When Joseph Sommers ran unsuccessfully for a seat on the Wisconsin Supreme Court this spring, he made Paul Humphrey's alleged misdeeds and the justice system's failure to stop them a campaign theme.

While he didn't make it through the primary, the Madison defense attorney succeeded in bringing some of his grievances to the high court. Justices will soon consider whether Humphrey should be disciplined for his alleged misconduct during his prosecution of Adam Raisbeck, who was acquitted by a jury of vehicular homicide in 2005.

Sommers alleged Humphrey engaged in more than 20 dishonest acts as the prosecutor pushed to convict Raisbeck for the fatal 2001 wreck. The Supreme Court's Office of Lawyer Regulation pursued three of Sommers' accusations — and a referee in August found merit in all three.

Sommers also faces possible Supreme Court discipline for his courtroom tactics in fighting Humphrey.

The Office of Lawyer Regulation charges Sommers "engaged in conduct intended to disrupt a tribunal" when he accused a Dane County judge in the Raisbeck case of running a "kangaroo court;" engaged in unethical pretrial publicity by posting his allegations about Humphrey on a Web site; and made a false statement when he alleged Humphrey had improperly had a witness in the Raisbeck case arrested.

Sommers has denied that his statements were false, and said his actions were aimed at getting a fair trial for Raisbeck.
