No they're not. JB needs to produce some evidence that undermines his conviction to the extent that 3 appeal court judges will take the view that had jurors heard it they may have returned a different verdict.
He’s already tried that, twice — and failed both times
In fact, not only did the appeal court reinforce the jury’s decision that Jeremy Bamber is guilty, but FURTHER evidence has come to light SINCE the original court case, that further proves his guilt.
At the original court hearing forensics established 13 out of a possible 20 markers which was enough to convince the court that the blood flake in the silencer could have only come from Sheila, as no-one else had those same markers .
In or around 2002 (I need to check) they retested that blood flake and found SEVENTEEN of Sheila’s blood markers, meaning it was a trillion to one that the blood was anyone else’s.
So if it DID ever get to appeal again, which it won’t, it would be thrown out again. And if there was ever a retrial, which again won’t happen imi, he will simply be found guilty again imo.
