The only circumstance I'm concerned with is what he was actually led to believe. Was he told...
A)you do this, this, and that, and at X time, we'll review and MAYBE you can return to school.....
or
B) you do this, this, and that, and at the time of review, you'll be allowed to return.
I dont know either way. But if it was A, and if the former staff or Avery himself interpreted that as automatic reinstatement, that's not on the university at all. it's on the staff and/or Avery. If it was B, and he did what he was supposed to do, I would think the school has a full blown obligation to reinstate him.
i dont know nothing either way. Just speculating the scenarios. There's a reason he stuck around and assumingly did what he was supposed.
