McKeiver v. Pennsylvania (1971) Explained
In the important case McKeiver v. Pennsylvania, the Supreme Court determined that the Constitution doesn’t require jury trials in juvenile delinquency proceedings. The Court found that jury trials might harm the informal protective nature of juvenile court proceedings. They worried jury trials would make the juvenile court too much like adult criminal court.
The Supreme Court recognized that while the Sixth Amendment guarantees the right to a trial by jury in criminal prosecutions, juvenile proceedings aren’t technically “criminal” cases. Instead, they’re considered “civil” cases aimed at helping rather than punishing. This distinction lets the Court deny juveniles the right to a jury while still following constitutional principles.
The justices were concerned that juries would turn juvenile proceedings into mini-adult criminal trials. They feared this would undermine the juvenile justice system’s goal of rehabilitation. The due process clause of the Constitution allows for this different treatment of juveniles.
California’s Approach to Juvenile Jury Trials
Following the Supreme Court’s guidance, California doesn’t give juvenile defendants the right to trial by jury, even for serious offenses. A judge alone decides if the evidence proves beyond a reasonable doubt that a juvenile committed the alleged crime. This standard of proof is the same as in adult criminal proceedings.
In rare cases, such as when a juvenile might be transferred to adult court through a “fitness hearing,” some jury-related rights may apply. If a case moves to adult criminal court, then all protections of adult criminal proceedings—including the right to a jury—would apply to the juvenile defendant.
California courts have repeatedly upheld this approach. The Juvenile Law Center and other advocacy groups sometimes challenge this system. They argue jury trials would better protect young defendants’ rights. However, the current system remains firmly in place across most states, including California.
