Taisei Shimizu Joint Venture vs. Commission on Audit

Factual Background

Taisei Shimizu Joint Venture contracted with the Department of Transportation on March 15, 2004 for the construction of the New Iloilo Airport. After project completion, TSJV alleged unpaid billings and filed with the Construction Industry Arbitration Commission (CIAC) a Request for Arbitration and Complaint seeking multiple monetary claims arising from variation orders, currency conversion losses, interest on delayed payments, price adjustments, extension-of-time related costs, additional embankment works, damages for delayed payment of aggregates, and litigation costs; the aggregate original claim exceeded Php2,316,687,603.03.

Arbitral Proceedings and Award

The CIAC conducted arbitration and, by its Final Award dated December 11, 2014, granted several claims in favor of TSJV totaling Php223,401,870.83 and directed the DOTr to pay six percent per annum interest from the finality of the award until full payment. On DOTr’s motion for correction, the CIAC issued an Order dated February 20, 2015 reducing one component of the award and amending the total to Php216,073,986.89.

Attempts at Execution and COA Petition

TSJV sought execution of the CIAC award. The CIAC, by resolution dated April 22, 2015, directed implementation of a writ of execution. The DOTr opposed garnishment on grounds that the funds were public and later informed TSJV that COA approval was a condition precedent to payment. Several banks reported no funds in DOTr’s name; the Land Bank advised that COA approval was required. TSJV then filed a petition with the Commission on Audit for enforcement and payment of the arbitral award. The DOTr, through the Office of the Solicitor General, acknowledged the CIAC award and its amended amount and stated it had no further comments on the arbitral determination.

COA Proceedings and Rulings

By Decision No. 2016-395 dated December 21, 2016, the Commission on Audit approved payment only to the extent of Php104,661,421.35 corresponding to Claim No. 4 and partially disapproved payment of the remaining awarded amounts. The COA grounded its disallowances on statutory and regulatory provisions, principally asserting that Claim No. 1 involved price adjustments subject to Section 61 of Republic Act No. 9184 and its IRR and that no prior approvals (including from NEDA and the head of the procuring agency) were shown; that interest and extension-of-time costs lacked statutory authorization; and that attorney’s fees were barred by Section 1, Rule 142 of the Rules of Court. TSJV moved for partial reconsideration, which the COA denied by Resolution No. 2018-047 dated January 22, 2018. COA Chairperson Michael G. Aguinaldo dissented, distinguishing between original money claims filed with COA and money claims arising from final and executory judgments.

Procedural History and Petition

TSJV filed a petition for certiorari under Rule 65 in relation to Rule 64 of the Rules of Court, alleging that the COA committed grave abuse of discretion by modifying and disallowing portions of a final and executory arbitral award. The COA defended its action as within its primary jurisdiction over money claims against the government and as an exercise of quasi-judicial audit authority to approve or disapprove payments even when based on a final judgment or award.

Issues Presented

The Supreme Court articulated the principal issues as: (i) whether the COA has exclusive jurisdiction over money claims due from or owing to the government; and (ii) whether, in the exercise of its audit power, the COA may disturb the final and executory decisions of courts, tribunals, or other adjudicative bodies.

Supreme Court's Ruling

The Court granted the petition. It held that while the Commission on Audit possessed primary jurisdiction over money claims against the government, that jurisdiction was not exclusive and did not empower COA to modify or set aside a final and executory award rendered by a tribunal that validly exercised jurisdiction. The Court ruled that the CIAC had exclusive jurisdiction over disputes arising from construction contracts voluntarily submitted to arbitration under Executive Order No. 1008, that the CIAC’s modified final award had become final and binding, and that the COA gravely abused its discretion by reweighing evidence and disallowing substantial portions of that award. The Court reversed and set aside COA Decision No. 2016-395 and Resolution No. 2018-047 insofar as they disapproved payment of Claim Nos. 1, 3, 5, and 8, and remanded the case to COA for expeditious payment of the balance of the arbitral award in the amount of Php111,412,565.54.

Legal Basis and Reasoning

The Court began from Article IX-D, Section 2(1), 1987 Constitution and statutory provisions such as P.D. No. 1445 and the COA Rules, recognizing COA’s broad audit mandate to examine, audit, and settle accounts and money claims. The Court nevertheless emphasized that nothing in the Constitution, statutes, or COA rules conferred original and exclusive jurisdiction over money claims to COA to the exclusion of courts or other tribunals. It relied on prior jurisprudence establishing that COA’s competence is circumscribed, that COA’s original jurisdiction is properly limited to liquidated claims and accounting matters, and that other specialized tribunals or courts may exercise concurrent or exclusive jurisdiction when statutes so provide. The Court construed E.O. No. 1008 as a specific law granting CIAC original and exclusive jurisdiction over construction disputes voluntarily submitted to arbitration; this specific grant prevailed over PD 1445’s general audit jurisdiction. The Court distinguished between two types of money claims confronting COA: (a) original claims filed with COA, typically liquidated and accounting in nature; and (b) claims that have been reduced to final and executory judgments or awards. For the latter, the Court reiterated the doctrines of res judicata and the immutability of final judgments, observing that COA lacked appellate power to reexamine factual and legal determinations made by a competent tribunal and could not override the finality of the CIAC award except under recognized exceptions (clerical errors, nunc pro tunc entries, void judgments, or other narrow circumstances). The Court held that COA’s proper role regarding final money judgments was aki
