The Minnesota Supreme Court primary may be the most important election nobody's heard of
A quick primer: The Minnesota Supreme Courts seven justices make up the states court of last resort, handling appeals from Minnesotas lower courts and big-picture legal questions, such as statutory issues and questions dealing with the Minnesota Constitution. It also helps administer lower Minnesota courts.
Justices are elected to six-year terms and are required to retire when they turn 70. If they vacate their seat midterm which happens most of the time, often because of the age limit the governor may appoint a replacement. That replacement must face election to keep the seat.
While the Minnesota Supreme Courts rulings can affect all Minnesotans, most Minnesotans never come into direct contact with it: You might remember it from the state Senate recount in 2008 and the gubernatorial recount in 2010 the Minnesota Supreme Court made rulings in those processes.
