Comment
[1] A judge is permitted to accept honoraria, stipends, fees, wages, salaries, royalties, or other compensation for speaking, teaching, writing, and other extrajudicial activities, provided the compensation is reasonable and commensurate with the task performed. The judge should be mindful, however, that judicial duties must take precedence over other activities. See Rule 2.1.
