Jubedul lets his office know that he is selling his pet cat Bianca for £50, and that if anyone would like to buy her they should let him know. Liz, his co-worker, sends him a letter containing £50, saying that she will buy Bianca. However, she puts the wrong address on the envelope and the letter never arrives. Has Liz accepted Jubedul's offer?
Incorrect. The postal rule provides that a posted acceptance is valid from the moment it is posted, even if it arrives late or never arrives at all: Adams v Lindsell. However, the postal rule does not apply if it is the offeree's fault that the letter did not arrive: LJ Korbetis v Transgrain Shipping. Liz's letter did not arrive because she put the wrong address on the envelope, so it is her fault it did not arrive. She has therefore failed to communicate her acceptance to Jubedul.
