(i) The prison governors' authority to hold an immigration detainee
82 While immigration detainees are ex hypothesi not lawfully in Australia, they nevertheless have the protection of Australian law as well as liabilities under it. Nobody may be deprived of his or her freedom unless a statute or the common law authorises it. Legislation should be jealously interpreted against unnecessary or unclear implication of such authority.
83 It is however the case that the very notion of compulsory detention of people implies, as a matter of practical necessity, that those responsible for the detention should have sufficient power to change the nature and place of the detention as circumstances require. Possible threats to good order in, and the safety of other people at, the place of detention are but one of the circumstances that show that necessity. Considerations of the health or welfare of a particular detainee are other examples. Perceived threats to the safety and good order of an institution may be incapable of legal proof and may need to be dealt with promptly. There might be many instances in which it is practically necessary to detain an unlawful non-citizen in a prison, notably the unavailability of suitably secure accommodation subject to administration by persons under a strict duty themselves to behave properly. Those circumstances are not limited to the initial detention of such a person. It is not to be thought that the Parliament intended that officers placed under a duty to detain people in immigration detention should lack the power, when bona fide thought necessary, to arrange for a person not initially detained in a prison later to be so detained.
84 Prisons in Australia are established and operated under the auspices of the States and Territories and laws made by them. They are staffed by governmental officers or employees or by employees of private contractors subject to strict standards and legal controls. In all cases, there are standards and public expectations of decent food and health care, secure accommodation of sufficient modest comfort, and effective but fair disciplinary systems and administrative procedures.
85 It is in this setting that the intention to be imputed to the Parliament by its adoption of the phrase "in a prison or remand centre of the Commonwealth, a State or a Territory" falls for determination. If the phrase is interpreted to mean only that an officer may arrange that a detainee be held within, and in that sense "in", the physical boundaries of a place that is a prison or remand centre, but that the phrase was not intended to confer authority on the officer to have the detainee made subject to the control of the ordinary prison etc authorities, then the applicant's argument would succeed. But the consequences would include that the detaining officer or his/her supervisors would need urgently to arrange for other "officers" to detain the person within such boundaries or to have pre-arranged facilities for this. This would make urgent detention in a prison etc quite impossible in many cases. In my opinion, such an inconvenient result, possibly including threats to peace and good order, or prejudice to the health or welfare of the subject detainee, should not be imputed as the parliamentary approach.
86 The matter may also be viewed in another way. It is clear that immigration detainees are subjected to a liability that may include detention in a prison or remand centre. Such institutions are not only places, they are institutions and they are run in particular and well-understood ways. How strange it would be that detainees might be so liable yet, as the applicant urges, have a right without more, to sue the public officials (or their private enterprise contractual aides) engaged in so running such institutions. The Parliament should not be taken to have authorised such a thing. In my opinion the Act should be interpreted as necessarily depriving the detainee of any such rights and as granting the otherwise lawful gaolers in the prisons and remand centres immunity from any such suit. The latter would remain liable of course for any otherwise illegal maltreatment of a detainee. This view better accords generally with the approach taken in Behrooz v Secretary, Department of Immigration and Multicultural and Indigenous Affairs (2004) 219 CLR 486 to a different but analogous problem.
87 On this view, the provisions of the Correctional Centres Act, if they would otherwise have anything to do with the case, have no relevant application. I doubt that, in any event, they do. In the ordinary case of imprisonment or remand in custody, it is the law as to penal confinement and the criminal process (or as to mental health or the like) not the prisons legislation, which gives the judge etc the power to order a deprivation of liberty. It is the order of the judge or other official which has the effect of the deprivation of the subject person's right to liberty and which authorises the executive arm of government to implement such deprivation. The warrants that are usually issued by courts serve simply to assure the relevant executive officers (or other persons with an interest in the matter) that such an order has been made. Section 39 of the Correctional Centres Act and its succeeding sections in Part 8 are concerned with fixing the identity of the executive officers charged, from time to time, with giving effect to a court's order, and otherwise indicating merely how it is to be implemented, including, under s 46, by giving immunity from suit for bona fide purported performance of acts that the statute contemplates.
88 In that context there is no need, in the interests of vindicating the presumption against statutory interference with liberty (or otherwise), to read the concept "or other competent authority" in the s 4 definition of "inmate" in the Correctional Centres Act as being limited to authorities of the same kinds as are referred to in the preceding words, namely persons acting at least quasi-judicially. It seems more likely that the framers of that legislation intended to "make a fresh start" by employing those words (to adopt a phrase from Chancery: Re Commonwealth Oil Corp Ltd [1917] 1 Ch 404 at 412-3), to provide a general, catch-all description of all authorities of whatever kind that were competent to require the detention of a person in a prison or remand centre.
89 The liability of the detainee to detention in a prison etc, has its source in the determination of the relevant Migration Act officer that that should be so. Necessarily that determination will be communicated to the detainee. A detainee in New South Wales so liable was, in 1999, reasonably enough described as a "person ordered to be imprisoned in or committed to a correctional centre … by [a] competent authority". The s 46 immunity from suit provisions would avail the governor. If he/she was immune, so was the Commonwealth if its "officer" lawfully caused the governor to imprison the detainee.
