Montgomery V. Louisiana Retroactivity Of Juvenile Sentencing
1. Montgomery v. Louisiana, 577 U.S. 190 (2016)
Overview:
Issue: Whether the U.S. Supreme Court’s ruling in Miller v. Alabama (2012)—which held mandatory life without parole (LWOP) for juveniles unconstitutional—applies retroactively to cases already final on direct review.
Background:
Henry Montgomery was sentenced to life without parole as a juvenile for a murder conviction in Louisiana.
Miller (2012) ruled mandatory LWOP for juveniles unconstitutional because it failed to consider the child’s age and capacity for reform.
Decision:
The Court held Miller’s rule is retroactive, meaning states must provide new sentencing hearings or parole eligibility for those sentenced before Miller.
Significance:
Allowed many juvenile lifers nationwide to seek resentencing or parole, emphasizing that children are constitutionally different from adults in sentencing.
Emphasized the Eighth Amendment’s protection against cruel and unusual punishment in juvenile cases.
2. Miller v. Alabama, 567 U.S. 460 (2012)
Overview:
Issue: Whether mandatory life without parole sentences for juveniles convicted of homicide violate the Eighth Amendment.
Background:
Two cases consolidated, including Evan Miller, sentenced to mandatory LWOP at age 14.
Decision:
Held mandatory LWOP for juveniles is unconstitutional.
Sentencers must consider the juvenile’s youth, immaturity, and potential for rehabilitation before imposing LWOP.
Significance:
Established a new standard requiring individualized sentencing for juveniles.
Laid groundwork for Montgomery’s retroactivity ruling.
3. Graham v. Florida, 560 U.S. 48 (2010)
Overview:
Issue: Whether LWOP sentences for juveniles convicted of non-homicide offenses violate the Eighth Amendment.
Decision:
Held that juveniles cannot be sentenced to LWOP for non-homicide crimes.
Significance:
First major ruling recognizing the developmental differences of juveniles in sentencing.
Emphasized hope for rehabilitation and eventual reintegration into society.
4. Roper v. Simmons, 543 U.S. 551 (2005)
Overview:
Issue: Whether imposing the death penalty on juvenile offenders violates the Eighth Amendment.
Decision:
Declared the death penalty unconstitutional for crimes committed under age 18.
Significance:
Recognized that juveniles have diminished culpability and greater capacity for change.
Paved the way for subsequent juvenile sentencing protections (Graham, Miller, Montgomery).
5. Welch v. United States, 578 U.S. 120 (2016)
Overview:
Issue: Whether a new substantive rule (like Miller) applies retroactively in federal cases on collateral review (e.g., habeas petitions).
Decision:
Held that new substantive rules, including those restricting sentencing, apply retroactively to cases on collateral review.
Connection to Montgomery:
Welch reaffirmed the principle of retroactivity for significant sentencing changes, supporting Montgomery’s retroactive application in state cases.
6. Jackson v. Hobbs, 579 U.S. 175 (2016) (companion case to Miller and Montgomery)
Overview:
Confirmed the Miller rule applies to juveniles sentenced before the ruling, emphasizing individualized sentencing.

| Jackson v. Hobbs | 2016 | Application of Miller’s ruling | Miller applies to juveniles sentenced pre-ruling | Reinforces individualized sentencing |
Explanation and Legal Impact
The Eighth Amendment’s prohibition on cruel and unusual punishment has been interpreted to require special protections for juveniles in sentencing due to their developmental differences.
The sequence from Roper → Graham → Miller → Montgomery represents the Court’s evolving approach recognizing juveniles’ diminished culpability and greater capacity for rehabilitation.
Montgomery clarified that these constitutional protections must be applied retroactively, allowing many juvenile offenders sentenced harshly before these rulings to seek relief.
The decision has spurred significant legislative and judicial reforms in state juvenile sentencing procedures.
