Charlie enters a music store in a shopping centre. Brian, who owns and operates the store, has placed the following sign in the store window:
Special Offer
The Beatles – Abby Road
Only $10 each
Charlie, who operates a competing music store in another shopping centre, realises that he easily can sell this great CD for $20 in his store. Charlie collects all the copies of the relevant CD and brings them to the cash register. Brian knows that Charlie is a competitor and refuses to sell the
CDs to Charlie. However, having been told by Charlie that there is a binding contract since he has accepted Brian’s offer, Brian gives up and sells the CDs to Charlie.
Two hours later Mick enters the shop saying that he accepts the offer and that he wants a CD. When Brian explains that he has no more copies of the CD, Mick argues there is already a binding contract, since he has accepted Brian’s offer.

(b)
(c)
(d)
In your opinion, was Charlie correct in claiming a right to buy the CDs?
Does Mick now have a right to sue Brian for breach of contract?
Do you think it would make any difference, in relation to Charlie’s situation, if there was no sign at all, but the CDs’ price tag stated the price of $10?
Do you think it would make any difference if the sign outside the shop said:
Special Offer
The Beatles – Abby Road
$10 each, 100 CDs in stock

Billy offered to sell his car to Jimmy for $5000 and stated that he would assume that Jimmy had accepted his offer unless he informed Billy to the contrary within 10 days.

Traditionally: The mirror image rule
Reform:
Under the UCC 2-207(1) – a definite expression of acceptance or a written confirmation of an informal agreement may constitute a valid acceptance even if it states terms additional to or different from the offer or informal agreement.
The additional or different terms are treated as proposals for addition into the contract under
UCC 2-207(2), such as between merchants, such terms become part of the contract unless : (a) the offer expressly limits acceptance to the terms of the offer, (b) material alteration of the contract results. (c) Notification of objection to the additional/different terms are given in a reasonable time after notice of them is received.

Material Alternation:
 A change in the subject matter, quantity, quality, price or remuneration, time ,place and method of performance, liabilities for breach of contract or method of dispute resolution is a material change to the terms of the offer.

A indicates 31 March as the deadline for acceptance of its offer. B’s acceptance reaches A on 3 April.
1) Is this acceptance effective?
2) A, who is still interested in the contract, intends to “accept”
B’s late acceptance, and immediately informs B of its intention. Is the acceptance effective?
3) If B knowing that the normal time for transmission of letters by mail to A is three days,B sends its letter of acceptance on 25 March. Owing to a strike of the postal service in A’s country the letter, which shows the date of its mailing on the envelope, only arrives on 3 April. Is B’s acceptance effective? What if A objects without undue delay?

 (1) A late acceptance is nevertheless effective as an acceptance if without undue delay the offeror so informs the offeree or gives notice to that effect.
 (2) If a communication containing a late acceptance shows that it has been sent in such circumstances that if its transmission had been normal it would have reached the offeror in due time, the late acceptance is effective as an acceptance unless, without undue delay, the offeror informs the offeree that it considers the offer as having lapsed.

 William E. Story and his nephew, William E.
Story II, agreed that the uncle would pay his nephew $5000 if the nephew would refrain from drinking, using tobacco, swearing, and playing cards and billiards for money until he turned 21.
The nephew accepted it and did so until his 21 years old. When the nephew turned 21, his uncle sent him a letter indicated that the nephew had earned the $5000. The uncle died later without having transferred the funds to his nephew. The nephew brought suit against the executor of the uncle’s estate, Franklin Sidway.
 Question: Is there a sufficient consideration to create a valid and enforceable contract in this case?

 Does something (an act) or promise to do something he or she is not legally bound to do.
 Refrains (from an act) or promises to refrain from doing something she or he has a legal right to do.

- a misunderstanding about a material fact by the parties a) Common mistake
Party A thinks that X is Y, Party B thinks that X is Y, and they entered into a contract based on the fact that X is Y. But actually X is Z.
only if the mistake of the subject-matter was sufficiently fundamental to render its identity different from what was contracted, making the performance of the contract impossible. ( Bell v
Lever Brothers Ltd )

b) Mutual mistake
A think X is Y, but B think X is Z, A and B enter into a contract for selling X without knowing each other’s misunderstanding

Raffles (P) contracted to sell 125 bales of Surat cotton to
Wichelhaus (D). The goods were to be shipped from
Bombay to Liverpool, England on the ship “Peerless”.
Neither party was aware that there were two ships names
“Peerless” carrying cotton from Bombay to Liverpool, one arriving in October and the other in December.
Wichelhaus thought he had purchased the cotton arriving on the October ship, but Raffles sent his cotton on December ship. Wichelhaus refused to accept delivery of the cotton arriving on the December ship and Raffles brought this lawsuit for breach of contract.
Issues
 If a latent ambiguity arises that shows that there had been no meeting of the minds, have the parties given mutual assent to contract?

c) Unilateral mistake
Part A think X is Y, Party B think X is Z, the fact is X is Z not Y, This contract is entered into based on Party A’s unilateral mistake.
Generally, unilateral mistake can not be a ground to rescind a contract, unless
 it is unconscionable to enforce the contract
 the mistake is leaded by the fault or carelessness of another party

 China contract law – ARTICLE 54 – a party may petition the
People’s Court or an arbitration institution for amendment or cancellation of a contract if the contract was concluded as a result of serious misunderstanding .

(Relevant mistake)
(1) A party may only avoid the contract for mistake if, when the contract was concluded, the mistake was of such importance that a reasonable person in the same situation as the party in error would only have concluded the contract on materially different terms or would not have concluded it at all if the true state of affairs had been known, and
(a) the other party made the same mistake, or caused the mistake, or knew or ought to have known of the mistake and it was contraryto reasonable commercial standards of fair dealing to leave the mistaken party in error; or
(b) the other party had not at the time of avoidance reasonably acted in reliance on the contract.
(2) However, a party may not avoid the contract if
(a) it was grossly negligent in committing the mistake; or
(b) the mistake relates to a matter in regard to which the risk of mistake was assumed or, having regard to the circumstances, should be borne by the mistaken party.
