How about the Constitution? You remember, the law of the land, that was written to limit the powers of the federal government? And specifically the Ammendment being discussed in this thread, the 10th: It means, literally: "The powers not given to the federal government by the Constitution, are given to the States, or the people." The government has no power to act on laws that are not specifically within the constitution, plain and simple. They have no right to enact any federal laws outside of the scope granted to them BY THE CONSTITUTION.
