Prof Tey - Does silent means admission?

Prof Tey Tsun Hang, 41, arrived in court on 24 Aug 2012 (Thurs) afternoon with his lawyer for a pre-trial conference. Reacting differently from his previous encounters with reporters, Prof Tey refused to reply to the queries made by reporters. When constantly pushed for an answer if he had indeed had sex with his student, Darinne Ko Wen Hui, between May and July 2010, Prof Tey smiled but decline to comment further. Many may assumed that this would mean a silent admission as the answer should be simple and blunt if otherwise, nonetheless, I guess we will know in mid October 2012 when he is due to appear in court again. the trial is expected to last for 9 days.
