The University of Arizona has placed every fraternity chapter under an interim activities suspension as the university investigates misconduct reports involving nearly half of its 21 fraternities. The suspension, announced in a memo dated Monday by Dean of Students Chrissy Lieberman, took effect immediately. It bars chapters from hosting, attending, sponsoring or taking part in organizational activities; business meetings are the only exception. A chapter can resume activities after its adviser attends one of three mandatory meetings with Lieberman’s office. The sessions are scheduled for Oct. 6 at 6 p.m. and Oct. 7 at 8 a.m. in Bear Down Gym, Room 104, and Oct. 12 at noon in Nugent 100. Chapters must return to good standing before holding scheduled events. The university cited reports involving physical assault, hazing, drugs, alcohol and unsafe environments. Lieberman said reports from students, parents and community members continue to come in, and that every case the Dean of Students Office is currently investigating involves a fraternity. The office is at capacity for the number of cases it can handle at once, she said. Investigations are being conducted with the University of Arizona Police Department. The university’s action follows a warning from President Suresh Garimella, who met with fraternity presidents Aug. 27. Lieberman said he told chapter leaders the university would not tolerate further violations that endanger students and expected them to hold members accountable. Several chapters were already facing university discipline. The Dean of Students Office said some were on active suspension, while others were barred from working with new members. University officials also said some cases are under criminal investigation. Last month, Sigma Tau Gamma was suspended from activities after allegations that members were made to consume large amounts of alcohol and swallow live goldfish. In April, six fraternities were reported to be under university investigation. Allegations involving Sigma Alpha Mu included forced drinking and hospitalizations; Sigma Chi faced allegations involving alcohol, drugs and hospitalizations; and Phi Delta Theta was suspended over hazing allegations. Those are allegations, not findings of criminal guilt. Sigma Phi Epsilon was placed on probation through May 31, 2027, and fined nearly $4,000 over allegations including sleep deprivation, forced alcohol consumption, kidnapping and forced calisthenics. The last time the university ended recognition of a fraternity was in 2024, after Pi Kappa Phi was found responsible for hazing and other code-of-conduct violations. Under the new requirements, advisers must also attend quarterly meetings. A chapter whose adviser misses a meeting could lose good standing, putting its ability to continue activities at risk.
