Administrative Rules Services

The Montana Secretary of State’s Administrative Rules Services publishes the administrative rules promulgated by state agencies. Administrative rules are developed under a process outlined in the Montana Administrative Procedure Act. That process requires state agencies to provide notice to the public when they wish to adopt, amend or repeal administrative rules. The notices are compiled in the Montana Administrative Register (MAR). Once adopted, administrative rules are published in the Administrative Rules of Montana (ARM) and have the force of law.
