Background
6 In this proceeding, the ACCC alleges that each of BlueScope and Mr Ellis attempted to induce certain suppliers of flat steel products in Australia to make an arrangement or arrive at an understanding that contained a cartel provision in contravention of s 44ZZRJ of the Competition and Consumer Act 2010 (Cth) (Act). The period of the allegedly infringing conduct was September 2013 to June 2014. Amongst other forms of relief, the ACCC seeks pecuniary penalties against the respondents. As an individual, Mr Ellis has until recently claimed the privilege against self-exposure to a penalty and has elected not to file an affidavit or witness statement in the proceeding.
7 The trial of the proceeding commenced on 30 August 2021. The ACCC closed its case on 17 September 2021. On the application of Mr Ellis, which was not opposed by the ACCC, the trial was adjourned until 23 September 2021 to provide Mr Ellis with a short period of time to decide whether he wished to waive his privilege and give evidence in the proceeding. On the evening of 21 September 2021, Mr Ellis notified the Court that he proposed to give evidence in the proceeding and that an affidavit would be filed and served on 22 September 2021. As it turned out, there was some delay in the filing and service of the affidavit, but it was received by the Court and the parties on the morning of 23 September 2021. The affidavit is unsworn but includes a notation that, in accordance with paragraph 4.2 of the Federal Court of Australia Special Measures Information Note (SMIN-1) dated 31 March 2020, the affidavit is filed and served on the basis that Mr Ellis has read it carefully, is willing to swear that it is true and correct, and understands that he will be required to swear its accuracy at the hearing. It is anticipated that Mr Ellis will give evidence in the week commencing 27 September 2021, and he will be cross-examined by the ACCC.
8 On 22 September 2021, BlueScope filed and served an affidavit of Paul Bickley affirmed 22 September 2021 which BlueScope seeks to read in its case. Mr Bickley is the Head of Global Security Operations for BlueScope. Mr Bickley exhibits to his affidavit copies of Microsoft Outlook calendar entries dated between 29 July 2013 and 3 November 2013 and an entry on 8 April 2014 for Mr Ellis. Counsel for BlueScope explained that Mr Ellis kept his diary for work purposes in electronic form using Microsoft Outlook software. Mr Bickley's affidavit exhibits Mr Ellis' diary for the periods stated above. Counsel for BlueScope submitted that the diary evidence is relevant to two issues that have arisen on the ACCC's case: whether a meeting occurred between Messrs Ellis and Hennessy of BlueScope and Messrs Collis and Gregory of Selection Steel Trading Pty Ltd at BlueScope's head office in Mount Waverley in August or September 2013 (but prior to 13 September 2013); and the extent of Mr Ellis' commitments on 8 April 2014.
9 In his affidavit, Mr Bickley explained the source of Mr Ellis' Microsoft Outlook calendar entries. Mr Bickley deposed that, in April 2016, he instructed Computer Science Corporation (CSC), an external information technology service provider which supplied and managed the servers and data storage facilities for BlueScope, to export the mailboxes of three BlueScope employees from BlueScope's Microsoft Exchange server, including the mailbox of Mr Ellis. CSC carried out that instruction, and the file was exported as "Jason.pst" and contained 2 gigabytes of data. On 22 September 2021, Mr Bickley was instructed by Gilbert + Tobin to obtain copies of Mr Ellis' Microsoft Outlook calendar entries for the period 29 July 2013 to 3 November 2013 and 8 April 2014 from Mr Ellis' mailbox, and Mr Bickley extracted those entries from the file "Jason.pst" that had been created in 2016 and created a PDF version.
10 In her affidavit, Ms Garling deposed that Microsoft Exchange software provides an integrated system for creating and storing email and electronic calendars, messaging and task lists. The software utilises a personal storage folder (.pst file) which is a single data file that contains a record of a user's messages, emails, calendar entries, contacts and other tasks for a particular period of time. The size of the "Jason.pst" data file is 2.6 gigabytes and contains approximately 13,000 messages, emails and calendar invitations and the date range of the "Jason.pst" data file covers at least the period 21 August 2010 to 14 April 2016. Ms Garling gave similar evidence about an equivalent data file in respect of Mr Hennessy called "Matthew.pst" which is no longer sought by the ACCC. Ms Garling further deposed that, based on her experience in large and complex document reviews, her best estimate is that it would take Gilbert + Tobin:
(a) at least two to three days to upload the Jason.pst and Matthew.pst files to their Ringtail database and prepare the documents for review by a legal team; and
(b) between four to six weeks to review the approximately 26,000 files in the "Jason.pst" and "Matthew.pst" files to ensure, among other things, that appropriate claims are made by BlueScope in relation to privilege, commercially sensitive and/or confidential documents.
11 I consider that Ms Garling's estimates may be on the generous side, but even excluding the review of the "Matthew.pst" file, I accept that an appropriate review of the "Jason.pst" file for the purposes of relevance and privilege would take up to two weeks. It follows that, if the ACCC's notice to produce were not set aside and BlueScope's solicitors were give an appropriate period in which to review the documents within the "Jason.pst" file before production (or before the documents were released to the ACCC), the trial would have to be adjourned for that period which is likely to be at least 2 weeks.
12 Ms Garling further deposed that, prior to the commencement of this proceeding, the ACCC issued ten notices under s 155 of the Act which sought production of information and documents from BlueScope and that, in response, BlueScope produced approximately 20,428 documents. I note that, in a notice dated 11 April 2016, the ACCC sought production of copies of all documents, including but not limited to diary entries, emails, mobile phone text messages, notes or records (in any form) and/or documents that plan for, refer to, report or otherwise arose from meetings or communications that occurred or were scheduled to occur in the period from 1 September 2013 to 1 July 2014 between (amongst others) Mr Ellis and/or Mr Hennessy on the one hand and representatives of competing suppliers of steel products in Australia on the other. Ms Garling also referred to the orders for discovery made by the Court by consent on 7 July 2020 which resulted in the production of a further 3,533 documents by BlueScope.
13 In the course of submissions, counsel for the ACCC did not advance a submission that the ACCC considered that BlueScope was in default of discovery orders.
14 In his affidavit, Mr McHugh deposed to the execution of a search warrant at the residential premises of Mr Ellis on 22 September 2017 and the electronic devices that were imaged pursuant to that warrant. In his affidavit, Mr Steger contested whether Mr Ellis' laptop or phone were imaged in the execution of the search warrant. It is unnecessary to address that matter in the resolution of the interlocutory application.
