April 2012: The Alpha Chapter of Sigma Chi is closed indefinitely by its national organization after "repeated patterns of inappropriate behavior involving hazing and alcohol." The chapter had also been rendered a nine-month suspension in 2010 for damaging rooms in a Columbus hotel.
August 2012: A fireworks battle — later leading to a discovery of a large cache of illegal drugs — between neighboring fraternities Sigma Alpha Epsilon and Phi Kappa Tau puts the organizations on suspension. Sigma Alpha Epsilon was allowed to return as early as last year but the university lists the group as unrecognized still. Phi Kappa Tau is listed as recognized by the university.
December 2010: Phi Gamma Delta is suspended for six months after hosting an off-campus party where police were called to investigate underage drinking.
May 2010: Two Miami University sororities make national news after details emerge about their wild sorority formals. Pi Beta Phi is suspended for one year after event organizers say the sorority flipped tables, urinated in sinks and broke decorations. Alpha Xi Delta is suspended for two years after damaging the National Underground Railroad Freedom Center in Cincinnati during their sorority formal. After Alpha Xi Delta's return, the university again revokes their recognition for "prohibited use of alcohol." The chapter was eligible for return last year but is still listed as "unrecognized."
