Supreme Court declines to let Alabama move forward with nitrogen gas execution

TL;DR

  • The Supreme Court refused to allow Alabama to proceed with the scheduled execution of Jeffrey Lee using nitrogen hypoxia.
  • Federal courts had previously ruled Alabama's nitrogen hypoxia method unconstitutional.
  • Lee's legal team argued the method constitutes cruel and unusual punishment.
  • Alabama's Attorney General petitioned the Supreme Court to reverse the federal judge's ban on the nitrogen hypoxia protocol.
  • The state intends to continue defending its execution method, which has been used in several other executions in the U.S., though witnesses have reported signs of suffering.
  • Lee was sentenced to death for a 1998 robbery and double murder, but the jury initially voted for a life sentence.
