The Kansas Supreme Court Nominating Commission is made up of 9 members responsible for recommending qualified individuals to the court. They review applications, hold public interviews of the applicants, and then send three recommendations to the Kansas Governor. The Governor then chooses the final candidate.
After one year new justices are up for a retention vote, then after that every six years they are up for retention. No Kansas Supreme Court justices have ever been voted out. This makes them a powerful group with no ramification for their actions.
