Background
3 The applicants conduct a business that involves manufacturing, refining and selling ingredients for use in infant formula, supplements and children's foods. They employed the first respondent (Mr Tobias) from around June 1994 to 28 August 2019. On 1 September 2019, Mr Tobias took up employment with the second respondent (Pharmamark), the applicants' competitor.
4 The applicants commenced this proceeding on 21 November 2019. By their statement of claim dated 3 July 2020, they allege, among other things, that Mr Tobias has provided confidential information and assistance to Pharmamark in breach of various duties, and that Pharmamark has been complicit in these breaches. They seek, among other things, damages and an account of profits.
5 On the day that the applicants commenced the proceeding, they also applied for and obtained a search order against the respondents. The search order permitted a search party, supervised by an independent lawyer, to enter the respondents' premises and to copy or seize certain "listed things". The search party was to include independent computer experts (KordaMentha), who were permitted to make copies of the respondents' computer hard drives and to search them for listed things. Where there was a dispute about whether some item was a listed thing, the independent lawyer was to hold it for safekeeping pending resolution of the dispute.
6 The "listed things" were set out in a schedule to the search order, as follows:
1. Documents (whether in tangible and/or electronic form) recording or evidencing (in whole or in part):
(a) the applicants' product formulations,
(b) the applicants' manufacturing equipment,
(c) the applicants' manufacturing specifications,
(d) the applicants' manufacturing processes (including processing steps and operating set points),
(e) the applicants' manufacturing equipment configuration, and
(f) the applicants' manufacturing control documents,
where that thing [is] related to the production of encapsulated oil powders (Applicants' Confidential Information).
2. External storage devices (including USB storage devices) on which is stored any document recording or evidencing (in whole or in part) the Applicants' Confidential Information.
3. Online storage services on which the Respondents have stored, or caused to be stored, any document recording or evidencing (in whole or in part) the Applicants' Confidential Information.
4. Any correspondence or communication in tangible and/or electronic form between [Mr Tobias] and any one or more of:
(a) [Pharmamark];
(b) Guy Drummond;
(c) Ravi Desu,
transferring, disclosing or otherwise communicating (in whole or in part) the Applicants' Confidential Information.
5. Online email accounts with any correspondence or communication between [Mr Tobias] and any one or more of:
(a) Pharmamark;
(b) Guy Drummond; or
(c) Ravi Desu,
transferring, disclosing or otherwise communicating (in whole or in part) the Applicants' Confidential Information.
6. Documents, whether in tangible and/or electronic form, including plans, specifications, drawings or correspondence, in any way relating to the planning, design, construction or set up of:
(a) a manufacturing plant of, or to be used by or on behalf of, Pharmamark; or
(b) manufacturing equipment of, or to be used by or on behalf of, Pharmamark in a manufacturing plant,
which refer to or incorporate the Applicant[s'] Confidential Information.
7. Documents evidencing the employment or other engagement of [Mr Tobias] by Pharmamark.
8. Documents, whether in tangible and/or electronic form, which relate to or evidence any contract, arrangement or understanding between [Mr Tobias] and any one or more of:
(a) Pharmamark; or
(b) Guy Drummond; or
(c) Ravi Desu,
in connection with the planning, design, construction or set up of:
(d) a manufacturing plant of, or to be used by or on behalf of Pharmamark; or
(e) manufacturing equipment of, or to be used by or on behalf of, Pharmamark in a manufacturing plant,
which refer to or incorporate the Applicant[s'] Confidential Information.
7 The search took place on 22 November 2019. Numerous documents were copied from the respondents' computers. These were later uploaded onto a Relativity One database maintained by KordaMentha, where they remain.
8 On 6 December 2019, the court ordered that the applicants provide KordaMentha with a set of filtering criteria that would be applied to the seized documents. This produced an initial subset of documents for consideration. The respondents were then to identify any documents in the initial subset that they objected to the applicants inspecting.
9 On 18 March 2020, the court made orders by consent for the provision of documents between the parties on a confidential basis (the confidentiality regime). The orders relevantly provided as follows:
2. Where in the course of providing:
2.1 a document under these orders or any other orders in these proceedings; or
2.2 any report, affidavit or statement filed or served in these proceedings,
a party ('Disclosing Party') provides to the solicitors of another party ('Recipient Party') any document which the Disclosing Party claims to be confidential and which is marked confidential ('Confidential Document'), the solicitors of the Recipient Party must, unless the Court otherwise orders, keep that document and the information contained therein confidential in accordance with these orders.
3. A Confidential Document, and the information contained therein, may only be disclosed:
3.1 to the Recipient Party's solicitors and barristers who have signed a confidentiality undertaking in the form set out in Annexure A to these orders ('Legal Representatives');
3.2 to administrative staff of, and employed by, the Legal Representatives (provided the Recipient Party keeps a written register recording to which administration staff the document was disclosed, why and upon which date and for what purpose (marking in the register if the documents are copied, the particulars of the copying and to whom same were delivered));
3.3 to any other person, including any officer or employee of the Recipient Party, where the Disclosing Party gives permission in writing and that person has signed a confidentiality undertaking in the form set out in Annexure A to these orders;
3.4 to the Court; or
3.5 if required by law to do so upon giving prior notice in writing to the Disclosing Party.
4. If the solicitors for a Recipient Party notify the Disclosing Party that the solicitors for the Recipient Party wish to provide a redacted form of a Confidential Document (that is, a form of the Confidential Document with the claimed confidential information redacted) to the Recipient Party, the Disclosing Party must also provide a version of the Confidential Document redacted by the solicitors for the Disclosing Party for that purpose within 5 business days of such notification and such redacted version form of the Confidential Document (having had claimed confidential information redacted) will not otherwise be subject to these orders.
5. A Confidential Document, and the information contained therein, may only be used for the purpose of this proceeding.
6. A Disclosing Party may not copy or reproduce, or permit the copying or reproduction of, the Confidential Documents or any part of them other than for the purposes of the conduct of this proceeding.
7. If the Recipient Party asserts that the Confidential Documents and the information contained therein disclosed by the Disclosing Party are not confidential in whole or in part and wishes to deal with the documents or the information contained therein other than in accordance with the Orders, it should give notice to the Disclosing Party in writing of its intention to do so and if the Disclosing Party disputes that those Confidential Documents and the information contained are not confidential in whole or in part, the Recipient Party must comply with these orders until otherwise ordered.
8. If the Confidential Documents are reproduced as exhibits or annexures to any report, affidavit or statement filed or served in these proceedings, they will be identified as confidential exhibits or annexures.
9. If the contents of the Confidential Documents are referred to in written or in oral submissions, they will be identified as such to the Court.
10. The Confidential Documents may only be put in evidence at trial on a confidential basis.
10 The pro forma undertaking in Annexure A to those orders provided as follows:
I, the undersigned, HEREBY GIVE THE FOLLOWING UNDERTAKING to [each of the parties and the court] in relation to any documents provided by a party (Disclosing Party) pursuant to [the confidentiality regime] (Confidential Documents) in Federal Court of Australia Proceedings No. VID1265/2019 (Proceedings):
1. I will not, without the prior written consent of the Disclosing Party or their solicitors, disclose or permit to be disclosed the contents of any of the Confidential Documents, or any information contained in the Confidential Documents, other than in accordance with this undertaking.
2. I will not, without the prior written consent of the Disclosing Party or their solicitors:
2.1 disclose any of the Confidential Documents, or any information contained in the Confidential Documents, except:
(a) to administrative staff of, and employed by me or my firm;
(b) to the Court; or
(c) if required by law to do so; nor
2.2 use any of the Confidential Documents, or any information contained in the Confidential Documents, for any purpose other than this Proceeding;
2.3 copy or reproduce, or permit the copying or reproduction of, the Confidential Documents or any part of them other than for the purposes of the conduct of the Proceedings.
3. Nothing in this undertaking is to restrict or limit otherwise permissible use or disclosure of any information which was within any person's possession or knowledge prior to receiving a Confidential Document, or is publicly available.
4. I will store the Confidential Documents and any copies or reproductions of any of the Confidential Documents, securely in such a way that persons to whom disclosure of these Confidential Documents is not permitted under clause 1 or 2 cannot obtain access to them.
5. If any of the Confidential Documents, or any part of them, are required to be disclosed in the Proceedings or to the Court in any report, affidavit or statement, I will ensure that the Confidential Documents, or any part of them, tendered are included in an exhibit to such report, affidavit or statement marked or designated as 'Confidential'.
6. I will, at the Disclosing Party's option, destroy or return to their solicitors the Confidential Documents and any copy or copies of the Confidential Documents in my possession within 21 days of such request following the final determination of the Proceedings (including, for the avoidance of doubt, any appeal).
(Numbering modified.)
11 Several lawyers acting for the applicants have since given undertakings in the form required by the confidentiality regime.
12 At an interlocutory hearing on 20 May 2020, the applicants sought an order that their lawyers be provided with access to certain documents within the initial subset (see [8] above), subject to the confidentiality regime. The applicants' proposed orders placed the documents into six categories:
(a) documents that Mr Tobias said he had disclosed to third parties (category A);
(b) documents that Pharmamark accepted were listed things, but which were said to contain its confidential information (category B);
(c) documents that Pharmamark accepted were listed things, but which were said to be irrelevant to the proceeding (category C);
(d) documents that Pharmamark accepted were listed things, but which were said to contain its confidential information and to be irrelevant to the proceeding (category D);
(e) documents that Pharmamark said were not listed things (category E); and
(f) all documents in Mr Tobias's list of objections that were not already in any of the other categories (category F).
13 The respondents accepted that the documents in categories A, B, C and D should be provided to the applicants' solicitors, subject to: (a) the confidentiality regime, and (b) the respondents first making reasonable redactions to take into account claims of confidentiality. The applicants agreed to receive the documents on that basis in the first instance. On 29 May 2020, the court made orders accordingly. Since then, the applicants' solicitors have reviewed the documents, but they say that the redactions are preventing them from properly assessing their contents.
14 The 29 May orders also required counsel to confer about inspection of the documents in categories E and F. This was to no avail. On 24 June 2020, the court ordered instead that the category E and F documents be provided to an independent expert, who, in accordance with a protocol proposed by the applicants, was to determine whether each document was: (a) a listed thing, (b) not a listed thing, or (c) not clearly either. The protocol provided as follows:
Appointment of expert
1. The parties propose to appoint a legal practitioner (the Expert) for the purposes of providing a further review of the Category E Documents and Category F Documents (as defined in the Order of Justice O'Callaghan made 29 May 2020 (Orders)) (together, Determination Documents) to determine whether the Determination Documents are 'Listed Things' for the purposes of the Search Order of Justice Wheelahan made 21 November 2019 (Search Order).
Identity of Expert
2. The Expert shall be chosen by the Applicants. The Expert shall be a practising barrister of no less than 10 years' standing, specialising in commercial litigation, and shall be independent of the Applicants' lawyers. The Applicants will notify the Respondents of the name of the Expert within one day of him or her being engaged.
Briefing material
3. Within 7 days, the Applicants shall provide to the Expert a copy of:
3.1 the Search Order;
3.2 the material filed in support of the Search Order;
3.3 the Orders.
Provision of Documents in Categories E & F
4. Within 2 business days of being notified of the appointment of the Expert, Grant Whiteley of Korda Mentha (Independent Computer Expert) shall provide access to the Determination Documents through the Relativity One database and web portal (Web Portal) to the Expert. The Expert may consult with, and obtain assistance from, the Independent Computer Expert at any time to assist in the efficient review of the Determination Documents, as the Expert sees fit.
Technical consultation
5. Where the Expert is unable to determine the status of particular documents as a Listed Thing then the Expert may consult Mr Adam Tyson of Produco Ltd as an independent technical expert (Technical Expert). The details of Mr Tyson can be found at https://produco.co.nz/business-profile/.
Determination
6. As soon as reasonably practicable after receiving the Determination Documents and meeting with the parties, the Expert shall provide a written report to each of the parties in which the Expert indicates:
6.1 which of the Determination Documents are Listed Things for the purposes of the Search Order;
6.2 which of the Determination Documents are not Listed Things for the purposes of the Search Order; and
6.3 for which of the Determination Documents it is not clear to the Expert whether the Determination Documents are Listed Things or not for the purposes of the Search Order.
General matters
7. The Expert does not act as an arbitrator of the matters in dispute and the Determination is not an arbitration within the meaning of any law.
8. The Expert shall keep all information disclosed during the Determination confidential, save as where appropriate that information may be revealed to the Court or, where it concerns confidential information of a party, then that information may be revealed to that party.
9. The costs of the Expert, the Independent Computer Expert and the Technical Expert shall be paid by the Applicants and are reserved.
15 Pharmamark then filed an application for those orders to be stayed, and sought leave to appeal them. The stay application was refused with costs by O'Bryan J on 27 August 2020. See Clover Corporation Limited v Tobias [2020] FCA 1244. The application for leave to appeal was later abandoned.
16 Meanwhile, Mr Benjamin Gardiner of counsel was appointed as the independent expert. He reviewed the category E and F documents, and reported the results of his review to the parties by email on 4 October 2020. He identified 1,247 documents as listed things; 29,460 documents as not listed things; and 1,552 documents as not clearly either (the unclear documents). It is not readily apparent whether Mr Gardiner sought the assistance of the Technical Expert, Mr Tyson, in carrying out his review.
17 Mr Gardiner also noted in his email to the parties that he was open to providing further information or conducting further analysis if required, subject to the consent of the parties or any order of the court.
18 After the parties received Mr Gardiner's report, the applicants' solicitors wrote to the respondents, requesting that they be granted access to those documents that Mr Gardiner had determined to be listed things or unclear documents. The respondents refused that request.
