This sounds good in practice but having been married to a lawyer for several years, I have come to understand only one thing about law: It's incredibly complex and outside our ability as laymen to understand its nuances and those nuances are in place for very good reasons most of the time. According to my wife, if the U of M is using either administrative or contract law to expel these students, it's probably well within their right to do so. There are multiple courts and they often have overlapping jurisdiction. Just because the criminal courts failed to meet the threshold of an indictment does not exclude other, less rigorous, courts from pursuing the matter outside the criminal justice system. As Craig pointed out, this could quite easily be a twist on the OJ case, though without the financial aspect of civil court. While the criminal courts didn't meet their (most) exacting measurements to proceed, other courts/agencies can step in and deliver verdicts using their own laws/rules.
