It started with a blog post. When the Trump administration invoked emergency powers to impose sweeping tariffs, law professor Ilya Somin suggested in passing that someone ought to challenge it in court — and then found himself co-counsel in the case that reached the Supreme Court.

In this episode, Aaron Ross Powell talks with Somin, professor of law at George Mason University's Antonin Scalia Law School and the Kenneth Simon Chair in Constitutional Studies at the Cato Institute, about how V.O.S. Selections v. Trump came together, why the Court held that the IEEPA doesn't authorize tariffs at all, and what the major questions and nondelegation doctrines mean for presidential power. They also explore what should count as a genuine "emergency," why the courts alone can't restrain executive overreach, and how litigation and ordinary politics have to work together to keep power in check.
