A federal district judge has enjoined executions under Tennessee's new injection protocol. The decision in Harbison v. Little is here. On a quick read, the main reason seems to be the lack of an unconsciousness confirmation step in the protocol. The alternative of a single-drug protocol is also discussed.

Update: Erik Schelzig has this story for AP. The plaintiff, Edward "Harbison was scheduled to be executed Sept. 19 for beating an elderly woman to death during a burglary in 1983."
