Term limits

The Montana legislature is one of 15 state legislatures with term limits. Voters enacted the Montana Term Limits Act in 1992. That initiative said that Montana senators are subject to term limits of no more than two four-year terms, or a total of eight years.

The first year that the term limits enacted in 1992 impacted the ability of incumbents to run for office was in 2000.

Vacancies

If there is a vacancy in the senate, the Board of County Commissioners that represent the vacant seat must select a replacement. The Secretary of State must notify the Board of Commissioners and the county central committee of the political party that holds the vacant seat no later than seven days after the vacancy happened. The county central committee has 45 days after receiving notice from the Secretary of State to provide a list of candidates to the Board of County Commissioners. The board must select a replacement no later than 15 days after receiving the list of candidates. If the Senate is in session, the selection must be made no later than five days after receiving a candidate list. Any person selected to fill a Senate seat serves until the next scheduled general election.
