Which parliamentary procedure allows a member to bring up a substantive matter for discussion?

The main motion is the parliamentary procedure that enables a member to introduce a substantive matter for discussion within a meeting. This type of motion is essential as it provides the means for members to propose new ideas, policies, or actions that they believe the assembly should consider. Once a main motion is made, it is opened for debate and can be voted on, allowing members to express their opinions and ultimately make a decision on the proposed issue.

Unlike the other options, which serve different purposes in parliamentary procedure, the main motion specifically focuses on introducing new topics rather than managing the agenda or modifying existing motions. Points of order address procedural issues and ensure that meetings run smoothly, while a table motion is used to temporarily set aside a matter under discussion. An amendment, on the other hand, is used to modify an existing motion rather than introducing a new one. Thus, the main motion stands out as the appropriate tool for bringing substantive matters to the floor for discussion.
