Wow....that is an interesting amendment. I'm curious as to what incident(s) prompted someone to propose an alumna expulsion amendment

I agree with BalorBean that the amendment is very vauge. I would assume it would have to be something serious like stealing money from the chapter or hazing members as others have suggested. Or maybe they want it to be vague because they aren't sure what to expect.
On a side note....I too am happy about the 25 year pin and it's design sounds lovely.
