It's highly unlikely that this chapter will be allowed to keep it's charter.
In the past, when I was in school 20 years ago, a fight between brothers would have been settled "in house". In fact, I only remember one fight between brothers in the 3 1/2 years I was an undergrad. I don't think this is a common occurance at any GLO, then or now. Closing an entire chapter because of one fight seems excessive to me. But according to the article there were other problems as well.
Anyway, the new reality is lawsuits all around, fair or not. And when a chapter puts the whole fraternity at risk with a lawsuit because of a fight, underage drinking or hazing that chapter, sadly, has to go.
