Prohibits sentencing individual under 21 years of age to life imprisonment.

This bill prohibits courts in New Jersey from sentencing individuals under 21 years old to life imprisonment without parole for certain serious crimes. It directly affects young offenders aged 18-20 convicted of qualifying offenses like murder, aggravated assault, or sexual offenses under specific statutes. The key provision amends sentencing law to explicitly exclude people under 21 from receiving life-without-parole sentences, aligning with a Massachusetts court ruling that found similar sentencing unconstitutional. The bill does not change sentencing for adults or for crimes committed by individuals 21 or older. It would take effect immediately upon enactment.
