An objective test or a process of evaluation?
90 A final point of dispute that arises on the proper construction of s 501(6)(h) (set out at [64] above) focusses on the significance to be given to the word "reasonable". The two competing positions can be summarised as follows:
(1) The submission of the appellant in FUD18 (endorsed by the respondent to the current appeal in oral submissions) was that s 501(6)(h) poses an objective question, namely: is it is reasonable to infer from the Interpol notice that the person would present a risk to the Australian community or a segment it? The consequence being that any inference drawn by the Minister must be based on the existence of facts which are sufficient to induce that state of mind in a reasonable person (objective reasonableness).
(2) The submission of the Minister was that s 501(6)(h), read with s 501(1), calls for the Minister to engage in an evaluative exercise as to whether the Minister is subjectively satisfied of the existence of a certain state of affairs, that is, he must ask himself: am I satisfied that it is reasonable to infer from the notice that the person would present a risk to the Australian community or a segment of it? The consequence being that for there to be jurisdictional error, the evaluation of the Minister must be one that is beyond the boundaries of a lawful decision because it is lacking rationality or an intelligible justification, such that it can be characterised as being legally unreasonable (legal unreasonableness).
91 The distinction is subtle but may be one of significance in an individual case. This, however, is not such a case. That is because we have concluded that the Minister's reasons fail the test of objective reasonableness and are legally unreasonable, meaning it is unnecessary to form a concluded view on this issue. But a few observations may be made.
92 While initially it might be thought surprising that the Act imports notions of objective reasonableness, the weight of considerations appear to support such a conclusion.
93 First, the core argument of the Minister, namely that s 501(1) imports a subjective element into the interpretation of s 501(6)(h) is not compelling. It is well established that while ss 501(1) and 501(6) must be read together, their operation is temporally distinct: s 501(6) must be assessed prior to the Minister reaching a level of satisfaction required by s 501(1). This is because s 501(6) provides a complete statement as to when a person does not pass the character test, and unless one of those circumstances is enlivened, the person is taken to have satisfied the character test, at which point the discretion embodied in s 501(1) has no work to do: Makasa (at 207-8 [34]-[40] per Kiefel CJ, Gageler, Keane, Gordon and Edelman JJ). Therefore, s 501(1) cannot be said to inject an element of subjectivity into the construction of 501(6)(h).
94 Secondly, whether an element of subjectivity can be sourced from the terms of s 501(6)(h) itself is similarly questionable when one considers the use of the term "reasonable" in the section and applies the High Court's reasoning in George v Rockett (1990) 170 CLR 104.
95 Section 501(6) provides for a number of circumstances in which a person will not pass the character test. Some are satisfied by the presence of an objectively identifiable factoid (subss (a), (aa), (ab), (e), (f) and (g)), while others call for the Minister to engage in an assessment in order to determine whether the person satisfies a certain criterion (subs (b), (ba), (c), (d)). Subsection (h) is unique in this regard. On the one hand, it calls for an assessment to be made (ie, the drawing of an inference), while on the other hand, it stipulates such assessment must be "reasonable". Further, unlike subs (ba), which provides that a person does not pass the character test if "the Minister reasonably suspects that the person has" engaged in certain conduct (terms which introduce an element of subjectivity), subs (h) talks in terms of the assessment being "reasonable" at large.
96 This is where the High Court's reasoning in George becomes relevant. George concerned the issue of a search warrant by a stipendiary magistrate. The relevant statute required a justice to whom an application for a search warrant was made to satisfy himself that the conditions for the issue of the warrant were fulfilled. The matters which had to be made to appear to the issuing justice had to appear on complaint made on oath and had to contain sufficient facts to found the reasonable suspicion and reasonable belief. Critically, Mason CJ, Brennan, Deane, Dawson, Toohey, Gaudron and McHugh JJ stated that (at 112):
When a statute prescribes that there must be "reasonable grounds" for a state of mind - including suspicion and belief - it requires the existence of facts which are sufficient to induce that state of mind in a reasonable person. That was the point of Lord Atkin's famous, and now orthodox, dissent in Liversidge v Anderson [[1942] AC 206] … Therefore it must appear to the issuing justice, not merely to the person seeking the search warrant, that reasonable grounds for the relevant suspicion and belief exist.
97 It is arguable that George stands for the proposition that where legislation, such as the legislation in this case, prescribes a requirement that a state of satisfaction be "reasonable", the role of the Court on review is to determine for itself, on the basis of the documents to which the decision-maker was authorised to have regard, whether that state of mind is reasonable. This is supported by the way in which the High Court has since applied the reasoning in George. For present purposes, two examples will suffice.
98 In McKinnon v Secretary, Department of Treasury [2006] HCA 45; (2006) 228 CLR 423, the question for determination was whether there existed reasonable grounds for the claim that disclosure of a document would be contrary to the public interest. Gleeson CJ and Kirby J, after endorsing the reasoning of the Court in George, stated (at 429-30 [10]-[12]):
10. … [T]he point of the objectivity of such a test, when it is necessary to consider whether a primary decision-maker had reasonable grounds for a given state of mind, is that the question is not whether the primary decision-maker thinks he or she has reasonable grounds.
11. To decide whether it was reasonably open to a decision-maker, on the evidence, to make a judgment such as a decision whether a person was (or was not) negligent, or whether the known facts are sufficient to induce in a reasonable person a suspicion or belief that someone is guilty of a crime, or whether there are reasonable grounds for a claim that a course of action (such as disclosure of a document) would be contrary to the public interest, involves an evaluation of the known facts, circumstances and considerations which may bear rationally upon the issue in question. …
12. Where a claim, or an argument, or a conclusion or some other state of mind (such as suspicion, or belief, or satisfaction) involves an interplay of observation (of objective facts and circumstances), opinion, and judgment (which may involve an evaluation of matters such as reasonableness of conduct, or of the public interest), the question whether there are reasonable grounds for such a claim, or argument, or state of mind requires a consideration of all relevant matters and an assessment of the reasonableness of the claim, or argument, or state of mind having regard to all relevant considerations. Suppose the question is whether there are reasonable grounds for suspecting that A killed B. Suppose that A is a person of violent propensity, who had a motive to kill B, and had declared an intention to do so. Let it be assumed that those three facts are incontestable. In the absence of any other facts they may lead to a conclusion that there are reasonable grounds for suspecting that A killed B. Suppose, however, that A has an undisputed alibi. The first three facts then cease to constitute reasonable grounds for the suspicion. The question cannot be answered without considering all four facts. It is not a hypothetical question. It is a question to be answered in the light of all the known circumstances. This applies to all relevant considerations whether they be matters of objective fact (as in the example given), or of opinion, or of argument. Until all relevant considerations, that is, all (known) considerations that could have a rational bearing upon the claim, or state of mind, or decision under review, are taken into account, it is impossible to form a just and fair judgment whether, objectively considered, there are reasonable grounds for the claim that the disclosure of the document would be contrary to the public interest. It is not enough for the Tribunal to ask whether there are facts, or opinions, or arguments that rationally bear upon that topic. All relevant matters must be taken into account; not for the purpose of deciding whether the Tribunal agrees with the Minister, but for the more limited purpose of deciding whether there are reasonable grounds for the claim which the Minister accepted.
99 Further, in Prior v Mole [2017] HCA 10; (2017) 261 CLR 265, which involved the consideration of a power conditioned on a member of the state police force having reasonable grounds for believing that, because of a person's intoxication, he or she may cause harm to himself or herself or someone else, all members of the Court considered the existence of the power to be conditioned upon proof of facts and circumstances sufficient to induce in the mind of a reasonable person a positive inclination towards acceptance of the subject matter of the belief: see 270 [4] per Kiefel and Bell JJ, at 277 [23]-[24] per Gageler J, at 292 [73] per Nettle J, and at 298 [98]-[101] per Gordon J. Indeed, it could be said in the current case that the state of satisfaction required to draw an inference is higher than that required to found a mere suspicion or belief, as was required in George.
100 Thirdly, it is a well-accepted principle of construction that a Court must strive to give effect to every word of a provision and every provision of an Act: see Commonwealth v Baume (1905) 2 CLR 405 (at 415 per Griffiths CJ, and at 419 per O'Connor J); Plaintiff M70/2011 v Minister for Immigration and Citizenship [2011] HCA 32; (2011) 244 CLR 144 (at 192 [97] per Gummow, Hayne, Crennan and Bell JJ). This is grounded in the principle that an Act is to be construed as a whole and that it is "improbable that the framers of legislation could have intended to insert a provision which has virtually no practical effect": Minister of State for Resources v Dover Fisheries Pty Ltd (1993) 43 FCR 565 (at 574 per Gummow J, with whom Hill and Cooper JJ agreed). A corollary to this is that it may be the case that other provisions of a statute reveal that a particular expression in one provision is to have a meaning which is broader or narrower than might at first glance be thought: see Ross v The Queen (1979) 141 CLR 432 (at 440 per Gibbs CJ, with whom Barwick, Stephen, Mason and Aickin JJ agreed).
101 Here, a crucial provision of the Act is s 501(6)(d)(v), which is in the following terms:
(6) For the purposes of this section, a person does not pass the character test if:
…
(d) in the event the person were allowed to enter or to remain in Australia, there is a risk that the person would:
…
(v) represent a danger to the Australian community or to a segment of that community, whether by way of being liable to become involved in activities that are disruptive to, or in violence threatening harm to, that community or segment, or in any other way;
102 If it were the case that both subss (d)(v) and (h) require the Minister to engage in a subjective assessment of the risk posed by an individual to the Australian community, then, as was prefaced above, the operation of s 501(6)(h) would be rendered somewhat superfluous. That is because there is nothing in subs (d)(v) preventing the Minister from taking an Interpol notice into account when assessing whether a person represents a danger to the Australian community or a segment of it. The better view is to give subs (6)(h) distinct work to do in the character test, and that is done by understanding the provision to pose a test of objective reasonableness.
103 Fourthly, this understanding is furthered by giving weight to the Explanatory Memorandum to the Bill inserting s 501(6)(h), which notes (at [55]) that the insertion of subss (6)(g)-(h):
… ensure that a person objectively does not pass the character test if either of these provisions apply to them, without the need to further assess them against the subjective criteria in subsection 501(6) of the [Act].
(Emphasis added).
104 Therefore, while it is unnecessary in the present case to come to a concluded view on this element of the construction of s 501(6)(h), there is much to be said for the view that s 501(6)(h) poses a test of objective reasonableness.
105 For completeness, we note that in the current circumstances it is also unnecessary to express a view on whether the reasoning of the Full Court in Taulahi v Minister for Immigration and Border Protection [2016] FCAFC 177; (2016) 246 FCR 146 (at 181-2 [142]-[144] per Kenny, Flick and Griffiths JJ) means that the principle of legality should apply to the construction of s 501(6)(h) of the Act.
