IL SB3599

Raises the age threshold for jail detention limits from 12 years old to 17 years old in the Juvenile Court Act of 1987.

Minors under 17 years of age cannot be detained in a county jail or municipal lockup for more than 6 hours (reduced from 12 hours).

For crimes of violence, minors under 17 may be detained up to 24 hours instead of the standard 6-hour limit.

Eliminates previous provisions allowing minors 12 years and older to be confined in county jails for up to 40 hours pending adjudicatory hearings, and related detention standards.

Requires minors under 17 to be kept separate from confined adults and prohibits them from being held in the same cell, room, or yard as adult prisoners.
