G.R. No. L-16086, May 29, 1964
M. RUIZ HIGHWAY TRANSIT, INC. and MARTIN BUENA, petitioners, vs. COURT OF APPEALS, GUILLERMO MONSERRAT and MARTA CONSIGNADO, respondents.

FACTS

The spouses Guillermo Monserrat and Marta Consignado, along with their four-year-old daughter Victoria, were paying passengers on a bus owned by M. Ruiz Highway Transit, Inc. and driven by Martin Buena. While the bus was in motion in Sta. Rosa, Laguna, a rear tire exploded. The blast created a hole in the floor of the bus precisely where Victoria was standing, causing her to fall through. She sustained fatal injuries and died that same morning. The parents sued for damages.
The trial court dismissed the complaint, ruling the explosion was an act of God and that the parents had waived their claims through documents (Exhibits 2 and 3) executed on the day of the accident. In these documents, the distressed and illiterate parents stated the incident was nobody’s fault and an act of God, and they acknowledged receiving P150.00 as voluntary help from the carrier. The Court of Appeals reversed, finding the carrier negligent and the documents ineffective as a waiver, awarding indemnity, moral damages, and attorney’s fees.

ISSUE

The core issues were whether the carrier exercised the required extraordinary diligence, whether the tire explosion constituted a caso fortuito, and whether the documents signed by the parents constituted a valid waiver of their right to claim damages.

RULING

The Supreme Court affirmed the Court of Appeals’ decision, holding the carrier liable. The legal logic is anchored on the presumption of negligence under Article 1756 of the Civil Code, which applies to common carriers. As paying passengers, a contract of carriage existed, imposing on the carrier the obligation to observe extraordinary diligence. The fatal accident—where the bus floor gave way—itself reinforced the presumption of the carrier’s failure to provide a safe vehicle.
The Court found the carrier failed to rebut this presumption. The appellate court’s factual findings, which are binding, established negligence: the bus was overcrowded, overspeeding, and had a weak floor. The cause of the tire blow-out was attributed to the carrier’s lack of due care in maintenance, load, or speed, not a true caso fortuito. Even if the blow-out was accidental, the carrier remained liable for the separate negligence of failing to maintain a safe floor that would not give way.
Regarding the documents (Exhibits 2 and 3), the Court ruled they did not constitute a valid waiver or release. They merely expressed the parents’ mistaken belief, formed while they were confused, indigent, and grieving, that the carrier was not liable. The P150.00 was a voluntary helper’s gift, not compensation. The award of P6,000 as death indemnity was sustained as within judicial discretion, and moral damages were properly awarded to the parents under the Civil Code. Attorney’s fees were also justified given the parents’ indigent status.
