TOPEKA, Kan. (AP) — Caleb Stegall is preparing to join the Kansas Supreme Court after serving as a judge on a lower court and as a top aide to Governor Sam Brownback. The Supreme Court was having a special session Friday for Stegall's swearing in. Brownback elevated the 43-year-old Stegall to state's highest court in August after naming him to the Kansas Court of Appeals last year. Previously, Stegall served as Brownback's chief counsel. Before joining the administration in January 2011, Stegall was Jefferson County's elected prosecutor for two years. It is the conservative Republican governor's first appointment to the seven-member Supreme Court. Stegall will replace former Justice Nancy Moritz. President Barack Obama appointed her to the federal appeals court for Kansas and five other western and Plains states.
