Rule 9.6.  Motion to adjourn

A motion to adjourn, fixing the day and time for reconvening, shall always be in order, except when the main question has been ordered.  The motion to adjourn shall be decided without debate.  In putting the question on the motion to adjourn, when motions containing different times for reconvening have been made, the presiding officer shall put the question on the motion proposing the longest time of adjournment first, regardless of the order in which the motions were made.
