A U.S. District judge on Tuesday rejected Milwaukee County Judge Hannah Dugans request to dismiss allegations that she helped an undocumented immigrant evade federal authorities earlier this year.Dugan was arrested in April after allegedly helping Eduardo Flores-Ruiz avoid plainclothes Immigration and Customs Enforcement (ICE) agents who were trying to serve him a warrant.Her attorneys argued she is entitled to judicial immunity for her official acts. They also said the federal government overstepped its authority by arresting and charging her.The defense team also claimed the charges violate the U.S. Constitutions 10th Amendment and the principle of separation of powers.FEDERAL CASE AGAINST MILWAUKEE JUDGE ACCUSED OF CONCEALING ILLEGAL MIGRANT SHOULD CONTINUE, JUDGE RECOMMENDSDugans attorneys further argued that Dugan can only be charged with conduct "wholly unrelated" to her judicial duties, such as taking bribes or violating constitutional rights, though she has not been accused of either in this case.U.S. District Judge Lynn Adelman ruled on the motion Tuesday."Ultimately, as the Supreme Court has stated, the official seeking absolute immunity bears the burden of showing that such immunity is justified for the function in question," Adelman wrote, adding that Dugan has not done so here. "I cannot say as a matter of law that the defendants alleged conduct falls within even this more limited version of immunity."MILWAUKEE JUDGE NOT IMMUNE FROM CHARGES AFTER ALLEGEDLY HELPING ILLEGAL IMMIGRANT EVADE ICE, PROSECUTORS SAY"There is no basis for granting immunity simply because some of the allegations in the indictment describe conduct that could be considered part of a judges job," Adelman added.Prosecutors allege that Dugan helped Flores-Ruiz and his attorney exit her courtroom through a back door on April 18, after learning that ICE agents were in the building to arrest him.TRUMP ADMIN MAY NOT DEPORT MIGRANT TO CONGO DURING IMMIGRATION PROCEEDINGS, FEDERAL JUDGE RULESA federal indictment alleges Dugan "falsely" told the agents they needed a judicial warrant and directed them to go to the chief judges office. Dugan then addressed the case off the record instead of holding the scheduled hearing. Flores-Ruiz faces three misdemeanor battery charges, and despite Dugans efforts, he was arrested.Adelman has scheduled a hearing about Dugans motion for Sept. 3.Both federal prosecutors and Dugans defense team have said they would like a trial to begin before the end of the year. No trial date has been set.Fox News' Patrick McGovern and Rachel Wolf contributed to this report.
