The U.S. Supreme Court will rule on Friday on tariffs imposed by the Trump administration under the International Emergency Economic Powers Act, putting the fate of tariffs on China, Canada, the European Union and other major economies in their own hands. Lower courts have ruled that the president cannot use IEEPA to set country-specific tariffs. But experts say if the Supreme Court sides with the Trump administration, it could give the president the same authority and scope to impose taxes as he did with related tariffs.
“The law at issue here – IEEPA – doesn’t just apply to imports; it empowers the president to regulate imports, exports, sales, uses, possessions, etc.,” said Timothy Meyer, a professor of international business law at Duke University. wealth. “If the administration prevails based solely on its interpretation of this law, the president will have the ability to impose taxes, impose a sales tax, he can impose a property tax.”
Meyer explained that since the doctrine in this case hinges on the president’s power to regulate imports, and the administration believes regulation includes the power to impose tariffs to influence behavior, the same logic would allow the president to use taxes to achieve regulatory goals.
“If the president has the ability to impose taxes under a law that doesn’t mention taxes, then we’re really in a world where the president is not going to feel like he has the authority to do anything based on broadly worded statutes,” Meyer said.
The case is the latest test of the president’s executive powers and the Supreme Court’s first major ruling of the new year. While it’s unclear how the justices will rule, a victory for the Trump administration could have long-lasting and widespread consequences for the executive branch’s powers.
However, some legal experts and investors expect the president’s IEEPA tariffs to be partially or fully refuted because The judges were skeptical Controversy over the presidential authority to impose such taxes without congressional approval.
How the Supreme Court ruled
This decision would throw a wrench into Trump’s tariff plans and could be positive for the market, as it would mean the average effective tariff rate would fall further, below the currently estimated 12%.
However, some experts believe that the removal of tariffs will not have a significant impact on the market.
“There will be no significant changes to the basic tariff regime as a result of this decision,” said Ben Steyer, director of international economics at the Council on Foreign Relations. wealth.
Even if the IEEPA taxes are overturned, the government has other powers to impose taxes, including on goods the president deems to pose a threat to national security, and through short-term levies. trump aide months A hint that the administration will seek other administrative means to implement the president’s tariff plan. That means no matter what the Supreme Court rules, not much will likely change.
But implementing tariffs to replace IEEPA levies would be tedious. The government needs to impose individual tariffs on each country and each specific product, rather than imposing blanket tariffs like IEEPA.
“The main difference is that other laws have some kind of limitation,” Meyer said. “They generally require at least some minimal investigation and findings by executive agencies before the president takes action.”
How reimbursement works
It’s unclear when refunds could reach individuals if the Supreme Court blocks the tariff plan. If the government slows down the pace of implementation of IEEPA tariff reimbursements as a way to evade payments, the IEEPA tariff reimbursement schedule may be delayed.
“The Supreme Court will not decide how the government repays the money,” Steyer said. “Conceivably, the government might make it as difficult as possible to demand repayment.”
Business leaders have Dismissed the idea of refunding “Very complex” because it requires a long and arduous process to calculate how much recipients are owed.
Another point to note in the judge’s decision is who is eligible for reimbursement. During oral arguments, Judge Amy Coney Barrett expressed doubts about the government’s obligation to compensate all parties affected by the tariffs and raised the possibility of compensating only the plaintiffs in the case. While it’s unusual, Steyer said such a decision could prevent big market moves.
“This is historically unusual, but it will alleviate concerns that Wall Street may have about the fiscal impact,” Steyer said.
