Former Kansas Attorney General Phill Kline is asking the U.S. Supreme Court to review the Kansas Supreme Court’s indefinite suspension of his law license.

In a filing Monday, Kline’s lawyers contend the Kansas court selectively applied rules governing attorney conduct in deciding the ethics case arising from his investigations of abortion providers.

The Kansas Supreme Court sanctioned Kline’s law license in October 2013. The court found that as attorney general and later as Johnson County prosecutor, Kline repeatedly misled or allowed subordinates to mislead others, including a Kansas City-area grand jury, to further his investigations.
