R v White [1910] 2 KB 124 is a leading decision of the Court of Appeal on the principles of causation and criminal attempt in English criminal law. The case is particularly significant for establishing the “but for” test of causation and for clarifying when an act amounts to an attempt to commit murder, even where the completed act would not have been sufficient to cause death.
The decision in R v White continues to be cited as authority on both factual causation and the law relating to attempt. The case illustrates the distinction between liability for murder and liability for attempted murder, and it demonstrates how intention and conduct are assessed by the court.
Facts of R v White Case
In R v White, the defendant purchased poison shortly before his mother was found dead. She was discovered next to a glass of lemonade which had been poisoned. The evidence showed that the defendant had placed poison into the drink.
However, the medical evidence was clear. The deceased had not died from poisoning. There was no evidence of poison in her body. Instead, it appeared that she had died coincidentally from a heart attack. The heart attack was entirely unrelated to the poison placed in the lemonade.
It was also established that there was not enough poison in the glass to kill an adult woman. In other words, even if the woman had not suffered a heart attack, the quantity of poison in the drink would not have been sufficient to cause her death.
Despite this, a jury convicted the defendant of attempted murder.
Legal Issues
The appeal in R v White raised two principal issues.
First, whether there was sufficient evidence for the jury to conclude that the defendant intended to kill his mother. Since intention is a crucial element of attempted murder, the court had to consider whether the available evidence supported such a finding.
Secondly, whether there could be an attempt to commit murder where the completed act was insufficient to bring about the ultimate crime. In particular, the question was whether putting an inadequate amount of poison in a drink could amount to an attempt to kill.
A related issue concerned causation. Since the deceased had died from a heart attack and not from poisoning, the court had to determine whether the defendant could be held responsible for her death.
Decision of the Court of Appeal
The Court of Appeal upheld the defendant’s conviction for attempted murder in R v White.
On the question of intention, the court found that there was enough evidence for the jury to conclude that the defendant had placed the poison in the glass with intent to kill. The act of purchasing poison shortly before the death, combined with the poisoned drink, was capable of supporting that conclusion.
On the question of attempt, the Court of Appeal rejected the argument that the act was insufficient because the poison was not capable of killing. The defendant had argued that because there was not enough poison in the glass to cause death, the act could not amount to an attempt.
It was suggested that for the poison to be deadly, multiple doses would have been required, and it was uncertain whether those further acts would ever have been carried out.
The court dismissed this argument. Bray J stated:
“The completion or attempted completion of one of a series of acts intended by a man to result in killing is an attempt to murder even although this completed act would not, unless followed by the other acts, result in killing. It might be the beginning of the attempt, but would none the less be an attempt.”
The court further observed that there was evidence that the defendant believed he had put enough poison in the glass to kill the woman. On that basis, the jury could properly conclude that there had been an attempt to commit murder.
The conviction for attempted murder was therefore upheld.
The “But For” Test of Causation
Although the defendant was convicted of attempted murder, he was not convicted of murder. This distinction in R v White is of major importance in the law of causation.
The case demonstrates that a person does not cause a result, such as death, unless it can be shown that “but for” the defendant’s act, the result would not have occurred. This principle became known as the “but for” test of factual causation.
In R v White, even if the defendant had not placed poison in the drink, the woman would still have died because she suffered a heart attack. Her death was not caused by the poison. Since the poison did not bring about her death, the defendant could not be held liable for murder.
The case therefore illustrates the requirement of factual causation in criminal law. If the prohibited consequence would have occurred in any event, the defendant’s act cannot be said to have caused it.
Attempt and Insufficient Means
One of the most important aspects of R v White concerns the law of attempt.
The defendant argued that the act of putting poison in the glass could not amount to an attempt because it was insufficient to cause death. Since the quantity of poison was not enough to kill, and since further acts would have been required to achieve that result, it was contended that the conduct fell short of an attempt.
The Court of Appeal rejected this reasoning. The court made it clear that an attempt can exist even where the act done would not, by itself, have produced the intended result.
Bray J’s statement makes this principle clear. The beginning or completion of one act in a planned series of acts intended to result in killing may constitute an attempt, even if that single act would not cause death unless followed by further steps.
Furthermore, there was evidence that the defendant thought he had used enough poison to kill. This meant that, from his perspective, he believed the act was capable of bringing about death. That belief supported the conclusion that there was an attempt.
Thus, R v White establishes that the law does not require the act to be objectively capable of causing death at that moment. It is sufficient that the defendant has begun carrying out acts intended to bring about that result.
Appeal Against Sentence
The case also involved an appeal against the defendant’s sentence. However, the sentencing principles applied in that appeal are no longer relevant to modern law. The enduring importance of the case lies instead in its treatment of causation and attempt.
Conclusion
R v White remains a foundational authority in English criminal law. It demonstrates that liability for murder requires proof of factual causation, established through the “but for” test. Since the victim would have died from a heart attack regardless of the poison, the defendant in R v White could not be convicted of murder.
At the same time, the case confirms that an attempt can exist even where the completed act was insufficient to cause the intended harm. By placing poison in the drink with intent to kill, the defendant had begun carrying out his plan. That conduct was sufficient to amount to attempted murder.
The principles established in R v White continue to shape the law on causation and attempt, and the case remains a central authority in the study of criminal liability.
