A.L.A. Schechter Poultry Corp. v. United States, 295 U.S. 495 (1935), was a decision by the Supreme Court of the United States that invalidated regulations of the poultry industry according to the nondelegation doctrine and as an invalid use of Congress' power under the Commerce Clause. This was a unanimous decision that rendered parts of the National Industrial Recovery Act of 1933 (NIRA), a main component of President Franklin D. Roosevelt's New Deal, unconstitutional. The case from which the ruling stemmed was nicknamed the "Sick Chicken Case".
