Numerous scholars (including Koch and Ammon) have noted that Madison had the words "void, and of no force or effect" excised from the Virginia Resolutions before adoption. Madison later explained that he did this because an individual state does not have the right to declare a federal law null and void. Rather, Madison explained that "interposition" involved a collective action of the states, not a refusal by an individual state to enforce federal law, and that the deletion of the words "void, and of no force or effect" was intended to make clear that no individual state could nullify federal law.
