Tennessee can now use the electric chair in the event that its prisons are unable to obtain lethal injection drugs — a recent problem in some states that employ the death penalty.

Republican Gov. Bill Haslam signed a bill into law Thursday allowing the state to electrocute death row inmates as a backup to lethal injection, still the main method of execution in the United States. The move makes Tennessee the first state to enact a law to reintroduce electrocution without giving prisoners a say, the Associated Press reported.
