Opinion of the Court

evening, the execution team spent nearly an hour making at least one dozen attempts to establish intravenous (IV) access to Lockett’s cardiovascular system, including at his arms and elsewhere on his body. The team eventually believed that it had established intravenous access through Lockett’s right femoral vein, and it covered the injection access point with a sheet, in part to preserve Lockett’s dignity during the execution. After the team administered the midazolam and a physician determined that Lockett was unconscious, the team next administered the paralytic agent (vecuronium bromide) and most of the potassium chloride. Lockett began to move and speak, at which point the physician lifted the sheet and determined that the IV had “infiltrated,” which means that “the IV fluid, rather than entering Lockett’s blood stream, had leaked into the tissue surrounding the IV access point.” Warner v. Gross, 776 F. 3d 721, 725 (CA10 2015) (case below). The execution team stopped administering the remaining potassium chloride and terminated the execution about 33 minutes after the midazolam was first injected. About 10 minutes later, Lockett was pronounced dead. An investigation into the Lockett execution concluded that “the viability of the IV access point was the single greatest factor that contributed to the difficulty in administering the execution drugs.” App. 398. The investigation, which took five months to complete, recommended several changes to Oklahoma’s execution protocol, and Oklahoma adopted a new protocol with an effective date of September 30, 2014. That protocol allows the Oklahoma Department of Corrections to choose among four different drug combinations. The option that Oklahoma plans to use to execute petitioners calls for the administration of 500 milligrams of midazolam followed by a paralytic agent
