Retained Title Creates Security Interest
Apex Dynamics sold specialized mining equipment to Alpine Mining under a contract that reserved title until full payment. Alpine took delivery and began using the equipment but made no further payments. When Alpine entered receivership, Apex asserted its retained interest to recover the equipment. The court applied Article 2 rules to determine that the reservation of title created an enforceable security interest arising under the sales article.
Ordinary-Course Purchase Protects Buyer
Avalon Pharmaceuticals purchased laboratory chemicals from a regular supplier in the ordinary course of its business without knowledge of any prior security claim. When a secured creditor later asserted rights in the chemicals, Avalon invoked its status as a buyer in ordinary course. Article 2 supplied the definitional framework that shielded Avalon from the prior interest.

Course-of-Performance Evidence Admitted
Alice Atkins contracted with Astra Aerospace for repeated deliveries of specialized fasteners. Over several years Astra accepted orders specifying a particular grade of alloy even though the written contract contained no such term. When a later dispute arose, Alice offered evidence of the parties' consistent prior dealings. The court used Article 2 to admit the course-of-performance evidence to interpret the contract.

Modification Enforceable Without New Consideration
Austin Abbott agreed to supply custom parts to Amber Alonzo at a fixed price. Rising material costs prompted a good-faith price adjustment that Amber accepted in writing. When Amber later refused the higher price, Austin sued. Article 2 rendered the modification binding without fresh consideration because it was sought in good faith.

Mitigation Duty Limits Lost-Profit Claim
Amelia Amari contracted to purchase specialized film equipment from Twentieth Century-Fox but the supplier canceled. It offered her comparable equipment in another transaction that she declined. Amelia sued for the full contract price. Article 2 principles required her to mitigate damages, reducing recovery by the amount she could have saved in the substitute purchase.

Impracticability Excuses Performance

The court examined whether the cost increase was within the parties' contemplation at formation.

Common questions
Frequently Asked
3
When does Article 2 govern a contract that mixes goods and services?+
Article 2 applies to the goods portion of a hybrid transaction. If goods predominate, the entire contract falls under Article 2 while non-goods obligations remain subject to other law. If services predominate, Article 2 still governs disputes concerning the quality or conformity of the goods themselves.
Supporting sources
Does Article 2 apply to a sale-leaseback structured as financing?+
No. When a transaction functions only as a security device rather than a genuine sale of goods, Article 2 does not apply. Courts examine the substance of the arrangement, including whether the seller retains ownership burdens and whether payment terms mirror a loan.
Supporting sources
What remedy is available to a buyer who rightfully revokes acceptance under Article 2?+
A buyer who revokes acceptance may assert a security interest in the goods to the extent of the price paid and incidental expenses. The buyer may then resell the goods after proper notice and apply the proceeds to its claim.
