Study notes for Durham v. United States: professor notes, cold call prep, exam angles, and memory aids.

The court adopted the standard that criminal responsibility should be based on whether the defendant's act was the product of mental disease or defect.
Professor Notes

In Durham v. United States, the D.C. Circuit rejected the traditional M'Naghten test for insanity, which assessed whether a defendant could distinguish right from wrong at the time of the crime. Instead, the court adopted a more flexible standard, focusing on whether a defendant's unlawful act was the product of mental illness. This shift reflects a significant evolution in how jurisdictions can approach the intersection of mental health and criminal responsibility, emphasizing the importance of understanding the mental state of the defendant in relation to the crime committed.

The court highlighted the inadequacies of the traditional tests in addressing cases involving mental illness. They pointed out that it can be overly simplistic to assess culpability based solely on the ability to recognize right from wrong, particularly in individuals with complex psychological conditions. This decision not only reversed Durham's conviction but also set a precedent that allowed for more comprehensive expert psychiatric testimony in future cases, which could better inform juries of a defendant's mental state.
