No. Juveniles cannot get the death penalty in the United States. Since 2005, the Supreme Court has held that the Eighth and Fourteenth Amendments forbid executing anyone for a crime committed before their 18th birthday, and that rule applies in every state regardless of the offense. The controlling case is Roper v. Simmons, and no court can impose a capital sentence on a juvenile offender.1Cornell Law School. Roper v. Simmons
The Rule Set by Roper v. Simmons
In March 2005, the Supreme Court ruled 5–4 that the Constitution prohibits capital punishment for offenders who were under 18 at the time of their crime.1Cornell Law School. Roper v. Simmons Twenty states still allowed juvenile executions when the decision came down. It voided those laws and required new sentences for 72 people then on death row for crimes committed as minors.2Office of Justice Programs. Supreme Court Bans Death Penalty for Under-18 Offenders
The cutoff is the defendant’s age when the crime was committed, not their age at trial or sentencing. Someone who commits a capital-eligible offense at 17 and is not caught or tried until years later is still constitutionally protected from execution. Someone who commits the same offense a day after turning 18 is not.
Why the Court Banned It
Justice Anthony Kennedy, writing for the majority, grounded the decision in a straightforward idea: teenagers are fundamentally different from adults in ways that matter for punishment. The opinion identified three characteristics of adolescence. Juveniles lack the maturity and sense of responsibility that comes with age. They are more susceptible to outside pressure and negative influences. And their personalities are still forming, which means their worst acts are less likely to reflect a fixed, irredeemable character.3Justia. Roper v. Simmons, 543 U.S. 551
The Court leaned on research showing that the prefrontal cortex, which governs judgment and impulse control, doesn’t fully mature until well into a person’s twenties. That biological reality, the majority concluded, means juveniles have a greater capacity for change and rehabilitation than adults. Imposing a punishment designed to be final and irreversible on someone whose character is still forming struck the Court as disproportionate.
The legal doorway for that reasoning is the Eighth Amendment’s ban on cruel and unusual punishment. The Court reads that phrase as a moving standard, not a fixed one. The controlling formulation, from the 1958 case Trop v. Dulles, is that the Eighth Amendment “must draw its meaning from the evolving standards of decency that mark the progress of a maturing society.”4Justia. Trop v. Dulles, 356 U.S. 86 To measure where those standards sit, the Court looks primarily at what state legislatures have done. By the time Roper was decided, 30 states already prohibited the juvenile death penalty, either by rejecting capital punishment entirely or by exempting minors.3Justia. Roper v. Simmons, 543 U.S. 551 Actual practice pointed the same way: only 22 juvenile offenders had been executed in the nearly three decades since the death penalty was reinstated in 1976.
International practice was a secondary consideration. The United States was one of only a handful of countries still permitting juvenile executions, and the UN Convention on the Rights of the Child, ratified by 196 countries, explicitly prohibits capital punishment for offenses committed under 18.5OHCHR. Convention on the Rights of the Child The Court treated that as confirming evidence, not the basis for the ruling.
What Sentences a Juvenile Can Still Face
With death off the table, life without parole became the most severe sentence available for a juvenile offender. The Supreme Court has restricted that punishment too, though not eliminated it.
No LWOP for Non-Homicide Crimes
In Graham v. Florida (2010), the Court ruled that sentencing a juvenile to life without parole for a crime that did not involve a killing violates the Eighth Amendment.6Cornell Law School. Graham v. Florida A juvenile convicted of armed robbery, assault, or another serious non-homicide offense must be given what the Court called a “meaningful opportunity to obtain release” at some point during the sentence.7Justia. Graham v. Florida, 560 U.S. 48
No Mandatory LWOP for Homicide
Two years later, in Miller v. Alabama (2012), the Court struck down mandatory life-without-parole sentences for juveniles convicted of homicide.8Cornell Law School. Miller v. Alabama, 10-9646 The ruling did not ban LWOP outright for juvenile murderers. It required an individualized sentencing hearing that weighs the defendant’s age, maturity, home environment, and the circumstances of the offense before such a sentence can be imposed.
Jones v. Mississippi Loosened Miller
The protective trajectory stalled in 2021. In Jones v. Mississippi, the Court ruled 6–3 that a judge does not need to make a specific finding that a juvenile is “permanently incorrigible” before imposing life without parole.9Cornell Law School. Jones v. Mississippi The majority held that Miller requires only a discretionary sentencing process in which the judge considers the defendant’s youth. It does not require any particular finding, any particular explanation, or any particular outcome. In states that still allow juvenile LWOP for homicide, judges retain broad discretion to impose it after a hearing.
Where State Law Stands
Roughly 28 states have banned juvenile life without parole entirely through legislation or court rulings. About 22 states still allow it, though some have no one currently serving the sentence. States that provide a path to release differ in the details: some guarantee a parole hearing after 15 to 25 years, others allow a petition for resentencing after a set period. Where the crime occurred matters enormously for what a juvenile’s sentence actually looks like.
How a Juvenile Ends Up Facing Adult Sentences
These constitutional limits matter because juveniles can be tried as adults. Every state has at least one mechanism to move a juvenile case out of the juvenile system and into adult criminal court.10Office of Juvenile Justice and Delinquency Prevention. Juvenile Transfer to Criminal Court There are three main routes:
- Judicial waiver, where a juvenile court judge weighs the seriousness of the offense, the juvenile’s maturity, and prior record, then decides the case belongs in adult court. This is the most common method.
- Statutory exclusion, where state law automatically sends certain offenses, typically serious violent crimes like murder, to adult court once the juvenile meets a specified age. More than 30 states use some version of this.
- Direct file, where the prosecutor chooses the forum without needing a judge’s approval. About a dozen states allow this.
The age threshold varies. For statutory exclusion of serious offenses like murder, 16 is the most common cutoff, though some states set it as low as 13 or 14. Judicial waiver can reach defendants as young as 10 in a few states, though that is rare in practice. Some states also apply “once waived, always waived” rules, so a juvenile transferred to adult court once will have any future charges filed there automatically.10Office of Juvenile Justice and Delinquency Prevention. Juvenile Transfer to Criminal Court
Historically, fewer than 2% of formal juvenile delinquency cases are transferred through judicial waiver, and that figure excludes statutory exclusions and direct filings. For the small share that do land in adult court, the constitutional limits set out above become the ceiling: no execution for a crime committed before 18, no life without parole for a non-homicide, and no mandatory life without parole for anything.
