Case 1: Donoghue V Stevenson (1932)
Case 2: Daniels V White (1938)
Two friends enter a cafe, one orders ginger beer. After pouring the last remain, out came out a decomposed snail. The women sued the manufacturer and unsurprisingly won the case.
The claiment bought a bottle of lemonaide and when she drank it, she felt a burning sensation in her throat. The bottle was examined and was found to contain a corrosive chemical.
These two cases are example of Judicial Precedent, though the cases were infact slightly different, they contained similar situations.
