Notice is required for any substantive motion to be moved before the committee, except for a motion related to the subject at hand. That caveat, “related to the subject at hand”, means that if a motion is related to a subject that's currently being studied, it doesn't need to have notice given before it can be moved. When we're dealing with committee business, everything, any motion, would be related to the committee's business. As a result, in the committee business discussion, notice—strictly speaking—is not required.
Thank you.
