Even if the U.S. Supreme Court were to rule that President Trump exceeded his authority in imposing sweeping tariffs under the 1977 International Emergency Economic Powers Act (IEEPA), that outcome would not necessarily spell the end of the matter. Legal experts and administration officials alike argue that alternate legal avenues may still enable the administration to impose or reinstate similar tariffs. This contentious case remains deeply rooted in the history of executive trade powers and corporate strategy — and even a court loss could trigger a renewed push for tariffs via other statutory frameworks.

IEEPA Under Fire and the Court’s Take

The legal saga begins with the IEEPA, a law enacted during the Cold War era to grant the president emergency powers to regulate international economic transactions. In the spring of 2025, the Trump administration invoked IEEPA to justify broad, economy-wide tariffs targeting trade deficits and fentanyl trafficking. These “Liberation Day” tariffs sparked immediate legal challenges. In May, the U.S. Court of International Trade ruled they exceeded presidential authority; the U.S. Court of Appeals for the Federal Circuit followed, declaring most of the tariffs illegal in a 7–4 decision. The court stayed its ruling until mid-October to allow time for appeal, effectively pushing the issue to the Supreme Court.

While the appeals court decision was a setback, those opposing it observe that only IEEPA-based tariffs were struck down. Tariffs under other statutes—such as national security or unfair trade law—remain intact. That distinction keeps the door open for alternate legal strategies to preserve or reinstate trade protections even if the Supreme Court ultimately denies the IEEPA-based approach.

Alternative Legal Paths and Congressional Levers

Should the high court uphold the appeals court ruling, administration officials are prepared to pursue fallback routes. Key among them is Section 338 of the 1930 Tariff Act, which allows the president to impose tariffs up to 50 percent against nations found to be discriminating against U.S. commerce. While this route requires formal investigations, it offers a more defensible legal grounding.

Other frameworks include Section 232 of the Trade Expansion Act, designed for national security-related tariffs, and Section 301 of the Trade Act of 1974, which addresses unfair trade practices. In addition, Section 122 of the Trade Act allows up to 15 percent tariffs for 150 days following a “balance of payments emergency.” But all these alternatives come with drawbacks: they tend to be narrower in scope, require procedural investigations, and lack the sweeping immediacy of IEEPA.

Indeed, experts warn that without congressional support, the administration’s capacity to sustain broad tariffs could be curtailed. A meaningful fallback would likely require legislation granting explicit authority for sweeping import duties—something that remains politically fraught.

What Lies Ahead in the Supreme Court and Beyond

As the case heads to the Supreme Court, the administration maintains its resolve. Treasury Secretary Scott Bessent has emphasized the ongoing need for emergency tools in the face of trade imbalances and national crises like the fentanyl epidemic. Even if the court rejects the IEEPA basis, he reiterated that alternative tools remain viable.

The court’s decision will have wide-ranging implications—not just for Trump-era policy, but for the division of trade authority between Congress and the president. If the court upholds the lower rulings, importers could seek refunds for tariffs already paid under IEEPA, potentially costing the government billions. And while IEEPA tariffs may fall, legally grounded but more incremental measures could take their place—sending a signal that the fight over executive trade power is far from settled.

Inside and outside courts, strategic calculation now centers on whether the administration can translate legal flexibility into political progress. Failing a favorable Supreme Court ruling, the future of tariff policy may hinge on Congressional action—or inventive legal workarounds under existing statutes married with investigation and narrow targeting. Even as the judicial battle unfolds, the story behind these tariffs—and the broader debate over executive authority—continues to evolve.
