Arbitration Agreements Need Not Be Signed: CIAC Jurisdiction in Construction Disputes

---

The Supreme Court has clarified a crucial point for construction industry stakeholders: an agreement to submit a construction dispute to the Construction Industry Arbitration Commission (CIAC) does not need to be signed by the parties. In Federal Builders, Inc. v. Power Factors, Inc. (G.R. No. 211504, March 8, 2017), the Court held that a written arbitration clause—even one contained in an unsigned draft contract—can be enough to vest the CIAC with jurisdiction.

The ruling is significant because construction projects often proceed based on drafts, change orders, and informal written communications. This decision provides guidance on when those documents may be sufficient to trigger CIAC arbitration.

The Case: An Unsigned Subcontractor Agreement

Federal Builders, Inc. (Federal) was the general contractor for the Bullion Mall project. In 2004, Federal engaged Power Factors, Inc. (Power) as its subcontractor for electrical works worth P18 million. The parties negotiated a Contract of Service that included an arbitration clause naming the CIAC as the forum for disputes.

Power performed the work but claimed unpaid amounts totaling over P11 million. When demands went unheeded, Power filed a request for arbitration with the CIAC in October 2009, invoking the arbitration clause in the Contract of Service.

Federal moved to dismiss, arguing that the CIAC had no jurisdiction because the Contract of Service was merely a draft that was never signed by both parties. Federal's counsel had earlier manifested agreement to arbitration, but Federal later claimed this did not bind it.

The Issue: Does an Unsigned Arbitration Clause Confer Jurisdiction?

The central question was whether the CIAC could take jurisdiction over the dispute when the arbitration agreement appeared only in an unsigned draft contract.

The Ruling: Written Intent Is Enough

The Supreme Court ruled against Federal, affirming the CIAC's jurisdiction. The Court emphasized that the CIAC's jurisdiction is over the dispute, not over the contract itself. The signing or non-signing of the contract does not determine whether the CIAC can hear the case.

The Court relied on Rule 4, Section 4.1.2 of the CIAC Revised Rules of Procedure, which expressly provides that an arbitration agreement must be in writing but need not be signed by the parties, as long as the intent to submit disputes to arbitration is clear. The agreement may take the form of an exchange of letters, telefaxes, telexes, telegrams, electronic mail, or any other mode of written communication.

This liberal approach contrasts with the general Arbitration Law (Republic Act No. 876), which requires arbitration agreements to be subscribed by the party sought to be charged. The Court noted that this signature requirement is conspicuously absent from the CIAC Revised Rules, reflecting the policy of encouraging alternative dispute resolution.

The Contract Was Valid Despite Being Unsigned

The Court also found that a valid contract existed between Federal and Power even without a signed document. Under Articles 1318, 1356, and 1357 of the Civil Code, contracts are obligatory in whatever form they are entered into, provided the essential requisites—consent, object, and cause—are present.

Here, Power had already executed the works, Federal had made payments, and the parties had no issue with the contract's provisions other than the downpayment amount. The arbitration clause itself was unchallenged until the dispute arose. The Court noted that Federal could not rely on the draft contract when it was beneficial to its defense while rejecting its existence to avoid CIAC jurisdiction.

Practical Takeaways

• Unsigned documents can trigger CIAC jurisdiction. A written arbitration clause in a draft contract, exchange of emails, or other written communication may be sufficient if the intent to arbitrate is clear.
• CIAC rules differ from the general Arbitration Law. Unlike R.A. 876, the CIAC Revised Rules do not require the parties' signatures on the arbitration agreement.
• Parties should review all written communications. Even informal documents exchanged during negotiations may later be used to establish an agreement to arbitrate.
• Performing work under a draft contract creates obligations. A party cannot accept the benefits of an unsigned contract while denying its existence to avoid arbitration.
• Any doubt is resolved in favor of arbitration. Philippine courts favor alternative dispute resolution in construction cases, consistent with the policy behind Executive Order No. 1008.
