MADISON, Wis. (AP) — A Wisconsin judge charged with helping a man who is in the country illegally evade U.S. immigration agents who were trying to detain him at her courthouse filed a motion to dismiss the case on May 14, arguing that there’s no legal basis for it.

Attorneys for Milwaukee County Circuit Judge Hannah Dugan argue in their motion that her conduct on the day in question amounted to directing people’s movement in and around her courtroom, and that she enjoys legal immunity for official acts she performs as a judge. They cite the 2024 U.S. Supreme Court ruling in President Donald Trump’s 2020 election interference case that found that former presidents have absolute immunity from prosecution for official acts that fall within their “exclusive sphere of constitutional authority” and are presumptively entitled to immunity for all official acts.

“The problems with the prosecution are legion, but most immediately, the government cannot prosecute Judge Dugan because she is entitled to judicial immunity for her official acts,” the motion says. “Immunity is not a defense to the prosecution to be determined later by a jury or court; it is an absolute bar to the prosecution at the outset.”

The judge overseeing her case is Lynn Adelman, a former Democratic state senator. Former President Bill Clinton appointed him to the bench in 1997.

Kenneth Gales, a spokesperson for the U.S. attorney’s office in Milwaukee, declined to comment on the motion.

Federal prosecutors charged Dugan in April with obstruction and concealing an individual to prevent arrest. A grand jury indicted her on the same charges on May 13. She faces up to six years in prison if convicted of both counts.

Her attorneys insist Dugan is innocent. She’s expected to enter a not guilty plea at her arraignment on May 15.

Dugan’s arrest has escalated a clash between the Trump administration and Democrats over the Republican president’s sweeping immigration crackdown. Democrats contend that Dugan’s arrest went too far and that the administration is trying to make an example out of her to discourage judicial opposition to the crackdown.

Dugan’s case is similar to one brought during the first Trump administration against a Massachusetts judge, who was accused of helping a man sneak out a courthouse back door to evade a waiting immigration enforcement agent. That case was eventually dismissed.

According to prosecutors, Eduardo Flores-Ruiz illegally reentered the U.S. after being deported in 2013. He was charged in March with misdemeanor domestic violence in Milwaukee County and was in Dugan’s courtroom for a hearing in that case on April 18.

Dugan’s clerk alerted her that immigration agents were in the courthouse looking to arrest Flores-Ruiz, prosecutors allege in court documents. According to an affidavit, Dugan became visibly angry at the agents’ arrival and called the situation “absurd.” After discussing the warrant for Flores-Ruiz’s arrest with the agents, Dugan demanded that they speak with the chief judge and led them away from the courtroom.

She then returned to the courtroom, was heard saying something to the effect of “wait, come with me,” and then showed Flores-Ruiz and his attorney out a back door, the affidavit says. The immigration agents eventually detained Flores-Ruiz outside the building following a foot chase.

Dugan’s dismissal motion also accuses the federal government of violating Wisconsin’s sovereignty by disrupting a state courtroom and prosecuting a state judge.

“The government’s prosecution here reaches directly into a state courthouse, disrupting active proceedings, and interferes with the official duties of an elected judge,” the motion states.

The state Supreme Court suspended Dugan from the bench in April, saying the move was necessary to preserve public confidence in the judiciary. A reserve judge is filling in for her.
