The application for stay of execution of sentence of death presented to Justice KAGAN and by her referred to the Court is denied. The petition for a writ of certiorari is denied.

Justice SOTOMAYOR, with whom Justice BREYER joins, dissenting from denial of application for stay and denial of certiorari.

Once again, a State hastens to kill a prisoner despite mounting evidence that the sedative to be used, midazolam, will not prevent the prisoner from feeling as if he is "drowning, suffocating, and being burned alive from the inside out" during a process that could last as long as 18 minutes. Irick v. Tennessee , 585 U.S. ----, ----, 139 S.Ct. 1 , ----, --- L.Ed.2d ----, 2018 WL 3767151 (2018) (SOTOMAYOR, J., dissenting from denial of application for stay); see also Arthur v. Dunn , 580 U.S. ----, ----, 137 S.Ct. 725 , 725, 197 L.Ed.2d 225 (2017) (SOTOMAYOR, J., dissenting from denial of certiorari). And once again the State claims the right to do so under the Eighth Amendment not because a court has concluded that these risks are overblown, but rather because of the "perverse requirement that inmates offer alternative methods for their own executions." McGehee v. Hutchinson , 581 U.S. ----, ----, 137 S.Ct. 1275 , 1276, 197 L.Ed.2d 746 (2017) (SOTOMAYOR, J., dissenting from denial of application for stay and denial of certiorari); see also Glossip v. Gross , 576 U.S. ----, ---- - ----, 135 S.Ct. 2726 , 2737-2739, 192 L.Ed.2d 761 (2015). This requirement was legally and morally wrong when it was promulgated, and it has been proved even crueler in light of the obstacles that have prevented capital prisoners from satisfying this precondition. I would therefore grant a stay of execution and grant petitioner Edmund Zagorski's petition for certiorari to consider what suffices for a prisoner to prove "a known and available alternative method of execution." See Glossip , 576 U.S., at ----, 135 S.Ct., at 2737-2738 . 1

For several years, Tennessee has provided for the execution of capital prisoners via a single drug called pentobarbital. See Abdur'Rahman v. Parker , No. M2018-01385-SC-RDO-CV, --- S.W.3d ----, ---- - ----, 2018 WL 4858002 (Sup. Ct. Tenn., Oct. 8, 2018), pp. 3-4. Pentobarbital, a barbiturate, does not carry the risks described above; unlike midazolam (a benzodiazepine), pentobarbital is widely conceded to be able to render a person fully *12 insensate. See, e.g., Glossip, 576 U.S., at ----, 135 S.Ct., at 2733 .

In January 2018, Tennessee Department of Corrections (TDOC) adopted an alternative to pentobarbital : Protocol B, a three-drug sequence beginning with midazolam (the drug whose sedative properties are dubious), to be followed by vecuronium bromide (to paralyze the prisoner) and then potassium chloride (to stop the prisoner's heart). 2 No. M2018-01385-SC-RDO-CV, at 4, --- S.W.3d at ----. The pentobarbital option-Protocol A-remained, meanwhile, in effect. Ibid. In February 2018, the State set execution dates for several prisoners, including Zagorski, and Zagorski and others soon thereafter filed suit challenging Protocol B and pointing to Protocol A, pentobarbital, as the available, significantly less risky alternative. See id., at 4-5, --- S.W.3d, at ---- - ----. The State, however, was noncommittal about pentobarbital's availability. At a pretrial hearing in April 2018, as Justice Lee explained in dissent below, the trial court "zeroed in on the problem and repeatedly questioned counsel about the availability of pentobarbital," emphasizing that an answer to this question was " 'essential.' " Id., at 4, --- S.W.3d, at ----. "The State's response to the trial court's direct question-'will [Protocol A] be available for the August 9th execution?'-was 'I can't answer that question, Your Honor.' " Id., at 5, --- S.W.3d, at ----.

Then, "[j]ust a few hours before the parties filed their trial briefs on July 5, 2018, [TDOC] adopted a revised execution protocol that abandoned [pentobarbital], leaving only Protocol B"-the midazolam option. Id., at 4, --- S.W.3d, at ----. Trial commenced a few days later. Working on a highly expedited timeline, the trial court ruled against the prisoners later that month, concluding that they had failed to prove the availability of pentobarbital-the very method that TDOC had retained as Protocol A until just before trial started. 3 See Abdur'Rahman v. Parker , No. 18-183-II(III) (Ch. Ct. Davidson Cty., Tenn., July 26, 2018), pp. 2, 34. The Tennessee Supreme Court affirmed on that ground, while declining to "address the Plaintiffs' claim that the three-drug protocol creates a demonstrated risk of severe pain." No. M2018-01385-SC-RDO-CV, at 22, --- S.W.3d, at ----.

The circumstances surrounding Zagorski and his fellow prisoners' attempts to *13 prove that pentobarbital was "available" demonstrate how unfairly this already perverse requirement is being applied. For one, the prisoners' ability to prove the drug's availability was severely constrained by rules of secrecy surrounding individuals involved in the execution process. See id., at 3, --- S.W.3d, at ---- (Lee, J., dissenting); see also Tenn. Code Ann. § 10-7-504 (h) (2018). The prisoners were unable to depose individuals with direct knowledge of the State's efforts to obtain pentobarbital. Nor were the prisoners allowed to learn which potential sellers the State ostensibly approached to try to obtain pentobarbital. Short of cold-calling every pharmacy in the country and asking for pentobarbital, it is anyone's guess how the prisoners were supposed to challenge meaningfully the State's claim that it could not obtain the drug. Yet they were faulted below for failing to offer "direct proof." No. M2018-01385-SC-RDO-CV, at 21, --- S.W.3d, at ----.

Moreover, it is not as if pentobarbital has vanished from the Earth, for purposes of execution or otherwise. As Justice Lee noted in dissent, Texas and Georgia have each used it multiple times in executions this year alone. See No. M2018-01385-SC-RDO-CV, at 5, --- S.W.3d, at ----. Missouri also appears to be prepared to use it in upcoming executions. See, e.g., Brief for Respondent in Bucklew v. Precythe , O.T. 2018, No. 17-8151, p. 1. Moreover, what discovery the prisoners did obtain below indicates that roughly 10 of the 100 suppliers that TDOC reached out to in 2017 did have pentobarbital for sale-just not the number of doses that the State had requested. No. 18-183-II(III), at 13. And at least one supplier around this time evidently quoted a price and discussed a "bulk $ option." App. to Pet. for Cert. 197a.

The trial court found credible the senior TDOC officials who testified to having delegated a search for pentobarbital to their subordinates, see No. 18-183-II(III), at 11-12, and the Tennessee Supreme Court based its affirmance in significant part on these "credibility determinations," see No. M2018-01385-SC-RDO-CV, at 21-22, --- S.W.3d, at ---- - ----. But these senior officials were not the individuals who actually undertook the search for pentobarbital, see id., at 12 , --- S.W.3d, at ----; the actual procurers, by contrast, were unavailable to the prisoners because of the State's secrecy laws. When the prisoners tasked with asking the State to kill them another way are denied by the State information crucial to establishing the availability of that other means of killing, a grotesque requirement has become Kafkaesque as well.

Such barriers are not the only ways in which prisoners proposing a more humane means of execution may be thwarted. In other instances, courts have rejected claims by petitioners proposing means of execution that are unavailable under state law. See, e.g., Arthur , 580 U.S., at ----, 137 S.Ct., at 725 (SOTOMAYOR, J., dissenting from denial of certiorari). Such rejections are likewise troubling, because they suggest that "all a State has to do to execute [a person] through an unconstitutional method is to pass a statute declining to authorize any alternative method," id., at 729, and they likewise show the need for us to address in more detail what Glossip actually requires. In any event, the prisoners here sought only the State's own Protocol A, which the State itself had held out as a seemingly available method before eliminating it "on the eve of trial." No. M2018-01385-SC-RDO-CV, at 5, --- S.W.3d, at ---- (Lee, J., dissenting). That is hardly an extravagant request, particularly when the State's own evidence discloses that there had been opportunities to *14 purchase pentobarbital both in smaller quantities and in bulk.

I accordingly would grant Zagorski's request for a stay and grant certiorari to address what renders a method of execution "available" under Glossip . Capital prisoners are not entitled to pleasant deaths under the Eighth Amendment, but they are entitled to humane deaths. The longer we stand silent amid growing evidence of inhumanity in execution methods like Tennessee's, the longer we extend our own complicity in state-sponsored brutality. I dissent.
