CONCLUSIONS
75 None of the grounds of review has been made out. The applications must, therefore, be dismissed.
76 The applicants were, understandably, affronted at receiving adverse security assessments and frustrated at not knowing why such assessments had been made. They objected to the failure of the Director-General to place evidence before the Court which made it difficult, if not impossible, for them to make out the grounds of review on which they relied and prevented the Court from undertaking any meaningful judicial review of his decisions. This, it was contended, restricted the ability of the Court to control the exercise of executive power and thereby undermined the rule of law.
77 These are matters of fundamental importance to the administration of justice in this country. My reasons would not be complete were these issues to pass unnoticed.
78 The concept of the rule of law is not susceptible of strict definition. Its constituent elements, as with the concept of democracy, vary from country to country. It is not underpinned by any absolute principles which can lay claim to universal validity: see W Friedmann, Legal Theory (5th ed.) at 422.
79 Rather, the rule of law is made up of a series of principles or precepts which are of variable content and some of which need not be present in order for it to be said that the rule of law operates in a particular country. Among the principles which have long been accepted in Australia are the separation of judicial and executive power and the availability of judicial and administrative checks on the exercise of executive power.
80 Elsewhere the rule of law has been said to be based on a series of norms which guarantee the existence and independence of legal institutions and certain liberties of the citizen: see, for example, F Neumann, The Rule of Law at 9.
81 A common feature of all of these analyses is that none of the precepts, principles or norms which are relied on to advance and ensure the rule of law are said to be inviolable. Professor Rawls accepts that it may be necessary, in order to avoid social evils, for precepts to be compromised but he maintains that this should only occur to the minimum extent necessary to achieve the objective: see Rawls, A Theory of Justice, at 235-243. Professor Freidmann accepts that individual rights which are protected by the rule of law must be balanced against the individual's responsibility towards society as a whole.
82 It does not, therefore, necessarily follow that the self-imposed restraints which courts have adopted when undertaking the judicial review of security decisions, are somehow incompatible with the rule of law.
83 That is not to diminish the importance of the judicial review function in maintaining the rule of law. As Brennan J said in Woodward (at 70), judicial review "is neither more nor less than the enforcement of the rule of law over executive action; it is the means by which executive action is prevented from exceeding the powers and functions assigned to the executive by law and the interests of the individual are protected accordingly …" The importance that this Court and other courts in the common law world attach to their judicial review functions was essayed by Spender J in his reasons for decision in Haneef v Minister for Immigration and Citizenship (2007) 161 FCR 40 at 44-53. It is not consistent with the rule of law for any government agency, including security organisations, to be immune from judicial review. This truism has been articulated in many judicial pronouncements, including cases where disclosure of evidence was resisted on the grounds that such disclosure would prejudice national security: see, for example, Woodward at 55 (per Mason J), 70 (per Brennan J) and, implicitly, by the Full Court of this Court in Leghaei.
84 Whilst asserting the right of the judicial arm to review decisions made by security agencies, the courts have acknowledged the need for a cautious approach lest their actions might harm national security interests. They have also recognised, without deferring absolutely to any relevant security agency, that such agencies are usually better placed to assess the impact of disclosure of particular material than are the courts.
85 In Alister v R (1984) 154 CLR 404 at 435 Wilson and Dawson JJ said that:
"The outstanding feature of the claim to immunity is the nature of the public interest which the Minister seeks to protect. Questions of national security naturally raise issues of great importance, issues which will seldom be wholly within the competence of a court to evaluation. It goes without saying in these circumstances that very considerable weight must attach to the view of what national security requires as is expressed by the responsible Minister."
In that case (at 455) Brennan J said that a court is "ill equipped itself to evaluate pieces of intelligence obtained by ASIO."
86 In Woodward (at 74) Brennan J had expanded on this observation. He asked:
"… how can the gravity of a security risk be evaluated by a court? It may be necessary to evaluate Australia's relationships with foreign countries, the stability of international affairs, the passion inspired by a particular cause or the likelihood of adherents to the cause taking violent steps in support of it; it may be necessary to evaluate rumour or suspicion as well as proof. It may be reasonable, even necessary, to determine the gravity of a risk by intuition rather than deduction. It may be truly said that the skills and procedures of a court do not fit it to find the point on the scale of gravity of every risk which may be thought to pose a threat to the Commonwealth, the States and Territories and the people thereof, and it may be accepted that a court will not necessarily have or be able to obtain all the evidence needed to allow it to quantify a risk precisely. However, it does not follow that judicial review is excluded."
See statements to like effect in the judgment of Hayne J in Thomas v Mowbray (2007) 233 CLR 307 at 477.
87 In Leghaei, the Full Court quoted with approval the observations of Lord Nicholls in A v Secretary of State for the Home Department [2005] 2 AC 68 at 128 where his Lordship said that:
"All courts are very much aware of the heavy burden, resting on the elected government and not the judiciary, to protect the security of this country and all who live here. All Courts are acutely conscious that the government alone is able to evaluate and decide what counter-terrorism steps are needed. … Courts are not equipped to make such decisions, nor are they charged with that responsibility."
88 The cautious approach which is reflected in these decisions has a number of implications for the exercise of the power of judicial review of decisions which, it is claimed, have been based on intelligence and other sensitive information.
89 The first is that the courts will give "very considerable weight" to the agency's view of what national security requires in any particular instance: see Alister at 435 (per Wilson and Dawson JJ). This dictum was applied by the Full Court in Leghaei when dealing with an adverse security assessment, made under the ASIO Act: see at 147. That is not to say that the Court must, in all cases, accept the security organisation's assessment. Such deference is, however, an acknowledgement of the practical difficulty faced by a court in evaluating evidence adduced in support of public interest immunity claims on the grounds of harm to national security.
90 Faced with this difficulty Australian courts have stressed that those whose evidence is relied on to make good a claim that disclosure of information would be contrary to the national interest bear a heavy burden and have insisted that decision-makers must give "personal genuine consideration" to the competing interests which are involved when such a claim is made: see Leghaei at 148.
91 Courts have always been sensitive to the necessity of avoiding decision-making on the merits when undertaking judicial review: see Peko-Wallsend at 40-41 (per Mason J). This sensitivity has been particularly acute when dealing with challenges to decisions made on security grounds. In Woodward (at 54) Gibbs CJ said that "the…argument that ASIO may not characterise a person as a security risk unless he is in fact a risk finds no support in the provisions of the Act … and if accepted would, in effect, give a right of appeal from conclusions formed by officers of ASIO." Mason J added (at 63) that:
"And the further allegations … that the appellants are not and have not been at any material time a security risk does not answer the problem. I have already pointed out that, although a person is not in fact a security risk, ASIO may well have reasonable grounds, based on information it receives, for believing or suspecting that he is."
92 A final implication has already been adverted to, namely, that security considerations may effectively reduce to a bare minimum the obligations of procedural fairness which fall on decision-makers.
93 Sundberg J was alert to all of these matters when he considered and ruled on the Director-General's claim for public interest immunity. He examined the assessments and the reasons for them and the evidence put forward by the Director-General in support of the claim. Once that claim was upheld, the unavoidable consequence was that the Director-General's reasons could not be disclosed to the applicants, their legal advisors or the Court. As his Honour said (at 511):
"In seeking to establish an exceptional case the applicants point out that they may be unable to make out their cases if the claim to immunity is upheld. The authorities establish that this consequence of the outcome of the process of balancing public interest immunity against the public interest, upon which the applicants rely, of having conventional access to evidentiary material, is not exceptional."
In this passage his Honour anticipated what has now come to pass.
