Proving Negligence in Quasi-Delict Cases: The Supreme Court's Latest Word

The Supreme Court recently denied a petition in Laza v. Standard Insurance Co., Inc. (G.R. No. 279772, June 29, 2026), affirming the Court of Appeals' ruling that a driver who overtook on the shoulder of a highway was negligent and liable for damages under the law on quasi-delicts. The case clarifies how courts evaluate negligence in vehicular accidents and reinforces the limits of a petition for review on certiorari.

The Facts of the Case

On November 6, 2014, a Honda CR-V driven by Peter Paul Nang collided with a Toyota Innova driven by Danilo Agpoon along the National Highway in Bauang, La Union. Nang was turning left into a property across the road when the Innova, overtaking a Nissan Sentra on the right shoulder, hit the CR-V's front portion.

Standard Insurance Co., Inc., as Nang's insurer, paid PHP 270,509.42 for the CR-V's repairs. As subrogee, it sued Agpoon and Mark Laza, the Innova's registered owner, for recovery of sum of money based on quasi-delict.

The Metropolitan Trial Court dismissed the complaint, finding Standard Insurance failed to prove Agpoon's negligence. The Regional Trial Court reversed, holding that Agpoon's presence on the road shoulder violated Section 52 of Republic Act No. 4136 (the Land Transportation and Traffic Code), creating a presumption of negligence under Article 2185 of the Civil Code. The Court of Appeals affirmed.

The Issue Presented

The sole issue was whether the Court of Appeals erred in sustaining the RTC's decision in favor of Standard Insurance. The petitioners argued that Nang was negligent for making a sudden U-turn and violating right-of-way rules under Sections 42(a) and 44(a) of Republic Act No. 4136.

The Supreme Court's Ruling

The Supreme Court denied the petition, holding that the issues raised were factual in nature. Under Rule 45, Section 1 of the Rules of Court, a petition for review on certiorari must raise only questions of law. The Court is not a trier of facts, and the petitioners failed to show any exception to this rule, including grave abuse of discretion on the part of the appellate court.

The Court reiterated the elements of a quasi-delict claim under Article 2176 of the Civil Code: (1) damage suffered by the plaintiff; (2) fault or negligence of the defendant; and (3) a causal connection between the fault or negligence and the damage, known as proximate cause.

Applying these elements, the Court found that Standard Insurance proved its claim: the CR-V sustained damages, Agpoon admitted he was overtaking when the collision occurred, and his negligence was the proximate cause of the damage. The Court also approved the CA's finding that Nang had not violated right-of-way rules, as a Sentra had yielded to him and he had already occupied a substantial portion of the opposite lane when the Innova struck him.

The Court sustained the award of PHP 270,509.42 in actual damages, PHP 30,000.00 in attorney's fees, and 6% interest per annum, holding Laza vicariously liable as Agpoon's employer under Article 2180 of the Civil Code.

Practical Takeaways

• Quasi-delict claims require proof of three elements: damage, negligence, and proximate cause. A plaintiff must substantiate each element with evidence; mere allegations are not enough.
• Violating a traffic regulation creates a presumption of negligence under Article 2185 of the Civil Code. A driver who overtakes on the shoulder, as Agpoon did, bears the burden of rebutting this presumption.
• Rule 45 petitions are limited to questions of law. The Supreme Court will not re-examine factual findings of lower courts unless a clear exception applies, such as grave abuse of discretion.
• Vehicle owners can be vicariously liable for the negligence of their drivers under Article 2180, making them jointly and severally liable for damages.
• Insurers can recover as subrogees: after paying a claim, an insurer steps into the insured's shoes and may sue the negligent party for reimbursement.
