Montgomery v. Louisiana

2016-01-25

Headline: Retroactive ruling forces states to apply the 2012 Miller decision, giving people sentenced as juveniles to life without parole a chance at parole or resentencing and affecting long‑serving prisoners.

Holding: The Court held that Miller announced a substantive constitutional rule that must be applied retroactively on collateral review, so states must give people sentenced as juveniles to life without parole an opportunity to seek relief or parole.

Real World Impact:

Requires states to apply Miller retroactively to juvenile life-without-parole cases.
Gives long‑serving juvenile lifers a chance at parole or resentencing.
Reverses Louisiana's refusal and sends cases back for further proceedings.

Summary

Background

Henry Montgomery was 17 when he killed a deputy sheriff in Louisiana, was retried after a first conviction was set aside for prejudice, and received an automatic life‑without‑parole sentence that left him no chance to present youth or mitigation. Decades later the Court’s 2012 decision in Miller limited mandatory life‑without‑parole for juveniles, and Montgomery asked Louisiana courts to apply that decision to his long‑final sentence.

Reasoning

The Court considered whether Miller announced a substantive rule that must be applied retroactively on collateral review. It concluded Miller is substantive because it places limits on the State’s power to impose life without parole on most juvenile offenders: youth reduces blame and increases capacity to change, making automatic life terms disproportionately harsh. The majority explained that when a new substantive rule eliminates a State’s power to impose a punishment, the Constitution requires state collateral courts to give that rule retroactive effect.

Real world impact

The decision means many people who received mandatory life without parole as juveniles can seek relief. States may comply by allowing parole consideration or by resentencing, rather than automatically releasing everyone. Prisoners can present evidence of youth, immaturity, and rehabilitation; the ruling does not guarantee release, but restores a meaningful chance to avoid an otherwise disproportionate lifetime term. The Court reversed Louisiana’s denial and sent Montgomery’s case back for further proceedings.

Dissents or concurrances

Justice Scalia, joined by Justices Thomas and Alito, dissented, arguing the Court lacked jurisdiction and that the Constitution does not require states to apply new rules retroactively on state collateral review. Justice Thomas wrote separately emphasizing historical and textual limits on imposing retroactivity.
