Article 50 Liens for charges

A person who by agreement with the Authority collects charges on their behalf and who pays or gives security for the payment of charges on goods in his possession shall have a lien on those goods for the amount paid or security given in respect of them.

A wharfinger or carrier who is not himself liable for the payment of charges may pay or by agreement with the Authority give security for charges on goods in his custody, and in that event he shall have a like lien on the goods for the amount of those charges as he would have in respect of his charges for safe custody or carriage of the goods, as the case may be.
