Which of the following motions is not debatable?

The motion that is not debatable is the Point of Order. This motion is used to call attention to a violation of the rules or procedures during a meeting. Since the purpose of a Point of Order is to ensure that meetings are conducted according to the established rules, it requires immediate attention and clarification from the presiding officer.

As such, it does not involve a discussion of the merits of the issue at hand and does not allow for debate. This helps maintain the focus on upholding parliamentary procedure without prolonging discussions on procedural points. In contrast, other motions such as Commit, Amend, and Main Motion all allow for debate, as they pertain to the substantive issues being discussed in the meeting.
