The statement found on page 443, lines 7-12, tells us what the chair should do if only one candidate is nominated (and the bylaws do not require that a ballot vote be taken), but if an assembly wishes to order that a vote be taken in an election, even although it isn't necessary, no rule in RONR prevents it from doing so. There are often very good reasons for ordering that a vote be taken by ballot, even if there is only one nominee. All this business about the secretary casting a ballot in the assembly's behalf is an anachronism and much ado about nothing. A number of organizations still use this procedure instead of simply declaring a sole nominee elected, and RONR isn't about to stand in their way. The same is not true with respect to the approval of minutes. Although it is not out of order to move that the minutes be approved, no vote of any kind is ever to be taken on approval of the minutes.
