The prosecution of Tey was fishy. Why the NUS decided to report his violation of rules to CPIB? The NUS didn't even bother to investigate, just handed it over to CPIB.
Where is the proof that Ko got a higher grade because of sex and gifts? NUS could compile the data to show that. It didn't or couldn't?
I don't care a hoot about Tey but took interest in this case after his cross-examination showed how incompetent CPIB was and the unusual eagerness of NUS to take Tey down with a weak case.
