The Interfraternity Council Senate voted to suspend the WSU chapter of Delta Upsilon in an emergency meeting on Wednesday, following allegations of sexual assault by a member of the fraternity.

The Senate was required by its bylaws to vote on the suspension within a week of Delta Upsilon’s emergency suspension by its national headquarters last week, IFC President Nathan Harris said.

He said the fraternity will lose all IFC membership rights, including Senate and interfraternity social activities, until the suspension is re-evaluated or overturned at another Senate meeting. Delta Upsilon will not lose its residence, however.

The only fraternity to vote against the suspension was Alpha Kappa Lambda. The vote required a two-thirds majority in order to pass, Harris said, and 23 of the 24 fraternities present voted in favor.

The suspension comes after an 18-year-old woman reported being sexually assaulted at the fraternity’s house earlier in September. A second woman, 17, reported that she felt ill after drinking alcohol at the house and suspected she may have been drugged.

The Delta Upsilon national headquarters said in a statement that they take these allegations with the “utmost urgency and seriousness.”
