Summary: written with AI from the case record.

What it's about
The Alabama Supreme Court’s decision allowing his death sentence to stand remained in effect.
The case came from Alabama’s highest court and involved Atkins v. Virginia, the 2002 Supreme Court decision named as the basis for Carroll’s Eighth Amendment claim.
Question presented
1. Whether the Eighth Amendment’s prohibition on cruel and unusual punishment, as interpreted in Atkins v. Virginia, 536 U.S. 304 (2002), and its progeny, requires that a defendant be permitted to present evidence of his intellectual disability at any time before he is executed. 2. Whether the Alabama Supreme Court’s rule that a defendant waives an Atkins claim by failing to raise it at trial or on direct appeal is an adequate state ground that bars federal review of the claim.
What the Court decided
Holding
Petition DENIED.
What's next
