Which case established the principle of reasonable foreseeability in negligence law?

The principle of reasonable foreseeability in negligence law was established in the landmark case of Donoghue v. Stevenson. This case, decided in 1932, set the foundation for modern negligence law by articulating the "neighbour principle." Lord Atkin famously stated that one must take reasonable care to avoid acts or omissions that could foreseeably injure one's neighbour, which in this context refers to any person who could be directly affected by the actions of another.

In Donoghue v. Stevenson, the case involved a woman who became ill after drinking a ginger beer that contained a decomposed snail. Since she had no direct contractual relationship with the manufacturer, the ruling emphasized that manufacturers owe a duty of care to consumers, and the concept of foreseeability became crucial in determining that a duty of care existed.

This case marks a significant turn in the legal landscape as it formally recognized that individuals have a responsibility to act in ways that do not cause harm to others, which is a cornerstone of negligence claims. In subsequent cases, the principles introduced in Donoghue v. Stevenson were further refined, notably in Caparo Industries plc v. Dickman, which provided a three-part test for establishing a duty of care, but the foundational idea of reasonable foreseeability
