A key chapter of Hong Kong's corporate history will come under the spotlight from the end of next month when the trial of former top broker Arthur Lai Cheuk-kwan and four others on fraud charges is scheduled to begin. Lai, a former chairman of Standard Chartered Bank's securities business, and his co-accused are charged with fraud in relation to Tomson Pacific's 1990 purchase of a 34.5 per cent stake in Bond Corp International. Legal sources said the trial was scheduled to begin on June 1, with proceedings expected to take several months. Lai, his brother Raymond Lai Chik-fan, former movie actress Jade Hsu Jye, former Standard Chartered securities staff member Peter Mou Chi-luen and former Tomson Pacific executive Tong Cun-lin are each charged with one count of conspiracy to defraud the Securities and Futures Commission. Arthur Lai is also charged with accepting a A$2 million (about HK$10 million) advantage from Bond Corp for introducing Bond Holdings to Tomson Pacific and his involvement in the placement of an additional 31.35 per cent of Bond Corp shares to other parties. He is also charged with accepting a HK$26.4 million introduction fee from Tong and former Tomson executive Chang Jen-chiang in relation to the Bond deal. Raymond Lai and Peter Mou are charged with aiding and abetting Arthur Lai's acceptance of the HK$26.4 million and A$2 million fees. Tong is charged with offering the HK$26.4 million fee. The prosecution will allege that between January 1, 1990 and June 30, 1991, the accused conspired with Mr Chang to defraud the SFC, its Committee on Takeovers and Mergers and its then-chairman Ermanno Pascutto and staff. The accused were charged in August 1996 after a two-year Commercial Crime Bureau investigation. The High Court trial will be heard by Mr Justice Keith.
