Bucklew v. Precythe
The Supreme Court ruled that a death-row inmate challenging a specific execution method as unconstitutionally painful for him personally must still identify a feasible, available alternative method the state could use instead — the same rule that already applied to broader challenges against an execution method in general.
Because the inmate, Russell Bucklew, failed to present enough evidence that his proposed alternative (nitrogen gas) was truly workable or would meaningfully reduce his pain, the Court upheld the lower courts' decision to let Missouri proceed with his execution by lethal injection.
How it got here: A federal district court dismissed Bucklew's claim; the Eighth Circuit remanded for him to identify an alternative method; after further proceedings the district court granted summary judgment for the state, and the Eighth Circuit affirmed.
The Case in Depth
What happened
Russell Bucklew was convicted of murder, kidnapping, and rape after a 1996 crime spree, and was sentenced to death. He suffers from cavernous hemangioma, a rare disease causing blood-vessel tumors in his head, neck, and throat. He argued that Missouri's planned lethal-injection execution would cause him uniquely severe pain because his tumors could rupture or obstruct his airway, distinguishing his claim from a general attack on the drug protocol.
The question before the Court
A death-row inmate with a rare medical condition said lethal injection would cause him unique, severe pain. Did he have to prove there was a better available way for the state to execute him?
The Court's answer
Yes — the Court ruled that Bucklew had to identify a feasible, readily available alternative method of execution, just as inmates must in broader challenges to an execution method, because the constitutional question of whether a method inflicts unconstitutionally cruel pain is inherently a comparison between the state's chosen method and some other option, not an abstract judgment made alone.
Applying that rule, the Court found Bucklew's evidence too thin. He never showed his proposed alternative, nitrogen gas, could actually be carried out relatively easily, and he failed to show it would meaningfully reduce his pain compared to the state's lethal injection drug. As a result, the state was entitled to summary judgment, and Missouri could proceed with executing him by lethal injection.

Why it matters
Death-row inmates raising personalized, medical-condition-based objections to a state's execution method now face the same high bar as inmates mounting broad attacks on that method: they must name a specific, workable alternative. This makes it harder to delay or block executions through individualized pain claims, while also making clear the alternative need not be currently authorized by state law.
What changes now
This is a final decision on the merits, not a temporary order. The judgment upholding summary judgment for the state stands, clearing the way for Missouri to carry out Bucklew's execution by lethal injection. The ruling also sets the framework for future as-applied method-of-execution challenges nationwide, requiring inmates to identify workable alternatives regardless of how they frame their claims.
What this does not decide
The Court did not decide that any specific execution method, including lethal injection generally, is unconstitutional, nor did it resolve whether nitrogen hypoxia or the firing squad would satisfy the alternative-method test in other cases. It also did not adopt Justice Thomas's narrower 'deliberately designed to inflict pain' standard.
Concurrences and dissents
Concurrence — Justice Thomas
Justice Thomas would hold that a method of execution violates the Eighth Amendment only if the government deliberately designed it to inflict pain, without regard to the executioner's subjective intent. He joined the majority in full because it correctly applied existing precedent, but argued his narrower historical standard would have ended the inquiry immediately given no evidence Missouri designed its protocol to inflict pain.
Concurrence — Justice Kavanaugh
Justice Kavanaugh joined the majority but wrote separately to emphasize that all nine Justices agreed an inmate's proposed alternative method need not already be authorized under current state law. He highlighted that this makes the alternative-method burden easier to satisfy, pointing to the firing squad as one example an inmate might plead.
Dissent — Justice Breyer
Justice Breyer argued Bucklew presented enough evidence of prolonged suffocation and pain to survive summary judgment and reach a trial. He also argued the alternative-method requirement from Glossip should not extend to individualized, as-applied claims like Bucklew's, since such claims pose none of the risks of abolishing the death penalty that justified the rule in facial challenges. He would not have reached the delay-related commentary in Part IV.
Dissent — Justice Sotomayor
Justice Sotomayor joined Breyer's dissent except for its final part, and wrote separately to object to the majority's closing remarks about delay in capital litigation, calling them unnecessary dicta. She warned against treating last-minute stay requests as presumptively suspect and stressed that courts must carefully review even eleventh-hour constitutional claims in death penalty cases.
How the Court got there
The legal reasoning, step by step
- The Court read the Eighth Amendment's ban on 'cruel and unusual' punishment through its historical meaning: methods were cruel only if they deliberately 'superadded' terror, pain, or disgrace beyond what death itself required, not merely because they carried some risk of pain.
- Applying its precedents in Baze v. Rees and Glossip v. Gross, the Court held that to prove a method 'superadds' pain, an inmate must identify a feasible, readily implemented alternative method that would significantly reduce a substantial risk of severe pain, since assessing cruelty is inherently a comparative exercise rather than an abstract judgment made in isolation.
- The Court rejected the idea that as-applied challenges (aimed at one prisoner's unique situation) should be exempt from this alternative-method requirement, reasoning that the substantive meaning of the Eighth Amendment cannot shift depending on how broadly or narrowly a plaintiff frames his lawsuit.
- Turning to the facts, the Court found Bucklew's proposed alternative, nitrogen hypoxia, was not 'readily implemented' because he offered no evidence on basic administration questions like delivery method, concentration, or safety, and the state had a legitimate reason not to be the first to experiment with an untested method.
- Even assuming nitrogen hypoxia were viable, the Court concluded Bucklew failed to show it would significantly reduce his risk of pain compared with pentobarbital, because his expert's key testimony rested on a misread study of euthanasia in horses and did not show he would suffer meaningfully longer under the state's chosen drug.
