Juveniles no longer given death penalty

For the Majority

This case requires us to address, for the second time in a decade and a half, whether it is permissible under the Eighth and Fourteenth Amendments to the Constitution of the United States to execute a juvenile offender who was older than 15 but younger than 18 when he committed a capital crime. In Stanford v. Kentucky, 492 U. S. 361 (1989), a divided Court rejected the proposition that the Constitution bars capital punishment for juvenile offenders in this age group. We reconsider the question.

[...]

Three general differences between juveniles under 18 and adults demonstrate that juvenile offenders cannot with reliability be classified among the worst offenders. First, as any parent knows and as the scientific and sociological studies respondent and his amici cite tend to confirm, "[a] lack of maturity and an underdeveloped sense of responsibility are found in youth more often than in adults and are more understandable among the young. These qualities often result in impetuous and ill-considered actions and decisions." Johnson, supra, at 367; see also Eddings, supra, at 115-116 ("Even the normal 16-year-old customarily lacks the maturity of an adult").

The second area of difference is that juveniles are more vulnerable or susceptible to negative influences and outside pressures, including peer pressure. Eddings, supra, at 115 ("[Y]outh is more than a chronological fact. It is a time and condition of life when a person may be most susceptible to influence and to psychological damage"). This is explained in part by the prevailing circumstance that juveniles have less control, or less experience with control, over their own environment. See Steinberg & Scott, Less Guilty by Reason of Adolescence: Developmental Immaturity, Diminished Responsibility, and the Juvenile Death Penalty, 58 Am. Psychologist 1009, 1014 (2003) (hereinafter Steinberg & Scott) ("[A]s legal minors, [juveniles] lack the freedom that adults have to extricate themselves from a criminogenic setting").

The third broad difference is that the character of a juvenile is not as well formed as that of an adult. The personality traits of juveniles are more transitory, less fixed. See generally E. Erikson, Identity: Youth and Crisis (1968). These differences render suspect any conclusion that a juvenile falls among the worst offenders. The susceptibility of juveniles to immature and irresponsible behavior means "their irresponsible conduct is not as morally reprehensible as that of an adult." Thompson, supra, at 835 (plurality opinion). Their own vulnerability and comparative lack of control over their immediate surroundings mean juveniles have a greater claim than adults to be forgiven for failing to escape negative influences in their whole environment. See Stanford, 492 U. S., at 395 (Brennan, J., dissenting). The reality that juveniles still struggle to define their identity means it is less supportable to conclude that even a heinous crime committed by a juvenile is evidence of irretrievably depraved character. From a moral standpoint it would be misguided to equate the failings of a minor with those of an adult, for a greater possibility exists that a minor's character deficiencies will be reformed.

[...]

In concluding that neither retribution nor deterrence provides adequate justification for imposing the death penalty on juvenile offenders, we cannot deny or overlook the brutal crimes too many juvenile offenders have committed. See Brief for Alabama et al. as Amici Curiae. Certainly it can be argued, although we by no means concede the point, that a rare case might arise in which a juvenile offender has sufficient psychological maturity, and at the same time demonstrates sufficient depravity, to merit a sentence of death.

Indeed, this possibility is the linchpin of one contention pressed by petitioner and his amici. They assert that even assuming the truth of the observations we have made about juveniles' diminished culpability in general, jurors nonetheless should be allowed to consider mitigating arguments related to youth on a case-by-case basis, and in some cases to impose the death penalty if justified.

A central feature of death penalty sentencing is a particular assessment of the circumstances of the crime and the characteristics of the offender. The system is designed to consider both aggravating and mitigating circumstances, including youth, in every case.

Given this Court's own insistence on individualized consideration, petitioner maintains that it is both arbitrary and unnecessary to adopt a categorical rule barring imposition of the death penalty on any offender under 18 years of age.

The Eighth and Fourteenth Amendments forbid imposition of the death penalty on offenders who were under the age of 18 when their crimes were committed. The judgment of the Missouri Supreme Court setting aside the sentence of death imposed upon Christopher Simmons is affirmed.

It is so ordered.
