(3) REEXAMINATION OF BENEFICIARIES RETIRED ON ACCOUNT OF DISABILITY. Once each year during the first five years following the retirement of a member on a disability retirement allowance and once every three-year period thereafter, the Board of Control may, and upon his or her application shall, require any disability beneficiary who has not yet attained age 60 if the beneficiary is a Tier I plan member or age 62 if the beneficiary is a Tier II plan member to undergo a medical examination, such examination to be made at the place of residence of such beneficiary or other place mutually agreed upon by a physician or physicians of, or designated by, the medical board. Should any disability beneficiary who has not yet attained age 60, if the beneficiary is a Tier I plan member or age 62 if the beneficiary is a Tier II plan member, refuse to submit to such medical examination, his or her allowance may be discontinued until his or her withdrawal of such refusal, and, should his or her refusal continue for one year, all his or her rights in and to his or her pension may be revoked by the Board of Control; provided, that these requirements relative to the medical examination shall not apply in the case of a state policeman retired for disability and who has attained age 52 if he or she is a Tier I plan member or in the case of a state policeman or a correctional officer, firefighter, or law enforcement officer as defined in Section
36-27-59 with at least 10 years of creditable service as a correctional officer, firefighter, or law enforcement officer retired for disability who has attained age 56 if he or she is a Tier II plan member. Should the medical board report and certify to the Board of Control that a disability beneficiary who is a Tier I plan member is engaged in or is able to engage in a gainful occupation paying more than the difference between his or her retirement allowance and his or her average final compensation and should the Board of Control concur in such report, then the amount of his or her pension shall be reduced to an amount which, together with his or her annuity and the amount earnable by him or her shall equal the amount of his or her average final compensation. Should his or her earning capacity be later changed, the amount of his or her pension may be further modified; provided, that the new pension shall not exceed the amount of the pension originally granted nor an amount which, when added to the amount earnable by the beneficiary, together with this annuity exceeds the amount of his or her average final compensation.
Should the medical board report and certify to the Board of Control that a disability beneficiary who is a Tier II plan member has the capacity to engage in regular and substantial gainful employment, the Board of Control shall discontinue the beneficiary's retirement allowance until the beneficiary is otherwise eligible for service retirement.
