Six death row inmates, including one scheduled to die July 23, sued the state today in federal court, alleging the secrecy surrounding the lethal drugs to be used in executions violates their First Amendment rights.

The U.S. Supreme Court recently refused to hear four Arizona capital cases, opening the door for a spate of executions in the coming months.

A state appellate court on Thursday rejected a challenge to the constitutionality of Arizona's injection execution law but warned the state that last-minute changes in execution procedures are a problem.

Taking a cue from a 9th U.S. Circuit Court of Appeals judge, a First Amendment group is asking a federal judge to let the public view more of an execution than what is permitted.
