After the Atkins ruling, Brumfield filed for post-conviction relief, claiming he was intellectually disabled and therefore could not be executed.

The state court rejected Brumfield's intellectual disability claim without holding an evidentiary hearing, concluding that he had failed to make a substantial threshold showing of intellectual disability.

Brumfield then sought federal habeas corpus review, arguing the state court's decision was "based on an unreasonable determination of the facts" under 28 U.S.C.

§ 2254(d)(2).

The Supreme Court agreed with Brumfield, holding that his evidence of intellectual disability was sufficient to warrant federal court consideration of his Atkins claim.

The key to the Court's ruling was that Brumfield's evidence satisfied the requirements of § 2254(d)(2), which allows for federal review if the state court decision was unreasonable.

The Court found the state court's rejection of Brumfield's intellectual disability claim without a hearing was an unreasonable determination of the facts.

This decision allowed Brumfield to have his Atkins claim evaluated on the merits in federal court, rather than being precluded by the state court's prior rejection.

The Brumfield case highlights the importance of the Atkins v.

Virginia ruling, which established that executing intellectually disabled individuals violates the Eighth Amendment's prohibition on cruel and unusual punishment.

It also demonstrates the role that the federal habeas corpus process can play in reviewing state court decisions that fail to properly consider evidence of intellectual disability.

The case was significant in expanding the rights of death row inmates to have their intellectual disability claims fully evaluated, even when previously rejected by state courts.

Brumfield v.

Cain underscores the ongoing efforts to ensure the Atkins ruling is properly implemented and that intellectually disabled individuals are not executed in violation of the Constitution.
