O.C.G.A. § 14-3-1022: Voting by classes of members.

If the articles or bylaws provide for voting by classes of members, then unless the articles or bylaws provide otherwise:

(1) The members of a class are entitled to vote as a class on a proposed amendment to the bylaws if the amendment would change the rights of that class as to voting in a different manner than such amendment would affect another class or members of another class;

(2) If a class is to be divided into two or more classes as a result of an amendment to the bylaws, the amendment must be approved by the members of each class that would be created by the amendment; and

(3) If a class vote is required to approve an amendment to the bylaws, the amendment must be approved by the members of the class by two-thirds of the votes cast by the class or a majority of the voting power of the class, whichever is less.
