Applying the Categorical Bars
The categorical decisions each took one kind of sentence away from one group of defendants or one group of crimes, and a fact pattern rarely announces which of them it is testing. The decisions fall into two subsets, one that looks at the nature of the offense and one that looks at the characteristics of the offender.1 Graham v. Florida then used the same method on a term of imprisonment, which the Court had not done before.2 Because each bar attaches to a particular sentence, applying them means fixing the sentence first and testing the facts against the bars in a set order, since a rule that governs death says nothing about a prison term.
The starting point is that death is not itself forbidden. Gregg v. Georgia held that the death penalty for murder is not in itself cruel and unusual, although the defendant's character must be considered in deciding whether to impose it.3 The Court has since described capital punishment as neither invariably cruel and unusual nor always disproportionate to the crime for which it is imposed.4 Individual Justices, among them Brennan, Marshall, and Blackmun, would have held it unconstitutional in every case and dissented from affirmances on that ground, but that position has never been the Court's holding.5 Every bar below is therefore an exit from a baseline of permissibility. A defendant who fits no exit may be sentenced to death, so the analysis looks for a bar and does not presume the sentence invalid.
Steps two and three draw on different reasoning, and keeping them apart is the skill the next two parts practice.
Sorting Offender From Offense
The offender-based and offense-based bars answer different questions, which is why one set of facts can trigger one bar, both, or neither. The offender-based bars rest on a mismatch between the diminished culpability of a class of offenders and the severity of the penalty.9 The class characteristic carries the analysis, so a deliberate murder by someone who was under 18 when it was committed still cannot be punished by death.10 The offense-based bars ask whether death is disproportionate to a kind of crime, whoever commits it. In Coker v. Georgia the Court said plainly that rape is highly reprehensible, and it still held death disproportionate for the rape of an adult woman.11 Seriousness short of a taking of life does not change that answer, and the offender's own traits play no part in it.
Because the two lines are independent, a single fact pattern can fall inside both, and a complete answer names each. Stopping at the first bar that fits hides which fact is doing the work, and a changed fact can switch off one bar while leaving the other in place.
The offender-based point comes from Roper v. Simmons, which measures age at the time of the capital crime.12 The offense-based point comes from Coker, which bars death for the rape of an adult woman who does not die.13 Each bar can also work alone. Kennedy v. Louisiana bars death for the rape of a child where the crime neither was intended to result in death nor did, and the offender needs no protected characteristic to invoke it.14 The offender-based bar can likewise decide a case in which the offense-based bar is unavailable.
That result follows from Atkins v. Virginia, which makes intellectually disabled defendants categorically ineligible for capital punishment.15 The remaining branch of the sequence concerns a sentence other than death. In Graham, a sixteen-year-old took part in an attempted restaurant robbery in which an accomplice struck the manager with a metal bar, and the manager survived with an injury that required stitches.16 Life without parole was barred because the offender was a juvenile and the offense was not a homicide.17 The sentence was not death, so none of the capital bars was in play, which is why the sequence fixes the sentence before anything else. The bar was drawn to mirror the capital rule against punishing nonhomicide crimes against individuals.18 Flip the homicide fact and a juvenile murderer falls outside this flat bar, with Miller v. Alabama governing any scheme that mandates life without parole for juveniles.19
Where No Bar Applies
When no step produces a bar, the problem leaves the categorical analysis without leaving the Eighth Amendment. Death remains available for an adult who is not intellectually disabled and who commits a deliberate murder, but only through a scheme that lets the sentencer weigh mitigating evidence. In McCleskey v. Kemp the Court summarized that a sentencer cannot be precluded from considering, as a mitigating factor, any aspect of the defendant's character or record or any circumstance of the offense offered as a basis for a sentence less than death.20 A mandatory death sentence for first-degree murder fell in Woodson v. North Carolina for the same reason, because it allowed no individualized consideration.21
The bars also stop where their own terms stop. Mental illness is not intellectual disability, and the offender-based bar covers only the latter.22 In Dickerson v. State a Mississippi court declined to extend Atkins to a death-sentenced murder defendant who was mentally ill but not intellectually disabled.23 The condition still matters, because defendants routinely offer evidence of mental disability at the penalty phase to persuade jurors against death.24 A separate rule protects prisoners who are insane, but it has its own terms and sits outside this checklist.
That culpability question comes from a line of cases separate from the categorical bars. Death is valid for a felony-murder accomplice who participated in a major way and acted with reckless disregard for the value of human life. Enmund v. Florida barred death for a felony-murder defendant absent a showing of a sufficiently culpable mental state.25 The accomplice therefore needs a different analysis from the nonhomicide-offense bar, even though both involve a defendant who did not personally kill.
Sentences other than death and juvenile life without parole fall into the remaining space. The Graham bar reaches only juveniles, so an adult challenging a long prison term goes through case-by-case review, which begins by comparing the gravity of the offense with the severity of the sentence. Only in the rare case where that comparison suggests gross disproportionality does the court compare the sentence with those given in the same jurisdiction and elsewhere.26 The route has rarely succeeded: the controlling opinion in Harmelin v. Michigan upheld life without parole for possessing more than 650 grams of cocaine,27 while a life-without-parole sentence for a seventh nonviolent felony, passing a worthless check, was struck down in Solem v. Helm.28 Relief is available, if at all, only in extreme cases, and long sentences for adults, even life sentences, have so far withstood attack.29 The general tests remain available at this stage: a punishment is excessive if it makes no measurable contribution to acceptable goals of punishment or is grossly out of proportion to the severity of the crime.30
This reading does not settle every juvenile-sentencing question, and each bar reaches only what its own terms cover. The age line is 18 at the time of the crime, the intellectual-disability bar needs intellectual disability, and the offense-based bar is stated for nonhomicide crimes against individuals.31
