I am curious why you think this? Or how you think it's possible? Jeopardy! has judges who are sitting in front of the audience. If Trebek is unsure of an answer he consults them (you can tell when he does this cause he'll look off to stage-right for a tick, usually holding his pencil in their direction). If he gives credit for a question that he should have or shouldn't have, they correct him during the commercial break and adjust the score after the break (anybody who's watched the show has seen this).
