Washington — On Sept. 4, 2025, President Donald Trump urged the Supreme Court to uphold broad import tariffs he imposed, warning that invalidating them would push the United States toward an economic catastrophe and asking the justices to act quickly.
Key Takeaways
- The administration asked the Supreme Court to reverse a Federal Circuit ruling that found most tariffs exceed presidential emergency powers.
- Solicitor General D. John Sauer requested an expedited review and urged the court to decide within a week whether to hear the case and to schedule arguments in early November.
- By late August, tariff revenue reached about $159 billion; the administration says tariffs could lower deficits by $4 trillion over 10 years.
- The U.S. Court of Appeals for the Federal Circuit ruled 7-4 that the 1977 International Emergency Economic Powers Act (IEEPA) does not authorize sweeping tariff actions.
- The tariffs remain in effect during litigation; some levies (on steel, aluminum and autos) were not covered by the appeals court decision.
Verified Facts
The Justice Department filed an emergency appeal asking the Supreme Court to overturn a July ruling by the U.S. Court of Appeals for the Federal Circuit. The appeals court’s 7-4 judgment concluded the IEEPA does not permit the president to impose general import taxes that Congress traditionally controls.
Solicitor General D. John Sauer told the high court the stakes are unusually high and requested a rapid procedural schedule: a week for the justices to decide whether to take the case and arguments in the first week of November. The administration included letters from the secretaries of Treasury, Commerce and State supporting urgent review.
The administration reports tariff receipts totaled roughly $159 billion by late August. The White House has cited analyses — including ones it says are from the Congressional Budget Office — projecting the tariffs would reduce deficits by about $4 trillion over the next decade, a claim disputed by critics and described as contingent on many assumptions.
The CBO’s own June analysis found the import taxes are likely to slow economic growth and add price pressure, estimating inflation could be about 0.4 percentage points higher annually in 2025 and 2026 than it otherwise would be. Federal Reserve Chair Jerome Powell has warned tariffs are contributing to higher prices for some goods while their long-term effects remain uncertain.
Context & Impact
The legal fight centers on the balance of trade powers between the presidency and Congress. The Constitution grants Congress authority over tariffs; over decades, some statutory authorities have allowed presidents to act quickly in crises. The Federal Circuit’s ruling rejects a broad reading of IEEPA that would effectively let a president set sweeping tariff policy without Congress.
Markets and trading partners have reacted to the tariffs and their uneven rollout. Businesses that import intermediate goods face higher costs, and some small firms have sued, arguing the levies are unlawful and harmful to their operations. At least one set of plaintiffs has prevailed twice in lower federal courts.
On the diplomatic front, the administration says tariffs have been used to extract concessions from the European Union, Japan and others. Critics counter that the measures have strained alliances and injected volatility into global supply chains.
Official Statements
The government argued that removing tariff authority would jeopardize negotiations and national defenses and could leave the country exposed to retaliation and fiscal disruption.

Unconfirmed
- The administration’s $4 trillion deficit-reduction figure is a projection that depends on policy permanence and economic responses and has been characterized as disputable.
- Claims that tariffs will materially reduce fentanyl flows or directly shorten Russia’s war in Ukraine are asserted by the administration but remain unproven in court filings.
- Whether the government would be required to refund collected duties if the tariffs are struck down is legally plausible but would depend on final rulings and implementation details.
Bottom Line
The dispute pits executive action against statutory and constitutional limits. The Supreme Court’s response — whether to fast-track review and how it frames presidential emergency powers — will shape U.S. trade policy, alter relations with allies and affect businesses that depend on imported inputs. For now, the tariffs stay in place while the legal process continues.
