P.R. Laws tit. 10, § 1795
A carrier who delivers merchandise to a consignee by virtue of agreements or combined services with other carriers shall assume the obligations of the carriers who preceded him, reserving his right to proceed against the latter if he should not be directly responsible for the fault which gives rise to the claim of the shipper or of the consignee.
The carrier making the delivery shall also assume all the actions and rights of those who may have preceded him in the transportation.
The sender and the consignee shall have a right of action against the carrier who executed the transportation contract, or against the other carriers who received the goods transported without reservation.
The reservations made by the latter shall not exempt them, however, from the liabilities they may have incurred by reason of their own acts.
