Tennessee halts execution of prisoners until further notice

NASHVILLE, April 13 (UPI) -- The Tennessee Supreme Court has decided to halt all executions of prisoners until further notice.

Four inmates were set to be executed using lethal injection, but the inmates have instigated legal action against the state, calling lethal injection unconstitutional. The executions were originally scheduled between October of 2015 and March of 2016, according to the Washington Post.

No executions will occur until a trial court considers the legal action brought forward by the inmates.

Shortages of the drugs used for executions have halted executions in several states, and the U.S. Supreme Court will consider how lethal injections could go forward. That case will be decided toward the end of this month. Florida, Oklahoma and Alabama are among the states waiting for the Supreme Court's decision.
