To appeal he will either have to come up with the cash that will be tied up for the duration of the appeals process or get a surety bond. Can he afford either?
He’s previously claimed to have 400-some million in cash available. Between this and the Carroll judgment, he would need all of that and more. He or somebody else could post a bond, but they’d be making what amounts to a half billion dollar+ bet that he would win on appeal. I don’t know that anyone else would be willing to step up to do that for him.
