I'm posting this for information purposes only as it is clear that a large number of marshals don't have access to the Blue Book, I'm also deliberatly starting a new thread so as not to hijack Julian's existing thread.

I haven't checked the rest of the Blue Book for anything else that might also apply so I make no guarantee that there aren't other provisions that apply....
