Year and a day rule
The Surgeon of CrowthorneThe Year and a day rule set a time limit linking a suspected act to a death for the purposes of murder law. In the account of the legal definition, the condition applied in England: death had to ensue within a year and a day after the act presumed to have caused it.
Legal Scope
The rule was not described as applying throughout Britain. The account expressly distinguishes England from Scotland, where this timing condition did not apply. It therefore marked a jurisdictional boundary within the legal treatment of murder, rather than a universal requirement.
Place in the Definition of Murder
The time limit appeared alongside other legal conditions: murder required the perpetrator to be of sound mind, and the death had to fall within the specified period after the presumed cause. The rule thus made the timing between an act and a resulting death relevant to whether the killing met the legal definition of murder.
