Supreme Court to fast-track review of Trump tariffs

 September 10, 2025

The Supreme Court has decided to fast-track its review of the Trump administration’s wide-reaching tariffs, setting the stage for a pivotal ruling with massive financial stakes.

CNBC reported that the Court’s decision to expedite the case could determine whether the federal government must return up to $1 trillion in tariff revenue, while also clarifying the scope of presidential powers under trade law.

The tariffs in question, first announced on April 2, included measures tied to fentanyl imports and broad duties on foreign goods. The Trump administration imposed a baseline tariff of 10% on imports from many nations, with rates rising as high as 50% for countries such as Brazil and India.

Supreme Court Sets Expedited Schedule

The justices agreed to hear the government’s appeal on an accelerated timeline, with oral arguments scheduled for the first week of November. The session will last one hour, signaling the Court’s interest in resolving the matter quickly.

The appeal consolidates two separate challenges to the tariffs, which were brought by seven small businesses and a dozen states. Lower courts ruled in favor of these plaintiffs, striking down the measures as unconstitutional overreach by the president.

In late August, the U.S. Court of Appeals for the Federal Circuit issued a 7-4 decision finding that former President Donald Trump exceeded his authority under existing law. The court concluded that Congress, not the White House, has the sole power to impose tariffs.

Dispute Over Presidential Authority

Trump had invoked the International Emergency Economic Powers Act, or IEEPA, as the basis for the tariffs. The administration argued that the law granted the president broad authority to act in response to threats like fentanyl trafficking and economic risks posed by foreign trade partners.

However, both the appeals court and a federal judge rejected that view, determining that IEEPA did not allow unilateral action to impose duties. The rulings effectively limited the scope of presidential powers in the realm of trade policy.

Despite these findings, the tariffs have remained in effect during the ongoing appeals process. According to the Tax Foundation, the duties cover roughly 70% of all U.S. imports, placing widespread costs on consumers and businesses.

Potential for Massive Refunds

If the Supreme Court affirms the lower courts’ rulings, the Treasury Department could be compelled to return between $750 billion and $1 trillion in collected revenue. Such a decision would have far-reaching economic implications for both the government and private industry.

The contested tariffs include a 25% levy on goods from Canada, China, and Mexico, which the administration tied to efforts to address the flow of fentanyl. Critics argued that the connection was tenuous and unrelated to established trade law standards.

Business groups and state governments involved in the lawsuits say they have suffered direct harm from the measures, citing increased costs and disrupted supply chains. Their legal challenges emphasized that the Constitution grants tariff power to Congress, not the executive branch.

Legal Arguments and Public Statements

Jeffrey Schwab, senior counsel and director of litigation at the Liberty Justice Center, expressed optimism about the Supreme Court’s upcoming review. He said his organization expects the Court to align with the lower rulings.

“We are confident that the Supreme Court, like the CIT and the Federal Circuit, will recognize that the President does not have unilateral tariff power under IEEPA,” Schwab stated.

He added that “Congress, not the President alone, has the constitutional power to impose tariffs,” underscoring the separation of powers issue at the heart of the dispute.

Implications for Trade and Governance

The expedited hearing reflects the Court’s recognition of the case’s importance to both trade policy and constitutional authority. By moving quickly, the justices aim to resolve uncertainty surrounding one of the largest tariff disputes in recent history.

The outcome will determine not only the fate of hundreds of billions of dollars but also the boundaries of executive power in shaping economic policy. Until then, the tariffs will remain in place, continuing to affect the majority of imported goods entering the United States.
