Federal Prosecutors Oppose Former Judge’s Bid to Overturn Conviction

In a high-profile legal battle, Milwaukee County Judge Hannah Dugan is challenging her felony conviction for obstruction, a charge stemming from a controversial courthouse incident. The case has sparked debates over the jurisdiction of immigration enforcement within courthouse walls.

Judge Dugan was foundguilty by a jury last year after she allegedly assisted a man in evading arrest by immigration agents. This incident occurred on April 18, when she reportedly led the man through an alternate exit in the courthouse.

Now seeking to overturn her conviction or secure a new trial, Dugan’s case is before U.S. District Judge Lynn Adelman. Federal prosecutors have responded to her recent appeals, asserting that her legal team is repeating arguments already dismissed by the court.

Earlier this year, Dugan’s legal team argued that the immigration agents lacked proper authority to conduct the courthouse arrest, a point not raised during the initial trial. They claim that the agents were operating on an administrative warrant, insufficient for making an arrest in such a setting.

Federal prosecutors, however, maintain that courthouse arrests are routine and permissible, citing probable cause as a sufficient basis for such actions. They argue, “Arrests at the courthouse are a common practice and can be made in a public hallway with or even without a warrant based on probable cause.”

The situation arose when agents targeted Eduardo Flores-Ruiz, who was in the courthouse for unrelated domestic-battery charges. The controversial nature of ICE operations in courthouses has stirred public debate, with some arguing it discourages immigrants from attending court proceedings and hinders justice.

Milwaukee County’s chief judge had been working on guidelines for handling ICE presence in courthouses at the time of the incident, yet no clear policy was in place. Chief Judge Carl Ashley testified during the trial that ICE arrests were believed to be lawful in public courthouse areas.

While Dugan’s attorneys argue her actions were within her judicial rights, federal prosecutors counter that her intent was to obstruct law enforcement activities. Prosecutors stated, “Nothing in that statute or in the cases cited by Dugan authorizes a Wisconsin judge to interfere with the enforcement of federal immigration law, provided she does so using the means at her disposal by virtue of her position.”

Despite her resignation in January, Dugan continues to contest the legal proceedings against her. The date for her sentencing remains unconfirmed.

Dugan resigned from her judgeship in early January. A date for her sentencing has not yet been set.
