The Supreme Court’s decision on President Trump’s use of the 1977 International Emergency Economic Powers Act (IEEPA) to enforce global tariffs is eagerly anticipated. This ruling could remove an important tool used by the President to retaliate against countries that have provoked his displeasure on non-trade-related political issues. The case, initiated by small business organizations and various states, is being reviewed by the court, including three justices appointed by Trump. The outcome’s timing remains uncertain.
President Trump is the first to utilize the IEEPA to impose tariffs, a law typically applied for imposing economic sanctions on adversaries. The statute grants the president authority to address threats to national security, foreign policy, or the economy. Trump declared a national emergency due to a $1.2 trillion U.S. goods trade deficit in 2024, despite the country consistently running trade deficits since 1975.
U.S. Treasury Secretary Scott Bessent believes the Supreme Court will uphold the IEEPA-based tariffs. If the court invalidates these tariffs, the administration can resort to other tariff provisions, including Section 122 of the Trade Act of 1974 and Section 338 of the Tariff Act of 1930.
Critics argue that only Congress, not the President, has the constitutional authority to impose taxes and tariffs, questioning the delegation of such powers. The major questions doctrine, which demands clear congressional authorization for significant executive actions, has been cited in challenging Trump’s tariff decisions.
Trump’s tariffs have drawn mixed reactions, with some praising them for prompting trade concessions, while others express concerns about long-term reliance on tariff revenues. The potential impact of the Supreme Court’s ruling on the IEEPA tariffs remains a point of contention among economists and policymakers.
