The legal team representing a Wisconsin judge accused of helping a man evade immigration authorities recently expanded their motion to dismiss the case.

Judge Hannah Dugan’s attorneys say that she is entitled to judicial immunity for her official acts and that the federal government overstepped its authority by arresting and charging her. Additionally, the legal team asserts in its memo that the charges violate the Constitution’s Tenth Amendment and the principle of separation of powers.

They further argue that Dugan can be charged for conduct that is “wholly unrelated” to her duties as a judge, such as taking bribes or violating someone’s constitutional rights. Dugan is not accused of doing either of those things in this case.

“The indictment itself is an ugly innovation. Its dismissal will not be,” Dugan’s attorneys write in the memo.

Footage released last week appears to show Dugan interacting with the ICE agents in a hallway before allegedly escorting Flores-Ruiz and his attorney out a private exit.

On May 13, a grand jury indicted Dugan on federal charges of concealing a person from arrest and obstruction of justice. Dugan pleaded not guilty and is scheduled to go to trial in July. If found guilty of both charges, she could face up to six years in prison and $350,000 in fines.
