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.
