Wе hereby withdraw our previous opinion of February 10, 2016 and substitute the following.
Plaintiffs Richard Jordan and Ricky Chase and Intervenor Thomas Loden are prisoners awaiting execution in the state of Mississippi. They sued under § 1983 in federal district court seeking an injunction preventing the state from conducting executions with compounded pentobarbital. The district court granted a broad рreliminary injunction. Because Mississippi’s sovereign immunity prevents a federal court from enjoining state officials to follow state law, and because Plaintiffs
I.
Richard Jordan was sentenced to death following his conviсtion on charges of kidnapping and murdering Edwina Marter on January 13, 1976. Jordan v. State,
Mississippi law provides that “the manner of inflicting the punishment of death shall be by continuous intravenous administration of a lethal quantity of an ultra short-acting barbiturate or other similar drug in combination with a chemical paralytic agent until death is pronounced.” Miss. Code Ann. § 99-19-51. At the time this lawsuit began, the state’s lethal injection protocol called for the infusion of sodium pentothal or, if sodium pentothal could not be obtained, pentobarbital as the first drug in a three-drug cocktail. Plaintiffs sued various state officers seeking an injunction forbidding the use of pentobarbi-tal as contrary to § ,99-19-51’s requirement of an “ultra short-aсting barbiturate or other similar drug” and forbidding the use of compounded drugs which they alleged violated their Eighth and Fourteenth Amendment rights.
Immediately before the district court conducted a hearing on Plaintiffs’ motion for a preliminary injunction, Mississippi substituted a revised lethal injection protocol that allowed it to use midazo-lam as the first drug in the three-drug cocktail if it could not obtain sodium pento-thal or pentobarbital. The district court concluded Plaintiffs had demonstrated a substantial likelihood of success “at least, on their claim that Mississippi’s failure to use a drug which qualifies as an ‘ultra short-acting barbiturate or other similar
II.
In order to obtain a preliminary injunction, the party seeking the injunсtion must establish:
(1) a substantial likelihood of success on the merits, (2) a substantial threat of irreparable injury if the injunction is not issued, (3) that the threatened injury if the injunction is denied outweighs any harm that will result if the injunction is granted, and (4) that the grant of an injunction will not disserve the public interest.
Sepulvado v. Jindal,
“To assess the likelihood of success on the merits, we look to standards provided by the substantive law.” Sepulvado,
Because the district court was not clear as to which aspect of the due process clause Mississippi’s protocol violates, we examine both prongs.
A.
We begin by examining whether Plaintiffs can show Mississippi’s proposed method of execution violates the procedural protections of the Fourteenth Amendment because it fails to conform to state law. The Fourteenth Amendment’s right to procedural due process guarantees citizens the protection of adequate procedures before allowing a stаte to deprive them of their property, liberty, or life. Liberty interests protected by the Fourteenth Amendment “may arise from the Constitution itself, by reason of guarantees implicit in the word ‘liberty,’ or it may arise from an expectation or interest created by state laws or policies.” Wilkinson v. Austin,
will generally be limited to freedom from restraint which, while not exceeding the sentence in such an unexpected manner as to give rise to protection by the Due Process Clause of its own force, nonetheless imposes atypical and significant hardship on the inmate in relation to the ordinary incidents of prison life.
Sandin v. Conner,
Plaintiffs argue that they have a liberty interest created by state law, specifically § 99-19-51, and that it prevents the state from executing them using any drugs other than “an ultra short-acting barbiturate or other similar drug” as the first drug in a three-drug cocktail. However, even if the revised lethal injection protocol does not conform to § 99-19-51, “a mere error of state law is not a denial of due process.” Swarthout v. Cooke,
Therefore, in order to establish a liberty interest arising from § 99-19-51, Plaintiffs must show that execution with pentobarbital or midazolam would “impose atypical and significant hardship” on them beyond the ordinary for those facing execution. Sandin,
Here, however, Mississippi’s statutory requirements and the associated lethal in
Even if § 99-19-51 were to create a liberty interest, the right it creates would be subject only to procedural protection. State law is not a source of liberty interests that are substantively protected by the Fourteenth Amendment; rather, it gives rise to interests that are promised procedural protections by the Fourtеenth Amendment. Swarthout v. Cooke,
Our sister circuit has concluded that state post-conviction reliеf petitions satisfy a prisoner’s right to seek proper enforcement of a state’s method-of-execution law. Pavatt v. Jones,
B.
Plaintiffs also argue that Mississippi’s intention to execute them in a manner other than that described by § 99-19-51 “shocks the conscience” and that they are entitled to substantive enforcement of § 99-19-51 regardless of the state post-conviction relief procedures available to them. This argument sounds in substantive due process. According to the Supreme Court, “[t]he touchstone of due process is protection of the individual against arbitrary action of government.” County of Sacramento,
Plaintiffs base their substantive due process argument on Hicks v. Oklahoma and its progeny and argue that execution under the revised protocol “shocks the conscience.” County of Sacramento,
III.
Plaintiffs have not demonstrated a substantial likelihood of success on the merits of their claims because they have not established a liberty interest in the enforcement of § 99-19-51 and because they have not shown that Mississippi’s alleged deviation § 99-1-51 would “shock the conscience.” Therefore, the district court abused its discretion by granting an injunction.
Notes
. Plaintiffs’ petition for panel rehearing is DENIED. No member of the panel nor judge in regular active service of the court having requested that the court be polled on rehearing en banc, Plaintiffs’ petition for rehearing en banc is DENIED.
. We refer to Jordan, Chase, and Loden сollectively as Plaintiffs. Loden is an intervenor but raises claims indistinguishable from those raised by Chase and Jordan.
. The district court has not yet considered the Plaintiffs’ First Amendment access to courts claim, Eighth Amendment cruel and unusual punishment claim, and Fourteenth Amendment notice claim. These claims may be considered in the first instance on remand.
. Mississippi asserts that, as it no longer hаs pentobarbital and is currently unable to obtain more, there is no live controversy regarding pentobarbital and the issue is moot. Because other states retain access to pento-barbital it seems possible that Mississippi could regain access in the future. We are reluctant to conclude the issue is moot because we are not convincеd "subsequent events [have] made it absolutely clear that the allegedly wrongful behavior could not reasonably be expected to recur." Friends of the Earth, Inc. v. Laidlaw Envtl. Servs.,
. A plaintiff can sometimes avoid the jurisdictional bar posed by sovereign immunity by suing a state officer and challenging the actions of that officer as prohibited by federal law and therefore ultra vires. Ex Parte Young,
. The district court did not reach Plaintiffs' remaining claims alleging a violation Plaintiffs’ right to fair notice of Mississippi’s method of execution, alleging a violation of Plaintiffs’ Eighth Amendment rights arising from Mississippi’s failure to use a one-drug protocol, and alleging a violation of Plаintiffs' right of access to courts. Therefore we do not address those claims here. See Sepulvado,
. The district court, having found Plaintiffs were likely to succeed on the merits, concluded without analysis that they satisfied prongs three and four of the test for a preliminary injunction. The Supreme Court requires that, in addition to considering Plaintiffs interests in obtaining an injunction, we also consider the public’s intеrest in the enforcement of state law and the validation of a jury verdict.
