““This breadth of constitutional law in barring extralegal legislation is revealing about more than the past. The reader will have to wait patiently until chapter 7 for details of the current regime of extralegal lawmaking, but the significance of the history can already be anticipated. In an era of administrative legislation, it often is assumed that when the U.S. Constitution grants legislative power to Congress, it does not bar the executive from issuing binding rules, making interpretations, or setting taxes—as long as the executive has legislative authorization or at least acquiescence. The history of constitutional law, however, reveals that constitutions developed to bar all extralegal lawmaking—the point being to confine government to ruling through the law. Thus, administrative legislation—whether by proclamation, rulemaking, interpretation, or taxation—is not a novel form of lawmaking, and it cannot, on account of its alleged novelty, escape constitutional restrictions. On the contrary, it is a return to the extralegal legislation that constitutions were established to prohibit.””
