N.Y.C. Admin. Code § 13-265: § 13-265 Protection against fraud or mistake.

Any person who shall knowingly make any false statement, or shall falsify or permit to be falsified any record or records of this pension fund, shall be guilty of a misdemeanor. Should any change of error in records result in any member or beneficiary receiving from the pension fund more or less than he or she would have been entitled to receive otherwise, on the discovery of any such error such board shall correct such error, and, as far as practicable, shall adjust the payments in such a manner that the actuarial equivalent of the benefit to which he or she was entitled shall be paid.
