Adam B. Cox, NYU Law, has published The Invention of Immigration Exceptionalism in the Yale Law Journal:
American immigration law is a domain where ordinary constitutional rules have never applied. At least, that is the conventional wisdom. Immigration law’s exceptionalism is widely believed to flow directly from the Supreme Court’s invention, in the late nineteenth century, of the so-called plenary power doctrine. On the standard account, that doctrine has long insulated immigration policies from constitutional scrutiny. The plenary power doctrine is thought to permit everything from President Trump’s Muslim ban to the indefinite detention of migrants at the border.
But the reigning historical account of immigration exceptionalism is wrong. Revisiting the field’s canonical cases, this Article reveals that the plenary power doctrine lawyers and judges argue over today was not created in a series of late nineteenth-century cases. Far from being exceptional, those cases applied the then-standard framework linking due process and the separation of powers. By failing to understand that nineteenth-century immigration law was ordinary public law, scholars and jurists have, for decades, badly misunderstood immigration law’s foundational cases. We have also overlooked the role that immigration law played in the development of modern public law. At the turn of the twentieth century, immigration law evolved apace with the rest of public law as both underwent a dramatic transformation. In some cases, immigration law even led the revolution, driving the development of the legal regime we now call “administrative law.”
Immigration exceptionalism is thus a recent invention. Indeed, it might be more accurate to say that the immigration plenary power doctrine was invented in the Roberts Court rather than in the late nineteenth century. Once we locate immigration exceptionalism in its proper moment, we can better appreciate immigration law’s centrality to the development of American public law. We can also assemble new arguments against the modern exceptionalism that is responsible for the very worst parts of immigration law today.
