ORS 79.0333 UCC 9-333

Priority of certain liens arising by operation of law. (1) As used in this section, “possessory lien” means an interest, other than a security interest or an agricultural lien:

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;

Which is created by statute or rule of law in favor of the person; and

Whose effectiveness depends on the person’s possession of the goods.

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.
