United States. Congress, Abridgment of the Debates of Congress…
“ It is not in our power to guard against a repeal. Our acts are not like those of the Medes and Persians, unalterable. A repeal is a thing against which no provision can be made. If that is an objection, it holds good against any law that can be passed. If those States that may have a superiority in Congress at a future day will pay no respect to the acts of their predecessors, or to the public good, there is no power to compel them. ”
