The seats of Montana Supreme Court Justices Laurie McKinnon and Jim Shea will be up for a nonpartisan election in November. Jim Shea is running uncontested while McKinnon is running in a race with Mike Black.
McKinnon was last elected in 2012 while Shea was appointed in 2014 and elected in 2016. Two of Montana’s supreme court justices, including Shea, were appointed by Democratic governors, one was appointed by a Republican governor, and the rest were elected.
The seven justices on the Montana Supreme Court are elected in nonpartisan elections for eight-year terms. The candidates compete in primaries where the top two contestants advance to the general election. Whenever a vacancy occurs, the governor appoints a replacement from a list produced by the Montana Judicial Nominating Commission. The appointee, if confirmed by the Montana Senate, then remains in the seat until the next general election after their appointment. At this time, the appointed justice must run for re-election as the incumbent in a nonpartisan election to complete the remainder of the unexpired term.
Across all types of state supreme court elections, incumbent justices running for re-election won 93% of the time from 2008-2019. Montana has not seen an incumbent supreme court justice lose an election during this same time frame.
