"While I would not go so far as to classify the discovery process undertaken by News as deliberately evasive, as submitted by Counsel for Seven, there is a real concern that sufficient attention has not been paid to the great importance of ensuring that discovery is made on a proper, reliable and sound basis. In the present case, approximately one third of the claims for privilege in respect of documents originally said to be privileged have been withdrawn. This, in itself, casts some doubt on the discovery process as a whole. Indeed, the position is that the affidavit of Mr Brodie, which is the only affidavit verifying the list of documents and the claim for privilege, is so unsatisfactory that there is in effect no relevant affidavit verifying the discovery in accordance with the FCR or otherwise."
25 The evidence establishes that the original privilege claims were not made on a reliable and sound basis. Over one half of the claims of privilege in respect of documents originally said to be privileged were withdrawn. This, in itself, casts some doubt on the privilege claim as a whole. Numerous documents over which privilege had been claimed were not produced to Walker until a few weeks before the hearing of the privilege dispute.
26 However, I think that all this had passed into history and the parties became focussed on the 66 documents remaining in dispute by, say, 15 August 2008. The privilege claim in relation to those disputed documents was unlikely, I think, to have been able to be determined except by the Court even if the Department's handling of its privilege claim had been impeccable. I conclude that the Department should be awarded costs from 15 August 2008. However, I do not consider that the Department should have all its costs from that date given the measure of success that Walker enjoyed.
