If any change or error in the records of the system or any participating unit results in any person receiving from the system less than the person would have been entitled to receive had the records been correct, the executive director must correct the error and, as far as practicable, adjust the payment to provide the person the amount to which the person is correctly entitled.
If any change or error in the records of the system or any participating unit results in any person receiving from the system more than the person would have been entitled to receive had the records been correct, the executive director must correct the error and, as far as practicable, recover the overpayment to reflect the amount to which the person is correctly entitled. The board shall promulgate rules, pursuant to chapter 1-26, concerning the methods by which an overpayment must be repaid, including an actuarial equivalent. The recovery of an overpayment is limited to the amount attributable to any error that occurred during the six-year period immediately before the discovery of the error. This limitation does not apply in the case of fraud, intentional misrepresentation, material omission, or other fault on the part of a member or beneficiary.
Upon request, a member of the system may, during business hours, inspect any file directly relating to the member and request the correction of any alleged errors in the file.
