Juvenile Detention Rules
1. Introduction: Juvenile Detention
Juvenile detention refers to the temporary or long-term confinement of minors who have committed criminal offenses. The purpose is rehabilitation, education, and social reintegration, rather than purely punitive measures.
Key principles globally and in Finland:
Best interests of the child (UN Convention on the Rights of the Child, CRC).
Proportionality — detention only as a last resort.
Separation from adult offenders — to protect juveniles from harm.
Rehabilitation focus — education, counseling, and vocational training.
