N.J. Stat. § 18A:66-111
When a majority of the members of any pension fund established pursuant to article 16 of chapter 5 of Title 18 of the Revised Statutes vote affirmatively on a referendum held pursuant to chapter 38 of the laws of 1955, any member of such fund who was in the employ of one of such boards of education on March 25, 1935 and has been continuously in the employ of one or more of such boards of education thereafter and has heretofore established credit in such pension fund for all service rendered subsequent to such date shall have the option to retire from such fund, to be exercised prior to the date of termination of the fund pursuant to referendum held in accordance with chapter 38 of the laws of 1955 and to receive during his or her natural life by way of pension 1/60 of the average annual compensation received in the last 3 years of creditable service immediately preceding his or her retirement, multiplied by the number of years of creditable service. If such option is exercised, the pension payable under this act shall be in lieu of all other rights to which the member might otherwise be entitled under said fund.
