What the New Deal Settled

This brief essay, written in conjunction with a symposium comparing the Franklin Delano Roosevelt and Obama presidencies, explores the absence of substantive due process arguments in the Affordable Care Act litigation and attendant public discourse. I argue that a substantive due process argument against the Act's individual mandate is at least as sound doctrinally as a federalism-based argument, but to the extent such arguments have been made, they have been rejected as frivolous. I suggest that this phenomenon may result in part from political obstacles to coalescing around and funding a substantive due process argument and in part from the shadow Lochner v. New York casts over arguments that may be characterized (even inaccurately) as sounding in economic due process. The ACA litigation demonstrates one way in which Lochner's anticanonicity distorts modern legal argument.
