The University of Arizona placed all 21 chapters in its Interfraternity Council on an interim activities suspension Monday, Oct. 5, as the university responds to misconduct reports and investigations involving fraternity organizations. The restrictions prohibit chapters from hosting, attending, participating in or sponsoring organizational activities. Business meetings are still allowed. Nearly half of the chapters are under investigation or have been the subject of misconduct reports, according to Dean of Students Chrissy Lieberman. Chapters that were in good standing before the suspension can return to that status after an adviser attends one of three initial mandatory meetings. Advisers will then have to attend quarterly meetings; a missed meeting could put a chapter’s standing at risk and jeopardize its ability to remain on campus, Lieberman wrote in a letter. Some chapters were already barred from activities, including contact with new-member classes, after spring 2026 conduct violations or while investigations continue. Lieberman said some cases also involve criminal investigations. The reported allegations range from physical assault and hazing to drugs, alcohol and unsafe conditions, she said; the allegations have not been established as facts in every case. Lieberman said her office is at capacity for the number of organizational cases it can investigate at once, and that every current case involves an Interfraternity Council chapter. The university will take interim measures and work with the University of Arizona Police Department, she said, but investigations will take time and may limit chapters’ events, philanthropy and new-member education. The university announced expanded hazing-prevention initiatives in July. The latest suspension follows a separate allegation that a fraternity required new members to consume live goldfish and large quantities of alcohol.
