A life sentence in Michigan lasts one of two very different lengths. If it’s life without the possibility of parole, it lasts the rest of the person’s natural life, with no scheduled review and no release date. If it’s a parolable life sentence, the prisoner becomes eligible for a parole review after 15 calendar years for crimes committed on or after October 1, 1992, or after 10 years for earlier crimes, though eligibility is not the same as release. Which track applies depends entirely on the offense of conviction.
Which Michigan Crimes Carry a Life Sentence
First-degree murder is the only offense in Michigan that carries a mandatory life-without-parole sentence. Under MCL 750.316, that includes premeditated murder, felony murder (a killing committed during certain violent crimes such as arson, robbery, carjacking, kidnapping, criminal sexual conduct, first-degree child abuse, or home invasion), and the murder of a peace officer or corrections officer.1Michigan Legislature. Michigan Compiled Laws 750-316 – First Degree Murder The judge has no discretion.
Several other offenses can produce a life sentence, but with parole eligibility built in. Second-degree murder is punishable by life or any term of years at the court’s discretion.2Michigan Legislature. Michigan Compiled Laws 750-317 – Second Degree Murder First-degree criminal sexual conduct carries the same range.3Michigan Legislature. Michigan Compiled Laws 750-520b – Criminal Sexual Conduct in the First Degree Certain high-quantity controlled substance offenses also carry life sentences with parole eligibility after extended minimum terms. For these crimes, the judge weighs the severity of the offense and the defendant’s background and chooses between a life sentence and a term of years.
When Life Means Life: Life Without Parole
A sentence of life without parole in Michigan means the person will die in prison unless something extraordinary happens outside the normal corrections process. There is no scheduled parole hearing. There is no good-time credit that shortens the sentence. The parole board has no jurisdiction over the case.
Only two things can change that outcome: a court overturning the conviction or sentence on appeal or post-conviction review, or the governor granting clemency. Both are rare. For the vast majority of people serving life without parole in Michigan, the sentence lasts until death.
When Parole Eligibility Kicks In on a Parolable Life Sentence
A parolable life sentence keeps the prisoner under the jurisdiction of the Michigan Parole Board. The timeline for the first parole review is set by MCL 791.234 and depends on when the offense occurred:4Michigan Legislature. Michigan Compiled Laws 791-234 – Prisoners Subject to Jurisdiction of Parole Board
- 15 calendar years for crimes committed on or after October 1, 1992.
- 10 calendar years for crimes committed before that date.
- 17.5 years for a major controlled substance offense with no prior serious crime conviction.
- 20 years for a major controlled substance offense with a prior serious crime conviction.
These are calendar years, not sentence credits. They mark the earliest point at which the board is required to review the case. Hitting that date does not entitle the prisoner to release; it triggers a review that can result in parole, continued incarceration, or scheduling of the next review years later.
What the Parole Board Weighs
Michigan’s administrative rules direct the parole board to look at nearly every aspect of a prisoner’s record and readiness.5Legal Information Institute. Michigan Administrative Code R 791.7715 – Factors Considered in Granting or Denying Parole The board considers the seriousness of the current offense and prior criminal history, institutional conduct (work and school performance, major misconduct, program completion), job skills and a realistic parole plan, demonstrated acceptance of responsibility, family and community ties, and any physical or mental health condition that reduces the risk of reoffending.
Victims and their families have a statutory right to submit an impact statement that the board must consider alongside the prisoner’s record.6Michigan Legislature. Michigan Code 780-765 – Oral Impact Statement at Sentencing If the victim cannot appear, an adult designee can speak on their behalf. These statements carry real weight in practice.
For lifers specifically, the board denies parole far more often than it grants it. Many people serving parolable life sentences spend decades past their eligibility date in prison, and some are never released. A clean disciplinary record, strong program completion, and credible insight into the offense give the best chance, but no combination of factors guarantees release.
Juveniles Sentenced to Life
The rules are different for people who were under 18 when the offense was committed. In Miller v. Alabama (2012), the U.S. Supreme Court held that mandatory life without parole for juveniles violates the Eighth Amendment, and judges must consider the defendant’s age, maturity, and capacity for change before imposing that sentence.7Justia U.S. Supreme Court Center. Miller v. Alabama, 567 U.S. 460 (2012) Montgomery v. Louisiana (2016) made that rule retroactive, entitling prisoners already serving mandatory juvenile life-without-parole sentences to new sentencing hearings.8Justia U.S. Supreme Court Center. Montgomery v. Louisiana, 577 U.S. 190 (2016)
Michigan’s response is MCL 769.25, enacted as Public Act 22 of 2014.9Michigan Legislature. Michigan Code 769-25 – Juvenile Sentencing A prosecutor who wants life without parole for a juvenile must file a motion within 21 days of conviction, and the court holds a Miller hearing on the defendant’s age, maturity, family environment, and the circumstances of the offense. If the prosecutor does not file, the court sentences the juvenile to a term of years instead.
Under MCL 769.25a, when a juvenile lifer is resentenced to a term of years (either because the prosecutor declined to seek life without parole again or missed the filing deadline), the minimum must fall between 25 and 40 years and the maximum is 60 years.10Michigan Courts. Juvenile LWOP Resentencing – Collateral Cases Victims may appear and give an oral impact statement at the resentencing.
Ways a Life Sentence Can Be Shortened or Undone
A life sentence in Michigan is not necessarily the end of the legal story, though the odds of shortening one are long. The main avenues:
Direct appeal. After conviction, the defendant can appeal to the Michigan Court of Appeals on grounds such as trial errors, improper jury instructions, prosecutorial misconduct, or ineffective assistance of counsel. An ineffective-counsel claim requires showing both that the lawyer’s performance fell below an objective standard of reasonableness and that the errors likely changed the outcome.
Motion for relief from judgment. Once direct appeals are exhausted, the main state-court option is a motion under Michigan Court Rule 6.500, filed in the original trial court.11Michigan Courts. Motion for Relief From Judgment Checklist It’s used for issues that couldn’t have been raised earlier, such as newly discovered evidence or a retroactive change in law. Only one such motion is allowed per conviction, with narrow exceptions. For claims that could have been raised on direct appeal but weren’t, the defendant must show both good cause for the omission and actual prejudice.
Federal habeas corpus. After state remedies are exhausted, a prisoner can petition a federal court under 28 U.S.C. ยง 2254, but only for claims that the custody violates the U.S. Constitution or federal law.12Office of the Law Revision Counsel. 28 U.S. Code 2254 – State Custody; Remedies in Federal Courts The deadline is one year from the date the state conviction became final, running from when the time for further state review expires. For claims based on a newly recognized constitutional right, the year runs from the date the Supreme Court recognized it. Federal courts grant relief in only a small fraction of cases.
Executive clemency. For someone serving life without parole, a commutation by the governor may be the only realistic path to release after appeals are exhausted. The application goes to the Michigan Parole Board, which reviews it for merit.13State of Michigan. Pardon and Commutation Application If the board finds merit and neither the sentencing judge nor the prosecutor objects, a public hearing is held, and the board forwards its findings to the governor. If the board finds no merit, the application still goes to the governor, who rarely grants clemency without a merit finding. An applicant may file only once every two years. A commutation reduces the sentence (for example, converting life without parole to a parolable life sentence or a term of years) but does not erase the conviction. Grants are exceedingly rare.
