3 The offer was not accepted. The third and fourth defendants therefore sought indemnity costs from the date of the offer.
4 The third and fourth defendants submitted that the question for determination was whether or not it was reasonable for the plaintiff not to have accepted the offer. They argued that if it was all but inevitable that the plaintiff would fail in his action against them then it was unreasonable for the plaintiff not to have accepted the offer. Conversely, if it was not all but inevitable that the plaintiff would fail in his action against them then rejection of their offer was reasonable.
5 The plaintiff responded in two ways. First, the plaintiff contended that the Offer of Compromise was invalid, as it did not comply with the rules. This was said to be because the offer did not specifically state that it had been made in accordance with Part 20 rule 20.26. In this respect the plaintiff relied upon the decision of Biscoe AJ in Szabo v Battye (No 2) [2006] NSWSC 1392 at par [15] as follows:
"[15] UCPR 42.15 provides for indemnity costs where a defendant's offer of compromise, made in accordance with UCPR 20.26, is not accepted and the plaintiff obtains a judgment or order as or less favourable than the offer. The defendants' submissions acknowledged that this rule was inapplicable in a case such as the present where the plaintiff has wholly failed. Another reason, I think, why this rule is inapplicable (although not addressed in the parties' submissions) is that Part 22 of the Supreme Court Rules, to which the offer refers, had, as at the date of the offer, been repealed and the offer did not bear a statement to the effect that it was made in accordance with UCPR 20.26, as required by r 20.26(3)(a). . ."
6 Rule 20.26(3)(a) states that a notice of offer, "must bear a statement to the effect that the offer is made in accordance with these rules". It is clear that the offer did not contain a statement that the offer was made in accordance with the rules. The third and fourth defendants contended that the references to "Rules 20.26", "Part 20 Division 4" and "Part 20 Rule 27" operated as, or amounted to, a statement "to the effect" that the offer was made in accordance with the rules. Alternatively, the offer was capable of operating according to its terms as an offer to which the rules did not apply, with like results. For example, the third and fourth defendants presumably relied upon so much of Biscoe AJ's reasoning in Szabo v Battye (No 2) (supra) at par [15] cited above that said:
". . . Nevertheless, an unaccepted and unbettered offer of compromise which is not a formal offer of compromise under the rules - commonly called a Calderbank offer (after Calderbank v Calderbank [1975] 3 WLR 586) - or to which the indemnity costs rules do not apply, may still attract an award of indemnity costs. The question is whether indemnity costs should be ordered because the plaintiff unreasonably failed to accept an offer of compromise: Leichhardt Municipal Council v Green [2004] NSWCA 341 at [52]".
7 For reasons that appear below, I consider that any failure by the third and fourth defendants strictly to comply with rule 20.26(3)(a) is not by itself determinative of the application for indemnity costs. It is important to remind oneself that forms are our servants and not our masters. Even so, the scheme of the rules is such that there ought to be no scope for doubt about the circumstances when a particular offer might provide the foundation for an argument that costs should be payable on an indemnity basis. Although there is a reference to the rules in general, the offer of compromise in this case does not bear a statement to the effect that the offer that it conveys is made in accordance with the rules. It is therefore not in my view an offer to which the rules apply.
8 However, as indicated already, an unaccepted and unbettered offer may still attract an award of indemnity costs. The plaintiff's submissions recognised and accepted this fact. The plaintiff therefore argued, secondly, that he had not unreasonably failed to accept the offer that had been made. The plaintiff emphasised rule 42.15A, which is as follows:
"42.15A Where offer not accepted and judgment as or more favourable to defendant
