An Alabama inmate would be the test subject for an "experimental" execution method of nitrogen hypoxia, his lawyers argued, as they asked judges to deny the state's request to carry out his death sentence using the new method.
In a Friday court filing, attorneys forasked the Alabama Supreme Court to reject the state attorney general's request to set an execution date for Smith using the proposed new execution method. Nitrogen gas is authorized as an execution method in three states but it has never been used to put an inmate to death.
Smith's attorneys argued the state has disclosed little information about how nitrogen executions would work, releasing only a redacted copy of the proposed protocol.
"The state seeks to make Mr. Smith the test subject for the first ever attempted execution by an untested and only recently released protocol for executing condemned people by the novel method of nitrogen hypoxia," Smith's attorneys wrote.
Under the proposed method, hypoxia would be caused by forcing the inmate to breathe only nitrogen, depriving them of oxygen needed to maintain bodily functions and causing them to die. Nitrogen makes up 78% of the air inhaled by humans and is harmless when inhaled with oxygen. While proponents of the new method have theorized it would be painless, opponents have likened it to human experimentation.
The lawyers said Smith "already has been put through one failed execution attempt" in November when the state tried to put him to death via lethal injection. The Alabama Department of Corrections called off the execution when the execution team could not get the required two intravenous lines connected to Smith.
His attorneys said Smith has ongoing appeals and accused the state of trying to move Smith to "the front of the line" ahead of other inmates in order to moot Smith's lawsuit challenging lethal injection procedures.
Alabama, but the state has not attempted to use it until now to carry out a death sentence. Oklahoma and Mississippi have also authorized nitrogen hypoxia, but have not used it.
Trip Pittman, the former Alabama state senator who proposed the new execution method, has disputed criticism that the method is experimental. He said that while no state has carried out a death sentence with nitrogen, people have died by breathing nitrogen during industrial accidents and suicide attempts, so the effects are known.
Smith was convicted in thein Alabama's Colbert County.
Prosecutors said Smith was one of two men who were each paid $1,000 to kill Sennett on behalf of her husband who was deeply in debt and wanted to collect on insurance. Charles Sennett, the victim's husband and a Church of Christ pastor, killed himself when the investigation began to focus on him as a possible suspect, according to court documents.
John Forrest Parker, the other man that prosecutors said was paid to kill Elizabeth Sennett, was executed in 2010.
Alabama has had some issues carrying out executions in recent years.
In September 2022, Alabamabecause of difficulty accessing the inmate's veins. Alabama Corrections Commissioner John Hamm told reporters that "accessing the veins was taking a little bit longer than we anticipated" and the state did not have sufficient time to get the execution underway by a midnight deadline.
That was at least the third time Alabama has acknowledged problems with venous access during a lethal injection. The state's Hall's family had opposed James' execution.for the 1994 murder of Faith Hall took more than three hours to get underway. CBS affiliate WIAT-TV reported
And, in 2018, Alabamaafter being unable to establish an intravenous line.
According to the Death Penalty Information Center, Alabama has 167 inmates on death row.
