What it's about

The Supreme Court ruled that the Eighth Amendment bars laws requiring that sentence for juvenile homicide offenders, overturned the state court ruling in Miller’s case, and sent it back to the lower court (remanded).

Evan Miller was 14 when he committed a homicide and received a mandatory sentence of life in prison without parole.

The Court did not decide whether a judge may choose life without parole after considering an individual juvenile’s case.

Question presented

Does the imposition of a life-without-parole sentence on a fourteen-year-old child violate the Eighth and Fourteenth Amendments' prohibition against cruel and unusual punishment?

What the Court decided

Holding

The Eighth Amendment forbids a sentencing scheme that mandates life in prison without possibility of parole for juvenile homicide offenders. Pp. 6 − 27. No. 10 − 9646, 63 So. 3d 676, and No. 10 − 9647, 2011 Ark. 49, ___ S. W. 3d ___, reversed and remanded.
