Arizona Governor Signs Law Prohibiting the Execution of the Mentally Retarded 

On April 26, 2001, Arizona Governor Jane Hull signed legislation to ban the state from seeking the death penalty for persons with mental retardation.  The legislation also prohibits the execution of defendants with mental retardation who are already on death row.  Arizona is now the 14th state to forbid such executions.
