The legislation states that "An extraordinary meeting of a parish council may be called at any time by the chairman of the council." It doesn't elaborate on the issue of who signs the agenda. Conversely, if the chairman fails to call an extraordinary meeting when asked to do so by any two councillors, those two councillors may, after seven days, call an extraordinary meeting and the two councillors sign the agenda for that meeting. To add to the confusion, the fact that the Chairman may call an extraordinary meeting doesn't necessarily prevent the Clerk from doing so.
