US appeals court raises concerns about Alabama’s use of nitrogen gas for executions
MONTGOMERY, Ala. (AP) — Alabama’s use of nitrogen gas to put people to death needs more study of whether it violates a constitutional ban on cruel and unusual punishment, a federal appeals court decided Monday.
The state first used nitrogen for capital punishment in 2024, and the ruling could upend Alabama’s next scheduled execution on Thursday. The method involves strapping a respirator to the person’s face and replacing breathable air with pure nitrogen, causing death from lack of oxygen.
The three-judge panel on Monday night reversed a judge’s May finding that the nitrogen method does not violate the U.S. Constitution’s ban on cruel and unusual punishment and remanded the case for additional consideration. The ruling came in a lawsuit filed last year by Jeffery Lee, a man on death row who is scheduled to be executed with nitrogen on Thursday at a south Alabama prison.
The panel stopped short of staying Lee’s planned execution. However, the panel asked the judge to consider whether his proposed alternative of a firing squad was feasible.
