In October 2004, Sarah Forsyth claimed that she had been dismissed unfairly by Eton College and had been bullied by senior staff. She also claimed she was instructed to do some of Prince Harry's coursework to enable him to pass AS Art. As evidence, Forsyth provided secretly recorded conversations with both Prince Harry and her Head of Department, Ian Burke. An employment tribunal in July 2005 found that she had been unfairly dismissed and criticised Burke for bullying her and for repeatedly changing his story. It also criticised the school for failing to produce its capability procedures and criticised the Head Master for not reviewing the case independently.
