So this overrules all eviction laws in the state for the students who established residency there? Having gone through the process and education of throwing someone out of my house, I’d likely go with not an open and shut case. After all, the presumptive requirement of membership is no longer a factor since the fraternity no longer has permission to use the building.
They didn't have a lease. They had, at best, an agreement with SAE to live in the frat house for a specified rent. SAE has disbanded the chapter so really they have no agreement with anyone and the university wants its property back.
And it's not like they're on the street. The university has said that they can contact the Dean of Students if they need special arrangements for housing.
