What it's about

The Supreme Court considered whether the Constitution requires a judge to make a separate finding that a juvenile offender is permanently incorrigible before imposing life without parole.

The case tested how the Court's earlier decisions in Miller and Montgomery apply to life-without-parole sentences for people who committed killings before turning 18.

Question presented

Whether the Eighth Amendment requires the sentencing authority to make a finding that a juvenile is permanently incorrigible before imposing a sentence of life without parole.

What the Court decided

Holding

In the case of a defendant who committed a homicide when he or she was under 18, Miller and Montgomery do not require the sentencer to make a separate factual finding of permanent incorrigibility before sentencing the defendant to life without parole. In such a case, a discretionary sentencing system is both constitutionally necessary and constitutionally sufficient. 285 So. 3d 626, affirmed.

From the opinions

“Today, the Court guts Miller v. Alabama , 567 U. S. 460 (2012), and Montgomery v. Louisiana , 577 U. S. 190 (2016).”

— Justice Sotomayor(dissent)

What's next

The Supreme Court has finished its review. The lower court's ruling and Jones's life-without-parole sentence remain in place.

Why it matters

For people who committed killings before turning 18, it says a sentencing system that lets the judge choose among punishments meets the Constitution's requirements; no separate finding that the person can never change is required.
