Washington, D.C. — In a ruling that could reshape U.S. trade policy, the U.S. Court of Appeals for the Federal Circuit has declared a central part of President Donald Trump’s tariff program illegal, finding that the White House exceeded its legal authority under emergency powers. The decision, issued on Friday, August 29, 2025, delivers a sharp rebuke to Trump’s expansive use of unilateral trade measures but leaves the ultimate verdict to the Supreme Court.
The Court’s Decision: A Blow to Presidential Trade Powers
In a 7-4 ruling, the appeals court concluded that Trump violated the International Emergency Economic Powers Act (IEEPA) by using it to justify sweeping tariffs. Traditionally, IEEPA has been deployed for targeted sanctions, asset freezes, and restrictions against foreign adversaries. The court ruled that applying it to tariffs — which are legally classified as taxes — falls outside the president’s authority.
The authority to tax, which includes tariffs, rests squarely with Congress,
the ruling stated, underscoring that only lawmakers have constitutional power over trade revenue.
The decision specifically voids the “reciprocal tariffs” Trump imposed in February 2025 on imports from China, Mexico, Canada, and India, as well as the “trafficking tariffs” of April 2025, which targeted nations accused of failing to stop migration and drug flows into the U.S.
Tariffs Still in Effect — For Now
Despite the ruling, the tariffs remain in place. The court issued a temporary hold until October 14, 2025, allowing the Trump administration to appeal to the Supreme Court.
That appeal is virtually guaranteed. Trump blasted the decision on his social media platform, Truth Social, calling the court “highly partisan” and labeling the outcome a “total disaster for the Country.”
We will take this to the Supreme Court, and we will win. America must be able to protect its workers without begging Congress for permission,
Trump posted.
Potential Financial Fallout
If the Supreme Court upholds the appeals court ruling, the administration may be forced to refund billions of dollars in tariff revenue collected from U.S. importers over the past year. The Justice Department has warned that such refunds could push the government toward what it called “financial ruin,” given the sheer scale of tariffs levied under Trump’s trade program.
Trade groups and importers, who filed the lawsuit, argue that they have faced devastating costs since the tariffs went into effect. Many are already preparing legal claims for refunds should the Supreme Court rule against the White House.
Impact on U.S. Trade Policy
The ruling marks a significant setback for Trump’s broader trade agenda, which has relied heavily on executive authority to impose tariffs without congressional approval.
While the decision does not affect tariffs imposed under Section 232 of the Trade Expansion Act (steel and aluminum) or Section 301 of the Trade Act of 1974 (intellectual property violations against China), it directly undermines Trump’s use of emergency powers to levy sweeping trade measures.
Legal scholars say the ruling could redefine the balance of power between the executive and legislative branches in trade matters.
This case strikes at the heart of Trump’s strategy to unilaterally weaponize tariffs,
said Rachel Kim, a Georgetown law professor specializing in international trade.
If upheld, it will slow the speed and limit the scope of future tariff actions.
A History of Aggressive Tariff Policy
Since his first term, Trump has made tariffs the centerpiece of his economic and foreign policy toolkit, arguing they are necessary to protect U.S. workers and punish trade partners for “cheating.”
- 2018–2020: Trump imposed tariffs on steel, aluminum, and hundreds of billions in Chinese goods, sparking a U.S.-China trade war.
- 2025: Returning to office, he escalated further, imposing “reciprocal tariffs” on imports from U.S. trading partners to close trade deficits, and “trafficking tariffs” to pressure nations on immigration and drug enforcement.
- Criticism: Economists have long warned that such policies raise costs for U.S. consumers and disrupt supply chains.
The appeals court decision marks the first major judicial check on Trump’s second-term trade strategy.
Political Ramifications
The ruling arrives at a volatile political moment. With the 2026 midterm elections looming, Trump has sought to rally his base around his tough-on-trade agenda. His critics argue that the court’s decision underscores the dangers of concentrating economic power in the executive branch.
Democrats hailed the ruling as a victory for constitutional checks and balances. Senator Elizabeth Warren called it “a long-overdue rebuke of Trump’s abuse of emergency powers.”
Republicans, however, largely defended Trump. Senator Josh Hawley warned that the decision “ties America’s hands” against China and undermines the president’s ability to respond to foreign economic threats.
Business and Global Reaction
Global markets responded cautiously to the ruling, with stocks of major importers rising on hopes of tariff relief. Asian markets, particularly in China and India, welcomed the decision, while Canadian and Mexican officials signaled they would monitor the appeal closely.
U.S. business groups were quick to celebrate. The National Retail Federation called the ruling a “victory for American consumers and businesses that have borne the brunt of Trump’s unlawful tariffs.”
Still, uncertainty remains until the Supreme Court renders its decision.
What’s Next?
The Trump administration now faces a tight deadline to appeal before the tariffs are voided on October 14, 2025. The Supreme Court is expected to take the case, given its constitutional significance.
The outcome could redefine not only Trump’s trade program but also the scope of presidential authority in economic policymaking for decades to come.
This case is not just about tariffs — it’s about who holds the power to shape America’s trade policy,
said Kim.
If the Court sides with Trump, it could cement an era of unilateral presidential trade authority. If not, Congress will reassert control.
Until then, the tariffs remain in force, businesses remain in limbo, and the political battle over trade continues to rage.
