Top criminal barrister Kevin Egan and prominent solicitor Andrew Lam Ping-cheung will enter pleas in the District Court on April 1 to charges involving conspiracy to pervert the course of justice. Principle Magistrate Ian Candy transferred the case after an application yesterday by government prosecutor Alex Lee in Eastern Court. Their bail was continued. Against Mr Lee's objection, Mr Candy also temporarily removed Lam's travel restrictions and returned his home-visit permit until next month's hearing. Lam's defence counsel, Graham Harris, told the court his client needed to travel to Shanghai for business purposes. Mr Lee objected to the application in view of the seriousness of the case. He also tried to persuade the court to restrict the number of Lam's visits to the mainland. But Mr Candy said: 'I am not restricting the number of times of his travel. He knows his profession and he knows the rule.' He ordered Lam to notify the ICAC, which brought the charges, 24 hours before his departure and to leave his mainland contacts. Lam, 53, is on $200,000 bail, while Egan, 58, is on $50,000 cash bail and a $50,000 surety to be paid by a third party should he abscond. The charges relate to an investigation into stock manipulation of publicly listed Semtech International Holdings. Also charged was former Semtech chairman Derek Wong Chong-kwong, 37, and Mandy Chui Man-si, 25, a company director. The four were arrested on conspiracy charges by ICAC investigators at their homes, at 6am on March 3. All are on bail without having entered a plea. The ICAC arrested Wong last July over alleged manipulation of Semtech's stock price. The charges state the four conspired to pervert the course of justice by giving information to journalists to publicise the assistance being given by a woman to an ICAC inquiry. They also allegedly made false claims that she was being detained against her will. Egan is also charged with disclosing information about the witness' identity to a reporter.
