This section clarifies that if a party ignores an obligation under the agreement or authorizes it to break it, this does not mean that party waives its future rights to enforce the same (or other) obligations. This section should clarify that neither the consignor nor the consignee may delegate their obligations under the contract without the prior authorisation of either party. For the shipper, whether it is a person or a company, a shipping contract is necessary, because it ensures his possession of the products shipped. Consignment makes it superfluous to sell products on the basis of invoices. For the shipper, it would also be harmful, especially if the goods have a highly valued value, that the consignee might not be able to pay the shipper until the goods are sold to the customer. . . .
