A group of Republicans are introducing the following bill:

" The Congress may, if two thirds of each House agree, reverse a judgment of the United States Supreme Court--
  (1) if that judgment is handed down after the date of the enactment of this Act; and
  (2) to the extent that judgment concerns the constitutionality of an Act of Congress."

Any guesses as to motivation for this bill?
