Changes criminal sexual conduct in the first degree (MCL 750.520b) to impose life imprisonment without parole for individuals 18 years or older (changed from 17) who commit sexual penetration against children under 13 with prior convictions for similar offenses.

Implements prospective and retroactive application procedures for addressing the U.S. Supreme Court's decision in Miller v. Alabama, which restricted mandatory life sentences without parole for juvenile offenders.

Increases penalties for certain crimes when they result in death, injury, or serious bodily impairment, with enhanced punishments ranging from 15 years to life imprisonment depending on the severity of harm caused.
