On-the-Spot Question

Why do you think the Court of Appeal held that there was a unilateral offer in Carlill v Carbolic Smokeball Co? Can you distinguish this case from Partridge v Crittenden?

View the Answer

Answer

The Court of Appeal held that there was a unilateral offer in Carlill v Carbolic Smoke Ball Co [1863] 1 QB 256 because there was a clear intention to be bound by the promise to pay 100l. to anyone who used the smoke ball but still contracted influenza. This intention to be bound was evidenced by the deposit of 1,000l. in the bank. The case of Partridge v Crittenden [1968] 1 WLR 1204 can be distinguished as there was no such clear intention to be bound to the first person to answer the advertisement evidenced in this case.

On-the-spot Question

Fred has lost his tap shoes and puts up notices in the West End offering £50 to anyone who finds them. Fred later decides to buy another pair and so decides to revoke his offer. He removes the old notices and puts up several new notices announcing the revocation. Ginger has previously seen the offer and finds Fred’s tap shoes. She is a fan of Fred and is so excited to see him that she forgets to ask for the reward.

Advise Ginger.

Answer

The first issue in this question is whether Fred’s initial notice constitutes an invitation to treat or an offer. Applying cases such as Williams v Carwardine (1833) 4 B & Ad 621 and Carlill v Carbolic Smoke Ball Co [1863] 1 QB 256, the notice is likely to demonstrate sufficient intention to be bound, thus it may be a unilateral offer. An offer can only usually be revoked by communicating this to the offeree before acceptance (Byrne & Co v Leon Van Tienhoven & Co(1879–80) LR 5 CPD 344). If so, Fred can only revoke his offer in the same way in which the offer was made (Shuey v US [1975] 92 US 73).

On-the-spot Question

Mohammed meets Sandra on Monday in the supermarket and he offers to sell her his car for £3,000. Sandra asks whether he might consider a slightly lower price. Mohammed shakes his head and then says that the offer is open until 5pm on Friday. Sandra is unsure as to whether Mohammed lives at number 34 or 56 Shakespeare Drive and decides to send a letter accepting his offer to number 34. Sandra doesn’t watch the news and is unaware that there is a seven-day postal strike starting tomorrow. Sandra posts the letter on Monday at 4pm. Mohammed changes his mind and decides to telephone Sandra informing her of this fact. He leaves a message on her answerphone at 4.05pm on that Monday. Sandra never checks her answerphone. On Thursday, Sandra bumps into Mohammed at the chemist and informs him, ‘I’ve accepted your offer’; however, Mohammed is listening to his MP3 player and does not hear her.

Advise Sandra as to whether there is a binding contract between her and Mohammed.

Answer

  • Mohammed has made Sandra an offer to sell her his car for £3,000. It is a valid offer because it is clear and precise. It must be clear that the offeror intended for his statement to constitute an offer, which, if accepted by the offeree, would constitute a binding agreement. This means that the offer must be sufficiently certain and capable of being binding on the offeror. Here, this requirement is satisfied.
  • The question is whether Sandra asking Mohammed if he would accept a lower price amounts to a counter-offer (which will kill off the original offer: Hyde v Wrench (1840) 49 ER 132) or a request for further information (which will not kill off the original offer: Stevenson, Jacques & Co v McLean (1879–80) LR 5 QBD 346).
  • Mohammed states that the offer is open until 5pm on Friday.
  • On Monday at 4pm, Sandra purports to accept Mohammed’s offer. The acceptance must mirror the offer. This means that the acceptance must be a clear and unequivocal mirror image of the terms of the offer. There cannot be differences between the terms offered and those accepted. Presumably Sandra’s acceptance mirrors the terms of Mohammed’s offer.
  • Sandra’s acceptance must be communicated to Mohammed. Crucially, the offeree must communicate his acceptance to the offeror (this is known as the ‘receipt rule’). Until acceptance is communicated, the offeror is free to revoke his offer. See Entores Ltd v Miles Far East Corp [1955] 2 QB 327. This means that acceptance does not take place until Mohammed actually receives Sandra’s acceptance. However, there are a number of exceptions to this and the relevant one here is the postal rule – where the offeree sends his acceptance by post, acceptance is regarded as having taken place when the letter is posted, and not when the letter actually reaches the offeror (see Adams v Lindsell (1818) 1 B & Ald 681).
  • Students must ask whether it was reasonable for Sandra to use the post to send her acceptance. However, she has possibly sent the letter to the wrong address. Where the letter is posted to the wrong address, the postal rule does not apply – see Korbetis v Transgrain Shipping BV [2005] EWHC 1345 (QB).
  • If the postal rule applies then the offer is accepted when Sandra posts the letter and, therefore, any subsequent revocation of the offer by Mohammed will be ineffective.
  • Mohammed attempts to revoke his offer by leaving Sandra a voicemail at 4.05pm on Monday. Revocation actually must be communicated to the offeree in order for it to be effective. But here Sandra has not checked her voicemail, so when would receipt of Mohammed’s revocation take place? This would be a point of discussion for students.
  • On Thursday, Sandra again purports to accept Mohammed’s offer. Acceptance must be communicated and, here, Mohammed cannot hear Sandra’s acceptance. Consider Entores Ltd v Miles Far East Corp [1955] 2 QB 327 to determine whether acceptance could take place here.
