The state Supreme Court indefinitely suspended the law license of former Attorney General Phill Kline on Friday after allegations of ethical misconduct during his investigation of abortion providers. The court unanimously agreed with a state disciplinary panel that Mr. Kline, a Republican, repeatedly misled or allowed subordinates to mislead others, including a Kansas City-area grand jury, to further his investigations. His lawyer, Tom Condit, said Mr. Kline insisted that he never intentionally lied or misled others in pursuit of his case. In 2007, Mr. Kline filed 107 criminal charges against a Planned Parenthood clinic in the Kansas City suburbs, accusing it of performing illegal abortions and falsifying records. The last of those charges were dropped in August 2012. He also pursued misdemeanor criminal charges against Dr. George Tiller because of late-term abortions performed at his Wichita clinic. The case was dismissed for jurisdictional reasons. The justices said Mr. Kline committed “significant and numerous” violations while pursuing prosecutions.
