Sino Synergy Investment Company Limited v Maygood Australia Pty Limited; Limei Wang Lee v Yehan Koo; Yi-Fawn Lee v Yehan Koo (No. 2)

In the matter of Sino Synergy Investment Company Limited v Maygood Australia Pty Limited; Limei Wang Lee v Yehan Koo; Yi-Fawn Lee v Yehan Koo (No. 2), the parties contested issues relating to the calculation of interest following a principal judgment and the apportionment of costs. The case was heard in the Supreme Court of New South Wales.

The central legal issues before the court involved determining the appropriate date from which interest should be calculated post-judgment, whether interest should be compounded, and the appropriate allocation of costs between the parties. Specifically, the court had to decide if Sino Synergy Investment Company Limited was entitled to indemnity costs and, if so, what the appropriate apportionment of costs should be given that Sino was unsuccessful in some of the proceedings.

In delivering the judgment, the court examined the precedent set in the original case and the principles of equity that guide the calculation of interest and costs in such scenarios. The court ruled that interest should be calculated from the date of the principal judgment, rejecting the notion of compounding interest. Regarding costs, the court held that Sino was entitled to indemnity costs for the successful parts of the proceedings but determined an appropriate apportionment for the unsuccessful parts, balancing the overall outcome and the conduct of the parties throughout the litigation.

The final orders included the calculation of interest from the date of the principal judgment without compounding and an apportionment of costs, with Sino receiving indemnity costs for the successful claims and a specified proportion of the costs for the unsuccessful parts.
