I do know of situations where faculty at gateway military and first-responder schools like this, and even higher education for professional degrees, have put out the word that "If you're X, you will not pass this class, no matter what you do," but that's extremely difficult to get away with these days, and all those incidents happened quite awhile ago.
Does sound a lot like this one is more a product of just lowering the bar for the few, rather than raising it for them.
