Section 9--333. Priority of Certain Liens Arising by Operation of Law.

(a) "Possessory lien." In this section, "possessory lien" means an
interest, other than a security interest or an agricultural lien:

(1) which secures payment or performance of an obligation for

services or materials furnished with respect to goods by a

person in the ordinary course of the person's business;

(2) which is created by statute or rule of law in favor of the

person; and

(3) whose effectiveness depends on the person's possession of the

goods.

(b) Priority of possessory lien. A possessory lien on goods has
priority over a security interest in the goods unless the lien is
created by a statute that expressly provides otherwise.
