The proposed amendments
21 Putting to one side the amendment described in paragraph [16] above, which is not opposed, the amendments seek to add an allegation that IPC Global's copyright in the IMACS firmware has been infringed by Pavetest. IPC Global submits that this is an important amendment and it would be an unsatisfactory state of affairs if all the allegations of copyright infringement by the respondents were not determined in the course of one proceeding. IPC Global submits that the infringement arises out of one course of conduct by the respondents - the development of Pavetest's materials testing equipment (and the software and firmware underpinning it) in circumstances where Mr Sinadinos and Mr Feeley were former employees and/or contractors of IPC Global.
22 IPC Global also submits that the questions of copyright infringement of the Pavetest TestLab software and the source code for the CDAS firmware are inextricably intertwined. It submits that the nature of the amendment is such that both questions are appropriately ventilated in these proceedings. IPC Global submits that it has acted as expeditiously as possible to seek the proposed amendments. It is not necessary to set out the detail of those submissions.
23 The respondents submit that leave to amend (in relation to the amendments concerning the CDAS firmware) should be refused for the following reasons:
(a) IPC Global's new case about the respondents' firmware source code is based substantially on opinion evidence that is, in the circumstances, inherently unreliable;
(b) the circumstances leading to that new case, including the role of the independent expert whose work underpins it, have been inadequately explained, and remain obscure; the Court should infer that the evidence the independent expert could have led would not have supported its new case; and
(c) in the course of building its new case, confidential information of the respondents was exposed directly to IPC Global; the respondents submit that it should not have been exposed to IPC Global in the manner in which it was.
24 The respondents expand on these matters in paragraphs 12-44 of their written submissions.
25 Having considered these submissions, in my view IPC Global should be given leave to amend the amended originating application and the amended statement of claim as sought. The proposed new claim in relation to the firmware is clearly expressed and, on the basis of the material before the Court, arguable. The subject matter is closely related to that of the existing claims, making it efficient and sensible for the new claim to be tried together with the existing claims as part of the one proceeding. In relation to the first matter raised by the respondents (namely, their contention that the proposed new case is essentially speculative), I consider that the affidavit evidence provides a sufficient foundation to bring the claim and that the matters raised by the respondents largely go to the merits of the new case, which is a matter for trial, rather than the question whether leave to amend should be granted.
26 In relation to the second matter raised by the respondents (namely, an alleged lack of transparency about the circumstances in which the proposed new case has come to be pursued), I consider IPC Global to have provided a sufficient explanation of the circumstances in which the new case has come to be pursued. I also consider a sufficient explanation has been provided regarding the timing of the application for leave to amend.
27 In relation to the third matter raised by the respondents (namely, the circumstances of Mr Fernando's access to Pavetest's confidential material), the respondents raise concerns about the disclosure of a document, referred to as a 'Comparison Document', to Mr Fernando of IPC Global. The Comparison Document was prepared by IPC Global's independent expert and contains information which is confidential to Pavetest. IPC Global submits that the disclosure of the document to Mr Fernando was permissible under the confidentiality regime. The respondents accept that IPC Global's interpretation of the current confidentiality regime may be open, but say that it would have been appropriate for IPC Global to have read the confidentiality undertaking narrowly, not liberally, in order to mitigate the risk that the inspection protocol would not achieve its purpose of effectively protecting Pavetest's confidential material - which it had been obliged to discover in legal action brought by its competitor. The respondents submit, in the alternative, that it would have been appropriate for IPC Global to have given prior notice to the respondents of its decision to disclose the Comparison Document to Mr Fernando. In this way, the respondents could have applied to vary the undertaking to prevent the disclosure, or mitigate its impact. I consider these to be matters which should be explored further at a directions hearing, but I do not consider them to be sufficient reason not to permit the proposed amendments to be made.
28 For these reasons, I will grant IPC Global leave to amend the amended originating application and the amended statement of claim in the form of Annexures 'A' and 'B' respectively to the short minutes of orders attached to its submissions dated 22 April 2016.
