Notice that it is consistent with some versions of originalism that the correct application of constitutional norms may be different from the way in which the Constitution was originally intended and expected to apply. In one kind of case, the correct application of the Constitution changes over time as a result of changes in circumstances. The commerce clause, for example, specifies that Congress shall have power over “commerce among the several states” (U.S. Constitution, Article I, section 8, clause 3). If the relevant original aspect of the Constitution is the meaning of the words or the framers’ intention about what legal rule to adopt (on such intentions, see section 4.1), then, without any change in constitutional law, changes in the country’s economy may have the effect that types of businesses that were formerly not within the scope of Congress’s power over interstate commerce may now be within the scope of the power. (Greenberg and Litman 1998).
