Case Summary (G.R. No. 45629)

Key Dates

Accident: 12 August 1994. Complaint filed in RTC Antipolo: 14 November 1994. RTC judgment dismissing complaint: 7 February 2000. Court of Appeals decision reversing RTC: (date in prompt). Supreme Court decision reversing Court of Appeals and dismissing the case: 24 August 2011. Applicable constitutional framework: 1987 Philippine Constitution (decision 1990 or later).

Applicable Law

Civil Code provisions governing quasi-delict and presumptions: Article 2176 (liability for acts or omissions causing damage where there is fault or negligence) and Article 2185 (legal presumption of negligence when traffic regulations are violated). Standard of proof: preponderance of evidence for civil quasi-delict claims. Relevant jurisprudential principles on negligence per se and causal connection (as reflected in Sanitary Steam Laundry and AAnonuevo decisions) and on the limited probative value of affidavits of desistance.

Factual Narrative Presented by Parties

Respondents’ eyewitness (Gregorio Pomasin) testified that, while aboard the jitney, he saw the tractor-trailer descending a curve at excessive speed and encroaching into the jitney’s lane, causing the collision and resulting deaths/injuries. Petitioners’ driver, Jabon, testified that his tractor-trailer was ascending at about 35–40 km/h when he observed the opposite jitney falling off the road shoulder and running in a zigzag manner toward his lane; to avoid collision he swerved right, struck a tree and sacks of palay, and nonetheless was struck on the left fender by the jitney.

Casualties, Injuries and Immediate Responses

Multiple fatalities and injuries occurred among jitney passengers: some died instantly at the scene while others expired in hospital; several sustained injuries and were hospitalized. Jabon and a passenger in the truck were injured. Owner Tison gave immediate financial assistance (P1,000 each to respondents and P200,000 to Cynthia Pomasin), and Cynthia executed an Affidavit of Desistance.

Claims and Relief Sought by Respondents

Respondents sued petitioners for damages alleging negligence of petitioners’ driver. They sought indemnity for heirs of deceased passengers (P50,000 each), substantial amounts for hospitalization, medical and burial expenses, continuous medical expenses for Spouses Pomasin, moral damages, exemplary damages, loss of income for Cynthia, attorney’s fees, litigation expenses, and costs of suit.

Defendants’ Pleadings and Procedural Posture

Petitioners denied liability, contending the proximate cause was the negligence of the jitney driver, Laarni Pomasin. They asserted that Cynthia was authorized to settle (citing her Affidavit of Desistance). Petitioners moved to dismiss based on the affidavit; the motion was denied. The RTC ultimately dismissed the complaint in favor of petitioners; the Court of Appeals reversed and awarded damages to respondents; the Supreme Court granted petitioners’ petition and set aside the Court of Appeals decision.

Trial Court Findings and Reasoning

The RTC credited Jabon’s testimony as more reliable than the passenger Gregorio’s, reasoning that a driver has a superior opportunity for continuous observation and attention to the road, particularly in split-second highway incidents. The RTC found that the jitney fell off the shoulder, ran in a zigzag manner while descending a curve (thereby accelerating), and that the jitney driver’s lack of control was the proximate cause of the collision. The RTC also accepted Cynthia’s settlement evidence as indicating tacit consent by respondents, contributing to dismissal.

Court of Appeals Findings and Reasoning

The Court of Appeals credited Gregorio’s account, inferred that the gravity of damage to the jitney indicated excessive speed by the tractor-trailer, and relied on the fact that Jabon’s license bore restriction codes (2 and 3) to infer a violation of traffic regulation and thus presumption of negligence. The appellate court also held Tison liable for failure to prove due diligence in supervising the driver, and it disregarded Cynthia’s Affidavit of Desistance because she lacked written power of attorney and allegedly did not read the affidavit.

Issues on Appeal to the Supreme Court

Primary issue: which party’s negligence proximately caused the collision — the driver of the tractor-trailer or the driver of the jitney — i.e., a predominantly factual determination. Secondary issues: the effect, if any, of (a) the driver’s license restrictions and the presumption of negligence under Article 2185, and (b) the Affidavit of Desistance executed by Cynthia.

Supreme Court Standard of Review and Governing Principles

The Court reiterated that findings of fact by the Court of Appeals are normally conclusive, but exceptions permit review where appellate and trial findings are contradictory, grounded on speculation, manifestly mistaken, or where relevant facts were overlooked. The Court emphasized deference to trial courts’ credibility assessments, given their opportunity for first-hand observation, and reaffirmed the civil quasi-delict requisites under Article 2176: damage, fault/negligence, and causal connection. The standard of proof is preponderance of evidence.

Supreme Court’s Analysis on Credibility and Facts

The Supreme Court favored the RTC’s credibility assessment of Jabon over Gregorio’s conflicting testimony. It noted inconsistencies in Gregorio’s recounting (initially describing the road as “curving and downward,” later asserting the jitney was ascending), while Jabon’s testimony was consistent that the tractor-trailer was ascending and the jitney was descending, with the jitney having fallen into the shoulder and running zigzag. The Court found that the physical circumstances (a loaded jitney descending and thus tending to accelerate; the jitney’s fall into the shoulder) supported the RTC’s finding that the jitney lost control and was the proximate cause. The Court found no persuasive evidence that the tractor-trailer was speeding; Jabon’s uphill, loaded-vehicle context made high speed unlikely. The Court also observed that split-second decision-making in an uphill maneuver of a heavy tractor-trailer co
