The history of rivalry between the ICAC and Kevin Egan and Andrew Lam Ping-cheung can be traced to a number of cases, but there are two that stand out as potentially putting the parties at loggerheads. The first high-profile case involved Lisa Tung Lee-cheung, a former mainland cadre accused of cheating her business partner out of $3.3 million. Ms Tung was acquitted in January 1996 after a judge ruled the business partner had a grudge against the defendant. Mr Egan, representing the former official in the mainland Industrial and Business Management Commission, had argued that the business partner, the prime witness in the case, framed Ms Tung in retaliation for causing her father's arrest for allegedly misappropriating $46 million. Another showdown came several years later when former Miss Asia award winner and TV talk-show host Elsie Chan Yik-zee was arrested in 1999 on a charge connected with an alleged $515 million land fraud. She faced a joint count of conspiracy to defraud with her mother and two others. It was alleged they conspired with Macau legislator Tommy Chio Ho-cheong, also known as Chan Kai-kit, to defraud the Agricultural Bank of China in Guangdong and two firms owned by the bank by inflating the worth of a Mai Po land deal between May 1991 and March 1993. In defence, Mr Egan argued that Chan's presence during the business talks with the bank officials only amounted to her being a 'decoration'. Chan was acquitted in June 2002.
