CourtDiscuss the following cases and the impact they had on expert witness testimony: 1.Frye v. United States 2.Daubert v. Merrell Dow Pharmaceuticals, Inc. 3.Kuhmo Tires Co. v. Carmichael
My favorite of these is Frye v. United States. Polygraph tests are given by experts who can monitor a suspect's truthfulness or deceit. The court ruled that expert testimony could be used to explain the results of the test. Now, courts allow expert testimony but not polygraph results.
