(a) General rule. The determination of a recommended award shall be made by the administrative law judge on the basis of the written record of the adversary adjudication, including any supporting affidavits submitted in connection with the application, unless, on the motion of either the applicant or Board counsel, or sua sponte, the administrative law judge or the Board orders further proceedings to amplify the record such as an informal conference, oral argument, additional written submissions, or an evidentiary hearing. Such further proceedings shall be held only when necessary for full and fair resolution of the issues arising from the application and shall be conducted promptly and expeditiously.

(b) Request for further proceedings. A request for further proceedings under this section shall specifically identify the information sought or the issues in dispute and shall explain why additional proceedings are necessary.

(c) Hearing. The administrative law judge shall hold an oral evidentiary hearing only on disputed issues of material fact which cannot be adequately resolved through written submissions.
