Section 5-156c - Erroneous payments; adjustment; waiver of repayment; regulations(a) Should any change or error in records result in any member or beneficiary receiving from any retirement system administered by the State Employees Retirement Commission more or less than he would have been entitled to receive had the records been correct, then upon discovery of any such error the Retirement Commission shall notify the member or beneficiary affected and correct the same, and as far as practicable shall adjust the payments in such manner that the actuarial equivalent of the benefit to which such member or beneficiary was correctly entitled shall be paid, provided if such change or error results in any member or beneficiary receiving less than he would have been eligible to receive, such member or beneficiary may elect to have such benefit paid in a single payment.(b) If a member or beneficiary has been overpaid through no fault of his own, and he could not reasonably have been expected to detect the error, the Retirement Commission may waive any repayment which it believes would cause hardship.(c) The Retirement Commission shall adopt regulations in accordance with the provisions of chapter 54 establishing criteria for the waiver of repayment.Conn.
