Federal Judge Permanently Blocks Nitrogen Hypoxia Executions in Alabama
A federal judge has permanently blocked Alabama from executing death row inmate Jeffery Lee using nitrogen gas, ruling that the method violates the Eighth Amendment's ban on cruel and unusual punishment. U.S. District Judge Emily Marks issued the landmark decision on June 9, 2026, just two days before Lee was scheduled to die by nitrogen hypoxia at Holman Correctional Facility. The ruling marks a dramatic reversal after the same judge had previously found the method constitutional in May.
Alabama pioneered nitrogen gas executions in the United States, first using the method in January 2024 on inmate Kenneth Eugene Smith. Since then, the state has carried out seven nitrogen gas executions, with Louisiana conducting one additional case. The method involves strapping a respirator mask over the inmate's face and replacing breathable air with pure nitrogen, causing death by oxygen deprivation within minutes.
The Jeffery Lee Case: A Jury's Verdict Overruled
Lee, now 49, was convicted of capital murder for the 1998 shooting deaths of Jimmy Ellis and Elaine Thompson during a pawnshop robbery in Orrville, Alabama. A third victim, Helen King, survived her injuries. In 2000, Lee's jury voted 7-5 in favor of life imprisonment without parole, but the presiding judge overrode that recommendation under Alabama's now-abolished judicial override law and imposed a death sentence.
Alabama ended judicial override in 2017, requiring judges to abide by jury sentencing recommendations going forward. However, the change was not made retroactive, leaving Lee and approximately 30 other death row inmates still facing execution under judge-imposed sentences. Lee's case has drawn widespread criticism from advocacy groups, including the Equal Justice Initiative, which notes that the prosecutor in his original trial used all 21 peremptory strikes against Black jurors. Lee, who is Black, has spent over 25 years on death row, where he has become a Kairos ministry leader and assistant chaplain.
Legal Whiplash: From Constitutional to 'Intolerable'
The legal journey of Lee's case illustrates the deep divisions over nitrogen hypoxia. On May 28, 2026, Judge Marks ruled that nitrogen gas executions were constitutional, finding that while inmates likely experience 1-3 minutes of air hunger, this was an 'inescapable consequence of death' rather than constitutionally impermissible pain. However, the 11th U.S. Circuit Court of Appeals reversed that decision on June 9, calling the three-minute window of potential suffering 'intolerable' and finding that the protocol poses a 'substantial risk of serious harm—severe pain over and above death itself.'
Following the appeals court's directive, Judge Marks issued a permanent injunction barring Alabama from using nitrogen gas for executions. The ruling applies specifically to Lee but effectively halts all nitrogen gas executions in the state pending further litigation. Alabama Attorney General Steve Marshall has announced the state will appeal, and the case is expected to reach the U.S. Supreme Court, which previously allowed nitrogen gas executions to proceed.
How Nitrogen Hypoxia Works and Why It's Controversial
Nitrogen hypoxia causes death by replacing oxygen with nitrogen gas, an odorless and colorless substance that makes up 78% of the air humans breathe. When pure nitrogen is administered through a sealed mask, the body's cells and organs begin shutting down from oxygen deprivation. Proponents argue it is more humane than lethal injection, as it avoids the complications of finding intravenous access and sourcing execution drugs that pharmaceutical companies refuse to supply.
Critics, however, contend that the method causes severe suffering. Witnesses to Kenneth Smith's 2024 execution reported that he appeared conscious for several minutes, shaking and writhing on the gurney before taking deep, labored breaths. Medical experts testified that inmates likely experience intense air hunger—a feeling of suffocation—for one to three minutes while still conscious. Veterinarians have refused to use nitrogen asphyxiation for animal euthanasia due to its distressing effects. The United Nations has warned that the method could constitute torture under international law.

What This Ruling Means for Capital Punishment in Alabama
Alabama remains one of 20 states that still carry out executions, and it has the highest per capita death sentencing rate in the nation. The state has two other authorized execution methods: lethal injection and the electric chair. Judge Marks noted that Alabama could still execute Lee using either method, or switch to Lee's preferred alternative—a firing squad, which is not currently authorized in Alabama but has been proposed in other states.
The ruling does not abolish the death penalty in Alabama, but it deals a significant blow to the state's efforts to expand nitrogen gas as an execution method. Alabama, Oklahoma, and Mississippi are the only states that have approved nitrogen hypoxia for executions. The decision also raises questions about the future of the seven inmates currently on Alabama's death row who have elected nitrogen hypoxia as their preferred method.
Activists have urged Governor Kay Ivey to commute Lee's sentence to life without parole, arguing that respecting the jury's original verdict would align with current Alabama law. Former Alabama Chief Justice Drayton Nabers Jr. has publicly urged clemency, citing conservative principles of limited government and respect for the jury system. The state's clemency process remains an option, though the governor has not indicated any willingness to intervene.
The implications extend beyond Alabama. As the first federal court to permanently block nitrogen gas executions, this ruling could influence similar challenges in Louisiana and other states considering the method. Legal experts suggest the Supreme Court's stance on execution methods will ultimately determine the fate of nitrogen hypoxia nationwide.
Frequently Asked Questions
What is nitrogen gas execution?
Nitrogen gas execution, also known as nitrogen hypoxia, is a method of capital punishment where a gas mask is placed over the inmate's face and pure nitrogen is administered, causing death by oxygen deprivation. The inmate is expected to lose consciousness within 60-75 seconds and die within minutes.
Why did the judge rule it unconstitutional?
Judge Marks ruled that Alabama's nitrogen gas protocol violates the Eighth Amendment because it creates a substantial risk of severe pain—specifically, intense air hunger (suffocation) lasting 1-3 minutes while the inmate remains conscious. The 11th Circuit called this time frame 'intolerable' under constitutional standards.
How many people have been executed by nitrogen gas in the US?
As of June 2026, eight people have been executed by nitrogen gas in the United States: seven in Alabama (starting with Kenneth Smith in January 2024) and one in Louisiana. Alabama was the first state to use the method.
What happens to Jeffery Lee now?
Lee's execution by nitrogen gas has been permanently blocked. Alabama can still pursue execution by lethal injection or the electric chair. Lee's legal team is seeking to have his sentence commuted to life without parole, as originally recommended by his jury. The state is appealing the ruling, and the case may reach the U.S. Supreme Court.
Which states allow nitrogen gas executions?
Only three states have approved nitrogen hypoxia for executions: Alabama, Oklahoma, and Mississippi. Alabama is the only state that has actually used the method. Other states, including Louisiana, have conducted executions using nitrogen gas following Alabama's protocol.
