The defendant had a case of substance, supported by a substantial body of expert evidence. In some instances (Mr Rogers, Associate Professor McKenzie), the evidence of the defendant's experts conflicted directly with the plaintiff's experts. In other cases, the questions were as to the weight to be given to expert evidence on a subject (for instance, epidemiology), in determining the cause of the plaintiff's fibrosis.
The defendant cannot be expected to have been able to predict what my findings would be in determining the various issues regarding the expert evidence. Many of the plaintiff's submissions in support of an award of indemnity costs seem to me to involve, implicitly, expecting the defendant to have been able to do so.
The defendant's conduct in deciding to have the court decide the substantial issues arising from the expert evidence was, in my opinion, not unreasonable and certainly not so unreasonable as to make it just to order indemnity costs.
The plaintiff submitted that the defendant ought to have recognised that it faced a real risk in the litigation. I accept that that is so, but that fact alone does not provide an adequate basis for the award of indemnity costs.
Nor, in my opinion, is the question to be determined (as some of the plaintiff's submissions suggest), by whether the defendant reasonably held the view that it was 'likely' to succeed in its defence. That is a judgment which the court is not well placed to make, in that the views expressed by those who advised the defendant are not available. (The defendant's submissions contain various statements as to what the defendant 'believed' prior to trial, in various respects. As these assertions are not supported by evidence I have not had regard to them.) In any event, a decision to litigate a case of substance which had a reasonable prospect of success (albeit that such prospects were thought to be less than 'even money') in the face of an offer to settle, would not, in the absence of further facts, give rise to a sufficient ground to order indemnity costs.
It follows that I do not accept the plaintiff's submission that 'the defendant having chosen to take the risk of litigating, there ought to be a price to pay beyond party/party costs'. The 'price to be paid' by the defendant includes the excess of its liability under the judgment compared to the settlement offer, its own costs after the offer was rejected, as well as its liability for the plaintiff's costs on a party-party basis. In any case, for the reasons I have sought to explain, I do not consider that the plaintiff's submission in this regard reflects a proper basis for the award of indemnity costs.
This was not an instance where a party's case was doomed to fail, or suffered from a fatal flaw which was pointed out by the other party in the Calderbank offer; see NMFM [87].
The plaintiff emphasised that the defendant rejected his offer within one day of receiving it. In the circumstances of this case I do not consider that that fact affords any support for a conclusion that the rejection was hasty or pre-emptory and so unreasonable in the sense that I have explained.
The plaintiff also submitted that the relative ability of the parties to bear the additional costs of the trial is relevant. I do not accept that the differing means of the parties provides any ground for ordering indemnity costs.
In my opinion, neither the defendant's rejection of the offer of settlement, nor any other aspect of the defendant's conduct referred to in the plaintiff's submissions provides any sufficient basis to order indemnity costs.
The plaintiff seeks, in the alternative, costs on a solicitor-own client basis. No separate submissions were made in support of that application.
For the reasons already stated I am not satisfied that it is appropriate in this case to depart from the usual order for costs on a party-party basis [22] - [33].
