A federal appeals court is hearing arguments over the constitutionality of Ohio's lethal injection process as the state tries to start carrying out executions once again.
State attorneys say they have provided plenty of evidence to show that the contested first drug in Ohio's three-drug method will put inmates into a deep state of unconsciousness.
The state also argues that the U.S. Supreme Court upheld the use of that drug, midazolam, in a case out of Oklahoma in 2015.
Lawyers for death row inmates are challenging the effectiveness of midazolam.
The 6th U.S. Circuit Court of Appeals in Cincinnati scheduled arguments for Tuesday. Arguments were previously set for late February, but were delayed.
