G.R. No. 160215 - Hydro Resources Contractors Corp. vs. National Irrigation Administration

Case Summary (G.R. No. 160215)

Parties and Setting; Principal Legal Provisions

Hydro filed a request for arbitration with CIAC for CIAC Case No. 18-94, seeking payment of a foreign exchange differential that NIA refused to honor. NIA responded with laches, estoppel, and lack of jurisdiction as special defenses and later contested CIAC’s jurisdiction through multiple appellate remedies. The controversy also raised issues on prescription, the proper rate of exchange to apply, the effect (if any) of R.A. No. 529 on the contract’s foreign currency provisions, the alleged procedural defect in NIA’s Certification of Non-Forum-Shopping, and whether NIA’s conduct amounted to forum-shopping.

The decision discussed and applied, among others, Sec. 25 of the Contract’s General Conditions (GC-25) governing interim dispute settlement and a thirty-day period for invoking arbitration; Article 1155 of the Civil Code on the interruption of prescription by written extrajudicial demand and written acknowledgment; Article 1112 on the renunciation of prescription; Article 1431 of the Civil Code on estoppel based on a party’s intentional leading of another; and the statutory framework of R.A. No. 529 as discussed in relation to R.A. No. 4100’s amendments.

Factual Background: The MPI-C-2 Contract and the Foreign Currency Allocation

In a competitive bidding conducted in August 1978, NIA awarded Contract MPI-C-2 to Hydro for the main civil works of the Magat River Multi-Purpose Project. The contract price was P1,489,146,473.72, consisting of a peso component of P1,041,884,766.99 and a US dollar component of $60,657,992.37, valued at an exchange rate of P7.3735 to the dollar, equivalent to P447,361,706.73.

On November 6, 1978, the parties signed Amendment No. 1, by which NIA agreed to increase the foreign currency allocation for equipment financing from US$28,000,000.00 for the first and second years of the contract to US$38,000,000.00, with full availability during the first year to enable Hydro to purchase required equipment and spare parts, subject to NIA’s approval. On April 9, 1980, the parties executed a Memorandum of Agreement (MOA) agreeing that Hydro could directly avail itself of the foreign currency component solely to purchase necessary spare parts and equipment for the project, primarily to avoid procurement delays. Subsequently, a Supplemental Memorandum of Agreement expanded the items financed from the foreign currency component to include construction materials, supplies and services, as well as equipment and materials for incorporation into the permanent works.

Hydro substantially completed the project in 1982, and NIA made final acceptance on February 14, 1984. During performance, the peso’s foreign exchange value against the US dollar declined. When Hydro’s availments of the foreign currency component exceeded the foreign currency payable to it for a particular period, NIA charged interest in dollars computed using the prevailing exchange rate rather than the fixed rate of P7.3735 to the dollar. However, when Hydro received payments from NIA in Philippine pesos, NIA deducted amounts from Hydro’s foreign currency component using the fixed exchange rate of P7.3735 instead of the prevailing exchange rate.

After project completion, a final reconciliation showed that Hydro’s total entitlement to the foreign currency component exceeded the amount of US dollars required to repay NIA’s advances made for Hydro’s account in importing new equipment, spare parts, and tools. Hydro then requested final payment for the underpayment resulting from foreign exchange differentials allegedly caused by price escalations and extra work orders.

The Joint Computation and NIA’s Refusal

In 1983, Hydro and NIA prepared a joint computation denominated “MPI-C-2 Dollar Rate Differential on Foreign Component of Escalation.” Based on that joint computation, Hydro remained entitled to a foreign exchange differential of US$1,353,771.79, equivalent to P10,898,391.17. Hydro presented its claim to NIA on August 12, 1983, but NIA refused to honor it. Hydro made repeated demands until NIA Administrator Federico N. Alday, Jr. rejected the claim with finality on January 6, 1987.

After the final rejection, Hydro filed an arbitration request with CIAC on December 7, 1994, nominating six (6) arbitrators. The case was docketed as CIAC Case No. 18-94. NIA filed an Answer with Compulsory Counterclaim invoking laches, estoppel, and lack of jurisdiction. The parties later agreed on the Terms of Reference and the issues submitted to arbitration. On March 13, 1995, NIA filed a Motion to Dismiss questioning CIAC’s jurisdiction, but CIAC deferred resolution and set the case for hearing. NIA’s reconsideration motion was denied by CIAC in an order dated April 25, 1995.

NIA then sought relief from the Court of Appeals through certiorari and prohibition in CA-G.R. SP No. 37180, which the Court of Appeals dismissed on June 28, 1996. NIA challenged that dismissal in the Supreme Court via a special civil action for certiorari, docketed as G.R. No. 129169. Meanwhile, CIAC promulgated its decision on June 10, 1997, ruling in Hydro’s favor.

Appellate and Arbitration Timelines: CA-G.R. SP No. 44527 and Finality

NIA filed a Petition for Review on Appeal before the Court of Appeals, docketed as CA-G.R. SP No. 44527, challenging the CIAC decision. During the pendency of CA-G.R. SP No. 44527, the Supreme Court dismissed the earlier certiorari petition in G.R. No. 129169, holding that CIAC had jurisdiction and directing the Court of Appeals to proceed with reasonable dispatch. NIA did not move for reconsideration; therefore, that ruling became final and executory on December 15, 1999.

Subsequently, the Court of Appeals rendered the assailed decision in CA-G.R. SP No. 44527, reversing CIAC on multiple grounds: (one) Hydros claim had prescribed; (two) assuming entitlement, the exchange rate should be based on a fixed rate; (three) Hydros claim was contrary to R.A. No. 529; (four) NIA’s Certification of Non-Forum-Shopping was proper despite being signed by counsel rather than an authorized representative; and (five) NIA did not engage in forum-shopping. The Court of Appeals denied Hydro’s motion for reconsideration in a resolution dated September 24, 2003. Hydro then filed the present petition for review on certiorari under Rule 45.

Parties’ Contentions on Prescription and the Thirty-Day Arbitration Clause

The first major issue concerned whether Hydro’s claim had prescribed. The Court of Appeals applied Sec. 25 of the General Conditions of the contract (GC-25), which required unresolved disputes to be submitted to the NIA Administrator for decision within thirty (30) calendar days from receipt of written notice and allowed arbitration only if the Contractor delivered, within thirty (30) calendar days from receipt of the Administrator’s decision, a written notice expressing intent to arbitrate.

Applying that clause, the Court of Appeals reasoned that NIA’s Administrator denied Hydro’s claim on January 7, 1986, and that Hydro therefore should have timely invoked arbitration within the contractual period. It found that Hydro instead continued sending letters reiterating rejected reasons. It ruled that CIAC erred in granting Hydro’s claim and treated Hydro’s right as clearly prescribed.

Hydro disputed that conclusion. The Supreme Court held that the Court of Appeals overlooked that NIA Administrator Federico N. Alday, Jr. denied Hydro’s claim with finality only on January 6, 1987, and that Hydro received the letter denying the claim on January 27, 1987. The Supreme Court treated that final denial as the trigger of the thirty-day period under GC-25, and it emphasized that Hydro’s subsequent arbitration-invocation letter dated February 18, 1987, received by NIA on February 19, 1987, was within the thirty-day period, and thus timely.

The Supreme Court further clarified the contractual design behind GC-25. It accepted that the thirty-day limitation was intended to apply to disputes arising during actual construction, where the purpose of interim settlement was to avoid delays in project completion. It agreed with CIAC’s reasoning that the dispute at issue had arisen after completion of the project; hence, the rationale for strictly applying the thirty-day limitation no longer applied. It therefore rejected the Court of Appeals’ restrictive construction of the clause.

Written Acknowledgment Under Article 1155: The Joint Computation

The decision also addressed whether Hydro’s claim was interrupted by a written acknowledgment of the debt. The Supreme Court sustained CIAC’s view that the Joint Computation prepared by Hydro and NIA in April 1983 constituted a written acknowledgment of the debt by the debtor under Article 1155 of the Civil Code, which provides that prescription is interrupted by written acknowledgment of the debt by the debtor.

The Court of Appeals had rejected CIAC’s finding by declaring that the Administrator’s act of signing the joint computation was ultra vires. The Supreme Court rejected that approach. It reasoned that the Administrator was the highest officer of NIA and that NIA’s Administrator was empowered by the contract to grant or deny foreign currency differential claims, which necessarily required verification of computations. It also noted that NIA itself never disputed the Administrator’s capacity to sign the joint computation and knew the Administrator had such capacity.

Even assuming arguendo lack of authority, the Supreme Court held NIA was estopped after repeatedly representing to Hydro that the Administrator possessed such authority. It explained that corporations may be held in estoppel from denying, against third persons, the authority of officers or agents who appear to have authority through ostensible authority. Thus, the signing of the joint computation could not be disavowed to Hydro’s prejudice.

Waiver of Prescription and Conduct Before CIAC

Case Syllabus (G.R. No. 160215)

Parties and Procedural Posture

Hydro Resources Contractors Corporation (Hydro) commenced CIAC arbitration against National Irrigation Administration (NIA) for payment of a foreign exchange differential arising from Contract MPI-C-2.
The dispute reached the Construction Industry Arbitration Commission (CIAC) as CIAC Case No. 18-94.
CIAC promulgated a decision on June 10, 1997 in favor of Hydro.
The Court of Appeals reversed CIAC by its Decision dated October 29, 2002 and Resolution dated September 24, 2003 in CA-G.R. SP No. 44527.
Hydro filed a petition for review on certiorari under Rule 45 to set aside the Court of Appeals rulings and reinstate CIAC.

Key Contractual Background

NIA awarded Hydro Contract MPI-C-2 after a competitive bidding conducted in August 1978 for the main civil work of the Magat River Multi-Purpose Project.
The contract price totaled P1,489,146,473.72, consisting of a peso component of P1,041,884,766.99 and a US$ component valued at $60,657,992.37 at an exchange rate of P7.3735 to the dollar.
On November 6, 1978, the parties executed Amendment No. 1, under which NIA increased the foreign currency allocation for equipment financing from US$28,000,000.00 (for the first and second years) to US$38,000,000.00, to be made available in full during the first year to purchase needed equipment and spare parts approved by NIA.
On April 9, 1980, the parties executed a Memorandum of Agreement (MOA) allowing Hydro to directly avail of the foreign currency component solely to purchase necessary spare parts and equipment for the project, to avoid procurement delays.
Subsequently, the parties entered into a Supplemental Memorandum of Agreement to include construction materials, supplies and services, and equipment and materials for incorporation in the permanent works as items to be financed out of the foreign currency portion.
Hydro substantially completed the project in 1982, and NIA made final acceptance on February 14, 1984.

Foreign Exchange Computation Dispute

During performance, the foreign exchange value of the peso against the US dollar declined and deteriorated.
When Hydro’s availment of the foreign currency exceeded foreign currency payable for a particular period, NIA charged interest in dollars using the prevailing exchange rate, not the fixed rate of P7.3735.
When Hydro received payments from NIA in Philippine pesos, NIA deducted from Hydro’s foreign currency component using the fixed exchange rate of P7.3735 rather than the prevailing exchange rate.
After completion, the parties conducted a final reconciliation of Hydro’s total entitlement to the foreign currency component, showing entitlement exceeding the amount of US dollars required to repay NIA advances for imported new equipment, spare parts, and tools.
Hydro requested full and final payment for the underpayment of the foreign exchange portion caused by price escalations and extra work orders.
In 1983, Hydro and NIA prepared a joint computation denominated “MPI-C-2 Dollar Rate Differential on Foreign Component of Escalation.”
Based on that joint computation, Hydro was still entitled to a foreign exchange differential of US$1,353,771.79, equivalent to P10,898,391.17.
Hydro presented its claim to NIA on August 12, 1983, but NIA refused to honor it and repeatedly rejected Hydro’s demands until the NIA Administrator, Federico N. Alday, Jr., issued a final denial on January 6, 1987.

Arbitration Proceedings and Jurisdiction Challenges

On December 7, 1994, Hydro filed a request for arbitration with CIAC and nominated six (6) arbitrators, docketed as CIAC Case No. 18-94.
NIA filed an Answer with compulsory counterclaim and special defenses including laches, estoppel, and alleged lack of jurisdiction by CIAC.
After arbitrators were appointed, the parties agreed on Terms of Reference and the issues submitted for arbitration.
On March 13, 1995, NIA filed a Motion to Dismiss questioning CIAC jurisdiction, but CIAC deferred resolution and set the case for hearing to receive evidence.
NIA sought reconsideration, but CIAC denied it in an Order dated April 25, 1995.
NIA filed certiorari and prohibition with the Court of Appeals, docketed as CA-G.R. SP No. 37180, which dismissed the petition in a Resolution dated June 28, 1996.
NIA challenged that dismissal before the Supreme Court in G.R. No. 129169, but the Supreme Court dismissed the special civil action on the ground that CIAC had jurisdiction, directing the Court of Appeals to proceed with reasonable dispatch.
NIA did not move for reconsideration, and the Supreme Court ruling became final and executory on December 15, 1999.
While CA-G.R. SP No. 44527 was pending, CIAC issued its decision favoring Hydro on June 10, 1997.

Court of Appeals Grounds for Reversal

The Court of Appeals reversed CIAC on multiple grounds, namely:
The Court of Appeals held that Hydro’s claim had prescribed.
The Court of Appeals ruled that even if Hydro was entitled to the claim, the exchange rate should be based on a fixed rate.
The Court of Appeals held that Hydro’s claim was contrary to R.A. No. 529.
The Court of Appeals ruled that NIA’s Certification of Non-Forum-Shopping was proper even if signed by counsel and not by an authorized NIA representative.
The Court of Appeals ruled that NIA did not engage in forum-shopping.
The Court of Appeals denied Hydro’s motion for reconsideration in a Resolution dated September 24, 2003.

Issues Raised for Supreme Court Review

The petition required the Court to determine whether Hydro’s claim had prescribed under Section 25 of the General Conditions of the contract.
The Court also addressed whether CIAC correctly treated the joint computation signed by NIA’s Administrator as a written acknowledgment interrupting prescription under Article 1155, Civil Code.
Another issue required the Court to assess whether NIA’s conduct waived or was estopped from invoking the prescriptive period.
The Court had to resolve whether R.A. No. 529 applied to the international tendered contract funded by the IBRD, and whether any prohibition affected the enforceability of Hydro’s claim.
The Court also addressed whether the foreign exchange differential should be computed using the prevailing escalating exchange rates rather than the fixed rate.
The Court further determined whether NIA committed forum-shopping and whether a certification of non-forum-shopping signed only by counsel was valid.

Prescription Under Contract GC-25

The Court of Appeals found prescription based on Section 25 of the General Conditions, which required arbitration initiation within thirty (30) calendar days from receipt of the NIA Administrator’s decision.
The Supreme Court held the Court of Appeals erred by overlooking NIA’s final denial on January 6, 1987, issued by Administrator Federico N. Alday, Jr., which reiterated NIA’s refusal to reverse its earlier decision.
The Supreme Court found that Hydro received the January 6, 1987 letter on January 27, 1987.
The Supreme Court held that Hydro then acted within the contractual thirty-day period by sending a letter on February 18, 1987 manifesting desire to submit the dispute to arbitration, which NIA received on February 19, 1987.
The Supreme Court also reasoned that the thirt
