Juvenile court describes, in practice, the forum for criminal proceedings against children and young people. It is a descriptive term; each jurisdiction uses its own formal structure.England and Wales: the youth court, a specialist magistrates’ court for 10–17-year-olds (serious cases may go to the Crown Court). Hearings are not in public, reporting restrictions generally apply, and there are adapted procedures, diversion and youth-specific sentencing.Scotland: most matters are dealt with by the children’s hearings system under the Children’s Hearings (Scotland) Act 2011, rather than a court. Prosecution of older children for serious offences proceeds in the sheriff or High Court with reporting restrictions. ‘Juvenile court’ is not used.Northern Ireland: the Youth Court, a sitting of the Magistrates’ Court for 10–17-year-olds, with closed hearings, statutory anonymity and tailored disposals, under youth justice legislation including the Justice (Northern Ireland) Act 2002.Ireland: the Children’s Court under the Children Act 2001 hears cases involving under-18s, generally in private, with strict reporting restrictions and access to diversion.Practitioners therefore use ‘juvenile court’ as convenient shorthand when comparing youth justice systems, but should identify the correct forum and applicable procedural and sentencing regimes.
