 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.
