Question: Priority Disputes. Redford is a seller of electric generators. He purchases a large quantity of generators from a manufacturer, Mallon Corp., by making a down payment and signing an agreement to pay the balance over a period of time. The agreement gives Mallon Corp. a security interest in the generators and the proceeds. Mallon Corp. properly files a financing statement on its security interest. Redford receives the generators and immediately sells one of them to Garfield on an installment contract with payment to be made in twelve equal installments. At the time of the sale, Garfield knows of Mallon's security interest. Two months later, Redford goes into default on his payments to Mallon. Discuss Mallon's rights against purchaser Garfield in this situation.
