The Supreme Court is set to review President Donald Trump’s use of the 1977 International Emergency Economic Powers Act (IEEPA) to implement extensive global tariffs. This ruling could impact Trump’s ability to impose tariffs on countries that he disagrees with on non-trade issues. The court, with a conservative majority, including three justices appointed by Trump, will hear the case brought by small business groups and various states. Trump is the first president to use the IEEPA to enforce tariffs, which is typically used for imposing economic sanctions on adversaries. The law allows the president to address threats to national security, foreign policy, or the economy. Trump justified the tariffs by declaring a national emergency due to a $1.2 trillion trade deficit in 2024, despite the U.S. running trade deficits since 1975.
If the Supreme Court rules against the IEEPA-based tariffs, the administration can resort to other tariff authorities, such as the Trade Act of 1974 and the Tariff Act of 1930. Trump has already utilized various tariff provisions for sectors like autos, copper, and pharmaceuticals. Treasury Secretary Scott Bessent believes that the tariffs will be upheld, but alternative tariff authorities can be employed if needed. Critics argue that Congress, not the president, should have the authority to impose tariffs, citing the major questions doctrine which requires clear congressional authorization for significant executive branch actions.
Trump’s tariff strategy includes imposing tariffs on specific countries to address trade deficits and using tariffs as leverage in trade negotiations. The administration believes these tariffs have led to concessions from major trading partners. Investors are concerned that overturning the IEEPA tariffs could disrupt financial markets and revenue streams. The risk of becoming reliant on tariff revenue poses challenges for future administrations in reducing duties. The potential impact of the Supreme Court’s decision on the tariff policy remains a point of contention.
