43 CFR § 4.624 - When may further proceedings be held?
(a) Ordinarily, the determination of an award will be made on the basis of the written record. However, the adjudicative officer may order further proceedings, which will be held only when necessary for full and fair resolution of the issues and will be conducted as promptly as possible.
(b) The adjudicative officer may order further proceedings on his or her own initiative or in response to a request by you or by the Department or other agency. A request for further proceedings under this section must:
(1) Identify the information sought or the disputed issues; and
(2) Explain why the additional proceedings are necessary to resolve the issues.
(c) As to issues other than substantial justification (such as your eligibility or substantiation of fees and expenses), further proceedings under this section may include an informal conference, oral argument, additional written submissions, pertinent discovery, or an evidentiary hearing.
(d) The adjudicative officer will determine whether the position of the Department or other agency was substantially justified based on the administrative record of the adversary adjudication as a whole.
