Simplified Rules of Order
A member can propose to close the meeting entirely by moving to adjourn. This motion can be made and the meeting can adjourn even while business is pending, providing that the time for the next meeting is established by a rule of the association or has been set by the meeting. In such a case, unfinished business is carried over to the next meeting.
A motion to adjourn may not interrupt another speaker, must be seconded, is not debatable, is not amendable, cannot be reconsidered, and requires a majority vote.
If the motion to adjourn has been made, but important matters remain for discussion, the chair may request that the motion to adjourn be withdrawn. A motion can be withdrawn only with the consent of the meeting.
The motions to recess and to adjourn have quite different purposes. The motion to recess suspends the meeting until a later time; the motion to adjourn terminates the meeting. The motion to adjourn should, however, be followed by a declaration from the chairperson that the meeting is adjourned.
