The battle over tariffs has shifted to the federal courts. The Supreme Court may have the last word on whether the Trump administration went too far when it imposed tariffs on both allies and adversaries on “Liberation Day.” Let’s hope the highest court in the land stands on principle and affirms the decision of the Court of International Trade.

The “Liberation Day” tariffs are bad policy because of the unconstitutional manner by which they were imposed and the mere fact that tariffs are taxes. The way they were imposed violates the separation of powers.
