3 By this proposed exception, Ms Cowell seeks to have it made clear that she would not contravene the injunction or undertaking (as the case may be) by using information published in The Age, The Sunday Age or The Australian Financial Review, even though that information might contain some of the information referred to in the schedule to the amended statement of claim, in respect of which the parties have for present purposes proceeded on the basis that there is an arguable case of confidentiality.
4 Although it is true to characterise this as opening a new issue - in the sense it was not agitated in argument on 26 and 27 February, and it was not foreshadowed in the formal order or undertaking thus proposed by either party - if I thought that the proposition were correct for the purpose of interim relief, I would not decline to consider it on that basis.
5 In considering it, it is important to bear in mind that I am dealing only with the question of interim preservation of the position, pending a more detailed interlocutory hearing which will now take place in the Supreme Court of Victoria, in which both parties will have the opportunity to adduce evidence, and there will be a far more detailed investigation of the evidence than there has been at this stage. I also bear in mind, as I indicated in the previous judgment, that in a confidential information case, once a serious question to be tried is established or conceded, the balance of convenience will usually favour preservation of the status quo to the greatest possible extent, since once a breach of confidence is exploited, it cannot later be recaptured. The damage is already done, irretrievably, when confidential information is exploited pending a final hearing.
6 The injunction proposed in paragraph 33 of my previous judgment was limited to the information referred to in the schedule to the amended statement of claim. It may well be that some of that information is in the public domain, but if it is, it is because of the course of events which I describe in the background section of my previous judgment: in particular, it came to a journalist at The Age, and later to a journalist at The Australian Financial Review, through the hands of Mr Rush and Slater & Gordon. Mr Rush was counsel, and Slater & Gordon were solicitors, acting for Ms Cowell in the McCabe proceedings. It cannot be said on the evidence presently available whether Ms Cowell was or was not privy to the decision to pass that information to the press, but the persons who passed the information to the press were her lawyers. So far as the passage of the information to the Attorney-General of Victoria is concerned, a letter, the date of which has not been clarified, from Slater & Gordon to the Victorian Attorney-General providing the information, asserted that the firm wrote on behalf of the family of the late Rolah McCabe. But even if as I am content to assume for present purposes, Ms Cowell was not privy, in the sense of having personal prior knowledge or involvement in any decision to pass the information to the press, there is at least a serious possibility that on an interlocutory hearing it might be established that in passing that information to the press Mr Rush and Messrs Slater & Gordon were acting as her counsel and solicitors.
7 In those circumstances it is at least seriously arguable that equity would regard it as unconscionable for Ms Cowell to be able to use that information for her own benefit, including for the purpose of informing her decision whether or not to commence the Reopening Proceedings, when the only reason she might be able to use it is that it is in the public domain, and the only way in which it got into the public domain was that her counsel or solicitors had put it there.
8 Mr Merkel QC has referred to the judgment of Lord Denning in Seagar v Copydex Ltd [1967] 1 WLR 923, which I cited in my previous judgment, for the distinction between use of information already in the public domain (which a confidee was at liberty to do) and use of information not in the public domain (which a confidee was not). However, Lord Denning was not concerned with a situation in which the information in the public domain had got there wholly and solely because of a breach of confidence or publication by the very person who now sought to use it.
9 In Attorney-General (UK) v Heinemann Publishers Australia Pty Ltd (1987) 8 NSWLR 341, the well-known Spycatcher case, Powell J in this Court said (at 374):
Further, while I accept that it is not every publication of otherwise confidential information which robs that information of its confidential quality ( David Syme & Co Ltd v General Motors-Holdens Ltd ), and while I accept that, in at least some of the cases (as, for example, O Mustad & Son v S Allock & Co Ltd and Dosen ) it is the fact of publication by the person to whom the duty of confidentiality has been owed which has been held to rob information of its confidentiality, the views expressed by Mason J, as he then was, in Commonwealth of Australia v John Fairfax & Sons Ltd and Commonwealth of Australia v Walsh would indicate that, providing that the subject information has been sufficiently widely published, that information was properly to be regarded as being in the public domain, and, thus, no longer confidential, even though the publication was neither authorised, or acquiesced in, by the person to whom the duty of confidentiality was owed. Finally, it seems to me that, even if, in order that information might be held to have been robbed of its confidential quality, it must be shown that the publication of that information was authorised or acquiesced in by the person to whom the duty of confidentiality was owed, it can, in this case, be said of a great deal, if not of all, of the information contained in Mr Wright's manuscript, not only, that it has previously been published, but that that prior publication has, at least in one case, been authorised, and, in other cases, has, at least been acquiesced in.
