35 The respondent submitted that:
a. publication of the material would be injurious to the public interest (Gibbs ACJ in Sankey v Whitlam at 39-40);
b. the production of some of the material may reveal Cabinet deliberations inconsistently with the doctrine of collective responsibility, which may fan ill informed or capricious public or political criticism to the detriment of the business of government;
c. the costings and related workplace reforms were developed for negotiations; they may cover matters related to changes to legislation or awards and could concern staffing, human resource policies, rosters, workplace composition or work intensity in relation to savings resulting in workplace disputes;
d. the release of this material without context and background leaves them open to misinterpretation;
e. circumstances of each negotiation for each department vary; and
f. costings may relate to State owned entities in competition with private enterprise (commercial confidence information revealed).
36 On a number of occasions the High Court has pronounced on the principles to be applied in determining whether public interest immunity would attach to the documents in question:
a. The Court must balance the public interest in withholding the production of a document, against the public interest in ensuring that courts performing the functions of justice should have access to relevant evidence: Sankey v Whitlam ;
b. The balancing exercise - can only be taken when it appears that both aspects of the public interest do require consideration - that is, when it appears, on the one hand, that damage would be done to the public interest by producing the documents sought or documents of the class, and, on the other hand, that there are or are likely to be documents which contain material evidence: Alister v R at 414;
c. It is only in a case where there are quite exceptional circumstances which give rise to a significant likelihood that the public interest in the proper administration of justice outweighs the very high public interest in the confidentiality of documents recording Cabinet deliberations that it will be necessary or appropriate to order production of the documents to the court. Where such exceptional circumstances do exist, the appropriate course to be followed will ordinarily be for the judge personally to inspect the documents for the purpose of deciding whether the relevance of the material to the proceedings in which disclosure is sought is sufficient, even in those exceptional circumstances, to justify disclosure.… Having regard to the strength of the claim for immunity, a judge ought not order the disclosure of the contents of documents of that class unless the judge is satisfied that the materials are crucial to the proper determination of the proceedings: Commonwealth v Northern Land Council [1993] HCA 24; (1993) 176 CLR 604 at 619;
d. It has never been doubted that it is in the public interest that deliberations of Cabinet should remain confidential in order that the Members of Cabinet may exchange differing views and at the same time maintain the principle of collective responsibility for any decision which may be made: Northern Land Council at 615;
e. The law recognises that there is a class of documents which in the public interest should be immune from disclosure. The class includes Cabinet Minutes and Minutes of discussions between heads of departments … papers brought into existence for the purpose of preparing a submission to Cabinet … and indeed any documents which relate to the framing of government policy at a high level. According to Lord Reid, the class would extend to 'all documents concerned with policy making within departments including, it may be, minutes and the like by quite junior officials and correspondence with outside bodies': Conway v Rimmer [1968] AC 910 at 952: Sankey v Whitlam at 39-40 per Gibbs ACJ;
f. In the case of records of Cabinet deliberations, the highest degree of protection against disclosure is warranted: Northern Land Council at 617-618;
g. It is doubtful whether the disclosure of the records of Cabinet deliberations upon matters that remain current or controversial would ever be warranted in civil proceedings. The public interest in avoiding serious damage to the proper working of government at the highest level must prevail over the interests of a litigant seeking to vindicate private rights: Northern Land Council at 618;
h. The governmental process directed to obtaining a Cabinet Decision upon a matter of policy and Cabinet's Decision upon that matter should not, in the public interest, be disclosed by the production of Cabinet papers including what I would describe as papers which have been brought into existence within the governmental organisation for the purpose of preparing a submission to Cabinet. Such documents belong to a class of documents that, in my opinion, are of a nature that ought not to be examined by the Court, except, it may be, in very special circumstances: Lanyon Pty Ltd v Commonwealth [1974] HCA 11; (1974) 129 CLR 650 at 653 per Menzies J.
37 The notifier submitted that I should inspect the Cabinet Minutes and Decision for the purpose of undertaking the balancing exercise required by Sankey v Whitlam. Menzies J in Lanyon, however, was of the opinion that a court should not examine the documents except in very special circumstances.
38 I am well aware of the reasons for the notifier's desire to obtain the relevant documents. It wishes to see whether the documents will materially assist its case that at the relevant time it was government policy that agency initiatives or agency cost offsets were limited to a cap of 0.5 per cent.
