(a) Did the Commonwealth take reasonable practicable steps during the relevant period of immigration detention?
103 For the following reasons, I am satisfied on the basis of the evidence adduced by the Commonwealth that it did take reasonable practicable steps during the relevant maximum period of the allegedly unlawful immigration detention here, as well as within the two smaller sub-periods as identified at [94] above.
104 First, based on the evidence of Mr Prescilla and Mr Kumar, I find that during the entirety of maximum alleged unlawful immigration detention period, it was reasonably suspected by a Commonwealth officer that the applicant was an unlawful non-citizen, which engaged the obligation to detain him throughout that period in accordance with s 189 of the Act.
105 Secondly, I find that the purpose for which the applicant was detained during the entirety of the maximum alleged unlawful immigration detention period was for the permissible purpose of him being removed from Australia, as required by s 198(6) of the Act.
106 Thirdly, for the following reasons I find that the Commonwealth has demonstrated that sufficient reasonable practicable steps were taken throughout the entirety of the alleged maximum unlawful immigration detention period to discharge the statutory obligation imposed by s 198(6):
(a) The objective assessment of the reasonableness of the Commonwealth's steps or any inactivity during the relevant period must take account of the following important relevant features of the applicant's individual circumstances:
(i) The applicant's statelessness and lack of any travel documents created significant practical difficulties for the Commonwealth in finding a country which would accept him, as described by Ms Davis and Mr Knight and, to a lesser extent, Mr Gillard. That is particularly so with Iran and Iraq, as is highlighted in the evidence of Ms Davis and Mr Knight, which is supported by documentary evidence as identified at [48]-[50] above.
(ii) Those difficulties were exacerbated by the applicant's consistent refusal throughout the relevant period to give his consent to being removed from Australia to any country, let alone Iran or Iraq.
(iii) As to the applicant's capacity to give informed consent to his removal from Australia, a matter which was raised in the present proceeding, I accept the Commonwealth's submission that there is no evidence to indicate that, even if a guardian had been appointed during the alleged period of unlawful immigration detention, this may have produced a different outcome. In particular, it is most improbable that a guardian would have given consent to the applicant's removal to either Iran or Iraq given his status as a Faili Kurd and the relevant findings of the IAA.
(iv) It is difficult to be critical of the Commonwealth for not making direct inquiries of countries apart from Iran and Iraq as to whether they would accept the applicant given the applicant's stated position that he would not consent to his removal to any country, and his lack of travel documents. The evidence before the Court did not indicate that any country would be willing to accept a person with these characteristics, not to mention his previous criminal record and conduct which underpinned the Minister's latest decision to refuse him a Protection Visa.
(v) I accept Mr Knight's evidence of meetings he had on 30 October 2019 and 14 February 2020 with the Iranian Consul regarding involuntary removals to Iran. These discussions related to the possibility of returning six Iranian nationals who were in the off-shore detainee network and who were involuntary returns, but not the applicant himself, as Mr Knight candidly acknowledged. I accept this evidence. I also accept that, at least in Mr Knight's own mind, those discussions were intended by him to hopefully obtain Iranian approval in relation to a smaller group of involuntary removals as a step towards Mr Knight then working to change the Iranian policy on involuntary removals more broadly. There is no reason to think that Mr Knight's intentions were limited to the return of Iranian citizens.
(vi) It is true that there were some intervals during the relevant period when there was no direct activity to remove the applicant from Australia, but that fact alone is not determinative. The relevant question is whether such periods of inactivity were unreasonable in the applicant's particular circumstances. For the following reasons, I consider that they were not unreasonable. For example, there was a period of approximately two weeks prior to Mr Kumar referring the applicant to the Removals Team on 22 October 2019 when no active steps were evidently taken to remove the applicant, notwithstanding the expiration of the period within which the applicant could have commenced judicial review proceedings in relation to the Minister's decision dated 4 September 2019. It is evident from the notes of the first case review conducted by Mr Kumar on 16 September 2019 (i.e. shortly after Mr Kumar had taken over as the applicant's DSRO) that it was considered that the time period for commencing judicial review proceedings had not yet expired. Moreover, it was noted that the applicant was unwilling voluntarily to return to Iran. Mr Kumar conducted his second case review of the applicant on 28 October 2019 (i.e. six days after he had referred the applicant to the Removals Team). The notes of that case review record that, as at 3 October 2019, "s 195a + s 197ab referrals remain ongoing (adv from CCRS/SRSS)". Similarly, although there was a regrettable failure to conduct two-monthly reviews of the applicant's case in January, March and May 2020 as part of procedure described by Ms Dee for the "protracted caseload", I consider that Ms Dee adequately explained that failure (see [43] above). It is evident that other steps were taken during this period, notwithstanding the failure to conduct two-monthly reviews, including generic steps described above concerning the position regarding involuntary removals to Iran which, even if not directed to the applicant personally, had potential implications for him depending on their outcome.
(b) As described by Ms Masri, Ms Ly and Ms Dee, shortly after 22 October 2019 when the applicant was referred by Mr Kumar to the Removals Team, his case was assessed as one which should be included in the "protracted caseload", which comprised removal cases with particular complexity and to whom there was a dedicated team of people. This was an appropriate management step, which was intended to have complicated and challenging cases, such as the applicant's, dealt with by a separate team. Because of the complexities and complications relating to cases in the protracted caseload cohort, it is reasonable to expect that progress of such cases will often be more challenging and time-consuming compared with more straightforward cases.
(c) As indicated above, I accept Ms Dee's unchallenged reasons why she believed that there was a failure to conduct two-monthly reviews of the applicant in January, March and May 2020. Those omissions should not have occurred and if they had been accompanied by other relevant incidents, I may have taken a different view of this regrettable failure. As emphasised above, however, a broad view needs to be taken in assessing the reasonableness of the Commonwealth's conduct.
(d) Since at least mid-March 2020, there were very real practical difficulties presented by the COVID-19 pandemic in arranging for the applicant to be removed from Australia to any other country. These difficulties were described by Ms Davis, Ms Dee and Mr Wright, whose evidence I accept. In particular, I accept Ms Dee's evidence that, even if it had been possible to remove the applicant to some other country during the relevant period, this could only have been done if he had a security escort because of his criminal record and the requirements of the Aviation Transport Security Regulations 2005 (Cth). These claims were not contested by the applicant in the present proceeding. I accept Ms Davis's evidence that from mid-March 2020 all escorted removals were cancelled and that since that time no Serco escort has been used on a commercial flight. Ms Davis deposed that, as at mid-December 2020, escorted removals using Serco security guards had recommenced, but only on chartered flights. Ms Davis added that she had arranged a number of charter flights to remove unlawful non-citizens from Australia to countries such as New Zealand, the United Kingdom, Vietnam and Italy. This does not assist the applicant's case in circumstances where the recommencement of removals on some chartered flights is outside the relevant alleged unlawful immigration period. In addition, the applicant steadfastly refused his consent to be taken to any country during that period and lacked any travel documents.
(e) As to the applicant's complaint that the process of assessing his identity could have commenced earlier than 4 September 2020, even if this complaint be accepted, it is difficult to see that it would have had any material bearing on the applicant's case given his lack of travel documents and his steadfast refusal to be removed to either Iran or Iraq or, indeed, to any other country.
107 For all these reasons, and having regard to the evidence adduced by the Commonwealth, most of which was not challenged by the applicant, I accept the Commonwealth's claim that it took reasonable practicable steps throughout the entirety of the relevant period to have the applicant removed from Australia.
108 That conclusion should not obscure the dilemmas created by s 198(6) and the related statutory provisions regarding mandatory immigration detention and removal from Australia. The applicant's case vividly illustrates the quandary created for Commonwealth officers who, on the one hand, are statutorily obliged to remove a person such as the applicant as soon as is reasonably practicable, yet the practical reality is that such removal is effectively impossible in the foreseeable future because of matters which are beyond the Commonwealth's control (as is the case in the present proceeding during the relevant alleged period of unlawful immigration detention). As Hayne J observed in Al-Kateb at [231], even in a case where there is no real likelihood or prospect of an unlawful non-citizen being removed in the reasonably foreseeable future, this does not mean that continued detention is not for the purpose of subsequent removal. The majority view in that case was that the obligation under s 198(6) should not be read as being subject to a narrower limitation than its words permit. Rather, the time for removal is fixed by reference to reasonable practicability and not some narrower limitation such as, for example, "within a reasonable time".
