Da Yun Xu v Fang Lin

The case of Da Yun Xu v Fang Lin involves a dispute between a long-term client, Fang Lin, and her former business associate, Da Yun Xu. The crux of the matter is whether the sale of a house by Fang Lin to Xu at an undervalued price, facilitated by Xu's exploitative conduct, was unconscionable. Additionally, the court had to determine if the failure to pay a deposit by Xu upon completion of the sale constituted a breach of contract, given that the obligation to pay the deposit had not merged with the completion of the sale. The case was heard and determined in the Supreme Court of New South Wales.

The primary legal issues addressed by the court were the existence of undue influence and unconscionable conduct on the part of Xu, which may have led to the sale of the house at an undervalue, and the nature of the contractual obligations regarding the deposit payment. Specifically, the court needed to decide if Xu's conduct warranted equitable intervention and whether the deposit obligation remained enforceable post-completion. Furthermore, the court considered statutory remedies available under the Contracts Review Act 1980 (NSW) for contracts that may be deemed unjust.

The Supreme Court found that Xu's conduct, which included providing Fang Lin with financial support and engaging in a relationship of dependency, was such that it amounted to undue influence and unconscionable conduct. This led to the conclusion that the sale of the house was at an undervalue and thus, the court granted relief under equity. Regarding the deposit, the court ruled that the obligation to pay the deposit had not been extinguished by the completion of the sale and Xu's failure to pay constituted a breach of contract. Consequently, the court ordered Xu to pay the outstanding deposit to Fang Lin.

In light of the findings, the court ordered that the sale of the house be set aside and that Xu pay the outstanding deposit to Fang Lin. Additionally, Xu was directed to pay costs associated with the proceedings. This decision underscores the importance of equitable principles in protecting vulnerable parties from exploitative conduct and highlights the enforceability of contractual obligations post-completion.
