The description of the murder in the following case is graphic and potentially upsetting.

U.S. Supreme Court

Roper v. Simmons, 543 U.S. 551 (2005)

 

Justice Kennedy delivered the opinion of the Court.

   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.

I

   At the age of 17, when he was still a junior in high school, Christopher Simmons, the respondent here, committed murder. About nine months later, after he had turned 18, he was tried and sentenced to death. There is little doubt that Simmons was the instigator of the crime. Before its commission Simmons said he wanted to murder someone. In chilling, callous terms he talked about his plan, discussing it for the most part with two friends, Charles Benjamin and John Tessmer, then aged 15 and 16 respectively. Simmons proposed to commit burglary and murder by breaking and entering, tying up a victim, and throwing the victim off a bridge. Simmons assured his friends they could “get away with it” because they were minors.

   The three met at about 2 a.m. on the night of the murder, but Tessmer left before the other two set out. (The State later charged Tessmer with conspiracy, but dropped the charge in exchange for his testimony against Simmons.) Simmons and Benjamin entered the home of the victim, Shirley Crook, after reaching through an open window and unlocking the back door. Simmons turned on a hallway light. Awakened, Mrs. Crook called out, “Who’s there?” In response Simmons entered Mrs. Crook’s bedroom, where he recognized her from a previous car accident involving them both. Simmons later admitted this confirmed his resolve to murder her.

   Using duct tape to cover her eyes and mouth and bind her hands, the two perpetrators put Mrs. Crook in her minivan and drove to a state park. They reinforced the bindings, covered her head with a towel, and walked her to a railroad trestle spanning the Meramec River. There they tied her hands and feet together with electrical wire, wrapped her whole face in duct tape and threw her from the bridge, drowning her in the waters below.

   By the afternoon of September 9, Steven Crook had returned home from an overnight trip, found his bedroom in disarray, and reported his wife missing. On the same afternoon fishermen recovered the victim’s body from the river. Simmons, meanwhile, was bragging about the killing, telling friends he had killed a woman “because the bitch seen my face.”

   The next day, after receiving information of Simmons’ involvement, police arrested him at his high school and took him to the police station in Fenton, Missouri. They read him his Miranda  rights. Simmons waived his right to an attorney and agreed to answer questions. After less than two hours of interrogation, Simmons confessed to the murder and agreed to perform a videotaped reenactment at the crime scene.

   The State charged Simmons with burglary, kidnaping, stealing, and murder in the first degree. As Simmons was 17 at the time of the crime, he was outside the criminal jurisdiction of Missouri’s juvenile court system. See Mo. Rev. Stat. §§211.021 (2000) and 211.031 (Supp. 2003). He was tried as an adult. At trial the State introduced Simmons’ confession and the videotaped reenactment of the crime, along with testimony that Simmons discussed the crime in advance and bragged about it later. The defense called no witnesses in the guilt phase. The jury having returned a verdict of murder, the trial proceeded to the penalty phase.

   The State sought the death penalty. As aggravating factors, the State submitted that the murder was committed for the purpose of receiving money; was committed for the purpose of avoiding, interfering with, or preventing lawful arrest of the defendant; and involved depravity of mind and was outrageously and wantonly vile, horrible, and inhuman. The State called Shirley Crook’s husband, daughter, and two sisters, who presented moving evidence of the devastation her death had brought to their lives.

   In mitigation Simmons’ attorneys first called an officer of the Missouri juvenile justice system, who testified that Simmons had no prior convictions and that no previous charges had been filed against him. Simmons’ mother, father, two younger half brothers, a neighbor, and a friend took the stand to tell the jurors of the close relationships they had formed with Simmons and to plead for mercy on his behalf. Simmons’ mother, in particular, testified to the responsibility Simmons demonstrated in taking care of his two younger half brothers and of his grandmother and to his capacity to show love for them.

   During closing arguments, both the prosecutor and defense counsel addressed Simmons’ age, which the trial judge had instructed the jurors they could consider as a mitigating factor. Defense counsel reminded the jurors that juveniles of Simmons’ age cannot drink, serve on juries, or even see certain movies, because “the legislatures have wisely decided that individuals of a certain age aren’t responsible enough.” Defense counsel argued that Simmons’ age should make “a huge difference to [the jurors] in deciding just exactly what sort of punishment to make.” In rebuttal, the prosecutor gave the following response: “Age, he says. Think about age. Seventeen years old. Isn’t that scary? Doesn’t that scare you? Mitigating? Quite the contrary I submit. Quite the contrary.”

   The jury recommended the death penalty after finding the State had proved each of the three aggravating factors submitted to it. Accepting the jury’s recommendation, the trial judge imposed the death penalty.

   Simmons obtained new counsel, who moved in the trial court to set aside the conviction and sentence. One argument was that Simmons had received ineffective assistance at trial. To support this contention, the new counsel called as witnesses Simmons’ trial attorney, Simmons’ friends and neighbors, and clinical psychologists who had evaluated him.

   Part of the submission was that Simmons was “very immature,” “very impulsive,” and “very susceptible to being manipulated or influenced.” The experts testified about Simmons’ background including a difficult home environment and dramatic changes in behavior, accompanied by poor school performance in adolescence. Simmons was absent from home for long periods, spending time using alcohol and drugs with other teenagers or young adults. The contention by Simmons’ postconviction counsel was that these matters should have been established in the sentencing proceeding.

After these proceedings in Simmons’ case had run their course, this Court held that the Eighth and Fourteenth Amendments prohibit the execution of a [developmentally disabled] person. Atkins v. Virginia, 536 U. S. 304 (2002). Simmons filed a new petition for state postconviction relief, arguing that the reasoning of Atkins  established that the Constitution prohibits the execution of a juvenile who was under 18 when the crime was committed.

   The Missouri Supreme Court agreed. State ex rel. Simmons v. Roper, 112 S. W. 3d 397 (2003) (en banc). It held that since Stanford,

“a national consensus has developed against the execution of juvenile offenders, as demonstrated by the fact that eighteen states now bar such executions for juveniles, that twelve other states bar executions altogether, that no state has lowered its age of execution below 18 since Stanford, that five states have legislatively or by case law raised or established the minimum age at 18, and that the imposition of the juvenile death penalty has become truly unusual over the last decade.” 112 S. W. 3d, at 399.

On this reasoning it set aside Simmons’ death sentence and resentenced him to “life imprisonment without eligibility for probation, parole, or release except by act of the Governor.” Id., at 413.

The prohibition against “cruel and unusual punishments,” like other expansive language in the Constitution, must be interpreted according to its text, by considering history, tradition, and precedent, and with due regard for its purpose and function in the constitutional design. To implement this framework we have established the propriety and affirmed the necessity of referring to “the evolving standards of decency that mark the progress of a maturing society” to determine which punishments are so disproportionate as to be cruel and unusual. Trop v. Dulles, 356 U. S. 86, 100–101 (1958) (plurality opinion).

***

A majority of States have rejected the imposition of the death penalty on juvenile offenders under 18, and we now hold this is required by the Eighth Amendment.

***

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”). It has been noted that “adolescents are overrepresented statistically in virtually every category of reckless behavior.” Arnett, Reckless Behavior in Adolescence: A Developmental Perspective, 12 Developmental Review 339 (1992). In recognition of the comparative immaturity and irresponsibility of juveniles, almost every State prohibits those under 18 years of age from voting, serving on juries, or marrying without parental consent. See Appendixes B–D, infra.

   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….

***

 As for deterrence, it is unclear whether the death penalty has a significant or even measurable deterrent effect on juveniles, as counsel for the petitioner acknowledged at oral argument. Tr. of Oral Arg. 48. In general we leave to legislatures the assessment of the efficacy of various criminal penalty schemes, see Harmelin v. Michigan, 501 U. S. 957, 998–999 (1991) (Kennedy, J., concurring in part and concurring in judgment). Here, however, the absence of evidence of deterrent effect is of special concern because the same characteristics that render juveniles less culpable than adults suggest as well that juveniles will be less susceptible to deterrence. In particular, as the plurality observed in Thompson, “[t]he likelihood that the teenage offender has made the kind of cost-benefit analysis that attaches any weight to the possibility of execution is so remote as to be virtually nonexistent.” 487 U. S., at 837. To the extent the juvenile death penalty might have residual deterrent effect, it is worth noting that the punishment of life imprisonment without the possibility of parole is itself a severe sanction, in particular for a young person.

***

 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.

 Justice O’Connor, dissenting.

   The Court’s decision today establishes a categorical rule forbidding the execution of any offender for any crime committed before his 18th birthday, no matter how deliberate, wanton, or cruel the offense. Neither the objective evidence of contemporary societal values, nor the Court’s moral proportionality analysis, nor the two in tandem suffice to justify this ruling.

   Although the Court finds support for its decision in the fact that a majority of the States now disallow capital punishment of 17-year-old offenders, it refrains from asserting that its holding is compelled by a genuine national consensus. Indeed, the evidence before us fails to demonstrate conclusively that any such consensus has emerged in the brief period since we upheld the constitutionality of this practice in Stanford v. Kentucky, 492 U. S. 361 (1989).

   Instead, the rule decreed by the Court rests, ultimately, on its independent moral judgment that death is a disproportionately severe punishment for any 17-year-old offender. I do not subscribe to this judgment. Adolescents as a class are undoubtedly less mature, and therefore less culpable for their misconduct, than adults. But the Court has adduced no evidence impeaching the seemingly reasonable conclusion reached by many state legislatures: that at least some 17-year-old murderers are sufficiently mature to deserve the death penalty in an appropriate case. Nor has it been shown that capital sentencing juries are incapable of accurately assessing a youthful defendant’s maturity or of giving due weight to the mitigating characteristics associated with youth.

 Justice Scalia, with whom The Chief Justice and Justice Thomas join, dissenting.

…. What a mockery today’s opinion makes of [Alexander] Hamilton’s expectation, announcing the Court’s conclusion that the meaning of our Constitution has changed over the past 15 years—not, mind you, that this Court’s decision 15 years ago was wrong, but that the Constitution has changed. The Court reaches this implausible result by purporting to advert, not to the original meaning of the Eighth Amendment, but to “the evolving standards of decency,” ante, at 6 (internal quotation marks omitted), of our national society. It then finds, on the flimsiest of grounds, that a national consensus which could not be perceived in our people’s laws barely 15 years ago now solidly exists. Worse still, the Court says in so many words that what our people’s laws say about the issue does not, in the last analysis, matter: “[I]n the end our own judgment will be brought to bear on the question of the acceptability of the death penalty under the Eighth Amendment.” Ante, at 9 (internal quotation marks omitted). The Court thus proclaims itself sole arbiter of our Nation’s moral standards—and in the course of discharging that awesome responsibility purports to take guidance from the views of foreign courts and legislatures. Because I do not believe that the meaning of our Eighth Amendment, any more than the meaning of other provisions of our Constitution, should be determined by the subjective views of five Members of this Court and like-minded foreigners, I dissent.
