Adams v Lindsell (1818) 1 B. & Ald. 681
The landmark case of Adams v Lindsell (1818) revolves around the formation of contracts via postal communications, setting a crucial precedent in contract law known as the “postal rule”. The case is fundamental for understanding how contracts are established in scenarios where communication delays are inherent. In this summary you will learn everything you need about this case.
Facts
The defendants wrote to the claimants offering to sell wool and requesting a reply by post. They addressed their offer incorrectly, so it reached the claimants later than expected. The claimants posted an acceptance on the evening the offer arrived. Before that acceptance reached them, the defendants sold the wool to somebody else, believing that no reply would be forthcoming. The acceptance arrived the following day. The claimants brought an action for the failure to deliver the wool. The defendants sought a new trial after the claimants succeeded.
Legal Issue
Was a contract concluded when the claimants posted their acceptance, or only when the defendants received it after selling the wool to another buyer?
Held
The Court of King's Bench upheld the claimants' recovery. The defendants' offer contemplated acceptance through the post, and the claimants had replied without delay after receiving it. Their acceptance therefore completed the contract before the defendants sold the wool elsewhere. The defendants could not rely on a delay caused by their own misdirection of the offer.
The court also recognised the practical difficulty with requiring confirmation that each communication had been received. If acceptance depended on receipt and knowledge of receipt, further confirmations could be demanded indefinitely. Treating the posted acceptance as effective supplied a workable point at which the transaction became binding.
⭐ Legal Principle
Where the postal rule applies, a contract is concluded when a properly posted acceptance is sent, rather than when it reaches the offeror. The rule is an exception to the ordinary requirement that acceptance be communicated and depends on the circumstances and terms of the offer.
Significance
Adams is the starting point for the postal acceptance rule. It helps students separate the time of acceptance from the time the offeror learns of it. The rule should be considered alongside Henthorn v Fraser on contemplated postal communication and Holwell Securities v Hughes on wording requiring notice. Entores concerns substantially instantaneous communication and illustrates why the postal exception should not be applied indiscriminately to other methods.
Common exam questions about this case
When was the contract formed in Adams v Lindsell?
The contract was formed when the claimants posted their acceptance. The offer invited a postal response, and they replied promptly after receiving it. Receipt by the defendants was not required for acceptance to take effect under the postal rule, so the intervening sale breached an existing contract.
Why did the wrongly addressed offer matter?
The defendants' mistake delayed the claimants' opportunity to accept. The claimants were not responsible for failing to reply by the date the defendants expected. That supported the conclusion that the defendants could not treat their own mistaken delivery arrangements as ending the offer before the prompt acceptance was posted.
Does Adams make every posted acceptance effective immediately?
No. First determine whether postal acceptance was contemplated and whether the offer required actual receipt. Holwell Securities illustrates how a requirement for notice can exclude the rule. Adams supplies an exception for appropriate postal dealings, rather than a general rule for every written or electronic communication.
