Another Hong Kong Medical Association leader has said he is prepared to be expelled from the Medical Council after he refused to follow the new roster system to participate in disciplinary hearings. Choi Kin, who was defeated by Felice Lieh Mak in the election for council chairman in March, said the roster system was unfair and he was considering seeking a judicial review. On Thursday, the president of the association, Tse Hung-hing, was expelled from the council for making a false declaration. Professor Lieh Mak said yesterday Dr Tse's expulsion was done in accordance with the law. Regarding Dr Choi's case, she said the council could expel any member who failed to fulfil his duty. The council introduced the roster system last month following advice by the Independent Commission Against Corruption. The disciplinary hearing panel members are told about the facts of the case before the hearing. To avoid possible conflicts of interest and corruption, panel members would be assigned to hear a case according to a roster. Members who cannot attend a hearing need to find a replacement. Dr Choi said he had told Professor Lieh Mak that he refused to take the roster duty. 'I am a dutiful member and I have attended more than 90 hearings in the past years, I don't like the idea of restricting which hearings I can attend,' he said. 'The roster system aims to make sure some members with low attendances share the workload. However, it deprives me of my right to attend other hearings I want to go to. 'I am prepared to be expelled from the council. I am considering a judicial review.' Dr Choi said the expulsion of Dr Tse from the council was damaging to the association's reputation. Dr Tse was expelled over a false declaration he made when running for the post of chairman of the council's ethics committee. He failed to mention a HK$1,000 fine for careless driving on his nomination form - although he had earlier advised the council of it. Professor Lieh Mak said yesterday that most members had agreed to the roster system. 'It can distribute the workload more fairly among members. It is a fair system.' She said the council would decide later what action would be taken against Dr Choi if he refused to follow the roster system. 'Anyone is free to seek a judicial review ... under the law, the council expels a member who fails to fulfil his duty,' she added. Professor Lieh Mak said the council had decided to report Dr Tse's case to the police and expel him because making false declarations was a serious offence. 'The council needed to act to uphold professionalism and our credibility. Our doctors' registration and education accreditations all rely on declarations. We have to be fair to everyone,' she said. 'It is nothing personal [to Dr Tse] and we are not acting against the Medical Association.'
