(40 ILCS 5/8-167) (from Ch. 108 1/2, par. 8-167)
    Sec. 8-167. Restoration of rights. An employee who has withdrawn as a refund the amounts credited for annuity purposes, and who (i) re-enters service of the employer and serves for periods comprising at least 90 days after the date of the last refund paid to him or (ii) has completed at least 2 years of service under a participating system (as defined in the Retirement Systems Reciprocal Act) other than this Fund after the date of the last refund, shall have his annuity rights restored by compliance with the following provisions:
        (a) After that 90 day or 2 year period, whichever applies, he shall repay in full to the
    
fund, while in service, all refunds received, together with interest at the effective rate from the dates of refund to the date of repayment.
        (b) If payment is not made in a single sum, the repayment may be made in installments by
    
deductions from salary or otherwise in such manner and amounts and manner as the board, by rule, may prescribe, with interest at the effective rate accruing on unpaid balances.
        (c) If the employee withdraws from service or dies in service before full repayment is
    
made, service credit shall be restored in accordance with Section 8-230.3(b).
        (d) If the employee repays the refund while participating in a participating system (as
    
defined in the Retirement Systems Reciprocal Act) other than this Fund, the service credit restored must be used for a proportional annuity calculated in accordance with the Retirement Systems Reciprocal Act. If not so used, the restored service credit shall be forfeited and the amount of the repayment shall be refunded, without interest.
    This Section applies also to any person who received a refund from any annuity and benefit fund or pension fund which was merged into and superseded by the annuity and benefit fund provided for in this Article on or after December 31, 1959. Upon repayment such person shall receive credit for all annuity purposes in the annuity and benefit fund provided for in this Article for the period of service covered by the repayment.
    The amount of refund repayment is considered as salary deductions for age and service annuity and widow's annuity purposes in the case of a male person. In the latter case the amount of refund repayment is allocated in the applicable proportion for age and service and widow's annuity purposes. Such person shall also be credited with city contributions for age and service annuity, and widow's annuity if a male employee, in the amount which would have been credited and accrued if such person had been a participant in and contributor to the annuity and benefit fund provided for in this Article during the period of such service on the basis of his salary during such period.
