Luo v Zhai (No 6)

In Luo v Zhai (No 6), the applicant, Mr Luo, sought to vary an order for costs that had been made in relation to proceedings between him and the second respondent, Mr Zhai. The case was heard in the Federal Court of Australia. The applicant contended that there had been a change of circumstances warranting a variation of the original costs order, which had required Mr Zhai to pay the applicant’s costs. Mr Zhai opposed the application, arguing that the circumstances had not sufficiently changed to justify a departure from the original order.

The court was required to determine whether there had been a change of circumstances sufficient to warrant a variation of the original costs order. The court considered the principles governing the variation of costs orders, including the need to balance the interests of both parties and the importance of finality in litigation. The court assessed the evidence presented by both parties and examined the change in circumstances since the original order was made.

The court found that there had indeed been a material change in circumstances since the original costs order was made. The evidence demonstrated that the financial position of the parties had changed significantly, and the original order was no longer just or equitable. The court emphasised the importance of ensuring that costs orders reflect the true financial positions of the parties and that the orders remain fair and reasonable. Accordingly, the court varied the original costs order and ordered that each party pay their own costs in relation to the applicant’s case against the second respondent.

The court vacated the original costs order and substituted it with a new order that each party bear their own costs in relation to the applicant’s case against the second respondent. This decision underscores the importance of regularly reviewing and, if necessary, varying costs orders to ensure they remain fair and just in light of any changes in the parties' circumstances.
