In the "Lym appeal" the first respondent (the first plaintiff at trial) is Lym International and the second respondent (second plaintiff at trial), Ms Yang, was a director of Lym International. The third respondent (third plaintiff at trial), Ms Liu, is the daughter of Ms Yang. The fourth respondent (the second defendant at trial), Westpac Bank, obtained a mortgage over the property on completion of the sale to the appellant. The appellant and his wife and Ms Yang and her husband, Mr Liu (an original shareholder in the first respondent company until he sold his shares to his wife) were friends and business associates. Ms Yang's limited English, her residence in New Zealand and her husband's detention in China meant that in the time prior to the sale she required assistance in dealing with the property and affairs of Lym International. The company had debts relating to development and repayments of mortgages over properties in Mona Vale that needed to be managed. Mr Liu and Ms Yang had also borrowed money from the appellant's company, Heard Park on various occasions, including to make repayments on their mortgages. The appellant then obtained a power of attorney of Lym International from Ms Yang in circumstances where Ms Yang was named, erroneously, as a sole director of the company. Ms Yang signed the contract for sale and transfer to the appellant on behalf of Lym International as its apparent "sole director". At trial, the first, second and third respondents sought to set aside the sale of the property to the appellant.
