On October 8, 1972, the men of Alpha Phi voted to admit women into their chapter. They alerted National Headquarters, and National Secretary Robert H. Rubin replied telling Alpha Phi not to administer any degree of ritual until the issue could be discussed in person. When Rubin arrived at Rutgers on November 11, 1972, he learned that the first degree of ritual had been administered, which began formal probationary membership. Alpha Phi's charter was immediately revoked and their chapter was placed on suspension. On November 13, the former Alpha Phi chapter formally reorganized as Mu Upsilon Alpha. On October 7, 2007, Mu Upsilon Alpha became a chapter of Mu Beta Psi.
