Which type of motion ranks lowest in parliamentary procedure?

In parliamentary procedure, the hierarchy of motions is crucial for understanding how meetings are conducted and decisions are made. The main motion is designed to introduce new business or a proposal that the assembly must consider. It ranks lowest because it must be addressed before any other related or procedural motions, meaning that it serves as the foundation for discussion but does not hold any inherent priority over other types of motions.

Secondary motions, such as amendments and motions to refer, seek to modify the main motion or give it context, thus they hold a higher rank since they cannot be addressed until the main motion has been established. Incidental motions address issues that arise in the course of handling business, and privileged motions deal with urgent matters that require immediate attention, both of which have greater importance than the main motion. Therefore, while the main motion is essential for introducing proposals, it is subordinate to other motions that prioritize procedure and immediate concerns.
