Whether the Eighth and Fourteenth Amendments permit the death penalty for a felony-murder accomplice who did not kill, attempt to kill, or intend that a killing occur or that lethal force be employed.
Holding
No. The death penalty is disproportionate and unconstitutional as applied to a defendant such as Enmund, whose personal culpability extended to participation in a robbery but not to killing, attempting to kill, or intending a killing.
Reasoning
The Eighth Amendment prohibits punishments that are excessive in relation to the defendant’s offense. Applying the proportionality approach used in Coker v. Georgia, the Court considered objective evidence of contemporary values—especially state legislation and actual sentencing practices—before exercising its own constitutional judgment.
Legislative enactments weighed against capital punishment for an accomplice like Enmund. Only a small minority of death-penalty jurisdictions authorized execution solely because a defendant participated in a robbery during which another participant killed. Many other jurisdictions required proof of an intentional, knowing, reckless, or otherwise culpable mental state regarding the homicide; restricted execution to actual killers; or treated minor accomplice participation as a mitigating factor.
Jury and execution data pointed in the same direction. Virtually all people executed for homicide had personally committed a homicidal assault or arranged for another to do so. The Court found no execution in the preceding quarter-century of a felony murderer who neither killed nor attempted to kill and who did not intend the victim’s death. Enmund was also essentially alone among Florida death-row inmates in having neither been the triggerman nor found to have intended a killing.
The constitutional inquiry must focus on Enmund’s own culpability, rather than automatically attributing the killers’ blameworthiness to him. Individualized capital sentencing requires attention to the particular offender’s character, actions, intentions, and moral guilt. Although robbery is grave and deserves serious punishment, Enmund’s proven conduct did not make him morally equivalent to the people who shot the Kerseys.
Neither principal justification for capital punishment supported Enmund’s execution. Death would have little deterrent value for someone who neither intended a killing nor contemplated the use of lethal force, because that person would not factor the prospect of a murder conviction and execution into the decision to participate in the felony. Robbery also results in homicide relatively rarely, further weakening any claim that capital punishment for every participant would deter robbery.
Retribution likewise could not justify the sentence. Intentional infliction of harm is more blameworthy than unintentional harm, and Enmund had not been found to have killed, tried to kill, intended to kill, or intended that lethal force be used. Executing him to avenge killings he neither committed nor intended would not tailor punishment to his personal responsibility and moral guilt. The Court therefore reversed the judgment upholding the death sentence and remanded for further proceedings.
