Offers of compromise in this Court
12 Part 51 of the rules now provides that any party in this Court may make an offer to any other party to compromise any claim in the proceedings, in whole or in part, on specified terms: r 51.47(1). Part 51 does not, however, provide a framework for making such an offer but rather provides that the general provisions in Pt 20, Div 4 apply, subject to "modifications", some of which are specified but others of which may not be: see r 51.47(2). Relevantly for present purposes, a reference in Pt 20 to a "plaintiff" is a reference to an appellant or cross-appellant in this Court and a reference in Pt 20 to a "defendant" is a reference to a respondent or cross-respondent in this Court. It follows that in relation to both Erect Safe and Australand, Mr Sutton was a "defendant".
13 However, a different principle applies in relation to the operation of Pt 42 which respect to the consequences for costs orders where an offer has been made. Thus, in the case of appeal proceedings, references in Pt 42 to the "plaintiff" and "defendant" are references to the party who was a plaintiff or defendant respectively in the Court below: r 51.48(1)(d). This drafting device has some curious consequences: for example, in considering the validity of an offer of compromise, under r 20.26, a reference to "the plaintiff's claim" will be treated for the purposes of r 51.47 as a reference to the appellant's claim. However, for the purposes of Pt 42 a reference to a "plaintiff's claim" will be a reference to a claim made by the plaintiff in the court below. It does, however, follow that the offer made by Mr Sutton was an offer made by "the plaintiff" and hence, the offer not being accepted, the costs consequences are to be derived from r 42.14, as the parties accepted.
14 A second problem arising from the adoption with modifications of the rules in Pt 42, Div 3 with respect to costs concerns the treatment of interest. That issue arises because the comparison required by the rules is to be made between the terms of the offer and the judgment on the claim. In order to undertake the required comparison, the amount of interest contained in the judgment and attributable to the period after the day on which the offer was made is to be disregarded: r 42.16(1). Where an offer is made before judgment, it will therefore be treated as including any amount of interest which would be included in a judgment given on the date the offer was made. However, a judgment does not include post-judgment interest, as explained above. Accordingly, where an appeal is dismissed, or where it is upheld but back-dated to the date of the trial judgment, a difficulty arises in the comparison required between the judgment and the offer which is, in effect, a post-judgment offer.
15 Because the parties cannot confidently predict whether the outcome of an appeal will operate from the date of judgment in this Court or from an earlier date, the only way that an offer of compromise could cope with this problem would be to make a separate offer with respect to a claim for interest. It may be possible to divide an offer in this way, but it seems undesirable to enforce it on parties to an appeal. The preferable course is to proceed on the basis that r 42.16 is subject to an additional necessary modification, in accordance with r 51.48(h), which permits such other modifications. The relevant modification, where the judgment of this Court is back-dated, is to identify the amount of a notional judgment, including interest (but subject to no other variation) which would have been given had judgment been delivered on the date of the offer. That calculation is not dissimilar to the calculation required where there has been a separate judgment with respect to an amount excluding interest: see Atkinson v Zey; Zey v Atkinson [2008] NSWCA 30 at [4].
16 A further question arises with respect to costs. Because the rules make their own provision with respect to the costs of proceedings, both where an offer has been accepted (r 42.13A) and where it is not accepted (r 42.14-42.15A) a valid offer under Pt 20 must, except where there is to be "verdict for the defendant and … the parties are to bear their own costs" be "exclusive of costs": r 20.26(2). The rationale for this provision is that an inclusive offer would be inconsistent with the legislative scheme: see, in relation to a previous rule, Associated Confectionary (Aust) Ltd v Mineral and Chemical Traders Pty Ltd (1991) 25 NSWLR 349 at 350-351 and Atkinson v Zey at [6]-[7].
17 Despite the reference to a verdict for the defendant, with each party to bear its own costs, there seems to be no reason, in principle, why an offer could not be made by a plaintiff seeking a judgment, but agreeing to waive any entitlement to costs, if the offer were to be accepted. An offer made prior to trial, and expressed to be "plus costs" may be intended to do no more than make it clear that the offer is not inclusive of costs, but that an entitlement to costs will flow pursuant to the rules. However, an offer expressed in this way after trial involves new elements of uncertainty. For example, is the reference to "plus costs" intended to refer to the costs of the trial, or to the costs of the appeal? As there was no contention that the costs of the trial were to be taken into account, the only question relevant for present purposes concerns the costs of the appeal as to which the submissions are addressed below.
