In 1996, questions were raised about the work of Paula Lannas, the defence pathologist. During a trial at the Old Bailey in June 1998, Lannas testified that bruising on the neck of a 16-month-old child "resulted from strangulation by the mother's boyfriend." The defendant was acquitted when forensic pathologist Iain West testified that the post mortem examination had been so "" that the bruising may have been inflicted by Lannas, and the prosecution informed the jury that her conclusions were "suspect" and could not be relied on as evidence. In May 2000, two men had their convictions for manslaughter quashed when it was disclosed that Lannas had testified at their trial that the victim had been killed by a stab wound and had no other injuries. Subsequent examination found a potentially fatal skull fracture. A 2001 disciplinary tribunal alleged that Lannas's pathology work "consistently fell substantially short" of expected standards and there were "substantive deficiencies" in "her technical approach and medical knowledge."
