Scope of standard discovery in the present case
14 The plaintiffs sought orders compelling Grant Thornton to discover documents located by a reasonable search that are directly relevant to the issues in the case, comprising documents upon which Grant Thornton intend to rely, are adverse to Grant Thornton's case, or adverse to the plaintiffs' case. It is central to the dispute that the plaintiffs sought to require Grant Thornton to discover the entirety of its audit or review files, working papers and correspondence including any such documents that concerned the September 2006 Prospectus.
15 The plaintiffs relied on the advice of an (at this stage unnamed) audit and accounting expert ("the audit expert"). The audit expert advised the solicitors for the plaintiffs that he or she needed to see:
(a) time records so that he or she could see how long the various members of the teams spent on different aspects of the audit or review. This was to assist the expert to determine whether the manner in which the work was done and delegated was that which would have been conducted by a reasonably competent audit firm;
(b) correspondence between Grant Thornton and Arasor and between Grant Thornton and auditors of subsidiary companies. This was to enable the audit expert to assess whether standards relating to the use of work of other auditors had been complied with and whether there were matters in correspondence which a reasonably competent auditor should have taken account of in planning and conducting the audit or review; and
(c) documents prepared or received in the course of the audit or review such as minutes, file notes, documents in relation to communications with Arasor, working papers, including audit or review programs, audit or review planning documents, descriptions of systems and processes, analyses and testing, issues memoranda, summaries of significant matters, contracts, agreements and checklists concerning significant matters, reviews of audit or review work performed by auditors of subsidiary entities and copies of financial statements, both final and those upon which review work had been conducted or noted.
16 Importantly, the audit expert advised that he or she needed all of Grant Thornton's auditing files because they:
…enable me to see how the audits or reviews were planned or conducted; how the findings were assessed; and how findings were communicated to shareholders and directors or management… [a]ll the parts of an audit or review are interrelated so that a matter dealt with in one part of the working papers may [be] relevant and of significance to another part of the audit or review. For me to assess the work done, it is important that I am able to see and evaluate the whole of the audit or review…
On this basis the plaintiffs sought the entirety of Grant Thornton's audit or review files, including working papers, correspondence and time records.
17 On the assumption that an order for standard discovery would be made, Grant Thornton contended that it should not be obliged to discover the entirety of its files. Amongst other things it contended that:
(a) the allegations regarding its provision of negative assurances at paragraphs 45 and 46 of the ACSOC are not the source of great controversy;
(b) there is no claim that the making of the negative assurances was misleading; and
(c) the only other part of the pleading which links Grant Thornton to the September 2006 Prospectus is the allegation at paragraph 68 that the statements and representations in the prospectus were repeated in the March 2007 Prospectus, and that they were misleading statements or representations as at that date.
While those matters can be accepted they do not go far.
18 Grant Thornton argued that there is no basis for concluding that the documents regarding the September 2006 Prospectus described at paragraphs 11-16 of the Second Schedule to Ms Banton's affidavit are directly relevant to the issues raised by the pleadings or will facilitate the just resolution of the proceeding as quickly, inexpensively and efficiently as possible. It contended that documents in connection with the September 2006 Prospectus cannot be directly relevant to any disputed issue between the plaintiffs and Grant Thornton, and that the application is merely a fishing expedition and oppressive.
19 I do not accept these contentions. In my view Grant Thornton should discover all of its audit or review files regarding Arasor including in relation to the September 2006 Prospectus, including working papers, correspondence and time records.
20 I say this, first, because the class action makes claims on behalf of all persons who acquired an interest in Arasor shares over a 19 month period on the ASX and in two capital raisings. I was not provided with any assessment of the quantum of damages claimed in the proceeding, but I approach the scope of discovery on the basis that the proceeding claims damages of tens of millions of dollars on behalf of some thousands of class members.
21 Second, I accept the plaintiffs' submission that there is a substantial asymmetry of information between the plaintiffs and class members on the one hand and Grant Thornton on the other, significantly more so than in 'ordinary' commercial litigation. The plaintiffs and class members are very much outsiders to the events within Arasor, and to Grant Thornton's involvement (if any) in alleged misleading statements or representations. They will be at a significant disadvantage if a narrow approach is taken to the scope of discovery.
22 Third, it is inappropriate to characterise the plaintiffs' application for documents relating to the September 2006 Prospectus as a fishing expedition. In Trade Practices Commission v CC (NSW) Pty Ltd (1995) 58 FCR 426 at 438; [1995] FCA 556 Lindgren J said, and I agree, that "fishing" means that "discovery must not be used for the purpose of ascertaining whether a case exists, as distinct from the purpose of compelling the production of documents where there is already some evidence that a case exists". As his Honour observed, the facts of a particular case can sometimes make the distinction between "fishing" and "non-fishing" difficult to discern.
23 In the present case, the plaintiffs have relied on Arasor's publicly available documents to allege a case against Grant Thornton in relation to, amongst other things, representations made in the March 2007 Prospectus. The effect of the plaintiffs' submissions is that they seek documents regarding the September 2006 Prospectus not in order to establish whether a case exists against Grant Thornton concerning its conduct in respect to that prospectus, but in order to make out their pleaded case in respect to the March 2007 Prospectus. That is not "fishing".
24 Fourth, underpinning the relevant allegation against Grant Thornton is the contention that before it made representations in the March 2007 Prospectus, and consented to the inclusion of the material in the September 2006 Prospectus in the March 2007 Prospectus, it was obliged to review its earlier work in relation to the September 2006 Prospectus. On this basis, its documents relating to the September 2006 Prospectus appear to be directly relevant to the issues in dispute.
25 Fifth, the advice provided by the audit expert - to the effect that he or she could not offer an expert opinion regarding Grant Thornton's conduct without the benefit of the entirety of the files including correspondence, working files and time records - is critical. Grant Thornton adduced no evidence from an expert to the contrary.
26 Ms Banton deposed to a conversation between the audit expert and an employee solicitor (which I canvassed at [15]-[16] above). Except in a limited way, Grant Thornton did not adduce evidence to contradict the views attributed to the expert. Ms Yacoubian deposed only that she was instructed by a partner of Grant Thornton that roughly 50% of the paper files and 50% of the electronic audit files are likely to be relevant to the issues raised in the following paragraphs of the ACSOC:
(a) paragraphs 98 and 99 regarding the repeated Prospectus Statements;
(b) paragraphs 109 to 110 concerning the 2006 Annual Report;
(c) paragraphs 130 to 132 concerning the 2007 Half Yearly Review; and
(d) paragraphs 137 to 140 concerning the 2007 Annual Audit.
Ms Yacoubian made no reference to paragraph 143 of the ACSOC.
27 It is central to my decision that the audit expert advised that all parts of an audit are interrelated and that to offer an opinion he needed the entirety of the audit or review files including working papers, correspondence and time records.
28 Sixth, while I must accept the possibility that some parts of the audit or review files may not be directly relevant, if Grant Thornton's approach to the scope of discovery is taken there will likely be further disagreement between the parties, and resultant further delay. Grant Thornton's files are not so voluminous that discovery of them in their entirety will slow the case down. In my view discovery of the entirety of the files is more likely to speed things up.
29 Seventh, there is little in Ms Yacoubian's affidavit which indicates that the discovery sought will be oppressive for Grant Thornton or overly expensive considered in proportion to the complexity of the issues for determination and the potential quantum of the overall claim. Amongst other things:
(a) Grant Thornton's full files are already in electronic form, except for three archive boxes of hardcopy documents that would only take five days to be scanned, coded and uploaded onto an electronic platform;
(b) the full back-up tapes of Grant Thornton's emails and client files have apparently already been extracted and downloaded onto an external hard drive;
(c) it appears that all of the electronic documents will be processed in a form that allows targeted keyword searching by early January 2016; and
(d) the electronic parts of the audit files are accessible by way of remote access to a terminal server.
30 It appears that Grant Thornton has already conducted some necessary searches and is well on the way to being able to make standard discovery, including the contested documents, by early next year. There is little to indicate that the scope of discovery sought would be so onerous or expensive that it would not facilitate the just resolution of the proceeding as quickly, inexpensively and efficiently as possible.
31 Eighth, Grant Thornton seemed to accept that, through the incorporation of representations in the September 2006 Prospectus into the March 2007 Prospectus, documents from the earlier period would be relevant in relation to the March 2007 Prospectus claim, at least insofar as Grant Thornton '"reviewed" those documents on the later occasion. On Grant Thornton's approach the person making decisions as to which documents to discover would be required to decide which documents from the earlier period were reviewed and which were not, which would be a task fraught with difficulty. In my view, if the audit files in their entirety are not produced, it is likely that there will be disputes between the parties in respect of the documents which are not produced with resultant delay and cost.
32 In circumstances where Grant Thornton did not satisfy me that there would be any real oppression, difficulty or undue expense in providing the documents relating to the September 2006 Prospectus, and given the significant delay that has occurred in getting this matter on for trial, I am disinclined to provide room for the parties to engage in further debates about the scope of discovery or about whether any discovery order made has been met. In all the circumstances a bright line approach to discovery is likely to be the most efficient and inexpensive approach.
33 Ninth, Grant Thornton relied on the decision of City of Swan v McGraw Hill Companies Inc (2014) 226 FCR 462; [2014] FCA 1271 ("City of Swan") (Rares J) at [21]-[28]. It contended that documents related to the September 2006 Prospectus are only relevant to the plaintiffs' claim against the Directors and (based on his Honour's remarks in City of Swan) Grant Thornton was not obliged to discover them. I do not accept that Grant Thornton's documents related to the September 2006 Prospectus are only relevant to the claims against the Directors, but even if that statement is assumed to be correct I would not accept Grant Thornton's contention.
34 The proper scope of standard discovery is a matter to be decided consistently with the overarching purpose and objectives in s 37M of the Federal Court of Australia Act 1976 (Cth) ("the Act") and Practice Note CM5. To limit discovery in the way Grant Thornton proposed is likely to give rise to the plaintiffs seeking leave to issue subpoenas requiring Grant Thornton to produce any documents it holds relevant to the plaintiffs' case against the Directors. Alternatively, as Grant Thornton noted, the plaintiffs could seek documents from Grant Thornton relevant to their claims against the Directors by way of an application for non-standard discovery under r. 20.15. Requiring the plaintiffs to subpoena documents from Grant Thornton, or make an application for non-standard discovery, will simply extend the time it takes for the plaintiffs to get access to relevant documents in the case overall, and will make it difficult for the parties to meet the interlocutory timetable set. The need to avoid further delay in this already slow-moving case is fundamental to my decision.
35 It is also worth noting that City of Swan is not on all fours with the present case. It concerned an application by the respondent seeking that one of the applicants review a vast array of documents in its possession by virtue of discovery in a large earlier class action, Wingecarribee Shire Council and Ors v Lehman Brothers, to see whether such documents supported or adversely affected the case of one or other of the co-applicants in the subject proceeding. Rares J refused the application and (at [21]) said that:
… To require a discovering party to give discovery of documents that are directly relevant to issues raised by the pleadings but that do not involve him, her or it, would impose a burden that, in my opinion, would be not conformable with the requirement of r 20.11. That is because such an extended obligation would not facilitate the just resolution of the proceeding so far as it concerned the discovering party and its opponent or opponents as quickly, inexpensively and efficiently as possible.
36 I do not take his Honour to be attempting to lay down an immutable principle that standard discovery under r. 20.14 cannot include an obligation on a party to litigation to make discovery of documents that are directly relevant only to issues between the party seeking discovery and the case of another party to that litigation. I see his Honour's remarks as being directed to the sensible conclusion that the discovery the respondent sought in that case was inconsistent with the requirement to facilitate the just resolution of the proceeding as quickly, inexpensively and efficiently as possible.
37 In any event I am disinclined to agree with his Honour's construction of r. 20.14(2)(c) and (d). The rule requires a party that is subject to an order for standard discovery to discover documents that support or adversely affect "another party's case". The Directors are another party in the present proceeding and the causes of action against the two groups of defendants are to an extent factually and legally interrelated. Grant Thornton must discover documents it holds which are relevant to the case between the plaintiffs and the Directors. Whether to order standard discovery, and the proper scope of such discovery, is a matter to be decided consistently with the overarching principles in s 37M and Practice Note CM5 rather than by reading down the expression "another party's case".
