H), not a freestanding failure to pursue a specific duty to inquire as to the best interests of the minor children.
49 Fourth, the majority in Uelese observed that there may well be cases where the only determination that could be made for the purposes of paragraph 9.3(1) of Direction 55 (the predecessor to Direction 79) was that cancellation was "neutral so far as the best interests of any minor child are concerned". The majority explained that the paragraph required a "determination about whether cancellation is, or is not, in the best interests of the child" (original emphasis) and that sometimes the best decision about "whether cancellation is, or is not, in the best interests of the child may be that it is neither": Uelese at [67].
50 Fifth, the relevant issue in Uelese was not a question of whether the Tribunal went "far enough" but rather a "failure to address a primary consideration", as explained by the majority at [68]:
It is not necessary to canvass these possibilities further because the issue in this case is not whether the Tribunal failed to go far enough to discharge its obligation to conduct its review having regard to the interests of all the appellant's children; rather, the point is that the Tribunal, by reason of its misunderstanding of the effect of s 500(6H), failed to address one of the primary considerations affecting the decision required of it. It failed to conduct the review required by the Act, and thereby fell into jurisdictional error.
(Footnotes omitted.)
51 In my opinion, more relevant for present purposes is the reasoning of the majority in Paerau (Buchanan and Perry JJ in separate judgments). The Tribunal in Pareau had relevantly concluded, given the paucity of evidence before it, that it could not be satisfied as to whether it would be in the best interests of Mr Paerau's minor children for him to remain in Australia or for him to be removed to New Zealand. The Tribunal concluded that in those circumstances, the best interests of minor children consideration did "not weigh against cancellation and, at best, is neutral".
52 Buchanan J focused on the Tribunal's obligation to assess the available material conscientiously, but in circumstances where this material did not permit a "proper conclusion" (original emphasis). His Honour considered that there could be no objection to the Tribunal saying that it was unable to reach a conclusion on the best interests of a child either for or against the cancellation of a visa: Paerau at [27].
53 Perry J considered that the Tribunal's finding on the best interests of minor children consideration equates in the language of the Ministerial direction to a finding that the consideration was not "relevant". Her Honour stated that, in effect, the Tribunal had decided that it had insufficient probative material available to it to be able to embark upon the requisite determination. So read, her Honour reasoned, this was "not a case where the Tribunal made findings on the evidence before it on matters relevant to determining where the best interests of children lie, but failed to complete that process by determining what was in their best interests and taking that into account in balancing that primary consideration against the other considerations": Pareau at [117]-[118], cf Spruill v Minister for Immigration and Citizenship [2012] FCA 1401 (Robertson J).
54 Equally relevant for present purposes, Perry J concluded at [119] of Paerau:
Finally, even if I am wrong in my reading of the Tribunal's reasons and the Tribunal did have regard to the consideration of where the best interests of the children lay - a construction which I accept is available - I do not consider that the error is one which would warrant remitting the matter back to the Tribunal in the exercise of the Court's discretion to grant relief. Once the Tribunal found that, by reason of the paucity of evidence, it could not be satisfied about where the best interests of Mr Paerau's minor children lay, and that was a finding lawfully open to it, there was nothing further for the Tribunal to do with respect to that consideration. The fact that the Tribunal then found that "[a]s such, this consideration does not weigh against cancellation and, at best, is neutral" had in its terms no impact on the result of the balancing exercise which the Tribunal then undertook in accordance with cl 7(1) of the Direction, and therefore had no impact upon its final decision. The further finding was simply superfluous to the Tribunal's decision.
(Emphasis added.)
55 Neither Buchanan nor Perry JJ sought to impose any "duty to inquire" obligation on the Tribunal in circumstances where the evidence before it was insufficient to enable it to form a conclusion as to whether it was in the best interests of minor children for an applicant to remain in Australia or be removed to another country.
56 In my view the position in the present case is largely analogous to the position considered by the Full Court in Paerau.
57 As submitted by counsel for the Minister, the Tribunal here properly recognised that the best interests of the minor children was a mandatory consideration that it had to take into account. The Tribunal considered the evidence before it relevant to that consideration and then concluded that the evidence before it was insufficient to enable it to determine whether or not the consideration weighed favourably or unfavourably to the revocation decision. It was in those circumstances that the Tribunal concluded that the second primary consideration did not weigh in favour of the revocation of the cancellation of the applicant's visa.
58 It might well be accepted that there was an obligation on the Tribunal to make an "obvious inquiry" such as "what was the relationship of the minor children to the applicant?" and "what is the evidence that the applicant relies upon with respect to the best interests of minor children?" I do not accept, however, that there was any obligation on the Tribunal to seek to supplement or independently investigate the evidence relied upon by the applicant for the best interests of the minor children consideration, particularly in circumstances where the Tribunal had expressly raised its concerns as to the scope of the material advanced by the applicant to his representative in the course of the hearing before it. The role of the Tribunal was to consider the representations made to it to determine whether the criteria in s 501CA(4) had been met: Taualii at [96] (Anderson J); Pennie at [14] (Davies, Derrington and Colvin JJ).
59 For these reasons, I do not consider that jurisdictional error has been established by the applicant in relation to this ground.
