WASHINGTON — The U.S. Supreme Court is set to hear a significant case in President Donald Trump’s second term, concerning emergency tariffs that small business owners claim jeopardize their operations. The central issue is whether Trump can impose comprehensive tariffs under the International Emergency Economic Powers Act (IEEPA), marking the first use of this statute to levy taxes on imports. This lawsuit, challenging the scope of Trump’s presidential authority, represents the administration’s first fully argued appeal before the high court. Previously, Trump’s appeals were expedited via the shadow docket, bypassing full arguments.

President Trump initially planned to attend the arguments but will now join a business forum in Miami. The Supreme Court session begins at 10 a.m. Eastern, with live audio available on the court’s website. Treasury Secretary Scott Bessent intends to be present, aiming for a “ringside seat,” he told Fox News.

Michael McConnell, a Stanford Law School professor, calls the tariff case “one for the ages.” He asserts that while the president holds constitutional powers, imposing tariffs without Congress is beyond Trump’s authority as tariffs equate to taxes on American importers. McConnell argues IEEPA is designed for sanctions against adversarial nations, not taxing lawful trade.

Tariffs a ‘terrible and unsustainable weight’

Victor Schwartz, head of VOS Selections, a wine and spirits importer, describes Trump’s tariff policy as an “existential threat.” Schwartz leads a lawsuit by small businesses and Democratic state attorneys general opposing duties up to 50% based on product origin. Schwartz emphasizes that Americans bear the tariff costs, which have become an unsustainable burden. His company, unable to import wines from South Africa due to 30% tariffs, is among others challenging the levies.

States like Arizona, Colorado, and Oregon, backed by Democratic attorneys general, also filed lawsuits. Both the U.S. Court of International Trade and the Federal Circuit Court ruled Trump’s IEEPA tariffs unconstitutional. The justices will also consider a separate case from Illinois-based toy companies disputing Trump’s tariffs, impacting imports from countries like China and India, taxed up to 50%.

Trump says ‘country is wealthy again’

Trump stated the case is “one of the most important decisions” in U.S. history, suggesting the economy risks deterioration without his tariffs. He claims tariffs have revitalized U.S. wealth and serve as a negotiation tool, though many trade deals remain incomplete. U.S. customs duties collected $195 billion by September, per a Treasury monthly statement. Treasury Secretary Bessent warned the Supreme Court that halting tariffs could lead to “catastrophic” financial impacts.

Despite administration claims, Scott Lincicome from the Cato Institute argues against the notion that tariffs are financially crucial, emphasizing U.S. debt issues persist regardless of tariffs. Cato’s brief argues against the administration’s interpretation of IEEPA, highlighting potential overreach of presidential power.

Some Republicans break ranks

The case has drawn extensive friend-of-the-court briefs, including one signed by hundreds of Democrats and Sen. Lisa Murkowski, a Republican from Alaska. Lawmakers contend IEEPA lacks constraints typical of tariff legislation. In a symbolic move, some Republicans joined Democrats in passing resolutions ending Trump’s tariff-triggering emergencies, although these measures are unlikely to advance in the GOP-led House.

Cato’s Supreme Court brief criticizes the administration’s expansive reading of IEEPA as undermining the separation of powers. Meanwhile, the America First Policy Institute defends tariffs as central to Trump’s “America-first” strategy, asserting presidential authority to impose such taxes.

Executive orders and more

Trump initiated tariffs under IEEPA via executive orders targeting countries like China, Canada, and Mexico, citing illegal fentanyl smuggling. He expanded the tariffs globally, declaring trade imbalances a national emergency. Recently, Trump imposed a 25% tariff on Indian goods, totaling 50%, due to India’s Russian oil imports. In August, he levied a 40% tax on Brazilian goods, reacting to Brazil’s prosecution of former President Jair Bolsonaro for alleged coup attempts.
