The recent debate in this thread about statistics is irrelevant. The issue is that the world expert in the use of statistics in such cases, Professor Richard Gill, has condemned the statistical analysis which was presented (condemned being a mild version of his opinion in this case). And he should know since he was the author of the guidelines from the Royal Statistical Society for the use of statistics in medical cases in court.
The real issue in this case is that, one by one, the 'experts' who testified in the trial have been shown to be incompetent, under investigation for professional standards or testifying beyond their area of expertise. It is impossible to sustain the conviction when the entire case has been undermined and the only question is whether the Court of Appeal should order a retrial in setting aside the verdict.
