A troubled High Court trial which twice collapsed because of blunders by prosecutors ended last night with three of the four defendants cleared of rape. The jury returned its verdict after considering the evidence for more than 11 hours. At 9.45 pm, Deputy Judge Pang Kin-kee told the jury they should stop their deliberations and spend the night at accommodation provided in the court building. The foreman then said the jury had reached verdicts. Chan Chi-wai, 17, Chong Lee-yung, 22, and Sin Wai-kin, 18, were cleared of raping a 22-year-old club hostess. Chong Lee-fung, 23, was found guilty of rape. All four were convicted of stealing from the woman. They will be sentenced today. The trial had collapsed twice in the space of three days, with the jury being discharged on each occasion, because of prejudicial material introduced by prosecutor Joseph To. This came within eight days of two other trials also being halted because of blunders by prosecution counsel. The Attorney-General, Jeremy Mathews, faced a storm of protest as lawyers claimed policies pursued by the Legal Department were to blame for putting lawyers into serious trials which they do not have the experience to handle. An internal inquiry has been launched but the results might not be made public, said Director of Public Prosecutions Peter Nguyen QC. The Legal Department said it stood by the decision to allow Mr To to prosecute the case. After the second trial collapsed, a 'heavyweight' prosecutor, Wayne Moultrie, who has 20 years' experience, was sent to help Mr To. However, the case was adjourned again over the introduction of new evidence. When the case finally began, a further problem arose when the prosecution was forced to withdraw from the case a magistrate's notes which were found to be inaccurate. But this time the judge ruled the case must continue.
