The Supreme Court is set to rule on President Donald Trump’s use of the 1977 International Emergency Economic Powers Act (IEEPA) to impose global tariffs. This ruling could impact Trump’s ability to levy tariffs on countries for non-trade political reasons. The court, with a conservative majority including three Trump-appointed justices, is hearing a challenge brought by small business groups and states. Trump is the first president to utilize the IEEPA for imposing tariffs, citing a national emergency due to a $1.2 trillion U.S. goods trade deficit in 2024.
If the Supreme Court strikes down the IEEPA-based tariffs, the administration could resort to other tariff authorities such as Section 122 of the Trade Act of 1974 and Section 338 of the Tariff Act of 1930. Trump has also employed Section 232 of the Trade Expansion Act of 1962 to impose tariffs on strategic sectors for national security reasons.
Challengers argue that the authority to issue tariffs lies with Congress, not the president, citing the major questions doctrine. This doctrine requires significant executive actions to be explicitly authorized by Congress. However, Trump’s administration officials believe that his tariffs have coerced major trading partners to negotiate concessions that would persist post any Supreme Court decision.
Despite facing opposition to his tariff policies, Trump has continued to implement tariffs on various goods, aiming to address trade deficits and trade-related issues with countries like China, Canada, and Mexico. The potential repeal of IEEPA tariffs could create uncertainty, especially in financial markets, due to the impact on revenue collections and deficit reduction efforts.
Experts warn about the risk of becoming overly reliant on tariff revenue, which could hinder future administrations from reducing tariffs. The outcome of the Supreme Court ruling on the IEEPA tariffs could have far-reaching implications on trade policies and revenue streams moving forward.
