Article 7 Liens for charges
(1)
A person who by agreement with the Commissioners collects charges on their behalf and who pays, or gives security for the payment of, charges in respect of goods in his possession shall have a lien on those goods for the amount paid or security given in respect of the goods.
(2)
An operator of a wharf or quay or carrier who is not himself liable for the payment of charges may pay, or by agreement with the Commissioners give security for the payment of, charges in respect of goods in his custody, and in that event he shall have a like lien on the goods for the amount paid or security given in respect of the goods as he would have in respect of his charges for safe custody or, as the case may be, carriage of the goods.
