I have a point of order. The motion is not moved unless you allow it to be moved. A withdrawal is not required. The motion has simply not been moved. To say you need unanimous consent to withdraw the motion implies that the motion was moved. You've said you haven't ruled whether that motion could be moved, yet you want to suspend your determination.
I'm comfortable with Mr. Angus proceeding without the motion being moved, but it is an important point for the precedent we establish that the motion is not being withdrawn. The motion was not moved and therefore, no unanimous consent is required.
