The U.S. Supreme Court will hold oral arguments on November 5 regarding whether Trump can impose tariffs under the IEEPA.

BlockBeats News, on November 4, the U.S. Supreme Court will hold oral arguments on November 5 regarding a case that examines the boundaries of presidential "emergency powers." The core issue of the case is whether the president can impose broad tariffs on imported goods from around the world under the International Emergency Economic Powers Act (IEEPA).

The impact of this case goes far beyond trade policy itself. The Supreme Court's ruling will determine whether the president can bypass Congress by invoking emergency powers, potentially making this practice a tool for routine governance, and will have profound implications for the constitutional separation of powers and the limits of presidential authority.

The case originated from former President Trump, who declared three national emergencies in succession to impose tariffs on Canada, Mexico, and China; he then declared a fourth national emergency to impose a 10% global tariff on all imported goods and up to a 50% "reciprocal tariff" on specific countries and companies.

Multiple businesses and state governments subsequently filed lawsuits in federal court. The Brennan Center submitted "amicus curiae" briefs in several cases, arguing that long-term trade imbalances do not constitute an emergency or an "unusual and extraordinary threat," and that the IEEPA does not authorize the president to impose tariffs. The Supreme Court will decide whether the law grants the president a "tariff pen" that can bypass Congress.

Trump previously stated on November 3, "I will not go to court on Wednesday (the 5th) because I do not want to distract people from this important decision."
