Rule 21-312 Compensation for extrajudicial activities.

Judges can get paid for outside activities, like teaching a class or writing a book, as long as this outside work fits within what the Code of Judicial Conduct and other laws allow. The key limit is this: the payment can't make a reasonable person think the judge's independence, honesty, or fairness is compromised. If accepting money for an activity would make people doubt the judge can be neutral on the bench, the judge should turn it down.

Judges also can't take on other paid work that gets in the way of their judicial duties. If a judge has a full-time judicial position, that job comes first. The judge must actually put in the hours their judicial role requires, and they can't try to do outside paid work at the same time they're supposed to be working as a judge. In other words, a judge can't double-book their time, doing paid outside work during hours they owe to their court job.
