Court: House of Lords (UK)
Key Legal Principle: Presumption of Innocence.
The Burden of Proof: The “Golden Thread” principle.
Reginald Woolmington, a young man, was charged with the murder of his wife.
He admitted to the shooting but claimed it was a tragic accident. He testified that he only intended to frighten her into returning home by threatening to shoot himself, but the gun discharged accidentally.
The trial judge incorrectly directed the jury that once the killing was proven, the burden of proof shifted to the defendant to show it was an accident.
Does the defendant have to prove his innocence (accident), or must the Prosecution prove guilt beyond reasonable doubt, even when a death has occurred?
The House of Lords quashed the conviction.
Lord Sankey delivered his monumental “Golden Thread” speech, stating that the prosecution always bears the burden of proving the prisoner’s guilt.
“Throughout the web of the English Criminal Law one golden thread is always to be seen, that it is the duty of the prosecution to prove the prisoner’s guilt… No matter what the charge or where the trial, the principle that the prosecution must prove the guilt of the prisoner is part of the common law of England and no attempt to whittle it down can be entertained.”
First of all, the Woolmington case changed English law forever.
Historically, courts often forced defendants to prove their innocence in certain situations.
However, Lord Sankey rejected this approach entirely.
Consequently, the burden of proof now stays with the prosecution from start to finish.
Moreover, this “Golden Thread” ensures that no judge can undermine the presumption of innocence.
In short, if the prosecution fails to prove guilt, the defendant must go free.
This case is the cornerstone of our Academy. It establishes that the defendant is not required to prove anything. If the prosecution’s case contains “fog” or unreliable evidence, the benefit of the doubt belongs to the accused. In Dubio Pro Reo.
