payment of contributions for any periods of service prior to or following this
first day or the repayment of a refund.
b) A member who accepts a retirement annuity and subsequently re-enters
membership establishes a new date of membership as of that date, unless he or
she repays all annuity payments received as provided for in the statute, in
which case his or her previous date of membership is re-established.
c) For a person who, under the provisions of the Retirement Systems
Reciprocal Act [40 ILCS 5/Art. 20], repays a refund and pays for any period of
service prior to or after the service period of membership for the period of
service prior to or after the service period covered by the refund, the latest
date of membership shall be the first day of membership for the period covered
by the refund. If more than one refund is paid, it shall be the first day of
the period of membership covered by the latest of the membership periods
involved.
