Parties' submissions on appeal
24 The parties agreed that in circumstances where ASIC was unable to see the whole of the report, and the appellant was unable to be too specific about what it said, lest it waive privilege over the whole of the document, there was, realistically speaking, little to be said by either side by way of substantive submission.
25 The appellant's written submissions included the following:
The appellant contends that the conclusions reached by the primary judge were erroneous, to the extent those conclusions went beyond accepting that there had been a waiver in respect of that part of the Report which addressed the CEO/CFO Involvement Allegation [that is, the allegation that the appellant's CEO and CFO had been involved in a scheme for the fake analysis of coal samples].
The only way in which this Court can form its own view as to the matter is to read and consider the Report, as the primary judge did.
It is accepted that the primary judge was correct to identify the existence of sections of the Report that addressed the CEO/CFO Involvement Allegation. The relevant issue number in the Report is issue 3(b) identified in the summary table on page 4 of the Report, and that issue was addressed in paragraphs 3.4.5 and 3.4.7 of the Report. The appellant accepts these parts of the Report were the subject matter of the disclosure, and privilege in relation to this part of the Report was waived as a result.
…
It is accepted that the CEO/CFO Involvement Allegation was a particular allegation within the Alleged Fake Analysis [that is, a scheme for the fake analysis of coal samples] contention that Mr Williams had made.
It is also accepted that the primary judge was correct to observe, at [J 82] … a connection, in a broad subject matter sense, between the various concerns identified using the number 3 (summarised in the table at page 4 of the Report) and the particular CEO/CFO Involvement Allegation. His Honour referred to those concerns collectively in the judgment as "concern 3".
What is challenged on this appeal is the correctness of the view held by the primary judge that is expressed in the last two sentences of [J 82] … and the conclusion based on that view that is set out in [J 83] …
In this regard, the disclosure by the appellant in the public announcements was as to a specific matter (CEO/CFO Involvement Allegation). The other parts of the Report to which the primary judge refers at [J 82] … do not address that particular allegation. That allegation, namely the CEO/CFO Involvement Allegation, is dealt with on its own in bespoke parts of the Report.
It is respectfully submitted that the primary judge erred in treating the various separate items identified using the number 3 as if they were one concern (referred to by his Honour as "concern 3"). Conceptually and legally they each stood on their own, albeit arising in the context of the same broad subject matter.
Applying the relevant test outlined above, it is submitted that there is not an inconsistency between the disclosure as to one subject matter (i.e. CEO/CFO involvement in a matter) and the maintenance of privilege over the Report's consideration of whether the matter occurred.
That correctness of that contention is revealed by an appreciation of the fact that whether the matter in question occurred or not is, in fact, irrelevant to whether or not the CEO or CFO were involved - that is, even if one could assume for the sake of this argument that the matter occurred or there was some evidence or finding as to that topic, it does not begin to follow that the CEO or CFO were in any way involved.
26 The appellant also made an alternative proposal about redactions.
27 The appellant contended that if we did not accept its contentions, and agreed with the primary judge that the necessary inconsistency existed, we should nonetheless find that there was only waiver in respect of the parts of the PwC report identified in an alternatively masked confidential version of it provided to the court and marked "B". That version contains significantly fewer redactions, which the appellant said concern matters that are sufficiently removed from the subject matter of the letter to shareholders and the relevant ASX announcement, such that no inconsistency between the maintenance of the privilege and the appellant's conduct arises.
28 ASIC submitted that the appellant must establish "an error of principle or a material error of fact, or, if no specific error can be identified, [it must demonstrate] that the decision is unreasonable or plainly unjust", citing UBS AG v Tyne (2018) 265 CLR 77 at 105 [74] (Gageler J); and House v The King (1936) 55 CLR 499 at 505 (Dixon, Evatt and McTiernan JJ). ASIC contended that in answering question 3, the judge made "evaluative conclusions in respect of which the applicable legal criteria permitted of some latitude of choice or margin of appreciation such as to admit of a range of legally permissible outcomes", and that the principles in House v The King thus apply, citing Minister for Immigration and Border Protection v SZVFW (2018) 264 CLR 541 at 561 [44] (Gageler J). See also Ghosh v NineMSN Pty Ltd (2015) 90 NSWLR 595 at 601 [37] (Macfarlan JA) (evaluative decisions of a subjective nature, regarding an issue upon which minds may differ, are not strictly discretionary decisions but appellate intervention nevertheless depends upon satisfaction of the same principles in House v The King).
29 We do not accept that contention. In deciding that although privilege over only part of the report had been waived, partial disclosure of the contents of the report by the disclosure of the subject matter of concern 3(b) led "ineluctably" to waiver of legal professional privilege in respect of the whole report, the learned judge was not exercising a discretion of the type contemplated in the well-known passage from House v The King (1936) 55 CLR 499 at 504-505, viz:
The manner in which an appeal against an exercise of discretion should be determined is governed by established principles. It is not enough that the judges composing the appellate court consider that, if they had been in the position of the primary judge, they would have taken a different course. It must appear that some error has been made in exercising the discretion. If the judge acts upon a wrong principle, if he allows extraneous or irrelevant matters to guide or affect him, if he mistakes the facts, if he does not take into account some material consideration, then his determination should be reviewed and the appellate court may exercise its own discretion in substitution for his if it has the materials for doing so. It may not appear how the primary judge has reached the result embodied in his order, but, if upon the facts it is unreasonable or plainly unjust, the appellate court may infer that in some way there has been a failure properly to exercise the discretion which the law reposes in the court of first instance. In such a case, although the nature of the error may not be discoverable, the exercise of the discretion is reviewed on the ground that a substantial wrong has in fact occurred.
30 Although the point was not fully argued, it seems to us that where on appeal a party challenges a decision of a trial judge contending that, by its limited disclosure of legal advice contained in a report (or other document), it has waived privilege over the whole of that report (or document), the correctness or otherwise of that decision is a question susceptible of only one answer. Compare Minister for Immigration and Border Protection v SZVFW (2018) 264 CLR 541 at 552 [18] (Kiefel CJ), 565-566 [55]-[56] (Gageler J), 574-575 [85]-[87] and 580 [117] (Nettle and Gordon JJ), and 593-594 [154]-[155] (Edelman J). It follows that, in our view, this court is in as good a position as the primary judge to determine the correct answer to question 3, and the principle in House v The King has no application to the issue on appeal here.
31 Otherwise, as ASIC said in its written submissions, it was "unable properly to engage with whether the redacted parts of the PwC Report deal with distinct or different subject-matters and to advance submissions in respect of that question".
