Carlill v Carbolic Smoke Ball
Court of Appeal, England[1893] 1 QB 256Bench: Lindley LJ, Bowen LJ, Smith LJ
An advertisement promising reward upon performance of a specified act constitutes a unilateral offer capable of acceptance by performance. The advertisement was not mere puffery because the company deposited £1,000 with a bank, signalling intention to be bound. Mrs Carlill was entitled to £100.
