"An unconstitutional law cannot operate to supersede any existing valid law. Indeed, insofar as a statute runs counter to the fundamental law of the lend, it is superseded hereby. No one Is bound to obey an unconstitutional law and no courts are bound to enforce it." - 16 American Jurisprudence 2d, Sec 177 late 2d, Sec 256

Plus, this has already been found unconstitutional[1], but that decision was kept secret, cause, y'know... CLASSIFIED.
