Canto-pop idol Nicholas Tse Ting-fung may serve a prison term even if he completes his community service order, Director of Public Prosecutions Grenville Cross insisted yesterday. He said the Department of Justice was considering appealing against Magistrate Alan Wyeth's decision on Monday not to increase Tse's sentence for switching drivers after crashing his Ferrari in March. If it did, Mr Cross said, there was a legal precedent in which a defendant who completed community service went on to serve a subsequent jail term. Mr Cross' comments came after the chairman of the Law Society's criminal law and procedure committee, Andrew Lam Ping-cheung, said it was unlikely the star would serve a second sentence after finishing 240 hours of community service. Tse, 22, received his community service order for conspiring to pervert the course of justice after the crash. The sentence was greeted with outrage as the driver who took the blame for the crash was jailed for four months, while the policeman who aided the conspiracy was jailed for six months. In a letter to the South China Morning Post, Mr Cross said: 'The court [of appeal in a 1998 case] indicated that even if an offender has completed his community service . . . he may still expect to be imprisoned if his offence is such as to warrant imprisonment.' Mr Cross defended the Department of Justice's decision to first ask the magistrate to review his sentence rather than go straight to the Court of Appeal. 'A review . . . to the Court of Appeal takes far more time,' he said.
