Trump Tariff Supreme Court Ruling 2026: Greer Vows Immediate Replacement if Struck Down

2 min readSource

USTR Jamieson Greer confirms the Trump admin will replace global tariffs immediately if the Supreme Court rules them illegal. Focus on the impact on Korea and IEEPA.

They'll start the next day. The Trump administration isn't waiting for the Supreme Court's permission to keep its global tariff regime alive. U.S. Trade Representative Jamieson Greer told The New York Times that if the high court strikes down current trade levies, the administration will begin reconstituting them immediately to address the president's economic objectives.

The legal battle centers on the 1977 International Emergency Economic Powers Act (IEEPA), which Trump utilized to impose country-specific reciprocal tariffs on partners like South Korea. The Supreme Court could rule as early as this week. A loss for the administration would be a significant blow, potentially forcing the U.S. to pay back "many hundreds of billions" or even "trillions of dollars" in refunds to companies and countries.

We would start the next day to reconstitute tariffs to respond to the problems the president has identified.

Implications for Global Trade and the Korean Deal

Currently, South Korea faces a 15% reciprocal tariff, a reduction from the initial 25% following a bilateral agreement where Seoul committed $350 billion in U.S. investments. If the Supreme Court rules against the IEEPA-based tariffs, these agreements could enter a period of legal limbo. Greer indicated that advisers have provided Trump with a variety of legal options to ensure trade objectives remain met, suggesting a pivot to other statutes if necessary.
