If the System becomes aware that a member who is receiving an occupational, nonoccupational, or temporary disability benefit under Article 14 of the Illinois Pension Code has engaged in gainful employment or if the System becomes aware that the unmarried adult disabled child of a deceased member or annuitant is receiving a survivor's annuity or occupational death benefit under Article 14 of the Illinois Pension Code and has engaged in substantial gainful activity, then it shall immediately suspend the respective Article 14 benefit and provide the affected individual with written notice of the benefit suspension and of the individual's right to appeal the benefit suspension under subsection (e).
For purposes of this Section and Article 14 of the Illinois Pension Code, an individual engages in gainful employment and substantial gainful activity when the individual:
No member who is receiving an occupational, nonoccupational, or temporary disability benefit under Article 14 of the Illinois Pension Code and no adult disabled child who is receiving a survivor's annuity or occupational death benefit under Article 14 of the Illinois Pension Code may receive more in remuneration than the substantial gainful activity amount that is determined annually by the Commissioner of the Social Security Administration in accordance with 42 C.F.R. 423(d)(4) and found at https://www.ssa.gov/oact/cola/sga.html in any calendar quarter.
An adversely affected individual may appeal the suspension of the individual survivor's annuity, occupational death benefit, or disability benefit under this Section to the Executive Committee in the same manner as a member may appeal the disposition of a claim to the Executive Committee under Section 1540.270, except that all Petitions for Hearings and Petitions for Written Appeals must be received by the Executive Secretary of the System within 30 days after the date of the written notice described in subsection (a). If the Executive Committee determines on appeal that an individual has not engaged in gainful employment and substantial gainful activity, as described in subsection (b), while receiving a survivor's annuity, occupational death benefit, or disability benefit under Article 14 of the Illinois Pension Code, then the Executive Committee shall direct the System to reinstate the suspended benefit. If the Executive Committee determines on appeal that an individual has engaged in gainful employment or substantial gainful activity, as described in subsection (b), while receiving a survivor's annuity, occupational death benefit, or disability benefit under Article 14 of the Illinois Pension Code, then the Executive Committee shall issue a recommendation to the Board of Trustees that it terminate payment to the individual of any survivor's annuity, occupational death benefit, or disability benefit under Article 14 of the Illinois Pension Code.
If the Board of Trustees ratifies the Executive Committee's recommendation under subsection (e), that decision becomes the final administrative decision and then the System shall terminate the affected individual's survivor's annuity, occupational death benefit, or disability benefit under Article 14 of the Illinois Pension Code retroactively to the date of its initial suspension under this Section. If the Board of Trustees objects to ratification of the Executive Committee's recommendation under subsection (e), then the individual's survivor's annuity, occupational death benefit, or disability benefit under Article 14 of the Illinois Pension Code shall be reinstated retroactively to the date of benefit suspension under this Section.
