Retirement Annuities and Survivors Annuities - Guarantees.
(a) This amendatory Act of 1975 (P.A. 79-782) shall not be applied to
deprive any person or his survivor of eligibility for an annuity or to reduce
the annuity or to deprive such person of rights to which he or his survivor
would have been entitled under the provisions of Article 20 which were in
effect immediately prior to September 5, 1975, if he was an employee
immediately prior to that date.
(b) If the combined retirement annuity benefits provided under Public
Act 79-782 are less than the combined retirement annuity benefits that would
have been payable under the alternative formula of Section 20-122, the system
under which retirement would have occurred, as provided by Section 20-122,
shall increase the proportional retirement annuity by an amount equal to the
difference.
(c) Subsection (b) of this Section does not apply to the retirement
annuity benefits payable under the self-managed plan established under Section
