Summary — HB 4162 (Michigan): Prohibiting Life‑Without‑Parole Sentences for Offenders Under 19
Status & filing
- Bill number: HB 4162. Introduced March 10, 2025.
- Subject areas: criminal penalties, sentencing, juveniles, circuit court.
- Amends: multiple provisions of the Michigan Penal Code (1931 PA 328), including sections 16, 18, 200i, 204, 207, 209, 210, 211a, 316, 436, 543f, and adds section 506b.
- Tie‑bar: HB 4160, HB 4161, HB 4163, HB 4164 — related bills addressing parole eligibility, juvenile sentencing, and related public‑health penalties.
- Legislative status (recorded): placed on third reading (House actions in March 2025 include substitute adoption and House passage steps).
Purpose and intent
- To remove the possibility of imposing a life sentence without parole (LWOP) on persons who were under 19 years old at the time they committed certain very serious offenses, and to provide alternate sentencing and parole‑eligibility rules for those individuals. The bill is part of a package aimed at distinguishing juvenile/young‑adult culpability and expanding parole review for young offenders.
Key provisions (substantive changes)
- Prohibits LWOP for defendants who were less than 19 years old at the time of specified offenses that currently carry LWOP for adults.
- For those offenses committed by persons under 19, the bill replaces LWOP with a term‑of‑years sentence (the primary text provides a sentence range of imprisonment of not less than 10 years and not more than 60 years for affected offenses). (Note: some earlier draft language in companion/substitute drafts contained a 20‑year minimum for specific subsections; the most consistent enacted/introduced language uses a 10–60 year range.)
- Affected offenses include (non‑exhaustive list):
- First‑degree murder;
- Offenses causing death by adulterating/misbranding drugs or knowingly mixing poisonous/harmful substances;
- Manufacturing, delivering, possessing, releasing harmful biological/chemical/radioactive devices resulting in death;
- Use, placement, or distribution of explosives or incendiary devices causing death;
- Terrorism causing death;
- Placing poisons in food/water resulting in death.
- Cross‑code changes: the bill amends penalties in multiple penal code sections to implement the above age‑based penalty adjustments.
- Companion bills (noted tie‑bar):
- HB 4160 (Corrections Code): would make persons under 19 at offense eligible for parole board jurisdiction after serving 10 years of an LWOP or comparable life sentence; requires parole board to consider youth‑related factors (age/immaturity, family/home environment, role in offense, peer pressure) and to notify prosecutors before granting parole in certain cases.
- HB 4161: makes parallel adjustments in the Public Health Code for drug‑adulteration offenses committed when under 19.
- HB 4163: would amend juvenile sentencing rules (repeal provisions allowing juvenile LWOP or very long juvenile sentences for certain offenses).
Who is affected
- Individuals convicted of listed offenses who were younger than 19 at the time of the offense — they would no longer be eligible for LWOP and instead face a finite term (generally 10–60 years) with parole possibilities as provided in companion bills.
- Courts and sentencing judges (different statutory sentencing ranges to apply).
- Parole Board and Department of Corrections (new parole‑eligibility timing and required youth‑focused considerations).
- Prosecutors, victims, and communities (procedural changes such as required notice to prosecuting attorneys prior to certain parole grants).
Procedural/timing notes
- HB 4162 is part of a multi‑bill package; its full practical effect depends on related enactments (HB 4160–4164) that address parole procedures and juvenile sentencing code changes.
- Multiple substitute versions and edits were considered; readers should consult the most recent enrolled/substitute text for final minimum/maximum terms and cross‑references.
Notes and caveats
- Drafts and substitutes have varied somewhat (some language referenced a 20‑year minimum in certain versions). The summary above reflects the predominant introduced/substitute language replacing LWOP for offenders under 19 with a term in the 10–60 year range and expanding parole review mechanisms in companion bills.
- For final legal effect and precise sentencing language, consult the enacted statute text and any implementing guidance from the Michigan Legislature or Department of Corrections.
