for the dominant purpose of the lawyer, or one or more of the lawyers, providing legal advice to the client.
23 Section 118 is in Pt 3.10 and is concerned with the admissibility of evidence in court proceedings: Esso Australia Resources Ltd v Commissioner of Taxation of the Commonwealth of Australia [1999] HCA 67; (1999) 201 CLR 49 at 55. It has no application to a request by STC under s 68(2) of the SA Act. The Court is not being asked to determine in these proceedings whether a particular communication or document made or prepared is subject to privilege and that, therefore, evidence regarding its contents may not be adduced in the proceedings. What is being sought are orders that the determination of STC made on 2 December 2009 be set aside and the appellant's application be remitted to STC for determination on its merits, essentially on the grounds that the appellant is not obliged to comply with s 68(1) of the SA Act because the communication or document (if it exists) is privileged.
24 Section 131A of the Evidence Act extends the application of the provisions of Pt 3.10 (other than the provisions of ss 123 and 128) to some ancillary processes and pre-trial stages of proceedings, but a request under s 68(1) of the SA Act does not constitute an ancillary proceeding.
25 However, the circumstances in which legal professional privilege may apply are not limited to the adducing of evidence (Mann v Carnell [1999] HCA 66; (1999) 201 CLR 1) and the application of the privilege is not confined to judicial or quasi-judicial proceedings (Baker v Campbell [1983] HCA 39; (1983) 153 CLR 52). In Esso it was said that: '[T]he ambit of the common law doctrine of legal professional privilege in Australia exceeds that of the relevant provisions of the Evidence Act' (at 55 per Gleeson CJ, Gaudron and Gummow JJ).
26 In Attorney-General for the Northern Territory v Maurice [1986] HCA 80; (1986) 161 CLR 475 at 490, Deane J stated:
It is a substantive general principle of the common law and not a mere rule of evidence that, subject to defined qualifications and exceptions, a person is entitled to preserve the confidentiality of confidential statements and other materials which have been made or brought into existence for the sole purpose of his or her seeking or being furnished with legal advice by a practising lawyer or for the sole purpose of preparing for existing or contemplated judicial or quasi-judicial proceedings (see, generally, Baker v. Campbell (1983) 153 CLR 52). That general principle is of great importance to the protection and preservation of the rights, dignity and freedom of the ordinary citizen under the law and to the administration of justice and law in that it advances and safeguards the availability of full and unreserved communication between the citizen and his or her lawyer and in that it is a precondition of the informed and competent representation of the interests of the ordinary person before the courts and tribunals of the land. Its efficacy as a bulwark against tyranny and oppression depends upon the confidence of the community that it will in fact be enforced. That being so, it is not to be sacrificed even to promote the search for justice or truth in the individual case or matter and extends to protect the citizen from compulsory disclosure of protected communications or materials to any court or to any tribunal or person with authority to require the giving of information or the production of documents or other materials …
27 The question of privilege was the subject of proceedings in the High Court in The Daniels Corporation International Pty Ltd v Australian Competition and Consumer Commission [2002] HCA 49; (2002) 213 CLR 543. The proceedings involved the application of s 155 of the Trade Practices Act 1974 (Cth). The Australian Competition and Consumer Commission ('ACCC') has wide information-gathering powers under s 155 to enter premises to inspect and copy material or issue notices requesting materials. For example, s 155(1) provided:
[I]f the Commission, the Chairperson or the Deputy Chairperson has reason to believe that a person is capable of furnishing information, producing documents or giving evidence relating to a matter that constitutes, or may constitute, a contravention of this Act, or is relevant to a designated telecommunications matter (as defined by subsection (9)) or is relevant to the making of a decision by the Commission under subsection 93(3) or (3A), a member of the Commission may, by notice in writing served on that person, require that person:
(a) to furnish to the Commission, by writing signed by that person or, in the case of a body corporate, by a competent officer of the body corporate, within the time and in the manner specified in the notice, any such information;
(b) to produce to the Commission, or to a person specified in the notice acting on its behalf, in accordance with the notice, any such documents; or
(c) to appear before the Commission at a time and place specified in the notice to give any such evidence, either orally or in writing, and produce any such documents.
Failure to comply attracted a fine or imprisonment.
28 The ACCC issued s 155 notices to Daniels Corporation and its legal advisers, requiring the production of privileged communications. Daniels Corporation resisted and the ACCC commenced proceedings seeking production of the privileged material. It was held by the Full Federal Court that the ACCC had the power to obtain privileged communications. On appeal, the High Court determined that the ACCC could not use its information-gathering powers to compel the production of privileged communications.
29 At 552-553 the High Court stated in relation to legal professional privilege (citations omitted):
It is now settled that legal professional privilege is a rule of substantive law which 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 or the provision of legal services, including representation in legal proceedings. It may here be noted that the "dominant purpose" test for legal professional privilege was recently adopted by this Court in Esso Australia Resources Ltd v Federal Commissioner of Taxation in place of the "sole purpose" test which had been applied following the decision in Grant v Downs.
