George v. Davoli
City Court, City of Geneva, New York
397 N.Y.S.2d 895 (1977)
George (plaintiff) bought jewelry from Davoli (defendant) under a written memorandum allowing a refund if the jewelry proved unacceptable, but the memorandum specified no deadline for returning it; Davoli testified the parties had orally agreed George would have until the following Monday to return it, and when George attempted to return the jewelry the following Wednesday, Davoli refused, prompting suit.
Whether the parol evidence rule bars proof of an oral agreement supplementing a written agreement governed by the UCC where the supplemental term is not inconsistent with the written agreement and the written agreement was not a complete and exclusive expression of the parties' transaction.
