Relevant principles
31 Legal professional privilege extends to several categories of communication, including:
(1) Communications between a party and the party's professional legal adviser, if confidential and made to or by the adviser in his or her professional capacity and with a view to obtaining or giving legal advice or assistance, even if the communications are made through agents of the party and the solicitor or either of them.
(2) Documents prepared with a view to being used in the way described in category (1) above, although not in fact so used.
(3) Communications between the various legal advisers of the client, such as between the solicitor and the solicitor's partner or agent, with a view to the client obtaining legal advice or assistance.
(4) Notes, memoranda, minutes or other documents made by the client or officers of the client or the legal adviser of the client of communications which are themselves privileged, or contain a record of those communications, or relate to information sought by the client's legal adviser to enable the adviser to advise the client or to conduct litigation on the client's behalf.
(5) Communications and documents passing between the party's solicitor and a third party if they are made or prepared when litigation is anticipated or commenced, for the purposes of the litigation, with a view to obtaining advice about the litigation or evidence to be used in it or information which may result in the obtaining of such evidence.
(6) Communications passing between the party and a third person (who is not the agent of the solicitor to receive the communication from the party) if they are made with reference to litigation either anticipated or commenced, and at the request or suggestion of the party's solicitor; or, even without any such request or suggestion, they are made for the purpose of being put before the solicitor with the object of obtaining his or her advice or enabling him or her to prosecute or defend an action.
(7) Knowledge, information or belief of the client derived from privileged communications made to the client by the client's solicitor or agent.
See Trade Practices Commission v Sterling (1979) 36 FLR 244 ("Sterling") at 245-246 and the authorities referred to there.
32 Most of the documents in question in the present case are said to fall within the first of these categories. Two -- the communications to which objection was taken in documents 59 and 62 -- are said to fall within the fourth category.
33 A useful summary of the general principles governing legal advice privilege appears in the judgment of Young J in AWB Ltd v Cole (No 5) (2006) 155 FCR 30 at [44]. I have already dealt with the questions of onus of proof and the power of the Court to examine the documents. It is sufficient for present purposes to note the following matters.
34 The first is the breadth of the term "legal advice". It extends beyond formal advice on the law to strategic advice in a relevant legal context or, as Young J put it in AWB Ltd & Cole at [44], "to professional advice as to what a party should prudently or sensibly do in the relevant legal context", picking up what Taylor LJ said in Balabel v Air India [1988] Ch 317 ("Balabel") at 330. It does not, however, extend to advice of a purely commercial or public relations character.
35 Secondly, the question of purpose is to be determined objectively. Evidence as to purpose from the maker of the document or the person who authorised or sought it may be received but is not conclusive and the existence of privilege is not established simply by the use of a verbal formula: Grant v Downs at 689 (Stephen, Mason and Murphy JJ).
36 Thirdly, in a communication between solicitor and client, it is likely that the relevant purpose is that of the client and, in a communication between a lawyer and a third party, that of the lawyer: Heydon JD, Cross on Evidence (10th ed, LexisNexis Butterworths, 2013), [25240].
37 Fourthly, legal professional privilege may apply to communications to and from in-house lawyers: Attorney-General for the Northern Territory v Kearney (1985) 158 CLR 510 at 530-521, Waterford v Commonwealth (1987) 163 CLR 54 ("Waterford") at 61-62, 79-82, 95. Thus, the circumstance that these are lawyers either employed by the Department of Defence or engaged in the service of the armed services providing legal advice to others in the service does not deprive the communications of the protection of the privilege, provided there is "a professional relationship which [nonetheless] secures to the advice an independent character" (Waterford at 62 (per Mason and Wilson JJ).
38 As Dawson J observed in Waterford at 95-96:
[L]egal professional privilege may attach to communications passing between a salaried legal adviser and his employer, provided that the legal adviser is consulted in a professional capacity in relation to a professional matter and the communications are made in confidence and arise from the relationship of lawyer and client. For this reason the legal adviser must be qualified to practise law and, it seems, subject to the duty to observe professional standards and the liability to professional discipline.
39 Historically, the relationship between members of the Defence services and the Commonwealth has not been one of employer and employee: see Millar v Bornholt at [70] ff. See also Defence (Personnel) Regulations 2002 (Cth), reg 117, which relevantly provides that no civil contract of any kind is created with the Crown or the Commonwealth as a result of the appointment of an officer or the enlistment of an enlisted member. Presumably, this explains why the applicant is seeking relief in respect of his termination under the ADJR Act.
40 Nevertheless, the evidence given by MAJ Guilfoyle establishes that the legal advice the subject of the communications in dispute in the present case was provided by persons qualified to practise law, who were in a fiduciary relationship with the officers who consulted them, subject to the duty to observe professional standards and liable to professional discipline.
41 Fifthly, where there are communications between a client and their lawyers, whether external or in-house, conducted on a professional basis, it may be appropriate to assume that legitimate legal advice was sought absent any indication to the contrary: Kennedy v Wallace (2004) 208 ALR 424; [2004] FCA 332 at [65] (Gyles J), affirmed on appeal: 142 FCR 185 at [23]-[27]. Gyles J said that "such an assumption rests upon judicial notice of, and judicial authority to enforce, the legal and ethical responsibilities of Australian legal practitioners and upon a common understanding as to the body of Australian law which must be complied with" (the Full Court did not express a concluded view on this point). It is unnecessary in this case to refer to the criticisms of the limitation of the principle to Australian lawyers made by Allsop J (as the Chief Justice then was) in Kennedy v Wallace 142 FCR 185 at [198]ff with which Black CJ and Emmett J agreed at [62].
42 Similarly, in Dalleagles Pty Ltd v Australian Securities Commission (1991) 4 WAR 325 at 333, followed by Allsop J in DSE (Holdings) at [71] Anderson J said:
In my opinion, discourse between solicitor and client with reference to the transactions covered by those instructions, that is professional discourse in a professional capacity, should be regarded as prima facie for the purpose of giving and receiving advice. This would apply to any communication that is on its face a communication of a professional nature from the solicitor to the client or his agent touching the subject matter of the solicitor's engagement and any communication from the client to the solicitor in connection with that engagement.
