“On Wednesday, the U.S. Supreme Court will hear oral arguments on whether some, though not all, of President Donald Trump’s tariffs are legal, including some of the ones on Canada; China; Mexico; and, actually, the entire rest of the world. At issue is the president’s ability to set rates for import duties (taxes, for the layman) under an entirely novel reading of Carter administration-era legislation meant to address sudden national emergencies: the International Emergency Economic Powers Act (IEEPA). But at heart is something bigger, which is the question of whether the U.S. Constitution, which grants exclusive power over both taxation and foreign commerce to Congress, still matters, or whether the executive branch can set tax rates without recourse to the will of the people or oversight whatsoever.” (11/03/25)
