Warsaw Convention Jurisdiction in International Air Carriage Disputes in the Philippines

Philippine Supreme Court clarifies when the Warsaw Convention applies to international air carriage and which courts have jurisdiction over baggage loss claims.


The Warsaw Convention governs liability for damages in international air transportation, including the loss of checked baggage. A key question in Philippine litigation is whether this international treaty—and its restrictive jurisdictional rules—applies to a particular carriage contract. In Mapa v. Court of Appeals (G.R. No. 122308, July 8, 1997), the Supreme Court addressed this issue and clarified the proper procedure for resolving jurisdictional challenges raised under the Convention.

The Facts of the Case

Purita and Carmina Mapa purchased TWA tickets in Bangkok, Thailand, for travel within the United States: Los Angeles-New York-Boston-St. Louis-Chicago. They had earlier flown from Manila to Los Angeles on Philippine Airlines (PAL) under separate, independently issued tickets. During a domestic leg from New York to Boston, four of their seven checked bags went missing. TWA later paid US$2,560, which the Mapas accepted only as partial payment. They then sued TWA in the Regional Trial Court of Quezon City for the full value of the lost items, plus moral and exemplary damages and attorney's fees.

The Issue

TWA moved to dismiss the case, arguing that Philippine courts lacked jurisdiction under Article 28(1) of the Warsaw Convention. That provision states that an action for damages must be brought, at the plaintiff's option, in the territory of one of the High Contracting Parties, either before the court of the carrier's domicile, its principal place of business, the place of business through which the contract was made, or the place of destination. Since TWA's domicile and principal place of business were in Kansas City, the contract was made in Bangkok, and the destination was Chicago, TWA argued that no Philippine court could hear the case.

The trial court agreed and dismissed the complaint. The Court of Appeals affirmed. The Mapas then appealed to the Supreme Court.

The Supreme Court's Ruling

The Supreme Court reversed the lower courts and remanded the case for trial. The Court's reasoning centered on two points: the proper definition of and the procedural burden on the party invoking a jurisdictional defense.

Definition of international transportation. Under Article 1(2) of the Convention, carriage is argument.** TWA argued that the TWA tickets were issued in conjunction with international tickets for the Manila-Los Angeles leg, making the whole journey a single, undivided international carriage under Article 1(3) of the Convention. However, the Court noted that the alleged international tickets were never presented in evidence, and TWA did not deny that the PAL tickets were independent contracts. The passengers' later notation of their full itinerary on a TWA property questionnaire, made after the loss, could not retroactively alter the terms of the carriage contracts. Without evidence that the parties regarded the Manila-to-Chicago journey as a single operation, the domestic TWA carriage could not be deemed international.

Procedural requirement. The Court emphasized that when a defendant pleads lack of jurisdiction as an affirmative defense, it must prove the factual basis of that defense at a preliminary hearing. Under the Rules of Court, dismissal is proper only if the ground appears to be indubitable. TWA offered no evidence to support its claim that the carriage was international, so the trial court should have denied the motion and proceeded to trial on the merits.

Practical Takeaways

  • The Warsaw Convention applies only to as defined in Article 1(2)—determined strictly by the contract of carriage, not by the passenger's actual travel plans or later statements.
  • A domestic flight within one country does not become international merely because it connects with an international flight, unless the parties regarded the entire journey as a single operation under a single contract or a series of linked contracts.
  • Article 28(1) of the Convention restricts where an action for damages may be brought: the carrier's domicile, principal place of business, the place where the contract was made, or the place of destination.
  • A defendant raising lack of jurisdiction under the Convention must present evidence at a preliminary hearing; a court may dismiss only if the jurisdictional ground is indubitable.
  • Passengers who believe their carriage is not covered by the Convention should be prepared to show that their tickets were independent contracts, not part of a single international journey.
