The law invoked by Trump—the International Emergency Economic Powers Act—dates back to 1977. It authorizes the president to take action in response to an unusual and extraordinary foreign threat. Never since its enactment had it been used to impose tariffs on nearly all of the United States’ trading partners at the same time. Neither Reagan, nor Bush, nor Clinton, nor Obama had dared to misuse it in this way. It wasn’t until 2025 that a president attempted to transform this Cold War-era law into a universal tariff tool.

A Massive Semantic Misuse

Trump transformed an emergency law into a permanent budgetary tool. The conservative justices did not tolerate it. Even Clarence Thomas, even Samuel Alito—the names that were theoretically supposed to protect the Trump administration—joined the ruling. This almost never happens. One must go back to the decisions limiting war powers under Truman to find a comparable precedent of institutional rebuke.

The question the justices posed is devastatingly simple: where is the emergency? Where is the unusual and extraordinary threat that justifies taxing Switzerland, Brazil, Vietnam, and Canada simultaneously? Where is the new, sudden, unforeseeable development that demands an immediate presidential response? Trump cited the chronic trade deficit. The judges responded: a deficit that has persisted for fifty years is not an emergency; it is a structural situation.

The “major questions” doctrine strikes again

The Court applied the “major questions” doctrine: when an executive decision has massive economic consequences, it requires explicit authorization from Congress. Trump had none. He governed by decree where he should have legislated. The result is a precedent that will constrain all his successors, Democrats and Republicans alike. This may be the ultimate irony: by pushing too far, Trump has just restored a constitutional balance that many believed was lost.
