Introduction
R V. Dudley and Stephens (1884) is held as one of the seminal judgments in criminal law. It draws a definite line at the limits of necessity as a defense against murder. The case brings forth a legal and moral dilemma; is killing of an innocent person justifiable at the imminent threat of starvation?
The instance of two sailors killing an innocent vulnerable cabin boy to survive after a shipwreck brought before the Queen’s Bench Division demanded from the court to weigh between the human nature’s primal instinct of survival that in the situations such as the defendant’s tends to override all other senses, and the supreme sanctity of human life. The court’s rejection of necessity and self preservation as a defense upheld the unarguable value of human life, that under no circumstances can be subjected to the utilitarian calculations of “lesser evil.”
Today, R V. Dudley stands not only as a precedent but also an examination of the rule of law and human morality in situations where the conditions of civilised life have vanished.
Facts of the Case
On May 19, 1884 the “Mignonette”, a yacht departed from Southampton (Britain) heading towards Sydney (Australia). The crew was headed by Thomas “Tom” Dudley, the captain, while the rest of the crew included Edwin Stephens (mate), Edmund “Ned” Brooks (Seaman) and Richard Parker, a 17 year old cabin boy.
On 5th July 1884, the yacht was struck by a large wave and sank, while the crew escaped on a small dinghy with minimal food and no fresh water. Parker became ill from consuming seawater against advice and fell into a coma. By the 20th day stranded in the sea. With nothing to eat, Dudley proposed drawing lots to decide one person who would be sacrificed to save the rest. Brooks refused and no lots were drawn.
Soon, Dudley (with Stephens’ assent) killed Parker who was reportedly barely alive. The three men consumed the corpse for the next few days before being rescued by the German vessel “Montezuma.”
Upon returning to London, the men confessed to the ordeal, believing they were protected by the “Custom of Sea”[1] , which in essence stands for extreme acts, such as cannibalism being acceptable in circumstances outmatched, i.e., the crew being stuck in remote islands with no access to food or water. Such circumstances were not new and had been observed previously in cases such as that of the French vessel “Medusa” (1816), wherein 151 survivors floated for around two weeks before being rescued.
Legal Issues
Necessity as a Defence: Can necessity be invoked as a legitimate defence for an act of murder, and does it render such acts permissible under certain circumstances?
Arguments Presented
- Prosecution (The Crown)
- Sanctity of Life: The prosecution argued that killing was wilful murder, emphasizing that no legal excuse justified muder under any circumstances. The prosecution cited ‘Historia Placitorum Coronae’ or ‘The history of the Pleas of the Crown’ by Sir Matthew Hale, wherein the necessity cannot justify theft or murder.
- Lack of Provocation: The crown argued that Parker was the weakest in the crew, the youngest and ill, hence he posed no threat to the men. His killing was thus intentional as he was helpless, and not an act of self defense on the part of the crew.
- Definition of Murder: The act that led to Parker death fit the definition of muder in English Common law; “the unlawful killing of a human being under the Queen’s Peace committed with malice aforethought (intent to kill or cause grievous bodily harm).[2]
- Defense (Dudley & Stephens)
- Necessity: The defense argued that the men were in a state of extreme desperation. If they did not kill the victim, they would have all died.
- Utilitarian Calculation: The defense argued that Parker was allegedly in a coma (could not be verified due to the accused being the only witnesses). Furthermore, Parker had no dependents since he was young, while the other men had families. Hence, sacrificing one ill boy to save three healthy men was arguably “lesser of the two evils.”
- Custom of the Seas: The defense cited historical maritime instances of shipwrecked sailors resorting to murder and cannibalism to survive. They cited the infamous American case (United States V. Holmes, 18 U.S. (5 Wheat.) 412), wherein the sailors threw passengers off a crowded lifeboat to prevent it from sinking, arguing that situations such as this arise in the seas frequently and survivors should not be held liable for acting under duress.
Judgement
The court, in a unanimous decision of the 5-judge bench, found the defendants guilty of murder and charged them with death, which was later commuted to six months imprisonment by the crown. In the judgment declared by Lord Coleridge CJ, the court used the following reasoning[3]:
- Rejection of Necessity: The court established that necessity cannot justify murder in the absence of any threat by the victim. It analysed various authorities including treatises of jurists such as Sir Matthew Hale (The history of the Pleas of the Crown), Sir Michael Foster (Discourse on Homicide), and Lord Bacon (Commentary on Necessity), to determine that necessity has been used as a defense in cases of self-defense wherein the victim posed a reasonable threat to the assailant. Herein, the victim was already vulnerable, and hence did not pose a threat to the men. Hence, his death was an act of aggression for self preservation, and not an act of defense. The court excluded unlawful killing of innocent persons to preserve one’s own life under extreme circumstances as self defense. The court refused to accept the defense’s argument of “choice of evils” when innocent lives were at stake.
- Impossibility of Objective Determination: The court highlighted the risks of permitting such a defence. There is no objective standard by which the court can measure the value of lives in comparison to one another. There exists no standard for determining who “deserves” to live under the extreme circumstances. The court held that validating the defendants’ choice would set a precedent that would allow the strong to prey on the weak. It would cause the value of human life to be dependent on physical or social superiority. The court also stressed that it is one’s duty to sacrifice one’s own life to save another’s. While the instinct of survival is powerful, it is not a legal absolute.
Critical Analysis
The decision of the court to reject necessity as a defense of murder in cases of lack of reasonable threat removed any ambiguity in distinction between self-preservation and self defense. The ruling prevented any future cases on defendants claiming necessity as a defense for heinous crimes committed under the guise of survival. The ruling also intervened into the prevailing maritime customs by holding the survivors accountable for crimes such as muder and cannibalism. This ensured protection of the weaker or vulnerable members of the group. Especially since in all previous incidents it was only healthy, rich, white men who survived by consuming the downtrodden. The court acknowledged that the duty of law is to uphold a moral standard and not accommodate instances of human weakness. Ultimately the court protected the moral sanctity of the value of life by upholding that human life is priceless and cannot be calculated or traded.
However, following the ruling and even in contemporary times, many argue that courts cannot comprehend the dire situations of starvation that arose under such circumstances. To label men acting under duress as “murders” seemed disproportionate to the people. The law demands an act of self sacrifice that is unnatural to most humans.
Conclusion
The judgment of the court in R V. Dudley and Stephens stand at the threshold of the debate between Utilitarianism and Deontology. While the utilitarian perspective would argue that the muder of Richard Parker was moral, since it saved the lives of 3 other men, and hence was the greatest common good in the given situation. On the other hand, the Deontologist school of thought would argue that the act of killing is inherently wrong as the life of a human being cannot be reduced to a means to an end. The case is often cited even beyond the realms of law, extending into various ideologies of morality and philosophy. The verdict demands of us to do better than our basal instinct of survival, and aspire to rise to a moral high ground.
In contemporary times, the case has raised questions akin to the trolley problem. It forces us to think about what we would do if we were on that boat?
