Generally, the arbitral award of CIAC is final and may not be appealed except on questions of law.
Executive Order (E.O.) No. 1008[22] vests upon the CIAC original and exclusive jurisdiction over disputes arising from, or connected with, contracts entered into by parties involved in construction in the Philippines
In Hi-Precision Steel Center, Inc. v. Lim Kim Steel Builders, Inc.,[24] we explained raison d’ etre for the rule on finality of the CIAC’s arbitral award in this wise:
Voluntary arbitration involves the reference of a dispute to an impartial body, the members of which are chosen by the parties themselves, which parties freely consent in advance to abide by the arbitral award issued after proceedings where both parties had the opportunity to be heard. The basic objective is to provide a speedy and inexpensive method of settling disputes by allowing the parties to avoid the formalities, delay, expense and aggravation which commonly accompany ordinary litigation, especially litigation which goes through the entire hierarchy of courts. Executive Order No. 1008 created an arbitration facility to which the construction industry in thePhilippines
Aware of the objective of voluntary arbitration in the labor field, in the construction industry, and in any other area for that matter, the Court will not assist one or the other or even both parties in any effort to subvert or defeat that objective for their private purposes. The Court will not review the factual findings of an arbitral tribunal upon the artful allegation that such body had "misapprehended the facts" and will not pass upon issues which are, at bottom, issues of fact, no matter how cleverly disguised they might be as "legal questions." The parties here had recourse to arbitration and chose the arbitrators themselves; they must have had confidence in such arbitrators. x x x[25] (Citation omitted)
Thus, in cases assailing the arbitral award rendered by the CIAC, this Court may only pass upon questions of law. Factual findings of construction arbitrators are final and conclusive and not reviewable by this Court on appeal. This rule, however, admits of certain exceptions.
In Spouses David v. Construction Industry and Arbitration Commission,[26] we laid down the instances when this Court may pass upon the factual findings of the CIAC, thus:
We reiterate the rule that factual findings of construction arbitrators are final and conclusive and not reviewable by this Court on appeal, except when the petitioner proves affirmatively that: (1) the award was procured by corruption, fraud or other undue means; (2) there was evident partiality or corruption of the arbitrators or of any of them; (3) the arbitrators were guilty of misconduct in refusing to postpone the hearing upon sufficient cause shown, or in refusing to hear evidence pertinent and material to the controversy; (4) one or more of the arbitrators were disqualified to act as such under section nine of Republic Act No. 876 and willfully refrained from disclosing such disqualifications or of any other misbehavior by which the rights of any party have been materially prejudiced; or (5) the arbitrators exceeded their powers, or so imperfectly executed them, that a mutual, final and definite award upon the subject matter submitted to them was not made. x x x[27] (Citation omitted)
