5.1 This chapter concerns the position as between the three parties concerned, namely the consignor, the carrier and the consignee, in the period during which the goods are being carried and then on the arrival of the goods. The sort of questions which might arise are such as: who has the right to dispose of the goods while they remain in transit? What is the position of the carrier where those rights of disposal are exercised? Who is entitled to require delivery of the goods? What is the position where performance of the carriage becomes impossible? The Convention deals with issues such as these in Articles 12 to 17.
