(a) The governing body of a unit of election may order an election to withdraw the unit from an authority. An election ordered under this subsection for a unit of election located in an authority consisting of one subregion governed by a subregional board created under Subchapter O may not be held if the governing body rescinds the order and notice of the election before the 45th day before election day. The governing body shall promptly give notice of the rescission in the same manner as the notice of election given under § 452.655.
(b) On the determination by a governing body of a unit of election that a petition for withdrawal under this chapter is valid, the governing body shall order an election to withdraw the unit of election from the authority.

(c) An election to withdraw may not be ordered, and a petition for an election to withdraw may not be accepted for filing, more frequently than once during each period of 12 months preceding the anniversary of the date of the election confirming the authority. If the unit of election is located in an authority consisting of one subregion governed by a subregional board created under Subchapter O, an election for withdrawal of the unit of election under this section may not be ordered, and a petition for withdrawal may not be accepted, more frequently than once during 1996 and during each sixth calendar year after that year.
