MEMORANDUM OPINION AND ORDER

Plaintiff1 and Intervenors2 (“Plaintiffs”) are inmates on death row awaiting execution by the State of Mississippi. They filed this § 19833 lawsuit challenging the constitutionality of Mississippi’s method of execution. Defendants Burl Cain, Marc McClure, the Mississippi State Executioner, and Unknown Executioners (“the State”) filed a Motion for Consolidation [333] of this case with another § 1983 case, Crawford v. Cain, No. 3:25-CV-479-DPJ-ASH. For the reasons provided below, the Court denies the motion.

1 Richard Jordan (executed) and Ricky Chase were the original named Plaintiffs in this case.

2 Robert Simon, Thomas Edwin Loden, Jr. (executed), and Roger Eric Thorson intervened.

3 See 42 U.S.C. § 1983 (providing a civil action for deprivation of rights secured under federal law). I. BACKGROUND4 Plaintiffs are inmates on death row awaiting execution by the State of Mississippi. They claim that Mississippi’s method of execution violates the Eighth Amendment’s prohibition of cruel and unusual punishment.5 Defendants are the Commissioner of the Mississippi Department of

Corrections (“MDOC”), the Superintendent of the Mississippi State Penitentiary, the Mississippi State Executioner, and Unknown Executioners. When Plaintiffs initiated this lawsuit, Mississippi law provided that those condemned to death should be executed 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.” 2016 Miss. Laws Ch. 452. The Mississippi legislature amended this statute in 2022. Its current version permits the State to choose among four different methods of execution: “(a) intravenous injection of a substance or substances in a lethal quantity into the body; (b) nitrogen hypoxia; (c) electrocution; or (d) firing squad, until death is pronounced . . . .” MISS. CODE ANN. § 99-19-51(1)6. Mississippi’s current lethal injection protocol requires a series of three injections: an

anesthetic to render the prisoner unconscious; a paralytic agent; and potassium chloride to stop the prisoner’s heart. See Ex. 1a to Mot. for P.I. [310-2], at 6-10.7 The protocol specifies that MDOC

4 The Court incorporates its discussion of the background of this case from its Memorandum Opinion and Order [277] entered December 7, 2022, Jordan v. Cain, No. 3:15-CV-295-HTW-LGI, 2022 WL 17543344, at *3-*6 (S.D. Miss. Dec. 7, 2022); its Memorandum Opinion and Order [327] entered June 20, 2025, Jordan v. Cain, No. 3:15-CV-295- HTW-LGI, 2025 WL 1728266, at *1-*5 (S.D. Miss. June 20, 2025); and its Memorandum Opinion and Order [332] entered August 11, 2025, Chase v. Cain, No. 3:15-CV-295-HTW-LGI, 2025 WL 2313223, at *1-5 (S.D. Miss. Aug. 11, 2025).

5 See U.S. CONST. amend. VIII (“Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.”).

6 Historically and currently, the primary statute governing the methodologies and mechanics of capital punishemtn in Mississippi is Miss. Code Ann. § 99-19-51. Prior execution methodologies under Miss. Code Ann § 99-19-51 included hanging and lethal gas/cyanide gas.

7 The record contains multiple versions of MDOC’s “Capital Punishment Procedures.” See Exs. 1a, 1b, 1c, 1d to Mot. for P.I. [310-2, 310-3, 310-4, 310-5]. During this litigation, Plaintiffs informed the Court that MDOC had revised its personnel first must establish an intravenous (“IV”) in each of the inmate’s arms, with one serving as a contingency in case of a malfunction with the other IV. Id. at 9. Sodium pentothal is to be the first injection. If that drug is not available, MDOC must use pentobarbital. Id. at 6. If pentobarbital is not available, MDOC must use 500 mg of midazolam. Id. Four minutes after the first injection

is given, MDOC personnel must determine whether the inmate is unconscious and confirm that the IV line is still functioning properly. Id. at 9-10. If the inmate is still conscious, the MDOC Commissioner decides whether to start the execution over or stop it, but the protocol does not provide the criteria to be applied in making this determination.8 Id. at 10. If the inmate is rendered unconscious, the execution team administers the second injection – pavulon. Id. at 6. If pavulon is not available, either vecuronium bromide or rocuronium bromide must be used. Id. at 7. The last injection is potassium chloride. Id. Throughout the entire execution process, MDOC personnel are required “continually [to] monitor the inmate using all available means to ensure that the inmate remains unconscious and that there are no complications.” Id. at 10.

Plaintiffs’ Amended Complaint [50] asserts five causes of action. See Amended Complaint [50], at 39-55. The Intervenor Complaint [208] relies upon these same five causes. See Intervenor Complaint [208], at 28-40.

“Capital Punishment Procedures” on three separate occasions since 2017. The Court examined the various versions of the execution procedures and discerned no changes material to Plaintiffs’ claims as pleaded in the First Amended Complaint [50]. Likewise, Plaintiffs have not argued any material differences between them; rather, Plaintiffs argue that the procedures are all constitutionally deficient because they employ a three-drug lethal injection protocol.

8 This Court, in its Memorandum Opinion and Order [327] of June 20, 2025, modified the protocol by ordering the State to halt the execution and notify this Court if the consciousness check reveals that the inmate remains conscious/sensate after the first dose of midazolam. Jordan, 2025 WL 1728266 at *16. If the consciousness check reveals that the inmate is unresponsive, the execution may continue. Id. In Count IA, Plaintiffs claim that Defendants’ use of compounded pentobarbital as the anesthetic in a three-drug lethal injection protocol violates their right to be free from cruel and unusual punishment under the United States9 and Mississippi10 Constitutions. See Amended Complaint [50], at 39-43.

In Count IB, Plaintiffs claim that Defendants’ use of midazolam as the anesthetic in a three- drug lethal injection protocol violates Plaintiffs’ right to be free from cruel and unusual punishment under the United States and Mississippi Constitutions. Id. at 43-46. In Count II, Plaintiffs claim that Defendants’ failure to use an ultra short-acting barbiturate or other similar drug as the anesthetic in a three-drug lethal injection protocol violates Plaintiffs’ right to be free from cruel and unusual punishment under the United States Constitution. Id. at 46- 49. In Count III, Plaintiffs claim that Defendants’ continued use of a three-drug lethal injection protocol violates their right to be free from cruel and unusual punishment under the United States and Mississippi Constitutions. Id. at 49-52.

In Count IV, Plaintiffs claim that Defendants’ use of undisclosed compounds or ingredients in the lethal injection protocol violates Plaintiffs’ right to notice of the method of execution under the United States and Mississippi Constitutions.
