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

This bill (S 4351) amends New Jersey law to prohibit courts from sentencing individuals under 21 years old at the time of their crime to life imprisonment without parole. It directly affects young offenders convicted of certain serious offenses, such as murder or aggravated sexual assault, who would previously have been eligible for this sentence under existing law. The key provision explicitly states that courts "shall not impose a sentence of life imprisonment with no eligibility for parole" on anyone under 21 at the time of the crime. This change aligns with recent legal standards regarding sentencing for juvenile offenders.
