## SUPREME COURT OF THE UNITED STATES

THOMAS D. ARTHUR v. JEFFERSON S. DUNN,

COMMISSIONER, ALABAMA DEPARTMENT OF CORRECTIONS, ET AL

.
ON PETITION FOR WRIT OF CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE ELEVENTH CIRCUIT
No. 16–602. Decided February 21, 2017

The motion of Certain Medical Professionals and Medi

cal Ethicists for leave to file a brief as amici curiae is granted. The petition for a writ of certiorari is denied.

J USTICE S OTOMAYOR , with whom J USTICE B REYER joins, dissenting from the denial of certiorari. Nearly two years ago in Glossip v. Gross , 576 U. S. ___ (2015), the Court issued a macabre challenge. In order to successfully attack a State’s me thod of execution as cruel and unusual under the Eighth Amendment, a condemned prisoner must not only prov e that the State’s chosen method risks severe pain, but must also propose a “known and available” alternative meth od for his own execution. Id ., at ___, ___ (slip op., at 13, 15). Petitioner Thomas Arthur, a prisoner on Alabama’s death row, has met this challenge. He has amassed signif

icant evidence that Alabama’s current lethal-injection protocol will result in intole rable and needless agony, and he has proposed an alternativ e—death by firing squad. The Court of Appeals, without considering any of the evidence regarding the risk posed by the current protocol, denied Arthur’s claim because Alabama law does not expressly permit execution by firing squad, and so it can

not be a “known and available” alternative under Glossip

. Because this decision permits States to immunize theirmethods of execution—no matter how cruel or how unusual—from judicial review and thus permits state law to subvert the Federal Constitution, I would grant certiorari2 ARTHUR v. DUNN

and reverse. I dissent from my colleagues’ decision not to do so.

I A Execution by lethal injection is generally accomplishedthrough serial administration of three drugs. First, a fastacting sedative such as sodium thiopental induces “a deep, comalike unconsciousness.” Baze v. Rees , 553 U. S. 35, 44 (2008) (plurality opinion). Second, a paralytic agent—most often pancuronium bromide—“inhibits all muscularskeletal movements and, by paralyzing the diaphragm, stops respiration.” Ibid . Third, potassium chloride in

duces fatal cardiac arrest. Ibid

. The first drug is critical; without it, the prisoner faces the unadulterated agony of the second and third drugs. The second drug causes “an extremely painful sensation of crushing and suffocation,” see Denno, When Legislatures Delegate Death: The Troubling Paradox Behind State Uses of Electrocution and Lethal Injection and What It Says About Us, 63 Ohio St. L. J. 63, 109, n. 321 (2002); but paralyzes the prisoner so as to “mas[k] any outward sign of distress,” thus serving States’ interest “ ‘in preserving the dignity of the procedure,’ ” Baze , 553 U. S., at 71, 73 (Stevens, J., concurring in judgment). And the third drug causes an “excruciating burning sensation” that is “equivalent to the sensation of a hot poker being inserted into the arm” and traveling “with the chemical up the prisoner’s arm and . . . across his chest until it reaches his heart.” Denno, supra , at 109, n. 321. Execution absent an adequate sedative thus produces a nightmarish death: The condemned prisoner is conscious but entirely paralyzed, unable to move or scream his agony, as he suffers “what may well be the chemical equivalent of being burned at the stake.” Glossip , 576 U. S., at ___ (S OTOMAYOR , J., dissenting) (slip op., at 2).3 Cite as: 580 U. S. ____ (2017)

B For many years, the barbiturate sodium thiopental seemed up to this task. 1 In 2009, however, the sole Ameri

can manufacturer of sodium thiopental suspended domes

tic production and later left the market altogether. Id. , at ___–___ (majority opinion) (slip op., at 4–5). States then began to use another barbiturate, pentobarbital. Id., at___ (slip op., at 5). But in 2013, it also became unavailable. Id., at ___–___ (slip op., at 5–6). Only then did States turn to midazolam, the drug at the center of this case. Midazolam, like Valium and Xanax, belongs to a class of medicines known as benzodiazepines and has some anes

thetic effect. Id. , at ___ (S OTOMAYOR , J., dissenting) (slip op., at 5). Generally, anesthetics can cause a level of sedation and depression of el ectrical brain activity suffi

cient to block all sensation, including pain. App. to Pet. for Cert. 283a–290a. But it is not clear that midazolam adequately serves this purpose. This is because midazo

lam, unlike barbiturates such as pentobarbital, has no analgesic—pain-relieving—effects. Id., at 307a; see also Glossip , 576 U. S., at ___ (S OTOMAYOR , J., dissenting) (slip op., at 5). Thus, “for midazolam to maintain unconscious

ness through application of a particular stimulus, it would need to depress electrical activity to a deeper level than would be required of, for exampl e, pentobarbital.” App. to

1 We examined the constitutiona lity of lethal injection in Baze v. Rees

, 553 U. S. 35 (2008). There, the parties did not dispute that “proper administration of . . . sodium thiope ntal . . . eliminates any meaningful risk that a prisoner would experi ence pain” and results in a humane death. Id ., at 49 (plurality opinion). The petitioners nonetheless challenged Kentucky’s three-drug prot ocol on the ground that, if prison executioners failed to follow the ma ndated procedures, an unconstitu

tional risk of significant pain would result. Ibid . A plurality of the Court concluded that “petitioners ha[d] not carried their burden of showing that the risk of pain from maladministration of a concededly humane lethal injection protocol” woul d violate the prohibition on cruel and unusual punishments. Id ., at 41.4 ARTHUR v. DUNN

S OTOMAYOR , J., dissenting

Pet. for Cert. 307a. 2 Although it can be used to render individuals unconscious, midazolam is not used on its own
to maintain anesthesia—complete obliviousness to physi

cal sensation—in surgical procedures, and indeed, the Food and Drug Administration has not approved the drug for this purpose. Glossip , 576 U. S., at ___ (S OTOMAYOR , J., dissenting) (slip op., at 5). Like the experts in Glossip , the experts in this case agree that midazolam is subject to a ceiling effect, which means that there is a point at which increasing the dose of the drug does not result in any greater effect. Ibid . The main dispute with respect to midazolam relates to how this ceiling effect operates—if the ceiling on midazolam’s sedative effect is reached be fore complete unconsciousness can be achieved, it may be incapable of keeping individu

als insensate to the extreme pain and discomfort associated with administration of the second and third drugs in lethal-injection protocols. Ibid. After the horrific execution of Clayton Lockett, who, notwithstanding administration of midazolam, awoke during his execution and appeared to be in great pain, we agreed to hear the case of death row inmates seeking to avoid the same fate. In Glossip , these inmates alleged that because midazolam is incapable of rendering prison

ers unconscious and insensate to pain during lethal injec

tion, Oklahoma’s intended use of the drug in their execu

2 Because “midazolam is not an analgesic drug, any painful stimulus applied to an inmate will generate and transmit full intensity pain signals to the brain without interference.” App. to Pet. for Cert. 309a. Arthur’s expert witness provides “a rough analogy”: “[ I ]f being sedated is like being as leep, analgesia is like wearing earplugs. If two people are sleepin g equally deeply, but only one is wearing earplugs, it will be much ea sier to shout and wake the person who is not wearing earplugs. If two people are sedated to equivalent levels of electrical brain activity, but only one has analgesia, the person sedated without analgesia will be mu ch more easily aroused to con

sciousness by the application of pain.” Ibid

tions would violate the Eighth Amendment. The Court rejected this claim for two reasons. First, the Court found that the District Court had not clearly erred in determining that “midazolam is highly likely to render a person unable to feel pain during an execution.” Id. , at ___ (slip op., at 16). Second, the Court held that the petitioners had failed to satisfy the novelrequirement of pleading and proving a “known and available alternative” method of execution. Id ., at ___ (slip op., at 15). Post- Glossip , in order to prevail in an Eighth Amend

ment challenge to a State’s me thod of execution, prisoners first must prove the State’s current method “entails a substantial risk of severe pain,” id

., at ___ (slip op., at 2), and second, must “identify a known and available alterna

tive method of execution that entails a lesser risk of pain,” id

., at ___ (slip op., at 1).

II
This case centers on whether Thomas Arthur has metthese requirements with respect to Alabama’s lethalinjection protocol.

A Alabama adopted lethal injection as its default method of execution in 2002. Ala. Code §15–18–82.1(a) (2011); see also Ex parte Borden , 60 So. 3d 940, 941 (Ala. 2007). The State’s capital punishment statute delegates the task of prescribing the drugs necessary to compound a lethal injection to the Department of Corrections. §15–18– 82.1(f ). Consistent with the practice in other States fol

lowing the national shortage of sodium thiopental and pentobarbital, the department has adopted a protocol involving the same three drugs considered in Glossip . See Brooks v. Warden , 810 F. 3d 812, 823 (CA11 2016). Perhaps anticipating constitutional challenges, Ala

-6 ARTHUR v. DUNN

S OTOMAYOR , J., dissenting
bama’s legislature enacted a contingency plan: The statute provides that “[i]f electrocution or lethal injection is held to be unconstitutional . . . all persons sentenced to death for a capital crime shall be executed by any constitutional method of execution.” §15–18–82.1(c).

B Thomas Douglas Arthur k illed his paramour’s husband in 1982. 840 F. 3d 1268, 1272–1273 (CA11 2016). Over the next decade, two juries found Arthur guilty of murder, and each time, Arthur’s conviction was overturned on appeal. Ibid . After a third trial in 1992, Arthur was convicted and sentenced to death. Ibid. Since then, Ar

thur has been scheduled to die on six separate occasions, and each time, his execution was stayed. Id., at 1275, n. 2. After 34 years of legal challenges, Arthur has accepted that he will die for his crimes. He now challenges only how the State will be permitted to kill him. Arthur asserted two distinct claims in the District Court. First, Arthur asserted a facial challenge, arguing that midazolam is generally incapable of performing as intended during Alabama’s three-drug lethal-injection procedure. Second, Arthur asserted an as-applied chal

lenge, arguing that because of his individual health at

tributes, midazolam creates a substantial risk of severe pain for him during the procedure. The District Court considered these two claims sepa

rately. With respect to the fa cial challenge, the District Court ordered bifurcated proceed ings, with the first hear

ing limited to the availability of a feasible alternative method of execution. App. to Pet. for Cert

. 189a, and n. 2. Arthur’s initial complaint propos ed a single dose either ofpentobarbital or sodium thiopental rather than a threedrug protocol, but the District Court found that those methods were unavailable given the elimination of both drugs from the domestic market. Id., at 203a–205a.7 Cite as: 580 U. S. ____ (2017)

S OTOMAYOR , J., dissenting
Arthur then moved to amend his complaint to allege the firing squad as an alternative method of execution. The District Court denied the moti on, holding that “execution by firing squad is not permitted by statute and, therefore, is not a method of execution that could be considered either feasible or readily implemented by Alabama at this time.” Id., at 241a. Because Arthur’s claim failed on this ground, the court never considered Arthur’s evidence with respect to midazolam, despite later observing that it was “impressive.” Id., at 166a. In a separate order, the District Court considered Ar

thur’s as-applied challenge. Arthur alleged, based on the expert opinion of Dr. Jack Strader, that “his cardiovascu

lar issues, combined with his age and emotional makeup, create a constitutionally unacceptable risk of pain that will result in a violation of the Eighth Amendment if he is executed under the [mid azolam] protocol.” Id., at 151a. Echoing its rationale with resp ect to Arthur’s facial chal

lenge, the District Court found that Arthur failed to prove the existence of a feasible, readily available alternative. The court then turned to the question it had avoided in the facial challenge: whether Alabama’s lethal-injection protocol created a risk of serious illness or needless suffer

ing. But because the District Court considered the ques

tion as part of Arthur’s as-applied challenge, it focused on the protocol as applied to Art hur’s personal physical condi

tion. The court rejected Dr. Strader’s opinion that the dose of midazolam required by Alabama’s protocol “will likely induce a rapid and dangerous reduction in blood pressure more quickly than it results in sedation,” and that during this time gap, Arthur—whom he believed to suffer from heart disease—would suffer a painful heart attack. Id., at 169a. Because Dr. Strader’s experience was limited to clinical doses of midazolam, which typically range from 2 to 5 mg, the court concluded that he had no basis to extrapolate his experience to non-clinical, lethal8 ARTHUR v. DUNN

S OTOMAYOR , J., dissenting
doses, such as the 500-mg bolus required by Alabama’s lethal-injection protocol. Id., at 177a. The District Court expressly refused to consider the expert opinions that Arthur pro ffered as part of his facial challenge, noting that they “are untested in court, due to Arthur’s inability to provide a[ n alternative] remedy in his facial, and now as-applied, challenges.” Id., at 167a, n. 16. The District Court therefore concluded that Arthur failed to meet the Glossip standard and entered judgment in favor of the State. App. to Pet. for Cert. 238a.

C The Eleventh Circuit affirmed. In a 111-page slip opin

ion issued the day before Arthur’s scheduled execution, the court first found that “Arthur never showed Alabama’s current lethal injection protocol, per se or as applied to him, violates the Constitution.” 840 F. 3d, at 1315. The court based this finding on Arthur’s failure to “satisfy the first [ Glossip ] prong as to midazolam” as part of his asapplied challenge, ibid. , and the fact that this Court “up

held the midazolam-based execution protocol” in Glossip

, 840 F. 3d, at 1315. Like the District Court, the Eleventh Circuit never considered the evidence Arthur introduced in support of his facial challenge to the protocol. Then, “[a]s an alternative and independent ground,” ibid. , the Court of Appeals found that the firing squad is not an available alternative because that method is “beyond [the Depart

ment of Corrections’] statutory authority,” id ., at 1320. Finally, and as yet another independent ground for deny

ing relief, the court held A rthur’s motion regarding the firing squad barred by the doctrine of laches. Ibid., n. 35.According to the Eleventh Circuit, the “known and available” alternative requirement was made clear in Baze — not Glossip —and because Arthur failed to amend his complaint in 2008 when Baze was decided, his claim was barred by laches.9 Cite as: 580 U. S. ____ (2017)

S OTOMAYOR , J., dissenting
On the day of his scheduled execution, Arthur filed a petition for certiorari and an application to stay his execu

tion. The Court granted the stay, 580 U. S. ___ (2016), but now denies certiorari.

III A The decision below permits a State, by statute, to bar a death-row inmate from vindicating a right guaranteed by the Eighth Amendment. Under this view, even if a pris

oner can prove that the State plans to kill him in an intol

erably cruel manner, and even if he can prove that there is a feasible alternative, all a St ate has to do to execute him through an unconstitutional me thod is to pass a statute declining to authorize any alternative method. This can

not be right. To begin with, it contradicts the very decisions it pur

ports to follow— Baze and Glossip

. Glossip based its “known and available alternative” requirement on the plurality opinion in Baze

. Baze , in turn, states that “[t]o qualify, the alternative procedur e must be feasible, readily implemented, and in fact significantly reduce a substan

tial risk of severe pain.” 553 U. S., at 52 (plurality opin

ion). The Court did not mention—or even imply—that a State must authorize the alter native by statute. To the contrary, Baze held that “[i]f a State refuses to adopt such an alternative in the face of these documented ad

vantages,” its “ refusal to change its method can be viewed as ‘cruel and unusual’ under the Eighth Amendment.” Ibid. (emphasis added). The decision below turns this language on its head, holding that if the State refuses to adopt the alternative legislatively, the inquiry ends. That is an alarming misreading of Baze

. Even more troubling, by co nditioning federal constitu

tional rights on the operation of state statutes, the deci

sion below contravenes basic constitutional principles.10 ARTHUR v. DUNN

S OTOMAYOR , J., dissenting
The Constitution is the “supreme law of the land”— irrespective of contrary state laws. Art. VI, cl. 2. And for more than two centuries it has been axiomatic that this Court—not state courts or legi slatures—is the final arbiter of the Federal Constitution. See Marbury v. Madison , 1 Cranch 137, 177 (1803). Acting within our exclusive “province and duty” to “say what the law is,” ibid ., we have interpreted the Eighth Amendment to entitle prison

ers to relief when they succeed in proving that a State’s chosen method of execution poses a substantial risk of severe pain and that a constitutional alternative is “known and available,” Glossip , 576 U. S., at ___–___ (slip op., at 1–2). The States have no power to override this constitutional guarantee. While States are free to define and punish crimes, “state laws respecting crimes, punish

ments, and criminal procedure ar e . . . subject to the over

riding provisions of the United States Constitution.” Payne v. Tennessee , 501 U. S. 808, 824 (1991). Equally untenable are the differing interpretations of the Eighth Amendment that would result from the Elev

enth Circuit’s rule. Under the Eleventh Circuit’s view, whether an inmate who will die in an intolerably cruel manner can obtain relief under Glossip depends not on the Constitution but on vagaries of state law. The outcome of this case, for instance, would turn on whether Arthur had been sentenced in Oklahoma, where state law expressly permits the firing squad, see Okla. Stat., Tit. 22, §1014 (Supp. 2016), rather than in Alabama, which—according to the Eleventh Circuit 3 —does not, see Ala. Code §15–18–

——————

3 I question the Eleventh Circuit’s conclusion that the statute does not authorize the firing squad as an available means of execution. In my view, the Alabama statute unambiguously reads as a codification of Glossip . If either of the specified methods—lethal injection or electrocu

tion—is declared unconstitutional, th e statute authorizes the State to execute prisoners by “ any constitutional method of execution.” Ala. Code §15–18–82.1(c) (2016) (emphasis added). The state statute11 Cite as: 580 U. S. ____ (2017)

S OTOMAYOR , J., dissenting

82.1. But since the very beginning of our Nation, we have emphasized the “necessity of uniformity” in constitutional interpretation “throughout the whole United States, upon all subjects within the purview of the constitution.” Mar

tin v. Hunter’s Lessee , 1 Wheat 304, 347–348 (1816) (em

phasis deleted). Nowhere is the need for uniformity more pressing than the rules governing States’ imposition of death.

B The Eleventh Circuit’s alternative holdings are unavailing. First, the court erroneously concluded that Arthur failed to carry his burden on the first Glossip requirement— proving that Alabama’s midazolam-centered protocol poses a substantial risk of severe pain. The court used the District Court’s finding that Arthur failed to meet this prong with respect to his as-applied challenge to hold that Arthur’s facial challenge likewise failed. But it is undis

puted that Arthur put forth “impressive” evidence to support his facial challenge t hat neither the District Court nor the Court of Appeals considered. This evidence in

cluded the expert testimony of Dr. Alan Kaye, chairman of the Department of Anesthesiology at Louisiana State University’s Health Sciences Center, who found the dose of midazolam prescribed in Alabama’s protocol insufficient to “cure . . . the fundamental unsuitability of midazolam as the first drug in [Alabama’s le thal-injection] protocol.” App. to Pet. for Cert. 302a (emphasis added). Dr. Kaye

—————— thus permits exactly what the Court required in Glossip —if a con

demned prisoner can prove that the lethal-injection pr otocol presents an unconstitutional risk of needle ss suffering, he may propose an alternative, constitutional means of execution, which may include the firing squad. Even assuming, ho wever, that the Eleventh Circuit properly interpreted Alabama’s stat ute, the question remains whether States may legislatively determ ine what the Eighth Amendment requires or prohibits. That qu estion is worthy of our review.12 ARTHUR v. DUNN

S OTOMAYOR , J., dissenting
concluded that “the chemical properties of midazolam limit its ability to depress electrical activity in the brain. The lack of another chemical property—analgesia— renders midazolam incapable of maintaining even that limited level of depressed electrical activity under the undiminished pain of the second and third lethal injection drugs.” Id ., at 311a. The court next read Glossip as categorically “uph[olding] the midazolam-based execution protocol.” 840 F. 3d, at 1315. Glossip did no such thing. The majority opinion in Glossip concluded that, based on the facts presented in that case, “[t]he District Court did not commit clear error when it found that midazolam is highly likely to render a person unable to feel pain during an execution.” 576 U. S., at ____ (slip op., at 16). The opinion made no determina

tion whether midazolam-centered lethal injection repre

sents a constitutional method of execution. Finally, the court’s laches finding faults Arthur for failing to act immediately after Baze , which, according to the panel, “made clear in 2008 . . . that a petitioner-inmate had the burden to show that a proffered alternative was ‘feasible, readily implemented, and in fact significantly reduced a substantial risk of pain.’ ” 840 F. 3d, at 1320,

n. 35 (quoting Baze , 553 U. S., at 41). But the District Court in this case—not to mention at least four Justices of this Court, see Glossip , 576 U. S., at ___–___ (S OTOMAYOR , J., dissenting) (slip op., at 24–27)—did not read Baze as requiring an alternative. See Record in Arthur v. Myers

, No. 2:11–cv–438 (MD Ala.), Doc. 195, p. 11 (“[T]he court does not accept the State’s argument that [a known and available alternative method of execution] is a specific pleading requirement set forth by Baze that must be properly alleged before a case can survive a motion to dismiss”). Arthur filed a statement within 14 days of our decision in Glossip informing the District Court of his belief that our decision would impact his case, see id. , Doc.13 Cite as: 580 U. S. ____ (2017)

S OTOMAYOR , J., dissenting
245, and moved to amend his complaint a few weeks later,

see id. , Doc. 256. In sum, the Eleventh Circuit’s opinion rests on quick

sand foundations and flouts the Constitution, as well as the Court’s decisions in Baze and Glossip . These errors alone counsel in favor of certiorari.

IV The decision below is all the more troubling because it would put an end to an ongoing national conversation— between the legislatures and the courts—around the methods of execution the Constitution tolerates. The meaning of the Eighth Amendment’s prohibition on cruel and unusual punishments “is determined not by the standards that prevailed when the Eighth Amendment was adopted in 1791” but instead derives from “ ‘the evolv

ing standards of decency that mark the progress of a maturing society.’ ” Kennedy v. Louisiana , 554 U. S. 407, 419 (2008) (quoting Trop v. Dulles , 356 U. S. 86, 101 (1958) (plurality opinion)). Evolving standards have yielded a familiar cycle: States develop a method of execu

tion, which is generally accepted for a time. Science then reveals that—unknown to the previous generation—the States’ chosen method of exec ution causes unconstitutional levels of suffering. A new method of execution is devised, and the dialogue continues. The Eighth Amendment requires this conversation. St ates should not be permitted to silence it by statute.

A From the time of the founding until the early 20th cen

tury, hanging was the preferred practice. Gardner, Execu

tions and Indignities—An Eighth Amendment Assessment of Methods of Inflicting Capital Punishment, 39 Ohio St. L. J. 96, 119 (1978). After several grotesque failures at the gallows—including slow asphyxiation and violent14 ARTHUR v. DUNN

S OTOMAYOR , J., dissenting
decapitation—revealed the “crude and imprecise” nature of the practice, Campbell v. Wood , 511 U. S. 1119, 1122 (1994) (Blackmun, J., dissenting from denial of certiorari), States sought to execute condemned prisoners “ ‘in a less barbarous manner’ ” and settled on electrocution. See In re Kemmler , 136 U. S. 436, 444 (1890). New York carried out the world’s first electrocution in ghastly fashion, 4 leading the New York Times to declare it “a disgrace to civilization.” See Far Worse Than Hanging, N. Y. Times, Aug. 7, 1890, p. 1. Electrocution nonetheless remained the dominant mode of execution for more than a century, until the specter of charred and grossly disfigured bodies proved too much for the public, and the courts, to bear. 5 See, e.g., Dawson v. State , 274 Ga. 327, 335, 554

——————

4 New York executed William Kemmler on August 6, 1890. According to the New York Times, “[p]robably no convicted murderer of modern times has been made to suffer as Kemmler suffered.” Far Worse Than Hanging, N. Y. Times, Aug. 7, 1890, p. 1. Witnesses recounted the execution:

“After the first convulsion there was not the slightest movement of Kemmler’s body. . . . Then the eyes that had been momentarily turned from Kemmler’s body returned to it and gazed with horror on what they saw. The men rose from their chai rs impulsively and groaned at the agony they felt. ‘Great God! [H]e is alive!’ [S]omeone said[.] ‘Turn on the current,’ said another . . . .

“Again came that click as before, and again the body of the uncon

scious wretch in the chair became as rigid as one of bronze. It was awful, and the witnesses were so ho rrified by the ghastly sight that they could not take their eyes off it. The dynamo did not seem to run smoothly. The current could be heard sharply snapping. Blood began to appear on the face of the wretch in the chair. It stood on the face like
sweat. . . .

“An awful odor began to permeate the death chamber, and then, as though to cap the climax of this fear ful sight, it was seen that the hair under and around the electrode on the head and the flesh under and around the electrode at the base of the spine was singeing. The stench was unbearable.” Ibid. (paragraph break omitted).

5 After a particularly gruesome elec trocution in Florida, this Court granted certiorari on the question whether electrocution creates a15 Cite as: 580 U. S. ____ (2017)

S. E. 2d 137, 144 (2001) (“[W]e hold that death by electro

cution, with its specter of excruciating pain and its cer

tainty of cooked brains and blistered bodies, violates the prohibition against cruel and unusual punishment”). The States then tried lethal gas. Although the gas chamber was initially believed to produce relatively pain

less death, it ultimately became clear that it exacted “exquisitely painful” sensatio ns of “anxiety, panic, [and] terror,” leading courts to declare it unconstitutional. See, e.g., Fierro v. Gomez , 77 F. 3d 301, 308 (CA9 1996) (inter

nal quotation marks omitted). 6 Finally, States turned to a “more humane and palata

ble” method of execution: lethal injection. Denno, 63 Ohio St. L. J.

, at 92. Texas performed the first lethal injection in 1982 and, impressed with the apparent ease of the process, other States quickly followed suit. S. Banner, The Death Penalty: An American History 297 (2002). One prison chaplain marveled: “ ‘It’s extremely sanitary. . . . The guy just goes to sleep. That’s all there is to it.’ ” Ibid

. What cruel irony that the method that appears most humane may turn out to be our most cruel experiment yet.

B Science and experience are now revealing that, at least with respect to midazolam-centered protocols, prisoners executed by lethal injection are suffering horrifying deaths beneath a “medically sterile aura of peace.” Denno, supra ,

Moore

, 528 U. S. 1133 (2000). See also Fla. Stat. Ann. §922.10 (West 2001).

6 This Court granted certiorari in Fierro , vacated the judgment, and remanded for consideration in light of the California Legislature’s adoption of lethal injection as the State’s primary method of execution. See Gomez v. Fierro , 519 U. S. 918 (1996).16 ARTHUR v. DUNN

at 66. Even if we sweep aside the scientific evidence, we should not blind ourselves to the mounting firsthand evidence that midazolam is simply unable to render pris

oners insensate to the pain of execution. The examples abound. After Ohio administered midazolam during the execu

tion of Dennis McGuire in January 2014, he “strained against the restraints around his body, and . . . repeatedly gasped for air, making snorting and choking sounds for about 10 minutes.” Johnson, Inmate’s Death Called ‘Hor

rific’, Columbus Dispatch, Jan. 17, 2014, pp. A1, A10. The scene was much the same during Oklahoma’s execution of Clayton Lockett in April 2014. After execu

When Arizona executed Joseph Rudolph Wood in July 2014 using a midazolam-based protocol, he “gulped like a fish on land.” Kiefer, Botched Execution, Arizona Dis

Following the dose of midazolam, Smith “clenched his fist” and was “apparently struggling for breath as he heaved and coughed for about 13 minutes.” Berman & Barnes, Alabama Inmate was Heaving, Cough

belies any suggestion that midazolam reliably renders prisoners entirely unconscious to the searing pain of the latter two drugs. These accounts are especially terrifying considering that each of these men received doses of pow

erful paralytic agents, which likely masked the full extent of their pain. Like a hangman’s poorly tied noose or a malfunctioning electric chair, midazolam might render our latest method of execution too much for our conscience— and the Constitution—to bear.

C As an alternative to death by midazolam, Thomas Ar

thur has proposed death by firing squad. Some might find this choice regressive, but the available evidence suggests “that a competently performed shooting may cause nearly instant death.” Denno, Is Electrocution An Unconstitu

tional Method of Execution? The Engineering of Death Over the Century, 35 Wm. & Mary L. Rev. 551, 688 (1994). In addition to being near instant, death by shoot

ing may also be comparatively painless. See Banner,

supra, at 203. And historically, the firing squad has yielded significantly fewer botched executions. See A. Sarat, Gruesome Spectacles: Botched Executions and America’s Death Penalty, App. A, p. 177 (2014) (calculat

ing that while 7.12% of the 1,054 executions by lethal injection between 1900 and 2010 were “botched,” none of the 34 executions by firing squad had been). Chief Justice Warren famously wrote that “[t]he basic concept underlying the Eighth Amendment is nothing less than the dignity of man.” Trop , 356 U. S., at 100 (plural

cols with a view toward protecting their own dignity, but they should not be permitted to shield the true horror of executions from official and public view. Condemned prisoners, like Arthur, might find more dignity in an instantaneous death rather than prolonged torture on a18 ARTHUR v. DUNN

medical gurney. To be clear, this is not a matter of permitting inmates to choose the manner of death that best suits their desires. It is a matter of permitting a death row inmate to make the showing Glossip requires in order to prove that the Constitution demands something less cruel and less unu

sual than what the State has offered. Having met the challenge set forth in Glossip , Arthur deserves the oppor

tunity to have his claim fairly reviewed in court. The Eleventh Circuit denied him this opportunity, and in doing so, thwarted the Court’s decision in Glossip , as well as basic constitutional principles.

* * * Twice in recent years, this Court has observed that it “has never invalidated a State’s chosen procedure for carrying out a sentence of death as the infliction of cruel and unusual punishment.” Baze , 553 U. S., at 48 (plurality opinion); Glossip , 576 U. S., at ___ (slip op., at 3) (same). In Glossip , the majority opinion remarked that the Court “did not retreat” from this nonintervention strategy even after Louisiana strapped a 17-ye ar-old boy to its electric chair and, having failed to kill him the first time, argued for a second try—which th is Court permitted. Id ., at ___– ___ (slip op., at 3–4). We should not be proud of this history. Nor should we rely on it to excuse our current inaction. I dissent.
