I'm guessing Amendment Thirteen to the Constitution:

Section. 1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.

Section. 2. Congress shall have power to enforce this article by appropriate legislation.

Thanks for the information. I wasn't doubting that a law or amendment had been passed, I just couldn't recall what it was. You cleared up my confusion on the subject.
