The widow of Cantonese opera star Tang Wing-cheung launched a legal battle against her daughter over a family business yesterday. Hung Jin-mui petitioned in the Court of First Instance as a minority shareholder to wind up Chor Lau Heung Restaurant in Sai Wan Ho, which was founded by her husband, Tang Wing-cheung, who died in 1997 aged 81. But other owners of the restaurant, including her daughter Angela Tang Chui-yuk, opposed her petition. Benjamin Yu SC, for the other restaurant owners, said they were willing to buy Ms Hung's shares, which are not of substantial value, in order to settle the matter, but the offer was not accepted by Ms Hung. Counsel Jason Pow, for Ms Hung, suspected the offer was not genuine but simply an attempt to limit the petitioner's choice of remedies. He also said the restaurant had been running at a minor loss. Mr Pow said as the parties' relationship had broken down and they no longer trusted each other, there was no good reason to bind them in a joint business and they should be allowed to separate. There were also factual disputes to be dealt with by the court, Mr Pow said, including Ms Hung's allegation of misappropriation of funds from the restaurant. Ms Hung testified yesterday that she became a director of the restaurant only in December 1994 but had actively handled the operation long before that. The hearing before Mrs Justice Doreen Le Pichon continues today.
