Now "balance of probability" in a civil case is another matter - I could be persuaded that it might be good enough for that but not in a criminal case.

Well as I say I would suspect the DNA evidence is probably accurate -but I would have to question why it was that having identified this person the Police were unable to turn up any other corroberating evidence at all.
Beyond reasonable doubt is a high hurdle.
However this is only my personal opinion and there are defined procedures under hich DNA evidence is deemed acceptable so appealing against that is unlikely to be successful. Effectively you have to appeal that the procedures were not correctly followed. Samples mis handled etc. This was the basis on which the OJ Simpson DNA evidence was famously attacked
