Legal principles
7 I summarised the principles relevant to a claim for legal professional privilege in Roberts-Smith v Fairfax Media Publications Pty Limited (No 23) [2021] FCA 1460; (2021) 157 ACSR 438 (Roberts-Smith (No 23)) at [37]-[46], expanded upon in respect of waiver of privilege in Roberts-Smith v Fairfax Media Publications Pty Limited (No 25) [2021] FCA 1558 at [18]-[26]. The following summary is taken in large part from those judgments.
8 As the respondent's claim for privilege is made in respect of the inspection of documents sought by a notice to produce, it is governed by the common law and not the Evidence Act 1995 (Cth): Esso Australia Resources Ltd v Federal Commissioner of Taxation [1999] HCA 67; (1999) 201 CLR 49 (Esso) at [16]-[17]; Australian Securities and Investments Commission v Australian Lending Centre Pty Ltd (No 2) [2011] FCA 1057; (2011) 283 ALR 299 at [6]-[9]; DBCT Management Pty Ltd v McConnell Dowell Constructors (Aust) Pty Ltd and Geosea Australia Pty Ltd Joint Venture [2021] FCA 512 (DBCT) at [74].
9 Legal professional privilege protects a person from being compelled to produce documents or give information which would reveal communications between a client and his or her lawyer, made for the dominant purpose of obtaining or providing legal advice, or the provision of legal services, including representation in pending or anticipated legal proceedings: Esso at [35], [61]; Daniels Corporation International Pty Ltd v Australian Competition and Consumer Commission [2002] HCA 49; (2002) 213 CLR 543 at [9]. The relevant time at which a claim for privilege is determined is the time it came into existence: Barnes v Commissioner of Taxation [2007] FCAFC 88; (2007) 242 ALR 601 at [5].
10 The dominant purpose is the "ruling, prevailing or most influential purpose": Federal Commissioner of Taxation v Spotless Services Ltd [1996] HCA 34; (1996) 186 CLR 404 at 416. It is a purpose that predominates over other purposes; the prevailing or paramount purpose: AWB Limited v Cole [2006] FCA 571; (2006) 152 FCR 382 (AWB) at [105]-[106]. The "dominant purpose" brings within the scope of the privilege a document brought into existence for the purpose of a client being provided with professional legal services notwithstanding that some ancillary or subsidiary use of the document was contemplated at the time: Esso at [58]. The purpose for which a document is brought into existence is a question of fact that must be determined objectively, having regard to the evidence, the nature of the document and the parties' submissions: AWB at [110].
11 An appropriate starting point when applying the dominant purpose test is to ask what was the intended use or uses of the document which accounted for it being brought into existence: Pratt Holdings Pty Ltd v Commissioner of Taxation [2004] FCAFC 122; (2004) 136 FCR 357 (Pratt 2004) at [35]. Attention is focused on the purpose (or purposes) of the person who created the document, or who, if not its author, had the authority to, and did, procure its creation: Pratt 2004 at [35]. Where the person who procured the creation of the document is not its author (such as a solicitor commissioning a report), the intention of that person, not the author, is relevant: Hartogen Energy Limited (in liq) v The Australian Gas Light Company [1992] FCA 484; (1992) 36 FCR 557 (Hartogen Energy) at 568-9. Although, as noted above, the existence of an ancillary purpose is not fatal to a privilege claim, if there are two purposes of equal weight, neither is dominant: The Commissioner of Taxation of the Commonwealth of Australia v Pratt Holdings Pty Ltd [2005] FCA 1247; (2005) 225 ALR 266 at [30(8)]; Re Southland Coal Pty Ltd (rec & mgrs apptd) (in liq) [2006] NSWSC 899; (2006) 203 FLR 1 at [14(h)].
12 The party claiming privilege bears the onus of proving the facts necessary to establish the relevant privilege, including that the communications or documents in question were made or created for the required dominant purpose: Grant v Downs [1976] HCA 63; (1976) 135 CLR 674 (Grant v Downs) at 689. The existence of privilege will not "necessarily or conclusively [be] established by resort to any verbal formula or ritual": Grant v Downs at 689. Nor will it necessarily be sufficient for a party merely to assert a claim for privilege or rely on an affidavit which asserts the purpose for which a document was brought into existence followed by a statement of the category of legal professional privilege to which the document is said to belong: National Crime Authority v S [1991] FCA 234; (1991) 29 FCR 203 at 211 (NCA v S); Kennedy v Wallace [2004] FCAFC 337; (2004) 142 FCR 185 at [13].
13 The concept of legal advice in the context of advice privilege is fairly broad. It goes beyond formal advice as to the law, and extends to professional advice as to what a party should prudently or sensibly do in a relevant legal context, but does not extend to advice that is purely factual or commercial: Balabel v Air India [1988] Ch 317 at 330; DSE (Holdings) Pty Ltd v InterTAN Inc [2003] FCA 1191; (2003) 135 FCR 151 at [45]; AWB at [100]; BWO19 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCAFC 181; (2020) 283 FCR 299 at [62]. Legal advice includes professional advice given by lawyers to a client as to what evidence and submissions should be placed before a commission of inquiry: AWB at [100]; Three Rivers District Council v Governor and Company of the Bank of England (No 6) [2004] UKHL 48; [2005] 1 AC 610 at [37]-[43], [113]-[120].
14 Litigation privilege attaches to confidential communications passing between a client and the client's lawyer or a third party, or the client's lawyer and a third party, where the communication was made for the dominant purpose of use in, or in relation to, existing or reasonably anticipated litigation: Mitsubishi Electric Australia Pty Ltd v Victorian WorkCover Authority [2002] VSCA 59; (2002) 4 VR 332 at [8]; Commissioner of Taxation v Pratt Holdings Pty Ltd [2003] FCA 6; (2003) 195 ALR 717 at [39]; AWB at [144]. The key difference between advice privilege and litigation privilege is that litigation privilege is not limited to communications whose dominant purpose is the giving or obtaining of legal advice: AWB at [145].
15 Given the focus of this application it is also necessary to refer to the principles relevant to waiver of privilege.
16 In Mann v Carnell [1999] HCA 66; (1999) 201 CLR 1 (Mann), the plurality explained the rationale and approach at [28]-[29] as follows (citations omitted):
[28] At common law, a person who would otherwise be entitled to the benefit of legal professional privilege may waive the privilege. It has been observed that "waiver" is a vague term, used in many senses, and that it often requires further definition according to the context. Legal professional privilege exists to protect the confidentiality of communications between lawyer and client. It is the client who is entitled to the benefit of such confidentiality, and who may relinquish that entitlement. It is inconsistency between the conduct of the client and maintenance of the confidentiality which effects a waiver of the privilege…
[29] Waiver may be express or implied. Disputes as to implied waiver usually arise from the need to decide whether particular conduct is inconsistent with the maintenance of the confidentiality which the privilege is intended to protect. When an affirmative answer is given to such a question, it is sometimes said that waiver is "imputed by operation of law". This means that the law recognises the inconsistency and determines its consequences, even though such consequences may not reflect the subjective intention of the party who has lost the privilege… 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.
17 When considering whether a waiver of privilege has occurred, each case must be assessed on its own facts: Commissioner of Taxation v Rio Tinto Limited [2006] FCAFC 86; (2006) 151 FCR 341 (Rio Tinto) at [45], [61]. As explained at [45]:
Where, as here, one party alleges that another has impliedly waived legal professional privilege, a court is bound to analyse the acts or omissions of the privilege holder that are said to be inconsistent with the maintenance of the privilege. In concluding that the Commissioner had waived the privilege in the eight contested documents, the docket judge in fact applied the "inconsistency" principle of Mann, as he was obliged to do: see Rio Tinto (2) at [20]. Plainly enough, the inquiry that it mandates focuses on the facts of the particular case. It follows that other cases in which implied waiver has been considered provide limited guidance unless they arise out of similar facts.
18 In DSE (Holdings) Pty Ltd v Intertan Inc [2003] FCA 384; (2003) 127 FCR 499, Allsop J (as his Honour then was) observed at [58] (emphasis in the original):
…the party entitled to the privilege makes an assertion (express or implied), or brings a case, which is either about the contents of the confidential communication or which necessarily lays open the confidential communication to scrutiny and, by such conduct, an inconsistency arises between the act and the maintenance of the confidence, informed partly by the forensic unfairness of allowing the claim to proceed without disclosure of the communication…
19 At [61] of Rio Tinto, the Full Court of the Federal Court observed:
Both before and after Mann, the governing principle required a fact-based inquiry as to whether, in effect, the privilege holder had directly or indirectly put the contents of an otherwise privileged communication in issue in litigation, either in making a claim or by way of defence…
20 Inconsistency may arise if the privilege holder makes assertions about its state of mind and there are likely to have been confidential communications which affected that state of mind: Council of the New South Wales Bar Association v Archer [2008] NSWCA 164; (2008) 72 NSWLR 236 at [48]. The question, however, is not whether a party has put their state of mind in issue but whether or not the privilege holder made an assertion as part of their case that lays open the privileged documents to scrutiny, with the consequence that an inconsistency arises between the making of the assertion and the maintenance of privilege: Rio Tinto at [65].
21 The Court has the power to examine documents in respect of which a privilege claim is made: Grant v Downs at 689. The essential purpose of inspecting the documents is "to determine whether, on its face, the nature and content of the document supports the claim for legal professional privilege": AWB Limited v Cole (No 5) [2006] FCA 1234; (2006) 155 FCR 30 at [44(12)]. "[I]n many instances the character of documents the subject of the claim will illuminate the purpose for which they were brought into existence": Grant v Downs at 689. A party is not entitled to insist on the court inspecting the documents, it being a matter for the discretion of the judge, who will only do so if there is good reason: Hancock v Rinehart (Privilege) [2016] NSWSC 12 at [31], citing Westminster Airways Ltd v Kuwait Oil Co Ltd [1951] 1 KB 134 at 146; District Council of Mallala v Livestock Markets Ltd [2006] SASC 80; (2006) 94 SASR 258 at [30]; Woollahra Municipal Council v Westpac Banking Corporation (1994) 33 NSWLR 529 at 542.
