I don't think so, but I think that could be handled on the side of the court, not the side of the exchange. It could certainly be illegal, or at least a disbarrable offense, for a judge to use his or her knowledge for personal gain. Likewise, many of the most flagrant examples of insider trading could be covered under trade secret or contract law, like a CEO shorting his or her company then purposefully sabotaging it.
That sounds like a question for a professional ethics board. I would assume a judge caught doing that would be sacked, disbarred, and publicly shamed, even if everything he did was strictly legal.
And how does the incentive to lie to other traders apply only to insider trading? It seems like that would always apply to all trading.
