G.R. No. 96132 - Magno vs. Court of Appeals

Petitioner: Delsan Transport Lines, Inc. (“Delsan”) – a domestic corporation owning and operating the vessel MT Larusan.
Respondent: American Home Assurance Corporation (“AHAC”) – a foreign insurance company licensed to do business in the Philippines, represented by its local agent, American-International Underwriters, Inc. (Phils.).

The vessel MT Larusan was engaged in transporting 1,986.627 kiloliters of Automotive Diesel Oil under a Contract of Afreightment from the Bataan Refinery Corporation to Caltex Phils., Inc.’s bulk depot in Bacolod City.
The shipment was insured by AHAC under two separate policies:

On August 5, 1984, Delsan received the diesel oil shipment on board the vessel, and delivery operations began upon arrival in Bacolod City on August 7, 1984.
During unloading (which commenced at approximately 1:30 PM), an incident occurred at about 10:30 PM when:

The vessel’s port bow mooring line was found to have been intentionally cut or stolen by unknown persons, causing the vessel to drift.
This drift led to the stretching and eventual breakage of the flexible rubber hose attached to the delivery system, severing it at the sea bed level.
Consequently, diesel oil spilled into the sea (spillage) and, due to an open storage tank gate valve at Caltex’s depot, diesel oil previously discharged backflowed into the depot storage.

The vessel crew’s attempts at water flushing failed to avert the loss, and delayed communication (owing in part to the absence of a pump boat) further complicated the situation until Caltex’s gauger and assistant surveyor intervened.
The quantitative losses were recorded as:

AHAC, acting as Caltex’s subrogee, initiated two separate civil actions against Delsan in 1985:

Civil Case No. 85-29357 (for the spillage loss) seeking recovery of P479,262.57 plus legal interest and attorney’s fees.
Civil Case No. 85-30559 (for the backflow loss) seeking recovery of P1,939,575.37 along with attorney’s fees.

Both cases were consolidated and assigned to Branch 9 of the Manila Regional Trial Court (RTC).
On August 31, 1989, the RTC rendered a decision in favor of AHAC, holding Delsan liable for negligence in its duty as a common carrier, and awarding damages with attorney’s fees.
Delsan subsequently appealed to the Court of Appeals (CA) in CA-G.R. CV No. 40951, where the CA affirmed the RTC’s findings with a minor modification – specifically deleting the award for attorney’s fees.

Delsan contended that the CA erred by ruling that Article 1734 of the Civil Code (enumerating exceptions to a common carrier’s liability) did not exonerate it from liability.
It further argued that the CA failed to apply the rule on contributory negligence against Caltex, the shipper-owner of the cargo.
Additionally, Delsan maintained that the loss due to backflow should not be its responsibility because the diesel oil had already been delivered to Caltex at the time the incident occurred.

The CA upheld the findings of the trial court, noting that the discharging of the cargo had not been completed at the time of the incident—hence, there was no effective delivery to Caltex.
Both the trial court and the CA found that Delsan had failed to prove any contributory negligence on Caltex’s part or to establish that the loss occurred after complete delivery.
Upon review, the Supreme Court (via this petition for review on certiorari) denied Delsan’s petition, affirming in toto the CA decision, and held Delsan liable for the loss due to its failure to exercise the extraordinary diligence expected of a common carrier.

Whether Delsan, as a common carrier, exercised the extraordinary diligence required in the transport and discharge of the diesel oil cargo.
Whether the application of Article 1734 of the Civil Code, with its exceptions to a carrier’s liability, could exonerate Delsan from liability for the loss suffered.
Whether there was any contributory negligence on the part of Caltex (the shipper-owner) that could mitigate or negate Delsan’s liability.
Whether the diesel oil loss through backflow fell within the ambit of cargo delivery to Caltex, thereby shifting the responsibility away from Delsan.
