11 As can been seen from the judgment of 30 October 2006, the circumstances in which the advances were made, and the circumstances of the December 1994 agreement, were not entirely irrelevant to the claim as ultimately prosecuted. However, although there was some overlap between the factual context of those aspects of the plaintiffs' claim which were ultimately pursued, and those which were abandoned, the manner in which the original claims were made and prosecuted raised issues far more extensive than those which were ultimately litigated at the final hearing, and necessitated the incurring of costs which would not have been necessary had the plaintiffs' claim originally been framed as it ultimately was pressed in a much more limited and confined manner. I do not think that there is any room for doubt that the claims for breach of fiduciary duty in respect of the "unauthorised loans" necessitated a considerable amount of work, and incurred considerable costs, on both sides, which would have been avoided, had the claims been limited as they ultimately were. That has additional significance in this case, where there had been a settlement of the dispute about the unauthorised loans in the December 1994 agreement. The ultimate success of the plaintiffs has been by suing on the very agreement the denial of which was an essential basis of their earlier claims. In this case, the nature and extent of the issues on which the plaintiffs failed are such that justice requires that the plaintiffs not only be deprived of at least some of their costs on the issues on which they failed, but pay at least some of the Fiala Estate's costs of those issues. The plaintiffs' acceptance that they should bear at least some of the Fiala Estate's pre-trial costs effectively acknowledges that view.
12 I have concluded that this should apply only to a proportion - albeit a large proportion - and not all of the costs of the issues on which the plaintiffs failed, because I accept that the plaintiffs' decision to abandon their case on the "unauthorised loans" was due, in part, to the defendants being permitted to raise, by a relatively late amendment, a Limitation Act defence. On 9 February 2006, the Lederer Estate advised the plaintiffs by letter that it proposed to amend its defence, including by raising a limitation defence. It filed a notice of motion seeking leave to amend on 17 March 2006. On 23 March 2006, I gave leave to the Lederer Estate to amend its defence to raise, in answer to any claim for equitable relief, a time bar by analogy with Limitation Act 1969 (NSW), s 15(1). The Lederer Estate's defence already contained a plea of Limitation Act, s 14, and of laches. In the judgment of 23 March 2006 [Hexiva Pty Ltd v Lederer [2006] NSWSC 318], I said:
31 Proposed paragraph 57A will make those issues relevant in a different legal way, but it raises what is, in essence, a legal defence which will not depend on the facts. Whether in fact s 15(1) is capable of application by analogy at all will be a matter for debate at the trial.
