(1) The limitation of claims to compensation of damages under a contract for the carriage of general cargo or under a bill of lading for the loss of or physical damage to the goods may be eased or impeded only by an agreement reached after detailed negotiations, whether for one or several similar contracts between the same parties. However, any provision in the bill of lading easing the limitation of claims to compensation of damages is invalid vis-à-vis third parties.
(2) The limitation of claims resulting from personal injuries to persons, physical damage, or delayed re-delivery of luggage as set out in section 606 no. 1 may be extended only by a declaration on the part of the carrier or by an agreement between the parties made after the grounds on which the claim is based have arisen. Both the declaration and the agreement must be made in text form. Any easing of the limitation, specifically a reduction in the prescription period, is not admissible.
