5 The desirability of encouraging litigating parties to settle proceedings (see Mutual Community Limited v Lorden Holdings Pty Ltd[9]) makes it undesirable that informal offers attracting the Calderbank principles be burdened with technicality. In this case, however, a question has arisen about what the offer was. VicUrban's written submissions, in paragraph 2, described its own offer dated 24 December 2003 as constituting an offer "to settle all of the plaintiff's disputed claims for the sum of $2,721,114 exclusive of GST". Putting to one side whether or not the amount was inclusive or exclusive of GST, VicUrban's own description of its offer in its written submissions was repeated in paragraph 7 as "[t]he defendant's Calderbank offer of 24 December 2003 was for the sum of $2,721,114.00 exclusive of GST." In oral argument, however, counsel for VicUrban moved away from that description of the offer and said that the amount of $2,721,114 was "irrelevant". In oral argument the offer was described by VicUrban's counsel as an offer to pay $4,404,500 on top of what BMD had received to date. VicUrban's offer, if read in the way contended by its counsel in oral argument, has the consequence that the total payable as at 24 December 2003 would have been $18,100,000 whereas, as events have turned out, the total BMD may receive after judgment is $114,314 less because the contract sum on the final certificate was $15,377,700 and the judgment in the proceeding (excluding interest and GST) was $2,607,986.20 (a total of $17,985,686,20). VicUrban contends, therefore, that its offer was more than BMD obtained as a result of the litigation.
