22 CFR 17.3 - Fault.
A recipient of an overpayment is without fault if he or she performed no act of commission or omission that resulted in the overpayment. The fact that the Department of State or other agency may have been at fault in initiating an overpayment will not necessarily relieve the individual from liability.
(1) Whether payment resulted from the individual's incorrect but not necessarily fraudulent statement, which he/she should have known to be incorrect;
(2) Whether payment resulted from the individual's failure to disclose material facts in his/her possession which he/she should have known to be material; or
(b) Mitigation factors. The individual's age, physical and mental condition or the nature of the information supplied to him or her by the Department of State or a Federal agency may mitigate against finding fault if one or more contributed to his or her submission of an incorrect statement, a statement which did not disclose material facts in his or her possession, or his or her acceptance of an erroneous overpayment.
