Notre Dame students react to landmark case

The Supreme Court heard oral arguments last week in a closely-watched case challenging the federal government’s authority to impose broad tariffs under the International Emergency Economic Powers Act (IEEPA). The dispute centers on whether the president may invoke emergency economic powers to restructure trade policy without explicit congressional authorization, a question with major implications for the future of tariffs and executive authority.

The case arises from the fallout of Trump’s “Liberation Day” tariffs last April, after the President invoked emergency powers to levy global tariffs. Declaring that foreign countries’ trade practices posed an “unusual and extraordinary threat” to the U.S. economy, the president imposed a 10 percent global tariff and “reciprocal” duties of up to 50 percent on selected countries and companies. Although successive administrations have maintained many of those duties, the suit now before the Court alleges that IEEPA was never meant to authorize sweeping tariffs and that such actions usurp Congress’s constitutional power to regulate foreign commerce.

During oral arguments, several justices questioned the limits of executive authority under IEEPA and its wartime predecessor, the Trading with the Enemy Act (TWEA). Under the statute, the president’s power expressly includes the authority to “prohibit” imports in an emergency. Justice Barrett asked how a president could bar all imports but not impose even a one percent tariff. The defense answered that to “regulate … importation” must include tariffs because a tariff is the normal means of controlling imports. Justice Elena Kagan noted that “the natural understanding of ‘regulate,’ even though, in fact, we can regulate through taxes” isn’t in play in this code. She continued, “We don’t typically understand [regulate] to refer to duties or taxes or tariffs or anything of the kind.” 

Chief Justice John Roberts pushed the topic in a different direction. He questioned whether accepting the government’s argument would allow future presidents to subvert Congress and rewrite tariff schedules at will by declaring market imbalance a national emergency. Justice Jackson supported this line of reasoning by pointing out that Congress could not have simply delegated one of its core powers through the IEEPA. She stated that “every time for 238 years, it’s done so explicitly, always with real limits.”

The outcome of the case will impact the executive branch’s ability to impose tariffs. If the Court rules against the government, it may compel Congress to reclaim its tariff power and force future presidents to negotiate with lawmakers before imposing new duties. It would also force the government to refund billions of dollars collected since the tariffs were put into place in April, a process Justice Barreett admitted would be inherently “messy.” President Donald Trump issued a warning on November 10, saying, “If a President is not allowed to use tariffs, we will be at a major disadvantage against all other Countries throughout the World … we would be defenseless.”

A ruling in favor of the executive would affirm a model of economic governance in which the White House wields significant unilateral authority over trade policy.

On campus, the case has sparked vigorous debate among students across ideological lines. Some argue that these tariffs are a vital strategic tool, while others see them as economically destructive and constitutionally suspect.

Junior Marcos Braceras defended the use of tariffs as a safeguard against predatory foreign markets. “Free trade only works when both sides respect the rules,” he told the Rover. “Tariffs aren’t protectionist if they’re restoring fairness. They’re leverage.”

Braceras also argued that Congress has failed to act decisively on trade for decades, saying, “If the legislative branch won’t respond to real economic threats, the president has to. Otherwise we’re stuck while other countries eat our lunch.”

Others disagreed. Sophomore Aarav Ghimire criticized the tariffs as a hidden tax on consumers that fails to achieve long-term industrial revival. “Every tariff is sold as ‘temporary’ and ‘targeted,’” he said to the Rover, “but prices go up immediately and stay there, which comes at the expense of ordinary people.”

Ghimire also warned against the constitutional consequences of expanded executive authority, saying, “If emergency law can justify rewriting trade policy, what can’t it justify? Economic emergency is the most elastic category imaginable.”

Some students saw the Supreme Court case as not merely a legal technicality but as a referendum on accountability itself. Sophomore Anvita Japura said the broader issue is democratic responsibility, telling the Rover, “Whether you support tariffs or not, there’s something wrong when trade policy is made through emergency decrees instead of legislation.”

With the economy ranking as voters’ top concern heading into the November election, the Court’s decision could ripple far beyond the courtroom. A ruling is expected before the end of the term in June, just as the 2026 midterm campaign season accelerates and trade once again becomes a central theme in American politics.
