The rule that gave homicide a deadline.
For seven centuries, a death that arrived more than a year and a day after the blow could not be murder. Medicine made the rule obsolete, and in 2001 the Supreme Court let a state erase it.
A killing on the clock
In May 1994, a man named Wilbert Rogers stabbed James Bowdery in the heart with a butcher knife. Bowdery survived the wound, but a complication set in, he slipped into a coma, and he died about fifteen months later. Rogers was convicted of second degree murder. On appeal he made an argument that would have sounded ordinary to a lawyer of the sixteenth century and strange to almost anyone today: because his victim had lived more than a year and a day after the stabbing, the law could not treat the death as a murder at all.
He was invoking one of the oldest rules in the criminal law, the year and a day rule. For most of the history of the common law, no one could be convicted of homicide unless the victim died within a year and a day of the act said to have killed him. Live past that window, and the death was, in the eyes of the law, no longer caused by the blow. The clock, not the coroner, decided.
Where the deadline came from
The rule is usually traced to the Statute of Gloucester in 1278. It did not start life as a rule about murder at all. It began as a limitation period, a deadline for bringing the medieval "appeal of death," a private prosecution a victim's kin could pursue. Over the centuries the deadline migrated from procedure into substance, until it hardened into a statement about causation itself: a death that came too late simply was not caused, as a matter of law, by the earlier wound.
By the seventeenth century the doctrine was settled enough for Sir Edward Coke to write it into his Institutes, describing murder as a killing where the party hurt dies of the wound "within a year and a day after the same." William Blackstone repeated it in his Commentaries a century later. The reason judges gave was practical, not philosophical. Medieval and early modern medicine had no reliable way to say whether a death months or years after an injury was really the injury's doing, or whether disease, another hurt, or simple bad luck had intervened. A year and a day was a rough, workable proxy for proof that early courts otherwise could not get.
Why it stopped making sense
What was a sensible shortcut in 1300 became a strange one by the modern era. Forensic medicine grew able to connect an injury to a death across long spans of time, so the evidentiary problem the rule was built to solve largely disappeared. At the same time, life support created the opposite problem. A victim could be kept alive on machines well past a year and a day, so that the more grievous the wound and the longer the fight to survive it, the more likely the attacker was to escape a homicide charge on a technicality of the calendar. A rule invented to keep the state from overreaching had become, in some cases, a shield for the person who struck the blow.
A medieval deadline
It traces to the Statute of Gloucester in 1278, where it began as a time limit on how long after an act a killing could be pursued.
A stand-in for proof
With no way to trace a death to an old wound, a year and a day served as rough proof that the injury, and not something else, was the cause.
Overtaken by medicine
Forensic science can now link an injury to a death years later, and life support can push death past any fixed window.
Mostly gone now
England abolished it in 1996. Most US jurisdictions have dropped or modified it; California allows three years and a day.
What the Supreme Court did with it
Which brings the story back to Wilbert Rogers. By the time of his appeal, Tennessee's murder statute said nothing about a year and a day, but the old common-law rule had never formally been repealed there. The Tennessee Supreme Court decided the moment had come to abolish it, and it upheld Rogers's conviction. Rogers took the case to Washington with a constitutional objection: a court had, in effect, expanded criminal liability after the fact and applied the change to him, the very kind of retroactive move the Constitution's Ex Post Facto Clause forbids.
The Ex Post Facto Clause is a restraint on legislatures. Courts change the common law all the time. The question was whether a judicial change can be so unfair that due process forbids applying it to past conduct.
In Rogers v. Tennessee, decided in May 2001, a divided Court answered no, not here. Writing for a five-Justice majority, Justice Sandra Day O'Connor explained that the Ex Post Facto Clause by its terms binds legislatures, not judges, so a court's decision to discard an old doctrine is measured instead by the due-process principle of fair warning. A judicial change to the criminal law offends that principle, the Court held, only when it is "unexpected and indefensible by reference to the law which had been expressed" before the defendant acted. Abolishing a rule that was widely seen as an obsolete relic, and that Tennessee courts had already questioned, was neither unexpected nor indefensible. The conviction stood.
Four Justices disagreed. In a dissent joined by Justices Stevens and Thomas, and in part by Justice Breyer, Justice Antonin Scalia argued that letting a court retroactively enlarge criminal liability did the same damage to fair warning that the Ex Post Facto Clause was written to prevent, whatever branch of government happened to be doing it. The split was less about the year and a day rule, which few defended on the merits, than about who may change a criminal rule, and when the change may reach conduct that came before it.
Where the rule stands now
The deadline is now mostly a matter of legal history. In England and Northern Ireland, Parliament ended it directly: the Law Reform (Year and a Day Rule) Act 1996 abolished the conclusive presumption for all purposes, while adding a safeguard that the Attorney General must consent to a prosecution when death comes more than three years after the act, or when the defendant has already been convicted of a connected offense. Across the United States, the rule has fallen jurisdiction by jurisdiction, some by statute and some by court decision, with the District of Columbia rejecting it in the 1980s and states such as Wisconsin following later.
A few places kept a version of it rather than scrap it outright. California, for one, did not abolish the idea so much as stretch and soften it. Under Penal Code section 194, if a death occurs beyond three years and a day after the act, there is a rebuttable presumption that the killing was not criminal, a presumption prosecutors can overcome with proof, rather than an absolute bar. The old fixed deadline became a starting assumption that evidence can move.
The rule survived for seven hundred years because it answered a real question the courts of its day could not: did this wound cause this death?
It faded once medicine could answer that question directly, and once judges decided that causation should be proved, not presumed from a calendar.
