In ruling against the sweeping tariffs that President Donald Trump purported to impose under the International Emergency Economic Powers Act (IEEPA), the U.S. Court of Appeals for the Federal Circuit did not settle the question of whether that law authorizes import taxes. Nor did it uphold the injunction that the Court of International Trade (CIT) issued against the tariffs on May 28. But the Federal Circuit agreed with the CIT that the tariffs are unlawful, and its reasoning highlights the audacity of Trump's claim that IEEPA empowers him to completely rewrite tariff schedules approved by Congress.
The decision addresses two challenges to Trump's tariffs, one brought by several businesses and one filed by a dozen states. Both sets of plaintiffs argued that Trump had illegally seized powers that belong to Congress.
The Constitution gives Congress, not the president, the power to "lay and collect taxes, duties, imposts and excises." And although Congress has delegated that authority to the president in "numerous statutes," the Federal Circuit notes in an unsigned opinion joined by seven members of an 11-judge panel, it has always "used clear and precise terms" to do so, "reciting the term 'duties' or one of its synonyms." Furthermore, Congress always has imposed "well-defined procedural and substantive limitations" on the president's tariff powers.
