Former Kansas Attorney General Phill Kline has filed a federal lawsuit against the Kansas Supreme Court justices and others related to the suspension of his law license over his investigations of abortion providers.

His attorneys contend in a complaint filed Monday in U.S. District Court in Kansas that the court enhanced Kline’s punishment because of his “fervid beliefs” against abortion. The lawsuit also contends the court selectively applied rules governing attorney conduct.

The Kansas Supreme Court sanctioned Kline’s law license in October 2013. The court found that as attorney general and as Johnson County prosecutor, Kline misled judges and a Kansas City-area grand jury to further his investigations against a Wichita abortion doctor and an Overland Park Planned Parenthood clinic. The court didn’t immediately respond to an email seeking comment.
