(1) An applicable statute authorizes or requires the agency to consider waiver of the indebtedness involved, the debtor requests waiver of the indebtedness, and the waiver determination turns on an issue of credibility or veracity; or

(2) Unless otherwise required by law, a hearing under this section is not required to be a formal evidentiary-type hearing, although significant matters discussed at the hearing should be documented. See 31 CFR 901.3(e)(1). Such hearing may be an informal discussion/interview with the debtor, face-to-face meeting between debtor and cognizant NASA personnel, or written formal submission by the debtor and response by the NASA cognizant personnel with an opportunity for oral presentation. The hearing will be conducted before or in the presence of an official as designated by the NASA General Counsel on a case-by-case basis. The hearing is not an adversarial adjudication and need not take the form of an evidentiary hearing. However, depending on the particular facts and circumstances, the hearing may be analogous to a fact-finding proceeding with oral presentations; or an informal meeting with or interview of the employee; or formal written submissions, with an opportunity for oral presentation, and decision based on the available written record. Ordinarily, hearings may consist of informal conferences before the hearing official in which the employee and Agency officials will be given full opportunity to present evidence, witnesses, and argument. The employee may represent himself or herself or be represented by an individual of his or her choice at no cost to the United States. The hearing official must maintain or provide for a summary record of the hearing provided under this subpart. The decision of the reviewing/hearing official should be communicated in writing (no particular form is required) to the affected parties and will constitute the final administrative decision of the Agency.
