The CEO must waive the right to recover the proportion of a debt that is attributable solely to an administrative error made by the Agency if the debtor received in good faith the payment or payments that gave rise to that proportion of the debt and:
(a) the debt is not raised within 6 weeks from the first payment that caused the debt; or
(b) if the debt arose because a person has complied with a notification obligation--the debt is not raised within 6 weeks from the end of the notification period;
Note: This section does not allow waiver of a part of a debt that was
caused partly by administrative error and partly by one or more other factors
(such as error by the debtor).
