SINGAPORE - The verdict for the sex-for-grades trial is expected to be made known on May 28, it was announced in court today (May 14), where lawyers made their closing submissions for the trial. National University of Singapore (NUS) law professor Tey Tsun Hang, 42, has been charged with six counts of obtaining gratification in the form of sex and gifts from his former student, Ms Darinne Ko, in exchange for better grades between May and July 2010. In Mr Low's closing submissions today, he said that during the time of the alleged offences, Tey and Ko were in an "intimate" relationship.For example, one of the alleged offences was that Ko had given Tey an iPod. Mr Low said that the iPod which was given to Tey "sometime in June (2010)" was "personal" for the pair and contained "love songs" which they listened to. Mr Low also urged Chief District Judge Tan Siong Thye - who is presiding the case - to dismiss the application to impeach Ko's statements which were given the court. During the trial, the Prosecution had seek to impeach Ko's statement in court as it differed from what was recorded at the Corrupt Practices Investigations Bureau (CPIB). Mr Low said that the conditions Ko made the statement to the CPIB were "unfavourable". For example, she had only three hours of sleep on the day she was hauled back to CPIB. Deputy Public Prosecutor Andre Jumabhoy submitted in his closing submissions that Tey - who conducted his own defence during the trial - suggested that he and Ko had a "mutually loving relationship". However, he added that there was a "vast amount of evidence which was not challenged" in relations to the charges by the defence. For example, one of the alleged offences was that Ko had bought a tailor-made shirt for Tey. Tey claimed that there was a discussion between him and Ko in a car on the way to the tailor to make a shirt for him. However, Ko claimed that there was no such discussion between them. If convicted, Tey could be jailed up to five years and fined S$100, 000 on each charge.
