Not on a crime. You cannot try a man for the same crime twice without new evidence. This "evidence" is not really evidence is it? All you have is speculation. If it was at a legislative level, THEN you could appeal it, or if a man is guilty he could appeal for his innocence. Not if a man is innocent. This isn't Italy. However, I would also point out that this evidence was used in the FIRST accusation, but never revealed, as Ginger pointed out, therefore also excluding it from being NEW evidence.
I think Saren Arterius of Mass Effect said it best when he asked, "Are we allowing dreams into evidence, now? How can I defend my innocence against this kind of testimony?" To which the reply came "I agree. Our judgments must be based on facts and evidence, not wild imaginings and reckless speculation." It is indeed a considerably funny thing, for KillerZebra, how long this forum was open and yet he comes riding in when it has closed and Zoma jumps back up, salutes, and says, "I am ready to reoffer up my evidence!" after not apologizing to the one he accused or taking back his accusation. A promise broken which calls into question moral integrity and questionable motives. I call into question the motives for this line of thinking. Seems like nothing more than a corruption of opinion and justice to me.
