IRC v Fry: F sent Tax Office a cheque for £10,000 with note telling them to only cash it if they would accept it as full settlement for her debt of £100,000. Tax Office never read the note so offer not valid.
Felthouse v Bindley: Silence is not acceptance. To be valid, acceptance must be communicated.
Yates v Pulleyn: If an offer asks for acceptance in a particular way, it should be by that method or an equally effective one.
Northern Foods v Focal Foods: A first delivery of onions constituted acceptance of an offer so the price could not be negotiated thereafter.
Adams v Lindsell
Household Fire Insurance v Grant: Irrelevant whether offeror ever receives acceptance.
Entores
Thomas v BPE Solicitors: Email received at end of business hours at a solicitor's office. Expectation email would be read during reasonable office hours so acceptance took place when it arrived.
