NCAA, a case in which New Jersey repealed laws criminalizing sports betting while a federal law prevented states providing that states may not "sponsor, operate, advertise, promote, license, or authorize by law or compact" sports gambling.[12][13][14] The court rejected the respondents' argument that the anti-authorization provision was a valid preemption of state law under the Supremacy Clause of the U.S. Constitution.[15] The Supremacy Clause, the court pointed out, "is not an independent grant of legislative power to Congress" but "[i]nstead, it simply provides a rule of decision."[16] For a federal provision to validly preempt state law, "it must represent the exercise of a power conferred on Congress by the Constitution[,] pointing to the Supremacy Clause will not do",[17] and "since the Constitution confers upon Congress the power to regulate individuals, not States, [the] provision at issue must be best read as one that regulates private actors."[18] ./cache/en-wikipedia-org-4847.html ./txt/en-wikipedia-org-4847.txt
