Whether an Eighth Amendment method-of-execution claimant must identify a known and available alternative method that significantly reduces the risk of severe pain.
Holding
Yes. A prisoner challenging a method of execution must identify a feasible, readily implemented, known, and available alternative that would significantly reduce a substantial risk of severe pain.
Reasoning
The Court treated the controlling plurality opinion in Baze v. Rees as establishing the governing rule. Under Baze, a claimant must show both a demonstrated risk of severe pain under the State's method and that the risk is substantial compared with known and available alternatives. A marginally safer alternative is not enough, because some risk of pain is inherent in every execution and the Constitution does not require States to eliminate every such risk.
The Court rejected the prisoners' reliance on Hill v. McDonough. Hill held only that §1983 does not impose a special heightened pleading rule requiring a prisoner to identify an alternative method. It did not decide the substantive elements of an Eighth Amendment method-of-execution claim. Baze, by contrast, directly addressed those substantive elements.
The prisoners suggested a one-drug protocol using sodium thiopental or pentobarbital. But the lower courts found that neither drug was available to Oklahoma despite the State's good-faith efforts to obtain it, and the Supreme Court saw no clear error in that finding. Because the prisoners identified no other available alternative, they were not likely to succeed on their Eighth Amendment claim.
