Is it possible to withdraw a resignation after it has been submitted?

A resignation is a Request to Be Excused from a Duty. It may be withdrawn in the same manner as any motion may be withdrawn -- that is to say, before the proposed resignation has been placed before the assembly by the chair stating the question on its acceptance, it may be withdrawn without the consent of the assembly, but it may not be withdrawn without permission of the assembly once it has been placed before the assembly for its approval.
