The Submissions and their Disposition
22 Several contentions are advanced to show that there is an arguable case for the proposition that the Minister is obliged to consider the applications for protection visas prior to removing the applicants from Australia and/or that the executive itself is required to consider their applications for protection visas if the statutory framework does not apply.
23 The first contention on behalf of the applicants is that they are not at present "transitory persons" under the Act being persons who have been brought into Australia's migration zone. It is submitted that the definition of transitory person is not temporally unlimited. That is to say there must be a point of time at which a person ceases to be a transitory person notwithstanding the apparent scope of the definition. A person who is within Australia making an application for a visa, having been brought into the migration zone, is not a transitory person. This contention flies in the face of the evident purpose and meaning of the provisions of s 46B and the definition of "transitory person". That plainly contemplates that a transitory person can be in Australia and may be an applicant for a visa. In such a case that person, if an unlawful non-citizen, cannot make a valid application. The result that the application is not valid attracts the other general provisions of the Act relating to visa applications. As observed earlier, the existence of a valid application is critical to the statutory power to grant a visa.
24 The agreed facts of this case make it clear that each of the applicants is, for present purposes, to be regarded as a transitory person. They were either offshore entry persons taken to another country under s 198A within the definition in paragraph (a) of transitory person in s 5(1), or persons who were transferred to the HMAS Manoora from the MV Tampa (par (c)(i)), were then taken to Naura and to another country (par (c)(ii)) and disembarked in that country ( par (c)(iii)). It is also clear that none of them is a person who has been assessed to be a refugee for the purposes of the Refugees Convention as amended by the Refugees Protocol, whatever process is referred to by those words. To the extent that there has been any assessment it is common ground that they have been assessed not to be refugees. There is in my opinion no arguable case against the proposition that the applicants are transitory persons for the purposes of s 46B.
25 It is then contended that s 46B is not a valid exercise of the legislative power of the Commonwealth under the Constitution. This is advanced as a matter of characterisation. It is said not to be a provision which relates to the constitutional powers to make laws with respect to immigration and emigration or with respect to aliens. That argument in my opinion has no merit. Section 46B is plainly a provision directed to a subset of the class of persons seeking to enter and/or remain in Australia, being transitory persons who are in Australia and who are unlawful non-citizens. On that basis alone it is a law with respect to immigration. In any event one of the criteria of the application of s 46B(1) is that the person is an unlawful non-citizen, a class which attracts the application of the aliens power.
26 It is also said, although it does not appear in the written material, that there is an arguable proposition that the applicants are not unlawful non-citizens. They have been brought to Australia, undoubtedly with the authority of the Minister, for the purpose of giving evidence in proceedings in this country, being criminal proceedings against alleged people smugglers. The existence of an assumed ministerial consent is linked, in argument, to the words of s 29 which defines "visa" in terms of a permission to travel to and enter Australia. It is suggested that there is an argument that the Minister, in authorising their entry into Australia, has granted them a visa and that they are therefore not within the description of unlawful non-citizens. Again, the argument has no merit. The grant of a visa is a procedure which requires that an application be made by an applicant. It has to be a valid application, it has to be for a specified class of visa and the visa can only be granted according to prescribed criteria. The bringing of persons from outside Australia to within Australia under the provisions of s 198B, which it appears would authorise the involuntary movement of persons to this country from another country, does not constitute or involve the grant of a visa. Nor is there any statutory road by which it can effect the grant of a visa or the applicants' transformation, once in this country, into lawful non-citizens.
27 Then it is said that the second respondent has failed to take into account, as mandatory relevant considerations, its international obligations under the Convention Relating to the Status of Refugees. This is a reference to the obligations which the executive has assumed by entering into the Convention Relating to the Status of Refugees. So far as the power to grant a visa derives from statute, Australia is free to qualify or limit, under its domestic law, the way in which or indeed whether it discharges its obligations under the Convention. Those obligations bind in domestic law only to the extent that they are embodied in a domestic statute. No mandatory relevant consideration arises. In any event the only relevant obligation is the non-refoulment obligation under Article 33. It is not suggested that that obligation is breached by returning the applicants to Nauru.
28 The invocation, by the applicants, of direct executive power in relation to the grant of protection visas relies upon s 7A of the Act which was introduced into the Act last year. That section gives effect to a view expressed by the majority in Ruddock v Vadarlisthat the Act does not exclude the executive power to prevent people from entering into Australia without lawful authority and to remove people from Australia who have entered without lawful authority.
29 The applications for protection visas made, through the Minister, to the Governor‑General in Council, operate upon the assumption that there is a legal duty upon the executive to discharge the obligations assumed by Australia at international law under the Convention. It is however a well‑known principle that in this country the obligations assumed by agreements between the Australian Government and other governments, expressed in conventions and treaties, do not take effect as part of the domestic law of Australia unless given such effect by a statute passed by the Parliament. There is no legal obligation under domestic law which would be enforceable in a court upon the executive to entertain such an application. It is also suggested that by removing the applicants from Australia, as it intends to do, the Commonwealth has failed to accord procedural fairness in relation to their applications in that it has failed to consider or properly consider or provide any hearing in respect of their applications. Of course, if there is no legal obligation to consider the application, there can be no failure to accord procedural fairness.
30 An ancillary argument in this respect was that, by reference to the judgment of the High Court in Minister for Immigration and Ethnic Affairs v Teoh (1995) 183 CLR 273, there was an obligation in the exercise of executive powers to take account of Australia's obligations under the Refugee Convention. The decision of the High Court is authority for the proposition that in the exercise of a statutory discretion, a decision‑maker who intends to depart from an obligation which Australia has assumed under an international treaty should, as a matter of procedural fairness, indicate that to the person affected by the decision, so that person has an opportunity to make submissions. That is to say, there is a legitimate expectation on the part of the subject of the proposed decision that Australia will honour its obligations unless otherwise indicated. None of that is relevant here because there is no relevant statutory power to entertain the application for a protection visa and no legal obligation on the executive to entertain such an application outside the framework of statute.
