Juvenile Justice

NACDL fully supports the concept that juveniles are different than adults and should be treated as such. NACDL encourages legislators to promote polices that evaluate juvenile family history and brain development prior to developing legislation that could in effect have profound implications on a juvenile's future.

The decision to send a youth to the adult system is a very serious one. Juveniles are different from adults and should be treated as such. The juvenile system is more focused on rehabilitation and provides more support and opportunities for juvenile offenders compared to adult criminal facilities. Substantial research has concluded youth dealt with in the juvenile system are far less likely to commit new crimes than those tried as adults.

Landmark Cases

Roper v. Simmons (2005) - The United States Supreme Court ruled in a 5-4 decision that it is unconstitutional to impose the death penalty for a crime committed by a child under the age of 18, stating that it is "cruel and unusual punishment" prohibited by the Eighth Amendment.

Graham v. Florida (2010) and Sullivan v. Florida (2010) - The United States Supreme Court ruled that life without the possibility of parole sentences for juveniles convicted of nonhomicide offenses are unconstitutional.

J.D.B v. North Carolina (2010) - Under consideration in this case was whether a child's age is a relevant factor to consider in determining whether the child is in custody for purposes of Miranda v. Arizona. The United States Supreme Court ruled that a child's age must be considered by law enforcement in determining whether Miranda warnings need to be given to children during police interrogations. NACDL Amicus Brief

Miller v. Alabama (2012) - Under consideration in this case was the constitutionality of imposing life without parole sentences on juveniles convicted of homicide offenses. The United States Supreme Court ruled that "mandatory life without parole for those under the age of 18 at the time of their crimes violates the Eighth Amendment's prohibition on 'cruel and unusual punishments' and that a 'judge or jury must have the opportunity to consider mitigating circumstances before imposing the harshest possible penalty for juveniles.'"

Montgomery v. Louisiana (2016) - Under consideration in this case was whether Miller v. Alabama applied retroactively to individuals serving mandatory juvenile life without parole sentences. In a 6-3 decision, the United States Supreme Court ruled that their decision in Miller v. Alabama applied retroactively. 

Jones v. Mississippi (2021) - Under consideration in this case was the constitutionality of imposing a life without parole sentence on a juvenile that has not been found to be permanently incorrigible. In a 6-3 decision, the United States Supreme Court ruled that a sentencing authority is not required to find a juvenile permanently incorrigible before imposing a life without parole sentence. NACDL Amicus Brief

In November 2020, NACDL partnered with Human Rights for Kids and Legal Aid Justice Center to host Major Changes in the Sentences of Minors: Recent Legal Updates in the Sentencing of Youth in Virginia, a free webinar to teach stakeholders about new developments in the treatment of juveniles facing adult court prosecution. Legislation passed in 2020 established that judges are no longer bound by mandatory minimum sentences and are directed to consider trauma, developmental factors, and other experiences that distinguish the experiences of youth in our criminal legal system.

State Juvenile Justice Reform

States across the country made significant legislative advancements to reform state youth justice systems. As of May 2024, more than half of states have abolished juvenile life without parole. Earlier in 2024, Massachusetts became the first state to ban life without parole sentences for individuals between the ages of 18-20. States have also made efforts to increase the use of diversion programs for youth, while also taking the necessary steps to address racial and ethnic disparities in the use of these diversion programs.

Consider joining NACDL’s State Criminal Justice Network (SCJN) to exchange information, share resources, and develop strategies for promoting rational and humane policies impacting children in the criminal legal system.
