The Court of Appeal yesterday ordered the retrial of a drug trafficking case after a judge was found to have delivered an unbalanced summary to the jury. Jailed Chan Kwok-wah is to face a new trial for trafficking in 'ice' because his conviction was unsafe and unsatisfactory, the court ruled. Chan was jailed last July for 15.5 years by Mr Recorder Ching Y. Wong, SC, in the Court of First Instance after being found guilty of trafficking in 404.5 grams of ice. A recorder is a lawyer sitting as a part-time judge. In yesterday's written judgment, Mr Justice Gareth Lugar-Mawson said the court was concerned about the directions given to the jury on various elements of the trafficking offence and the tenor of the trial judge's summing up. Mr Justice Lugar-Mawson found Mr Recorder Wong had delivered a biased summary of the defence case by devoting nine pages to pointing out weaknesses, effectively demolishing it. 'We were of the view that this part of the summing up, and it is a substantial part, reads as if it were a closing speech for the prosecution,' Mr Justice Lugar-Mawson said. 'Comments may be so weighted against the defendant as to leave the jury little choice other than to comply with what are obviously the judge's views or wishes.' The appeal judge noted that the demolition of the defence case was delivered just before the jury retired to consider its verdict and might well have left members with the view they should comply with Mr Recorder Wong's adverse views of the defence case. The appeal court also ruled Mr Recorder Wong had given an incorrect definition of trafficking in dangerous drugs to the jury. Mr Justice Lugar-Mawson, sitting with Mr Justice Simon Mayo and Mr Justice Frank Stock, was of the view that the error had influenced the outcome of the case.
