Failure to take into account a legal consequence of the decision
22 The applicant's originating application relies on a ground that:
5. The respondent failed to take into account that the applicant after 1 July 2014 would not be a Vietnamese citizen with consequences that the applicant would therefore be detained indefinitely in Australia or for a long period of time.
23 This ground, as argued, was that the respondent failed to take into account a relevant consideration, namely a legal consequence of the decision to cancel: that consequence being that the applicant is liable to indefinite detention in Australia.
24 Counsel for the applicant argued that the ITOA indicated that under Vietnamese law persons in the applicant's position who failed to register for retention of Vietnamese nationality by 1 July 2014 would lose their Vietnamese nationality. Counsel relied on the judgment of the Full Court in NBNB v Minister for Immigration and Border Protection (2014) 220 FCR 44 for the proposition that the applicant faces indefinite detention, and that this is a consideration that must be taken into account. Counsel pointed out that the Minister's reasons did not mention the issue of whether or not the applicant had lost his Vietnamese nationality.
25 Counsel for the Minister submitted that the applicant has not necessarily lost his Vietnamese nationality, and that the judgment in NBNB does not require the Minister to take into account the possible loss of the applicant's Vietnamese citizenship. Counsel argued that, in any event, the Minister had taken this matter into account. Counsel submitted that even if the applicant has lost his Vietnamese nationality, it is not a necessary consequence that he will be permanently detained in Australia, as he may be granted a visa. Counsel also submitted that the Court should refuse relief in the exercise of its discretion because it was open for the applicant to register for the retention of his Vietnamese nationality, but he failed to do so.
26 There are four issues for the Court to consider:
(a) What are the relevant legal, or statutory, consequences of the decision to cancel the visa?
(b) Was the Minister bound to take into account those consequences?
(c) Did the Minister take into account those consequences?
(d) Should relief be refused in the exercise of the Court's discretion?
27 As to the first issue, the ITOA noted that under Vietnamese law, "overseas Vietnamese" without a Vietnamese passport would lose their Vietnamese nationality unless they registered for retention of their nationality by 1 July 2014. The ITOA was dated 16 May 2014 and was before the Minister. The 1 July 2014 deadline had passed by the time the Minister made his decision. There was no material before the Minister suggesting that the deadline had been extended by the Vietnamese government, or that the applicant had obtained a Vietnamese passport, or had registered for retention of his Vietnamese nationality. On the evidence before the Minister, the possibility that any of these events had occurred could only be the subject of speculation. Therefore, the material available to the Minister was consistent only with the applicant having already lost his Vietnamese nationality.
28 There are two judgments of the Full Court highly relevant to the outcome of this case. The first is NBNB, which has already been mentioned. The second is NBMZ v Minister for Immigration and Border Protection (2014) 220 FCR 1. Both cases concerned the consequences of a decision of the Minister refusing the grant of a protection visa pursuant to s 501(1) of the Migration Act. In each case, there was a combination of four factors at work. First, the applicants were non-citizens who did not hold visas. Second, Australia's non-refoulement obligations meant that the applicants could not be returned to their country of origin. Third, ss 189, 196 and 198 of the Migration Act require the detention of a non-citizen until he or she is removed from Australia. Fourth, the consequence of the High Court's judgment in Al-Kateb v Godwin (2004) 219 CLR 562 was that the applicants faced the prospect of indefinite detention in Australia.
29 On the evidence before the Minister in the present case, the applicant had lost his Vietnamese nationality. A consequence of the cancellation of his visa is that he must be detained until removed from Australia; but he is stateless and cannot be removed from Australia in the foreseeable future.
30 However, counsel for the Minister submits that it is not a necessary consequence of these circumstances that the applicant will be indefinitely detained. Under s 195 of the Migration Act, a detainee may apply for a visa, and under s 195A, the Minister may grant a visa if the Minister thinks it is the public interest to do so. In NBMZ, the Full Court rejected such an argument, saying that the possibility of any visa under s 195A was merely a matter of speculation and the applicant was entitled to have his application determined on the hypothesis that he will be indefinitely detained: Allsop CJ and Katzmann J at [4], Buchanan J at [123]-[129] . The same position applies in this case.
31 It follows that a legal, or statutory, consequence of the Minister's decision to cancel the applicant's visa is that he faces indefinite detention in Australia.
32 The second issue to be considered is whether the Minister was required to take into account that the applicant faces indefinite detention. In NBMZ, Allsop CJ and Katzmann J held:
[9] The Minister must take into account the Act and its operation in making a decision; to make a decision without taking into account what Parliament has prescribed by way of legal consequence is to fail to take into account the legal framework of the decision. At a functional level this is reinforced if the legal consequences of the decision are important in human terms: indefinite detention pending removal.
[10] The Minister was required to take into account the legal consequences of his decision. These consequences (indefinite detention) flowed from Australia's obligation of non-refoulement and the terms of the Act.
33 Similarly, in NBNB, Allsop CJ and Katzmann J said:
[2] …As in NBMZ, in the five decisions here, the Minister failed to take into account the mandatory consideration of the legal consequences of the decision being made in the context of Australia's obligation of non-refoulement: indefinite detention.
34 Accordingly, the Minister was required to take into account that the applicant would face indefinite detention if his visa were cancelled.
35 The third issue to be considered is whether the Minister did take into account that the applicant faced indefinite detention.
36 The Minister's reasons did not mention the prospect of indefinite detention. The reasons referred to the ITOA only in the context of whether Australia would breach its treaty obligations against non-refoulement by returning the applicant to Vietnam. The reasons did not refer to the information in the ITOA concerning the loss of the applicant's Vietnamese nationality.
37 In NBMZ, the position was similar. Allsop and Katzmann JJ said:
[16] What was entirely absent from the briefing note, however, and also from the Minister's reasons was any attempt to confront the binary relational legal consequence of Australia's obligation under Art 33 and Australia's policy of mandatory detention: indefinite detention. It may be accepted, at one level of abstraction, that the Minister was aware of ss 189, 196 and 198 of the Act and of the High Court's decision in Al-Kateb. That, however, is not the point. A material omission from a briefing paper may affect the decision-making process based on it: Peko-Wallsend Ltd at 30-31, 45 and 65-66. Also, the written reasons of the Minister may, and generally will (subject to a contrary finding of fact), be taken to be a statement of those matters adverted to, considered and taken into account; and if something is not mentioned, it may be inferred that it has not been adverted to, considered or taken into account: Acts Interpretation Act 1901 (Cth), s 25D, s 501G of the Act and Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323 at [5], [37], [69], [89] and [133].
(Underlining added.)
38 Counsel for the Minister submits that the Minister must be considered to have taken into account the whole of the ITOA, including the discussion of the loss of nationality. Counsel notes that the Minister said in para [41] of his reasons "Having given full consideration to all of these matters, I decided to exercise my discretion to cancel…". Counsel submits that this is an indication that the Minister must have taken into account the discussion in the ITOA concerning loss of Vietnamese nationality.
39 I do not accept that para [41] can be interpreted in this way. The reference to "all of these matters" is to the matters which the Minister had discussed earlier in his reasons. It is not a reference to all of the material that was before him. The Minister's reasons contain no reference to the possible loss of Vietnamese nationality or indefinite detention.
40 Counsel for the Minister also relies on the "catch-all" on the last page of the submission made to the Minister that the Minister had "considered all relevant matters…and all evidence before [him] provided by, or on behalf of, or in relation to Van Linh LE…". Paragraph 34 of the Minster's Statement of Reasons is also in similar terms. The references to "all relevant matters" must be to the matters which the Minister considered were relevant. The matters that the Minister considered were relevant were those set out in the Minister's reasons. Those matters do not include the possible loss of Vietnamese nationality or indefinite detention.
41 The "catch-all" does indicate that the Minister considered "all evidence before [him]". That evidence includes the ITO assessment, and the ITO assessment discusses the possible loss of Vietnamese nationality. I will assume, without deciding, that the "catch-all" is sufficient to indicate that the Minister took that issue into account. However, the ITOA makes no reference to the prospect that the applicant would be liable to indefinite detention in Australia. I therefore infer that the Minister did not take into account that the applicant faced indefinite detention.
42 I consider that the Minister failed to take into account a relevant consideration, namely that a legal consequence of the decision to cancel the visa was that the applicant faced the prospect of indefinite detention in Australia. This was a jurisdictional error.
43 Counsel for the Minister submits that the applicant should be refused relief in the exercise of the Court's discretion because he had not taken the opportunity of registering for the retention of his Vietnamese nationality. It is submitted that this would have avoided the prospect that he would be indefinitely detained in Australia.
44 It is true that the Court may refuse certiorari and mandamus on discretionary grounds. However, to succeed on this basis it would be at least necessary for there to be evidence that the applicant had the opportunity to register for retention of his Vietnamese nationality. This would require evidence that it was open to him to register, and that he could have registered after he became aware of the ITOA and before the deadline. There was no evidence before the Court about the procedure for registering, the time frame in which it could have been done and the practicality of obtaining registration in circumstances in which the applicant had left Vietnam some 29 years earlier. Therefore, the discretion should not be exercised to refuse the applicant relief.
