Mont. Code Ann. § 2-2-101

The purpose of this part is to set forth a code of ethics prohibiting conflict between public duty and private interest as required by the constitution of Montana. This code recognizes distinctions between judges, legislators, judicial officers, other officers and employees of state government, and officers and employees of local government and prescribes some standards of conduct common to all categories and some standards of conduct adapted to each category. The provisions of this part recognize that some actions are conflicts per se between public duty and private interest while other actions may or may not pose such conflicts depending upon the surrounding circumstances.
