Application of Willoughby City Council (as manager of the Talus Reserve Trust) and anor

The case involved an application by Willoughby City Council, acting as the manager of the Talus Reserve Trust, and another party seeking to set aside an interlocutory costs order that had been previously made. The court was asked to determine the validity of the costs order in light of an affidavit that had been submitted to the court and later conceded to be erroneous in one respect. The error, however, was immaterial to the basis on which the costs order was made. The court considered whether the error in the affidavit warranted the setting aside of the costs order, ultimately concluding that it did not. The applicant's argument that the error rendered the costs order unjust was rejected by the court, which held that the error did not affect the correctness of the order.

The primary legal issue before the court was whether the erroneous affidavit justified setting aside the interlocutory costs order. The court needed to determine whether the error in the affidavit was material to the basis on which the costs order was made, and if not, whether the order should stand. The applicant argued that the error necessitated a reconsideration of the costs order, while the respondent maintained that the error was immaterial and the order should be upheld. The court's task was to assess the impact of the error on the fairness and correctness of the costs order.

The court found that the error in the affidavit did not affect the correctness of the interlocutory costs order. It held that the error was immaterial to the basis on which the order was made, and therefore, it did not warrant setting aside the order. The court emphasised that the error did not undermine the fairness or the correctness of the decision to award costs. Consequently, the application to set aside the costs order was dismissed. The court concluded that the order remained just and appropriate given the circumstances at the time it was made.

The court's final orders were that the application to set aside the interlocutory costs order was dismissed. The costs order remained in effect, and no further action was required in relation to the costs. The court's decision confirmed that the error in the affidavit, while acknowledged, did not impact the fairness or correctness of the original costs order.
