On 1995 O.J. was found not guilty in the famous murder case. This was in criminal court and after that he was tried for the same thing in civil court - except this time it was called wrongful death rather than murder. He was found "responsible" and ordered to pay $33.5 million in damages. How is this not double jeopardy? After being tried and found not guilty he was tried for the exact same thing in a different court.
This source says:
The catch is that the second trial involved civil charges, not criminal charges. The penalties are different -- imprisonment or even death for guilt in the criminal charge of first degree murder, but only financial penalties for the civil charges of being found liable for a death.
Just because you call it a different name doesn't mean you aren't being tried for the same thing. If this is an actual loophole, doesn't it allow resourceful adversaries to lock their victims into court battles indefinitely?
