What type of motion ensures that the debate is kept orderly and relevant to the question at hand?

A point of order is used in parliamentary procedure to raise an objection regarding the rules of the meeting or the conduct of the debate. This type of motion helps maintain order and relevance during discussions by allowing a member to remind the chair or the assembly when they believe that rules are not being followed or that the discussion has strayed from the agenda. By addressing procedural issues, a point of order ensures that debates stay focused on the question at hand and promotes a structured environment for discussion. This is essential in any formal meeting where maintaining continuity and focus on the agenda is crucial for effective decision-making. The other types of motions listed serve different purposes — privileged motions are concerned with matters that are urgent, restorative motions are intended to return to a previous state, and main motions bring new business before the assembly, but none of them directly address maintaining order and relevance in the debate.
