In 2001, due to a series of alcohol violations the chapter was suspended by Delta Sigma Phi headquarters, and at the same time expelled from the university - this action also taken for alcohol violations. The chapter decided to continue to operate as a rogue (~unsanctioned, unrecognized) fraternity, reverting to its original (local) name of Chi Tau. Alumni members from the "Delta Alpha" era continued to own the group's house, located on West Fourth Street, the same house which had been purchased by the control board in 1991.
