What should members ensure before proposing a main motion?

Before proposing a main motion, members should ensure that there are no pending motions. This is important because existing pending motions take precedence and must be resolved before new business can be introduced. If a member attempts to introduce a new main motion while there are pending motions, it could lead to confusion and disorganization within the meeting. The structure of parliamentary procedure relies on clarity and order, allowing members to address one matter at a time for effective discussion and decision-making.

While the other options highlight valuable considerations—like ensuring all members are present for inclusivity, understanding motion procedures for effectiveness, and discussing topics in prior meetings for preparedness—they do not have the same critical impact on the process of proposing a main motion. The presence of pending motions is a fundamental rule within parliamentary procedure that cannot be overlooked, as it would compromise the established order necessary for a productive meeting.
