When the Court may inspect documents for itself
25 In the light of all the formulations of the principle which I have noted, it is necessary to decide on which side of the line a particular document falls. In the absence of any more specific information than is afforded by the description of the documents catalogued in Appendix A and Appendix B to these reasons, it may be appropriate to have recourse to the technique proposed by Wilcox J in Jackson v Wells, supra. In that case, his Honour was dealing with an application for review of decisions by two judges of this Court, acting as personae designatae to issue warrants under s 20 of the Telecommunications (Interception) Act 1979 (Cth). A claim to public interest immunity was advanced and supported by affidavits described by his Honour at 305-306. In the course of his reasons, his Honour went on to make what he called, at 307, "four final comments" about the proper approach to be adopted to such a claim for immunity. Three of those "comments" are relevant here, and may be summarised as follows:
· A party to a proceeding is not, where there is a clear legislative indication to the contrary, entitled as of right to see documents which have been discovered under cover of a claim of public interest immunity. A submission to the contrary, his Honour considered, was based on an inapt analogy with what occurs when documents have been seized pursuant to a search warrant which was the case in Inland Revenue Commissioners v Rossminster Ltd [1980] AC 952, to which his Honour had been referred;
· When a claim of public interest immunity is made, it will not ordinarily be appropriate to reveal the contents of the subject documents to a party's legal representatives, because (at 307-8);
It involves a number of problems. Without reflecting in any way upon the integrity of any counsel or solicitor, difficulties are likely to arise where counsel appearing in, and advising their clients in respect of, protracted and complex proceedings acquire information which they are not free to use or to pass on to their clients. During the heat of battle an unwitting disclosure may occur. Frank and full advice becomes impossible. I am aware of cases in which, for reasons such as these, experienced counsel have declined to receive information which they are not free to share with their clients. It seems to me merely commonsense to conclude that the fewer people who have access to confidential information the less is the risk of unauthorised disclosure.
· A claim of public interest immunity need not be accepted in full; a proper approach, in the appropriate case, is for the Judge before whom the claim is made to peruse for himself or herself the documents for which immunity is claimed. His Honour considered, at 308, that, in carrying out this exercise, the Judge should;
consider for [himself or her]self whether it extended unnecessarily widely, if necessary re-editing the material so as to reduce the extent of restriction on access
26 In my view, it is appropriate to take, in this case, the approach suggested by Wilcox J in Jackson. I shall therefore direct that each of the documents enumerated in Appendix A to these reasons other than those numbered 54 and 74 be delivered to my Associate in a sealed envelope or other container to allow me to examine each document to determine whether it is precluded from production by application of s 22(1) of the W P Actor by operation of the doctrine of public interest immunity. Where it is feasible in respect of a particular document, I shall edit or redact it to preserve the confidentiality of the part or parts which it would be inimical to the public interest to disclose or which contain information which is the subject of a protected disclosure or is connected with the investigation of a disclosed matter within the meaning of s 22(1) of the W P Act.
27 A similar course commends itself in respect of the documents enumerated in Appendix B to these reasons, which comprises Parts 2 and 3 of Schedule 1 to the second respondent's list of documents. Most of those documents, if immune from production at all, will, it seems from their description, derive that character from the doctrine of public interest immunity. In respect of some, particularly those in Part 3, the Court may decline to order production on the ground that it is not necessary in the sense explained at [34]-[38] below. I shall, accordingly, examine each of the documents listed in Appendix B to determine whether the second respondent should be ordered to produce it in its original, or in some edited or redacted, form. Those documents ought also, therefore, be delivered to my Associate in the same fashion as the Appendix A documents.
28 In light of the course which I have just indicated is to be taken, in respect of most of the documents enumerated in Appendix A and Appendix B to these reasons, it is unnecessary to consider the relief claimed by the applicants in paragraph 3 of their motion on notice dated 30 July 2009.
