Former Milwaukee County Circuit Judge Hannah Dugan’s legal fight took another sharp turn this week after a federal judge refused to throw out her obstruction conviction in a case that has become one of the most closely watched courtroom clashes of the Trump-era immigration crackdown.
The ruling keeps Dugan’s conviction alive and pushes the former judge closer to sentencing, months after a jury found her guilty of obstructing federal immigration agents during a courthouse incident involving Eduardo Flores-Ruiz, an undocumented immigrant who had appeared in her courtroom.
A Courthouse Moment That Became a National Case
The case began in April 2025, when immigration agents arrived at the Milwaukee County courthouse seeking to detain Flores-Ruiz. According to the government’s case, Dugan learned that agents were present, questioned the nature of their warrant, directed them toward the chief judge’s office, and then helped Flores-Ruiz leave through a private or nonpublic exit.
Flores-Ruiz was later arrested outside the courthouse after a brief chase, but the incident had already lit a fuse. Within days, Dugan was arrested by the FBI. What might have been a local dispute over courthouse procedure became a national symbol in the larger war over immigration enforcement, judicial independence, and the limits of courtroom authority.
Dugan was eventually convicted in December 2025 on a felony obstruction count. The jury found her guilty of obstructing a federal proceeding, though she was acquitted of a separate misdemeanor count alleging she concealed a person from arrest. After the conviction, she resigned from the Milwaukee County Circuit Court, ending a judicial career that had placed her at the center of Wisconsin’s legal community.
Why the Judge Refused to Toss the Conviction
The heart of the latest ruling came down to a phrase that sounds dry but carries enormous weight: “pending proceeding.” Dugan’s attorneys argued that the ICE operation did not qualify as a pending federal agency proceeding under the obstruction law used to convict her.
They pointed to a recent Fourth Circuit decision in a Virginia immigration case, in which an appeals court found that a similar ICE action did not meet the legal standard required for an obstruction conviction. In other words, the defense argued that if there was no legally recognized “pending proceeding,” then there could be no obstruction of that proceeding.
Judge Adelman rejected that argument. In his order, Adelman said the Virginia case did not control Dugan’s case because Wisconsin sits in a different federal circuit. He also found that the facts were different.
In Dugan’s case, he reasoned, ICE was not simply acting like ordinary police officers making a routine arrest. The operation was tied to immigration removal powers that allow ICE to issue administrative warrants and carry out removal actions without first going through a traditional courtroom process.
That distinction mattered. Adelman wrote that ICE’s role in removal proceedings made the case different from ordinary law enforcement activity. Because ICE can issue its own warrants and carry out removal decisions, the attempted arrest of Flores-Ruiz could be treated as part of a broader administrative immigration process.
A Case Bigger Than One Former Judge
Dugan’s case has never been just about one courtroom door. From the start, it carried the temperature of the national immigration debate. Supporters saw her prosecution as an aggressive example of the federal government targeting local officials who resisted or questioned immigration enforcement.
Critics saw her conduct as a direct challenge to federal authority, made worse by the fact that she was wearing a judge’s robe at the time. That is why the case has drawn attention far beyond Milwaukee. Courthouses have long been sensitive spaces in immigration enforcement debates.
Immigrant advocates argue that courthouse arrests can discourage witnesses, defendants, and families from participating in the justice system. Federal immigration officials argue that courthouses are controlled environments where agents can safely locate people they are seeking to detain.
Dugan’s case dropped straight into that conflict. Her defenders have argued that judges must be able to manage their courtrooms and protect the dignity of local judicial proceedings. They have also raised concerns about immigration agents appearing in courthouse spaces with administrative warrants rather than judicial warrants.
Prosecutors, however, argued that Dugan crossed a bright line. They did not merely accuse her of asking questions or asserting courtroom authority. They said she used her position to redirect federal agents and help a person avoid immediate arrest. The jury accepted enough of that argument to convict her on the felony count.
That makes Adelman’s ruling especially important. By refusing to overturn the verdict, he signaled that the conviction was not undone by the defense’s new legal argument or by the Fourth Circuit decision from Virginia.
What Happens Next
Dugan faces a maximum sentence of five years in prison, though reports have noted that federal sentencing guidelines may point toward probation because she has no criminal history and the conviction involves a nonviolent offense. Still, the stakes are serious.
A felony conviction has already ended her time on the bench. Sentencing could result in probation, fines, supervised release, or another penalty as determined by the court. The judge has not yet set a new sentencing date, but the postponement that allowed him to consider the defense’s latest argument is now resolved.
That means the case is moving forward again. Dugan’s lawyers are expected to appeal, which could place the dispute before a higher court. If that happens, the legal fight over whether ICE’s arrest operation constituted a pending proceeding may not be resolved. It could become part of a larger federal argument over how obstruction laws apply to immigration enforcement.
For now, however, the legal scoreboard is clear. A jury convicted Dugan. A federal judge has refused to disturb that conviction. And a case that began with a tense moment inside a Milwaukee courthouse now stands as one of the most dramatic tests of how far local judicial authority can extend when it collides with federal immigration authority.
Dugan once controlled the courtroom. Now, the courtroom controls what comes next.
