Consideration
22 The central point of difference between the parties is as to the relevance or utility of the documents in the NZ proceeding. It was common ground that if the documents, if released, can be of no utility in the NZ proceeding then there would be no reason to release them - no special circumstances would have been established.
23 The first point that is taken by Hills is that the stage at which the NZ proceeding has progressed to is such that the documents would not necessarily be able to be used there. That is because evidence has closed and the documents could only be used with the leave of the ERA. Whether or not such leave would be granted would likely turn, it seems to me, on why the documents had not been produced earlier and the extent to which they are relevant to the issues in that proceeding. No such application can be made until the documents have been released. Thus, it seems to me that the obstacle of leave is irrelevant to my consideration in circumstances where leave is a possibility. The real issue is whether, or to what extent, the documents are relevant to the issues in the NZ proceeding. The more relevant or pertinent they are, the more likely it is that leave will be granted and the more compelling is the case for their release. The reverse is also true.
24 Rauland submits that the Harman documents are directly relevant and highly probative of central issues in the NZ proceeding, namely they potentially constitute direct evidence of the misuse of confidential information. Since the documents cannot be sought by any other means, Rauland submits that they are likely to make a material contribution to the achievement of justice in the NZ proceeding.
25 Hills disputes that characterisation, and submits that none of the documents is shown to be relevant to any claim made in the NZ proceeding. It points to the fact that each of the documents post-dates Mr Delvo's employment with Rauland NZ.
26 With reference to State Street Global, I respectfully agree that it would be undesirable for me to conduct a mini trial about the relevance or admissibility of the Harman documents in the NZ proceeding. That is a matter for the ERA. However, in circumstances where, if relevant, the ERA may allow the documents to be used in the NZ proceeding - whether by way of founding further procedural steps such as discovery, by tender, or in the examination of Mr Delvo or other witnesses - I must be satisfied that the documents have some relevance to the issues in the NZ proceeding before releasing Rauland from its implied undertaking.
27 It is thus necessary to examine the documents to identify what it is that they might establish, and to then analyse whether that is relevant to the issues in the NZ proceeding.
28 The documents tend to show that Mr Law produced Document C which is the document, if any, which contains Rauland's confidential information. He produced that at a time after Mr Delvo's employment by Rauland NZ had ended. The document was then provided to Mr Delvo under cover of Document A on 8 November 2018. It was clearly produced to Mr Delvo for the purpose of his employment with Hills NZ, which was as Enterprise Business Development Manager. I understand that to be a sales role and I infer that it was given to him to use to generate custom for Hills NZ.
29 There is some dispute between the parties as to what Document B shows. Mr Brennan, for Hills, submits that it does not show that Document C was to be used, or was contemplated being used, contrary to the interests of Rauland. He submits that Mr Delvo's email in Document B indicates that he intended to use the document in an effort to establish a partnership with a company referred to as Honeywell to win the business of a "mutual client" to Hills from a company referred to as Austco. On that basis, it was said that even if Mr Delvo had used Document C as contemplated by Document B that would not have been contrary to the interests of Rauland and consequently would not have been in breach of Mr Delvo's employment agreement.
30 I do not accept those submissions. Document C constitutes a comparison of offerings between Rauland and Hills. Use of that document in the market, whether with a prospective partner or to win business from an ultimate client, can on the face of it only be relevant if it is to show that Hills's offering is in some way better than Rauland's. That can only be to Rauland's disadvantage. Further, Mr Delvo's email at Document B specifically refers to the "mutual client" having to choose between Rauland, Austco and Hills. The most obvious inference is that Document C, which by the email Mr Delvo sought authority to use, was intended to be used to win the work for Hills and thus keep or take the work from Rauland and Austco.
31 The question then is whether any of that is relevant to what is at issue in the NZ proceeding. There are some difficulties in that regard. For example, it is not specifically pleaded that Mr Delvo used confidential information of Rauland or Rauland NZ which he obtained after his employment by Rauland NZ ended against Rauland NZ's interests. The confidential information that seems to be at issue in the NZ proceeding is confidential information obtained by Mr Delvo during and as a consequence of his employment by Rauland NZ. Clearly, Document C is not such information.
32 Also, the period of Mr Delvo's restraint of trade is not apparent. It is said in his reply to the amended statement of problem that by December 2018 "a significant portion of the restraint period had already passed". Considering that his employment by Rauland NZ ended on 31 August 2018, it may be that the restraint had already ended by the time of Document B, i.e. 6 March 2019. If the restraint was a six-month restraint then it would have ended at the end of February 2019. That would be consistent with a significant portion of the restraint period already having passed in December 2018.
33 However, and in any event, on Mr Delvo's reply in the NZ proceeding, the restraint, if enforceable - a point at issue in the NZ proceeding, was operative at the time of Document A in November 2018. It was then that Mr Delvo was given Document C. The implication is that he was given it for the purpose of his "business development" role at Hills NZ. Therefore, if it contained Rauland's confidential information then his use of it at that time might have been in breach of clause 23.3 or, more likely, clause 30.2(b) of his employment agreement. That is to say, use of Rauland's confidential information during the period of restraint could constitute doing something to injure or reduce Rauland NZ's business or goodwill.
34 I also note that a "member's minute" of the ERA dated 29 April 2020 states that Mr Delvo will be giving evidence at the hearing, which is described as an "investigation meeting". It is also said that his "evidence on these matters can be tested there". It would thus appear to be the case that the Harman documents, if released, may be able to be used in the examination of Mr Delvo in the NZ proceeding.
35 In the latter regard, I note that under the Employment Relations Act 2000 (NZ) the ERA is an investigative body that has the role of resolving employment relationship problems by establishing the facts and making a determination according to the substantial merits of the case, without regard to technicalities (s 157(1)). It may act as it thinks fit in equity and good conscience (s 157(3)). Also, in investigating any matter it may call for evidence and information from the parties or from any other person and it may in the course of an investigation meeting, fully examine any witness (s 160(1)(a) and (d)).
36 From the above, I infer that the ERA is not likely to be overly technical with regard to pleadings. I therefore do not accept that because Mr Delvo's breach of his employment agreement with Rauland NZ by utilising confidential information of Rauland obtained by him only after his employment ended is not specifically pleaded, documents that might establish such a breach will not be utilised by the ERA. Further, because the ERA is an investigative authority with the powers that I have identified, it may be that it will use the documents in such a way as to procure further documents from Mr Delvo or third parties or to examine Mr Delvo.
37 I do not consider that the fact that the parties to the proceeding before me and the parties to the NZ proceeding are not the same as particularly significant. There is a significant overlap in issues between the two proceedings, and the interests of Rauland and Hills, two parties before me, are both at stake in the NZ proceeding in as much as their subsidiaries or local branches have interests in those proceedings. Simply put, the two proceedings are sufficiently closely related for that to be a factor in favour of, as opposed to against, release of the documents.
38 It is also not apparent to me that the authors of the documents will be relevantly prejudiced by the contemplated use of them in the NZ proceeding. The prejudice that Mr Delvo may face in that proceeding arising out of the use of the documents there is not relevant prejudice as it would be use in the service of the interests of justice in that proceeding.
39 There is an additional consideration. It relates to the overlap in the issues. If Rauland's overall claim is right, which is that Hills has through Ms Johnson and Mr Law and Mr Delvo, all of whom used to work for Rauland or its New Zealand subsidiary, utilised for its own commercial advantage Rauland's confidential information which was in effect stolen from Rauland, that is a very serious matter. Of course, it may be that that proves to be an unfounded case. But its seriousness warrants that it is properly investigated, and that weighs in favour of the ERA having the opportunity to use the Harman documents to get to the truth of the allegations before it, if it should find them helpful.
40 It is also significant that Mr Delvo, a party to the NZ proceeding, is a party to each of the emails and a recipient of Document C. It is more likely, it seems to me, to advance justice in the NZ proceeding to make such documents available to be used there, then to deny the opportunity of their use.
41 There is a further consideration which is that the Harman documents are very likely to be tendered in evidence in this proceeding in due course, unless it is settled. Thus their unavailability for use in the NZ proceeding, thus far at least, is only a happenstance of timing. If the NZ proceeding were to come to hearing only after the final hearing in this proceeding, the documents would be available for use in the NZ proceeding. The Harman documents are not, in contrast, documents that have been caught in a wide net of discovery but which will never become subject to public scrutiny. It seems to me that there is less reason to deny a release from a Harman undertaking in respect of documents which are likely in any event to become public.
42 In summary, in my view there is good reason to release Rauland from its undertaking in respect of the documents.
