Artikel 17

1. If it becomes evident, after the goods have been taken over by the carrier, that carriage or delivery cannot be performed according to the contract, the carrier shall ask for instructions from the person entitled or, where circumstances prevent delivery, from the consignor. In derogation from sentence 1, the carrier shall ask for instructions from the consignee if it becomes evident, after the goods have reached the country of destination, that the carriage cannot be performed according to the contract of carriage.
2. If the consignee has given the instruction to deliver the goods to another person, paragraph 1 of this Article shall apply as if the consignee were the consignor and the other person were the consignee.
3. If circumstances preventing carriage can be avoided by modifying the route, the carrier shall decide whether a modification shall be made or whether it is in the interest of the person entitled to ask him for instructions.
4. If circumstances preventing delivery cease to exist before arrival of instructions from the consignor to the carrier, the goods shall be delivered to the consignee. The consignor shall be notified without delay.
