Supreme Court Considers Limitations on Trump’s Tariffs

WASHINGTON — The Supreme Court appeared to restrict President Donald Trump’s ability to impose tariffs during a session on Wednesday.

During oral arguments, skepticism was evident from the justices on both sides. Attorney General John Sauer faced particularly pointed questions as he argued the legality of Trump’s use of emergency powers for the tariffs. “It’s Congress that has the authority to impose taxes,” Justice Sonia Sotomayor told Sauer. “You’re attempting to say that tariffs aren’t taxes, yet they do generate revenue from the American public.”

Trump’s tariffs were justified on two grounds, with the initial “Liberation Day” tariffs introduced in February on imports from Canada, Mexico, and China. Following a growing trade deficit, a second round of such tariffs followed in April, applying a 10% rate on imported goods, which could increase depending on the country.

Sauer argued that interpreting the language granting the president the power to “regulate imports” under the International Emergency Economic Powers Act (IEEPA) should also encompass tariffs, even if that specific term isn’t mentioned.

Chief Justice John Roberts pointed out that while Congress has incorporated tariffs in other contexts, it has not done so here. He noted that the justification seemed to provide broad authority to levy tariffs “on any product, in any country, in any amount, for any duration,” suggesting it was a significant power.

Sauer insisted that this law’s intent is to grant broader powers to tackle urgent issues. The justices emphasized two key legal doctrines: the principal interrogation doctrine, which mandates explicit Congressional approval for significant executive actions, and the non-delegation doctrine, which limits Congress from transferring excessive power to the executive branch.

Justice Neil Gorsuch expressed concern that the administration’s stance could enable future presidents to impose tariffs in response to threats like climate change, a notion Sauer acknowledged, while asserting that the Trump administration views such threats as a “hoax.”

Gorsuch remarked, “Once Congress delegates this power, it’s hard to retract. This seems to effectively grow executive authority at the expense of elected representatives.”

Judge Barrett raised a question regarding the process for refunding tariff revenue if Trump were to lose the case, asking if it would be “a complete mess.”

Representatives for small businesses and states contesting the tariffs also encountered challenging inquiries. While tariffs are classified as taxes, Roberts highlighted they still function as “foreign taxes” closely tied to the president’s diplomatic powers.

Roberts commented on the effectiveness of foreign tariffs in certain contexts. Several justices, especially Justice Brett Kavanaugh, sought to explore any precedents supporting the administration’s arguments. The administration pointed to President Richard Nixon’s imposition of a 10% tariff in 1971 under earlier legislation, which was upheld by appellate courts.

Kavanaugh questioned the reasoning behind allowing the president to suspend all trade while not permitting any tariffs, suggesting an imbalance of power. Amy Coney Barrett raised the possibility of chaos in the reimbursement process for companies if the tariffs were deemed unlawful.
