How long can a juvenile be detained before appearing in court?

The correct answer highlights that a juvenile can be detained for up to 24 hours past the end of the day on which they were taken into custody before having to appear in court. This time frame is established to ensure that juveniles are given a prompt judicial review of their detention, in line with legal standards designed to protect minors' rights.

This regulation reflects the legal requirement to balance the need for law enforcement to take necessary actions with the rights and welfare of juvenile offenders. The maximum duration allows for sufficient time to process the situation while adhering to principles that recognize the vulnerabilities of minors. This consideration is vital in juvenile justice, which emphasizes rehabilitation rather than punishment.

The other durations presented do not align with the standard practices typically established in juvenile justice systems, which aim primarily to ensure timely judicial intervention and protect the rights of young individuals in custody.
