Are we to believe that they couldn't pencil it in, and fax it to the other side on the spot? For that matter, are we to believe that the other side didn't have representation there, at the hearing?
This is a game, that's all. I cannot believe that in any "normal" case, a minor typo wouldn't have been handled in a more common-sense manner. Even in a case like this, if the roles were reversed, I suspect the plaintiff would have had a red carpet rolled out for him, and all obstacles swept out of his way to expedite "prompt justice."
