A formal complaint has been lodged against the judge who presided over the murder trial of British businessman Shrien Dewani in South Africa last year.
The Higher Education Transformation Network - a group of academics and lawyers - accused Judge Jeanette Traverso of "gross judicial bias and misconduct" after she dismissed claims Mr Dewani organised the murder of his wife Anni while on their honeymoon in Cape Town in 2010.
The judge called a halt to the trial in December, two months into the hearing, after an application from the 34-year-old's lawyers that the prosecution case was flawed.
HETN chairman Lucky Thekisho said: "Article five of the Judicial Code of Ethics requires judges to act honourably not only in the discharge of official duties but to act honourably and in a manner befitting judicial office in a professional manner that enhances the public trust in or respect for the judiciary and the judicial system."
Lawyer Mr Thekisho urged South African judicial authorities to suspend Judge Traverso pending an investigation.
Ashok Hindocha, Anni Dewani's uncle, said: "We agree that Anni did not get a fair trial.
"The case was not fully heard, she (judge Traverso) should have let Shrien take the stand."
