On Feb. 27, the university concluded an investigation into hazing allegations, finding that the Delta Sigma Phi fraternity violated university policy, including hazing, general safety hazards, theft and alcohol furnishing.

The fraternity is suspended and disaffiliated through winter 2030, according to a University of Oregon statement.

On Nov. 1, 2025, the University of Oregon Police Department received a hazing report involving DSIG, which prompted a report to the Dean of Students Office on Nov. 2. Since Nov. 7, DSIG has been on temporary suspension of new member activities, group communication, events and programming, according to the Greek Conduct website.

During the four-year suspension period, the fraternity cannot operate as a recognized student organization and will lose all privileges associated with affiliation, including the ability to participate in campus activities and events, according to UO spokesperson Angela Seydel.

The organization is eligible to reapply for recognition in spring 2030 if it complies with the terms of its suspension.

The fraternity previously faced multiple allegations of drink drugging in January 2024, which resulted in a separate interim suspension. During that suspension — and amid a university-wide fraternity alcohol event ban following a flurry of drugging allegations in winter 2024 — DSIG was alleged to have held an event involving alcohol in February 2024.

The event — which was “improperly” registered as alcohol-free — placed the fraternity on disciplinary probation through February 2027. According to university policy, probation is a period for a chapter “to reflect upon their choices.” Subsequent violations during the probation period can result in additional sanctions, including suspension or expulsion.

It is unclear what any subsequent violations may have included. The Daily Emerald is awaiting the release of public records from the university regarding DSIG’s most recent allegations.

Due to disaffiliation prohibiting fraternities from participating in university-sponsored activities, recruiting new members could prove difficult. Two previously unaffiliated organizations, Alpha Sigma Phi and Sigma Alpha Epsilon, agreed to comply with the terms of their suspension.

“The safety and well-being of students is the university’s top priority. Hazing, retaliation and behaviors that endanger community members or undermine accountability will not be tolerated,” Seydel said.

Yousif Dajani, who served as DSIG president in 2025 and whose term ended in January, declined to comment.
