A student who has been expelled from his degree program for internet plagiarism is suing the university for having caught him too late. He claims that the school "should have spotted what he was doing and stopped him sooner."

It's a technique I've used since I started the course and I never dreamt it was a problem. I can see there is evidence that I have gone against the rules, but they've taken my money for three years and pulled me up the day before I finished.
