A state court ruling has struck a blow to a college fraternity’s attempt to challenge an edict that it must go co-ed. Middletown Superior Court Judge Elpedio Vitale has dismissed more than 30 counts in an action filed by Delta Kappa Epsilon against Wesleyan University.

The ruling is part of a September 2014 lawsit in which the Middletown private university announced that all residential fraternities would have to become coeducational in the wake of several highly publicized incidents of sexual misconduct involving Greek organizations. The announcement made national news and raised legal issues of how much control universities have over the private organizations that own their own buildings.
