Hannah Dugan Case: Former Milwaukee Judge Seeks Conviction Reversal Over New ICE Ruling

In a quiet federal courtroom where the usual tension of sentencing was replaced by dense technical debate, lawyers for disgraced former Milwaukee County Circuit Judge Hannah Dugan made a dramatic, last-ditch bid to erase her felony conviction.

Dugan, 67, who resigned from the bench in January 2026 under the shadow of a jury’s guilty verdict, was scheduled to receive her sentence on June 3, 2026. Instead, U.S. District Judge Lynn Adelman postponed those proceedings indefinitely. The pause allowed Dugan’s defense team to argue that a recent federal appeals court ruling in Virginia fundamentally dismantles the legal foundation under which she was convicted of obstructing federal immigration agents last year.

A Disputed Escape Route

The high-stakes legal maneuvering traces back to a chaotic afternoon on April 18, 2025, inside the heavily trafficked Milwaukee County Courthouse.

The air outside the courtroom Branch 31 was thick with expectation. Six federal agents from U.S. Immigration and Customs Enforcement (ICE) waited in the public corridor to arrest Eduardo Flores-Ruiz, an undocumented immigrant appearing before Dugan for a routine state battery hearing.

According to court records, when Dugan learned of their presence, she confronted the agents, demanding they check in with the chief judge because she believed their administrative warrant was insufficient for a courthouse arrest. While the agents were momentarily diverted, Dugan returned to her bench, fast-tracked Flores-Ruiz’s hearing by scheduling a Zoom date, and directed him to slip out through a private door normally reserved for jurors.

Though Flores-Ruiz was captured minutes later following a brief, desperate foot chase outside the building, the fallout for Dugan was immediate. A week later, FBI agents led her out of the courthouse in handcuffs. A federal jury ultimately convicted her of felony obstruction of an official proceeding in December 2025, a case the Justice Department heralded as a prominent example that "no one is above the law."

The Virginia Precedent

Now, Dugan’s bid for freedom hinges on a technical definition originating hundreds of miles away.

In April 2026, the 4th U.S. Circuit Court of Appeals in Virginia reversed a lower court's ruling in a strikingly similar case involving an immigrant who had escaped federal custody. The appeals court panel determined that a localized enforcement action, such as an ICE arrest operation or the execution of an administrative warrant, does not legally constitute a "pending proceeding" under federal obstruction statutes.

Dugan’s attorney, Steven Biskupic, brought that newly minted interpretation into the Milwaukee federal courtroom. He argued that because there was no active, formal proceeding happening in relation to the ICE warrant when Dugan opened the jury room door, the theory behind her conviction is entirely invalid.

"The lone Court of Appeals in the country to address this issue has said that’s not valid and the conviction is overturned," Biskupic told the court, pushing for an acquittal.

Clashing Timelines in the Courtroom

The prosecution remains entirely unswayed by the shifting legal winds in Virginia. Acting U.S. Attorney Richard Frohling argued that the 4th Circuit’s decision is non-binding in Wisconsin—which sits under the jurisdiction of the 7th Circuit—and described the Virginia ruling as a legal outlier.

During the arguments, Judge Adelman pressed federal prosecutors on how broad and elastic the definition of an immigration "proceeding" could be. When asked if such a proceeding under the law could span years, Frohling replied that it depends entirely on the context—it could last a couple of years or a couple of minutes.

"The court should stick with its ruling," Frohling urged, maintaining that the trial evidence proved Dugan deliberately disrupted a federal enforcement action.

Dugan sat quietly throughout the arguments, watching a legal battle that represents one of the most significant judicial tests of the federal government's immigration enforcement powers inside local government buildings. If Judge Adelman sides with Dugan and vacates the jury's verdict, it will nullify a major, high-profile conviction. If he denies the motion, Dugan faces up to five years in prison, though her lack of a prior criminal record means probation is far more likely.

Adelman concluded the hearing without issuing a ruling, leaving the fate of the former judge hanging in the balance.
