Module V first-look: who proves what when language is unclear
Floor. ~40 min: R2d § 201 + Frigaliment. The doctrine the next class assumes you have covered.
Target. ~75 min: Floor + Peerless + R2d § 202 + synthesis.
Before a court resolves a meaning dispute, it asks one threshold question: is the term reasonably susceptible to more than one meaning?
(1) Where the parties have attached the same meaning to a promise or agreement or a term thereof, it is interpreted in accordance with that meaning.
(2) Where the parties have attached different meanings to a promise or agreement or a term thereof, it is interpreted in accordance with the meaning attached by one of them if at the time the agreement was made
(a) that party did not know of any different meaning attached by the other, and the other knew the meaning attached by the first party; or
(b) that party had no reason to know of any different meaning attached by the other, and the other had reason to know the meaning attached by the first party.
(3) Except as stated in this Section, neither party is bound by the meaning attached by the other, even though the result may be a failure of mutual assent.
(1) Words and other conduct are interpreted in the light of all the circumstances, and if the principal purpose of the parties is ascertainable it is given great weight.
(2) A writing is interpreted as a whole, and all writings that are part of the same transaction are interpreted together.
(3) Unless a different intention is manifested,
(a) where language has a generally prevailing meaning, it is interpreted in accordance with that meaning;
(b) technical terms and words of art are given their technical meaning when used in a transaction within their technical field.
(4) Where an agreement involves repeated occasions for performance by either party with knowledge of the nature of the performance and opportunity for objection to it by the other, any course of performance accepted or acquiesced in without objection is given great weight in the interpretation of the agreement.
(5) Wherever reasonable, the manifestations of intention of the parties to a promise or agreement are interpreted as consistent with each other and with any relevant course of performance, course of dealing, or usage of trade.
In the interpretation of a promise or agreement or a term thereof, the following standards of preference are generally applicable:
(a) an interpretation which gives a reasonable, lawful, and effective meaning to all the terms is preferred to an interpretation which leaves a part unreasonable, unlawful, or of no effect;
(b) express terms are given greater weight than course of performance, course of dealing, and usage of trade, course of performance is given greater weight than course of dealing or usage of trade, and course of dealing is given greater weight than usage of trade;
(c) specific terms and exact terms are given greater weight than general language;
(d) separately negotiated or added terms are given greater weight than standardized terms or other terms not separately negotiated.
Once a term clears the threshold, courts resolve it on a ranked ladder — intrinsic first, extrinsic only if intrinsic fails.
Intrinsic: plain meaning → specific/defined terms → structure.
Extrinsic: course of performance → course of dealing → trade usage → preliminary negotiations.
Frigaliment walks exactly this ladder: the contract text, then the German term "Huhn," then the USDA regulations, then trade usage, then market price. None alone resolved it — so the burdened party lost.
190 F. Supp. 116 (S.D.N.Y. 1960)
United States District Court for the Southern District of New York
Rule. The party asserting a narrower meaning for an ambiguous term bears the burden of proving that meaning by the preponderance of the evidence; trade usage, dictionary definitions, regulatory definitions, and course of dealing inform but do not by themselves resolve the ambiguity.
2 Hurl. & C. 906, 159 Eng. Rep. 375 (Ex. 1864)
Court of Exchequer
Rule. Where two parties attach materially different meanings to a critical term and neither has reason to know of the other's meaning, no contract is formed for want of mutual assent.
89 F.4th 388 (2d Cir. 2023)
United States Court of Appeals for the Second Circuit
Facts. A marine cargo policy listed an "Approved Location" as "Chamad Warehouse, Inc., 56 Branch Street, Brooklyn, NY." Three warehouse buildings sat at that address. Fire destroyed goods in the second (rear) building. The insurer argued "Approved Location" meant only the primary warehouse fronting the street; the insured argued it covered the whole parcel.
Issue. Is "Approved Location" ambiguous, and if so, what kind?
Analysis. The phrase names a single street address but does not say which buildings it covers. It reads clearly on its face yet splits only when applied to a multi-building parcel — a latent ambiguity. The insurer's best clarity argument: had the parties meant all structures, they would have said "all buildings at 56 Branch Street." The insured's: the address is a legal parcel, not a single building, and ambiguities in insurance policies are construed against the insurer (contra proferentem).
Facts. Buyer''s insurance policy covers loss at the "Approved Location: 56 Branch St., Brooklyn." Buyer stores inventory in three warehouses at that street address: a front building, a rear building, and a side annex. Fire destroys inventory in the rear building. Insurer claims "Approved Location" means only the front building; Buyer claims it means the whole 56 Branch St. parcel.
Question. Is "Approved Location" ambiguous? If so, who bears the burden, and what evidence resolves it?
Answer. R2d § 201 + Frigaliment: the term is reasonably susceptible to both readings, so it is ambiguous (latent: the ambiguity emerges only when you apply the term to the actual property). The party asserting the narrower meaning (Insurer) bears the burden. Insurer must produce intrinsic context (other policy terms, defined-terms section) and extrinsic context (insurance trade usage for "approved location," course of dealing) showing the front-building-only reading prevails. Contra proferentem against the drafter (R2d § 206) supplies a tiebreaker for the insured if the burden showing is in equipoise.
Facts. A grain merchant sends a fax order for "100 tons cotton" intending to write "colton," a regional dialect term for cottonseed meal he had used in five prior orders with this seller. Seller ships ginned cotton fiber. Merchant refuses delivery.
Question. Is this a Frigaliment ambiguity case, a Peerless misunderstanding case, or neither?
Answer. Course of dealing under UCC § 1-303 supplies a meaning (colton = cottonseed meal) that the merchant has reason to expect the seller knows. If the seller genuinely understood "cotton" to mean cotton fiber and had no reason to know of the colton usage, this is closer to Peerless. If the seller knew or had reason to know the merchant''s usage, R2d § 20(2)(b) gives the meaning to the merchant. The case turns on what the seller had reason to know. Which meaning appears more reasonable to an outsider is irrelevant.

Rules. R2d § 201, R2d § 202, R2d § 203.
Cases. Frigaliment Importing Co. v. B.N.S. International Sales Corp. · Raffles v. Wichelhaus.
Open question. Once a court declares a term ambiguous and assigns the burden, what evidence may the burdened party use? Intrinsic only (the contract's four corners) or extrinsic (negotiations, usage, course of dealing)? Next class: intrinsic evidence and the canons of construction.
