21 In Interchase Corporation Ltd (in liq) v Grosvenor Hill (Queensland) Pty Ltd (No 2) [1999] 1 Qd R 163 the appellant made disclosure of an expert valuation report which was not privileged. The appellant claimed legal professional privilege in relation to other documents related to that valuation. The documents for which privilege were claimed were identified by three elements: a range of dates applicable to them, the marking of each document with a letter, and the marking of each document with a number. De Jersey J, with whom Pincus JA and Thomas J agreed, held that the identification will be sufficient if it will facilitate the production of a particular document for which the privilege has been claimed, in the event, for example, of a cesser of the privilege or should the court order production upon a ruling that the privilege does not in fact attach (170). The court rejected the submission that the purpose of the identification was to facilitate an examination by the other party, the recipient of the affidavit of disclosure, of the validity of the claim of privilege. De Jersey J said that one difficulty about requiring any identification of the nature of the document, beyond the sworn assertion of the general ground of privilege, is that the further identification could involve a degree of disclosure which could detract from the very privilege against production being claimed (170).
