ART. 302. Appeal. — Decisions, awards, or orders of the Labor Arbiters or compulsory arbitrators are final and executory unless appealed to the Commission by any or both of the parties within ten (10) days from receipt of such awards, orders, or decisions. Such appeal may be entertained only on any of the following grounds: If there is prima facie evidence of grave abuse of discretion on the part of the Labor Arbiter or compulsory arbitrator; If the decision, order, or award was secured through fraud or coercion, including graft and corruption; and If made purely on question of law. To discourage frivolous or dilatory appeals, the Commission or the Labor Arbiters shall impose reasonable penalty, including fines or censure, upon the erring parties. In all cases, the appellant shall furnish a copy of the memorandum of appeal to the other party who shall file an answer not later than ten (10) days from receipt thereof. The Commission shall decide all cases within twenty (20) working days from receipt of the answer of the appellee; otherwise, the appealed decision or award shall be considered affirmed. The decision of the Commission shall be final and unappealable, except in the following cases: By certiorari to the Supreme Court on question of law; and Where the case involves national interest, in which case it may be appealed to the President of the Philippines upon recommendation of the Secretary of Labor within 10 days from receipt of such decision by the appealing party.
