This question is prompted by the story of Tommy Gregory Thompson who has just been released from nearly 10 years of incarceration for civil contempt (and starting 2 years for criminal contempt).
He claims he suffers from a rare form of chronic fatigue syndrome that has created problems with short-term memory, and does not know the answer to the questions. The government contends Thompson is refusing to cooperate and that there’s no connection between his ailment and his ability to answer to the question.
If this was a criminal trial I think the finder of fact would have to have no reasonable doubt that Thompson could answer the question before a custodial sentence could be applied. If this was a question of finding the result of a civil trial then the finder of fact would have to have only a greater than 50% chance that they are liable.
What level of certainty must a finder of fact in a civil case that someone deserves to be incarcerated for contempt in a civil proceeding?
