Any person who knowingly makes a false statement, or falsifies or permits to be falsified any record or records of this retirement fund in any attempt to defraud such fund as a result of such act, is guilty of theft, and is punishable therefor under the laws of the state of North Dakota. Should any change or error in records result in any person receiving from the fund more or less than that person would have been entitled to receive had the records been correct, then, on the discovery of any such error, the 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 such person was correctly entitled is paid.
