What is the lowest ranking motion in parliamentary procedure?

The main motion is indeed the lowest ranking motion in parliamentary procedure because it serves as the fundamental way for members to introduce new business or proposals for discussion. Unlike subsidiary motions, which can modify or affect the main motion, and privileged or incidental motions, which address urgent matters or procedural issues, the main motion is the starting point for deliberation. It holds the least rank since all other types of motions are meant to either further the discussion of the main motion or address specific urgent situations that arise during meetings. Understanding the role of the main motion in the hierarchy of motions helps clarify the structured approach that parliamentary procedure provides in organizing discussions and decision-making within groups.
