Consideration
101 In Minister for Immigration and Citizenship v Li (2013) 249 CLR 332 the plurality of the High Court (Hayne, Kiefel and Bell JJ) said at [63] that the legislature is taken to intend that a discretionary power contained in a statute will be exercised reasonably and at [67] that the legal standard of reasonableness must be the standard indicated by the true construction of the statute conferring the discretion. At [71] their Honours, after referring to the judgment of Lord Diplock in Secretary of State for Education and Science v Tameside Metropolitan Borough Council [1977] AC 1014 at 1064, observed that this, namely the observations of Lord Diplock, reflects the requirement of the law that a "decision-maker understand his or her statutory powers or obligations" and continued:
It is evident in the more specific errors, going to jurisdiction, which the law recognises and to which Lord Greene MR referred in Wednesbury, such as misdirecting oneself as to the operation of the statute, taking into account irrelevant considerations or failing to take into account relevant considerations.

102 Their Honours held at [72]:
Whether a decision-maker be regarded, by reference to the scope and purpose of the statute, as having committed a particular error in reasoning, given disproportionate weight to some factor or reasoned illogically or irrationally, the final conclusion will be in each case that the decision-maker has been unreasonable in a legal sense.
103 But it is not every identifiable error in the reasoning of a decision maker that is legally unreasonable. In Minister for Immigration and Border Protection v Singh (2014) 231 FCR 437 a Full Court of this Court (Allsop CJ, Robertson and Mortimer JJ) at [44] explained the reasoning in Li as follows:
In Li, the judgments identify two different contexts in which the concept is employed. Legal unreasonableness can be a conclusion reached by a supervising court after the identification of an underlying jurisdictional error in the decision-making process: Li at [27]-[28] per French CJ, at [72] per Hayne, Kiefel and Bell JJ; cf Minister for Immigration and Citizenship v SZMDS (2010) 240 CLR 611 at [39] per Gummow A-CJ and Kiefel J. However, legal unreasonableness can also be outcome focused, without necessarily identifying another underlying jurisdictional error. The latter occurs in what French CJ (in Li at [28]) calls "an area of decisional freedom": it has the character of a choice that is arbitrary, capricious or without "common sense". See also the plurality at [66] referring to an area within which a decision-maker has a genuinely free discretion. The plurality in Li described this as an inference to be drawn because the Court cannot identify how the decision was arrived at. In those circumstances, the exercise of power is seen by the supervising court as lacking "an evident and intelligible justification".
104 In Minister for Immigration and Border Proteciton v Stretton (2016) 237 FCR 1, Allsop CJ said the following about legal unreasonableness at [6], [8] and [11]-[12]:
6 Each of the judgments in Li sought to give explanatory content to the concept of legal unreasonableness. As was discussed in Minister for Immigration and Border Protection v Singh (2014) 231 FCR 437, the judgments in Li identified two different contexts in which the concept of legal unreasonableness was employed: a conclusion after the identification of jurisdictional error for a recognised species of error, and an "outcome focused" conclusion without any specific jurisdictional error being identified: Singh at [44].
…
8 The content of the concept of legal unreasonableness is derived in significant part from the necessarily limited task of judicial review. The concept does not provide a vehicle for the Court to remake the decision according to its view as to reasonableness (by implication thereby finding a contrary view unreasonable). Parliament has conferred the power on the decision-maker. The Court's function is a supervisory one as to legality: see Li at [30], [66] and [105].
…
11 The boundaries of power may be difficult to define. The evaluation of whether a decision was made within those boundaries is conducted by reference to the relevant statute, its terms, scope and purpose, such of the values to which I have referred as are relevant and any other values explicit or implicit in the statute. The weight and relevance of any relevant values will be approached by reference to the statutory source of the power in question. The task is not definitional, but one of characterisation: the decision is to be evaluated, and a conclusion reached as to whether it has the character of being unreasonable, in sufficiently lacking rational foundation, or an evident or intelligible justification, or in being plainly unjust, arbitrary, capricious, or lacking common sense having regard to the terms, scope and purpose of the statutory source of the power, such that it cannot be said to be within the range of possible lawful outcomes as an exercise of that power. The descriptions of the lack of quality used above are not exhaustive or definitional, they are explanations or explications of legal unreasonableness, of going beyond the source of power.
12 Crucial to remember, however, is that the task for the Court is not to assess what it thinks is reasonable and thereby conclude (as if in an appeal concerning breach of duty of care) that any other view displays error; rather, the task is to evaluate the quality of the decision, by reference to the statutory source of the power and thus, from its scope, purpose and objects to assess whether it is lawful. The undertaking of that task may see the decision characterised as legally unreasonable whether because of specific identifiable jurisdictional error, or the conclusion or outcome reached, or the reasoning process utilised.
105 As is clear from Li and, as the applicant contends, the statutory scheme under which the decision is made, here the ASIO Act, is relevant to a determination of the standard of reasonableness to be applied in making the relevant decision namely the making of the Adverse Security Assessment.
106 The terms of the ASIO Act, when read together with s 36(1B) of the Migration Act, empower the Director-General to issue an adverse security assessment when it is open to him to express a recommendation, opinion or advice on the question of whether:
it would be consistent with the requirements of security for a visa to be refused on the basis that a person is a direct or indirect risk to security; or
the requirements of security made it necessary or desirable for a visa to be refused on the basis that a person is a direct or indirect risk to security.
107 Thus, as the Director-General submitted, Parliament has empowered the Director-General to issue adverse security assessments in response to risks to security without requiring any threshold level of satisfaction or evidence beyond his conclusion that such an assessment is "consistent with the requirements of security": see the definition of "security assessment or assessment" in s 35 of the ASIO Act. It is that decision - namely that it would be consistent with the requirements of security to refuse a visa because a person is a direct or indirect risk to security - that must be shown to lack an evident and intelligible justification or to be arbitrary, capricious or without common sense.
108 In Jaffarie, Flick and Perram JJ at [72] said that caution should be exercised in any judicial exposition of what may constitute a "serious threat" to security and that such phrases must be interpreted "flexibly" but that what was required was that any "assessment on the part of ASIO that the facts constitute a 'serious threat' must be an assessment 'grounded on objectively reasonable suspicion based on evidence and in the sense that the threatened harm must be substantial rather than negligible'".
109 Both the applicant and the Director-General agreed that legal unreasonableness is fact dependent and that determining whether "an exercise of power crosses the line into legal unreasonableness will require careful evaluation of the evidence": Singh at [42]. Ordinarily, where available, the Court would examine the statement of reasons in assessing reasonableness: see Singh at [45]-[47]. However, here the Court does not have before it the classified statement of grounds but the TSOG which is subject to considerable redaction for claims for public interest immunity which are not contested by the applicant. Thus it is not possible for the Court to undertake the careful consideration of the reasons that it might ordinarily undertake in the face of an argument that the decision was legally unreasonable. The effect of the unchallenged claim for public interest immunity is, for the reasons set out at [32] to [37] above, to make the applicant's case for legal unreasonableness very difficult if not impossible to establish.
110 That this is so can be seen from the judgment of Tracey J in M46 at [87] and [90] where his Honour said:
87 The first difficulty which confronts the applicant is that the Minister had before him, not only the adverse security assessment, but also the final appreciation. It was the final appreciation which provided the Director-General with the factual foundation for his adverse security assessment. As I have already said, that document is not in evidence and it is not open to infer that it did not provide the Minister with information which could lead him, reasoning in a logical and rational way, to the conclusion that the applicant had failed the character test.
…
90 For present purposes what is important is that any finding of illogicality or irrationality giving rise to jurisdictional error must depend upon an assessment of the material which was before the decision maker. That analysis is not possible in the present case because the final assessment, on which the Minister acted, was not in evidence.
111 In circumstances where the Court only has before it the TSOG, rather than the classified statement of grounds which was before the Director-General, the Court as a practical matter only has partial knowledge of the basis of the Director-General's decision to issue the Adverse Security Assessment. In those circumstances it is, as Tracey J held in M46, not open for me to infer that the classified statement of grounds did not provide the Director-General with information that could lead him, in a logical and rational way, to the conclusion that he should issue the Adverse Security Assessment. In the same way, I could not infer that the decision to issue the Adverse Security Assessment lacked an evident and intelligible justification or that it was arbitrary, capricious or without common sense.
112 It follows that the applicant's specific complaints that certain findings in the TSOG are unreasonable cannot be made out on the state of the evidence. Even if it could be established that one or more of those findings could be impugned, it would not follow that the decision to issue the Adverse Security Assessment was unreasonable. While that conclusion means that I am not required to consider each of the findings alleged to be unreasonable I do so for completeness.
113 As to the first finding, concerning whether the applicant knew anyone called Nabil, the TSOG at [16] records that the applicant told ASIO that the only Nabil he knew was a taxi driver from Baghdad. The questioning relating to Nabil occurred at the third security assessment interview at questions 259 to 268 and 289 to 293. The applicant contends that he had not told ASIO that which was attributed to him at [16] of the TSOG. But, based on the questions and answers, in my opinion, the statement set out in TSOG [16] was open. It was an observation based on what the applicant had said in his interview. The applicant said Nabil was a taxi driver in Iraq and that he did go back to Iraq from Syria. In response to a question about whether he had any other friends he knew called Nabil in Iraq the applicant said "this is the only Nabil I know and this is his number".
114 As to the second finding, concerning Wissam and that he might sometimes be known as Abu Khattab, TSOG [27] records that the applicant said that Wissam had a son named Khattab and might sometimes be known as Abu Khattab. The questioning relating to Wissam occurred at the third security assessment interview at questions 294 to 309. Based on those questions and answers the statement included at TSOG [27] was open. It reflected what the applicant had said in the interview. In particular, the applicant:
said lots of people use Abu Khattab;
in response to a question "any of your friends?" said that he thought a friend of his had a son called Khattab but his name was Wissam not Abu Khattab; and
in response to a question "so he might call himself Abu Khattab?" answered "could be".
115 As to the third finding, concerning Ismail, the TSOG at [30] to [32] sets out matters relating to Ismail. Insofar as the TSOG records that the applicant did not mention Ismail until his second interview the applicant notes that the first interview was brought to a close prematurely. But the first interview lasted two hours and the applicant was asked whether there were any issues he wished to raise or of which he wanted to make the interviewers aware. The applicant did not, in response, raise Ismail. Accordingly, there is an intelligible foundation for the finding that the applicant "deliberately withheld information about Ismail". Insofar as the TSOG records at [32] that the applicant "implausibly claimed to not know Ismail's last name", during questioning the applicant clearly said that he did not know Ismail's full name. As to ASIO's characterisation of the applicant's evidence as implausible, that was a matter for ASIO. The Court is not permitted to engage in a review of the decision so as to remake it according to what it considers to be reasonable. There is nothing illogical or unintelligible in the characterisation of that evidence as implausible.
116 Finally, in relation to the information concerning Ismail, part of TSOG [31] is redacted on the basis of a public interest immunity claim. The extent of the redaction is not known but it follows a statement that "ASIO assesses that [the applicant's] claims about Ismail are untrue". On that basis it is not possible for the Court to infer that the conclusions drawn about Ismail are unreasonable as the Court does not know the full extent of the evidentiary basis upon which those conclusions were drawn.
117 As to the fourth finding, concerning whether the applicant is a Shia Muslim, the TSOG records at [37] that:
37. [….] ASIO assesses [the applicant's] claim to adhere to Shia Islam is false and likely part of his attempts to obfuscate inquiries into his connections to Sunni Islamic extremism which would be prejudicial to his security assessment.
(footnotes omitted)
118 There was questioning at each of the three security interviews of the applicant about his faith. The applicant's answers included a claim to be a Shia Muslim; that when he moved to Al Shaab, because his identity card said he was resident of Asamiya, a Sunni area, he encountered difficulties; that he has not visited a Mosque in Australia; and that he does not know how to pray. But the finding about the applicant's claim to adhere to Shia Muslim follows a redaction at TSOG [37]. It is thus open to infer that the finding was reached based on material other than the answers given during the security interviews and not exclusively or, indeed, at all on the information provided at those interviews. In any event the applicant did claim to be a Shiite Muslim during the interviews while maintaining he did not practice his religion. Thus, as submitted by the Director-General, to the extent the issue was whether the applicant identified as a Shia Muslim in order to obfuscate inquiries into his connections to Sunni Islamic extremism, it cannot be said that this statement or the Adverse Security Assessment was unreasonable.
