Six will replace Paul Morrison, who will step down Jan. 31 in the wake of a sex and ethics scandal.

Six, the son of retired Kansas Supreme Court Justice Fred Six, grew up in Lawrence and clerked for U.S. Court of Appeals Judge Deanell Tacha.

In 2005, Six was appointed to the bench by Sebelius. Before being named a judge, Six was a plaintiff’s attorney in the firm of Shamberg, Johnson & Bergman in Kansas City, Mo.

Morrison, the current attorney general, has acknowledged having an extramarital affair with Linda Carter, the former director of administration for the Johnson County District Attorney’s Office. Before winning election in 2006, Morrison was the Johnson County district attorney and Carter’s supervisor.

Carter also has accused Morrison of sexual harassment and professional misconduct, allegations Morrison has denied.
