18 Young was a decision of the Court of Criminal Appeal of this State which held that the common law did not recognise a category of public interest immunity relating to sexual assault counseling. In so concluding, the Court (by majority) held that public interest immunity is concerned only with the conduct of governmental functions (see at 693 [57], 695 [65] per Spigelman CJ with whose reasons on this matter Abadee, James and Barr JJ agreed). It is not clear whether their Honours intended to confine this reference to the executive arm of government (cf per Spigelman CJ at [57]). Beazley JA dissented.
19 I must say, with the profoundest respect to their Honours in the majority, that I have difficulty in appreciating the basis for any such governmental function restriction. Nevertheless, I would be bound to follow this considered statement of principle in any case that arose concerning the common law of public interest immunity. This said, D v National Society for the Prevention of Cruelty to Children [1978] AC 170 demonstrates, at the very least, that the notion of governmental function is very broad in nature (see also the professional discipline cases cited in Young at 694-5).
20 I am, however, satisfied that the resolution of the present case does not turn upon the scope or application of Young. Young's exposition of the common law has no direct and little indirect impact upon the true issues in the present appeal.
21 Young concerned the common law of public interest immunity, because the substantive proceedings before the court were criminal, and because Division 1B of the Evidence Act 1995 (which had been invoked in support of the claim for public interest immunity) did not apply directly or derivatively to the production of documents on subpoena. By contrast, the substantive proceedings in the present case are civil (see Criminal Assets Recovery Act 1990, s5) and Part 36 r13 of the Supreme Court Rules incorporates by reference those parts of the Evidence Act which address issues of public interest immunity.
22 Young's indirect application consists in the caution expressed about recognizing new categories of immunity (see esp at 696-700) and its insistence upon cogent and specific supporting evidence (see at 702-3).
23 Part 3.10, Division 1A of the Evidence Act (ss126A-126F) is particularly relevant. It deals with professional confidential relationship privilege. Section 126B empowers a court to direct that evidence not be adduced in a proceeding if the court finds that adducing it would disclose a "protected confidence". The term is defined in s126A in language broad enough to include a communication made during the provision of medical treatment.
24 There is also the general exclusion of evidence of "matters of State" (broadly defined in a non-exclusive way) to be found in s130 of the Evidence Act.
25 It is unnecessary to explore the detailed scope of Division 1A which commenced operation on 1 January 1998. Nor, in light of the way this appeal was argued, is this appeal a suitable vehicle for exploring the relationship between the statutory privilege enacted therein, and the common law of public interest immunity.
26 In the present case none of these matters were drawn to the attention of the learned primary judge. The application was dealt with as though it concerned common law public interest immunity and nothing else. The evidence was similarly focused. In this Court, counsel responded as well as they were able when these matters were pointed out from the Bench; but the Court did not have the assistance of any considered submissions addressing the problems in this case through the primary lens of the relevant statutory materials.
27 The written submissions filed in the present application had effectively joined issue on the questions whether Young prevailed over Clifford and whether (if it did) there was nevertheless a sufficient "governmental" interest in safe and effective prison administration to remove any problem stemming from Young's conclusion that the common law was thus restricted. I have already indicated why these endeavours miss the point.
28 Counsel for the claimant informed the court that his submissions could be encapsulated in three broad propositions namely:
