Dear Winnie
Ko was poor. It was part of the written judgement. Unless the judge got it very wrong factually, but I rate that as unlikely or impossible. The fact is that we have a poor student buying gifts for her professor.
Even if it was infatuation love, there must be some SMS or email trial aka NBG. There was nothing. Even if the relationship was one-sided, there must be something he bought for her, even a fucking teddy bear and bunch of roses. There was nothing. On the balance sheet between the two, no one expects dollar to dollar parity, but there cannot be Professor Teh 100 Miss Ko Zero apart from the A.
She definitely denied it on stand and went against her witness statements. I can understand why, to protect her law degree and grades at any and all costs. However Prof Tehs statements were self incriminating which he did not managed to overturn. The judge chose to believe in the original CPIB statements for both. This might serve as a possible grounds of appeal as this decisions on this particular grounds are argued at the high court and not sub.
The "grade inflation." If there is an out for PT its in the marking. He pushed her if he did towards the higher end of the scale but still within the realms of grading possibles
The bottom line, he had to prove a relationship he did not, He was in a position to directly influence her grades unlikes NBG and PL. With that distinction between the two, the first became all important.

Ko wasn't poor. She could have refused but she took it on for whatever reason. She was in love with him. And he loves the sex. And he milked her. But that does not constitute corruption. She didn't ask for higher grades and he didn't offer or do it. They had a relationship of love and lust, love for Ko and lust for Tey.
