6 The first and third respondents have filed a notice of objection to competency and a notice of motion seeking that the proceeding be dismissed as an abuse of the process of the Court. The objection to the competency of the present application to invoke the jurisdiction of this Court is based on the limitation of the Court's original jurisdiction imposed by s 476A(1) of the Migration Act. This limitation is discussed further below.
7 In the first paragraph of his details of claim the applicant seeks to challenge the decisions made by the delegate of the first respondent and by the second respondent, the Migration Review Tribunal. The first point to be made is that the decision of the delegate is a spent force. In reviewing the delegate's decision the Tribunal may exercise all the powers and discretions that the Act confers on the delegate; s 349. Its decision is substituted for that of the delegate and therefore it is the challenge to the Tribunal's decision which is the substance of the first claim and of this proceeding. The claims made in paragraphs 2 and 3 of the details of claim are ancillary to and consequential upon the Tribunal's decision referred to in paragraph 1. They challenge the legality of the applicant's detention and the cancellation of his visa.
8 A non-citizen who is in the migration zone and does not hold a visa is an unlawful non-citizen; Migration Act ss 13 and 14. Subject to exceptions not presently relevant, s 189 of the Act requires an officer to detain a person in the migration zone if he or she knows or suspects the person to be an unlawful non-citizen. In other words, claims 2 and 3 do not raise any issue not raised in claim 1.
9 A similar point may be made about the following orders which are sought by the applicant:
(a) An order in the nature of habeas corpus directed to the first and third respondents ordering the release the [sic] applicant from immigration detention;
(b) Alternatively, an order in the nature of mandamus directing the first and third respondents to cause the applicant to be released from immigration detention;
(c) In the alternative, an injunction directed against the first and third respondent [sic] prohibiting either from further detaining the applicant or pursuing his removal or deportation under any section of the Migration Act 1958.
(d) A declaration from the court that the applicant has at all times since a purported cancellation by either respondent, been a lawful non-citizen resident who holds a valid permanent residence visa allowing him to travel in and out of Australia and live permanently in Australia.
(e) In the alternative, prohibition and or an injunction preventing any of the respondents from giving effect to any purported decision to cancel the applicant's visa or affirm the cancellation of the applicant's visa or detain him on the basis of any purported decision to cancel the applicant's visa or affirm the cancellation of the applicant's visa.
(f) An order of costs against all three respondents.
10 It is not uncommon for this Court to be asked to grant a writ of habeas corpus or more commonly, as in this case, an order "in the nature of habeas corpus". There has been considerable discussion in previous cases concerning the Court's jurisdiction to grant such relief and the jurisprudential basis for any such jurisdiction: see generally Ruddock v Vardarlis (2001) 110 FCR 491; Minister for Immigration and Multicultural and Indigenous Affairs v Al Masri (2003) 126 FCR 54; Alsalih v Manager, Baxter Immigration Detention Facility [2004] 136 FCR 291 and Al-Kateb v Godwin (2004) 219 CLR 562 at [24]-[28] per Gleeson CJ (dissenting). It unnecessary for me to discuss the issue except to say that, in so far as the remedy of habeas corpus is directed to relief from unlawful imprisonment, this Court has jurisdiction in relation to an officer of the Commonwealth both to determine if detention is lawful and to order a person's release when it is not lawful; Judiciary Act 1903 (Cth) s 39B; Federal Court of Australia Act 1976 (Cth) s 22; Alsalih at [41]-[42], Sargeson v Chief of Army (2005) 225 ALR 249 at [37]-[39]. The critical issue is, however, that the detention be unlawful. The availability of the remedies sought in paragraphs (b), (c) and (d) also depends upon a successful challenge to the decision to cancel the applicant's visa. Consequently, the only substantive issue before me is whether this Court has jurisdiction to review that decision in any way and, if so, whether the present application is an abuse of process.
