An academic and senior lecturer at the University of Greenwich has lost a High Court fight after she accused other academics of plagiarism, among other serious claims.

Caroline Ukoumunne had made a series of complaints including racial harassment, sex discrimination, bullying, copyright infringement and professional negligence, suing a number of other academics and Birmingham University.

Ms Ukoumunne, a lecturer at Manchester Met University and the University of Greenwich's education and community studies department, made complaints on work she did when a PhD student more than a decade ago.

But a High Court judge on Wednesday ruled that all these claims should be struck out.

Recorder Amanda Michaels said Ms Ukoumunne had provided "no evidence" of copying or reproduction of a substantial part of any of her works.

The judge had analysed the latest stage of the case at a High Court hearing in London in December.

Ms Ukoumunne, who had produced a PhD thesis called Black Activism In Education: Lessons from the Unheard, has also made claims relating to breach of confidence and breach of contract.

The judge did not strike out those claims, but Birmingham University bosses dispute them.
