Zacs-Master - //'there is a very great likelihood that further evidence was produced that caused a different outcome.'
'to say that Evans should not have been found guilty in the first place remains inaccurate.'
Eh? If that evidence had been produced at the first trial, maybe (quite possibly) Evans wouldn't have been found guilty, so how on earth can you make the second statement?
Quite simply - the evidence at the second trial was not produced at the first trial.
That is why Evans was found guilty the first time, and not guilty the second time.
Let me give you a simple illustration -
Mr Hughes, you have been found guilty of murdering the man who entered your home.
Mr Hughes, you have won the right to an appeal.
Mr Hughes, evidence not available at the first trial confirms that you did kill the intruder, but he was about to shoot you, and you believed your life was in danger, and acted in self defence. You are therefore not guilty of murder.
A more extreme scenario, but the valid point is evidence not heard in the first trial, but heard in the second makes for a different result.
