What is the case law for English case Adams v Lindsell?

English case law for Adams v Lindsell relates to the issue of when a contract is formed through the exchange of letters. The case established the "postal rule" which states that an acceptance of an offer sent by post becomes effective as a contract when it is posted, regardless of when it is actually received by the offeror. This case is considered a landmark decision in English contract law, as it established the principle that contracts formed by correspondence are formed at the time the acceptance is posted, rather than when it is received.
