If elected Judge, Duncan promises that he will fairly administer the Laws of the State of Montana. He feels that he is the best person for the seat not only because of the wide and varied experience he gained over the last 25 years practicing law, but because of his real life experience in agriculture, mining, and geology.
Duncan, in hearing cases, promises to be fair, reasonable and impartial. He will act with honesty and integrity, applying the facts to the law in a fair and consistent manner.
