Evident Partiality in Philippine Arbitration: When Courts Can Vacate an Award

Evident Partiality in Philippine Arbitration: When Courts Can Vacate an Award

Arbitration is meant to be a final and binding way to resolve disputes outside court. But what happens when a party believes the arbitrator was biased? The Supreme Court recently clarified the standard for proving "evident partiality" — a recognized ground for vacating an arbitral award — in Tri-Mark Foods, Inc. v. Gintong Pansit, Atbp., Inc. (G.R. No. 215644, September 14, 2021).

The case is significant because it draws a clear line between an arbitrator's alleged bias and mere disagreement with how the arbitrator weighed the evidence. Only the former can justify setting aside an award.

The Dispute: A Franchise Agreement Gone Sour

Tri-Mark Foods, Inc. granted Gintong Pansit, Atbp., Inc. a franchise to operate a Ling Nam Noodle House branch. When a payment dispute arose, Tri-Mark initiated arbitration with the Philippine Dispute Resolution Center, Inc. (PDRCI). The sole arbitrator ruled largely in Tri-Mark's favor, ordering Gintong Pansit and its officers to pay over ₱5.5 million.

Gintong Pansit then filed a petition to vacate the award before the Regional Trial Court (RTC), arguing that the arbitrator showed evident partiality by disregarding their evidence of overpricing and breach of the franchise agreement. The RTC vacated the award, and the Court of Appeals (CA) affirmed. Tri-Mark elevated the case to the Supreme Court.

The Issue: What Constitutes Evident Partiality?

The central question was whether courts may vacate an arbitral award on the ground of evident partiality simply because they disagree with how the arbitrator weighed and appreciated the evidence presented.

The Ruling: Bias Must Be Demonstrated, Not Inferred from an Unfavorable Result

The Supreme Court granted Tri-Mark's petition, ruling that the lower courts erred in vacating the award. The Court emphasized that the grounds for vacating a domestic arbitral award under the Special ADR Rules are exclusive. These grounds — including evident partiality — do not concern the correctness of the award; they relate to the misconduct of the arbitrator.

Adopting the "reasonable impression of partiality" standard from the earlier case of RCBC Capital Corp. v. Banco de Oro Unibank, Inc., the Court held that a party seeking to vacate an award must show that a reasonable person would have to conclude that the arbitrator was partial to one party. The alleged bias must be direct, definite, and capable of demonstration — not remote, uncertain, or speculative.

The Court stressed that arbitrators are not held to the same standard of conduct imposed on judges. An arbitrator's interpretation of a contract or assessment of evidence that happens to disfavor one party does not, by itself, prove evident partiality. Courts cannot substitute their judgment for that of the arbitral tribunal on factual or legal errors.

Key Principles from the Decision

• The grounds for vacating an arbitral award under Rule 11.4 of the Special ADR Rules and Section 24 of Republic Act No. 876 are exclusive; courts must disregard any other ground.
• Evident partiality requires a showing that a reasonable person would have to conclude the arbitrator was biased — not merely that the award was unfavorable.
• Courts may not vacate an award merely because the arbitrator committed errors of fact or law; judicial review is limited to the validity of the arbitration agreement and the regularity of the proceedings.
• An arbitrator's failure to accept a party's evidence or to rule in that party's favor is not evidence of bias.

Practical Takeaways

• Merits appeals are not allowed. A party unhappy with the outcome of arbitration cannot relitigate the case before the courts. The grounds for vacating an award are narrow and exclusive.
• Proving evident partiality is difficult. A party must point to concrete conduct showing bias — not just argue that the arbitrator ignored evidence or made a wrong decision.
• Choose arbitrators carefully. Since arbitrators are not held to the strict standards of judicial conduct, parties should vet prospective arbitrators for potential conflicts or bias before appointment.
• Preserve the record. To challenge an award for evident partiality, the moving party must be able to demonstrate from the record that the arbitrator's conduct was so biased as to destroy fundamental fairness.
• Arbitration remains final. The decision reinforces the pro-arbitration policy of Philippine law, ensuring that awards are respected unless a truly valid ground for vacation exists.
