The Companies' application for leave to appeal
55 In respect of a grant of leave to appeal from an interlocutory judgment, the two-part test is well-established. Leave should be granted if: (1) in all the circumstances the decision is attended with sufficient doubt to warrant being reconsidered by an appellate court; and (2) substantial injustice would result if leave were refused supposing the decision to be wrong: Décor Corporation Pty Ltd v Dart Industries Inc (1991) 33 FCR 397 ('Décor') at 398-399.
56 For the reasons I am about to state, I do not consider that the decision is attended by sufficient doubt to warrant it being considered by an appellate court at this stage of the proceeding.
57 At the hearing, Mr Wood explained that the proposed appeal centred particularly on the trial judge's finding that one of the Products known as ZeptoLink was developed in breach of Mr Hurd's fiduciary duty to Zomojo. Mr Wood explained that:
… the real nub of the appeal that my clients seek leave to bring is that there was something different about Zeptolink. It wasn't the same as Opticast. There was something different. Her Honour made no findings about what that different thing was and no findings about whether that different thing involved work that was done in breach of fiduciary duties … And the nub of the submission is: it's not just a question of findings of fact.
58 Mr Wood argued that the trial judge's treatment of the ZeptoLink evidence disclosed a number of appellable errors.
59 The first such error was said to be that trial judge "reversed the onus of proof" carried by Zomojo in holding that ZeptoLink was developed in breach of Mr Hurd's fiduciary duties. Mr Wood submitted that, when the trial judge refused, without independent contemporaneous corroborative evidence, to accept Mr Hurd's evidence that: (a) he did not devise ZeptoLink while employed by Zomojo; and (b) Opticast and ZeptoLink were dissimilar, her Honour imposed an impermissible burden on Mr Hurd to "disprove" the allegations made against him.
60 The trial judge's reasons for judgment do not appear to me to justify Mr Wood's assertion that her Honour reversed the onus of proof. It is true that her Honour refused to accept Mr Matthew Hurd's evidence "unless and only to the extent [it was] corroborated by independent contemporaneous evidence": Primary Judgment at [5]. Her Honour's reasons for this were clearly stated at paragraphs 5 and 203 of the Primary Judgment, where her Honour said that:
Hurd was a most unsatisfactory witness. … During the course of his evidence, he admitted on no less than 26 occasions that what he wrote or said was false, a lie or both. But that evidence itself had problems. Hurd's admission that something was false or a lie was itself, often false. [at [5]]
Here, none of the Respondents adduced evidence concerning the design sequence that led to the development of any of their products. Mere assertion that development of a product occurred in or about [x] is insufficient. [at [203]]
On this application, the applicants did not contend that it was not open to her Honour to make this assessment of Mr Hurd's evidence or that her Honour was incorrect about the design sequence evidence.
61 The basis of her Honour's finding that ZetoLink was developed in breach of fiduciary duty was based on her Honour's assessment that there was affirmative evidence establishing, to the requisite degree, that Mr Hurd had acted in breach of his fiduciary duties; and that this evidence withstood Mr Hurd's assertions to the contrary: see [253] to [260] of the Primary Judgment. Whilst her Honour's finding entailed a rejection of Mr Matthew Hurd's evidence concerning the development and nature of ZeptoLink, the rejection of his evidence did not mean that her Honour had reversed the onus of proof. The applicants have not advanced any tenable basis to support their submission that her Honour made an error of this kind.
62 Secondly, Mr Wood submitted that there were significant flaws in the way the trial judge treated the remainder of the evidence on ZeptoLink. These flaws were so significant, Mr Wood submitted, that "when the evidence is examined, it is incapable of supporting the conclusion that her Honour reached". In particular, Mr Wood submitted that her Honour had "ignored" the evidence of Dr Chapman that whereas OptiCast split one signal optically, splitting was effected electronically in the case of Zeptolink. At the hearing, Mr Wood developed this submission to the effect that "her Honour did not take into account the concessions of the applicant's witnesses in the court below". Effectively, this submission expanded the argument to include the evidence of Associate Professor Leong, who agreed that Zeptolink and OptiCast were different as described by Dr Chapman. Particular emphasis was placed on the omission from the judgment of Associate Professor Leong's agreement with the proposition that the Zeptolink device was very different from a regenerative tap.
63 This second submission is again not borne out by the trial judge's reasons for judgment, which clearly show that the evidence was not ignored. At paragraph 260 of the Primary Judgment, her Honour explicitly acknowledges the evidence given by these witnesses, stating that "Chapman and Associate Professor Phillip Leong gave evidence about the two devices." Her Honour expressly recognised that Mr Chapman's evidence was that the devices split the signal differently. Further, her Honour noted that Zeptolink possessed a flexible mapping functionality that OptiCast did not, but that, as Mr Chapman described, this development was simply a "by-product" of the switch to electronic splitting. After noting this evidence, however, her Honour concluded (at [260]):
Despite these differences, I find that ZeptoLink was an evolution of OptiCast for the purposes of cl 10 of the Service Agreement and that it should be assigned to Zomojo.
64 In substance, the trial judge was not persuaded that the evidence of Mr Chapman and Associate Professor Leong established that ZeptoLink was sufficiently distinct from OptiCast to diminish the weight of the other evidence that led her to hold that Mr Matthew Hurd developed ZeptoLink in breach of his fiduciary obligations to Zomojo. This does not mean, as Mr Wood argued, that the significance or substance of their evidence was ignored. Instead, as is apparent from paragraphs [252]-[262] of the Primary Judgment, what her Honour did was evaluate the evidence of two witnesses, in light of the other evidence regarding ZeptoLink.
65 Mr Wood made a third submission about the ZeptoLink evidence, which was in essence that, even if the trial judge correctly characterised Zeptolink as a second generation or 'evolution' of OptiCast, this did not mean that it was developed in breach of fiduciary duty. In support of this proposition, Mr Wood submitted:
…even if her Honour was right to say 'it is impermissible for Mr Hurd to merely deny the allegation' and that that evidence should somehow be rejected, it still fell to the applicant to prove its case to the Briginshaw standard and this means proving that every component, every bit of the Zeptolink device was developed in breach of fiduciary duty.
66 Broadly speaking, Briginshaw v Briginshaw (1938) 60 CLR 336 ('Briginshaw') requires that "the affirmative of the allegation is made out to the reasonable satisfaction of the tribunal", acknowledging that serious allegations "should not be produced by inexact proofs, indefinite testimony, or indirect inferences": Briginshaw at 362. As Dixon J expressly cautioned in Briginshaw at 363, however, "the nature of the issue necessarily affects the process by which reasonable satisfaction is attained".
67 I am not persuaded that a prescription of the kind advanced by Mr Wood can be drawn from Briginshaw. I was not referred to any authority in support of the proposition for which Mr Wood contended, that the proper application of Briginshaw meant that the alleged breach of fiduciary duty must be proved against "every component, every bit" of the device in question. Mr Wood's submissions in this regard failed to satisfy me that her Honour's findings were, on this account, attended by sufficient doubt to justify appellate reconsideration.
68 In this connection, I observe too that her Honour's reasons for judgment specifically noted that "none of the Respondents adduced evidence concerning the design sequence that led to the development of any of their products": Primary Judgment at [203]. Further, as her Honour said at [258]:
I accept that two devices may possess similar qualities while still functioning in different ways. In the end, understanding the way each device achieved the common aim … is unnecessary.
It was unnecessary, so her Honour held, because there was other contemporaneous evidence, namely, the email Snowdon sent to Advantage PCB of 25 May 2011, which contained a description that her Honour accepted as accurate and consistent with Mr Hurd's own admissions of the connections between OptiCast and ZeptoLink: see Primary Judgment at [259]. It is also relevant in this connection to note her Honour's findings at [308]-[309], although Mr Wood made no reference to them in argument.
69 In light of the foregoing, there is nothing in this part of her Honour's analysis that would persuade me that there was sufficient doubt in her Honour's analysis at this point to satisfy the first limb of the test in Décor.
70 Finally, in oral submissions, Mr Wood submitted:
If her Honour was right that the fiduciary duty could continue after Mr Hurd stopped being a director then I have a further hurdle because it may be that whenever this further step was done in the evolution, as I'm describing it, it might have fallen within the period in which the duty was owed. In my respectful submission, a Full Court would have little cause for pause in saying that her Honour was wrong in finding that the fiduciary duty might continue.
In this regard, Mr Wood specifically criticised her Honour's reliance on Cook v Deeks [1916] 1 AC 554 (Cook v Deeks).
71 Her Honour referred to Cook v Deeks at [208] of the Primary Judgment in support of the proposition that:
For directors, fiduciary obligations may continue subsequent to the termination of the relationship that initiated them.
The reference to this authority appears under the heading "Legal Framework" and is unexceptional. The reference appears before her Honour begins her analysis of the facts in the case.
72 In making these submissions regarding Cook v Deeks, Mr Wood failed to refer to her Honour's discussion of the continuing obligation of fidelity in relation to the evolution of ZeptoLink at [308] to [309] in her analysis of liability. Under the heading 'Breach of Hurd's Fiduciary Duties' (above [304]), and the sub-heading 'Development and marketing of OptiCast, ZeptoCast and then Zeptolink' (above [30]), her Honour stated, at [308] and [309], that:
After 11 February 2011, Hurd set about further developing and marketing OptiCast - a product that became known as ZeptoCast and then Zeptolink.
So, for example, after 11 February, Hurd not only continued to design and develop, but was in fact marketing Zeptolink: see [155] above. That conduct continued: see [158], [160], [164], [254] and [256]-[259]. That conduct was, and remained, in breach of the fiduciary duties Hurd continued to owe to Zomojo and s 183(1) of the Corporations Act: Spotless Group Ltd v Blanco Catering Pty Ltd (2011) 93 IPR 235 at [27] …
73 In these paragraphs, her Honour sets outs her finding that Zeptolink was dependent for its evolution on the design of OptiCast; and that this conduct was, in consequence, in breach of a continuing obligation of fidelity to Zomojo because it was an evolution. Her Honour supported this analysis by reference to Spotless Group Ltd v Blanco Catering Pty Ltd (2011) 93 IPR 235 ('Spotless Group') at 242 [27].
74 Perusal of Spotless Group indicates that her reliance on it as authority was well-founded. As Mansfield J said in that case at 242 [27]:
The entitlement of an employee to use information obtained in the course of employment after leaving that employment will depend upon the nature of the information, and the manner in which it is obtained by the employee. The general rule is that, after the employment relationship has ended, a former employee may use know-how obtained in the course of the prior employment. He may not, however, use information of a confidential nature. The situation is different if the information in question, even though it is not strictly speaking confidential information of the employer, is deliberately taken or copied by the employee while the employment relationship persists for use after the employment relationship ceased: Faccenda Chicken Ltd v Fowler [1987] Ch 117 at 136. In that case, a former employee was prevented from using the employer's know-how or non-confidential information that might otherwise have been available for use after termination of the employment relationship, because the information and the advantage that flowed from it was obtained through dishonesty. In such a case, the wide duty of fidelity was said to survive the termination of the contract of employment so that equity will prevent the employee from enjoying the fruits of such conduct.
(Emphasis added.)
The fiduciary duty in the present case continued, so her Honour held, exactly for the reasons put by Mansfield J in the passage set out above.
75 Consequently, even if the exact quality of the ZeptoLink evolution remained unidentified, her Honour found that the evolution itself was in breach of the continuing fiduciary duty that Mr Matthew Hurd owed to Zomojo because it was built on the information that Mr Hurd had dishonestly sourced from the OptiCast device. This finding was, so far as I can discern from what has been put before me on this application, clearly open on the evidence and the authorities.
76 To the extent that it was open to the Companies to renew their application for leave to appeal, I would refuse leave to appeal on the basis that the judgment of the trial judge is not, in the circumstances, attended with sufficient doubt to warrant being reconsidered by an appellate court. It is unnecessary to consider the second limb of the test in Décor. Since I would not grant leave to appeal, I would not grant an extension of time in which to bring an application for leave to appeal.
