(a) Any acting and contributing member of the Teachers' Retirement System of Alabama may elect to purchase credit for prior service rendered as a full-time employee in the office of a clerk of the circuit court in the State of Alabama or as a full-time employee with the Alabama State Employees Association provided the member complies with the following conditions prescribed in this section.

(b) Any employee electing to purchase credit under subsection (a) of this section shall pay to the Secretary-Treasurer of the Teachers' Retirement System within one year after October 1, 1995, a lump sum payment equal to a percentage of the current annual salary or final average compensation, whichever is greater, of the member. The applicable percentage shall be the sum of the prevailing percentage rates of employer and member contributions as required by the most recent actuarial valuation.

(c) Anything in this section to the contrary notwithstanding, a member of the Teachers' Retirement System shall not receive credit for the service where at the time of retirement he or she has credit or is entitled to receive any benefits whatsoever for the same service under any other retirement or pension plan which is wholly or partly funded from public funds; provided, however, that nothing herein shall be construed to apply to participation in the federal Social Security program. In the event of disqualification of the service credit, contributions made under this section by the member shall be refunded to him or her.
