What differentiates a main motion from a subsidiary motion?

The distinguishing factor between a main motion and a subsidiary motion is that a main motion introduces a proposal or item of business for consideration by the assembly, essentially setting the agenda for discussion. In contrast, a subsidiary motion is used to modify, delay, or dispose of the main motion in some way. This means that while a main motion serves to introduce new business, subsidiary motions serve to refine or alter the discussion surrounding that business.

This hierarchy is essential in parliamentary procedure, as it creates a structured environment for debate and decision-making. By understanding that the main motion is the foundational element being discussed, members can utilize subsidiary motions to navigate and shape the conversation effectively, ensuring all voices can contribute to the details surrounding primary proposals.
