§ 617. Recalculation of benefits. a. Notwithstanding any other
provision of law, any person who has retired pursuant to the provisions
of article fourteen of this chapter on or before August thirty-first,
nineteen hundred eighty-three, whether for service retirement or for
ordinary or accidental disability retirement, may elect to have his or
her retirement benefits recalculated pursuant to this article, from such
person's date of retirement; provided, however, such person was not
employed in a position excluded from the application of this article by
paragraphs one through five of subdivision a of section six hundred of
this article. The recalculation of benefits shall be based upon the
option selection originally filed for retirement.

December thirty-first, nineteen hundred ninety-nine, file a request for
such recalculation with the appropriate retirement system in the form
