Durham Test Law and Legal Definition

The Durham test is a principle applied in the U.S. criminal law. According to this principle, an individual accused of a crime is not criminally responsible, if the unlawful act was the product of mental disease or mental defect. This principle was first adopted by the U.S. Court of Appeals for the District of Columbia Circuit in Durham v. United States, 214 F.2d 862 (D.C. Cir. 1954), wherein the standard was set. The Durham test is also known as product test.
