R v Dudley and Stephens (1884) 14 QBD 273

Following a shipwreck, Dudley, Stephens, another man and a cabin boy were stranded at sea with inadequate food and water. Dudley and Stephens killed the boy, who was weak and offered no threat to them, and the survivors consumed his body. They were later rescued. The defendants relied on the desperate circumstances, arguing that the killing was necessary for survival. The legal question was reserved for the court on the facts found by the jury, rather than arising as an ordinary appeal against a jury's general verdict.

Could necessity excuse the deliberate killing of an innocent person to preserve the defendants' lives in the circumstances of the shipwreck?

The court held that the killing was murder and that necessity did not excuse it. The defendants' extreme hunger and fear of death did not give them legal authority to select an innocent person to be killed for the others' benefit. The court also questioned how such a claimed entitlement could be limited or fairly determined.

The decision addressed the particular deliberate sacrifice of the cabin boy. It should not be expanded into a claim that every doctrine of necessity is excluded from every area of criminal or medical law. The later commutation of the sentence was an exercise of mercy, not a reversal of the legal conclusion that the defendants' conduct amounted to murder.

Necessity did not justify the deliberate killing of an innocent person to improve the defendants' prospects of survival on these facts. The case establishes a strict limit on invoking self-preservation to excuse murder, while distinct exceptional necessity questions must be analysed within their own authorities.

Dudley and Stephens is a leading illustration of the limits of necessity and of the separation between legal guilt and mercy in sentencing. It is particularly useful when a defendant claims that one person's death should be justified by the survival of others. An exam answer should identify the deliberate choice of an innocent victim and avoid equating the case with self-defence against an attacker or with every later medical necessity dispute.
