RETIRED civil servant Harry Hui Kin-hong won as much as twice his yearly salary on horse-racing bets but could not recall his 'big wins', the District Court heard yesterday. Hui, who is accused of having funds and assets he cannot explain, claimed he could not recall his wins without referring to his records and he did not remember ever celebrating them. He says he won $1 million of his unexplained income gambling on horses and has pleaded not guilty to maintaining a standard of living above that commensurate with his earnings. Under cross-examination yesterday, the former buildings surveyor said he was a successful gambler who often struck it lucky, so he rarely differentiated his wins. 'Where some people have a gambling problem, you have a gambling gift - one year you were ahead of the game by more than double your annual salary,' prosecutor John McLanachan said. The Crown said he 'won big' on three occasions; $156,000 in April 1984, $325,000 in October 1984 and his 'Golden Month' in February-March 1989 in which he won about $500,000. But Hui maintained he could not recall celebrating the wins. A member of the Hong Kong Jockey Club since 1979 and an avid race gambler since 1968, Hui agreed with Mr McLanachan that his lucky streak began in 1984. 'Between 1968 and 1984 you were not winning very much, were you?' the prosecutor asked. Hui replied: 'I do not remember.' 'You have no recollection of this? You don't remember jumping in the air, telling your wife and your friends about the win?' the prosecutor asked. 'Of course, I would have been joyful, but without record everything would have faded from my memory,' Hui replied. Prosecutors say nearly $1.5 million in unexplained funds found its way into Hui's bank accounts between January 1988 and December 1990, sparking suspicions he was taking bribes. He claims his well-honed gambling technique of plotting his betting strategy in a diary before each race was behind most of the surplus. He claims another $400,000 was lent to him by his brother-in-law. Hui was freed from the District Court last December when Judge Muttrie ruled that the charge he faced under Section 10 (1) (a) of the Prevention of Bribery Ordinance contravened the Bill of Rights because it did not allow for the presumption of innocence. The appeal court overturned Judge Muttrie's ruling in April. Mr Justice Bokhary said the new law was an essential weapon against corruption. Hui joined the Buildings and Lands Department in 1965 and retired last year as senior estate surveyor or acting chief estate surveyor. He earned a net salary of $4,530,790 during his career and of that, $1,461,277 was earned during the three-year period in question. The trial before Judge Kilgour continues.
