Counsel then referred to two recent cases in this Court and the High Court.
18 The third matter arose thus:
"PRIESTLEY JA: I wouldn't pursue this, except there seems to be an element in your application for leave of concern on the part of the council in respect of its potential liability for this class of case.
[Counsel for the Council]: Yes, your Honour, I don't run away from that and I understand what's exercising your Honour's mind."
19 That was the line the Council took when it was arguing for leave. But when Priestley JA asked about its attitude to the question whether the leave should be subject to a condition that the Council pay the plaintiff's costs of the appeal in any event, it took a quite different approach:
"We would submit that that's really a matter that ought to be left to the Court of Appeal who hears the case for the reason that it is only then that one can assess whether or not resistance to the application for leave to appeal and resistance to the appeal can properly be assessed.
…
[W]hatever might be the concerns of the council in terms of the wide picture, it's only when the facts of the case are examined and the strengths or weaknesses of the positions adopted by the parties are fully laid out that one can really determine whether or not a special order for costs should be made. When the Court of Appeal hears the matter and examines it all carefully, they may come to the conclusion that it was unreasonable for the plaintiff to resist the appeal, as in any litigation. I say no more than that, your Honour, it really has got to be examined carefully at the hearing of the appeal."
20 The senior counsel who appeared for the Council on the leave application and on the hearing of the appeal did not appear before this Court in relation to the present Notice of Motion. It is not intended to suggest by anything said in these reasons for judgment that he advanced any submission to this Court at any stage which was not a legitimate and entirely appropriate submission.
21 The Court of Appeal was evidently impressed by the first three points raised by the Council on the leave application and not by the last point. Priestley JA and Clarke AJA appeared to adhere at the end to the view Priestley JA had expressed at the beginning. That is why they imposed the costs condition. There was also, incidentally, independent justification at least for an order that the Council pay the costs of the application for leave to extend the time for filing the Summons, that being a matter in relation to which the Council was seeking an indulgence.
22 Both sets of written submissions filed for the Council concede that the Court of Appeal's reasoning in allowing the appeal turned on errors of law made at trial. The reasons for judgment discussed eleven authorities, most of them High Court authorities. Reference was made to the copious discussion of duty of care problems in the United States. The judgment cannot be described as turning on the facts. The errors of the trial judge were legal errors, and indeed they were far from being as obvious and clear cut as the Council now suggests. It would be absurd to suggest that it was unreasonable for the plaintiff to resist the appeal.
23 The basis on which the appeal was decided corresponded with the basis on which leave was granted - the case was seen as one turning on the application of obscure and controversial general principles of tort law to particular facts at a time when the outer boundaries of the tort of negligence, and the reasons why duties of care are imposed and when, are under hot debate.
24 It must be remembered that in attacking the decision of Priestley JA and Clarke AJA to impose the costs condition, the Council is attacking an interlocutory decision. The Council has not shown any error of law or fact, nor demonstrated that any factor which should have been considered was not considered, or that any factor which was considered should not have been considered; or pointed to any injustice in the decision.
25 The Council is wrong in submitting that the fact that the plaintiff resisted leave because he said that the case turned on questions of fact reveals error: however the trial judge expressed himself, his reasoning raised difficult questions of law. The Council is also wrong in submitting that it had never treated the proceedings as a "test case": it naturally embraced suggestions from the court that it was, and gave further reasons of its own for that view. And the Council is also wrong in submitting that the level of its success made it right for the Court of Appeal to depart from the costs condition. That possibility was present when the question of leave being granted, and the conditions on which it might be granted, were under consideration.
26 For those reasons I would reject the Council's application to amend the condition on which leave was granted and would alter the costs order made after the appeal was heard in the general manner desired by the plaintiff.
27 Even if there were any technical or other merit in the arguments of the Council just considered, which there is not, the plaintiff's interests should be protected as he desires for two reasons. First, in resisting leave counsel for the plaintiff realistically pointed to the "emotional stress of having to face up to the possible risk that he may lose his verdict, and not only that, be potentially liable to a crippling costs order". It must be remembered that the plaintiff is aged only about twenty. Between the time when leave was granted and the time when the appeal was decided, the plaintiff could enjoy peace of mind at least to the extent that though he might lose his verdict, he would not be exposed to any costs order in relation to the appeal and would not be under any risk of having to pay the fees of his own legal team. The Council's present attitude will have taken away even that limited consolation. To accede to the Council's argument would be to stimulate a sense of wholly justified grievance in the plaintiff. Any "sense of injustice" which the Council may experience would pale into insignificance beside the plaintiff's sense of grievance. Secondly, the behaviour of the Council in seeking leave, receiving it subject to a condition, acting on the grant of leave to the point of pursuing the appeal to success, and then resiling from the condition, is unacceptable in any litigant, let alone an organ of government.
28 Before the matter was called on for the second time today late in the afternoon, it was my strong provisional view that it should pay the plaintiff's costs from 25 October 2001 on an indemnity basis, and that the following orders should be made:
