The following are the types of decisions which may be made by a board when a claim for classification in Class 1-A-0 or Class 1-0 has been considered.

(a) Decision to grant a claim for classification in Class 1-A-0 or Class 1-0, as requested, based on a determination that the truth or sincerity of the registrant's claim is not refuted by any information contained in the registrant's file or obtained during his personal appearance.

(b) Decision to deny a claim for classification in Class 1-A-0 or Class 1-0 based on all information before the board, and a finding that such information fails to meet the tests specified in § 1636.3 or 1636.4 of this part. If supported by information contained in the registrant's file or obtained during his personal appearance the board may find that the facts presented by the registrant in support of his claim are untrue.
