AFTER an eight-hour deliberation, the High Court jury trying Legco member Gilbert Leung Kam-ho failed to reach a verdict and the jurors were told to rest for the night and continue today. Leung, 40, was allowed bail and told by Mr Justice Keith to return in the morning and await the verdict on the bribery charges. At 8 pm when the jury was called in by the judge and asked if there was any prospect of a verdict in half-an-hour, the foreman said no, and added that the jurors were too tired to continue. Earlier in his three-hour summing up, Mr Justice Keith told the jury that the existence or otherwise of the practice of ''tea money'' was not a defence to the charge or justification for what a defendant had done. The case had been delayed for a few days last week after Leung collapsed at the funeral of his colleague, Stephen Cheong Kam-chuen, and was admitted to hospital. Leung was discharged on Saturday. Leung who faces eight charges, three of them alternatives, was present in court yesterday to hear the summing up. He seemed a little slimmer and smiled when the judge said he was glad to see him in court and hoped he had recovered. Several of Leung's supporters and his family were present in court, as well as a large group of pressmen and photographers. At 12.15 pm, on completion of the summing up, the judge told the three women and four men on the jury panel that orders for lunch would be taken by the usher so they would not be disturbed later. In his summing up, the judge told the jury that a defendant had a right not to give evidence in his defence even though it would leave nothing to explain the Crown's allegations. Leung who had been on trial for 20 days called witnesses to testify on his good character and public service, but did not give evidence to refute the charges. If convicted, he faces a maximum of seven years on each count. In a rare move, the judge gave the jury written directions on the eight charges, listing questions they should answer in their deliberations before reaching a verdict. Earlier the judge warned the jury about the evidence of three main witnesses - District Board members Lau Hon-kit and Ko Kim-chi, and Leung's unofficial election agent, Wai Hon-leung. The judge pointed out that these witnesses were accomplices with Leung on six of the eight charges he faced. He said it was dangerous to convict Leung based on their evidence alone on the six charges unless it was corroborated by other witnesses. But in this case there was evidence capable of independently confirming what the witnesses had said in implicating Leung, Mr Justice Keith said. The eight charges arose out of Leung's bid to get elected in the Regional Council functional constituency elections to select a representative to sit in Legco. Four candidates were vying for the seat. There are 36 Regional Councillors and each was allowed to cast four votes giving a preference order of the candidates. At the elections on September 12, 1991, Leung defeated the other candidates in a close contest.
