28 While that might be so, it has to be said that the defendants took no steps to raise the question of the indemnity principle either prior to the consent order for costs being made and entered in September 2008, (despite being on notice of the issue when the plaintiff directed that the judgment debt and interest be paid directly to the AOC Inc in June 2008), or thereafter for 12 months until August 2009, preferring, it seems, to wait and see whether the plaintiff would seek to recover his costs by filing a bill of costs as part of the assessment process.
29 Subject to the principle of res judicata to which I will presently refer, it would have been open to the defendants under s 98(4) of the Civil Procedure Act to bring an application to have the plaintiff's right to recover his costs determined in this Court in accordance with the approach that Austin J considered appropriate in Australian Beverage Distributors v The Redrock Co [2008] NSWSC 114. In that case his Honour, after finding in the defendants' favour in the primary proceedings, ordered that the plaintiff pay the defendants' costs as agreed or assessed. He did however allow the plaintiff liberty to restore the matter before him to settle the question, raised late in the proceedings, as to whether the indemnity principle had any application. Thereafter, the plaintiff filed a notice of motion seeking orders reviewing or revising the costs order
30 Although his Honour acknowledged there may be a question as to the appropriateness of the procedure employed by the plaintiff, he did not explore the issue having resolved to determine the question on what he described as "the substance of the evidence". He went on to say:
In a case where the application raises a question relating to evidence given at the trial reflected in the court's findings in its principal judgment, and the assessment of costs by a costs assessor has not been commenced, my view is that the trial judge has the power to deal with the application, and ought to do so (Civil Procedure Act, 2005 (NSW), s 98(1)(b); Wentworth v Rogers (2006) 66 NSWLR 474, at 512-4 per Basten JA; cf 485-7 per Santow JA). In my view none of the "floodgates" problems adverted to by Basten JA in Wentworth v Rogers (at 514) has any application here.
31 In the present case, although in a practical sense the costs assessment process has not commenced (or if it has, it has not progressed any distance such as might otherwise justify this Court refusing to consider the application), this is because the defendants have moved unilaterally to have the costs assessor defer the assessment against the plaintiff's opposition. While there might have been at one time sound reasons for taking this approach (in the sense that it was thought evidence might need to be led orally in the process of determining whether the indemnity principle has any application), in the result that has not proved to be the case. That said, in the particular circumstances of this case and despite the largely unexplained delay in the plaintiff seeking a costs assessment, I do not consider the breadth of the power under s 98(1)(b) of the Civil Procedure Act should be read down. I am satisfied that the parties should be afforded the opportunity now to have the question of the application of the indemnity principle determined.
