There is no statute that requires secre­cy, but it is the posi­tion of the Department gen­er­al­ly that the lethal-injec­tion pro­to­col is con­fi­den­tial and out­side the purview of a pub­lic records request.

Much of the August 2023 pro­to­col release redacts impor­tant infor­ma­tion regard­ing the specifics of the state’s nitro­gen hypox­ia pro­to­col. The state asks spir­i­tu­al advi­sors to sign a waiv­er acknowl­edg­ing the dan­ger present while in the execution chamber.
