SOLICITOR Oscar Lai Ka-to, who was sentenced to seven years' jail for bribing disgraced government lawyer Warwick Reid to fix prosecutions, yesterday launched his appeal against conviction and sentence. Lai's London QC, Richard Ferguson, submitted that the trial judge's summing-up to the jury was confused, confusing and unbalanced. He said Mr Justice Saied failed to remind the jury of the defence case and although he reviewed the evidence in chief of main prosecution witness Reid at length and in some detail, he failed to deal adequately with what Reid said in cross-examination. Mr Ferguson also said the judge failed to give appropriate warnings to the jury on how to deal with evidence from alleged accomplice Reid. The trial in 1992 lasted 41/2 months and pre-trial arguments had taken four months. Businessman Lee Hoi-kwong, 51, is also appealing against conviction and his seven-year term for one offence. Co-defendant, barrister Eddie Soh Chee-kong, 51, withdrew his appeal against conviction last year. Mr Ferguson said the judge said the defence case was based on an attack on the credibility of Reid. But Lai had another line of defence which the judge did not put to the jury. It was that Soh had deceived both Lai and Reid so that, even if Reid were telling the truth, there was still not enough evidence to convict Lai. Mr Ferguson said the judge, whose summing up lasted three days, had dealt at length - probably in too much detail - with the evidence of each witness. But he had failed to explain to the jury which issues the various parts of evidence were dealing with. As there were a total of 15 counts, Mr Ferguson said it was essential the jury should be directed to the evidence on each one. He added that the summing-up was delivered at breakneck speed, so that even counsel did not pick up two major and two minor mistakes by the judge. The Crown is cross-appealing, asking the court to increase the sentences of 57-year-old Lai - if his appeal fails - and Soh. They were convicted of five and seven corruption offences respectively. Reid, also serving a seven-year jail sentence for one corruption offence, is due for release in November.
