Article 18 Montreal Convention
Article 18 of the Montreal Convention (Convention For the Unification of Certain Rules for International Carriage by Air) is titled Damage to Cargo. It is under Chapter III (Liability of the Carrier and Extent of Compensation for Damage).
1. The carrier is liable for damage sustained in the event of the destruction or loss of, or damage to, cargo upon condition only that the event which caused the damage so sustained took place during the carriage by air.
2. However, the carrier is not liable if and to the extent it proves that the destruction, or loss of, or damage to, the cargo resulted from one or more of the following:
(a) inherent defect, quality or vice of that cargo;
(b) defective packing of that cargo performed by a person other than the carrier or its servants or agents;
(c) an act of war or an armed conflict;
(d) an act of public authority carried out in connection with the entry, exit or transit of the cargo.
3. The carriage by air within the meaning of paragraph 1 of this Article comprises the period during which the cargo is in the charge of the carrier.
4. The period of the carriage by air does not extend to any carriage by land, by sea or by inland waterway performed outside an airport. If, however, such carriage takes place in the performance of a contract for carriage by air, for the purpose of loading, delivery or transshipment, any damage
is presumed, subject to proof to the contrary, to have been the result of an event which took place during the carriage by air. If a carrier, without the consent of the consignor, substitutes carriage by another mode of transport for the whole or part of a carriage intended by the agreement between the parties to be carriage by air, such carriage by another mode of transport is deemed to be within the period of carriage by air.
