The sex-for-grades trial was on Monday adjourned for two weeks for law professor Tey Tsun Hang to undergo an examination at the Institute of Mental Health.
The defence applied for the tests, which will determine if Tey, who turned 42 on Monday, is fit to stand trial. Tey appeared on the dock looking weary, wearing a cardigan and a scarf. He faces six charges of corruptly obtaining gifts and sex from a former student.
Dr Bharat Seluja, an IMH forensic psychiatrist, had on Friday written a letter to the court indicating that an assessment would require four weeks. The Attorney-General Chambers then asked to expedite the matter. Chief District Judge Tan Siong Thye decided that the trial will resume on May 6, or on any date when the report is ready, whichever is earlier.
Earlier, the judge asked for an update into Tey's condition. Defense counsel Peter Low later said: "He's fatigued - to use his words - physically and mentally, and he's under medication, and he says he's got difficulty in answering questions. He will face difficulties in answering questions and in the general conduct of the defence."
