DECISION LEONEN, J.: Generally, judicial review of arbitral awards is permitted only on very narrow grounds. Republic Act No. 876, or the Arbitration Law, does not allow an arbitral award to be revisited without a showing of specified conditions,' which must be proven affirmatively by the party seeking its review. The Special Rules of Court on Alternative Dispute Resolution, implementing the Alternative Dispute Resolution Act of 2004, mandate that arbitral awards will not be vacated "merely on the ground that the arbitral tribunal committed errors of fact, or of law, or of fact and law, as the court cannot substitute its judgment for that of the arbitral tribunal." Parties are even "precluded from filing an appeal or a petition for certioran questioning the merits of an arbitral award."s On the other hand, arbitral awards by the Construction Industry Arbitration Commission may only be appealed on pure questions of law, though not all will justify an appeal. Consistent with the strict standards for judicial review of arbitral awards, only those appeals which involve egregious errors of law may be entertained. Given its technical expertise, the Construction Industry Arbitration Commission is given a wide latitude of discretion so that it may resolve all issues before it in a fair and expeditious manner. Included within the bounds of its discretion are situations where it resolves, on the basis of equity, to order a party to compensate a contractor for any unpaid work done. For this Court's resolution is a Petition for Review on Certiorari assailing the March 21, 2012 Decision and June 25, 2012 Resolution of the Court of Appeals, which upheld the April 11, 2002 Arbitral Award" of the Construction Industry Arbitration Commission. The arbitral tribunal had ordered Metro Bottled Water Corporation (Metro Bottled Water) to pay Andrada Construction & Development Corporation, Inc. (Andrada Construction) the amount of P4,607,523.40 with legal interest from November 24, 2000 as unpaid work accomplishment in the construction of its manufacturing plant. On April 28, 1995, Metro Bottled Water and Andrada Construction entered into a Construction Agreement" for the construction of a reinforced concrete manufacturing plant in Gateway Business Park, General Trias, Cavite for the contract price of P45,570,237.90. The Construction Agreement covered all materials, labor, equipment, and tools, including any other works required."It provided
