Overview of legal advice privilege
9 The present dispute, which is concerned with pre-trial disclosure and inspection rather than the adducing of evidence, is to be determined according to the common law rather than the Evidence Act 1995 (Cth): Esso Australia Resources Limited v Commissioner of Taxation (1999) 201 CLR 49 at [17]-[28] (per Gleeson CJ, Gaudron and Gummow JJ); at [64] (per McHugh J).
10 Legal advice privilege "may be availed of by a person to resist the giving of information or the production of documents which would reveal communications between a client and his or her lawyer made for the dominant purpose of giving or obtaining legal advice": Daniels Corporation International Pty Ltd v Australian Competition and Consumer Commission (2002) 213 CLR 543 at [9], per Gleeson CJ, Gaudron, Gummow and Hayne JJ.
11 The "dominant" purpose is a prevailing or paramount purpose or one which predominates over other purposes: AWB Ltd v Cole (2006) 152 FCR 382 at [105], per Young J; Archer Capital 4A Pty Ltd v Sage Group Plc (No 2) (2013) 306 ALR 384 at [11], per Wigney J. The purpose for which a communication is made is a question of fact to be determined objectively from the nature of the relevant communication, the content of the communication, the relevant commercial context and the relationships between the parties: Commissioner of Taxation v Pratt Holdings Pty Ltd (2005) 225 ALR 266 at [30], per Kenny J; AWB at [110]. Notwithstanding that the purpose must be determined objectively, evidence of subjective purpose is relevant and although not necessarily conclusive, can be decisive: Esso at [172], per Callinan J; AWB Ltd v Cole (No 5) (2006) 155 FCR 30 (AWB No 5) at [44(2)], per Young J; Archer at [11]; Asahi Holdings (Australia) Pty Ltd v Pacific Equity Partners Pty Limited (No 4) [2014] FCA 796 at [32]. Of course, mere assertion that disclosure may tend to reveal privileged material is inadequate: DSE (Holdings) Pty Ltd v InterTAN Inc (2003) 135 FCR 151 at [29].
12 The relevant time for ascertaining purpose is when the communication was made. If the communication or a component of it was the provision of a copy document, it is the purpose of the creation of the copy which is relevant, ascertained at the time the copy was created: Asahi at [30].
13 Privilege extends to documents from which the nature and content of a legally privileged communication might be inferred: Commissioner of Australian Federal Police v Propend Finance Pty Ltd (1997) 188 CLR 501 at 569, per Gummow J; Commissioner of Taxation v Pratt Holdings Pty Ltd (2004) 136 FCR 357 at [20] (per Finn J), [88] (per Stone J); Lakatoi v Walker [1999] NSWSC 156 at [15], per Rolfe J. Examples include: communications between various legal advisers of the client, draft pleadings, draft correspondence with the client, documents with a lawyer's handwritten annotations and bills of costs. Privilege extends to internal documents or parts of documents of the client, or of the lawyer, reproducing or otherwise revealing communications which would be covered by privilege: AWB No 5 at [46].
14 Privilege extends to a copy of a non-privileged document where the dominant purpose for bringing the copy into existence was to obtain legal advice: Propend, as modified by the dominant purpose test in Esso. Although this principle applies to documents, it should be recognised that the privilege protects communications of which the copy documents might form a component or from which the nature and content of a privileged communication might be inferred. If a client makes a copy of a non-privileged communication or document and sends it to a lawyer without a dominant purpose of obtaining legal advice (or for confidential use in litigation), the copy would not be privileged. The Propend principle also applies to a document copied by a lawyer for the dominant purpose of giving legal advice.
15 The concept of "legal advice" is not to be narrowly construed as formal advice as to the law; it extends to advising about what should prudently be done in a relevant legal context but does not extend to purely factual or commercial advice: DSE at [45]; Archer at [12]. Where a lawyer has been retained for the purposes of providing legal advice in relation to a particular transaction, communications between the lawyer and client relating to the transaction will prima facie be privileged, notwithstanding they do not contain advice on matters of law; it is usually enough that they are directly related to the performance by the lawyer of his or her professional duty as legal adviser to the client: AWB No 5 at [47]; DSE at [51]-[52].
16 Particularly in the context of protracted or complex transactions, where information is passed between lawyer and client as part of a continuum aimed at keeping both informed so that advice may be sought and given as required, privilege may attach: Balabel v Air India [1988] Ch 317 at 330; Pratt at [87], per Stone J; DSE at [38].
17 Courts may examine the documents the subject of the privilege dispute in order to determine whether the nature and content of the documents support the privilege claim by throwing light on the purpose for which they were brought into existence: Grant v Downs (1976) 135 CLR 674 at 689, per Stephen, Mason and Murphy JJ; AWB No 5 at [44(12)]; Asahi at [36].
18 The onus of establishing that privilege applies such that disclosure may be resisted is on the person asserting the privilege: Grant at 689.
19 A number of the sample documents comprise a print out of an email chain. Where the relevant document comprises an email chain, I refer to the most recent in time email as the "lead email". It is the lead email which has been discovered, and which comprises the principal communication. The dominant purpose of making that lead communication is important to the analysis of the treatment of other emails in the chain. Often, the lead email forwards, or replies to, an email chain. Whilst the analysis turns each time on the particular document (a print out of the communication being the lead email and any chain), it is perhaps useful to make the following observations (disregarding for present purposes any question of waiver of privilege):
(1) If the communication being the lead email was not made for the dominant purpose of obtaining or giving legal advice, then it may nevertheless be appropriate to redact parts of the lead email or subsequent emails in the chain, or attachments to the lead email, if the content or nature of a privileged communication might be inferred from the document if it were left unredacted - see: paragraph [13] above.
(2) If the dominant purpose of the communication being the lead email was the giving of legal advice by a retained lawyer, then it may be that the email chain will be privileged because the subsequent emails in the chain are to be regarded, in effect, as copies of documents furnished by the lawyer with the advice being the lead email. The lead email is a communication of legal advice, with the subsequent emails in the chain being components of that communication (in effect, copies of documents) provided by the lawyer for the dominant purpose of providing the legal advice (and perhaps also constituting copies of communications to the lawyer for the purpose of obtaining the advice). If the dominant purpose of the lawyer notionally making the copy of the email chain beneath the lead email was to provide the email chain to the client as part of the communication of legal advice, that email chain is privileged.
(3) If the dominant purpose of the communication being the lead email was the obtaining of legal advice from a retained lawyer, then the email chain may also be privileged because that email chain is, in effect, a copy of communications provided to the lawyer for the dominant purpose of obtaining legal advice. The forwarding of a chain of emails might constitute or be treated as "material prepared for submission to the legal adviser" or "components" of the privileged communication being the lead email: Propend at 571. So far as concerns the email chain forwarded with the lead email, the inquiry centres on the dominant purpose of the client in making what is, in effect, a copy of the email chain. It is at the point in time when the email chain is notionally copied (when it is notionally copied by forwarding or replying) that the question of dominant purpose must be analysed - see: paragraph [12] above. At that time, the whole chain is generally notionally copied (by forwarding or replying) as a component of the lead email, even though it may be that only particular emails in the chain were regarded as relevant or significant to the obtaining of advice. The dominant purpose of making the copy of the chain is often, if not generally, to put particular emails in the chain for submission to the lawyer. I did not exclude the possibility that it is appropriate in a particular case to treat the forwarding of an email chain as an act of copying each email in the chain individually, rather than a single act of copying the chain, such that one would need to analyse the dominant purpose of each act of copying. However, the circumstances were not such in the present case for such an approach to be taken.
20 The third category above was considered in Kamasaee v Commonwealth (No 2) [2016] VSC 404 at [43]-[47]. Macaulay J held that 'forwarding' an antecedent chain of emails to a lawyer to obtain advice amounted to making a copy of the email chain for the dominant purpose of providing it to the lawyer for advice. It did not matter that the earlier emails themselves were non-privileged communications. See also Desane Properties Pty Ltd v New South Wales [2018] NSWSC 173 at [178]-[181], per Robb J; Cargill Australia Ltd v Viterra Malt Pty Ltd (No 8) [2018] VSC 193 at [33]-[36], per Macaulay J.
