§12A-7-307.
   
   (1) A carrier has a lien on the goods covered by a bill of lading for
   charges subsequent to the date of its receipt of the goods for storage
   or transportation (including demurrage and terminal charges) and for
   expenses necessary for preservation of the goods incident to their
   transportation or reasonably incurred in their sale pursuant to law.
   But against a purchaser for value of a negotiable bill of lading a
   carrier's lien is limited to charges stated in the bill or the
   applicable tariffs, or if no charges are stated then to a reasonable
   charge.
   
   (2) A lien for charges and expenses under subsection (1) on goods
   which the carrier was required by law to receive for transportation is
   effective against the consignor or any person entitled to the goods
   unless the carrier had notice that the consignor lacked authority to
   subject the goods to such charges and expenses. Any other lien under
   subsection (1) is effective against the consignor and any person who
   permitted the bailor to have control or possession of the goods unless
   the carrier had notice that the bailor lacked such authority.
   
   (3) A carrier loses his lien on any goods which he voluntarily
   delivers or which he unjustifiably refuses to deliver.
