In 2010 the Kansas Supreme Court Disciplinary Administrator brought formal professional ethics charges against Kline before the Kansas Supreme Court based on perjury, an illegal file transfer, misleading legal guidance that Kline had provided to the grand jury in the Johnson County clinic case, the O'Reilly appearance, and several other matters. Kline's ethics trial began on February 21, 2011. He testified that he had the right to deceive state agencies to gain information in abortion investigations and that he had no duty to promptly notify a trial judge that he had provided flawed information.
