Are both Diamond v. Chakrabarty and Gates v. Collier United States Supreme Court cases?
Diamond v. Chakrabarty Diamond v. Chakrabarty, 447 U.S. 303 (1980), was a United States Supreme Court case dealing with whether genetically modified organisms can be patented.
Heath v. Alabama Heath v. Alabama, 474 U.S. 82 (1985), is a case in which the United States Supreme Court ruled that, because of the doctrine of "dual sovereignty" (the concept that the United States and each state possess sovereignty – a consequence of federalism), the double jeopardy clause of the Fifth Amendment to the Constitution does not prohibit one state from prosecuting and punishing somebody for an act of which he had already been convicted of and sentenced for in another state.
