If it was available at trial like you say then it is inadmissible for grounds of appeal at 89 and 02 as you already know.
The only way round that is to either argue "cleverest of the clever" was inept and thus fair trial impossible or wait until our legal system takes a more inquisitorial approach and widen the criteria for appeals (which it is slowly doing)
David please stop trying to make out you're some legal hot shot when you're anything but.
You misunderstand "fresh evidence". If new tests on a different theme produce different results this equates to fresh evidence.
The "cleverest of the clever" was clearly incompetent and negligent in the same way the one who can "secure a result like no others" was. The worrying thing is how many other innocent people have gone down and how many guilty got off if/when they were prosecuting?
This is my point about poor ideas and decisions emanating from homogenous groups. MT QC making the fatal mistake of not challenging his peers: "cleverest of the clever", Ewan Smith et al.
