The quirk is that he had no choice but to sit through a trial by judge to have a jury trial. If there were the option in NC like in some states he would have probably opted for a trial by jury to begin with, which he would have been more likely to win. That is why NC has trial de novo which makes it as though the judge trial never happened. It is not a quirk or a loophole that the judges decision is vacated if you opt for a jury trial.
Also there is certainly no proof that she has been paid off. I am of the understanding that if he had done that it would be considered a crime. I would imagine if they had evidence they would bring charges. Im guessing they cant provide any evidence other than hearsay.
