Civil cases are judged based on the proponderance of the evidence meaning they have to be swayed just beyond 50.000001% to render a verdict in the favor of that side
Criminally, a jury must prove all culpability in every aspect of the charge(s) beyond a reasonable doubt, if the prosecution can not prove beyond a reasonable doubt (95%) then they have no case.
this is what is different in state to state... 8/12 people...7/12 or 11/12 maybe even 12/12
at least, that's how it works in NJ
