                            for the Middle District of Alabama
                              ________________________

                                         (March 21, 2012)
Before BARKETT, HULL and WILSON, Circuit Judges.

PER CURIAM:

       Thomas D. Arthur, an Alabama state prisoner sentenced to death, appeals

the dismissal of his 42 U.S.C. § 1983 complaint alleging that Alabama’s method

of executing inmates by lethal injection violates the Eighth and Fourteenth

Amendments to the U.S. Constitution and the separation of powers required by

Article III of the Alabama Constitution. Arthur’s execution is currently scheduled

to take place on March 29, 2012.

       Arthur instituted this challenge1 to Alabama’s lethal injection procedure

when Alabama announced in 2011 that it would switch from using sodium

thiopental to pentobarbital as the first of the three drugs in its lethal injection

protocol. Arthur alleges that pentobarbital takes substantially longer to render an

inmate fully insensate than sodium thiopental and, as a result of this delayed

effect, there is a significant risk that Alabama administers the second and third

drugs in its lethal injection procedure before pentobarbital has taken effect.


       1
          This is not Arthur’s first appeal with our Court. The factual and procedural history of
his challenges to his conviction and death sentence in the federal courts is recounted in our prior
decisions. See Arthur v. Allen, 

 (11th Cir.), modified on reh’g, 

(11th Cir. 2006); Arthur v. Allen, 248 Fed. Appx. 128 (11th Cir. 2007); Arthur v. King, 

 (11th Cir. 2007); Arthur v. Ala. Dept. of Corr., 285 Fed. Appx. 705 (11th Cir. 2008).



                                                 2
Arthur contends that this deficiency in Alabama’s practice of carrying out lethal

injections violates his right to be free from cruel and unusual punishment

protected by the Eighth Amendment of the U.S. Constitution.

      Arthur also alleges that (1) the prison personnel charged with carrying out

lethal injections in Alabama fail to follow regular procedures in carrying out lethal

injections, in violation of the Equal Protection Clause of the U.S. Constitution; (2)

Alabama’s policy of keeping information about its lethal injection procedure

secret violates the Due Process Clause of the U.S. Constitution; and (3) Alabama’s

lethal injection policies violate the Alabama Constitution by impermissibly

delegating lawmaking authority to prison officials.

      Alabama moved to dismiss the complaint. The district court dismissed the

Eighth Amendment and Due Process claims on statute of limitations grounds and

the Equal Protection claim for failing to state a claim upon which relief can be

granted. Having dismissed all of Arthur’s federal claims, the district court

declined to exercise supplemental jurisdiction over the state law claim. Arthur

appeals the dismissal of all four of his claims.

      A.     Eighth Amendment Violation

      The district court dismissed Arthur’s Eighth Amendment claim on the

ground that this claim was barred by Alabama’s two-year statute of limitations.

                                           3
See Powell v. Thomas, 

, 1303 (11th Cir. 2011) (“The two-year

limitations period . . . applies to section 1983 actions in Alabama.”) (internal

quotation marks omitted). In order to defeat Alabama’s statute of limitations

defense, Arthur must show that he filed his § 1983 complaint within two years of a

significant change in Alabama’s method of administering lethal injections. See

McNair v. Allen, 

, 1177 (11th Cir. 2008).2 Arthur contends that he

sufficiently alleged that the substitution of pentobarbital in Alabama’s execution

protocol gives rise to an impermissible risk that an inmate will be subject to

substantial pain because the second and third drugs in the protocol will be

administered prematurely. He argues that the district court erred in dismissing his

complaint without considering the evidentiary basis of his claim that, in fact, a

significant change has occurred in Alabama.

       Whether a significant change has occurred in a state’s method of execution

is a fact-dependent inquiry, which we have treated as such in each of our recent

cases addressing the lethal injection protocols of Alabama, Georgia and Florida.

Although we concluded in Powell v. Thomas, 

 (11th Cir. 2011),



       2
        Arthur first became subject to lethal injection as a method of execution in Alabama in
July 2002. Arthur initiated this action in June, 2011, two months after Alabama announced that it
would be substituting pentobarbital for sodium thiopental in its three-drug lethal injection
procedure.

                                                4
DeYoung v. Owens, 

 (11th Cir. 2011) and Valle v. Singer, 

, 1226 (11th Cir. 2011), that the replacement of sodium thiopental with

pentobarbital did not constitute a “significant change” in the lethal injection

execution protocol, each of these decisions is premised on the specific factual

allegations and/or evidence presented and considered in each of those cases. None

of the previous courts that were asked to decide whether the substitution of

pentobarbital for sodium thiopental is a “significant change” in the lethal injection

protocol could have resolved, nor did they resolve, that claim without considering

the facts and evidence. Simply because no court, based on the allegations and

evidence that has been presented in cases to date, has found a significant change

does not mean that such evidence does not exist. To read our circuit decisions in

Powell, DeYoung, and Valle as holding—no matter what new facts allege or new

evidence reveals—that Alabama’s, Georgia’s and Florida’s substitutions of

pentobarbital for sodium thiopental is not a significant change in their execution

protocols is to ignore the reality that scientific and medical evidence that exists

today may differ from that which new scientific and medical discoveries and

research reveal tomorrow.

      Specifically, we held in Powell (Williams) v. Thomas that, based on the

district court’s review of the evidence and factual findings after a hearing on a

                                           5
death row inmate’s motion to stay his execution, “the evidence present” did not

demonstrate a “substantial likelihood of success on the merits” of the inmate’s

Eighth Amendment challenge. 

, 1257 (11th Cir. 2011). We did so

only after determining that the district court had not “abused its discretion” by

deciding to credit an expert report submitted by Alabama, id., and only with the

benefit of the district court’s finding “that the State’s representations about the

amended execution protocol were accurate.” Id. at 1258. Next, in Powell, we

reviewed a complaint presenting identical allegations and relying on the same

expert testimony and exhibits as were rejected in Powell (Williams), and we

affirmed the dismissal of the complaint because its allegations and supporting

evidence were indistinguishable from those in Powell (Williams). 643 F.3d at

1302 (noting that Powell’s complaint was “nearly identical” to the one filed in

Powell (Williams)); id. at 1303 (reviewing evidence relied on by both Williams

and Powell). And in DeYoung and Valle, we affirmed the denial of death-row

inmates’ motions to stay their executions with the benefit of extensive fact-finding

made by the district court at evidentiary hearings conducted in both cases. See

646 F.3d at 1323 (reviewing district court’s factual findings); 655 F.3d at 1226

(adopting district court’s opinion considering evidence presented at a hearing on a

motion for stay of execution).

                                           6
       The district court in Arthur’s case, however, never considered Arthur’s

evidence in support of his allegations that there has been a “significant change” to

Alabama’s execution protocol, instead summarily concluding that his Eighth

Amendment claim was barred by the statute of limitations.3 Thus, unlike each of

our recent precedents dismissing inmates’ § 1983 lethal injection execution

claims, we have no evidentiary basis whatsoever on which to conclude whether, as

Arthur alleges, a “substantial change” in Alabama’s administration of its execution

protocol has occurred. McNair, 515 F.3d at 1177. There has been no finding

about the manner in which Alabama administers its lethal injections, no evaluation

of whether Alabama’s representations are accurate, and no opportunity whatsoever

to contradict the State’s assertions with Arthur’s own evidence. And the lack of

factual development in this record is only exacerbated by Alabama’s policy of

maintaining secrecy surrounding every aspect of its three-drug execution method.



       3
          The dissent asserts that “the interpretation and application of a statute of limitations is a
question of law.” However, that our review of the district court’s application of a statute of
limitations is de novo, is a distinct question from whether a particular statute of limitations
involves questions of fact that the district court must determine in the first instance. See e.g.,
Kearse v. Sec’y, Fla. Dep’t of Corr., ___ F.3d. ___, 

 (11th Cir. 2011)
(remanding to the district court to determine in the first instance whether federal habeas
petitioner’s state petition was “properly filed” in order to satisfy the one-year statute of
limitations for filing a federal habeas petition under 28 U.S.C. § 2244(d)(2)); Tello v. Dean
Witter Reynolds, Inc., 

 (11th Cir. 2005) (remanding to the district court for the
factual development of the question of “inquiry notice” necessary to the resolution of the statute
of limitations question in securities fraud action).

                                                   7
       For several reasons, we conclude that Arthur’s Eighth Amendment

allegations are not so similar to those presented in our previous cases that his

complaint can be dismissed on a Rule 12(b)(6) motion. See Anders v. Hometown

Mortg. Svcs., 

, 1031 (11th Cir. 2003) (holding that disposition of a

previous case may bind a subsequent decision only when the “facts and

circumstances [are] sufficiently similar to those under which [the previous

decision] arose.”). In DeYoung, we concluded that the evidence presented at an

evidentiary hearing showed that no substantial change had occurred in Georgia’s

method of execution within two years of the filing of the plaintiff’s complaint in

2011. 646 F.3d at 1325 (concluding that the evidence presented did not show a

substantial change and proceeding to review this evidence). However, that

Georgia’s method of execution may not have undergone a substantial change in

the relevant time period has no bearing on the factual question of whether a

substantial change has occurred in the way that Alabama administers its method of

execution, as Arthur’s complaint alleges.4

       Our holdings in Powell and Powell (Williams), unlike DeYoung, involved


       4
         Similarly, our conclusion in Valle that the plaintiff there had not shown a “substantial
likelihood of success on the merits” after an evidentiary hearing on his claim that Florida’s
administration of lethal injections violated the Eighth Amendment has no bearing on the factual
question of whether a substantial change has occurred in Alabama’s implementation of its
execution procedures. 655 F.3d at 1225.

                                                8
challenges to Alabama’s administration of lethal injections, however, Arthur’s

complaint and supporting affidavits are sufficiently different from the complaint

filed in both cases to survive dismissal at the pleadings stage. In particular,

Arthur’s complaint is supported by the affidavits of two expert witnesses who had

reviewed the testimony of Alabama’s expert witness and were prepared to rebut

that testimony. Both experts were prepared to testify about specific defects in

Alabama’s administration of its execution protocol, including deficiencies and

irregularities in Alabama’s procedure to determine whether an inmate is conscious

before injecting the second chemical in its three-drug execution procedure.

Moreover, at least one of these experts is prepared to present his conclusions

drawn from reviewing eyewitness accounts of the execution of Eddie Powell.

Because Eddie Powell and Jason Williams were the first Alabama inmates to be

executed using pentobarbital instead of sodium thiopental, Arthur’s complaint

marks the first time that an Alabama death-row inmate has been able to challenge

Alabama’s lethal injection procedure using evidence of how pentobarbital is

actually administered in Alabama. In contrast, the plaintiff’s expert in both Powell

and Powell (Williams) was unable to rely on any evidence of how Alabama

actually administers its execution protocol; in fact, the expert’s testimony in both

of those cases was drawn from observations of executions conducted in Oklahoma

                                          9
rather than in Alabama, and contained no criticism or objection to the manner in

which Alabama administers lethal injections or to any expert testimony set out by

Alabama in defense of its executions.5

       These significant differences between the factual allegations and supporting

affidavits in this case, which we must assume to be true at the motion to dismiss

stage, render Arthur’s case distinct from the facts and circumstances addressed in

our previous decisions. See Anders, 346 F.3d at 1031. Accordingly, the district

court committed reversible error in dismissing Arthur’s Eighth Amendment claim

without any opportunity for factual development, including discovery between the

parties.

       B. Equal Protection Violation

       Arthur next alleges that Alabama’s material deviation from its lethal

injection protocol, namely that it did not conduct the pinch test for consciousness


       5
          Alabama claims that a footnote in the district court’s opinion referring to Arthur’s
eyewitness and expert affidavits are sufficient to provide the factual development that we have
relied upon in our previous cases. However, Alabama’s contention is meritless because none of
the district court’s remarks in the footnote come close to resembling a finding of fact about, for
example, the credibility of Arthur’s witnesses to the Powell execution, or the persuasiveness of
the analysis presented by Arthur’s experts in contrast to the analysis presented by Alabama. Nor
does the footnote make any findings as to whether, as both of Arthur’s experts describe in their
reports, and as one of Arthur’s supportive eyewitness affidavits testifies, the individuals
conducting the execution failed to administer a “pinch test” in order to determine whether Eddie
Powell was insensate before injecting the second and third drugs. Thus, we cannot agree with
Alabama’s contention that this footnote provides sufficient factual development to stand in lieu
of discovery and a hearing on Arthur’s evidence.

                                                10
in the execution of Eddie Powell, violates his right to Equal Protection under the

Fourteenth Amendment, by burdening his right to be free from cruel and unusual

punishment. The district court dismissed this claim as too speculative.

      To state an Equal Protection claim, Arthur first has to “show that the State

will treat him disparately from other similarly situated persons,” DeYoung, 646

F.3d at 1327. Second, “[i]f a law treats individuals differently on the basis of . . .

[a] suspect classification, or if the law impinges on a fundamental right, it is

subject to strict scrutiny.” Leib v. Hillsborough County Pub. Transp. Comm’n,

, 1306 (11th Cir. 2009). Otherwise, Arthur must “must show that

the disparate treatment is not rationally related to a legitimate government

interest.” DeYoung, 646 F.3d at 1327-28.

      To survive a motion to dismiss, Arthur has to plead “only enough facts to

state a claim to relief that is plausible on its face.” Bell Atlantic v. Twombly, 

, 570 (2007). Here, Arthur has alleged enough facts to constitute a

plausible Equal Protection claim because he alleges that Alabama has substantially

deviated from its execution protocol in a manner that significantly reduces inmate

safeguards. He alleges that Alabama’s lethal injection protocol requires pinching




                                           11
the inmate as the last consciousness check6 after the initial injection of

pentobarbital and prior to injecting the final two lethal drugs. The consciousness

check is performed to reduce or eliminate the risk of excruciating pain that would

follow the injection of the second and third drugs in the lethal injection protocol.

Arthur alleges that based on eyewitness testimony, the State of Alabama failed to

perform the pinch test during the 2011 execution of Eddie Powell, even though

Powell’s eyes remained open, his head turned from side to side, and he clenched

his jaws.

       Arthur alleges that Alabama’s reduction in safeguards burdens his right to

be free from cruel and unusual punishment. “[S]ubjecting individuals to a risk of

future harm—not simply actually inflicting pain—can qualify as cruel and unusual

punishment.” Baze v. Rees, 

, 49 (2008). Significant deviations from a

protocol that protects inmates from cruel and unusual punishment can violate the

Eighth Amendment. Indeed, the Sixth Circuit recently affirmed an order to stay an

execution because four core deviations from Ohio’s lethal injection protocol,

including foregoing mandated vein assessments, burdened the Equal Protection

rights of inmates in Ohio. See In re Ohio Execution Protocol Litigation, No.


       6
          As alleged, Alabama assesses an inmate’s consciousness through graded stimuli, first
calling the inmate’s name, then stroking the inmate’s eyelids and finally pinching the inmate’s
arm.

                                               12
12–3035 (6th Cir. Jan. 13, 2012), affirming, Cooey v. Kasich, 

, 643-644 (S.D. Ohio 2011) (“We agree with the district court that the State

should do what it agreed to do: in other words it should adhere to the execution

protocol it adopted.”).

       Here, Arthur alleges that Alabama failed to perform a required

consciousness check in a recent execution, a significant deviation from its

execution protocol. In light of Arthur’s other allegations regarding the veil of

secrecy that surrounds Alabama’s execution protocol, it is certainly not

speculative and indeed plausible that Alabama will disparately treat Arthur

because the protocol is not certain and could be unexpectedly changed for his

execution.7

       Accordingly, accepting Arthur’s allegations as we must at the motion to

dismiss stage, we conclude that the district court erred in dismissing Arthur’s

Equal Protection claim at this stage of the proceedings and remand for further

factual development.8


       7
         Arthur argues that it is necessary for his Equal Protection and Due Process claims that
Alabama make available a copy of its written execution protocol. We leave it to the district court
to determine if production of Alabama’s written execution protocol is necessary to resolve
Arthur’s claims.
       8
         In order to give the district court the opportunity to conduct any additional proceedings
prior to Arthur's presently scheduled execution date of March 29, 2012, we are returning
jurisdiction of this matter to the district court forthwith with instructions to conduct any

                                                13
       REVERSED and REMANDED WITH INSTRUCTIONS.




additional proceedings, including an evidentiary hearing, as the district court deems necessary.

                                                14
HULL, Circuit Judge, dissenting:

      I respectfully dissent because the majority opinion fails to follow our

binding precedent about the substitution of the first drug pentobarbital for sodium

thiopental in Alabama’s three-drug lethal injection protocol. Based on this

circuit’s binding precedent, as outlined below, the district court concluded that (1)

Arthur’s § 1983 claims based on the Eighth Amendment and Due Process were

barred by the statute of limitations because the April 2011 substitution of

pentobarbital for sodium thiopental is not a significant alteration in the 2002 lethal

injection protocol so as to restart the statute of limitations clock, and (2) Arthur’s

Equal Protection claim failed to state a claim.

      For the reasons that follow, I would affirm the district court’s dismissal of

the plaintiff’s complaint. I recount in detail the nature of Arthur’s § 1983 claims

about pentobarbital and compare them with our § 1983 precedent holding not once

but three times that the substitution of pentobarbital does not restart the statute of

limitations clock. This comparison shows that Arthur makes the same

pentobarbital claims as other inmates have before and our precedent controls

Arthur’s claims and requires dismissal.

                          I. PROCEDURAL HISTORY

      This is Arthur’s fifth § 1983 civil action since he was sentenced to death in

1992, and his third such § 1983 challenge to lethal injection as his method of
execution. I review his two earlier § 1983 method-of-execution challenges and

then this one.

A.    Arthur’s Prior § 1983 Challenges to Lethal Injection Protocol

      On May 14, 2007, twenty-seven days after the State filed a motion to set

Arthur’s execution date, Arthur filed a § 1983 action alleging that “Alabama’s

three-drug lethal injection protocol . . . violat[ed] the Eighth Amendment’s

prohibition against cruel and unusual punishment” and seeking injunctive relief

“to prevent Alabama’s use of the lethal injection procedure.” Arthur v. Allen, No.

07-13929, 248 F. App’x. 128, 130 (11th Cir. Sept. 17, 2007) (unpublished). The

district court granted the State’s motion to dismiss the case based on laches. Id. at

129. This Court affirmed, concluding that the district court did not abuse its

discretion in determining that Arthur had unnecessarily delayed filing his

challenge to Alabama’s lethal injection procedure, given that Arthur was on notice

since at least mid-2006 that a § 1983 challenge to Alabama’s method of execution

was available. Id. at 131-32.

      On October 9, 2007, Arthur filed a second § 1983 challenge to Alabama’s

lethal injection protocol, which the district court again dismissed for unreasonable

delay. See Arthur v. Ala. Dep’t of Corr., No. 07-15877, 285 F. App’x. 705, 705

(11th Cir. July 29, 2008) (unpublished). On appeal, Arthur argued that his second

                                         16
method-of-execution challenge was distinguishable from his first because

Alabama had made material changes to its lethal injection protocol in October

2007. Id. This Court rejected that argument and affirmed the dismissal of

Arthur’s second § 1983 challenge to Alabama’s lethal injection protocol, noting

“that it does not appear that Alabama’s 26 October 2007 minimal changes to its

execution protocol materially changed the procedures that were adopted in 2002.”

Id.1 We concluded that “Arthur’s challenge that Alabama’s revised execution

protocol constitutes cruel and unusual punishment is the same challenge that he

raised [before],” and thus the district court “did not abuse its discretion in

dismissing for unreasonable delay.” Id.

B.     Arthur’s Present § 1983 Complaint

       On April 26, 2011, the Alabama Department of Corrections (“ADOC”)

amended its lethal injection protocol to substitute the administration of

pentobarbital for sodium thiopental as the first drug in the three-drug protocol. On

June 8, 2011, Arthur filed the present § 1983 action.2 Arthur’s complaint, as



       1
        In 2007, Alabama’s protocol was modified to add an additional procedural safeguard,
namely, a consciousness assessment after the administration of the first drug. See Arthur v.
Allen, 

 (S.D. Ala. 2007).
       2
        Arthur’s two previous § 1983 challenges to the lethal injection protocol were filed in the
United States District Court for the Southern District of Alabama. The present case was filed in
the United States District Court for the Middle District of Alabama.

                                                17
amended, raised three § 1983 claims: (1) Eighth Amendment: the ADOC’s use of

pentobarbital as the first drug in its three-drug lethal injection protocol violates the

Eighth Amendment’s ban on cruel and unusual punishment; (2) Due Process: the

ADOC’s secrecy in adopting and revising its lethal injection protocol violates the

Fourteenth Amendment’s Due Process Clause; and (3) Equal Protection: the

ADOC has materially deviated from its lethal injection protocol (as shown by

evidence that witnesses to the State’s recent execution of Eddie Powell did not

observe officials pinch Powell’s arm before administration of the second drug),

thereby violating Arthur’s rights under the Fourteenth Amendment’s Equal

Protection Clause.3

C.     Three Expert Declarations and 23 Other Exhibits Attached to Arthur’s
       Complaint

       Arthur attached to his complaint not only the declarations of three expert

witnesses, but also voluminous documentary evidence. Arthur references these

declarations and exhibits repeatedly as part of his complaint and asks this Court to

consider them as part of his pleaded allegations in his complaint. See Griffin

Industries, Inc. v. Irvin, 

, 1205 (11th Cir. 2007) (considering


       3
         Arthur’s complaint also contained a state-law claim that Alabama’s lethal injection
statute violates the Alabama Constitution’s doctrine of separation of powers. Because it
dismissed the federal § 1983 claims, the district court declined to exercise supplemental
jurisdiction over this state law claim.

considered part of the pleadings for all purposes, including a Rule 12(b)(6)

motion”); see also Brooks v. Blue Cross & Blue Shield of Fla., Inc., 

, 1369 (11th Cir. 1997) (“[W]here the plaintiff refers to certain documents in

the complaint and those documents are central to the plaintiff’s claim, then the

Court may consider the documents part of the pleading for purposes of Rule

12(b)(6) dismissal, and the defendant’s attaching such documents to the motion to

dismiss will not require conversion of the motion into a motion for summary

judgment.”). Accordingly, Arthur has already presented voluminous evidence

which is considered for purposes of the motion to dismiss.

      Anesthesiologist Dr. David Lubarsky’s declaration (attached to Arthur’s

complaint) first describes Alabama’s protocol: Alabama’s lethal injection protocol

                                         19
calls for the serial injection of 2,500 mg of pentobarbital (which, like sodium

thiopental, is intended to render the inmate unconscious and insensate), then 50

mg of pancuronium bromide (which paralyzes voluntary muscles), and then 120

mEq of potassium chloride (which stops the heart). Dr. Lubarsky states that if the

first drug (now pentobarbital) fails to establish and maintain loss of consciousness

and sensation, the inmate will suffer excruciating pain, which will be masked by

the paralytic pancuronium bromide. Notably, Dr. Lubarsky never states that 2,500

mg of pentobarbital will not cause unconsciousness in humans. Rather, Dr.

Lubarsky focuses on the lack of data about large doses of pentobarbital in humans.

Dr. Lubarsky states: (1) pentobarbital “is designed to produce sedation, not

anesthesia,” it “is not approved by the FDA as an anesthesia induction agent,” and

“there is no scientific literature establishing the anesthetic dose of pentobarbital”;4

(2) pentobarbital does have “an off-label use . . . for induction of barbiturate coma

in severe brain injury patients, [but] this use involves slow administration of the

drug over several hours”; (3) “[p]entobarbital acts much more slowly as a sedative

than sodium thiopental works as an anesthetic”; (4) “[s]odium thiopental can


       4
        Dr. Lubarsky’s declaration states that pentobarbital is used for animal euthanasia. In
animal euthanasia, pentobarbital is typically administered in a dosage of “up to 100mg . . . per
kilogram of body weight in a variety of species,” which would equate to 7,500 mg for an animal
of about 165 pounds. In animal euthanasia, pentobarbital is used alone to cause death, not simply
to render the animal unconscious and insensate before administration of other drugs.

                                               20
achieve its maximum effect within sixty seconds,” whereas “[t]he comparable

figure for pentobarbital is fifteen to sixty minutes” for maximum effect;5 (5)

“[t]here is no data at all about the onset time of large boluses (doses of a drug

given intravenously) of pentobarbital in humans”; (6) “[p]entobarbital has been

tested in humans only at doses much lower than the one specified in Alabama’s

lethal injection protocol, and administered slowly”; (7) “[t]here is no data in

humans at all about the impact of large doses [of pentobarbital] and acute

tolerance”; (8) the package insert for pentobarbital states, “There is no average

intravenous dose of [pentobarbital] that can be relied on to produce similar effects

in different patients” and, based on that insert, a 2,500 mg dose “is insufficient to

assure that an inmate is unconscious when given pancuronium bromide and

potassium chloride.”

       The essence of Dr. Lubarsky’s testimony is that he does not know what

levels of pentobarbital will anesthetize humans because he has never used it on

humans and there is no study telling him. The most he can say is he believes that

2,500 mg is insufficient “to assure” or guarantee unconsciousness. In any event,

       5
         Dr. Lubarsky does not define or explain “maximum effect.” Importantly, Dr. Lubarsky
never opines that it would take fifteen to sixty minutes to render an inmate unconscious if
pentobarbital was used. The amount of time it takes for pentobarbital to reach “maximum effect”
is not the issue. Rather, the issue is only whether pentobarbital (such as in the 2,500 mg dose
here) will timely cause an inmate to reach unconsciousness before administration of the second
drug.

                                              21
Dr. Lubarsky never refutes the statement in the affidavit from Dr. Dershwitz (also

submitted by Arthur and attached to Arthur’s complaint) that 2,500 mg of

pentobarbital causes unconsciousness and lack of sensation.

      Anesthesiologist Dr. Mark Heath’s declaration (also attached to Arthur’s

complaint) has a similar focus on the lack of data and knowledge about the length

of time for pentobarbital to induce unconsciousness. Dr. Heath states: (1) “[t]he

chemical properties of pentobarbital strongly suggest that it would produce a more

gradual and prolonged transition from consciousness to unconsciousness than

would thiopental”; (2) Dr. Heath was “unaware of a single instance of the use of

pentobarbital in the clinical setting to induce anesthesia or unconsciousness in a

conscious person”; (3) there is “no body of clinical knowledge regarding the

behavior of pentobarbital and its effects on human beings when rapidly

administered in high dosages to a conscious person”; (4) “[t]he switch to

pentobarbital, for which there is no clinical knowledge regarding its effects on

human beings when rapidly administered in high dosages to a conscious person,

combined with the use of pancuronium bromide and potassium chloride, confers a

substantial risk of an excruciating and agonizing death process”; (5) pentobarbital

“is classified as an intermediate-acting barbiturate,” whereas sodium thiopental “is

classified as an ultrashort-acting and/or ultrafast-acting barbiturate”; and (6) “by

                                          22
dint of its being in a different class of barbiturates, pentobarbital would be slower

in producing sedation and unconsciousness than would thiopental.” Dr. Heath

opined that, based on witness accounts of the executions of Eddie Powell and Roy

Blankenship, “the pentobarbital did not produce . . . rapid and smooth transition

from consciousness to unconsciousness,” though Dr. Heath was “not able to

identify the cause of the unexpected effects of pentobarbital” in those executions.

Yet, like Dr. Lubarsky, Dr. Heath never states that a 2,500 mg dose of

pentobarbital does not cause unconsciousness in humans. Dr. Heath, like Dr.

Lubarsky, also never states how long a 2,500 mg dose will take to cause loss of

consciousness.

       Significantly, Arthur’s complaint also attached and repeatedly referenced

the expert report of anesthesiologist and pharmacologist Dr. Mark Dershwitz.6 Dr.

Dershwitz is familiar with pentobarbital as an anesthetic and expressly opines that

pentobarbital, when administered to a human, will induce and cause an adequate

depth of anesthesia and loss of consciousness. Dr. Dershwitz’s report stated: (1)

pentobarbital “is classified as an intermediate-acting barbiturate”; (2)

pentobarbital is commonly used for general anesthesia in laboratory animals; (3)


       6
         Dr. Dershwitz has both an M.D. and a Ph.D. in pharmacology. The State filed Dr.
Dershwitz’s report in another inmate’s case, but Arthur has now filed it in this case as part of the
allegations in his complaint.

                                                 23
pentobarbital “is not used for general anesthesia in humans because its duration is

considered too long for this purpose,” since in almost all clinical anesthesia cases,

“the goal is to have the patient awaken quickly and recover promptly following

completion of the surgical procedure” and the “duration of pentobarbital, when

administered in doses sufficient to cause unconsciousness, is too long to achieve

these goals”; (4) pentobarbital is used clinically to induce and maintain a

barbiturate coma following brain injury, and for this purpose in an average 80 kg

(about 175 lb) adult would be 800 mg given over 30 minutes, then a continual

infusion of about 400 mg every three hours; (5) pentobarbital, when used for

barbiturate coma, results in the cessation of breathing, so the patient is

mechanically ventilated; (6) for barbiturate coma induction and maintenance in an

80 kg adult, “it would take about 5 – 10 hr to achieve the administration of 2,500

mg of pentobarbital,” since the 800 mg/400 mg per 3 hr dosage is enough to

sustain the coma and “more rapid administration of pentobarbital causes severe

and dangerous decreases in blood pressure that might be fatal to the patient”; (7)

the 2,500 mg dose of pentobarbital in Alabama’s lethal injection protocol is “far in

excess of that used to induce and maintain barbiturate coma . . . [and causes] a

depth of anesthesia far greater than that needed for any surgical procedure,” and

thus “once 2,500 mg of pentobarbital have been administered intravenously to an

                                          24
inmate, there is an exceedingly small risk that the inmate could experience the

effects of the subsequently administered pancuronium bromide or potassium

chloride”; (8) a 2,500 mg dose of pentobarbital “will cause virtually all persons to

stop breathing” and “will cause the blood pressure to decrease to such a degree

that perfusion of blood to organs will cease or decline such that it is inadequate to

sustain life”; (9) “virtually every person given 2,500 mg of pentobarbital will have

stopped breathing prior to the administration of pancuronium bromide” and thus,

even in the absence of the other two drugs, “the administration of 2,500 mg of

pentobarbital by itself would cause death to almost everyone”; and (10)

“[p]entobarbital is the most common agent used for physician-assisted suicide in

those jurisdictions where the practice is legal.”

      Arthur also attached to his complaint several newspaper accounts and

witness affidavits of the execution of Alabama inmate Eddie Powell. Together

these accounts indicate that after the chaplain stopped praying and after the

administration of pentobarbital began, Powell raised his neck and head off the

gurney, opened his eyes and looked confused, clenched his teeth and flexed his

neck muscles. But then, by all accounts, Powell laid his head back down and did

not move again.

      In fact, according to the affidavit of Powell’s own attorney, Christine

                                          25
Freeman (attached to Arthur’s complaint), after Powell laid his head back down, a

corrections officer called Powell’s name and touched Powell’s face, then stepped

back against the wall of the room, after which the observers “all remained seated,

for quite a while longer.” The affidavit of Matt Schulz, Powell’s other attorney

(also attached to Arthur’s complaint), states that: “A few minutes after Mr.

Powell’s head had gone back down, a guard approached Mr. Powell, and called

out loudly to him: ‘Eddie. Eddie. Eddie.’ Mr. Powell made no response. The

guard then ran his finger lightly over Mr. Powell’s left eyelash. Again, there was

no response.”7

       Also attached to Arthur’s complaint is an Associated Press newspaper

article by Greg Bluestein about the Georgia execution (using pentobarbital) of Roy

Blankenship. The Bluestein article stated, among other things, that “Blankenship

       7
         While I focus on the affidavits filed as part of Arthur’s complaint, I note that the State
also filed affidavits. Arthur never moved to strike any of the State’s affidavits. The witness
affidavit of Anne Hill, the ADOC’s General Counsel, confirmed that an execution team member
“conducted a consciousness assessment using graded stimulation—saying Powell’s name,
stroking his eyelashes and pinching the back of his left arm.” Powell did not respond to any
stimuli performed during the consciousness check. Hill states that she sat in the Commissioner’s
viewing room directly in front of Powell and “could see very well everything occurring in the
execution chamber, prior to and during the execution.” In another affidavit, Warden Patterson
states that the three types of consciousness checks were done, Powell’s execution took place in
compliance with Alabama’s lethal injection protocol, and Warden Patterson observed no
deviation whatsoever.
         Although I recount the State’s affidavits, I do not rely on any of the State’s evidence for
my analysis of the correctness of the district court’s Rule 12(b)(6) dismissal of Arthur’s
complaint. And, as noted, Arthur’s affidavits agree that Powell had stopped moving by the time
the two consciousness checks were performed and Powell did not respond to them.

jerked his head several times, mumbled inaudibly and appeared to gasp for breath

for several minutes after he was pumped with pentobarbital.” By all accounts,

Blankenship then “became still and was unconscious before the second drug was

administered.” DeYoung v. Owens, 

, 1325–26 (11th Cir. 2011).

D.     Dismissal of Arthur’s Complaint

       On August 15, 2011, the State moved to dismiss Arthur’s complaint or,

alternatively, for summary judgment.8 The State argued, inter alia, that Arthur’s

complaint was barred by the statute of limitations and failed to state a claim upon

which relief could be granted.

       On November 3, 2011, the district court issued an order granting the State’s

motion to dismiss. The district court concluded that Arthur’s Eighth Amendment

and Due Process claims were barred by the statute of limitations. The district

court explained that: (1) a two-year statute of limitations governed Arthur’s



       8
         The State attached evidentiary materials to its motion, including a deposition transcript
from Dr. Dershwitz and affidavits from other witnesses to Powell’s execution that stated that the
full consciousness check was performed and Powell never appeared to be in pain.
        The district court did not rule on the State’s alternative summary judgment motion and
did not consider its attached evidentiary materials. I need not rely on any of the State’s evidence
because, as this is an appeal from the grant of a Rule 12(b)(6) motion to dismiss, I focus on
Arthur’s complaint and the attachments thereto.
        In any event, as discussed later, this Court has rejected claims that the evidence of the
Powell execution shows an Eighth Amendment violation given that Powell was unconscious
before the second drug was administered. See DeYoung v. Owens, 

, 1327 n.5
(11th Cir. 2011); see also Valle v. Singer, 

, 1232-33 & n.9 (11th Cir. 2011).

§ 1983 claims; (2) a method-of-execution claim accrues on the later of the date the

inmate’s state review is complete or the date on which the inmate becomes subject

to a new or substantially changed execution protocol; (3) Arthur’s claim accrued

on July 31, 2002, when Alabama adopted lethal injection as its method of

execution; (4) Eleventh Circuit precedent foreclosed Arthur’s arguments that the

switch from sodium thiopental to pentobarbital resulted in a new or substantially

changed execution protocol; (5) Eleventh Circuit precedent also established that

Arthur’s Due Process claim about the secrecy of Alabama’s protocol accrued on

July 31, 2002; and (6) thus, Arthur brought his Eighth Amendment and Due

Process claims nearly seven years after the limitations period expired.

       The district court dismissed Arthur’s Equal Protection claim as to the

ADOC’s alleged failure to conduct a full consciousness check during the Powell

execution for failure to state a claim. The district court reasoned that, even

“[a]ssuming that observation of the ‘pinch test’ is constitutionally significant,

Arthur’s allegation, that ADOC’s protocol was not followed in one execution,

does not raise his right to relief above a speculative level.”

       Arthur appealed.9

                                  II. OUR PRECEDENT

       This is not the first time this Court has been called upon to decide a § 1983

challenge to Alabama’s use of pentobarbital as the first drug in its three-drug

execution protocol. See Powell v. Thomas, 

 (11th Cir. May 19,

2011) (“Powell (Williams)”); Powell v. Thomas, 

 (11th Cir. June

15, 2011) (“Powell”).10 We have also decided similar § 1983 challenges to

Georgia’s and Florida’s contemporaneous decisions to use pentobarbital as the

first execution drug. See DeYoung, 

 (11th Cir. July 20, 2011);

Valle v. Singer, 

 (11th Cir. Sept. 7, 2011). I discuss these prior

cases in detail below in order to show how Arthur’s very claims about

pentobarbital—both factually and legally—were already rejected in these cases.

A.     Powell (Williams)

       Alabama announced its switch from sodium thiopental to pentobarbital a



2008). “We accept the allegations in the complaint as true and construe them in favor of the
plaintiff.” Id. “A Rule 12(b)(6) dismissal on statute of limitations grounds is appropriate only if
it is apparent from the face of the complaint that the claim is time-barred.” Id. (quotation marks
omitted). To state a claim for relief, a complaint must contain factual allegations that, if true,
would “raise a right to relief above the speculative level.” Speaker v. U.S. Dep’t of Health &
Human Servs. Ctrs. for Disease Control & Prevention, 

, 1380 (11th Cir. 2010)
(quoting Bell Atl. Corp. v. Twombly, 

, 555, 

, 1964-65 (2007)).
       10
        Powell (Williams) dealt with the claims of Alabama death row inmate Jason Williams,
who was permitted to intervene in a § 1983 case brought by fellow Alabama death row inmate
Eddie Powell. Powell was the separate appeal by Powell himself from the same district court
case.

                                                29
few weeks before Williams’s scheduled execution date. Powell (Williams), 641

F.3d at 1256. Williams moved to intervene in Powell’s ongoing § 1983 action and

moved the district court for a stay of execution. Id. Williams alleged, among

other things, “that the ADOC’s protocol change will result in a violation of

[Williams’s] Eighth Amendment right to be free from cruel and unusual

punishment.” Id. The district court granted Williams’s motion to intervene.

      Williams’s complaint alleged: (1) “the drug that ADOC now intends to use

as the first drug in the [lethal injection] sequence, pentobarbital, is not an ultra

short acting barbiturate like sodium thiopental”; (2) “[p]entobarbital is not an

agent used medically to induce loss of consciousness and loss of sensation because

of the extended length of time it takes for the drug to act”; (3) “[p]entobarbital is

less lipid soluble than sodium thiopental, decreasing the rate of penetration into

the brain, causing the slower onset of anesthesia after intravenous injection”; (4)

“[w]hile pentobarbital is used to create a state of sedation[,] sedation is not the

same as a loss of consciousness and loss of sensation. Sedated individuals can be

aware and can feel pain”; (5) “[i]f pentobarbital is ineffectively administered and

fails to establish and maintain loss of consciousness and loss of sensation, [the

second drug] pancuronium bromide serves only to mask the inmate’s pain and

suffering from observers, but does not prevent the inmate from suffering a painful

                                           30
death by asphyxiation”; (6) “[a]bsent complete anesthesia, the injection of [third

drug] potassium chloride causes excruciating pain”; (7) “there is no standard

clinical dose of pentobarbital used to induce anesthesia” because “pentobarbital is

not even used medically to induce [un]consciousness and loss of sensation”; and

(8) “the use of a drug not approved to induce anesthesia creates a substantial risk

of serious harm to Mr. Williams.” (Emphasis added.)

      In Powell (Williams), the district court outlined Alabama’s protocol as

having these steps—which are the same steps outlined in Dr. Lubarsky’s

declaration filed by Arthur himself:

      The protocol calls for the administration of three drugs in a specific
      sequence, beginning with either sodium thiopental, or in case of its
      unavailability, pentobarbitol, with an initial injection of 2.5 grams. A
      team member physically assesses the consciousness of the inmate after
      the initial injection, by applying graded stimulation. . . . After the inmate
      is documented to be unconscious, the second and third drugs are
      administered.

Powell v. Thomas, 

, 1277 (M.D. Ala. 2011) (footnotes

omitted).

      The district court also reviewed the parties’ evidence, including “(1) an

expert report, introduced by Williams, challenging the use of pentobarbital in

Oklahoma executions, and (2) an expert report, submitted by the State, asserting

that the use of pentobarbital in the Alabama lethal injection protocol presents ‘an

                                           31
exceedingly small risk that a condemned inmate . . . would experience any pain or

suffering associated with the administration of lethal doses of pancuronium

bromide and potassium chloride.’” Powell (Williams), 641 F.3d at 1257 (ellipsis in

original). This second expert report at issue in Powell (Williams) is by Dr.

Dershwitz, whose report Arthur actually filed and attached to his complaint. The

district court credited Dr. Dershwitz’s expert report and denied Williams’s motion

for a stay, concluding that Williams had not demonstrated a substantial likelihood

of success on the merits of his Eighth Amendment claim. Id.

      Williams appealed to this Court, arguing that the district court abused its

discretion in denying his motion for a stay of execution. Id. at 1256-57. This

Court reviewed the parties’ evidence and found that “[t]he evidence present[ed]

does not demonstrate that the ADOC’s use of pentobarbital creates [a] substantial

risk of serious harm to Williams.” Id. at 1257. Thus, this Court concluded, “We

are unable to determine that the district court abused its discretion by crediting the

expert report submitted by the State and concluding that Williams has not

demonstrated a substantial likelihood of success on the merits of this Eighth

Amendment claim.” Id. Here, because Arthur attaches Dr. Dershwitz’s report to

his complaint, we must accept it as true for purposes of the State’s motion to

dismiss, obviating any need for fact-finding or crediting by the district court.

                                          32
      Williams also alleged on appeal that he had “a broad Eighth Amendment

right to know the details of his execution.” Id. at 1258. This Court rejected that

argument, specifically holding that “[t]he replacement of sodium thiopental with

pentobarbital does not constitute a significant alteration in the ADOC’s lethal

injection protocol”:

             In attempting to avoid the legal prism typically used for analyzing
      similar Eighth Amendment claims, Williams asserts that he has a broad
      Eighth Amendment right to know the details of his execution in order to
      ensure proper oversight and avoid uncertainty that unnecessarily creates
      anxiety, which greatly exacerbates his sentence. Williams focuses on
      Nelson v. Campbell, 

, 

, 

      (2004), In re Medley, 

, 

, 

 (1890),
      and Gregg v. Georgia, 

, 

, 

      (1976), and he argues that these cases establish an Eighth Amendment
      right to know the details surrounding his execution.
             In Nelson, the ADOC altered its lethal injection
      protocol—approximately one week before defendant’s execution—to
      allow for a “cut-down” procedure. This involved making a two-inch
      incision in the defendant’s arm or leg and catheterizing a vein one hour
      before the execution with only local anesthetic. The state proposed the
      “cut down” procedure because standard techniques for gaining
      intravenous access were unavailable because of the defendant's past
      drug use. The holding of Nelson, however, is “extremely limited.” The
      Court simply concluded that 42 U.S.C. § 1983 was “an appropriate
      vehicle for petitioner’s Eighth Amendment claim seeking a temporary
      stay” based on altered execution protocols that could violate a
      defendant’s civil rights. It remanded the case for further proceedings to
      determine the merits of the defendant’s Eighth Amendment claim.
             In Medley, the Court, analyzing an ex post facto claim, concluded
      that a new Colorado statute imposed a greater penalty than its
      predecessor because the new law prohibited the warden from disclosing
      the execution date to the defendant, while the previous statute required

                                         33
       a court to inform the defendant of his execution date. Ultimately, the
       Court concluded that the “secrecy” surrounding an execution under the
       new statute “must be accompanied by an immense mental anxiety
       amounting to a great increase of the offender’s punishment,” and,
       therefore, the statute in question violated the Constitution’s ex post facto
       clause. See also Gregg, 428 U.S. at 173, 

 (prohibiting the
       “unnecessary and wanton infliction of pain”).
              We decline to read these cases as establishing a categorical rule
       entitling defendants to a lethal injection protocol that is legislatively
       enacted and subjected to extensive litigation. After an in camera review,
       the district court found that the State’s representations regarding the
       amended execution protocol were accurate and adequately informed
       Williams of the process that would be used. The replacement of sodium
       thiopental with pentobarbital does not constitute a significant alteration
       in the ADOC’s lethal injection protocol, and we conclude that such an
       amendment does not violate the Eighth Amendment under the cases
       cited by Williams.

Powell (Williams), 641 F.3d at 1257-58 (citations omitted; emphasis added). The

Court affirmed the district court’s denial of Williams’s motion to stay his

execution.

B.     Powell

       Powell filed his § 1983 action about a month before his scheduled execution

Process Clause.” Id. at 1302. Powell’s complaint further alleged: (1) “the drug

that the Defendants and ADOC now intend to use as the first drug in the [lethal

injection] sequence, pentobarbital, is not an ultra short acting barbiturate like

sodium thiopental”; (2) “[p]entobarbital is not an agent used medically to induce

loss of consciousness and loss of sensation, because of the extended length of time

it takes for the drug to act”; (3) “[p]entobarbital is less lipid soluble than sodium

thiopental, decreasing the rate of penetration into the brain, causing the slower

onset of anesthesia after intravenous injection”; (4) “[w]hile pentobarbital is used

to create a state of sedation, sedation is not the same as a loss of consciousness and

loss of sensation. Sedated individuals can be aware and can feel pain”; (5) “[i]f

pentobarbital is ineffectively administered and fails to establish and maintain loss

of consciousness and loss of sensation, [the second drug] pancuronium bromide

serves only to mask the inmate’s pain and suffering from observers, but does not

prevent the inmate from suffering a painful death by asphyxiation”; (6) “[a]bsent

complete anesthesia, the injection of [third drug] potassium chloride causes

excruciating pain”; (7) “there is no standard clinical dose of pentobarbital used to

induce anesthesia” because “[p]entobarbital is not even used medically to induce

                                          35
loss of consciousness and loss of sensation”; and (8) “the use of a drug not

approved to reliably induce full anesthesia creates a substantial risk of serious

harm to Mr. Powell.” (Emphasis added.)

      The State moved to dismiss Powell’s complaint as barred by the two-year

statute of limitations for § 1983 claims. Id. The district court granted the motion

to dismiss, concluding that “the statute of limitations for Powell’s challenge to

execution by lethal injection began running on July 31, 2002, the last time the

state made a ‘significant change’ in the state execution protocol by switching from

electrocution to lethal injection, and therefore [the period] expired on July 31,

2004.” Id.

      On appeal, Powell argued that the district court erred in granting the State’s

motion to dismiss his § 1983 action as time-barred because (1) the change from

sodium thiopental to pentobarbital was a “significant change” in the protocol and

thus re-started the limitations period, and the district court’s contrary holding

“relied on external evidence and dicta”; and (2) Powell’s “claim regarding

Alabama’s secrecy and arbitrary changes also accrued when the ADOC changed

the first drug in the protocol.” Id. This Court, applying de novo review and

accepting the allegations in Powell’s complaint as true, affirmed. Id.

      This Court first discussed the Powell (Williams) decision we had issued the

                                          36
month before:

             Powell is not the first Alabama death row inmate to bring these
      constitutional causes of action. A nearly identical complaint was filed
      by another Alabama death row inmate, Jason Oric Williams. . . .
             In Williams’s appeal, the Eleventh Circuit first addressed a § 1983
      claim identical to Powell’s Eighth Amendment claim, recognizing that
      “to prevail on such a claim there must be a ‘substantial risk of serious
      harm,’ an ‘objectively intolerable risk of harm’ that prevents prison
      officials from pleading that they were ‘subjectively blameless for
      purposes of the Eighth Amendment.’” We then rejected his claim,
      squarely holding that “[t]he evidence present does not demonstrate that
      the ADOC’s use of pentobarbital creates substantial risk of serious harm
      to Williams.”
             Turning to Williams’s notice claim, the Eleventh Circuit . . . noted
      that in the case before it, “the district court found that the State’s
      representations regarding the amended execution protocol were accurate
      and adequately informed Williams of the process that would be used.”
      Notably, we concluded: “The replacement of sodium thiopental with
      pentobarbital does not constitute a significant alteration in the ADOC’s
      lethal injection protocol, and . . . such an amendment does not violate
      the Eighth Amendment under the cases cited by Williams.” (emphasis
      added).

Powell, 643 F.3d at 1302-03 (citations omitted). The panel in Powell framed the

issue before it as “whether, in light of our prior precedent in Powell(Williams),

Powell’s claims are still viable.” Id.

      The Powell Court concluded that Powell (Williams) controlled and that

“Powell’s attempts to circumvent the holding of Powell(Williams) fall flat”:

            Powell claims that the basis of his first claim—that the ADOC’s
      lethal injection protocol violates the Eighth Amendment—has
      undergone a “significant change” . . . because of the recent change in the

                                          37
anesthetic used to ensure that there is no pain during the remaining
stages of the procedure. However, this very argument—that the ADOC’s
change from sodium thiopental to pentobarbital, is a substantial or
significant change in the lethal injection protocol—was rejected by a
panel of this Court in Powell(Williams), where we held that “[t]he
replacement of sodium thiopental with pentobarbital does not constitute
a significant alteration in the ADOC’s lethal injection protocol.”
(emphasis added). Indeed, as the Tenth Circuit has recognized, sodium
thiopental and pentobarbital are both classified as barbiturates. See
Pavatt v. Jones, 

, 1337 (10th Cir.2010). They differ in
their length of effect; sodium thiopental is “ultrashort-acting,” while
pentobarbital is “intermediate-acting”—which simply means its effect
lasts longer than that of sodium thiopental.
        Powell’s attempts to circumvent the holding of Powell(Williams)
fall flat. As for Powell’s claim that Powell(Williams)’s key language is
dicta, the Eleventh Circuit panel in that discussion was expressly
addressing Williams’s claim that he had an Eighth Amendment right to
know the details surrounding his execution. Williams had based his
claim, in part, on Nelson, 541 U.S. at 639, 

, where the
Supreme Court had concluded “that 42 U.S.C. § 1983 was ‘an
appropriate vehicle for petitioner’s Eighth Amendment claim seeking a
temporary stay’ based on altered execution protocols that could violate
a defendant’s civil rights.” (emphasis added). Applying Nelson to
Williams’s claim, the Powell(Williams) panel concluded that “[t]he
replacement of sodium thiopental with pentobarbital does not constitute
a significant alteration in the ADOC’s lethal injection protocol, and ...
such an amendment does not violate the Eighth Amendment under the
cases cited by Williams.” (emphasis added). Accordingly, the
Powell(Williams) panel necessarily answered whether the change in
lethal injection protocol was a significantly altered one in rejecting
Williams’s Nelson claim. Its language regarding whether the alteration
was significant, therefore, constitutes holding, not dicta. As we’ve said,
dicta is defined as those portions of an opinion that are not necessary to
deciding the case then before us, whereas holding is comprised both of
the result of the case and those portions of the opinion necessary to that
result by which we are bound.



                                   38
Id. at 1304-05 (citations and quotation marks omitted).

       Further, the Powell panel noted that “if the change in protocol is not a

‘significant alteration’ for purposes of an Eighth Amendment notice claim, we

cannot see how it would constitute a significant change for purposes of a statute of

limitations’ triggering date.” Id. at 1305. The Court also rejected the notion that

the Powell (Williams) holding should not control because Powell (Williams) was

decided on appeal from the denial of a stay of execution (which requires a

showing of substantial likelihood of success on the merits, under an abuse of

discretion standard), not a motion to dismiss (decided de novo, accepting

plaintiff’s allegations as true):

       [W]e recognize that Williams’s claim in Powell(Williams) was decided
       on an appeal from the district court’s denial of a motion for a temporary
       stay of execution. However, as the district court noted, no reason has
       been offered, and none can be envisioned, why Powell(Williams)’s
       holding would mean something different when analyzing whether a
       change in execution protocol is significant or substantial in either
       circumstance. In both cases, the allegations are identical, and the
       Powell(Williams) Court clearly went to the merits of the issue when
       ruling on the motion for stay. Thus, not only do we reject Powell’s
       suggestion that the district court erroneously relied on external evidence
       from Powell(Williams), and went beyond the face of Powell’s complaint
       in deciding this case, but we conclude that the district court did not err
       in basing its conclusion on our binding precedent in Powell(Williams),
       which applies here. Furthermore, in light of our binding precedent, we
       are obliged to reject Powell’s attempt to relitigate the issue of whether
       the ADOC’s action in changing the first drug in the lethal injection
       protocol from sodium thiopental to pentobarbital is a “significant”

                                          39
        change for purposes of [the statute of limitations]. For these reasons, the
        district court did not err in determining that Powell’s claim is barred by
        the statute of limitations.

Id. at 1305 (emphasis added).

        We also affirmed the district court’s decision to dismiss as time-barred

Powell’s claim as to the secrecy of Alabama’s execution protocol:

        Nor, moreover, did the district court err in dismissing Powell’s second
        claim—that his rights under the Eighth and Fourteenth Amendments
        were violated because Alabama’s private execution protocol was
        changed secretly and without any oversight—on statute of limitations
        grounds. As the district court held, Powell could have challenged the
        ADOC’s “secrecy” surrounding the method of execution beginning July
        31, 2002, as the facts supporting this cause of action should have been
        apparent to any person with a reasonably prudent regard for his rights.
        Indeed, as Powell acknowledges in his opening brief, “Alabama does not
        mandate by statute or regulation what drugs are to be used in conducting
        a lethal injection, and the ADOC may change the drugs used in the
        protocol at any time for any reason without notice or oversight[,] . . .
        [and the drug used] is subject to change at any time.” Thus, Powell fails
        to show how his claim about the secrecy surrounding the ADOC’s
        recent change in lethal injection protocol was revived by the ADOC’s
        2011 switch in drugs. And in any event, this very claim was also
        rejected by this Court in Powell(Williams), which, as noted above,
        constitutes binding precedent.

Id. at 1305 (quotation marks and citations omitted). Thus, Arthur’s very claims

about pentobarbital were rejected in Powell and Powell (Williams). But there is

more.

C.      DeYoung



                                            40
      On May 13, 2011, the Georgia Department of Corrections (“GDOC”), like

its Alabama counterpart, switched the first drug in its three-drug lethal injection

protocol from sodium thiopental to pentobarbital. DeYoung, 646 F.3d at 1322-23.

On July 15, 2011, Georgia death row inmate Andrew DeYoung, who was

scheduled to be executed five days later, filed a § 1983 action challenging

Georgia’s method of execution on Eighth Amendment and Equal Protection

grounds. Id. at 1322. Just as Arthur’s does here, DeYoung’s complaint alleged

that the Blankenship and Powell executions showed pentobarbital did not work

fast enough. DeYoung even used the affidavits of Powell’s same attorneys and the

same Bluestein news article as Arthur does here.

      Specifically, DeYoung’s complaint alleged, inter alia: (1) reporter Greg

Bluestein’s account of the Blankenship execution, particularly Blankenship’s

movements during the procedure and his eyes remaining open, demonstrated that

“Georgia’s first execution with pentobarbital went wrong”; (2) based on the

Bluestein account, DeYoung’s expert witnesses opined that “Blankenship

suffered”; (3) the State’s assurances “that pentobarbital works as fast as sodium

thiopental and that a person will be unconscious within ‘thirty to sixty seconds’

after receiving” pentobarbital “proved to be incorrect”; (4) based on the affidavits

by Powell’s attorneys Freeman and Schulz, Powell also “reacted adversely to

                                          41
pentobarbital”; (5) “[p]entobarbital is not used to anesthetize fully awake

humans”; (6) there was not enough data to know “how an overdose of

pentobarbital will affect basically healthy inmates”; (7) “pentobarbital has not

been sufficiently tested to render an entirely conscious human adult unconscious”;

and (8) the State’s use of pentobarbital “inflicted pain and needless suffering on

Mr. Blankenship” and is “very likely” to do so to DeYoung. (Emphasis added.)

DeYoung moved for a stay of execution, and the State of Georgia moved to

dismiss the complaint as time-barred and for failure to state a claim upon which

relief could be granted. Id.

      The district court held an evidentiary hearing, after which it denied

DeYoung’s motion to stay the execution and granted the State’s motion to dismiss.

Id. The district court concluded that: (1) the two-year statute of limitations period

expired eight years before DeYoung filed his claims because, inter alia, the switch

to pentobarbital was not a significant alteration to the execution protocol; and (2)

alternatively, DeYoung’s complaint failed to state a claim. Id. at 1323. We

described DeYoung’s claims and the district court’s alternative grounds for

dismissal as follows:

             DeYoung’s challenge to the State’s method of execution is
      two-pronged. First, he contends the GDOC’s lethal injection protocol
      violates the Eighth Amendment’s prohibition of cruel and unusual

                                         42
punishment. Specifically, DeYoung alleges, among other things, that the
use of pentobarbital as an anesthetic poses a substantial risk of serious
harm to him because: (1) pentobarbital has been insufficiently tested for
induction of anesthetic coma in fully conscious persons, and (2) in prior
executions using pentobarbital, the drug did not painlessly anesthetize
the prisoners.
       Second, DeYoung contends the GDOC’s lethal injection protocol,
as written and as administered in practice, violates his right to equal
protection under the Fourteenth Amendment because: (1) the written
protocol contains gaps in the execution procedure that the GDOC fills
in on an ad hoc basis, leading to disparate treatment for different
inmates; and (2) the GDOC deviates from the written protocol, similarly
leading to disparate treatment for different inmates. . . .
...
       . . . [T]he district court concluded that DeYoung failed to state a
claim upon which relief could be granted. As to the Eighth Amendment
claim, the district court found, among other things: (1) DeYoung’s
evidence failed to show that the administration of pentobarbital inflicts
serious harm; (2) DeYoung has not proven that former inmate Roy
Blankenship (who on June 23, 2011 was executed by the State of
Georgia using pentobarbital as the anesthetic) suffered pain or serious
harm; (3) that DeYoung’s expert “failed to provide a medical
explanation for why pentobarbital might have caused Blankenship pain”
and “[t]o the contrary, Dr. Waisel testified that a patient will not feel
pain at the moment when a drug is introduced intravenously unless it is
a drug, such as potassium chloride, which causes a burning sensation”;
(4) DeYoung presented no evidence indicating a 5,000–milligram dose
of pentobarbital fails to cause unconsciousness; (5) a consciousness
check was performed on Roy Blankenship prior to injection of the
second drug pancuronium bromide as required by Georgia’s legal
injection procedure; and (6) executions in Georgia do not proceed with
the second drug until the inmate is unconscious and “DeYoung’s
execution cannot proceed until he is unconscious.” Thus, DeYoung did
not show that Georgia’s use of pentobarbital creates a substantial risk of
serious harm to inmates.
       As to DeYoung’s Fourteenth Amendment claim, the district court
found: (1) there was no support for “DeYoung’s novel proposition” that

                                   43
      the Equal Protection Clause requires the State to “produce a written
      protocol that is detailed enough to insure that every execution is
      precisely identical”; (2) the “deviations” from the written protocol of
      which DeYoung complains (including the use of nurses to insert IVs, the
      presence of two nurses instead of one, performance of numerous
      consciousness checks, and checks for IV infiltration or leakage) are
      consistent with Georgia’s written protocol and “enure to the benefit” of
      inmates; and (3) the benign “deviations” are rationally related to the
      State’s interest in safeguarding the execution process. Thus, DeYoung
      did not show an equal protection violation.

DeYoung, 646 F.3d at 1323-24 (brackets omitted) (emphasis added). The district

court denied a stay of execution or other injunctive relief because it concluded

DeYoung had “absolutely no likelihood of success on the merits.” Id. at 1324

(quotation marks omitted).

      DeYoung appealed the district court’s dismissal of his complaint and denial

of his motion for a stay of execution. Id. DeYoung also moved this Court for a

stay. Id. We denied DeYoung’s stay motion and affirmed. Id. at 1324, 1328. In

doing so, we concluded that “DeYoung’s claims are barred by the statute of

limitations and, even if they were timely, they fail as a matter of law.” Id. at 1324.

      As to the statute of limitations, this Court concluded that “DeYoung last

became subject to a new or substantially changed execution protocol on October 5,

2001,” when Georgia switched from electrocution to lethal injection, and thus his

limitations period expired nearly eight years before he brought his § 1983 action.



                                          44
Id. at 1325. The DeYoung panel expressly rejected DeYoung’s argument, which

is the same one Arthur makes, that the substitution of pentobarbital for sodium

thiopental was a substantial change, concluding that (1) Powell (Williams) and

Powell were binding authority on that point, and (2) DeYoung’s new evidence

about pentobarbital did not change that fact:

             DeYoung argues that Georgia’s May 13, 2011 substitution of
      pentobarbital for sodium thiopental as the anesthetic in its lethal
      injection protocol resulted in a “substantially changed execution
      protocol.” We already rejected an identical claim as to Alabama’s recent
      switch from sodium thiopental to pentobarbital. See Powell, 

, at *2–4 (rejecting Eighth Amendment challenge to method of
      execution on statute of limitations grounds, stating, “this very
      argument—that the ADOC’s change from sodium thiopental to
      pentobarbital, is a substantial or significant change in the lethal injection
      protocol—was rejected by a panel of this Court in Powell (Williams),”
      and “Powell’s attempts to circumvent the holding of Powell (Williams)
      fall flat”); see also Powell (Williams), 641 F.3d at 1258 (“The
      replacement of sodium thiopental with pentobarbital does not constitute
      a significant alteration in the ADOC’s lethal injection protocol ....”).
             DeYoung acknowledges the Powell decision is on point, but
      argues that the evidence he proffered in this record undermines the
      premise of Powell. However, “the mere act of proffering additional
      reasons not expressly considered previously will not open the door to
      reconsideration of the question by a second panel.” Smith v. GTE Corp.,
      

, 1302 (11th Cir.2001) (quotation marks and ellipsis
      omitted). And in any event, the additional evidence DeYoung proffers
      does not, for the reasons set forth below, undermine Powell’s
      conclusion.

Id. at 1325 (emphasis added).

      The Court, as an alternative holding independent of its statute of limitations

                                           45
conclusion, then discussed the merits of DeYoung’s Eighth Amendment and

Fourteenth Amendment claims. Id. at 1325-28. As to the Eighth Amendment

claim, DeYoung alleged that evidence from witnesses to Georgia’s June 23, 2011

execution of Roy Blankenship supported DeYoung’s claims that (1) the

administration of 5,000 milligrams of pentobarbital, as Georgia’s protocol

requires, causes needless suffering, and (2) the pentobarbital did not adequately

render an inmate unconscious.12 Id. at 1325-26.

       As part of its alternative merits holding, the Court reviewed the evidence

presented in the district court, including the affidavits from witnesses to

Blankenship’s execution stating that Blankenship moved during the execution and

the testimony of DeYoung’s expert Dr. Waisel that such movements demonstrated

that Blankenship suffered. Id. at 1326-27. This Court noted that (1) although the

witness accounts disagreed as to the type and timing of Blankenship’s movements,

“[t]he evidence undisputedly shows that Blankenship became still and was

unconscious before the second drug was administered”; (2) Dr. Waisel provided

no medical explanation for why pentobarbital would cause Blankenship pain; (3)


       12
         DeYoung also claimed that pentobarbital had not been tested sufficiently for its ability
to induce an anesthetic coma in humans, but as DeYoung’s own expert admitted he did not—and
could not—know how pentobarbital could affect inmates because of this lack of testing, the
Court held that this contention “obviously cannot satisfy DeYoung’s burden of affirmatively
showing that a substantial risk of serious harm exists.” DeYoung, 646 F.3d at 1326 n.4.

                                               46
“Blankenship’s autopsy revealed no evidence of trauma”; and (4) “DeYoung

presented no evidence to show that unconsciousness is not achieved after the

complete administration of a 5000–mg dose of pentobarbital.” Id. DeYoung also

submitted evidence that Powell’s execution by the State of Alabama showed that

pentobarbital created a substantial risk of serious harm, but this Court rejected that

claim as well:

        In addition to the evidence concerning the Blankenship execution,
        DeYoung submitted some evidence regarding the execution of Eddie
        Powell, who was recently executed in Alabama using a
        pentobarbital-pancuronium bromide-potassium chloride protocol.
        DeYoung’s evidence about the Powell execution does not change our
        conclusion. Powell’s attorney, who witnessed Powell’s execution,
        testified that about a minute after the Chaplain finished praying with
        Powell, Powell (1) lifted his head, (2) looked confused, and (3) clenched
        his teeth and flexed his neck muscles as if he were extremely angry or
        tense or nervous. After about a minute more, Powell lay back down,
        closed his eyes, and did not move again. Powell’s counsel did not know
        at what time the various chemicals were administered.

Id. at 1327 n.5. The DeYoung panel concluded, “DeYoung has wholly failed to

show that pentobarbital, once fully administered and allowed to act, is ineffective

as an anesthetic. As the district court succinctly found, Georgia’s ‘use of

pentobarbital does not create a substantial risk of serious harm to inmates.’” Id. at

1327.

        This Court also considered, and rejected, DeYoung’s equal protection claim,



                                           47
as follows:

              DeYoung’s equal protection claim asserts, essentially, that
       Georgia’s written lethal injection protocol is insufficiently specific and
       thus the GDOC deviates from it on an ad hoc basis, leading to disparate
       treatment for different inmates. DeYoung has not shown a substantial
       likelihood of success on the merits of this claim.
              First, as the district court correctly noted, there is no support for
       DeYoung’s “novel proposition” that the Equal Protection Clause
       requires a written execution protocol sufficiently detailed to ensure that
       every execution is performed in a precisely identical manner. Moreover,
       our review of the Georgia lethal injection protocol reveals it to be highly
       detailed as to nearly every aspect of the execution process.
              Second, the “deviations” DeYoung cites that lead to the disparate
       treatment of which he complains [including having one more nurse
       present, and performing more consciousness checks, than the written
       protocol requires] are all ways by which the GDOC provides more
       protection for an inmate and the execution process than the written
       protocol provides. The State has a legitimate interest in ensuring that its
       executions occur in a thorough manner with maximum inmate
       safeguards, and the alleged deviations from the written protocol are
       rationally related to that interest. DeYoung has not shown a substantial
       likelihood of success on his equal protection claim.

Id. at 1328.13

D.     Valle

       Like Arthur in Alabama, Florida death row inmate Manuel Valle tried to

       13
         As a result of litigation by another Georgia death row inmate about the use of
pentobarbital as the first drug in Georgia’s three-drug lethal injection protocol, a Georgia trial
court ordered DeYoung’s July 20, 2011 execution to be videotaped. Despite the claims raised
before DeYoung’s execution about the efficacy of pentobarbital and the time it took for
pentobarbital to render an inmate unconscious, to date no one has raised any allegations of
problems with the DeYoung execution. Arthur relies on the same allegations concerning the
Powell and Blankenship executions that were brought before the district court and this Court in
DeYoung.

                                                48
circumvent Eleventh Circuit precedent about the State’s substitution of

pentobarbital for sodium thiopental in Valle v. Singer, 

 (11th Cir.

2011). Valle’s complaint alleged: (1) the State’s substitution of pentobarbital for

sodium thiopental “create[s] a substantial risk of serious harm and undue pain and

suffering, particularly from awareness while being paralyzed and receiving

potassium chloride”; (2) “[t]he use of pentobarbital as an agent to induce

anesthesia is not FDA approved, has no relevant clinical history and has no

relevant clinical reference doses on which to determine what dose would cause a

clinically adequate depth of anesthesia, much less an adequate lethal injection

dose”; (3) “[t]he injection of pancuronium bromide and/ or potassium chloride will

cause excruciating pain and suffering if administered to a condemned inmate who

is not sufficiently anesthetized”; (4) “[s]odium thiopental is an ultra-short acting

barbiturate which acts to depress the central nervous system to produce

unconsciousness and anesthesia,” whereas “[p]entobarbital is a short-acting

barbiturate approved by the Food and Drug Administration (FDA) for the

treatment of seizures, preoperative (and other) sedation, and use as a hypnotic”;

(5) “[p]entobarbital has not been FDA-approved for the induction of anesthesia,

has no relevant clinical history, and has no relevant clinical reference doses by

which to determine an appropriate dosage for a clinically adequate depth of

                                          49
anesthesia to avoid the excruciating pain caused by an injection of potassium

chloride”; (6) Georgia “botched the execution of Roy Willard Blankenship, its first

using pentobarbital”; (7) “Blankenship was inadequately anesthetized and was

sentient for approximately the first three minutes of the execution and he suffered

greatly”; (8) “[t]here is no way to know, in any given case, how a massive dose of

pentobarbital will affect a human patient, because it has not been tested to any

remotely sufficient degree to be able to say”; and (9) “[t]here are also serious

concerns about the adequacy of monitoring for continuing consciousness of the

inmate after injection of pentobarbital, particularly in light of lack of information

available about how fast pentobarbital takes effect in a lethal injection scenario.”

The district court denied Valle’s motion for an injunction and a stay of execution,

and Valle appealed.

      After reviewing our precedent, this Court adopted the district court’s

opinion, which concluded that: (1) Florida, by substituting pentobarbital as the

first drug, did not make a significant alteration in its lethal injection protocol; (2)

“Valle’s protestations notwithstanding, the purported distinctions upon which he

relies are neither new nor, based on Eleventh Circuit precedent, are they sufficient

alone or in combination with one another to carry his burden”; (3) Valle’s “attempt

to distinguish his claim from the binding Powell precedent, based upon the

                                           50
Blankenship execution and the affidavit of Dr. Waisel, is significantly undermined

if not entirely foreclosed by DeYoung []”; and (4) Valle “failed to support his

assertion that his case is distinguishable from the Eleventh Circuit’s decisions in

the Powell cases and DeYoung [], and mere speculation cannot substitute for

evidence that the use of pentobarbital will or very likely will cause serious illness

and needless suffering.” 655 F.3d at 1231-33.

      With this binding precedent as background, I turn to Arthur’s claims on

appeal.

                                  III. ANALYSIS

A.    Eighth Amendment Claim

      Arthur argues the district court erred in dismissing as time-barred his claim

that the ADOC’s lethal injection protocol violates the Eighth Amendment’s ban on

cruel and unusual punishment. Arthur does not dispute that his Eighth

Amendment claim is untimely unless the ADOC’s switch to pentobarbital

constitutes a significant or substantial alteration in the execution protocol. See

Powell, 643 F.3d at 1303-04 (citing McNair v. Allen, 

, 1174, 1177

(11th Cir. 2008)). Nor does he dispute that in Powell (Williams), Powell,

DeYoung, and Valle, this Court stated that the substitution of pentobarbital for

sodium thiopental “does not constitute a significant alteration.” Powell

                                          51
(Williams), 641 F.3d at 1258; Powell, 643 F.3d at 1303-05; DeYoung, 646 F.3d at

1325; Valle, 655 F.3d at 1233. Instead, Arthur argues that our previous opinions

in those cases are not “‘binding precedent’ that control the outcome of Mr.

Arthur’s case.”

      As this Court expressly did in Powell, DeYoung, and Valle, I reject the

contention that we are not bound by our earlier precedent on the effect of the

pentobarbital substitution on the statute of limitations. See DeYoung, 646 F.3d at

1325 (“DeYoung acknowledges the Powell decision is on point, but argues that

the evidence he proffered in this record undermines the premise of Powell.

However, ‘the mere act of proffering additional reasons not expressly considered

previously will not open the door to reconsideration of the question by a second

panel.’”); Powell, 643 F.3d at 1304-05 (“Powell’s attempts to circumvent the

holding of Powell(Williams) fall flat. . . . [I]n light of our binding precedent, we

are obliged to reject Powell’s attempt to relitigate the issue of whether the

ADOC’s action in changing the first drug in the lethal injection protocol from

sodium thiopental to pentobarbital is a ‘significant’ change . . . .”); see also Valle,

655 F.3d at 1232 (“Plaintiff’s attempt to distinguish his claim from the binding

Powell precedent, based upon the Blankenship execution and the affidavit of Dr.

Waisel relied upon by Valle, is significantly undermined if not totally foreclosed

                                           52
by DeYoung [].” (citation omitted)).

      The district court correctly held that Arthur’s Eighth Amendment claim was

filed outside the limitations period, based on our holdings in Powell (Williams),

Powell, DeYoung, and Valle. We have held a number of times that a prior panel

precedent cannot be circumvented or ignored on the basis of arguments not made

or factors not considered by the prior panel. See, e.g., Tippitt v. Reliance Standard

Life Ins. Co., 

, 1234 (11th Cir. 2006) (“[A] prior panel precedent

cannot be circumvented or ignored on the basis of arguments not made to or

considered by the prior panel.”); Saxton v. ACF Indus., 

, 1215 (11th

Cir.) (“That holding [of the earlier panel] is the law of this Circuit regardless of

what might have happened had other arguments been made to the panel that

decided the issue first.” (quotation marks and citation omitted)), rev’d en banc on

other grounds, 

 (11th Cir. 2001) (en banc); Smith v. GTE Corp., 

, 1302-03 (11th Cir. 2001) (categorically rejecting an “overlooked

reason” exception to the prior panel precedent rule); Turner v. Beneficial Corp.,

, 650 (11th Cir.) (“Nor is the operation of the rule dependent upon

the skill of the attorneys or wisdom of the judges involved with the prior

decision—upon what was argued or considered.”), rev’d en banc on other

grounds, 

 (11th Cir. 2001) (en banc); Cohen v. Office Depot, Inc.,

                                          53


, 1076 (11th Cir. 2000) (same).

       Arthur contends we are not bound by our prior decisions about the

significance of the switch to pentobarbital because it is a factual issue, not a legal

question. However, the “interpretation and application of a statute of limitations is

a question of law.” Lawrence v. Florida, 

, 1224 (11th Cir. 2005);

accord United States v. Trainor, 

, 1330 (11th Cir. 2004) (stating that

the “application of [a] statute of limitations is [a] question of law reviewed de

novo”). And our precedent has already held that the substitution of pentobarbital

for sodium thiopental is not a significant change in Alabama’s lethal injection

protocol to restart the statute of limitations clock. See Valle, 655 F.3d at 1233;

DeYoung, 646 F.3d at 1325; Powell, 643 F.3d at 1304-05; Powell (Williams), 641

F.3d at 1258.14

       Alternatively, to the extent there is a mixed question of law and fact as to

whether the change to pentobarbital is a significant alteration, the prior panel

precedent rule obligates us to apply a prior panel decision “to facts and

circumstances sufficiently similar to those under which [the prior decision] arose,”

       14
          In any event, the statute of limitations question at issue here does not turn on a broad
fact-intensive inquiry into how Alabama administers its lethal injection protocol, but rather on
the narrow issue of whether the substitution of pentobarbital for sodium thiopental constitutes a
“significant alteration.” This explains why this Court held that the Powell (Williams) and Powell
holdings as to Alabama’s protocol were binding precedent as to the same challenges to Georgia’s
and Florida’s switch to pentobarbital.

                                               54
Anders v. Hometown Mortg. Servs., Inc., 

, 1031 (11th Cir. 2003),

and here, the “facts and circumstances” are nearly, if not completely, identical.

      The ADOC lethal injection protocol challenged in Powell (Williams) and

Powell is identical to the protocol challenged by Arthur. In all three Alabama

cases (and in Georgia’s DeYoung and Florida’s Valle as well), the claim is that the

use of pentobarbital creates a substantial risk of serious harm because of the

possibility that it will not timely render the inmate unconscious and insensate

before administration of the second and third drugs in the protocol.

      Likewise, the factual bases of the claims are nearly identical. Arthur neither

alleges nor attaches to his complaint any new scientific or medical evidence about

pentobarbital. Instead, his complaint makes the same factual contentions that were

considered and rejected in Powell (Williams), Powell, DeYoung, and Valle.

Indeed, Arthur even attaches to his complaint the expert report of Dr. Dershwitz,

which was the same key evidence in Powell (Williams).

      Arthur contends his case is not about the dosage of pentobarbital but rather

about the amount of time needed for pentobarbital to render an inmate

unconscious before the second drug is given. But, as shown above, how fast-

acting or how long it takes for pentobarbital to act was expressly part of the

allegations in the prior cases. In Powell (Williams), Williams alleged that: (1)

                                         55
pentobarbital is not interchangeable with sodium thiopental because pentobarbital

is a longer-acting barbiturate than thiopental; (2) pentobarbital is not used

clinically to induce anesthesia, but is instead a sedative; (3) “pentobarbital is not

an agent used medically to induce loss of consciousness and loss of sensation

because of the extended length of time it takes for the drug to act”; (4)

pentobarbital is less lipid-soluble than sodium thiopental, “causing the slower

onset of anesthesia after intravenous injection”; and (5) pentobarbital’s lack of

clinical testing precludes an accurate assessment of its proper dosage or its

efficacy. In Powell, Powell alleged that: (1) sodium thiopental is an anesthetic,

whereas pentobarbital is a sedative; (2) sedation is not the same as a loss of

consciousness and sensation; (3) the lack of clinical history of pentobarbital as an

anesthetic puts the inmate at an undue risk of suffering; and (4) pentobarbital is

not effective to induce loss of consciousness “because of the extended length of

time it takes.” And although Arthur’s complaint details the story of the Powell

and Blankenship executions, DeYoung and Valle featured the same reports of

witnesses from the Powell and Blankenship executions, but the DeYoung Court

already held that evidence did not show a substantial risk of serious harm and in

any event did not restart the statute of limitations clock. DeYoung, 646 F.3d at

1325-27; see Valle, 655 F.3d at 1228-38 (evaluating evidence regarding the

                                          56
Blankenship and Powell executions and ultimately holding that the appellant’s

lethal injection action was time barred); see also Jackson v. Danberg, 

, 163-64 & n.6 (3d Cir. 2011) (concluding use of pentobarbital did not create

or demonstrate risk of severe pain despite the inmate’s presentation of evidence

concerning the Blankenship and Powell executions).15

       In short, the district court correctly applied our binding circuit precedent in

holding that Arthur’s Eighth Amendment claim was barred by the statute of

limitations.

       Although I believe we are bound by our own precedent, I note that every

other circuit to consider the issue has uniformly concluded that the use of

pentobarbital, in lieu of sodium thiopental, as the first drug in lethal injection

executions is constitutional. See Jackson, 656 F.3d at 162-65; Pavatt v. Jones, 

, 1339-40 (10th Cir. 2010); see also Beaty v. Brewer, 

,

1075-76 (9th Cir. 2011) (Kozinski, J., concurring in denial of rehearing en banc)

(stating inmate had challenged substitution of pentobarbital for sodium thiopental,

noting that Tenth and Eleventh Circuits had rejected similar claims, and


       15
         Moreover, under Alabama’s protocol, the execution cannot proceed until three
consciousness checks are performed. Even Arthur’s own evidence shows that the 2,500 mg dose
of pentobarbital produces unconsciousness and lack of sensation in inmates. And what is more,
Alabama has instituted procedural safeguards—the three different types of consciousness
checks—to confirm the loss of consciousness before administration of the second drug.

                                             57
concluding that petitioner had failed to show any deficiency in Tenth or Eleventh

Circuit’s analysis). Indeed, the Third Circuit pointed out how pentobarbital is

commonly used to euthanize terminally ill patients and that there is no scientific

evidence that pentobarbital “fails to render an inmate unconscious”:

       “Pentobarbital is a barbiturate commonly used to euthanize terminally
       ill patients who seek death with dignity in states such as Oregon and
       Washington.” Beaty v. Brewer, 

, at 1075, 

, at *4 (9th Cir. 2011) (denying rehearing en banc because
       inmate had no likelihood of success on Eighth Amendment claim based
       on pentobarbital). It has been used successfully for executions in at
       least four other states, and there is no evidence that it fails to render an
       inmate unconscious.

Jackson, 656 F.3d at 165.16 Here, Arthur’s own voluminous evidence, attached to

his complaint, shows pentobarbital works.

B.     Due Process Claim

       Similarly, I conclude that the district court properly applied our precedent in

dismissing as barred by the statute of limitations Arthur’s Due Process claim as to

the secrecy of Alabama’s lethal injection protocol. In Powell, we expressly noted

that the ADOC’s alteration in its lethal injection protocol to substitute the use of

pentobarbital for sodium thiopental was not a significant alteration either for

purposes of an inmate’s claim that he had a right to know the details of his


       16
          Since early 2011, twelve states (including Alabama) have used pentobarbital in carrying
out at least 44 executions. See http://www.deathpenaltyinfo.org (Last visited March 20, 2012).

                                               58
execution or “for purposes of a statute of limitations’ triggering date.” Powell,

643 F.3d at 1304-05. We also stated that Powell’s very claim “about the secrecy

surrounding the ADOC’s recent change in lethal injection protocol” was “rejected

by this Court in Powell(Williams), which . . . constitutes binding precedent.” Id.

at 1305. As with Arthur’s Eighth Amendment claim, his Due Process claim rests

upon the same factual allegations and legal arguments that were considered and

rejected in Powell (Williams) and Powell.

      Moreover, and in any event, Arthur has pointed to no facts in this record

that would indicate that his Due Process claim did not arise or could not have been

brought in 2002, when Alabama established its lethal injection protocol. See

Powell, 643 F.3d at 1305 (“Powell could have challenged the ADOC’s ‘secrecy’

surrounding the method of execution beginning July 31, 2002, as the facts

supporting this cause of action should have been apparent to any person with a

reasonably prudent regard for his rights. . . . Powell fails to show how his claim

about the secrecy surrounding the ADOC’s recent change in lethal injection

protocol was revived by the ADOC’s 2011 switch in drugs.”). The district court

properly dismissed this claim.

C.    Equal Protection Claim

      I also conclude that the district court correctly dismissed Arthur’s equal

                                         59
protection claim under Rule 12(b)(6) for failure to state a claim upon which relief

can be granted. As stated above, to survive dismissal under Rule 12(b)(6), a

plaintiff’s complaint “must contain factual allegations that, if true, would ‘raise a

right to relief above the speculative level.’” Speaker, 623 F.3d at 1380. And, to

state an equal protection claim, Arthur must show: (1) “that the State will treat him

disparately from other similarly situated persons,” and (2) that the disparate

treatment burdens a fundamental right, targets a suspect class, or is not rationally

related to a legitimate government interest. DeYoung, 646 F.3d at 1327-28;

Houston v. Williams, 

, 1363 (11th Cir. 2008).

      Arthur alleges that the third consciousness check (the arm pinch) was not

performed during the Powell execution, and this failure indicates that Arthur

himself will be treated differently than the ADOC treats other inmates (except for

Powell, presumably) being executed under the lethal injection protocol. Arthur

alleges that this disparate treatment burdens his fundamental Eighth Amendment

right to be free from cruel and unusual punishment because it creates a substantial

risk that he will suffer serious harm during his execution.

      Arthur has wholly failed to meet his burden of alleging facts that would

plausibly show either disparate treatment or the burdening of a fundamental right.

All Arthur has alleged in support of his equal protection claim is that two of the

                                          60
witnesses to Powell’s execution (Powell’s attorneys) saw ADOC officials perform

the first two consciousness checks on Powell but did not see the third check—the

arm pinch.17 The undisputed evidence, however, is that Powell was unconscious

before the second and third drugs were administered.

       Even assuming that ADOC officials did not perform the third consciousness

check during the Powell execution, it is no more than rank speculation to conclude

that ADOC officials will in the future treat Arthur differently than similarly

situated inmates. Arthur has alleged no pattern, practice, or even reason for the

alleged failure to perform the arm pinch, and none can reasonably be inferred.

There are only Arthur’s admissions that two consciousness checks in the ADOC’s

protocol were performed on Powell and one isolated report of an alleged failure to

follow the third consciousness check in the ADOC’s protocol. There is nothing

more than speculation that it will occur again, much less that it will occur in

Arthur’s case.

       Furthermore, Arthur’s own experts do not indicate that the arm pinch is

necessary to prevent a substantial risk of serious harm that would constitute an

Eighth Amendment violation. Dr. Lubarsky stated in his declaration that



       17
        The affidavits of Anne Hill and Warden Patterson report that all three consciousness
checks were performed. But for purposes of this appeal, I focus on Arthur’s evidence.

                                              61
“[p]inching an inmate’s arm after the administration of pentobarbital, especially by

someone who is not extensively trained, is not an acceptable way to determine

consciousness.” (Emphasis added.) Dr. Heath, though he termed the arm pinch

“one of the key aspects of [the ADOC] protocol,” did not allege that the failure to

perform the pinch would create a substantial risk of serious harm. Instead, Dr.

Heath merely indicated that if the ADOC is not performing the arm pinch

consciousness check, “it demonstrates an unacceptable sloppiness or lack of

diligence on the part of the ADOC, and means that the ADOC cannot be relied

upon to administer lethal injection in a humane fashion.” In other words, Dr.

Heath appears to allege not that the failure to perform the arm pinch consciousness

check itself creates a substantial risk of serious harm, but that such failure

furnishes evidence indicating that the ADOC may also fail to perform other

features of its protocol, and those other failures will create a substantial risk of

serious harm. And again, in light of our own precedent, Arthur has not shown

either (1) that pentobarbital fails to achieve unconsciousness and lack of sensation

before the second drug is administered, or (2) even in the Powell execution, that

Powell was not unconscious before he was given the second drug in the protocol.

Thus, even if Arthur could show the failure to perform the third consciousness

check on Powell would result in disparate treatment of Arthur, he has not alleged

                                           62
enough facts that, if taken as true, would show that the failure to perform Powell’s

arm pinch burdens Arthur’s Eighth Amendment right.

      I conclude that the district court did not err in dismissing Arthur’s equal

protection claim.

                               IV. CONCLUSION

      For the reasons stated above, our precedent requires that we affirm the

dismissal of Arthur’s complaint. I respectfully dissent.
