Arts 7 and 9 of the ICCPR and Indeterminate Detention
81 Both the applicant and HREOC contended that the Minister failed to take into account a relevant consideration by failing to have regard to Australia's obligations under Arts 7 and 9 of the ICCPR. In response the respondent submitted that:
"there is no general principle that the decision-maker is bound (as opposed to entitled) to take into account the terms of international treaties when exercising a statutory power. The relevant considerations … are ascertained from the terms of the statute, either expressly or by implication from its subject matter, scope and purpose."
82 I agree with the respondent that there is no "general principle" that a decision-maker is bound to consider international treaties. However, it is clearly conceivable that the "subject-matter, scope and purpose" of a particular statute may require consideration of international law and Australia's international obligations.
83 In Perez v Minister for Immigration (1999) 94 FCR 287 ("Perez"), Madgwick J considered, inter alia, the construction of ss 206 and 253(9) of the Act. His Honour referred to "two well- established principles of statutory construction" at [19]:
"First, absent clear statutory warrant, fundamental common law rights and human rights ought not be abrogated. In Wentworth v NSW Bar Association (1992) 176 CLR 239 at 252, Deane, Dawson, Toohey and Gaudron JJ said:
"There are certain matters in relation to which legislative provisions will be construed as effecting no more than is strictly required by clear words or as a matter of necessary implication. They include important common law rights, procedural and other safeguards of individual rights and freedoms."
It is trite law that preventive detention may not be judicially undertaken except with clear legislative, as well as constitutional warrant: Kable v Director of Public Prosecutions (1996) 189 CLR 51. Such detention by mere administrative fiat, not constrained by the elaborate safeguards in favour of liberty which attend judicial deprivations of liberty, should even less readily be taken to have been intended by an Australian Parliament. Secondly, legislation ought to be read, where possible, in conformity with established rules of international law and Australia's international obligations. Brennan, Deane and Dawson JJ said in Chu Kheng Lim v Minister for Immigration, Local Government and Ethnic Affairs (1992) 176 CLR 1 at 38:
"We accept the proposition that the courts should, in a case of ambiguity, favour a construction of a Commonwealth statute which accords with the obligations of Australia under an international treaty."
Although, this second principle does not lend to the importation of the terms of a treaty or convention into Australian municipal law (see Minister for Immigration and Ethnic Affairs v Teoh (1995) 183 CLR 273 per Mason CJ and Deane J and Nulyarimma v Thompson [1999] FCA 1192 per Wilcox and Whitlam JJ), it does lend support to a construction which is required under the first."
84 His Honour then quoted Art 9 of the ICCPR and held at [21]:
"It follows that, where a proposed deportation order is likely to result in administrative detention of unacceptable duration, the order may not be statutorily authorised, absent clear legislative command."
85 The Full Court in Vo differed with Perez on the issue of whether the length of detention itself could destroy the legal validity of the detention. However, the Full Court did accept that matters such as unreasonable delay and the likelihood of indeterminate detention -understood in the context of fundamental common law rights and international laws prohibiting such conduct - were matters that went to the merits of a decision under s 253(9): see Vo at [12].
86 Consequently, I consider both Perez and Vo support the proposition that in some situations international law and Australia's international obligations will be relevant considerations to the Minister's exercise of discretion under ss 206 and 253(9) of the Act. As noted above, I consider the ICCPR, which inter alia deals with the treatment of detainees, to be relevant to the decision of the Minister to continue to keep a person in detention.
87 However, as also noted above, I do not consider that the decision of 12 March 2001 had the effect of keeping Mr Luu in indeterminate detention. In Peko Walsend, Mason J held at 40:
"Not every consideration that a decision-maker is bound to take into account but fails to take into account will justify the court setting aside the impugned decision and ordering that the discretion be re-exercised according to law. A factor might be so insignificant that the failure to take it into account could not have materially affected the decision."
88 In my opinion, failure by the Minister to take Arts 7 and 9 of the ICCPR into account did not have a material affect on the Minister's decision. It is unrealistic to expect administrative decision-makers to make reference to every relevant international obligation affecting their decisions. However, if on the other hand, a decision-maker makes a decision contrary to a relevant international obligation, the decision-maker will be bound to take this international obligation into account. This must necessarily be the case, if not for any other reason than to accord procedural fairness to an applicant for acting inconsistently with their legitimate expectation (see above at [60 - 62]).
