3 There was agreement between the parties that the following principles apply in relation to a claim for privilege and waiver (I take this exposition from the written submissions of Mr Speakman and Mr Moujalli):
(a) Section 118 protects confidential communications and the contents of confidential documents made or prepared for the dominant purpose of a lawyer providing legal advice to a client. In this context, "the concept of legal advice is fairly wide": AWB Ltd v Cole (2006) 155 FCR 30 at [44(7)] per Young J. In General Manager, WorkCover Authority of NSW v Law Society of NSW [2006] NSWCA 84 at [77]-[78], McColl JA quoted, with apparent approval, the observation of Taylor LJ in Balabel v Air India [1988] Ch 317 at 330, that "legal advice is not confined to telling the client the law; it must include advice as to what should prudently and sensibly be done in the relevant legal context". To qualify as legal advice, the lawyer must make the communication in the professional capacity of a lawyer: at [90].
(b) The dominant purpose of a communication must be determined objectively, having regard to the evidence, the nature of the document and the parties' submissions: Grant v Downs (1976) 135 CLR 674 at 677 per Barwick CJ, 689 per Stephen, Mason and Murphy JJ; Commissioner of Taxation (Cth) v Pratt Holdings Pty Ltd (2006) 225 ALR 266 at [30(3)] per Kenny J; Southland at [14(h)].
(c) Where the relevant communication is recorded in a document, the court has power to examine the document for itself to determine a contested privilege claim: s 133 of the Act; Grant v Downs (1976) 135 CLR 674 at 677 per Barwick CJ, 689 per Stephen, Mason and Murphy JJ. The purpose for which a communication is made is often clear and obvious from an inspection of the relevant document, as indicated in the approach taken by Austin J in Southland. Thus as put in Southland at [37]:
"… it will often be unnecessary for [a] deponent to reveal the source for his assertion that the document is a subsequent communication revealing the contents of confidential legal advice, if in the circumstances it is obvious that the source is perusal of the document itself".
d) Section 118 of the Act prevents not only disclosure of a document prepared for a privileged purpose, but any evidence which would result in disclosure of a privileged "confidential communication". As Austin J said in Southland at [14(e)]:
"The question is whether what is disclosed by adducing the evidence explicitly reveals the confidential communication or the contents of the confidential document, or supports an inference of fact as to the content of the confidential communication or document, which has a definite and reasonable foundation".
This is consistent with the common law, under which "privilege extends to any document prepared by a lawyer or client from which might be inferred the nature of the advice sought or given": Commissioner of Australian Federal Police v Propend Finance Pty Ltd (1997) 188 CLR 501 at 569 per Gummow J. This is simply a corollary of the proposition that privilege protects communications and not documents per se: Propend , Dawson J at 515, Toohey J at 525, Gaudron J at 543, McHugh J at 552 and Gummow J at 569. It therefore attaches not only to documents which constitute a privileged communication but any documents from which a privileged communication might be disclosed or inferred.
(e) Severance (or the withholding of part of a document) is permitted by the doctrine of privilege where only part of the document would disclose, or allow an inference to be drawn as to the nature of, a privileged communication: Waterford v Commonwealth (1987) 163 CLR 54 at 66 per Mason and Wilson JJ, 85 per Deane J and 103 per Dawson J; Grofam Pty Ltd v Australia New Zealand Banking Group Ltd (1993) 43 FCR 408.
(f) The party claiming privilege bears the onus of establishing the basis of the claim. In Grant v Downs , Stephen, Mason and Murphy JJ said at 689:
"It is for the party claiming privilege to show that the documents for which the claim is made are privileged. He may succeed in achieving this objective by pointing to the nature of the documents or by evidence describing the circumstances in which they were brought into existence".
See also Southland at [14(c)]; Commissioner of Taxation v Pratt Holdings [2005] FCA 1247at [30(1)].
(g) However the facts need only be established on the balance of probabilities: s 142 of the Act; Southland at [14(c)].
(h) The party claiming privilege does not bear the onus of excluding waiver of the privilege. Where it is alleged that privilege has been waived, the party alleging waiver carries the onus of establishing waiver: eg Nine Films & Television Pty Ltd v Ninox Television Ltd (2005) 65 IPR 442 at [21], Rich v Harrington [2007] FCA 1987 at [8]. As Campbell J said in Re Doran Constructions Pty Ltd (in liq) (2002) 194 ALR 101 at [117]:
"It is the party who asserts that there has been a waiver who bears the onus of satisfying the court about each of the elements in s 122(2)".
(i) Issues as to the implied waiver of privilege are to be determined in accordance with sub-section 122(2) of the Act. The Evidence Act provisions are to be interpreted in accordance with the common law approach to implied waiver: Ashfield Municipal Council v RTA [2004] NSWSC 917 at [14] per Barrett J. It is "settled" for New South Wales trial judges ( French v Polar Technologies International Pty Ltd [2006] NSWSC 1260 at [13]) and "firmly established" ( New Cap Reinsurance Corporation Ltd (In Liq) v Renaissance Reinsurance Ltd [2007] NSWSC 258 at [44]) by the decision of the Court of Appeal in Chen v City Convenience Leasing Pty Ltd [2005] NSWCA 297 that principles of implied waiver at common law are largely translated to "consent" under section 122 of the Evidence Act.
(j) As to those common law principles, in Mann v Carnell (1999) 201 CLR 1 at [29], Gleeson CJ, Gaudron, Gummow and Callinan JJ stated:
"What brings about the waiver is the inconsistency, which the courts, where necessary informed by considerations of fairness, perceive, between the conduct of the client and maintenance of the confidentiality; not some overriding principle of fairness operating at large".
It was noted that whilst some of the decisions deal with the general law and care needs to be taken in considering the Evidence Act, the courts continue to be guided by those earlier decisions in determining privilege under the Evidence Act: Re Southland; Ashfield Municipal Council v RTA [2004] NSWSC 917.
