The parties' submissions
28 The applicants pressed for discovery orders against the first and third respondents. In support of their interlocutory application, the applicants submitted that the standard discovery order required a party to discover documents that supported its own case or adversely affected its own case. If the first respondent did make sales of any products, contrary to its untested assertions, those documents would plainly support the applicants' case and were discoverable. If the first respondent's financial documents and sales records recorded that they did not sell a single item from the infringing catalogue, that would adversely affect the applicants' case on damages. Either way, the applicants submitted, the documents were discoverable and ought to have been discovered.
29 The applicants drew attention to an unsworn statement of Mr Han which was in evidence as CL2-1 to the affidavit of Ms Carrie Lee affirmed 21 September 2018. There Mr Han said that Han's Pipe Fittings issued purchase orders, invoices and receipts describing the goods sold by it to its customers. What the applicants wished to test, they submitted, was whether a connection could be drawn on the documents between the infringing website and the orders placed, or the receipts given. If documents were ordered by reference, for example, to the identifying numbers on the infringing website then that would torpedo the case theory of the respondents that, in their view, no one ever went and looked at the website.
30 As to the financial information, paragraphs a, b and c of the schedule, the applicant submitted that there was an element of competition between the applicants on the one hand and the respondents on the other and the financial material may suggest that Han's Pipe Fittings sold only three units over the whole of the period of the infringement or it may show that it made no profit at all, or it may show that there was a huge spike in sales and that those sales were commensurate with other evidence that may demonstrate that they were sales foregone by the applicants. The applicants submitted that the assertion that these documents were not properly discoverable rested on an unsworn assertion that there was no connection between the infringing website and the sales that had admittedly been made, and that was what the applicants wanted to test by reference to the primary documents. The applicants submitted that those documents would be capable of showing an increase in sales that would correspond to the infringement. The financial material may demonstrate an increase in sales that had a temporal connection with the infringement. They would not necessarily show that those sales were connected with the catalogue but were a necessary first step in the applicants' attempt to prove damage.
31 In the alternative, the applicants sought a further order for discovery. They submitted that they should not be left with the respondents' untested assertion as to what sales took place. The applicants submitted that the question of what items were sold was peculiarly in the knowledge of the respondents and it was only through the Court's compulsory processes that the applicants would be able to determine the level of sales. The sales of the first and third respondents were relevant to the claim for account of profits, and were necessary to inform the applicants' election between that remedy and damages. Further, the submission went, the documents were relevant to any claim for damages. If the respondents enjoyed sales of products from the catalogue that roughly corresponded to a drop off in sales enjoyed by the applicants, that would be relevant to the assessment of damages. Conversely, if the respondents made no sales, or made very few sales, that would be highly relevant to the assessment of damages.
32 The applicants submitted that in the event that the Court was minded to make an order for discovery under either of those two grounds, the claim for a further affidavit under r 20.21 was not pressed. That order was sought, in the alternative, in the event the discovery was not ordered.
33 The respondents submitted that they had satisfied their obligations of standard discovery; inadequate reasons had been shown to justify an order for non-standard and more extensive discovery against the respondents under r 20.15; and that the filing and service of affidavits under r 20.21 in the terms offered by the respondents should be ordered.
34 As to standard discovery, the respondents submitted that the affidavits verifying their lists of documents ought be found (subject to a r 20.21 order) to be conclusive for interlocutory purposes as to the non-existence of documents evidencing such sales. There was no basis for the requisite degree of certainty that the respondents had misconceived the nature of the documents to be discovered under the orders of 4 July 2018. Nor had reasonable grounds been shown so that the Court could be fairly certain that such sales documents were or had been in the control of the respondents. The pleadings and the evidence were not capable of supporting such conclusions.
35 The respondents submitted that if their affidavits verifying their List of Documents were conclusive in this way, it followed that the financial records of the respondents ought be taken as dealing with entirely different transactions and were not even indirectly, less still, directly relevant.
36 In relation to an order for non-standard or more extensive discovery following satisfactory standard discovery, the respondents submitted that such an order needed to be adequately justified by an applicant, not least, the respondents submitted, on the basis that it would facilitate the just resolution of the proceeding as quickly, inexpensively and efficiently as possible; referring to r 20.11 and also Practice Note CPN-1 at [10.6].
37 The respondents submitted that an application for such an order must be accompanied by, amongst other things, an affidavit stating why such an order should be made and there was no such affidavit in the present case. Moreover, the respondents submitted, the applicants had not complied with r 20.15, identifying the matters there specified. Even if the Court excused those procedural deficits, the merits of making the r 20.15 orders sought were lacking. First, this application was a "fishing" exercise which the Court should refrain from assisting. Secondly, the orders sought lacked sufficient prospect of advancing the interests of justice, but at the same time came at a significantly higher price in terms of delay, expense and inefficiency in the proceeding. Further, on the basis of the respondents' material, the orders sought were too wide.
38 As to r 20.21, the respondents submitted that orders by the Court in terms of paragraph 1 of the respondents' open offer would now be appropriate. The terms of that offer were that each of the respondents, without admission that they had failed to satisfy their obligations of standard disclosure pursuant to the orders of the Court made on 4 July 2018, file and serve an affidavit stating that no document evidencing sales by reason of the post-June 2015 alterations and additions to the www.maxiflo.cn website was or had been in their control.
39 The respondents submitted that if the applicants at trial managed, in their own case, to adduce evidence of infringing sales, the presence of these affidavits pursuant to r 20.21 would fairly facilitate a challenge to the credit of the respondents' witnesses and, in particular, of Mr Han and Mr McCormick.
