IL SB1560

Restricts commitment to Department of Juvenile Justice to minors at least 13 and under 20 years of age (previously could be older), and requires courts to include pre-custody credits and sentencing limitations based on adult penalty periods.

Prohibits commitment to Department of Juvenile Justice or detention for acts that would not be illegal if committed by an adult.

Establishes automatic aftercare release terms: 1.5 years for Class X felonies, 1 year for Class 1-2 felonies, and 6 months for Class 3 or lesser felonies, with discharge upon completion unless sooner terminated.

Requires courts to make detailed findings before commitment, including review of age, criminal history, educational background, mental health, and community-based services attempted, with emphasis on least restrictive alternatives.

Modifies aftercare violation warrant procedures to require actual filing of delinquency petitions rather than mere charges, and allows (rather than mandates) aftercare specialists to request violation warrants.
