(c) That after those products had been brought into existence by him, he had compared their performance and characteristics with competitors and had concluded that his products were superior.
36 On the basis of this material, the experts retained by the company plaintiffs whose reports have previously been served, calculated a huge loss of profits.
37 The defendants submit that this approach was deliberately chosen because of the difficulties which it posed for them in meeting it. Such assertions by Mr Chaina, of their nature, were difficult to refute. They depended very much upon Mr Chaina being accepted. If he were, then the claim of the company plaintiffs was largely made out.
38 The revelation that Mr Chaina does not have any university or academic qualifications must place in doubt many of his other assertions. This was a risk always inherent in the way in which the case on behalf of the company plaintiffs had been conducted up to this point in time. The defendants submit that the company plaintiffs should accept the consequences of this deliberate tactic which has been followed for the last seven years and should not be allowed at this late stage to change the entire evidentiary basis for their claim.
39 The second reason for opposing the applications is that the additional expert evidence which has been foreshadowed will inevitably be based on formulae which are of themselves defective. The existence and content of the formulae depend on the evidence of Mr Chaina being accepted. The formulae are not complete. Mr Williams and Mr Van Dyke have to reconstruct products from these formulae as they were alleged to have been in 1999 in circumstances where many of the original ingredients can no longer be sourced. The defendants submit that even if the company plaintiffs are allowed to adduce this expert evidence, it will have little probative value.
40 The defendants submit that the last of the evidence on behalf of the company plaintiffs was served in October 2006. Before that date, but most particularly since that date, the defendants have been seeking particulars and documents to enable them to serve their evidence in chief to meet that evidence. Their efforts in that regard have been frustrated by the conduct of the company plaintiffs in refusing to provide the formulae and when failing in that endeavour, in challenging their use of Dr Wynn-Hatton. Nevertheless, the defendants have endeavoured to meet the case which was put forward by the company plaintiffs. If this application is successful, almost all of that work by the defendants will have been wasted.
41 The defendants rely upon the provisions of the Civil Procedure Act 2005 (CPA) in particular, sections 56-59 and s 61. Those sections stress that "the overriding purpose of this Act and of the rules of Court in their application to civil proceedings, is to facilitate the just, quick and cheap resolution of the real issues in the proceedings" (s 56(1)).
42 The defendants submit that the giving of leave to file fresh evidence in chief more than seven years after the commencement of the proceedings, after extensive case management by the Court and ten years after the accident, would be contrary not only to the spirit of those sections but to their content.
43 In that regard the defendants rely upon the decision of the High Court in Aon Risk Services Australia Limited v Australian National University [2009] HCA 27. The defendants relied upon the statement of principle by the plurality as follows:
"111 An application for leave to amend a pleading should not be approached on the basis that a party is entitled to raise an arguable claim, subject to payment of costs by way of compensation. There is no such entitlement. All matters relevant to the exercise of the power to permit amendment should be weighed. The fact of substantial delay and wasted costs, the concerns of case management, will assume importance on an application for leave to amend. Statements in J L Holdings which suggest only a limited application for case management do not rest upon a principle which has been carefully worked out in a significant succession of cases. On the contrary, the statements are not consonant with this Court's earlier recognition of the effects of delay, not only upon the parties to the proceedings in question, but upon the court and other litigants. Such statements should not be applied in the future.
112 A party has the right to bring proceedings. Parties have choices as to what claims are to be made and how they are to be framed. But limits will be placed upon their ability to effect changes to their pleadings, particularly if litigation is advanced. That is why, in seeking the just resolution of the dispute, reference is made to parties having a sufficient opportunity to identify the issues they seek to agitate.
113 In the past it has been left largely to the parties to prepare for trial and to seek the court's assistance as required. Those times are long gone. The allocation of power, between litigants and the courts arises from tradition and from principle and policy . It is recognised by the courts that the resolution of disputes serves the public as a whole, not merely the parties to the proceedings.
114 Rule 21 of the Court Procedure Rules recognises the purposes of case management by the courts. It recognises that delay and costs are undesirable and that delay has deleterious effects, not only upon the parties to the proceedings in question, but to other litigants. The Rule's objectives, as to the timely disposal of cases and the limitation of cost, were to be applied in considering ANU's application for amendment. It was significant that the effect of its delay in applying would be that a trial was lost and litigation substantially recommenced. It would impact upon other litigants seeking a resolution of their cases. What was a "just resolution" of ANU's claim required serious consideration of these matters, and not merely whether it had an arguable claim to put forward. A just resolution of its claim necessarily had to have regard to the position of Aon in defending it. An assumption that costs will always be a sufficient compensation for the prejudice caused by amendment is not reflected in r 21. Critically, the matters relevant to a just resolution of ANU's claim required ANU to provide some explanation for its delay in seeking the amendment if the discretion under r 502(1) was to be exercised in its favour and to the disadvantage of Aon. None was provided."
44 In line with those sections of the CPA and the statements of principle in Aon, the defendants submit that they have devoted significant costs and resources over three years since October 2006 to preparing to meet the case thus far put forward by the company plaintiffs. They submit that if the company plaintiffs are permitted to serve further evidence, they will be forced to incur further significant costs and will likely be obliged to seek further orders for particulars and discovery. They will need to carry out their own manufacturing and testing at great expense.
