I often wonder what constitutional law professors tell their students about the big cases. These are the canonical cases every law student discusses at one time or another during her law school years, cases such as Youngstown Steel and Brown v. Board of Education, Marbury v. Madison and Dred Scott, South Carolina v. Katzenbach and McCulloch v. Maryland. I suspect that most professors keep it simple. They talk about the Constitution and surely they talk about "law" as an abstract proposition. They also bring up prior cases and spend much time "distinguising" them or "reconciling" them, or else arguing why the present case follows seamlessly from prior, settled law.
I understand why they do this. They are law school professors, and this is a place where law must matter. if not law, then what?
But here is the problem. Constitutional law is not about "law" in the formal sense. That is, constitutional law is not about the formal meaning of the privileges and immunities clause or the necessary and proper clause. To be sure, this is what law professors would have you believe. I am here to tell you that they are either lying to you (and themselves) or else they are so imbued in the law school orthodoxy that they can't tell any better. And that's too bad.
