LAWS 3504 Lecture 2: 4

Business law question:

Assume that a state statute gives someone doing repairs a possessory artisan's lien on the property repaired. Mr. Baker took his car into Mack's Garage for repair but, being strapped for funds, couldn't pay the full bill, and Mack wouldn't let him have the car back. Is Mack's artisan's lien an article 9 security interest? If, prior to the repair work, Mr. Baker signed a statement giving Mack's garage a right to repossess the car if the bill wasn't paid, does this agreement create a security interest under the Code?
