What is this law that originally comprised seven articles that entrench the doctrine of the separation of powers in the United States, whose clause was reaffirmed by the decision from Lambert v. Yellowley?
Lambert v. Yellowley Lambert v. Yellowley, 272 U.S. 581 (1926) , was a decision by the Supreme Court of the United States that reaffirmed the National Prohibition Act's limitation on the dispensation of alcoholic medicines. The five-to-four decision, written by Justice Louis D. Brandeis, affirmed the dismissal of a suit in which New York City physician Samuel Lambert sought to prevent Edward Yellowley, the acting federal prohibition director, from enforcing the Prohibition Act so as to preclude him from prescribing alcoholic medicines. The decision affirmed the police powers of the individual states, as well as the power of the Necessary and Proper Clause of the United States Constitution, which was cited in upholding the Prohibition Act's limitations as a necessary and proper implementation of the Eighteenth Amendment to the United States Constitution.
