Which program was found unconstitutional under the new deal AAA CCC WPA NRA?

The National Recovery Administration (NRA) was found unconstitutional under the New Deal. In 1935, the Supreme Court ruled in the case of Schechter Poultry Corp. v. United States that the NRA's codes of fair competition violated the non-delegation doctrine and exceeded Congress's powers to regulate interstate commerce. This decision effectively dismantled the NRA, highlighting the limits of federal power in economic regulation during that era.
