Previous notice can be given in one of two ways. A member either announces it at a meeting of the assembly, in which case the secretary is to record it in the minutes, or notifies the secretary outside of the meeting. In either case, the secretary is to include notice of the motion in the call of the next meeting. Certain motions – specifically, the motions to adopt or amend special rules of order, rescind, repeal or annul or amend something previously adopted, amend standing rules in a convention, discharge a committee, and postpone an event or action previously scheduled – are more difficult to pass if previous notice has not been given. Often, a majority of the entire membership or a two-thirds vote is required if previous notice has not been given. This rule is intended to protect the rights of absent members.
