Juvenile justice is a technical term that refers to the specific area of law and affiliated institutions, most notably the juvenile court, with jurisdiction over the cases of minors who are accused of being miscreants. Although the idea that the law should treat minors differently from adults predates the American Revolution, juvenile justice itself is a Progressive Era invention. Its institutional legitimacy rests on the power and responsibility of the state to act as a parent (parens patriae) on behalf of those who cannot care for themselves. Since the establishment of the world’s first juvenile court in Chicago in 1899, this American idea of creating separate justice systems for juveniles has spread across the nation and much of the world. For more than a century, American states have used their juvenile justice systems to respond to youth crime and delinquency. Since the 1960s, the US Supreme Court has periodically considered whether juvenile courts must provide the same constitutional due process safeguards as adult criminal courts and whether juveniles prosecuted in the criminal justice system can receive the same sentences as adults, such as the death penalty or life without the possibility of parole.
