> ... is fully and fairly notified about the existence ...
I'm not a lawyer, but recently I did watch the movie Legally Blond (recently for free at YouTube) where the character Elle Woods on her first day of Harvard Law School was sent out of a class for being "unprepared", that is, not having read 41 pages on "jurisdiction" or some such.
Well, Ms. Woods might have responded to the professor that she did nothing wrong and, thus, should not be sent out of class and all that because she was not "fully and fairly notified" of the existence of the assignment.
I thought of that while watching the movie (likely the movie audience was not supposed to think of such things!), but it is nice now to see none other than Justice Stevens make clear the importance of "fully and fairly". Might have been cute in the movie for the character Ms. Woods to raise such an objection that she was not notified!
