A doctor whose application to have his licence restored was rejected due to a 'particularly serious' criminal conviction is taking the Medical Council to court. Lawyers for David Chow Siu-shek, 50, accuse the council of being 'manifestly unreasonable' in prolonging his removal 'indefinitely, if not permanently'. They filed a writ in the High Court yesterday challenging the council's February 3 decision to reject Mr Chow's application to practise again in the SAR, calling it irrational. Mr Chow was jailed for two years in November 1990 for conspiring to defraud the School Medical Services Board out of $18.7 million. In 1995 he was fined $57,000 for failing to keep a proper register of dangerous drugs. He was struck off in 1994 for three years over the fraud plot conviction. In September, Mr Chow applied to the Medical Council to be allowed to practise again in the SAR. It was the first time in the council's 40-year history that the board had rejected an application from a struck-off doctor to restore his licence.
