5.2       If an insured item is partially rifled or partially damaged, the sender shall be entitled to an indemnity corresponding, in principle, to the actual value of the theft or damage. It may, however, in no case exceed the amount of the insured value in SDRs.

6. In the cases mentioned in 4 and 5, the indemnity shall be calculated according to the current price, converted into SDRs, of articles or goods of the same kind at the place and time at which the item was accepted for conveyance. Failing a current price, the indemnity shall be calculated according to the ordinary value of articles or goods whose value is assessed on the same basis.
7. When an indemnity is due for the loss of, total theft from or total damage to a registered item, ordinary parcel or insured item, the sender, or the addressee, as the case may be, shall also be entitled to repayment of the charges and fees paid with the exception of the registration or insurance charge. The same shall apply to registered items, ordinary parcels or insured items refused by the addressee because of their bad condition if that is attributable to the postal service and involves its liability.
8. Notwithstanding the provisions set out under 2, 4 and 5, the addressee shall be entitled to the indemnity after delivery of a rifled or damaged registered item, ordinary parcel or insured item.
9. The postal administration of origin shall have the option of paying senders in its country the indemnities prescribed by its internal legislation for registered items and uninsured parcels, provided that they are not lower than those laid down in 2.1 and 4.1. The same shall apply to the postal administration of destination when the indemnity is paid to the addressee. However, the amounts laid down in 2.1 and 4.1 shall remain applicable:

9.1       in the event of recourse against the administration liable; or

9.2       if the sender waives his rights in favour of the addressee or vice versa.

10. No reservations concerning payment of the indemnity to postal administrations may be made to this article, except in the event of bilateral agreement.

Article 22

Non-Liability of Postal Administrations

1. Postal administrations shall cease to be liable for registered items, recorded delivery items, parcels and insured items which they have delivered according to the conditions laid down in their regulations for items of the same kind. Liability shall, however, be maintained:

1.1       when theft or damage is discovered either prior to or at the time of delivery of the item;

1.2       when, internal regulations permitting, the addressee, or the sender if it is returned to origin, makes reservations on taking delivery of a rifled or damaged item;

1.3       when, internal regulations permitting, the registered item was delivered to a private mail-box and the addressee declares that he did not receive the item;

1.4       when the addressee or, in the case of return to origin, the sender of a parcel or of an insured item, although having given a proper discharge, notifies the delivery administration without delay that he has found theft or damage. He shall furnish proof that such theft or damage did not occur after delivery. The term “without delay” shall be interpreted according to national law.

2. Postal administrations shall not be liable:

2.1       in cases of force majeure, subject to article 13.6.9;

2.2       when they cannot account for items owing to the destruction of official records by force majeure, provided that proof of their liability has not been otherwise produced;

2.3       when such loss, theft or damage has been caused by the fault or negligence of the sender or arises from the nature of the contents;

2.4       in the case of items that fall within the prohibitions specified in article 15;

2.5       when the items have been seized under the legislation of the country of destination, as notified by the administration of that country;

2.6       in the case of insured items which have been fraudulently insured for a sum greater than the actual value of the contents;

2.7       when the sender has made no inquiry within six months from the day after that on which the item was posted;

2.8       in the case of prisoner-of-war or civilian internee parcels;

2. In the case of damage to other postal items, the sender shall be liable for each item damaged within the same limits as postal administrations.
3. The sender shall remain liable even if the office of posting accepts such an item.
4. However, where the conditions of acceptance have been observed by the sender, the sender shall not be liable, in so far as there has been fault or negligence in handling the item on the part of administrations or carriers, after acceptance.

Article 24

Payment of Indemnity

1. Subject to the right of recourse against the administration which is liable, the obligation to pay the indemnity and to refund the charges and fees shall rest either with the administration of origin or with the administration of destination.
2. The sender may waive his rights to the indemnity in favor of the addressee. Conversely, the addressee may waive his rights in favor of the sender. The sender or the addressee may authorize a third party to receive the indemnity if internal legislation allows this.

Article 25

Possible Recovery of the Indemnity from the Sender or the Addressee

1. If, after payment of the indemnity, a registered item, a parcel or an insured item or part of the contents previously considered as lost is found, the sender or the addressee, as the case may be, shall be advised that the item is being held at his disposal for a period of three months on repayment of the amount of the indemnity paid. At the same time, he shall be asked to whom the item is to be delivered. In the event of refusal or failure to reply within the prescribed period, the same approach shall be made to the addressee or the sender as the case may be, granting that person the same period to reply.
2. If the sender and the addressee refuse to take delivery of the item or do not reply within the period provided for in paragraph 1, it shall become the property of the administration or, where appropriate, administrations which bore the loss.
3. In the case of subsequent discovery of an insured item the contents of which are found to be of less value than the amount of the indemnity paid, the sender or the addressee, as the case may be, shall repay the amount of this indemnity against return of the item, without prejudice to the consequences of fraudulent insurance.

Article 26

Reciprocity Applicable to Reservations Concerning Liability

1. Notwithstanding the provisions in articles 22 to 25, any member country which reserves the right not to pay indemnity for liability shall not be entitled to receive indemnity from other member countries which accept liability under these articles.
