Relates to the age of persons eligible for a sentence of life imprisonment without parole

This bill clarifies that only individuals who were eighteen years of age or older at the time of committing a crime can be sentenced to life imprisonment without the possibility of parole. It directly affects the sentencing guidelines for serious offenses such as murder, terrorism, and the use of chemical or biological weapons by explicitly excluding minors from this specific punishment. The legislation ensures that defendants under the age of eighteen remain eligible for indeterminate sentences with a maximum term of life imprisonment, while those aged eighteen and above face the stricter penalty for the listed crimes. This change codifies the age restriction into the penal law and takes effect immediately upon passage.
