36.1. In the event any change or error in the records of the Retirement Plan results in any person receiving from the Plan more or less than he would have been entitled to receive had the records been correct, the Retirement Board shall correct such error and, as far as practicable, shall adjust subsequent payments in such manner that the actuarial equivalent of the benefits to which the said person was correctly entitled shall be paid. In the event of overpayment to any person the Board may take legal action, if necessary, to recover such overpayment.
