imprisonment without the possibility of parole because the Supreme Court’s decision in Roper had invalidated the death penalty for juveniles. The Supreme Court first looked at its categorical bans on sentencing practices based on mismatches between culpability of a class of offenders and the severity of the penalty. The Supreme Court cited Roper, Graham, Kennedy v. Louisiana, 554 U.S. 407, 128 S.Ct. 2641, 171 L.Ed.2d 525 (2008), and Atkins. The Court also looked at cases where it had prohibited mandatory imposition of capital punishment, instead requiring that sentencing authorities consider the characteristics of a defendant and the details of the offense before sentencing the defendant to death, citing Woodson v. North Carolina, 428 U.S. 280, 804, 96 S.Ct. 2978, 49 L.Ed.2d 944 (1976) (<HOLDING>), and Lockett v. Ohio, 488 U.S. 586, 604, 98
holding that the mandatory sentencing scheme was flawed because it gave no significance to the character and record of the individual offender or the circumstances of the offense and excluded from consideration  the possibility of compassionate or mitigating factors holding that a trial court must not preclude the jury from considering any aspect of the defendants character or circumstances as a mitigating factor holding that juries may not be precluded from considering as a mitigating factor any aspect of a defendants character or record and any of the circumstances of the offense that the defendant proffers emphasis in original holding that juries may not be precluded from considering as a mitigating factor any aspect of a defendants character or record and any of the circumstances of the offense that the defendant proffers as a basis for a sentence less than death holding that sentencing scheme that permitted a limited range of mitigating evidence was unconstitutional because the eighth and fourteenth amendments require that the sentencer  not be precluded from considering as a mitigating factor any aspect of a defendants character or record and any of the circumstances of the offense that the defendant proffers as a basis for a sentence less than death
