(a) Upon the application of a member or his employer, any active member in state service who became a member of the system before July 1, 2007, and who has at least four (4) years of membership service credit, or any active member in state service who became a member of the system on or after July 1, 2007, who has at least eight (8) years of membership service credit, may be retired by the board of trustees on the first of the month following the date of filing the application on a disability retirement allowance, but in no event shall the disability retirement allowance begin before termination of state service, provided that the medical board, after an evaluation of medical evidence that may or may not include an actual physical examination by the medical board, certifies that the member is mentally or physically incapacitated for the further performance of duty, that the incapacity is likely to be permanent, and that the member should be retired; however, the board of trustees may accept a disability medical determination from the Social Security Administration in lieu of a certification from the medical board. If a member who has been approved for a disability retirement allowance does not terminate state service within ninety (90) days after approval, the disability retirement and the application for disability retirement shall be void. For the purposes of disability determination, the medical board shall apply the following definition of disability: the inability to perform the usual duties of employment or the incapacity to perform such lesser duties, if any, as the employer, in its discretion, may assign without material reduction in compensation, or the incapacity to perform the duties of any employment covered by the Public Employees’ Retirement System (Section 25-11-101 et seq.) that is actually offered and is within the same general territorial work area, without material reduction in compensation. The employer shall be required to furnish the job description and duties of the member. The employer shall further certify whether the employer has offered the member other duties and has complied with the applicable provisions of the Americans With Disabilities Act in affording reasonable accommodations that would allow the employee to continue employment.

(b) Any member applying for a disability retirement allowance must provide sufficient objective medical evidence in support of his or her claim. All disability determinations, whether the initial examination or reexamination, shall be based on objective medical evidence. “Objective medical evidence” means reports of examinations or treatments; medical signs that are anatomical, physiological, or psychological abnormalities that are observed and documented by medical professionals; psychiatric signs that are medically demonstrable phenomena indicating specific abnormalities of behavior, affect, thought, memory, orientation, or contact with reality; or laboratory findings that are anatomical, physiological, or psychological phenomena that are shown by medically acceptable laboratory diagnostic techniques, including, but not limited to, chemical tests, electrocardiograms, electroencephalograms, X-rays, and psychological tests. Nonmedical information shall not be considered objective medical evidence.

(c) Any inactive member who became a member of the system before July 1, 2007, with four (4) or more years of membership service credit, or any inactive member who became a member of the system on or after July 1, 2007, with eight (8) or more years of membership service credit, who has withdrawn from active state service, is not eligible for a disability retirement allowance unless the disability occurs within six (6) months of the termination of active service and unless satisfactory proof is presented to the board of trustees that the disability was the direct cause of withdrawal from state service. Application for a disability retirement allowance must be filed within one (1) year of termination from active service. This period may be extended by an additional year if it can be factually demonstrated to the satisfaction of the board of trustees that throughout the initial one-year period the member was incapable of applying for benefits by reason of mental or physical impairment as certified by a medical doctor.

(d) Any member who is or becomes eligible for service retirement benefits under Section 25-11-111 while pursuing a disability retirement allowance under this section or Section 25-11-114 may elect to receive a service retirement allowance pending a final determination on eligibility for a disability retirement allowance or withdrawal of the application for the disability retirement allowance. In such a case, an application for a disability retirement allowance must be on file with the system before the beginning of a service retirement allowance. If the application is approved, the option selected and beneficiary designated on the retirement application shall be used to determine the disability retirement allowance. If the application is not approved or if the application is withdrawn, the service retirement allowance shall continue to be paid in accordance with the option selected. No person may apply for a disability retirement allowance after the person begins to receive a service retirement allowance.

(e) If the medical board certifies that the member is not mentally or physically incapacitated for the future performance of duty, the member may request, within sixty (60) days, a hearing before the hearing officer as provided in Section 25-11-120. All hearings shall be held in accordance with rules and regulations adopted by the board to govern those hearings. The hearing may be closed upon the request of the member.

(f) The medical board may request additional medical evidence and/or other physicians to conduct an evaluation of the member’s condition. If the medical board requests additional medical evidence and the member refuses the request, the application shall be considered void.

(2) Allowance on disability retirement.

(a) Upon retirement for disability, an eligible member shall receive a retirement allowance if he has attained the age of sixty (60) years.

(b) Except as provided in paragraph (c) of this subsection (2), an eligible member who is retired for disability and who has not attained sixty (60) years of age shall receive a disability benefit as computed in Section 25-11-111(d), which shall consist of:

(i) A member’s annuity, which shall be the actuarial equivalent of his accumulated contributions at the time of retirement; and

(ii) An employer’s annuity equal to the amount that would have been payable as a retirement allowance for eligible creditable service if the member had continued in service to the age of sixty (60) years, which shall apply to the allowance for disability retirement paid to retirees receiving such allowance upon and after April 12, 1977. This employer’s annuity shall be computed on the basis of the average “earned compensation” as defined in Section 25-11-103.

(c) For persons who become members after June 30, 1992, and for active members on June 30, 1992, who elect benefits under this paragraph (c) instead of those provided under paragraph (b) of this subsection (2), the disability allowance shall consist of two (2) parts: a temporary allowance and a deferred allowance.

(d) The member may elect to receive the actuarial equivalent of the disability retirement allowance in a reduced allowance payable throughout life under any of the provisions of the options provided under Section 25-11-115.

(e) If a disability retiree who has not selected an option under Section 25-11-115 dies before being repaid in disability benefits the sum of his total contributions, then his named beneficiary shall receive the difference in cash, which shall apply to all deceased disability retirees from and after January 1, 1953.

(3) Reexamination of retirees retired on account of disability. Except as otherwise provided in this section, once each year during the first five (5) years following retirement of a member on a disability retirement allowance, and once in every period of three (3) years thereafter, the board of trustees may, and upon his application shall, require any disability retiree who has not yet attained the age of sixty (60) years or the termination age of the temporary allowance under subsection (2)(c) of this section to undergo a medical examination, the examination to be made at the place of residence of the retiree or other place mutually agreed upon by a physician or physicians designated by the board. The board, however, in its discretion, may authorize the medical board to establish reexamination schedules appropriate to the medical condition of individual disability retirees. If any disability retiree who has not yet attained the age of sixty (60) years or the termination age of the temporary allowance under subsection (2)(c) of this section refuses to submit to any medical examination provided in this section, his allowance may be discontinued until his withdrawal of that refusal; and if his refusal continues for one (1) year, all his rights to a disability benefit shall be revoked by the board of trustees.

(4) If the medical board reports and certifies to the board of trustees, after a comparable job analysis or other similar study, that the disability retiree is engaged in, or is able to engage in, a gainful occupation paying more than the difference between his disability allowance, exclusive of cost-of-living adjustments, and the average compensation, and if the board of trustees concurs in the report, the disability benefit shall be reduced to an amount that, together with the amount earnable by him, equals the amount of his average compensation. If his earning capacity is later changed, the amount of the benefit may be further modified, provided that the revised benefit shall not exceed the amount originally granted. A retiree receiving a disability benefit who is restored to active service at a salary less than the average compensation shall not become a member of the retirement system.

(5) If a disability retiree under the age of sixty (60) years or the termination age of the temporary allowance under subsection (2)(c) of this section is restored to active service at a compensation not less than his average compensation, his disability benefit shall end, he shall again become a member of the retirement system, and contributions shall be withheld and reported. Any such prior service certificate, on the basis of which his service was computed at the time of retirement, shall be restored to full force and effect. In addition, upon his later retirement he shall be credited with all creditable service as a member, but the total retirement allowance paid to the retired member in his previous retirement shall be deducted from his retirement reserve and taken into consideration in recalculating the retirement allowance under a new option selected.

(6) If following reexamination in accordance with the provisions contained in this section, the medical board determines that a retiree retired on account of disability is physically and mentally able to return to the employment from which he is retired, the board of trustees, upon certification of those findings from the medical board, shall, after a reasonable period of time, terminate the disability allowance, whether or not the retiree is reemployed or seeks that reemployment. In addition, if the board of trustees determines that the retiree is no longer sustaining a loss of income as established by documented evidence of the retiree’s earned income, the eligibility for a disability allowance shall terminate and the allowance terminated within a reasonable period of time. If the retirement allowance is terminated under the provisions of this section, the retiree may later qualify for a retirement allowance under Section 25-11-111 based on actual years of service credit plus credit for the period during which a disability allowance was paid.

(7) Any current member as of June 30, 1992, who retires on a disability retirement allowance after June 30, 1992, and who has not elected to receive benefits under subsection (2)(c) of this section, shall relinquish all rights under the Age Discrimination in Employment Act of 1967, as amended, with regard to the benefits payable under this section.
