Interesting point: if you earn an M.D. degree in an 8-week program, you technically have the degree, and whatever degrees you have, you're supposed to be able to attach to your name; however, attaching M.D. to one's name implies licensure and not just holding the degree, and that's the basis of the judgment (if I understand it correctly).
I think the problem lies in the 8-week program's having been somehow approved to constitute an M.D. degree. Don't they have to be accredited by something in order to do that, or does it not matter if they're outside the U.S.? What's next: correspondence courses to get an M.D.?
What about any foreign-trained M.D. who comes to the U.S. and is not licensed here - should the same injunction apply to them, that they can't use the M.D. after their name unless & until they're licensed here?
I think the whole point was that the guy was using the M.D. to portray himself as something he was not. Because of the accepted implication that M.D. "means" licensed M.D., not just degree-holder, he was maybe doing something a little fraudulent there.
