If the carrier proves that the damage was
caused or contributed to by the negligence or
other wrongful act or omission of the person
claiming compensation, or the person from
whom he or she derives his or her rights, the
carrier shall be wholly or partly exonerated
from its liability to the claimant to the extent
that such negligence or wrongful act or omission
caused or contributed to the damage. When by
reason of death or injury of a passenger
compensation is claimed by a person other
than the passenger, the carrier shall likewise
be wholly or partly exonerated from its liability
to the extent that it proves that the damage was
caused or contributed to by the negligence or
other wrongful act or omission of that
passenger. This Article applies to all the liability
provisions in this Convention, including
paragraph 1 of Article 21.
