Decision

Where a U.S. District Court in the Ninth Circuit inquires into the mental capacity of a defendant to stand trial, it also must conduct an inquiry into that defendant's mental capacity to plead guilty. Furthermore, when a questionably competent defendant pleads guilty, the standard for determining competency is higher than when the court is determining a defendant's mental capacity to stand trial.
