Gacal vs. Philippine Air Lines, Inc.

A hijacking that occurs while airport security is under the exclusive control of military authorities during martial law constitutes a caso fortuito or force majeure that exempts the common carrier from liability for resulting death, personal injuries, and loss of baggage, provided the carrier had no participation in the event and the event made normal performance of its obligation impossible.

On May 21, 1976, Franklin G. Gacal, his wife Corazon M. Gacal, Bonifacio S. Anislag and his wife, and Elma de Guzman boarded a PAL BAC 1-11 aircraft at Davao Airport for a flight to Manila. Six other passengers—members of the Moro National Liberation Front (MNLF) from Marawi City—carried concealed grenades and pistols aboard the same flight. Ten minutes after takeoff, the six announced a hijacking. The pilot explained the aircraft’s fuel limits prevented a flight to Libya or Sabah, so the hijackers directed a landing at Zamboanga Airport for refueling. The plane landed at 3:00 p.m. and was met by military armored cars. The hijackers demanded a DC-aircraft to Libya, the PAL president as hostage, $375,000, and six armalites, threatening to blow up the plane. Passengers received only minimal food and water over two days. After relatives of the hijackers boarded and alighted, an armored car bumped the stairs, triggering a firefight between the military and the hijackers. The battle left ten passengers and three hijackers dead; three hijackers were captured. Corazon Gacal was injured while jumping from the plane after grenades exploded and gunfire struck the aircraft; she was hospitalized. The Gacals’ personal belongings were lost. Franklin Gacal was unhurt. The Gacals sued PAL for damages, alleging gross negligence in failing to frisk passengers adequately to detect hidden weapons and for not using metal detectors despite the known risk of skyjacking.

• The Hijacking Incident: On May 21, 1976, petitioners and other passengers boarded PAL’s BAC 1-11 at Davao Airport for a Manila flight. Six co-passengers—MNLF members from Marawi City—were armed with three grenades, two .45 caliber pistols, and one .22 caliber pistol. Ten minutes after takeoff, the hijackers brandished their weapons, ordered the pilot to fly to Libya, then Sabah, but relented after the pilot explained fuel limitations, directing the aircraft to land at Zamboanga Airport for refueling. The plane landed at 3:00 p.m. and was met by two military armored cars with machine guns aimed at the aircraft. The hijackers demanded a DC-aircraft to Libya, the PAL president as hostage, $375,000, and six armalites, and threatened to blow up the plane. Passengers received no food or water until May 23, when they were given a quarter-slice of sandwich and a minimal amount of water.

• The Military Assault: After relatives of the hijackers boarded and then alighted, an armored car bumped the aircraft stairs. A battle erupted between the military and the hijackers. Two hand grenades exploded inside the plane and it was peppered with bullets. Ten passengers and three hijackers died on the spot; three hijackers were captured.

• Injuries and Losses: Franklin G. Gacal escaped unhurt, but Corazon M. Gacal was injured while jumping from the plane during the gunfire and explosions. She was hospitalized for two days, incurring P245.60 in medical expenses, and their personal belongings worth P8,995.00 were lost and never recovered. The Gacals sought actual damages, moral damages of P50,000 each, exemplary damages, and attorney’s fees.

• The Military Takeover of Airport Security: Evidence established that on October 20, 1973, General Jose L. Rancudo, Commanding General of the Philippine Air Force, announced a military takeover of airport security, including the frisking of passengers and inspection of luggage for domestic and international flights. This takeover was confirmed shortly before the hijacking by Letter of Instruction No. 399 issued on April 28, 1976. At the time of the incident, security checks at Davao Airport were performed exclusively by military personnel; PAL had no role in or control over passenger screening.

• Gross Negligence: Petitioners argued that PAL’s failure to frisk passengers adequately, and its failure to use metal detectors despite the prevalence of skyjacking, constituted gross, wanton, and inexcusable negligence that directly caused the hijacking and the resulting injuries and losses.
• Breach of Extraordinary Diligence: They maintained that as a common carrier, PAL breached its contractual obligation to carry passengers safely by not exercising the extraordinary diligence required under the Civil Code.

• Fortuitous Event: PAL countered that the hijacking was a force majeure—an extraordinary event that was unforeseeable, unavoidable, and beyond its control—and that this exempted it from any liability for damages.
• Military Control of Security: PAL averred that security checks, frisking of passengers, and baggage inspection at Davao Airport were performed solely by military personnel pursuant to official authority that had assumed exclusive jurisdiction over airport security; consequently, any failure in screening could not be attributed to PAL. The negotiations with hijackers and the military operation were likewise purely government matters beyond PAL’s control.

• Force Majeure: Whether the hijacking incident, occurring during martial law when the military had exclusively taken over airport security, constituted a caso fortuito or force majeure that exempted PAL from liability for damages to its passengers.

• Force Majeure: The hijacking was a caso fortuito that exempted PAL from liability. Under Article 1174 of the Civil Code, a fortuitous event must meet four requisites: (a) the cause of the breach must be independent of the obligor’s will; (b) the event must be unforeseeable or unavoidable; (c) it must render normal performance of the obligation impossible; and (d) the obligor must be free from any participation in or aggravation of the injury. All four elements were satisfied. The hijacking was staged by MNLF members with no connection to PAL, making the cause independent of PAL’s will. Although a hijacking might ordinarily be foreseeable and preventable through thorough frisking under Republic Act No. 6235, the military had taken over and exercised exclusive control over airport security during martial law, as announced in 1973 and confirmed by Letter of Instruction No. 399 shortly before the incident. This takeover removed PAL from the security screening process, rendering the hijacking unavoidable for PAL and making it impossible for PAL to perform its carriage obligation in a normal manner. PAL did not participate in or aggravate the injury. Because PAL established all elements of force majeure, the presumption of negligence was overcome and the dismissal of the damage suit was properly affirmed.

• Force Majeure in Common Carrier Liability — To exempt a common carrier from liability for breach of its obligation by reason of a fortuitous event, the carrier must prove the concurrence of four elements: (1) the cause of the breach is independent of the obligor’s will; (2) the event is either unforeseeable or unavoidable; (3) the event renders it impossible for the obligor to fulfill the obligation in a normal manner; and (4) the obligor is free from any participation in, or aggravation of, the injury. The Court applied the doctrine to an airline hijacking during martial law, holding that the military’s exclusive takeover of passenger screening made the hijacking unavoidable for the carrier and severed any causal link between the carrier’s conduct and the incident.

• Extraordinary Diligence of Common Carriers — Common carriers are bound to carry passengers safely as far as human care and foresight can provide, exercising the utmost diligence of a very cautious person. They are presumed negligent when a passenger dies or is injured, and must overcome this presumption by showing they observed extraordinary diligence or that the accident was caused by a fortuitous event.

• “In order to constitute a caso fortuito or force majeure that would exempt a person from liability under Article 1174 of the Civil Code, it is necessary that the following elements must concur: (a) the cause of the breach of the obligation must be independent of the human will (the will of the debtor or the obligor); (b) the event must be either unforeseeable or unavoidable; (c) the event must be such as to render it impossible for the debtor to fulfill his obligation in a normal manner; and (d) the debtor must be free from any participation in, or aggravation of the injury to the creditor.” — This passage articulates the controlling four-part test for force majeure under Philippine civil law.

• “Under normal circumstances, PAL might have foreseen the skyjacking incident which could have been avoided had there been a more thorough frisking of passengers and inspection of baggages as authorized by R.A. No. 6235. But the incident in question occurred during Martial Law where there was a military take-over of airport security including the frisking of passengers and the inspection of their luggage preparatory to boarding domestic and international flights.” — This excerpt captures the pivotal factual shift that transformed an otherwise foreseeable risk into an unavoidable caso fortuito.

• Lasam v. Smith, 45 Phil. 657 (1924) — Established the elements of caso fortuito and the principle that no person is responsible for events that could not be foreseen or, if foreseen, were inevitable; followed as the foundational authority for the force majeure test.
• Estrada v. Consolacion, 71 SCRA 523 (1976) — Applied the rule that a common carrier may avoid liability by proving a fortuitous event; cited to reinforce the applicable standard.
• Philippine Airlines, Inc. v. National Labor Relations Commission, 124 SCRA 583 (1983) — Affirmed that common carriers are presumed negligent when a passenger dies or is injured; used to frame the presumption that PAL had to overcome.
• Eastern Shipping Lines, Inc. v. Intermediate Appellate Court, 150 SCRA 463 (1987) — Reiterated the presumption of negligence for loss or deterioration of goods transported by a common carrier.
• Republic v. Luzon Stevedoring Corporation, 21 SCRA 279 (1967) — Clarified that mere difficulty in foreseeing an event does not amount to impossibility; distinguished because here the military takeover made the hijacking impossible for PAL to prevent.

• Article 1733, Civil Code — Requires common carriers to exercise extraordinary diligence for the safety of passengers and goods. The Court applied the consequent presumption of fault against PAL, which was rebutted by proof of force majeure.
• Article 1174, Civil Code — Exempts a debtor from liability for fortuitous events that could not be foreseen, or which though foreseen, were inevitable. The four-element test was drawn from this provision and determined the carrier’s non-liability.
• Article 1734, Civil Code — Enumerates cases where a common carrier is presumed negligent for loss, destruction, or deterioration of goods; referenced in the discussion of the presumption of negligence.
• Republic Act No. 6235 — Authorized thorough frisking of passengers and inspection of baggage. The Court noted that under normal circumstances, PAL could have used such measures to prevent the hijacking, but was precluded from doing so by the military takeover.
