This week on The Libertarian podcast, Professor Epstein leads us through the intricacies of the Supreme Court’s ruling in Zivotofsky v. Kerry, a case nominally about which branch of the federal government gets to determine what’s printed inside your passport — but one that may have profound implications for the separation of powers when it comes to foreign affairs. It’s a typically comprehensive Epsteinian survey that touches on everything from the weaknesses of Justice Kennedy’s interpretive style to the propriety of signing statements.
