The Appeals Board may permit the submission to be further supplemented by oral argument (transcribed if requested), and by briefs arranged in accordance with COMAR 21.10.05.12.S ubmission of an appeal without hearing does not relieve the parties from the necessity of proving the facts supporting their claims or defenses.
