For convenience, I repeat par 3 in its entirety:
3. Levitt was denied entry into the casino. He had every opportunity to enter. (Sifner and Richardson statements). Detectives arrived about one hour after being called. Detectives made the statement to Sifner, "We know Levitt, he can wait".
24 The Wills memorandum is an unpolished communication from one officer to another within the corporate hierarchy of the claimant. In addition to the opening words of the memorandum, there are numerous cross-references to the letter. For example, in par 9 of his memorandum Mr Wills states:
At no time did casino staff attempt to "dress up" allegations. (Statements prove this to be true).
This is obviously an answer to the reference on page 3 of the letter to an attempt by Casino management to "dress-up the allegation that Mr Vignoli was attempting to asport the Casino's funds" . See also pars 4, 5, 6, 12. The opening two sentences of par 3 of the memorandum must be read in similar vein.
25 All of these factors explain and resolve the apparent contrariety on the face of the first two sentences of par 3 of the Wills memorandum. Accordingly, access to Mr Wills' source material for the second sentence was not reasonably necessary to enable a proper understanding of that sentence.
26 The plaintiff seeks to meet this conclusion by two alternative arguments.
27 Conceding for the purpose of argument, that the first two sentences of par 3 should be read in the way that I favour, counsel for the plaintiff argued that the power to order inspection of the witness statements was properly exercised because the statements were cited by the author of the memorandum as elucidating the second sentence. It was submitted that this was sufficient to enliven the power conferred by s126. Examples were given of hypothetical ambiguities in the meaning of the second sentence which would dissipate if the statements were produced for inspection. We were referred to the following passage in the judgment of Sackville J in Towney at 414:
In applying the standard specified by s126 of the Evidence Act, it is to be borne in mind that the expression "proper understanding" is by no means narrow. The dictionary definition of "proper" includes "complete or thorough"; the definition of "understand" includes "to apprehend clearly the character or nature of" and "to grasp the significance, implications or importance of": Macquarie Dictionary . It may or may not be correct to say that the test stated in s126 of the Evidence Act is, or appears to be, narrower than the principles governing implied waiver under the general law: cf Cross on Evidence , Aust ed, para 25300. Any precise assessment of the scope of s126 must await further decisions. However, I think it fair to say that, if a privileged document is voluntarily disclosed for forensic purposes, and a thorough apprehension or appreciation of the character, significance or implications of that document requires disclosure of source documents, otherwise protected by client legal privilege, ordinarily the test laid down by s126 of the Evidence Act will be satisfied.
28 Towney was a case quite removed from the present. An expert anthropological report had been filed in native title proceedings. It was intended to be used in evidence in support of the applicant's claim. The respondent Minister subpoenaed various documents which were the subject of client legal privilege ("the claimed documents"). The claimed documents related to advice and comments relating to the native title claim which were taken into account in the preparation of the final expert report. Sackville J proceeded on the basis that the Evidence Act 1995 (Cth) applied derivatively to the Minister's application for inspection. Applying s126, his Honour ruled that client legal privilege had been lost in the claimed documents because production of them was reasonably necessary to enable a proper understanding of the anthropological report.
29 The present case is distinguishable from Towney. First, it is clear that the final anthropological report in Towney was intended to be used in evidence in support of the applicant's native title claim. Sackville J had pointed out (correctly in my respectful view) that a court applying s126 will take into account the forensic purpose for which it is proposed to use documents voluntarily disclosed (at 412). By contrast, there is nothing to indicate any real likelihood that the claimant intends to make any forensic use of the Wills memorandum. The contrary has not been suggested. (This position may change depending upon the conduct of the litigation, but that is another question.)
30 The second point of distinction lies in the analysis to be found in Towney (at 414-417), of the claimed documents and their relationship to the anthropological report. In a number of places the final report cited or referred to the claimed documents in circumstances that showed that the privileged communications were adopted as building blocks in the formulation of the principles expounded and data summarised in the final report. The document analogically closest to the witness statements referred to in the Wills memorandum was the document described as "No 1. Sutton 1996a". This was a report by an anthropologist, Dr Sutton, which provided expert anthropological advice in relation to the applicant's claim. The Sutton document was included in the list of references recorded at the end of the report. More importantly, the report made it clear that concepts formulated by Dr Sutton had been adapted and applied in that report (see at 415).
31 I do not think that these principles can be applied to the witness statements referred to in par 3 of the Wills memorandum as I have construed that paragraph. I cannot see any real prospect that the claimant would put the memorandum into evidence. But in any event, I cannot see any need for a "complete or thorough" understanding of the second sentence of par 3 that extends beyond the plaintiff's wish to have prior access to the evidence of the two security personnel. In my view it is pure speculation that the statements would elucidate the second sentence in any way that would make it just to use s126 to override privilege.
32 Secondly, it is said that merely because this Court construes the memorandum differently to Levine J does not answer the fact that par 3 of the Wills memorandum is at least ambiguous. The portion of the judgment which is set out at par 20 above indicates that Levine J reasoned, in part, along the lines that production of the witness statements would assist in resolving the apparent ambiguity of the first two sentences. It is pointed out that the power in s126 is enlivened by the conclusion that production is "reasonably necessary" to enable a proper understanding of the document that has already been disclosed.
33 I think that there is force in this submission, although (if leave were granted) it might be incumbent upon this Court to exercise the discretion afresh in the light of its finding that the judgment below turns (at least in part) upon a misconstruction of par 3 of the Wills memorandum. What this submission does indicate very clearly is that this application relates to a discretionary decision on a matter of procedure. In that situation appellate restraint is mandated for the reasons discussed in Adam P Brown Male Fashions Pty Ltd v Philip Morris Inc (1981) 148 CLR 170 at 177.
34 The consideration persuades me that leave to appeal should be refused.
35 The Wills memorandum was discovered by the claimant when it might have been the subject of a claim of privilege. The dispute concerns the manner in which a busy trial judge exercised a discretionary power (effectively to require production) in aid of another procedural power (the power to order the fuller answer to an interrogatory). The "prejudice" suffered by the claimant is the early disclosure of statements of witnesses who are likely to be called at the trial.
36 The claimant submitted that production of the whole of the witness statements should not have been required without the judge first inspecting the documents to separate immaterial parts. I have no difficulty accepting the claimant's argument that the mere reference to a privileged source document, of itself, does not necessarily result in loss of the privilege attaching the whole of that source document (see Towney at 414, 416). But in circumstances where the matter was fought below on an "all or nothing" basis, I would not find appealable error in a trial judge applying s126 in similar manner. This was not a case where the trial judge was invited to examine the statements.
37 Jordan CJ's oft-repeated obiter dicta in In the Will of F B Gilbert (deceased) (1946) 46 SR(NSW) 318 at 323 bears repeating:
…there is a material difference between an exercise of discretion on a point of practice or procedure and an exercise of discretion which determines substantive rights. In the former class of case, if a tight rein were not kept upon interference with the orders of Judges of first instance, the result would be disastrous to the proper administration of justice The disposal of cases could be delayed interminably, and costs heaped up indefinitely, if a litigant with a long purse or a litigious disposition could, at will, in effect transfer all exercises of discretion in interlocutory applications from a Judge in Chambers to a Court of Appeal.
