( CNN ) Two fraternities at the University of Virginia say they wo n't sign an agreement dictating new safety procedures after a student 's claim of being gang raped . The policy calls for fraternities to have security at doors , guard their stairs , have keys to each room , sober brothers at parties and to eliminate pre-mixed drinks . In November , the university suspended all fraternities and associated parties until this month after a Rolling Stone magazine article about the student 's claims . Despite scrutiny of the article 's depiction of the alleged rape of a then-UVA freshman , identified in the article as Jackie , the university stuck to its promise to review how sexual assault is handled and to make Greek life safer . UVA gave its fraternity members until Friday to sign the agreement if they wanted to have the suspension lifted . But Alpha Tau Omega and Kappa Alpha Order released statements on their national fraternity letterhead saying they would not do so . They said the university unfairly punished members of Greek life when it uniformly suspended social activities two days after the Rolling Stone article was published , and said they are concerned the demands will create new liability and `` set a dangerous precedent of an erosion of student and organizational rights . '' Instead , both fraternities plan to ignore the new rules set by UVA and resume activities . The university said the rules were developed by student groups and said it wo n't comment until after the Friday deadline for fraternities to sign the agreement has passed . A source familiar with the thinking of the national fraternities said this could result in litigation if UVA tries to limit the fraternities that wo n't sign the new agreement . The Washington Post reports that Phi Kappa Psi is one of the fraternities that signed the agreement and remains committed to improving safety during events . Jackie told Rolling Stone that she was assaulted by seven men at a Phi Kappa Psi party . In the weeks that followed the article , the Washington Post and other news organizations began scrutinizing the details of Jackie 's story . CNN spoke to Jackie 's friends , who told a different version of events from that night , and Phi Kappa Psi produced records that seemed to dispute what she said happened . Charlottesville Police investigated after the story was printed , and said earlier this week that police found no `` substantive basis to confirm that the allegations raised in the Rolling Stone article occurred at Phi Kappa Psi . '' Police have not said whether they believe Jackie was raped . Rolling Stone apologized and launched an investigation of its own . The magazine editor acknowledged that the writer never contacted some of the witnesses or any of the accused .
