(1) Any party or party-in-interest adversely affected or aggrieved by a decision or order issued pursuant to one of the Acts over which the Board has appellate jurisdiction may appeal a decision or order of an administrative law judge or deputy commissioner to the Board by filing a notice of appeal pursuant to this subpart. (See § 802.205(b) and (c) for exceptions to this general rule.) A party who files a notice of appeal shall be deemed the petitioner. The Director, OWCP, when acting as a representative of the Special Fund established under the Longshore and Harbor Workers' Compensation Act or the Black Lung Disability Trust Fund established by the Black Lung Benefits Act, or, when appealing a decision or order which affects the administration of one of the Acts, shall be considered a party adversely affected.

(2) When a decision or order is favorable to a party (i.e., the prevailing party), the prevailing party may file a cross-appeal pursuant to § 802.205(b) to challenge any adverse findings of fact or conclusions of law in the same proceeding.
