In a 6–3 decision, the Supreme Court of the United States ruled that several of President Trump’s tariffs were imposed without proper legal authority. The majority found that the administration exceeded the powers granted under federal trade law when it used emergency economic statutes to justify broad tariffs on imported goods.

As a result of the ruling, the tariffs in question are invalidated. That opens the door for affected businesses to seek refunds on duties they paid — a total that could exceed $150 billion, depending on how claims are processed and whether Congress or the administration takes further action.

The decision has major implications for presidential trade powers going forward. It reinforces limits on how emergency authorities can be used in economic policy and could reshape how future administrations approach tariffs and international trade disputes.
