(1) The board of supervisors shall have power to alter the boundaries of the supervisors districts, voting precincts, sub-precincts and the voting place therein. If the board of supervisors orders a change in the boundaries, they shall notify the election commissioners, who shall at once cause the voter rolls as electronically maintained by the Statewide Elections Management System of voting precincts affected by the order to be changed to conform to the change so as to contain only the names of the qualified electors in the voting precincts as made by the change of boundaries. Upon the order of change in the boundaries of any voting precinct or the voting place therein, the board of supervisors shall notify the Office of the Secretary of State and provide the Office of the Secretary of State a legal description and a map of any boundary change. No change shall be implemented or enforced until the requirements of this section have been met.

(2) Only officials certified by the Secretary of State shall be authorized to implement boundary line changes in the Statewide Elections Management System. The training and certification required under this subsection (2) shall be available to the circuit clerk, county election commissioners or any other individual designated by the board of supervisors to be responsible for implementing boundary line changes into the Statewide Elections Management System.

(3) Any governmental entity authorized to adopt, amend or change boundary lines shall immediately forward all changed boundary lines to the appropriate circuit clerk, who shall, if authorized under subsection (2), implement the boundary line changes in the Statewide Elections Management System. If the circuit clerk is not the appropriate person to implement the boundary line changes, the clerk shall immediately forward a copy of all materials to the appropriate person. Copies of any boundary line changes within the county shall be maintained in the office of the circuit clerk and made available for public inspection. No change shall be implemented or enforced until the requirements of this section have been met.

(4) Precinct boundary changes affected by the authority of this section or of any other provision of law shall not be implemented during any decade after the last day of September of the year ending in eight (8). Precinct boundaries in force and effect at such time shall remain in effect and unalterable until the last day of December in the next year ending in zero. This prohibition shall not bar the creation or modification of sub-precinct boundaries.
