Businessman Bobby Choi will be disciplined for citing his Liberal Party membership in his lawsuit, the party leader said yesterday. Mr Choi was risking his membership by introducing himself as the 'former central committee member and vice-chairman of Liberal Party in Tuen Mun District' in a writ against Penglai Public Security Bureau. Liberal Party chairman and provisional legislator Allen Lee Peng-fei yesterday declined to offer personal or political help to Mr Choi. Mr Lee, a former colleague and long-time acquaintance of Mr Choi, said he would do nothing to help in the businessman's 'private dispute' with the bureau. 'I can't help him because it is a personal dispute. It is virtually impossible for the party to get involved,' Mr Lee said. 'He will be disciplined if he uses the name of the party to deal with his dispute.' Mr Choi insists he has not used his party membership in dealing with the bureau, but a copy of his writ describes him as a 'former Liberal Party member'. Mr Choi and his 28-year-old son, Choi Wai-yip, of Siu Shan Court, Tuen Mun, are both members of the 520-strong Liberal Party.
