"Carlill v Carbolic Smoke Ball Company" (1892) is a landmark case in English contract law and is particularly significant for its contributions to the understanding of contract formation and the principles of offer, acceptance, and consideration. Here's a detailed summary:
- Date: 1892
- Parties: Mrs. Louisa Carlill (Plaintiff) versus Carbolic Smoke Ball Company (Defendant)
- Context: The case arose during the 1890s influenza pandemic, at a time when dubious medical products were common.
- Product and Advertisement: The Carbolic Smoke Ball Company advertised a product called the "Carbolic Smoke Ball," claiming it could prevent influenza. The company offered £100 to anyone who used the smoke ball according to the instructions but still contracted influenza.
- Mrs. Carlill's Actions: Mrs. Carlill purchased the smoke ball, used it as directed, but contracted influenza. She claimed the £100 reward.
- Company's Refusal: The company refused to pay, arguing that the advertisement was not a serious contract offer.
- Claim: Mrs. Carlill sued the company for the £100.
- Issues: The court had to determine whether the advertisement constituted a valid offer that could create a legally binding contract when accepted by someone like Mrs. Carlill.
- Decision: The court ruled in favor of Mrs. Carlill.
- Key Findings:
- Offer: The court held that the advertisement was a unilateral offer to the world at large.
- Acceptance: Mrs. Carlill's use of the product as prescribed constituted acceptance of the offer.
- Consideration: The court found that using the smoke ball as directed was sufficient consideration, as it involved some detriment or inconvenience to Mrs. Carlill.
Legacy and Importance
