Any participant may raise a boundary concern, and the chair, moderator, host, staff lead, counsel where present, or authorized meeting steward may formally stop or redirect the discussion.
Safe-meeting discipline should not depend only on seniority. A junior participant, observer, staff member, expert, or institutional representative should be able to say that a topic appears restricted. Once raised, the chair or moderator should respond immediately.
Participants should not be penalized for making a good-faith stop-line intervention. The purpose is to protect the room and the record, not to embarrass the speaker.
If a chair or moderator fails to stop a restricted discussion, another authorized person should intervene. If the discussion cannot be controlled, the meeting may be paused or ended.
Safe-meeting authority exists to preserve trust. It is not optional.
