A Catholic school student who suffered serious mental health problems after years of bullying by the "popular group" has had her damages payout increased despite efforts by the school to have the matter thrown out of court.

Jazmine Oyston successfully sued St Patrick's College at Campbelltown for negligence in 2011 after telling the court she had been called "slut", "bitch", "dog" and "pimple face" by students and was physically attacked in the corridors.

But the school launched an appeal earlier this year, claiming she should not receive compensation because she repeatedly failed to inform the school about what was happening.
