Arizona, the U.S. Supreme Court was faced with two main questions: Does Arizona’s insanity defense statute, with its abridged M’Naughten standard, violate the Fourteenth Amendment? And does Arizona case law, with its complete prohibition on the use of mental disease or defect evidence to combat required mens rea elements of a crime, violate due process? In a six–three decision, the Court answered both of these questions in the negative.
