From the National Industrial Recovery Act of 1933, eventually struck down by the Supreme Court:
Whenever the President shall find that destructive wage or price cutting or other activities contrary to the policy of this title are being practiced in any trade or industry or any subdivision thereof, and, after such public notice and hearing as he shall specify, shall find it essential to license business enterprises in order to make effective a code of fair competition or an agreement under this title or otherwise to effectuate the policy of this title, and shall publicly so announce, no person shall, after a date fixed in such announcement, engage in or carry on any business, in or affecting interstate or foreign commerce, specified in such announcement, unless he shall have first obtained a license issued pursuant to such regulations as the President shall prescribe. The President may suspend or revoke any such license, after due notice and opportunity for hear ing, for violations of the terms or conditions thereof. Any order of the President suspending or revoking any such license shall be final if in accordance with law.
With this law, all commerce was to be conducted only at the President's pleasure. The law also instituted code authorities, modeled on Mussolini's economic system, that would set prices, wages, production quotas and nearly every other business practice in an industry. To some extent, I would argue that the recent health care bill is the first modern American code authority.
