Case Summary (G.R. No. 172778)

Summary of Facts

On July 6, 1995 at about 11:30 a.m., a passenger bus driven by petitioner collided with a tricycle that was overtaking a pickup on a two‑lane national highway with two blind curves. The collision caused the deaths of four tricycle passengers and injuries to five others. The tricycle was reportedly overloaded with eight passengers. The tricycle had been overtaking a Mitsubishi pickup when it suddenly occupied the bus’s lane and was struck. Police measurements at the scene included a point of impact one foot across the centerline and a sixty‑foot skid mark attributed to the bus.

Procedural History

Petitioner was charged in the Municipal Trial Court (MTC) with reckless imprudence resulting in multiple homicide and reckless imprudence resulting in serious physical injuries, and with damage to property. The MTC convicted him of reckless imprudence resulting in multiple homicide. The Regional Trial Court (RTC) affirmed the conviction with modifications to the penalty and the civil awards. The Court of Appeals (CA) affirmed the RTC decision in toto. Petitioner filed a petition for review under Rule 45 to the Supreme Court.

Evidence at Trial

Prosecution witnesses included an eyewitness (Cagakit) who placed a fast moving vehicle as the cause of the collision, investigating police officers who prepared a sketch and measured skid marks, and several injured passengers and family members giving factual accounts and claims for damages. The defense (petitioner) testified to 26 years’ professional driving experience, familiarity with the road’s blind curves, that he slowed for the first curve, accelerated when his lane appeared clear on the second curve, and that the tricycle suddenly occupied his lane while overtaking.

MTC Rationale and Judgment

The MTC found petitioner guilty of reckless imprudence resulting in multiple homicide, reasoning that the sixty‑foot skid mark evidenced negligent operation and excessive speed given the blind curves and road conditions. The MTC concluded that, had the bus driver exercised reasonable care and reduced speed commensurate with road conditions, the accident may have been avoided or damage would have been minor.

RTC Decision and Modifications

The RTC affirmed the conviction but modified the penalty and the quantum of civil liabilities. It imposed an indeterminate sentence for the complex crime and adjusted indemnities, funeral expenses, moral and exemplary damages, attorney’s fees, and awarded compensatory damages to the tricycle owner for the damaged vehicle.

CA Ruling

The Court of Appeals affirmed the RTC, concluding that both the bus driver and the tricycle driver were negligent—the tricycle driver for illegally overtaking approaching a blind curve, and the bus driver for failing to exercise adequate precaution when approaching a known blind curve. The CA emphasized that driving on the correct side of the road does not relieve a driver from the duty to prevent collisions.

Issues Raised Before the Supreme Court

Petitioner argued (1) that his guilt was not proven beyond reasonable doubt and the mishap was a pure accident; (2) that the proximate cause was the tricycle driver’s unlawful overtaking and overloading of the tricycle; (3) that the tricycle was operating in violation of its franchise and RA 4136; and (4) that his conviction violated due process and the presumption of innocence.

Governing Legal Standards

Reckless imprudence under Article 365 of the Revised Penal Code requires a voluntary act or omission without malice that results in material damage due to inexcusable lack of precaution, considering the actor’s occupation, intelligence, physical condition and circumstances. Criminal liability for driving requires a direct causal connection between negligent operation and the resulting injuries or deaths; reckless imprudence in vehicular cases requires more than mere negligence—a willful or wanton disregard of consequences. Proximate cause entails the first cause in a natural and continuous sequence producing the injury, unbroken by an efficient intervening cause.

Supreme Court’s Review Framework

The Court acknowledged the general binding effect of trial court fact‑findings, especially when affirmed by the CA, but noted well‑recognized exceptions permitting review: manifestly mistaken inferences, grave abuse of discretion, findings based on speculation or contradicted by record evidence, material overlooking of undisputed facts, and similar grounds. The Court found several exceptions applicable in this case.

Supreme Court’s Analysis of Causation and Negligence

After reviewing the record, the Supreme Court concluded that the proximate cause of the collision was the tricycle driver’s reckless overtaking while approaching a blind curve in violation of RA 4136, Section 41. The bus was cruising on its rightful lane when the tricycle suddenly swerved into that lane; the collision would not have occurred had the tricycle driver remained in his lane. Thus, the initial and efficient cause of the harm was the tricycle driver’s conduct.

Evaluation of Evidence Relating to Bus Speed

The Court rejected the lower courts’ reliance on the sixty‑foot skid mark and the eyewitness’s characterization of a “fast moving vehicle” as proof that petitioner was driving with criminal recklessness. The testimony that the bus was “fast” lacked quantification and was not probative that the bus exceeded allowable speed limits under RA 4136, Section 35. The Court found insufficient evidence to sustain a determination that petitioner’s speed amounted to reckless imprudence.

Application of Precedent

The Court cited Vallacar Transit, Inc. v. Catubig and similar authority where the immediate and proximate cause was held to be the other driver who overtook while approaching a curve. Consistent with those precedents, when the other vehicle’s imprudence is the proximate cause, the driver of the larger vehicle should be acquitted of criminal responsibility, though civil liability may remain under quasi‑delic
