Decisions, awards, or orders of the Labor Arbiter are final and executory unless appealed to the Commission by any or both parties within ten (10) calendar days from receipt of such decisions, awards, or orders. Such appeal may be entertained only on any of the following grounds:
(a) If there is prima facie evidence of abuse of discretion on the part of the Labor Arbiter;
(b) If the decision, order or award was secured through fraud or coercion, including graft and corruption;
(c) If made purely on questions of law; and
(d) If serious errors in the findings of facts are raised which would cause grave or irreparable damage or injury to the appellant.
In case of a judgment involving a monetary award, an appeal by the employer may be perfected only upon the posting of a cash or surety bond issued by a reputable bonding company duly accredited by the Commission in the amount equivalent to the monetary award in the judgment appealed from.
In any event, the decision of the Labor Arbiter reinstating a dismissed or separated employee, insofar as the reinstatement aspect is concerned, shall immediately be executory, even pending appeal. The employee shall either be admitted back to work under the same terms and conditions prevailing prior to his dismissal or separation or, at the option of the employer, merely reinstated in the payroll. The posting of a bond by the employer shall not stay the execution for reinstatement provided herein.
To discourage frivolous or dilatory appeals, the Commission or the Labor Arbiter shall impose reasonable penalty, including fines or censures, 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) calendar days from receipt thereof. The Commission shall decide all cases within twenty (20) calendar days from receipt of the answer of the appellee.
The decision of the Commission shall be final and executory after ten (10) calendar days from receipt thereof by the parties.
Any law enforcement agency may be deputized by the Secretary of Labor and Employment or the Commission in the enforcement of decisions, awards or orders.
