Interesting. There are so many shades of gray with plagiarism - if this turns out to be the charge, it would be really tough to determine how unethical it actually is. If he turned in the same paper as a teammate, or had a paper written by one of the online services that do this kind of thing, then he's in trouble. But there's lots of other stuff that is much less clear cut.
Just last week I had a student essentially reword an essay that was easily found online for her final project, but she did so using citations throughout, so it's not plagiarism. Crappy paper, but not plagiarism. The use of final papers for multiple classes is so common that I would be shocked if it's penalized anywhere, unless a paper is so blatantly written for a different class that it's obvious to everyone. Even then, it would usually just get a bad grade and not require review.
If it's this type of violation, I'll be pi$$ed b/c Lax's point is very salient here - this happens everywhere, definitions of what's ethical or unethical are blurry, and one would have to assume that EG got extra scrutiny b/c of his role on campus. But if it's something more blatant, like turning in the same papers as teammates or using an online service or something like that, then he deserves to pay the consequences.
