The Supreme Court of the southern US state of Tennessee has temporarily suspended executions pending its ruling on the constitutionality of carrying out the death sentence by a different lethal injection and the electric chair. In a ruling on Friday, the judges suspended three executions scheduled for this year and another for March 2016. The court recently suspended half a dozen executions to hear individual appeals, but the ruling, announced on Monday, paralyses all protocol for executions pending revision, Efe reported.
Tennessee last executed a prisoner in 2009, but since then has had problems sourcing the ingredients for its lethal injections. Responding to these problems, in 2014 the state reinstated the electric chair as an approved alternative method of execution. This approval came ahead of other states including Utah and Oklahoma, which legalised the firing squad and nitrogen suffocation respectively as execution methods. Tennessee, where 69 prisoners remain on death row, last year scheduled 11 executions between mid-2014 and 2016, only to have the schedule suspended in the courts. Two of these prisoners have since died natural deaths, authorities said.
