         (iii)   Under no circumstances shall the purchase of credit by a beneficiary or estate pursuant to subparagraph (i) of this paragraph result in any benefit or any increase in benefit becoming payable pursuant to a presumptive retirement provision, or provision for payment of a death benefit equal to a pension reserve.
      (11)   (i)   A member of NYCERS in city-service or a member of BERS in education service who:
            (A)   meets the requirements of paragraph one of this subdivision; and

            (C)   otherwise is eligible to retire for service or otherwise would be eligible to retire for service if he or she were permitted to purchase credit for such part-time service; and
            (D)   submits to the appropriate retirement system a written request to purchase credit for a lump sum amount for any such period or periods of previous part-time service, in which request it is alleged that he or she is physically or mentally incapacitated for the performance of duty shall be entitled to a medical examination which shall be performed by the medical board of such retirement system.
         (ii)   Notwithstanding any other provision of law to the contrary, if such medical examination shows that any such member who meets the requirements of subparagraph (i) of this paragraph eleven is physically or mentally incapacitated for the performance of duty, the medical board shall so report to the executive director of such retirement system, and such member in city-service or education service shall be permitted to purchase credit for such period or periods of previous part-time service by paying a lump sum amount computed in accordance with the applicable provisions governing the purchase of credit for previous service, provided that such member shall both (A) actually retire for service effective not later than sixty days after being notified by the retirement system that he or she is eligible to purchase credit for such service pursuant to this paragraph, and (B) complete payment for such purchase within such sixty-day period.
      (12)   Notwithstanding any other provision which requires a person to be in city-service in order to become a member of NYCERS, or in education service in order to become a member of BERS, and notwithstanding any other provision of law to the contrary, a person who:
         (i)   was paid on the payroll in active part-time service on May thirty-first, nineteen hundred eighty-eight; and
         (ii)   separated from part-time service (other than as a result of dismissal on charges or forfeiture of office) subsequent to May thirty-first, nineteen hundred eighty-eight and prior to August first, nineteen hundred ninety-two, and has not returned to active service; and
         (iii)   was otherwise eligible to become a member of NYCERS or BERS based upon such part-time service; and
         (iv)   did not file an application to become a member of such retirement system prior to such separation from service shall be permitted to become a member of such retirement system by filing an application for membership with such system during the window period, provided that such person shall otherwise be eligible pursuant to paragraph seven of this subdivision to retire for service and shall actually retire for service pursuant to such paragraph seven during the window period with an effective date of retirement during the window period.

      (3)   The board of trustees of NYCERS and the retirement board of BERS shall have the authority to adopt reasonable rules for prorating the credit for part-time city-service or part-time education service rendered in part-time per annum job titles for which it is difficult to determine the number of hours actually worked, including, but not limited to, such titles as New York city tax commissioner, New York city planning commissioner and New York city councilmanic aide. Such rules shall, to the extent possible, grant service credit based on the number of hours actually worked in such titles.
   d.   Purchase of credit for previous part-time service.
      (1)   Except as provided in paragraphs two and three of this subdivision, and subject to the provisions of paragraphs six through eleven of subdivision b of this section, where those provisions are applicable, the purchase of credit for previous part-time service by a member of NYCERS or BERS shall be governed by all of the applicable provisions which otherwise would govern the purchase of credit for pre-membership service by such member.
      (2)   (i)   Notwithstanding any other provision of law to the contrary, a member of NYCERS may purchase credit for previous part-time education service which was rendered prior to the expiration of the window period (as defined in paragraph twenty-two of subdivision a of this section), except that such member may not purchase credit for any such part-time education service rendered prior to the expiration of the window period which was rendered during a payroll period in which such member also rendered city-wide for which he or she has earned or is eligible to earn service credit.
