Usually this means a low GPA? I don't know of any other "rule", other than "you must be a student taking at least xx hours."

> others have sorted pasts
I assume you mean "sordid"? As in vandalism? alcohol violations?

If you have facts to bring up, there's nothing unethical as long as you present the whole truth. Say, they got drunk, and destroyed a park bench. They replaced the bench and did a day of community service, like raking leaves. That would be the whole truth.

Rechartering involves many steps, both for your campus as well as their national. You can't make them fail, but they can make themselves fail. Their (hopeful) national usually has a risk management team, I don't think much will get past them?

Ideally, you probably don't want them to fail, but get their act together, and be a good house? Realistically, that might not be practical for the whole group? Perhaps a couple? But a solid coaching effort, of both students and faculty, would not only be ethical, but also a feather in your house's cap.
