The facts
3 The applicant was born in 1970 on Daru Island, Papua. At the time, Papua was administered by Australia as a Possession of the Crown and as part of an administrative union known as the Territory of Papua and New Guinea. Papua was, until 1975, part of "Australia" for the purposes of the Australian Citizenship Act 1948 (Cth) (the Citizenship Act). The applicant's grandparents were also born in Papua. He was five years old when, in September 1975, Papua New Guinea (PNG) became an independent sovereign State.
4 By virtue of the Citizenship Act, because he was born in Papua, the applicant was a citizen of Australia at the time of his birth. However, that right of citizenship did not entitle him to enter or reside in Australia. Before Independence Day in September 1975, in order to enter or reside in Australia, the applicant, like all people in a similar position, was required to obtain an entry permit.
5 When PNG became an independent sovereign state in 1975, the applicant automatically acquired PNG citizenship by virtue of the fact that he had two grandparents who were born in Papua: see s 65(1) of the Constitution of the Independent State of Papua New Guinea (the PNG Constitution) (which provided that "[a] person born in the country before Independence Day who has two grand-parents who were born in the country or an adjacent area is a citizen"). For a detailed history of the changes to citizenship effected by the PNG Constitution in 1975, see Re Minister for Immigration and Multicultural and Indigenous Affairs; ex parte AME (2005) 222 CLR 439 at 445-455, [1]-[23].
6 I note for completeness that Part IV of the PNG Constitution relevantly provides in s 64(1) that "no person who has a real foreign citizenship may be or become a citizen [of PNG]". In circumstances where the applicant was born in "Australia", this may appear at first glance to preclude the applicant from being deemed a PNG citizen under the PNG Constitution. However, the applicant was not a "real foreign citizen" because, although he was an Australian citizen by virtue of his birth in Papua, he had never been granted a right to permanent residence in Australia: see s 64(4) of the PNG Constitution.
7 The applicant moved to Darnley Island in 1976. Darnley Island was, and is, part of Australia. In 1982, the applicant was granted an Australian Permanent Entry Permit, which later became a "Class BF transitional (permanent) Visa" (the visa).
8 In May 1996, the applicant commenced service with the defence forces of the Commonwealth of Australia as a private in the Army Reserves. He applied for Australian citizenship in March 1997, which was granted in February the next year, when, it seems, he was still serving in the Army Reserves. In May 2001, however, before Australian citizenship was conferred, the grant of citizenship was revoked on character grounds.
9 As an adult, the applicant committed a number of serious criminal offences. In 2007, for example, he was convicted of an offence involving a sexual attack on an elderly woman in her home and sentenced to 4 years in jail. He has been detained, and remains, in immigration detention since he was released from jail.
10 On 10 June 2015, a delegate of the respondent made a decision mandatorily to cancel the applicant's visa under s 501(3A) of the Migration Act 1958 (Cth). Section 501(3A) provides:
The Minister must cancel a visa that has been granted to a person if:
(a) the Minister is satisfied that the person does not pass the character test because of the operation of:
(i) paragraph (6)(a) (substantial criminal record), on the basis of paragraph (7)(a), (b) or (c); or
(ii) paragraph (6)(e) (sexually based offences involving a child); and
(b) the person is serving a sentence of imprisonment, on a full-time basis in a custodial institution, for an offence against a law of the Commonwealth, a State or a Territory.
11 The fact and significance of s 70(1)(e) of the PNG Constitution was not known by the applicant or the delegate (or the Minister).
12 The delegate was satisfied that the applicant did not pass the character test because of the operation of s 501(7)(c) (substantial criminal record) (s 501(3A)(a)(i)) and because he was serving a sentence of imprisonment on a full-time basis (s 501(3A)(b)). It follows that the mandatory terms of s 501(3A) required the Minister to cancel the applicant's visa (the cancellation decision).
13 The applicant was told that he could request revocation of the decision to cancel his visa. The applicant then sought such revocation.
14 On 31 March 2016, the Minister's Department, the Department for Immigration and Border Protection (the Department), sent further information to the applicant that might have been taken into account when making its decision as to whether to revoke the cancellation decision and invited comment.
15 On 19 April 2016, the applicant responded to the invitation to comment.
16 On 23 September 2016, the applicant returned to the Department a completed Personal Circumstances Form.
17 On 5 October 2016, the Minister made a decision under s 501CA(4) of the Act not to revoke the cancellation decision.
18 Section 501CA of the Act relevantly provides:
Cancellation of visa--revocation of decision under subsection 501(3A) (person serving sentence of imprisonment)
(1) This section applies if the Minister makes a decision (the original decision) under subsection 501(3A) (person serving sentence of imprisonment) to cancel a visa that has been granted to a person.
(2) For the purposes of this section, relevant information is information (other than non-disclosable information) that the Minister considers:
(a) would be the reason, or a part of the reason, for making the original decision; and
(b) is specifically about the person or another person and is not just about a class of persons of which the person or other person is a member.
(3) As soon as practicable after making the original decision, the Minister must:
(a) give the person, in the way that the Minister considers appropriate in the circumstances:
(i) a written notice that sets out the original decision; and
(ii) particulars of the relevant information; and
(b) invite the person to make representations to the Minister, within the period and in the manner ascertained in accordance with the regulations, about revocation of the original decision.
(4) The Minister may revoke the original decision if:
(a) the person makes representations in accordance with the invitation; and
(b) the Minister is satisfied:
(i) that the person passes the character test (as defined by section 501); or
(ii) that there is another reason why the original decision should be revoked.
(5) If the Minister revokes the original decision, the original decision is taken not to have been made.
…
19 The Minister's decision was recorded in a statement of reasons signed on 5 October 2016.
20 It is not necessary to record the Minister's reasons for declining to revoke the cancellation decision. It is sufficient for the purposes of this application to note that the decision to do so was premised on the fact that the applicant claimed on multiple occasions, and the Minister accepted (particularly in light of its own assessment that the applicant did not hold Australian citizenship), that the applicant was and remained a citizen of PNG.
21 Sometime after the decision not to revoke the cancellation decision was made, someone (it seems that it was probably a lawyer then assisting pro bono on the applicant's behalf) unearthed the fact that s 70(1)(e) of the PNG Constitution, at all relevant times, provided that " … a citizen who has reached voting age and is of full capacity who - (e) enters or serves in the armed forces of another country, except with the express approval of the Head of State, acting with, and in accordance with, the advice of the National Executive Council … loses his citizenship".
22 It follows, assuming that the applicant had not served in the Australian Army "with the express approval of the Head of State [of PNG]" (of which there was, obviously, no evidence before the Minister), that the applicant in all likelihood lost his citizenship when he "entered" or "served" in the Australian Army. If that is so, then the applicant, not being a citizen of any other country, would be stateless and would, therefore, face the prospect of indefinite immigration detention in Australia.
23 The applicant now seeks to contend that the Minister committed jurisdictional error because he did not consider, or take into account, something that he did not know (that the applicant was, or may be, stateless), and which was contrary to the applicant's own case (that he was a citizen of PNG) and that the Minister did not therefore take into account the prospect of him being indefinitely detained in immigration detention. He also seeks leave, pursuant to s 23 of the Federal Court of Australia Act 1976 (Cth), to adduce further evidence of the relevant provision of the PNG Constitution.
