(a) The members of the Board of Commissioners for each judicial circuit shall be elected by the members of the State Bar who maintain their principal office in such circuit; provided, however, that for the Tenth Circuit, each commissioner shall be elected by the lawyers who maintain their principal office in the portion of the circuit outside the Bessemer Cut-off electoral district and each commissioner for the Bessemer Cut-off electoral district shall be elected by the lawyers who maintain their principal office in that portion of the circuit inside the Bessemer Cut-off electoral district. Such election shall be by secret ballot, mailed or delivered to the State Bar headquarters by a date established by the Board of Commissioners. Nothing contained in this article shall prohibit the election of the president of the State Bar as provided in this chapter, who shall be a bona fide resident of any judicial circuit of this state and who shall be ex officio president of the Board of Commissioners in case he or she is not already a member of said board. If hereafter additional judicial circuits are constituted, each such additional circuit shall be entitled to a commissioner or commissioners on said board, as provided by Section 34-3-40. There shall be an annual election for the purpose of selecting successors to the commissioners whose terms expire. The board shall prescribe rules and regulations in regard to such annual elections and establishment of additional commissioner positions as required, not in conflict with the provisions of this article. The board shall, in accordance with its rules, give at least 60 days' notice of the time for holding the election each year. Such annual election shall be held on the first Tuesday in June of each year and continue for one week. The term of each commissioner shall be three years from July first following his or her election, except initial terms prescribed by the Board of Commissioners pursuant to subdivision (b)(2) of this section.
