A bitter row between the supervisor of a prestigious local school group and a well-known philanthropic alumnus has escalated into a full-scale legal battle in which top officials including Hong Kong’s chief secretary were named as parties to be taken to court. In one of the five writs filed at the High Court on Friday, businessman Koo Ming-kown, known as Hong Kong’s “electronics king”, accused chief secretary Carrie Lam Cheng Yuet-ngor of failing to take concrete steps to investigate the conduct of Hopkins Chan Chi-mong. Chan is a Justice of Peace appointed by the government and supervisor of Hong Kong’s Pui Ching Middle School and the Hong Kong Pui Ching Primary School. Koo claimed that Chan, who also held directorship in two Hong Kong-listed companies, had made false declarations of his academic qualifications. In his writs, Koo questioned whether Chan was worthy of the various positions and honours. “[The chief secretary] should only appoint a person to be Justice of Peace if she considers such person to be fit and proper,” one of the court documents said. Koo requested Chan’s honour and appointments to statutory bodies be revoked. In a separate writ against education secretary Eddie Ng Hak-kim, Koo questioned if Chan was fit to supervise the schools, and asked the court to revoke those appointments also. Koo filed writs against the two listed companies for not disclosing details of the academic qualifications, and the president of the Hong Kong Baptist Convention, which runs the schools. In a statement, the convention said it was dealing with the matter.
