WASHINGTON (AP) — The Supreme Court is sending a message to states that want to continue to carry out the death penalty: Inmates must be allowed to have a spiritual adviser by their side as they are executed.

The high court around midnight Thursday declined to let Alabama proceed with the lethal injection of Willie B. Smith III. Smith had objected to Alabama’s policy that his pastor would have had to observe his execution from an adjacent room rather than the death chamber itself.

The order from the high court follows two years in which inmates saw some rare success in bringing challenges based on the issue of chaplains in the death chamber. This time, liberal and conservative members of the court normally in disagreement over death penalty issues found common ground not on the death penalty itself but on the issue of religious freedom and how the death penalty is carried out.

Justice Brett Kavanaugh, one of three justices who said they would have let Smith’s execution go forward, said Alabama’s policy applies equally to all inmates and serves a state interest in ensuring safety and security. But he said it was apparent that his colleagues who disagreed were providing a path for states to follow.

States that want to avoid months or years of litigation over the presence of spiritual advisers “should figure out a way to allow spiritual advisors into the execution room, as other States and the Federal Government have done,” he wrote in a dissent joined by Chief Justice John Roberts. Justice Clarence Thomas also would have allowed the execution of Smith, who was sentenced to die for the 1991 murder of 22-year-old Sharma Ruth Johnson in Birmingham.

Alabama had up until 2019 allowed a Christian prison chaplain employed by the state to be physically present in the execution chamber if requested by the inmate, but the state changed its policy in response to two earlier Supreme Court cases.

Robert Dunham, the executive director of the Death Penalty Information Center, says the court’s order will most clearly affect states in the Deep South that have active execution chambers. Dunham said most state execution protocols, which set who is present in the death chamber, do not mention spiritual advisers. For most of the modern history of the U.S. death penalty since the 1970s, spiritual advisers have not been present in execution chambers, he said.

The federal government, which under President Donald Trump resumed federal executions following a 17-year hiatus and carried out 13 executions, allowed a spiritual adviser to be present in the death chamber. The Biden administration is still weighing how it will proceed in death penalty cases.

The court’s order in Smith’s case contained only statements from Kavanaugh and Justice Elena Kagan.

“Willie Smith is sentenced to death, and his last wish is to have his pastor with him as he dies,” Kagan wrote for herself and liberal justices Sonia Sotomayor and Stephen Breyer, as well as conservative Amy Coney Barrett. Kagan added: “Alabama has not carried its burden of showing that the exclusion of all clergy members from the execution chamber is necessary to ensure prison security.”
