Was there an implied or imputed waiver?
74 The first issue that arises for consideration is whether, as Ms McKenzie contends, by reason of Cash Converters' forensic deployment of the Couper QC Advices in the amended defence, they have waived all claims of privilege over communications that relate to the issue of the loan brokerage model, which was the topic upon which Mr Couper QC was instructed to opine and which Ms McKenzie alleges is the conduct at issue in the unconscionability claim. I accept Ms McKenzie's submission that that issue should be determined before any inspection of the documents in issue.
75 Ms McKenzie submitted that the relevant "transaction" to be considered by the Court is Cash Converters' formulation and use of the "loan brokerage model". She said that the evidence disclosed that this model was in use from August 2008 to 30 June 2013 and appeared to have begun to be formulated no later than July 2008. She further submitted that, similar to proceedings for professional negligence against a party's lawyer, a party cannot "pick and choose, disclosing such incidents of the relationship as strengthen [its] claim for damages and concealing them from forensic scrutiny such incidents as weaken it", referring to Paragon Finance Plc v Freshfields [1999] 1 WLR 1183; cited in Vic Hotel Pty Ltd v DC Payments Australasia Pty Ltd (2015) 321 ALR 191; [2015] VSCA 101 at [51].
76 Ms McKenzie contended that whether or not any alleged inconsistency has led to an issue waiver is inherently fact dependent. She submitted that the Couper QC Advices, which provide a positive opinion about the legality of the loan brokerage model at issue in this proceeding, are deployed by Cash Converters in the particulars to [35(e)], [43(f)] and [51(e)] of the amended defence and that they underpin Cash Converters' assertion that they acted in "good faith" within the meaning of s 12CC(1)(l) of the ASIC Act. Ms McKenzie submitted that the meaning and operation of the unconscionability provisions in the ASIC Act, particularly in the context of the statutory concept of "good faith", were recently explained by Allsop CJ, with whom Besanko and Middleton JJ agreed, in Paciocco v Australia and New Zealand Banking Group Ltd (2015) 236 FCR 199 (Paciocco) at [285], [288], [292] and [293]. Ms McKenzie further submitted that, against that background, Cash Converters sought to deploy the Couper QC Advices to secure a forensic advantage with respect to conclusions about their acting in "good faith" in implementing and using the loan brokerage model while claiming privilege over all other legal advice in relation to it.
77 Ms McKenzie contended that to selectively deploy legal advice in these circumstances is a classic act of inconsistency in the maintenance of the privilege in other communications on the same subject-matter and that it was unfair to deny her the opportunity to examine the whole of Cash Converters' legally privileged communications with respect to the loan brokerage model and its implementation over the relevant period of time in which the model was formulated and in use. She further contended that the waiver applies to all communications that relate, expressly or impliedly, to the legality of the loan brokerage model and that this was so whether or not the communication pre- or post-dated the Couper QC Advices.
78 The critical question for the Court in considering whether there has been an inconsistency of the kind referred to in Mann v Carnell is whether the content of an otherwise privileged communication has been put in issue in the litigation. As was recognised in DSE v Intertan, the question is whether the privilege holder has made an assertion about part of its case in the litigation "which is either about the contents of the confidential communication or which necessarily lays open the confidential communication to scrutiny" (original emphasis) such that "an inconsistency arises between the act and the maintenance of the confidence": at [58].
79 Ms McKenzie referred the Court to the following extracts from Paciocco where Allsop CJ considered the operation of the unconscionability provisions in the ASIC Act:
285 More specific guidance to the meaning and operation of s 12CB as a consumer provision is given by the matters set out in s 12CC … to which a court may have regard for the purposes of considering the question of unconscionable conduct. These matters assist in setting a framework for the values that lie behind the notion of the relevant conscience of the parties in trade or commerce identified in s 12CB. Those values and conceptions can be seen as: fairness and equality: see paras (a), (b), (d) to (k); a lack of understanding or ignorance of a party: para (c); the risk and worth of the bargain: paras (e) and (i); and good faith and fair dealing: para (l).
...
288 The usual content of the obligation of good faith that can be extracted from cases such as Renard Constructions, Hughes Bros Pty Ltd v Trustees of Roman Catholic Church (Archdiocese of Sydney) (1993) 31 NSWLR 91, Burger King Corporation v Hungry Jack's Pty Ltd (2001) 69 NSWLR 558, Alcatel Australia Ltd v Scarcella (1998) 44 NSWLR 349, and United Group Rail Services Ltd is an obligation to act honestly and with a fidelity to the bargain; an obligation not to act dishonestly and not to act to undermine the bargain entered or the substance of the contractual benefit bargained for; and an obligation to act reasonably and with fair dealing having regard to the interests of the parties (which will, inevitably, at times conflict) and to the provisions, aims and purposes of the contract, objectively ascertained.
…
292 Good faith does not import an equitable notion of the fiduciary that is rooted in loyalty to another in the service of her or his interests: Smith L, "Fiduciary Relationships: Ensuring the Loyal Exercise of Judgement on Behalf of Another" (2014) 130 LQR 608. Rather, it is rooted in honest and reasonable fair dealing: Macquarie International Health Clinic Pty Ltd v Sydney South West Area Health Service (2010) 15 BPR 28,563 at [12]-[13].
293 Trickery and sharp practice impede commerce by decreasing trust and increasing risk. Good faith and fair dealing promote commerce by supporting the central conception and basal foundation of commerce: a requisite degree of trust. Business people understand these things.
80 As submitted by Cash Converters, in Ms McKenzie's pleaded case that Cash Advance, Cash Stores and Bak Property each engaged in conduct that contravened s 12CB(1) of the ASIC Act in that, among other things, they did not act in good faith, she does not allege any dishonesty on the part of Cash Advance, Cash Stores or Bak Property. Given that, the issue that arises is whether Cash Advance, Cash Stores and Bak Property engaged in fair dealing or acted reasonably. That is the context in which the Couper QC Advices have been deployed.
81 More particularly, Cash Converters' amended defence puts in issue the Couper QC Advices in response to the allegation that each of Cash Advance, Cash Stores and Bak Property engaged in unconscionable conduct, contrary to s 12CB of the ASIC Act, and the allegation that they did not act in good faith. It follows, and Cash Converters accepts, that the amended defence "lays open" that advice to scrutiny. But, in my opinion, the waiver goes no further than the Couper QC Advices.
82 Ms McKenzie characterised the Couper QC Advices as a "positive opinion about the legality of the loan brokerage model at issue" in the proceeding. The nature of the Couper QC Advices is set out at [18] above. Mr Couper QC was asked to advise on two particular issues in relation to the loan brokerage model, namely, whether that model would cause the interest on loans to exceed the maximum permissible percentage rate under the QLD Regulation and whether it would breach any other provision of the QLD Code. To the extent that Mr Couper QC opined on the "legality" of the loan brokerage model, he did so in the context of the specific questions he was asked to address. It is difficult to see how the relevant transaction the subject of Mr Couper QC's advice could be the "loan brokerage model" more generally, as Ms McKenzie contended. That was not the subject of Mr Couper QC's advice, which was specifically focused on the two issues identified.
83 Contrary to Ms McKenzie's submission, it cannot be said that the disclosure of the Couper QC Advices amounted to a waiver of all other legal advice received by Cash Converters on the loan brokerage model. The particular communications that Cash Converters deploys in its amended defence are the advices given by Mr Couper QC. They have been put in issue and that advice, and the documents related to it, have been provided to Ms McKenzie. There has been no waiver of the nature and extent alleged by Ms McKenzie.
84 Ms McKenzie submitted that it was unfair to deny her the opportunity to examine the whole of Cash Converters' legally privileged communications with respect to the loan brokerage model and its implementation over the relevant period of time that the model was formulated and in use. However, as was observed in Arup, the principle that underpins implied waiver has undergone a process of judicial evolution and "fairness" was abandoned as the touchstone of implied waiver by the High Court in Mann v Carnell. The question for the Court is whether Cash Converters has directly or indirectly put the content of the otherwise privileged communication in issue or, put another way, whether there has been conduct that is inconsistent with the maintenance of the confidentiality in the communication that is subject to the claim for privilege. As the Full Court observed in Arup, the assessment of whether there has been an implied waiver will be informed by "considerations of forensic unfairness": at [29]. Here, the only otherwise privileged communications that have been put in issue are the Couper QC Advices. There is no inconsistency in Cash Converters maintaining privilege over other advices relating to the loan brokerage model over the relevant period, assuming that they exist.
85 The related issue that arises is the scope of the waiver that results from the voluntarily disclosed advices. This is particularly relevant to the documents in part A of the Privilege Challenges Table. Ms McKenzie accepts that those documents are privileged but contends that privilege has been waived because they are "source documents" with respect to the voluntarily disclosed advices from Mr Couper QC and Mr Bain QC.
86 Ms McKenzie referred to Attorney-General for the Northern Territory v Maurice (1986) 161 CLR 475 (Maurice), where the High Court stated that the test to determine the scope of any waiver of associated material is whether the material that the party has chosen to release from privilege represents the whole of the material relevant to the same issue or subject-matter: at 482 (per Gibbs CJ), 488 (per Mason and Brennan JJ) and 498-499 (per Dawson J).
87 In AWB (No 5) Young J considered in some detail the authorities concerning the scope of an imputed waiver. At [164] his Honour referred to the test set out by the High Court in Maurice, as was adopted by Ms McKenzie in her submissions, and set out the relevant extracts from the judgments of Gibbs CJ and Dawson J: at [165]-[166].
88 Relevantly, in Maurice at 481-482, Gibbs CJ observed that "where a document deals with a single subject-matter it would be unfair to allow a party to use part of the document and claim privilege as to the remainder". His Honour noted that, similarly, "where a party disclosed a document which contained part only of a memorandum which dealt with a single subject- matter, and then read the document to the judge in the course of opening the case, it was held that privilege was waived as to the whole memorandum", referring to Great Atlantic Insurance Co. v Home Insurance Co. [1981] 1 WLR 529. His Honour then continued:
The same test must be applied in deciding whether the use in legal proceedings of one document impliedly waives privilege in associated material. In Nea Karteria Maritime Co. Ltd v Atlantic & Great Lakes Steamship Corporation [No. 2] Mustill J. dealt with this question and suggested the following test:
"… where a party is deploying in court material which would otherwise be privileged, the opposite party and the court must have an opportunity of satisfying themselves that what the party has chosen to release from privilege represents the whole of the material relevant to the issue in question. To allow an individual item to be plucked out of context would be to risk injustice through its real weight or meaning being misunderstood."
(footnotes omitted)
89 In AWB (No 5) at [168] Young J observed that "[a] common application of associated material waiver relates to the case where an expert report has been prepared in reliance upon other documents". After referring to three Australian decisions which considered the status of material relied on by an expert and noting that, "[i]n England, the principle has been applied to documents which underpin or support expert evidence", Young J considered at [172]-[176] some of the English cases that he said illustrate the practical operation of the principle:
172 Several English cases illustrate the practical operation of the principle. In Nea Karteria Maritime Co Ltd v Atlantic & Great Lakes Steamship Corp (No 2) [1981] Com LR 138; [1981] Can. Com. R. 132, a lawyer gave evidence that he had conducted an interview on the basis of a list of questions prepared by the plaintiffs' lawyers. While privilege was waived with respect to the witnesses' answers, the plaintiffs sought to maintain privilege with respect to the list of questions: at 139-140.
173 Mustill J (as his Lordship then was) held at 140 that privilege over the list of questions had been waived by implication:
It seems to me that the written questions were, so to speak, part of the meeting. They were in a sense an agenda for the meeting. They formed the basis for one-half of the exchange between the lawyer and [the witness]. Evidence to that effect having been given by the lawyer, it seems to me that privilege must have been waived for those questions. And I think the interests of justice, which I believe to underlie the authorities on this part of the case, demand that the opposition and the court should have an opportunity to satisfy itself as to the accuracy of the evidence given to the lawyer as to the way in which he conducted the interview.
174 Mustill J drew a distinction at 140 between the instructions to the lawyer who carried out the questioning and the questions themselves; the instructions did not play a part in the meeting, did not form part of the body of events upon which the Court had to reach conclusions of fact, and were merely part of the prior history of those events.
175 In R v Secretary of State for Transport; Ex parte Factortame [1997] EWHC 445 (Admin); (1997) 9 Admin LR 591 at 599, Auld LJ made the following observations concerning the application of the test stated in Nea Karteria:
Much depends on whether the party making partial disclosure seeks to represent by so doing that the disclosed documents go to part or the whole of an "issue in question", the expression used by Mustill, J in the passage from his judgment in Nea Karteria that I have cited. The issue may be confined to what was said or done in a single transaction or it may be more complex than that and extend over a series of connected events or transactions. In each case the question for the court is whether the matters in issue and the document or documents in respect of which partial disclosure has been made are respectively severable so that the partially disclosed material clearly does not bear on matters in issue in respect of which material is withheld. The more confined the issue, for example as to the content of a single document or conversation, the more difficult it is likely to be to withhold, by severance, part of the document or other documents relevant to the document or conversation.
176 In Fulham Leisure Holdings Ltd v Nicholson Graham & Jones [2006] 2 All ER 599 at [11], Mann J suggested that it was helpful to approach the application of the test stated in Nea Karteria in three steps: first, identify the transaction in respect of which the disclosure has been made; secondly, ascertain from the nature of the disclosure or other evidence whether the transaction is wider than an advice given on a single occasion, if so, the whole of the wider transaction must be disclosed; and thirdly, the disclosure of the whole transaction may make it plain that further disclosure is necessary to avoid unfairness or misunderstanding of what has been disclosed. Mann J added at [18] that once the transaction has been identified the cases show that the whole of the material relevant to that transaction must be disclosed. It is not open to a waiving party to say that the transaction is simply what the party has chosen to disclose; the court will determine objectively what the real transaction is so that the scope of the waiver can be determined. His Lordship also said that the application of these principles will be very fact sensitive and will vary from case to case: at [19].
90 Young J was satisfied that AWB Ltd had deployed "the gist or substance of legal advice it had obtained" and that its actions in doing so were inconsistent with the maintenance of confidentiality in the advice and "the associated material which underpinned the legal advice": at [178]. Having come to that conclusion, his Honour was of the view that it was "necessary and appropriate" to make "specific findings as to the nature and consequences of each such disclosure". His Honour undertook that task at [180]-[197]. At [198]-[201] Young J then considered the scope of the waiver:
198 One question which remains to be dealt with is whether the scope of the waiver that must, in my view, be imputed to AWB is to be confined to any other legal advice that AWB obtained prior to the date of the relevant disclosures that addressed the same subject matters or issues as the advice that AWB voluntarily disclosed. In my opinion, the waiver is not so confined. It extends to the documents and information which were taken into account in formulating, or which otherwise underpinned or influenced, the legal advice that AWB has chosen to disclose.
…
200 According to the authorities discussed above, the limits of any waiver of associated material depend upon the nature of the advice that has been disclosed, what was represented by means of the disclosure, and the character of the transaction that gave rise to the disclosed legal advice. Regard must also be had to the way in which AWB's legal advice was described in the various disclosures. Essentially, by means of the disclosures, AWB was asserting that a detailed legal review had been undertaken, and that it had concluded that there was no evidence of any wrongdoing or other improper conduct by AWB in connection with its sale of wheat to Iraq under the OFF Programme. In my opinion, the nature and character of this disclosure is inconsistent with the maintenance of confidentiality in those documents which were taken into account by AWB's legal advisers in arriving at the advice they gave. To adapt the language used by McClellan CJ at Common Law in Thomas at [17] and [20], AWB's disclosures of its legal advice effect a waiver of privilege in the documents which were reviewed for the purposes of that advice or which influenced its content. Furthermore, AWB emphasised the breadth of its internal review in its various disclosures. In my view, AWB thereby waived privilege in documents which define the scope of the review or which reveal what investigations were in fact undertaken in the course of the review.
201 Much the same answer follows if one asks what was the legal exercise or transaction that gave rise to the disclosed legal advice: see Factortame at 598-599; and Fulham at [11] and [18]. Having regard to the form of the legal advice disclosed by AWB, the relevant legal exercise or transaction encompassed a review of original documents and witness interviews, as well as summaries, chronologies or other analytical documents prepared by the lawyers, with a view to determining whether there was any improper or wrongful conduct by AWB. Material of this kind underpinned or influenced the legal advice which AWB has chosen to disclose, and it is not severable from that advice.
91 The facts of the case before me are different to the facts before Young J in AWB (No 5). However, adopting his Honour's analysis at [200], the limits of the waiver depend on the nature of the Couper QC Advices, what was represented by their disclosure and the character of the transaction that gave rise to the Couper QC Advices. The Couper QC Advices addressed the two questions referred to at [82] above; Cash Converters deployed those advices in support of its defence that it acted in good faith; and the transaction that gave rise to the advices was a request for advice on those two questions arising out of the mediation described at [18] above. The transaction was not, as Ms McKenzie contended, the loan brokerage model used by Cash Converters over a five year period. The same result is reached adopting the analysis at [201] of AWB (No 5). At the time of this application Cash Converters had not filed evidence. There was nothing that could lead to a conclusion that the "transaction" or "legal exercise" was broader than the two issues considered in the Couper QC Advices.
92 Accordingly, the scope of the waiver in this case "extends to the documents and information which were taken into account in formulating, or which otherwise underpinned or influenced" the Couper QC Advices. It does not extend to "source documents" as defined by Ms McKenzie: see [94(1)] below.
93 I turn then to consider the documents in each part of the Privilege Challenges Table
