A federal appeals court has affirmed the felony obstruction conviction of former Milwaukee County Circuit Judge Hannah Dugan, who was found guilty of helping a previously deported immigrant slip out of her courtroom to avoid arrest by Immigration and Customs Enforcement officers.
The ruling closes one chapter in a case that drew national attention and tested a sharp question: Can a sitting judge use the power of the bench to shield someone from a lawful federal arrest?
The incident took place on April 18 in Dugan's Milwaukee County courtroom. ICE agents arrived to arrest Eduardo Flores-Ruiz, an immigrant who had previously been deported and then illegally reentered the United States. Flores-Ruiz was present for a court proceeding when agents attempted to take him into custody on a civil immigration warrant.
Prosecutors laid out a sequence of deliberate steps Dugan took to frustrate the arrest. She challenged the validity of the ICE civil warrant, then directed the agents to speak with the chief judge rather than carry out the detention. She cut Flores-Ruiz's hearing short. And then, critically, she allowed him to leave through a non-public door, one that ordinary members of the public would not use, the Washington Times reported.
Flores-Ruiz walked out of the courthouse. ICE agents were forced to track him down and arrest him on the street, outside the controlled security environment of the building.
A federal jury convicted Dugan on the felony obstruction charge but acquitted her on a separate misdemeanor count of concealing a person who was a target of arrest. The split verdict suggested jurors drew a line between Dugan's broader pattern of interference and the narrower question of whether she physically hid Flores-Ruiz from agents.
The felony conviction, however, carried the weight. It established that a judge used her authority and access to court facilities to obstruct federal officers carrying out their duties. The case became a flashpoint in the broader national fight over whether ICE should be permitted to make arrests inside courthouses, a practice that immigration advocates have long opposed but that federal authorities defend as safer and more orderly than street arrests.
That safety argument became central to the prosecution's case. U.S. Attorney Brad D. Schimel framed the street arrest that followed Dugan's interference as proof of the danger her actions created.
"This dangerous scenario illustrated why courthouse arrests are preferable."
Schimel argued that courthouses provide controlled environments with security screening, making them far safer for agents, bystanders, and the person being detained. Forcing agents to pursue Flores-Ruiz outside the building stripped away those protections.
Dugan challenged her conviction on appeal. The appeals court, however, upheld the felony conviction, finding that the trial court proceedings and the jury's determination were sound. The ruling means Dugan's conviction stands, and she faces sentencing on the felony charge.
The decision lands at a moment when federal authorities have been ramping up scrutiny of public officials who allegedly interfere with immigration enforcement. In Minnesota, FBI agents have subpoenaed state officials over separate ICE obstruction allegations, signaling that the Dugan case is not an isolated episode but part of a broader pattern the federal government intends to confront.
The Department of Homeland Security treated the conviction and its appellate affirmation as a message to other officials who might consider similar interference. Homeland Security Assistant Secretary Tricia McLaughlin did not mince words about what the case should communicate.
"The conviction should warn others against anti-ICE behavior."
That statement frames the Dugan case not merely as an individual prosecution but as a deterrent. Federal officials want judges, mayors, police chiefs, and other local and state authorities to understand that obstructing immigration enforcement carries real criminal consequences, even for people who hold positions of public trust.
The framing echoes other federal enforcement actions targeting officials accused of obstructing lawful operations. The Justice Department has also opened investigations into political leaders in Minnesota over similar obstruction claims, building a body of cases that collectively raise the legal stakes for anyone in government who tries to stand between ICE and its targets.
Dugan's case sits at the intersection of two colliding principles. Immigration advocates argue that courthouse arrests deter undocumented immigrants from appearing for their own legal proceedings, creating a chilling effect on access to justice. They contend that people who fear arrest at the courthouse door will skip hearings, avoid filing protective orders, and refuse to testify as witnesses.
Federal authorities counter that courthouses are among the safest places to make an arrest. Everyone entering has passed through security screening. The environment is controlled. Officers know who is present and where exits are located. A courthouse arrest avoids the unpredictable variables of a street encounter: traffic, bystanders, potential flight into dangerous areas, and the absence of metal detectors.
Prosecutors used Dugan's case to drive that point home. By helping Flores-Ruiz leave through a back door, Dugan forced agents into exactly the kind of uncontrolled street scenario that courthouse arrests are designed to prevent. The fact that Flores-Ruiz had already been deported once and reentered illegally gave prosecutors additional ammunition: this was not a first-time border crosser caught up in a bureaucratic mix-up but someone who had already been removed and returned.
The broader legal fight over courthouse arrests has played out in courtrooms and statehouses across the country. Several states and municipalities have adopted policies discouraging or restricting ICE activity in and around court facilities. The Dugan conviction, now upheld on appeal, sends a counter-signal: individual officials who take matters into their own hands and actively obstruct agents face personal criminal liability.
Dugan is no longer on the bench. The felony conviction effectively ended her judicial career. She now faces sentencing, and the appellate affirmation removes one of her remaining avenues to overturn the jury's finding.
The case also raises questions about judicial accountability in Wisconsin more broadly. The state's courts have become a political battleground in recent years, with fights over the ideological balance of the state supreme court drawing national attention and money. Dugan's prosecution adds another layer to that story, demonstrating that individual judges can face severe consequences when their conduct crosses from legal disagreement into criminal obstruction. Wisconsin's judiciary has seen significant political upheaval, including the departure of a longtime conservative justice that left the state's liberal court majority without a check.
Authorities have not publicly confirmed whether Dugan's case has prompted any internal reviews of courthouse security protocols or policies governing how judges interact with federal agents who arrive to execute warrants. Investigators will also need to determine whether any other courthouse personnel played a role in facilitating Flores-Ruiz's departure through the non-public exit.
The Dugan conviction fits into a larger federal enforcement posture that has grown more aggressive toward officials who resist immigration operations. Across the country, DHS and the Justice Department have signaled that obstruction by public servants will be treated as a criminal matter, not a policy disagreement.
That posture has produced a growing number of confrontations between federal authorities and state or local officials who view their resistance as principled. Appeals courts have become key arenas for resolving these clashes, as seen in recent appellate rulings affirming broad DHS authority over immigration protections.
For conservative legal observers, the Dugan case represents something straightforward: a judge broke the law to help someone evade federal officers, a jury convicted her, and an appeals court agreed. The legal system worked the way it is supposed to work, even when the defendant was someone who once sat on the other side of the bench.
Whether McLaughlin's warning lands with other officials remains to be seen. But the message from the appeals court is plain enough: a robe does not make you immune, and a gavel does not give you the authority to override federal law.
