(9) It is now beyond question that the court has power to inspect the document or documents privately: Sankey v Whitlam at 46. There is, however, a question whether the court should look at the documents for assistance in the balancing exercise, that is to say, when weighing the two conflicting aspects of the public interest. In some cases, the court might be able to determine that the public interest requires that the documents be withheld from production without inspection of the documents: see Commonwealth v Northern Land Council where it was held that documents recording the deliberations of Cabinet on topics which were current and controversial would not be disclosed except in quite exceptional circumstances. It was unnecessary in that case to inspect the documents to determine the claim for privilege. Only in cases where the ministerial affidavit demonstrates with sufficient particularity the nature and the significance of the documents both in terms of any need to preserve their confidentiality on the one hand and for the actual litigation on the other is it likely that it will be possible to reach such a conclusion: c.f. Woodhouse P in Fletcher Timber Ltd v Attorney-General at 295. In almost all other cases, an inspection will be necessary. There is a question whether the applicant for production of the document must satisfy some threshold test before the court inspects the documents. Plainly, the documents must be relevant. The question is whether any further or more stringent test is necessary. That question was examined by Gibbs CJ in Alister v The Queen [1984] HCA 85; (1984) 154 CLR 404, by Cox J in Legal Services Commission v Trotter at 84 - 85, and by Toohey J in the dissenting judgment in Commonwealth v Northern Land Council at 632-636. Reference should also be made to Conway v Rimmer, Burmah Oil Co Ltd v Bank of England; Air Canada v Secretary of State for Trade; Fletcher Timber Ltd v Attorney-General; and Middleton v State of Western Australia. As Toohey J pointed out in Commonwealth v Northern Land Council at 634 - 635, the process of discovery (in this court, the list of documents) demonstrates the existence and relevance of the documents to the issues in the action. The application for production for inspection is a usual concomitant of the process of discovery. It would seem, therefore, that where there is a claim for privilege on the ground of public interest immunity, the court should without more inspect the documents for the purpose of weighing the competing public interests.
