How Durham v. United States applies in Michigan: state-specific rules, key cases, and bar exam notes for Criminal Law.
Michigan generally follows a more traditional approach to mental illness defenses compared to the broader 'product test' from Durham. Michigan law emphasizes a clearer distinction between legal insanity under MCL 768.36 and the standards set out in Durham.
In Michigan, the legal standard for insanity focuses on whether the defendant, due to mental illness, lacked substantial capacity to appreciate the nature of the act or to distinguish right from wrong.
The Michigan Supreme Court clarified the standard for legal insanity, rejecting the broader interpretations found in Durham.
The court reaffirmed that the Michigan standard requires a defendant to demonstrate significant impairment in understanding conduct due to mental illness for an insanity defense.
The court upheld that the burden of proof for proving insanity lies with the defendant, aligning with established Michigan principles.
Michigan's approach to the insanity defense is more stringent than the federal standard established in Durham v. United States. Unlike the Durham ruling, which allowed for a broader interpretation of mental illness as a defense, Michigan requires a demonstrable inability to differentiate right from wrong based on established psychiatric evaluations.
Understanding the difference between Michigan's insanity defense and the standards set in federal cases like Durham is crucial for the Michigan bar exam.
