What argument was Oliver Wendell Holmes making in this quotation about how the federal system works? "I do not think the United States would come to an end if we [the Court] lost our power to declare an Act of Congress void. I do think the Union would be imperiled if we could not make that declaration as to the laws of the several States."

- Justice Oliver Wendell Holmes
