Summary

Who actually decides when the United States goes to war—Congress or the president? Richard Epstein traces the Constitution’s original division of war powers from 1789 to the present and explain how practice, politics, and modern warfare have steadily shifted authority toward the presidency. Along the way, they explore declarations of war that never happen, authorizations that never expire, emergency actions that become routine, and why Congress so often prefers not to decide at all. Professor Epstein argues that America now operates under two constitutions—the one we wrote and the one we live with.

Welcome to The Libertarian. I am Charles C.W. Cook, the host, and I'm here with the Libertarian himself, Richard Epstein. Richard, welcome to your own show.

0:20.5

It's always a pleasure to be a guest on my own show.

0:23.0

Of course. All right. Well, this is a production of the Civitas Institute at the University of Texas at Austin.

And today we're going to talk about war powers. We talked a couple of episodes ago, specifically about the administration's

0:44.0

attacks on narco boats. This will be much broader. So let's go all the way back to the founding,

0:52.1

to the Constitution. The Constitution splits powers in some sense between Congress

0:59.5

and the presidency. Congress has the power to declare war. The presidency has, well, I'll ask you,

1:07.4

Richard, what powers it has. What were the founders trying to achieve when they put the war powers into both Article 1, Congress, and Article 2, the presidency?

1:17.0

Well, I mean, the basic division has always been that the executive has to act with dispatches on duty 24-7, so he has to take the initiatives in particular cases.

1:29.5

But before he can act, Congress,

1:34.7

which is a broader and more representative body, was supposed to engage in activities of deliberation, whereby I would decide whether or not to go to war with a foreign nation.

1:40.0

And so the theory was that Congress would then organize it. And then the president be the commander in chief of the Army and the Navy and of the militiamen

1:48.1

called into the active service of the United States.

1:51.3

And there is a peculiar kind of separation of powers there because the president cannot

1:56.5

call them up unilaterally.

1:58.3

There has to be a congressional authorization. But very early on,

2:02.2

Congress actually did authorize it in a blanket way. So that particular check and balance was

2:07.1

eliminated by Congress. The question then is, what is the powers of a commander in chief?

2:13.7

And it turns out the most instructive case on that particular issue is a case called the steel seizure cases involving the commissioner or the Secretary of Commerce, a man named Sawyer, and he was sued on the grounds that he could not commandeer the various steel mills during the Korean War because the

2:36.2

President's Commander-in-Chief power did not extend to dealing with civilian facilities of one

unitary executive version that Trump had, it says that under the major opinion
