““Wilson insisted that the centralized administrative state must, by logic and necessity, replace or thoroughly alter the constitutional structure—particularly the Framers’ incorporation of Charles de Montesquieu’s separation-of-powers doctrine, essential to curtailing the likelihood of concentrated tyranny, which must be abandoned in principle. Otherwise there can be no real historical progress. “The study of administration, philosophically viewed, is closely connected with the study of the proper distribution of constitutional authority. . . . If administrative study can discover the best principles upon which to base such distribution, it will have done constitutional study an invaluable service. Montesquieu did not, I am convinced, say the last word on this head.”44 Hence the administrative state is to effectively replace the constitutional state, the latter being old and immovable.””
