WASHINGTON — Consumer Watchdog filed an amicus curiae brief in the US Supreme Court urging the Justices to strike down President Donald Trump’s sweeping “emergency” tariffs, warning that unchecked presidential power under the International Emergency Economic Powers Act (IEEPA) threatens both consumers’ pocketbooks and the Constitution’s separation of powers. The brief argues that:

• Tariffs act as a regressive tax that raises prices on consumer household essentials and disproportionately burdens families and small businesses.
• IEEPA lacks an “intelligible principle”—it provides no limits on the President’s ability to impose, vary, or lift tariffs, no standards for rate or duration, and no provision for judicial review.
• Recent precedent underscores that Congress must set clear boundaries when delegating economic power; IEEPA, by contrast, contains none.
