LENGTHY argument is to begin in the High Court in January in the case of former Carrian Group boss George Tan Soon-gin, 62, who faces fraud and corruption charges. In a preliminary hearing yesterday, Mr Justice Stuart-Moore was told legal submissions were likely to last six weeks. A break would follow for lawyers to consider matters arising from the arguments. Tan's trial is expected to start by the middle of next year. The charges arise out of secret loans allegedly made by Bumiputra Malaysia Finance to the Carrian Group, which collapsed in 1983. He faces four charges of conspiracy to defraud, five of corruption and one of false accounting.
