- Goods are movable, identified things; services and interests in land are not goods.
- Predominant purpose considers contract language, supplier's business, intrinsic worth of materials, and the transaction's thrust.
- Some courts use a gravamen approach for the particular portion causing injury, but the exam usually signals the governing method.
- UCC rules can modify formation, terms, performance, and remedies, so governing law should be decided first.
Attack sequence
1Classify the transaction and each promised performance.
2Apply predominant purpose to the whole agreement unless instructed otherwise.
3State which body of law governs before applying formation or breach rules.
Traps and exceptions
!A tangible item supplied incidentally during a service does not necessarily convert the agreement into a sale of goods.
!Software and specially manufactured items require attention to facts and the tested rule.
A contractor agrees to design and install a custom heating system; most of the price pays for engineering and labor.
The predominant purpose is likely services, so common law governs despite transfer of equipment. The contract's language, price allocation, and supplier role support that conclusion.
Essay-ready formulationThe predominant purpose of a mixed transaction determines whether common law or Article 2 governs, and that choice controls the remaining analysis.
