Donoghue v Stevenson is decided, ultimately establishing the foundation for negligence in common law jurisdictions worldwide.

Donoghue v Stevenson [1932] AC 562 was a landmark court decision in Scots delict law and English tort law by the House of Lords. It laid the foundation of the modern law of negligence in common law jurisdictions worldwide, as well as in Scotland, establishing general principles of the duty of care.

Negligence is a failure to exercise appropriate care expected to be exercised in similar circumstances.

Common law is the body of law primarily developed through judicial decisions rather than statutes. Although common law may incorporate certain statutes, it is largely based on precedent—judicial rulings made in previous similar cases. The presiding judge determines which precedents to apply in deciding each new case.
