The Supreme Court’s decision in Zivotofsky v. Kerry held that Congress violated the separation of powers by enacting a statute that purported to compel the President to issue statements that contradict his policy of strict neutrality on the status of Jerusalem. In a recent post, I analyzed a disagreement between the majority and the dissent on the significance of foreign perceptions of U.S. law. I’ve now written a second post on the case, this time exploring Zivotofsky‘s implications for the constitutionality of diplomatic communications between Congress and foreign governments. It’s available over at Lawfare.
