IANAL, but I assume lawyers are always looking for any precedent.
If someone claims someone else scammed them (in a civil or criminal case), they’re going to appeal to past similar cases. The civil case might even depend on the outcome of a criminal case against the same person. If they’re actually found not-guilty in a criminal case, then a civil case probably isn’t going to go anywhere. So if trump can convince a civil class action lawsuit to settle because it looks like they won’t win, then he can just pocket the difference.
All of this is my own conjecture as I see it, not to be considered factual.
Good example. Hard to say if any of this rational will ever apply, though. I just expect him to either ignore anything a court says, or push it to the supreme court where the president is above the law.
