The Common-Law Time Limit

The Common-Law Time Limit

The year-and-a-day rule makes elapsed time a condition of homicide liability. A prosecutor charging a killing at common law had to show that the victim died within one year and one day of the injury or wound the defendant inflicted.¹ Two events mark the boundaries of that window: the injury starts the clock, and the death stops it. When the death falls inside the window, the time limit is satisfied and the usual questions of cause in fact and proximate cause decide the outcome. When the death falls outside, the homicide charge fails at the threshold, even if the defendant's conduct plainly satisfied but-for causation.²

The medical testimony in the second version is as strong as in the first, so the only variable that moved the result is elapsed time. That is where students go wrong, because the clock does not ask how certain the causal link is. The causation inquiry measures whether the defendant's act produced the death. The time limit measures only the gap between injury and death, and it can defeat a charge that the causation evidence would otherwise support.

The shape of the rule follows from two separate concerns. A fixed cutoff answers a problem of proof: the longer a victim survives, the more illnesses, treatments, and other events accumulate between the wound and the death, and the harder it becomes to say that the wound rather than something later produced the result. A bright line spares courts from litigating that doubt case by case. The outer limit also answers a problem of exposure. Homicide carries the heaviest penalties and the greatest stigma in the criminal law, and without a boundary a person who injured another would remain open to a murder or manslaughter charge for as long as the victim happened to survive. The next two sections take up the working pieces of the rule in turn, first what the bar does when the period has run and then how the period is counted. The fuller account of why the common-law courts chose this device comes after them.

The Bar on Homicide

The year-and-a-day rule operates as a gate on the homicide charge itself. When the victim dies after the period has run, the prosecution cannot charge homicide, and it does not matter that the defendant's conduct plainly satisfied but-for causation.⁴ The bar is categorical because the rule treats elapsed time as a legal limit rather than as a fact for the jury to weigh. A limit left to the jury could come out differently on the same interval from one trial to the next, and it would invite the prosecution to fill a long gap with dramatic medical testimony about events far in the past. A fixed legal limit removes both problems, since a court that finds the interval too long never reaches the causation evidence at all.

The clock has two fixed endpoints: the injury starts it and the death stops it. A Massachusetts court stated the point in Commonwealth v. Macloon by describing criminal homicide as the unlawful taking of a life in such a way that the victim dies within a year and a day from the time of the mortal wound, with the crime being murder if malice is present and manslaughter if it is absent.⁵ That description marks the reach of the bar. It speaks of homicide, which covers both murder and manslaughter, so a death outside the period forecloses either charge. The same opinion adds that a personal injury, however grave, that does not end in death is neither crime.⁶ Before the death there is therefore no homicide to measure, and the rule limits how far the death may trail behind the injury.

Because the rule reaches homicide and nothing else, the defendant's other wrongdoing remains chargeable. A defendant whose victim dies too late for a murder prosecution may still face a lesser offense such as assault with intent to kill.⁷ The reason follows from what each offense requires. An assault-type offense is complete when the defendant acts with the required intent and inflicts the injury, so its elements never call for a death, and the delay between injury and death takes nothing away from it. Homicide differs because the death is an element the prosecution must prove, and the rule restricts how late that element may arrive. The rule is therefore a limit on what the State may charge. The defendant's act remains wrongful, and every offense that does not depend on the death stays available, so only the homicide label and the penalties that attach to it are foreclosed.

The decided cases show the same pattern with real dates. In Rogers v. Tennessee the defendant stabbed James Bowdery with a butcher knife on May 6, 1994, and one wound penetrated the heart; Bowdery survived the surgery but lost oxygen to the brain, remained in a coma, and died on August 7, 1995, from a kidney infection, a common complication in comatose patients.⁸ The county medical examiner's undisputed testimony traced the death to the stab wound, so but-for causation was settled, yet about fifteen months separated the injury from the death.⁹ Under the common-law rule as the Court described it, no defendant could be convicted of murder unless the victim died by the defendant's act within a year and a day, so those facts fall outside the period and the homicide charge would have been barred.¹⁰ The conviction stood only because Tennessee's highest court abolished the rule and applied its decision to the defendant, a step taken up later in this chapter.¹¹

A modern Alabama case, Ex parte Key, presents the same timing problem alongside a charge that does not depend on the death. A car struck Brian Rollo on March 28, 1997, and he died on October 2, 1998, about eighteen months later, of complications from his injuries.¹² The grand jury indicted Ralph Lynn Key for murder and for leaving the scene of an accident in which someone was injured, and Key moved to dismiss the murder indictment on the strength of the year-and-a-day rule.¹³ The Alabama Supreme Court reversed his manslaughter conviction and remanded his leaving-the-scene conviction with instructions.¹⁴ That offense is defined by an injury to someone rather than by a death, which is why it could be treated as a count separate from the homicide counts.

Placing the two sides together isolates the variable that matters. If D shoots V on January 1, 2018, and V dies on January 1, 2019, the death falls within the period, the rule does not bar the homicide prosecution, and the State must still prove causation in the ordinary way.¹⁵ Keep the shooting, the wound, and the medical cause identical but let V linger past the period, as Bowdery lingered for fifteen months in Rogers, and the homicide charge disappears while the causation evidence stays exactly as strong. The only fact that moved the result is when the victim died.

The common mistake is to let strong causation evidence stand in for the time limit. No amount of causation proof reopens a homicide charge once the period has run, because cause in fact and proximate cause ask whether the defendant's act produced the death, and the time limit asks only how much time separated the injury from the death. In Rogers the medical link was undisputed, and the interval alone decided whether homicide could be charged under the common-law rule. On an exam stem with a late death, the first question is therefore the elapsed time, and the second is which charges survive if that time is too long.

Counting the Period

The formula of a year and a day invites a misreading, because it sounds like a full year with a bonus day tacked on at the end. The extra day was a counting convention. Under the older method of reckoning time, both the first day and the last day of a span were counted, so a year running from January 1 was thought to end on December 31, and a day was added so that the span would run through the following January 1 and make a complete year.¹⁷ Criminal law gave the habit a further push, since a period measured from an act was then taken to begin on the very day the act was done, and the added day ensured that the 365th day after the injury was counted.¹⁸ The same phrase served as a time-limit formula in other common-law settings, such as claims to wreckage, so it was never peculiar to homicide.¹⁹

The modern method of counting excludes the first day and includes the last, so a year from January 1 ends on the next January 1, which is the very endpoint the old method reached by adding a day.²⁰ The two methods therefore converge on one result: the period is a single full year, measured from the date of the injury. A bright-line rule needs a fixed way of measuring the line, because a cutoff that different judges counted differently would bring back the case-by-case argument the rule exists to avoid. With the convention settled, the only open question in a given case is when the victim died, and the length of the span is never in dispute.

Two dates decide the count. The common-law rule required that the victim die within the period running from the injury, so the date of the injury opens the count and the date of death is tested against its end.²¹ The standard illustration fixes the boundary exactly. If D shoots V on January 1, 2018, and V dies on January 1, 2019, the death falls on the last day of the period, so a criminal homicide has occurred and the rule does not bar a murder prosecution.²² If V instead dies on January 2, 2019, or on any later date, the period has run and a murder prosecution is barred, although D may still be charged with a lesser offense such as assault with intent to kill.²³ Holding the wound and its medical cause constant, the only fact that changed between the two outcomes is a single day.

The trap lies in the phrase itself. A reader who takes the extra day literally adds it after the anniversary and places January 2, 2019 inside the period. The convention forecloses that reading: the anniversary of the injury is the last day inside the period, and the next day is outside it. Because the bar is categorical, as the preceding section showed, the one-day difference decides the case. A death on the anniversary leaves the State to prove causation in the ordinary way, while a death the following day ends the homicide prosecution however strong the medical evidence is.
