In parliamentary procedure, a motion is a formal proposal by a member of a deliberative assembly that the assembly take certain action. Such motions, and the form they take are specified by the deliberate assembly and/or a pre-agreed volume detailing parliamentary procedure, such as Robert's Rules of Order, Newly Revised; The Standard Code of Parliamentary Procedure; or Lord Critine's The ABC of Chairmanship. Motions are used in conducting business in almost all legislative bodies worldwide, and are used in meetings of many church vestries, corporate boards, and fraternal organizations.
