Retirement and Social Security Law for “all members who join or rejoin a public retirement system of the state on or after July first, nineteen hundred seventy-six”. On July 1,1980 section B20-41.2 of the Administrative Code was amended to provide that any contributor in membership service on June 30, 1972 could elect to become a 20-year pension plan contributor by filing an application between July 1, 1980 and June 30, 1981. (Administrative Code, § B20-41.2, subd a, par [1], cl [c].) Petitioner filed such an application on February 14, 1981. The retirement system denied the application on the ground that although petitioner was an in-service member on June 30, 1972, she was ineligible for Plan A since she had not returned to membership in the system within five years after resigning and withdrawing her contributions to the annuity savings fund. Special Term granted the CPLR article 78 petition, finding that petitioner, by having been an in-service member on June 30,1972, fulfilled the qualifications for transfer to Plan A pursuant to section B20-41.2 (subd a, par [1], cl [c]). This was error and we reverse. Since the enactment of article 14 of the Retirement and Social Security Law in 1976, applicable to all public retirement systems of the State, the New York City Teachers’ Retirement System is divided into three tiers (see
Capital Dist. Regional Off-Track Betting Corp. v Levitt, 65 AD2d 842 ), within which are several benefit plans. The 20-year pension plan, Plan A, to which petitioner sought transferral, is part of Tier I, which is applicable to members who joined on or before June 30, 1973. (Administrative Code, §§ B20-41.2, B20-41.3.) The Co-Esc Plan, of which she necessarily became a member on rejoining the system in 1978, is the Tier III pension plan. From time to time the Legislature has authorized for a limited period a member in Plan B who otherwise qualified to elect to transfer to Plan A. (Administrative Code, § B20-41.2, subd a, par [1], els [b], [c].) No parallel legislation, however, has ever been enacted permitting a contributing member of the Teachers’ Retirement System to transfer between tiers. Review of the legislative history reveals that section B20-41.2 (subd a, par [1], cl [cl) was intended to permit Plan B members at their option to transfer to Plan A, but within Tier I. “Many members of the New York City Teachers’ Retirement System will be deprived of the opportunity to retire under the 20 Year Pension Plan although they have fulfilled all of the requirements for such Retirement Benefits. The law that established the 20 Year Pension Plan required the teacher to elect to join the plan within two years. If the teacher failed to make such a timely election, they were automatically placed in an inferior Pension Plan that requires them to serve for a longer period of time and receive a smaller pension. Most of the teachers who failed to make the timely election required to join the 20 Year Pension Plan, failed to do so for reasons over which they had no control. Some teachers were in the Armed Forces and some others were on Maternity and Child-Care Leaves during the time that they were allowed to select a better plan. The purpose of the original legislation was not to penalize the members of the Retirement System, however, in many cases, circumstances beyond the control of the member made it impossible to make a timely election. This legislation would correct the injustice that occurred by reopening for one year the opportunity to now elect the 20 Year Plan for those members of the system who failed to make a timely election previously.” (Memorandum by Assemblyman Lentol, sponsor of L 1980, ch 860, enacting Administrative Code, § B20-41.2, subd a, par [1], cl [c]; NY Legis Ann, 1980, p 368.) Moreover, the Governor’s approval memorandum of the same bill stated in pertinent part: “This bill permits certain members of the New York City Teachers’ Retirement System in service on June 30, 1972, who had an opportunity to elect during a two-year period commencing July 1, 1970, and ending June 30, 1972 to join the 20-year pension plan enacted in 1970, to now
