Does a juvenile life sentence with parole eligibility after a lengthy term violate the Eighth Amendment?

QUESTIONS PRESENTED Christopher Shanahan was convicted of first-degree murder and robbery in Idaho state court, crimes that he committed in 1995 when he was 15 years old. He was sentenced to life in prison, with 35 years before he is eligible for parole. In 2017, he filed a motion to correct an illegal — in Idaho District Court based on this Court’s recent line of cases that worked a fundamental change in constitutional law related to juvenile sentencing. The District Court denied the motion, and the Idaho Supreme Court affirmed that denial in a written opinion. Mr. Shanahan presents the following questions to this Court. 1. Does a juvenile life sentence, with parole eligibility after a lengthy term for years, in a state with no guarantee that the mitigating qualities of youth will ever be considered violate the Eighth Amendment’s prohibition against cruel and unusual punishment? 2. Must a Court reviewing an Eighth Amendment challenge to a juvenile offender’s adult prison sentence consider and assess the mitigating qualities of youth as a constitutional requirement? 3. Does a State violate equal protection of the law under the Fourteenth Amendment when it grants some juvenile offenders an opportunity to be resentenced but denies that same opportunity to other juvenile offenders who are within the same class?
