An Oklahoma judge has struck down a law that hides information on the drugs used in lethal injections. Two death row prisoners had sued the state to disclose the source of the drugs to be used in their executions. On Wednesday, District Court Judge Patricia Parrish ruled Oklahoma has violated the Constitution by failing to disclose the name of the drug supplier, the combination of chemicals and the dosages used in executions. The ruling could delay executions in other states where prisoners are challenging similar laws.
