In July 1884, the English yacht Mignonette sank in a storm thousands of miles from land, leaving four crew members stranded in a tiny lifeboat: Tom Dudley, Edwin Stephens, Edmund Brooks, and 17-year-old cabin boy Richard Parker. With virtually no provisions, the men endured weeks of starvation and severe dehydration in the open ocean. By the twentieth day, Parker fell unconscious after drinking seawater.
Believing the boy was near death anyway, Captain Dudley and Stephens decided to sacrifice Parker to feed themselves and Brooks. Four days later, a passing German vessel rescued the three survivors. Upon returning to England, Dudley and Stephens openly admitted to killing Parker, expecting their actions to be excused under the long-standing custom of the sea, an unwritten maritime tradition where desperate sailors resorted to cannibalism for survival.
However, the British legal establishment chose to make a definitive stand against this practice. The resulting trial, R v Dudley and Stephens, reached the High Court of Justice. Chief Justice Lord Coleridge rejected the argument of necessity, ruling that no human being has the right to decide whose life is more valuable than another's.
The court declared that self-preservation is not an absolute duty and that necessity cannot justify murder. Dudley and Stephens were sentenced to death, though their sentences were later commuted by the Crown to six months in prison. This precedent permanently closed the legal loophole for necessity in homicide cases across common law jurisdictions.
