O.C.G.A. § 21-2-432

After each elector has been admitted to vote, his or her voter’s certificate shall be inserted in the binder provided therefor by the registrars, and known as the “voter’s certificate binder,” and such voter’s certificates so bound shall constitute the official list of electors voting at such primary or election. All voter’s certificates prepared by persons applying to vote whose applications to vote are refused by the poll officers shall be separately preserved and returned to the superintendent with the other papers.
