THE Court of Appeal ruled yesterday that a Hunghom mahjong club where six men were killed in an arson attack in 1990 must pay compensation to the families of four of the victims, who were employees. King Ford Mahjong Club had argued that Lam Wai-lap, 29, Yim Sze-tung, 27, and Leung Ping-wah, 30, were not on duty at the time, and the death of Tai Kwok-ching, 39, did not arise out of his employment. They died when three men poured petrol on to the carpet and set it alight at 3 am on September 11, 1990. Mr Michael Ozorio was not called on to reply on behalf of the victims' families. Reasons for the decision will be given later. The case will be sent back to the District Court to decide the amount of damages.
