Supreme Court rulings on death penalty cases in Alabama.

The U.S. Supreme Court rejected the Alabama attorney general's request to review an 11th U.S. Circuit Court of Appeals decision regarding inmate Kenneth Eugene Smith, who argues he should be put to death by nitrogen hypoxia when he is ultimately executed. Alabama has authorized nitrogen hypoxia as an execution method but no state has attempted to use the untested method to put an inmate to death. Smith was scheduled to be put to death by lethal injection on Nov. 17, 2022, for the 1988 murder-for-hire slaying of a preacher's wife.
