(a) On and after July 1, 1980, the employer shall pay to the fund on each and every payroll period employee contributions on behalf and to the credit of such judges of the superior court in an amount equal to the amount which would be paid to the annuity savings fund pursuant to Code Section 47-2-54 if the judge of the superior court were a member of the Employees' Retirement System of Georgia. Such judges of the superior courts shall continue to have deducted from their state salaries the additional amount of employee contributions required by this chapter.

The monthly retirement benefit of each heretofore retired senior judge shall be increased accordingly, effective July 1, 1980.

(d) All members shall retain, have, and be subject to all other rights, privileges, obligations, and duties provided for by other provisions of this chapter; and all such other provisions shall remain of full force and effect with respect to any matter not specifically provided for in this Code section.
