PIERCE, Justice, for the Court:
¶ 1. Three death-row inmates, Robert Simon, Rodney Gray, and Benny Stevens, along with the groups, Mississippians Educating for Smart Justice and Mississippi CURE, Inc. (collectively, the petitioners) filed a complaint in the Hinds County Circuit Court, seeking a writ of mandamus, injunctive relief, and/or a declaratory judgment against the Mississippi Department of Corrections (MDOC).
¶ 2. Executions are governed by Mississippi Code Sections 99-19-51 through 99-19-61 (Rev.2007). Section 99-19-51 states:
Pursuant to Section 99-19-53, the state executioner or duly authorized representative shall inflict the punishment of death, and all duties and necessary acts pertaining to the execution shall be performed by the commissioner of corrections, except where such duties and actions are vested in the state executioner.
¶ 3. Prior to March 2011, the execution protocol implemented by the commissioner for carrying out the method of death prescribed by Section 99-19-51 had called for injection of three drugs: (1) sodium pentothal (also known as sodium thiopental), an anesthetic; (2) pavulon (also known as pancuroniam bromide), a paralytic agent; and (3) potassium chloride, which stops the heart. In 2009, Hospira, Inc., the sole United States manufacturer of the drug sodium thiopental, announced that it planned to stop producing sodium thiopental, because the company did not want the drug used in executions. A nationwide shortage of the drug ensued, and a number of states began substituting pentobarbital for sodium thiopental in their respective states execution protocol. See e.g. Jackson v. Danberg, 656 F.3d 157, 160 (3rd Cir. 2011) (noting that "[d]ue to a nationwide shortage of sodium thiopental, Delaware, along with a number of other states, revised its protocol to allow for the use of an alternative barbiturate, pentobarbital"); see also Valle v. Singer, 655 F.3d 1223, 1229 n. 5 (11th Cir.2011) (noting Florida's recent replacement, along with Georgia and Alabama).
¶ 4. On March 29, 2011, the MDOC issued a revised execution protocol, allowing the use of pentobarbital, "[i]n the event of an unavailability of a sufficient quantity of sodium pentothal from available sources...." The petitioners thereafter
¶ 5. The petitioners argue on appeal that the circuit court erroneously held that the MDOC's execution protocol qualifies for the MAPL's exemption for rules. They contend the circuit court gave an overly broad reading of the statute, which, the petitioners maintain, is narrowly drawn and, by its plain terms, applies only to agency rules that satisfy two criteria: The rule (1) must directly relate only to inmates and (2) must have been adopted by an individual correctional facility. According to the petitioners, the MDOC's execution protocol relates to far more persons than inmates alone, as it governs the conduct of twenty-nine categories of MDOC personnel, outside witnesses to the execution, and even members of the media. They further contend that the execution protocol is an agency-wide policy, promulgated by the MDOC itself, not by a specific prison facility in Mississippi.
¶ 6. This Court reviews questions of statutory interpretation de novo. Our duty is "to neither broaden nor restrict the legislative act" when passing upon such questions. Miss. Dep't of Transp. v. Allred, 928 So.2d 152, 156 (Miss.2006). We held in Green v. Cleary Water, Sewer & Fire Dist., 910 So.2d 1022, 1027 (Miss. 2005), that "courts cannot restrict or enlarge the meaning of an unambiguous statute." And we reiterated in Allred:
Allred, 928 So.2d at 154 (quoting City of Natchez v. Sullivan, 612 So.2d 1087, 1089 (Miss.1992)).
¶ 7. As the State points out, the claim before us is not a novel one. A similar question was presented to the Missouri Supreme Court in Middleton v. Missouri Department of Corrections, 278 S.W.3d 193, 195 (Mo.2009). There, the Missouri Supreme Court was asked to declare whether the Missouri Department of Corrections' newly adopted execution protocol was void because the department had failed to undertake notice-and-comment rulemaking as outlined by the Missouri Administrative Procedures Act (MAPA). Id. at 195. Similar to the exemption provision found in the MAPL, the MAPA provides that a "rule" does not include any
Id.
¶ 8. We agree with the Missouri Supreme Court's rationale. Here, the fact that the execution protocol contains provisions pertaining to individuals other than a condemned inmate does not lead us to a conclusion that the drug protocol falls within the strictures of the MAPL. Indeed, no serious contention can be made that the MDOC's drug protocol falls outside Section 25-43-1.102(i)(ii)(6), as every intricate detail of the protocol applies directly to death-row inmates under any ordinary meaning of the exemption language set forth by that section.
¶ 9. As mentioned, "[a]ll duties and necessary acts pertaining to the execution of a convict shall be performed by the commissioner of corrections...." Miss.Code Ann. § 99-19-53 (Rev.2007). Section 99-19-55 specifies, in part that the commissioner:
Miss.Code Ann. § 99-19-55 (Rev.2007). The section also provides that the execution shall take place at 6:00 p.m., or as soon as possible thereafter within the next twenty-four hours, at an appropriate place designated by the commissioner on the premises of the state penitentiary at Parchman, Mississippi. The execution
¶ 10. Accordingly, we find that the MDOC execution protocol is a "regulation or statement" related only to inmates of the MDOC and is therefore exempt from the provisions of the MAPL. The protocol is an internal policy concerning lethal injections and the manner in which executions are carried out and is therefore not subject to the notice and comment requirements of the MAPL. Thus, this Court affirms the circuit court's judgment.
¶ 11. The circuit court's denial of the petitioners' complaint for a declaratory judgment, writ of mandamus, and injunction is affirmed.
