IT is a New Territories tradition for the winner of an election to pay $20,000 to $30,000 ''tea'' money to the voter to show respect, the High Court heard yesterday. Politician Mr Lau Hon-kit said he told Regional Councillor Mr Fung Pak-tai that if he voted for Gilbert Leung Kam-ho in the Legco election, he would get that amount of money. Mr Lau, when questioned by Mr Michael McMahon for the Crown, said that according to the tradition in the New Territories, that was the common amount promised. Mr Lau, a Sha Tin District Board member, and Mr Fung, one of the 36 Regional Councillors who cast their votes to elect a representative to Legco, were ''rewarded'' with $50,000 after Leung won his seat in September 1991. Mr Lau, giving evidence under immunity at the bribery trial of Leung, told Mr Justice Keith and the jury that he was assured by Leung that if he succeeded in the election he would not be mean to him and Mr Fung. After the election, Mr Lau said Leung came to his Sha Tin office and told him that Mr Fung had only named him as second choice. It was claimed that Leung said it did not matter since he had won. Mr Lau was handed a cheque of $50,000 by Leung. The payee was left blank. Mr Lau subsequently cashed it. He claimed that he gave $20,000 of the money as a loan to his clansman and waited for an opportunity to give the remaining $30,000 to Mr Fung. The witness said that one day, Mr Fung came to his office and asked in a low voice whether Leung had left him anything. He said yes but he could not hand the money over as it was at his home. About a month later while he was giving Mr Fung a lift in his car, he handed him an envelope containing the $30,000. When Mr Fung tried to open the envelope, he was dissuaded by Mr Lau who told him to telephone him if he wanted to talk. Under cross-examination by Mr Cheng Huan QC, Mr Lau said he was aware that Mr Fung was soliciting donations for some affairs in Cheung Chau but was unaware if he had asked Leung for a donation. Leung, 38, has denied seven counts of offering money to two Regional Councillors and two other men in return for procuring his election to the Legislative Council. He has also pleaded not guilty to incurring election expenses in excess of the limit of $50,000. Leung is also alleged to have offered $100,000 to Regional Councillor, Mr Cheung Hon-chung. Mr Lau said he arranged for Leung to meet Mr Fung at a restaurant so he could get his vote. Mr Lau was later asked by Leung to convince Mr Fung to vote for him. Earlier Mr Wai Hon-leung, a Justice of the Peace who was also testifying under immunity, said he was told by Leung that he had offered ''something'' to Mr Fung who rejected it. He denied a suggestion from defence counsel that he wanted to be Leung's political adviser, adding that the suggestion came from Leung himself. The hearing continues.
