The merits of the proposed single ground of appeal
36 As is apparent from the tortured procedural history of this appeal proceeding, the appellant belatedly stated that he wished only to press the single ground in his latest proposed amended notice of appeal.
37 It is apt to set out the relevant parts of various provisions of the Migration Act upon which the appellant relies, namely ss 189, 196(1), 197C(1) and (2), 198, 198AD and 198AH (as in force at the relevant times):
189 Detention of unlawful non-citizens
(1) If an officer knows or reasonably suspects that a person in the migration zone (other than an excised offshore place) is an unlawful non-citizen, the officer must detain the person.
…
196 Duration of detention
(1) An unlawful non-citizen detained under section 189 must be kept in immigration detention until:
(a) he or she is removed from Australia under section 198 or 199; or
(aa) an officer begins to deal with the non citizen under subsection 198AD(3); or
…
197C Relevance of Australia's non-refoulement obligations to removal of unlawful non-citizens under section 198
(1) For the purposes of section 198, it is irrelevant whether Australia has non-refoulement obligations in respect of an unlawful non-citizen.
(2) An officer's duty to remove as soon as reasonably practicable an unlawful non-citizen under section 198 arises irrespective of whether there has been an assessment, according to law, of Australia's non-refoulement obligations in respect of the non-citizen.
…
198 Removal from Australia of unlawful non-citizens
Removal on request
(1) An officer must remove as soon as reasonably practicable an unlawful non-citizen who asks the Minister, in writing, to be so removed.
Removal of transitory persons brought to Australia for a temporary purpose
(1A) In the case of an unlawful non-citizen who has been brought to Australia under section 198B or repealed section 198C for a temporary purpose, an officer must remove the person as soon as reasonably practicable after the person no longer needs to be in Australia for that purpose (whether or not the purpose has been achieved).
Note 1: Some unlawful non-citizens are transitory persons. Section 198B provides for transitory persons to be brought to Australia for a temporary purpose. See the definition of transitory person in subsection 5(1).
Note 2: Section 198C was repealed by the Migration Amendment (Repairing Medical Transfers) Act 2019. It provided for certain transitory persons to be brought to Australia for a temporary purpose (including the temporary purpose of medical or psychiatric assessment or treatment).
…
(11) This section does not apply to an unauthorised maritime arrival to whom section 198AD applies.
…
198AD Taking unauthorised maritime arrivals to a regional processing country
(1) Subject to sections 198AE, 198AF and 198AG, this section applies to an unauthorised maritime arrival who is detained under section 189.
Note: For when this section applies to a transitory person, see section 198AH.
(2) An officer must, as soon as reasonably practicable, take an unauthorised maritime arrival to whom this section applies from Australia to a regional processing country.
…
Powers of an officer
(3) For the purposes of subsection (2) and without limiting that subsection, an officer may do any or all of the following things within or outside Australia:
(a) place the unauthorised maritime arrival on a vehicle or vessel;
(b) restrain the unauthorised maritime arrival on a vehicle or vessel;
(c) remove the unauthorised maritime arrival from:
(i) the place at which the unauthorised maritime arrival is detained; or
(ii) a vehicle or vessel;
(d) use such force as is necessary and reasonable.
(4) If, in the course of taking an unauthorised maritime arrival to a regional processing country, an officer considers that it is necessary to return the unauthorised maritime arrival to Australia:
(a) subsection (3) applies until the unauthorised maritime arrival is returned to Australia; and
(b) section 42 does not apply in relation to the unauthorised maritime arrival's return to Australia.
Ministerial direction
(5) If there are 2 or more regional processing countries, the Minister must, in writing, direct an officer to take an unauthorised maritime arrival, or a class of unauthorised maritime arrivals, under subsection (2) to the regional processing country specified by the Minister in the direction.
(6) If the Minister gives an officer a direction under subsection (5), the officer must comply with the direction.
(7) The duty under subsection (5) may only be performed by the Minister personally.
(8) The only condition for the performance of the duty under subsection (5) is that the Minister thinks that it is in the public interest to direct the officer to take an unauthorised maritime arrival, or a class of unauthorised maritime arrivals, under subsection (2) to the regional processing country specified by the Minister in the direction.
(9) The rules of natural justice do not apply to the performance of the duty under subsection (5).
(10) A direction under subsection (5) is not a legislative instrument.
Not in immigration detention
(11) An unauthorised maritime arrival who is being dealt with under subsection (3) is taken not to be in immigration detention (as defined in subsection 5(1)).
Meaning of officer
(12) In this section, officer means an officer within the meaning of section 5, and includes a member of the Australian Defence Force.
…
198AH Application of section 198AD to certain transitory persons
(1) Section 198AD applies, subject to sections 198AE, 198AF and 198AG, to a transitory person if, and only if, the person is covered by subsection (1A) or (1B).
(1A) A transitory person is covered by this subsection if:
(a) the person is an unauthorised maritime arrival who is brought to Australia from a regional processing country under section 198B or repealed section 198C for a temporary purpose; and
(b) the person is detained under section 189; and
(c) the person no longer needs to be in Australia for the temporary purpose (whether or not the purpose has been achieved).
Note: Section 198C was repealed by the Migration Amendment (Repairing Medical Transfers) Act 2019. It provided for certain transitory persons to be brought to Australia for a temporary purpose (including the temporary purpose of medical or psychiatric assessment or treatment).
(1B) A transitory person (a transitory child) is covered by this subsection if:
(a) a transitory person covered by subsection (1A) gives birth to the transitory child while in Australia; and
(b) the transitory child is detained under section 189; and
(c) the transitory child is a transitory person because of paragraph (e) of the definition of transitory person in subsection 5(1).
(2) Subsection (1) of this section applies whether or not the transitory person has been assessed to be covered by the definition of refugee in Article 1A of the Refugees Convention as amended by the Refugees Protocol.
38 The appellant's submissions in support of the proposed single ground of appeal may be summarised as follows. First, he contended that s 197C does not apply to a removal under s 198AD. He added that he has raised non-refoulement claims with respect to both Nauru and PNG and claims that he has a right to have a non-refoulement assessment conducted prior to his removal. He said that he suffered serious harm in PNG after he was taken there in 2013 and in circumstances were no non-refoulement assessment had been carried out. He relied on what the Full Court (Griffiths, Mortimer and Perry JJ) said in AOU21 at [54] and [116], as well as Kerr J's observations in MB at [65]-[66].
39 In support of his contentions regarding Australia's non-refoulement obligations, the appellant referred to Art 13 of the International Covenant on Civil and Political Rights and Arts 32 and 33 of the Convention Relating to the Status of Refugees (1951), as amended by the Protocol Relating to the Status of Refugees (1967).
40 The appellant relied upon the Full Court's decision in Ibrahim v Minister for Home Affairs [2019] FCAFC 89; 270 FCR 12 regarding Australia's non-refoulement obligations. He submitted that there would be a "lacuna" in the law if the appellant could be sent to a regional processing country without a non-refoulement assessment and would also give rise to an inconsistency with Australia's international obligations, citing NAGV and NAGW of 2002 v Minister for Immigration and Multicultural and Indigenous Affairs [2005] HCA 6; 222 CLR 161 at [93]-[94] per Kirby J.
41 Turning to the merit of the proposed ground of appeal, it should be emphasised at the outset that, as stated in Vu at [43], merit alone will generally be insufficient to attract a grant of leave to amend. Other considerations include whether an acceptable explanation has been given for the ground not being run below, the nature and extent of any injustice that may arise if leave is not granted and the lack of prejudice to the opposing party.
42 Without descending into a detailed assessment of the proposed ground, on its face it appears weak. The core proposition that there is an obligation to conduct a non-refoulement assessment prior to the appellant being removed to PNG is inconsistent with authorities such as NATB v Minister for Immigration and Multicultural and Indigenous Affairs [2003] FCAFC 292; 133 FCR 506 at [13] and [53] per Wilcox, Lindgren and Bennett JJ:
13. The appeals concern the proper construction of the verb 'remove', and, perhaps more importantly, its qualifier 'as soon as reasonably practicable'. The appeals raise the issue whether death, torture, persecution or other mistreatment of an unlawful citizen which is likely, or even almost certain, to occur after he or she is removed from Australia to another country, is to be taken into account for the purpose of determining whether it is 'reasonably practicable' to 'remove' him or her from Australia. For the reasons given below, in our opinion, those matters are not to be taken into account for that purpose.
…
53. This second limitation is of critical importance to the resolution of the appellants' principal argument. In our opinion, the reference to reasonable practicability in the subsection does not require an officer to take into account what is likely, or even virtually certain, to befall the unlawful non-citizen after removal is complete; and removal is complete, at the latest, once the person has been admitted by, and into, the receiving country. Even if it is virtually certain that he or she will be killed, tortured or persecuted in that country, whether on a Refugees Convention ground or not, that is not a practical consideration going to the ability to remove from Australia. Rather, it is a consideration about a likely course of events following removal from Australia.
43 Further, as the respondents point out, the proposed ground is inconsistent with Gageler J's statements in Plaintiff M96A/2016 v Commonwealth of Australia [2017] HCA 16; 261 CLR 582 at [37] and [40], as affirmed by the Full Court in AOU21 at [143]-[144]. Moreover, AOU21 is distinguishable, as is reflected in the primary judge's acceptance (correctly) of the respondents' submissions on that matter below, and which are set out at [15] and [16] above.
44 The appellant placed heavy reliance on Kerr J's observations in MB at [65]-[66] (emphasis added):
65. I will expand on my reasons for having reached that conclusion later but before I turn to that I should interpolate that I accept the submission advanced by the Applicant that he is entitled to have his claims for protection in respect of Nauru determined and, if found to be well founded, not to be refouled to Nauru. I accept that as defined by s 5(1) of the Migration Act, Australia's non-refoulement obligations include those arising because Australia is a party to the Refugee Convention and/or the ICCPR as well as any obligations accorded by customary international law as are of a similar kind: Ibrahim v Minister for Home Affairs [2019] FCAFC 89.
66. Those obligations extend to Nauru as they do to any other nation. I record that I am entirely unpersuaded of the submission the Respondents advanced that the scheme of the Migration Act requires a conclusion that any claims the Applicant might seek to advance that he is owed non-refoulement obligations with respect to Nauru could not stand in the way of his being taken to Nauru pursuant to s 198AD of the Migration Act. Having had the benefit of full argument on the subject, I am satisfied that the Applicant's submission must be accepted that the omission in s 197C of the Migration Act of a reference to s 198AD is not open to be dismissed as a mere drafting oversight. That is so notwithstanding the Migration Act does not provide a statutory mechanism to determine such a claim. That the need to do so was not anticipated is hardly surprising. I take it to be a matter of common knowledge within the meaning of s 144 of the Evidence Act 1995 (Cth) that the large influx of unauthorised maritime arrivals which prompted the passage of Part 2 Division 8 Subdivision B of the Migration Act did not include those fleeing from either of the two countries later designated as regional processing countries. That a statutory mechanism has not been provided for does not mean the right to have such a claim determined does not exist. The proposition that an assessment of the Applicant's claims would be capable of being administratively facilitated if required was the foundation premise of the Respondents' submission referred to at [58] above.
45 These observations in MB are in the nature of obiter dicta. It is difficult to reconcile them with the Full Court's decision in NATB. Nor is it apparent whether his Honour was taken to ss 198AA(b) or 198AH(2). Justice Kerr ultimately accepted in MB that there was a lawful basis for detention in that case. Moreover, Kerr J's decision is not inconsistent with the core proposition advanced by the respondents, namely that s 198AD applies where s 198AH(1) provides that it does.
46 I am not persuaded that the merit of the proposed ground of appeal is sufficient, of itself, to warrant the appellant being granted leave to amend to run a new ground for the first time on appeal. Moreover, there are several other reasons why leave should not be granted, as set out above.
