U.S. District Judge Michael McShane’s 14-day temporary restraining order came in response to lawsuits filed by a student at Oregon State University and another at the University of Oregon following the termination of their visas earlier this month.

At a hearing in federal court in Eugene on Monday, McShane questioned federal lawyers on which regulations they were following when terminating the students’ legal status, The Oregonian/OregonLive reported.

“There has to be some regulations for when it’s appropriate and not appropriate. What regulation is ICE following here?” McShane asked, referring to U.S. Immigration and Customs Enforcement.
