Washington ? Hours after staying the execution of an inmate who was already strapped to a gurney, the Supreme Court said Wednesday it would hear arguments from the man who claims the drug cocktail used in lethal injections can cause excruciating pain.

The Supreme Court has never found a specific form of execution to be cruel and unusual punishment, and the latest case from Florida does not give court members that opportunity. The justices will, however, spell out what options are available to inmates with last-minute challenges to the way they will be put to death.

Florida inmate Clarence Hill, who filed the appeal, had been strapped to a gurney with intravenous lines running into his arms Tuesday night when he won a temporary Supreme Court stay, Hill’s lawyer said. The stay was signed by Justice Anthony M. Kennedy.
