Simplified Rules of Order
Objection to the Consideration of a Question
If a member believes that it would be harmful for a meeting even to discuss a main motion, he/she can raise an objection to the consideration of the question; provided debate on the main motion has not begun or any subsidiary motion has not been stated.
The motion can be made when another member has been assigned the floor, but only if debate has not begun or a subsidiary motion has not been accepted by the chair. A member rises, even if another has been assigned the floor, and without waiting to be recognized, says, "Mr. Chairman, I object to the consideration of the question (or resolution or motion, etc.)." The motion does not need a seconder, is not debatable, and is not amendable.
The chair responds, "The consideration of the question is objected to. Shall the question be considered?"
A two-thirds vote against consideration sustains the member's objection. (The two-thirds vote is required because the decision in effect amends the agenda.) The motion can be reconsidered, but only if the objection has been sustained.
