All questions

Question 1

Which of the following is correct?

The seller may rescind because the parties were mistaken about the identity of the painting. (correct answer)
The seller may not rescind because the mistake affected only the painting's market value.
The seller may not rescind because the seller as owner bears the risk of authenticity.
The seller may rescind only if the buyer knew the painting was genuine.

Explanation: Mutual mistake makes a contract voidable if the mistake concerns a basic assumption on which the contract was made and has a material effect on the exchange. The parties' belief that the painting was a copy was a mistake about the very identity of the subject matter, not merely its market value. Because the mistake was material and no risk was allocated, the seller may rescind. B mischaracterizes the mistake as one of value; C invents a risk borne by the owner; D incorrectly requires the buyer's knowledge, which is relevant only to unilateral mistake.

Question 2

Seller offered to sell Buyer a rural parcel for $100,000. Seller chose the price because an old survey led him to believe the parcel contained 100 acres. After the contract was signed, a new survey showed 90 acres. Buyer did not know the acreage and had no reason to know of Seller's mistake. Buyer wanted the land only as a buffer against development, and 90 acres is sufficient for that purpose. Seller discovered the mistake, refused to close, and Buyer sued for specific performance.

Who prevails?

Seller may rescind because the acreage was a basic assumption and the mistake materially affected the exchange.
Seller may rescind because Buyer's acceptance at the listed price showed Buyer had reason to know of the mistake.
Buyer may enforce because Seller's mistake was unilateral, Buyer had no reason to know of it, and enforcement is not unconscionable. (correct answer)
Buyer may enforce only if the reduced acreage still serves the buffer purpose Buyer intended.

Explanation: Seller's mistake about acreage was unilateral because Buyer formed no belief about the acreage and had no reason to know of Seller's error. A unilateral mistake makes a contract voidable only if enforcement would be unconscionable or the other party knew or had reason to know of the mistake. Neither condition is present. Acreage can be a basic assumption, but that alone is insufficient for unilateral mistake. Buyer's purpose is not the legal test, so D is wrong.

Question 3

General Contractor asked Subcontractor to bid on the electrical work for a school. Subcontractor's estimator accidentally omitted a $180,000 switchgear item from its bid, so Subcontractor bid $420,000. The next-lowest bid was $590,000. General Contractor accepted the same day. Its project manager said, 'This is way out of line; they must have made a mistake.' Subcontractor later discovered the omission and refused to perform. General Contractor sued.

Which statement best describes Subcontractor's liability?

Subcontractor is bound because a unilateral mistake by one party never makes a contract voidable.
Subcontractor is bound because General Contractor did not know the precise item omitted.
Subcontractor may avoid because General Contractor had reason to know of the mistake. (correct answer)
Subcontractor may avoid only if enforcing the bid would be unconscionable.

Explanation: Under the rule for unilateral mistake, the mistaken party may avoid the contract if the other party had reason to know of the mistake. A bid far below the next-lowest bid, plus the project manager's explicit remark, gave General Contractor reason to know. Actual knowledge of the precise omitted item is not required. Unilateral mistake can be a ground for avoidance, so the absolute statement in A is wrong. Because General Contractor had reason to know, unconscionability need not be shown, making D wrong.

Question 4

A seller agreed in writing to sell a buyer '10 tons of scrap metal.' The seller meant long tons (2,240 pounds each); the buyer meant short tons (2,000 pounds each). The seller did not know that the buyer used short tons. The buyer, however, knew from prior dealings that the seller always used long tons.

What is the quantity under the contract?

10 long tons, because the buyer knew or had reason to know the seller's meaning. (correct answer)
10 short tons, because the buyer's understanding controls the contract.
No contract, because the parties attached materially different meanings to the word 'ton.'
10 short tons, because ambiguous terms in a contract are construed against the seller.

Explanation: If one party knows or has reason to know the meaning attached by the other, and the other does not know or have reason to know the first party's meaning, the contract is interpreted according to the meaning of the other party. The buyer knew the seller always used long tons, so the seller's meaning controls. B incorrectly favors the buyer; C fails because the buyer's knowledge supplies a meaning; D is a rule of construction that does not override actual knowledge.

Question 5

Buyer and Seller contracted for the sale of 'the cotton cargo arriving on the ship Peerless.' Unknown to both, two different ships named Peerless were scheduled to arrive, one in October and one in December. Seller intended the October cargo; Buyer intended the December cargo. Neither party knew of the other's meaning or that two ships bore the same name, and both meanings were reasonable. Buyer refused the October cargo, and Seller refused to deliver the December cargo.

In a suit between the parties, what is the result?

Seller's meaning controls because the seller may choose the ship it uses to perform the contract.
Buyer's meaning controls because the buyer was the recipient and did not know of the ambiguity.
No contract exists because the parties attached materially different meanings and neither knew or had reason to know of the other's meaning. (correct answer)
The contract is voidable by either party because each party was mistaken about which shipment was sold.

Explanation: When parties attach materially different meanings to a contract term and neither knows or has reason to know of the other's meaning, there is no contract. Here, 'the cotton cargo arriving on the ship Peerless' reasonably referred to two different cargoes, and neither party knew there were two ships with that name. Thus neither party's meaning controls. This is not a case of unilateral mistake or a voidable contract; the manifestation of assent never attached to the same subject matter.

Question 6

A seller agreed to sell, and a buyer agreed to buy, 'all the gravel located in the seller's gravel pit' for $200,000. Neither party had surveyed the pit, and both understood that the quantity of gravel was uncertain. Both nonetheless believed the pit contained at least 50,000 tons. After the contract was signed, a survey showed only 20,000 tons. The buyer wants to avoid the contract.

Should the court allow the buyer to avoid the contract?

Yes, because the parties were mutually mistaken about a fact existing at the time of contracting.
Yes, because the quantity of gravel was central to the buyer's decision to contract.
No, because the buyer treated his limited knowledge of the quantity as sufficient and thus bore the risk. (correct answer)
No, because the buyer's belief about the quantity was not shared by the seller.

Explanation: Under the law of mistake, a party bears the risk of a mistake when he is conscious, at the time of contracting, that he has only limited knowledge of the facts and treats that knowledge as sufficient. Here, both parties knew the gravel pit had not been surveyed and that the quantity was uncertain, yet the buyer priced the contract on an assumed figure. The buyer therefore assumed the risk that the quantity would be less. A and B ignore that risk allocation; D is contrary to the stated facts, which say both parties believed the pit contained at least 50,000 tons.
