The US Supreme Court on Thursday denied an appeal by the state of Alabama to execute death row prisoner Jeffery Lee using nitrogen gas, letting stand lower court rulings that blocked the method as likely unconstitutional.
Two federal courts had earlier ruled that executing inmates through nitrogen hypoxia—forcing a prisoner to breathe pure nitrogen through a gas mask until suffocation occurs—likely violates the Eighth Amendment's prohibition on cruel and unusual punishment. Alabama appealed those decisions directly to the Supreme Court, filing an emergency order just hours before Lee was scheduled to die at 18:00 local time.
The high court's brief, unsigned order did not provide reasoning for the denial. However, Justices Clarence Thomas, Samuel Alito, and Neil Gorsuch indicated through dissenting statements that they would have granted Alabama's request to proceed with the execution.
Jeffery Lee, 49, has spent more than two decades on Alabama's death row after being convicted of murdering two people during a 1998 pawnshop robbery. A jury originally recommended a life imprisonment sentence, but a judge overturned that verdict and imposed death under a since-abolished judicial override procedure that allowed judges to reject jury sentencing recommendations.
What the Right Is Saying
Alabama Attorney General Steve Marshall called the halted execution a miscarriage of justice for both the state and the families of Lee's victims. He said victims' relatives had prepared to witness what they considered the final act of accountability in the case.
The state's legal team argued that nitrogen hypoxia represents a constitutionally permissible alternative execution method that Alabama has the authority to employ under its own statutes. Marshall stated the state is prepared to pursue all available options to carry out Lee's lawfully imposed sentence.
Conservative legal commentators noted that three sitting justices found sufficient grounds to allow the execution to proceed, suggesting at least some judicial skepticism about the lower courts' constitutional analysis. They argued that states retain significant discretion in determining how to fulfill capital punishment sentences once they are legally authorized.
What the Left Is Saying
Civil rights advocates and death penalty opponents praised the Supreme Court's decision to let the lower court rulings stand. Defense attorneys had argued that nitrogen hypoxia causes inmates to experience severe air hunger, emotional distress, anxiety, and physical discomfort before asphyxiation occurs—effects they characterized as torture incompatible with constitutional standards.
A federal judge issued a permanent injunction against the execution method earlier this week following an April bench trial where experts and witnesses testified about the physiological effects of forced nitrogen inhalation. The ruling reversed an earlier appeals court decision that had allowed Alabama to proceed with the execution.
Death penalty abolition groups pointed to the expert testimony as evidence that states should abandon nitrogen gas as a means of capital punishment, arguing that judicial oversight serves its intended purpose of protecting individuals from government overreach in extreme circumstances.
What the Numbers Show
Jeffery Lee has been on Alabama's death row for 26 years following his 1998 conviction for murdering two people during a pawnshop robbery. The jury initially recommended life imprisonment without parole, but a judge imposed death under the judicial override mechanism that Alabama abolished in 2017.
Federal courts have now blocked nitrogen hypoxia executions in Alabama through permanent injunctions based on testimony describing inmates' likely experiences: severe air hunger, corresponding emotional distress, anxiety, physiological stress, and physical discomfort before death occurs. Three of nine Supreme Court justices indicated they would have reversed the lower courts and allowed Thursday's execution to proceed.
The Bottom Line
The Supreme Court's denial leaves Alabama unable to execute Jeffery Lee using nitrogen gas as currently configured under state law. The state may pursue alternative execution methods or continue legal challenges to the federal injunctions barring nitrogen hypoxia, though any such efforts would face significant procedural hurdles given Thursday's ruling.
For death penalty opponents, the decision represents vindication of judicial review mechanisms designed to prevent government-inflicted suffering. For supporters of capital punishment who view executions as appropriate justice in cases like Lee's double homicide, the blocked execution underscores ongoing tensions between state authority and constitutional limits on punitive methods.
