Supreme Court Strikes Down Trump Tariffs, New Duties Imposed

The Supreme Court on Friday struck down some of former President Donald Trump’s most sweeping tariffs, a decision that upends a core set of tariffs imposed using the 1977 International Emergency Economic Powers Act (IEEPA). In response, President Trump announced a new 10% global tariff, citing alternative statutory authorities.

Supreme Court Ruling on IEEPA Tariffs

The nation’s highest court ruled 6-3 that Trump exceeded his authority when imposing sweeping tariffs under IEEPA, a law intended to address national emergencies. Chief Justice John Roberts, writing for the majority, stated that granting the President such broad power to unilaterally impose tariffs would be a “transformative expansion” of executive authority. The court noted that no president had previously invoked IEEPA to impose tariffs of this magnitude.

Trump’s Response: A New 10% Global Tariff

Following the ruling, President Trump harshly criticized the decision, calling it a “disgrace” and vowing to implement new tariffs. He announced a new 10% global tariff, citing Section 122 of the Trade Act of 1974 as the legal basis. Trump also mentioned Section 301, which allows for tariffs based on unfair trade practices, as a potential avenue for future duties. He claimed that foreign countries were “ecstatic” over the court’s decision but would soon find their celebrations short-lived.

Impact on the Economy and Markets

The Supreme Court’s decision is expected to provide relief to businesses and potentially lead to refunds of tariffs already paid. Wall Street reacted positively to the news, with the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite all experiencing gains. Karl Schamotta, chief market strategist at Corpay, suggested the ruling would reduce uncertainty for corporations and investors and lead to a “modest compression” in currency volatility.

Businesses React to the Ruling

Business owners have expressed varied reactions. Beth Benike, co-founder of Busy Baby, stated that the uncertainty surrounding the IEEPA tariffs had forced her to halt imports from China. The ruling allows her to resume shipments without incurring the additional costs. However, Drew Greenblatt, owner of Marlin Steel, had supported the tariffs, believing they created a more level playing field for domestic manufacturers.

Refund Process and Potential Challenges

The ruling raises questions about the process for refunding the more than $133.5 billion in tariffs collected under IEEPA. The court did not provide instructions on how to handle the refunds, leaving the administration to determine the logistics. Treasury Secretary Scott Bessent indicated that resolving the refund process could grab weeks, months, or even years. Justice Kavanaugh, in a dissenting opinion, suggested the refund process could be “substantial” and complex.

International Reactions

The ruling has prompted reactions from international governments. The UK expressed confidence that its “privileged trading position” with the US would continue. Canada indicated it would prepare for alternative methods the US might use to impose tariffs. Germany’s chamber of commerce acknowledged the White House’s ability to impose tariffs through other legal avenues.

Looking Ahead

While the Supreme Court’s decision invalidates tariffs imposed under IEEPA, President Trump retains the authority to impose tariffs through other mechanisms. The implementation of the new 10% global tariff and potential use of Section 301 investigations will likely shape the future of US trade policy. The average US tariff rate is expected to decrease from 15.3% to 8.3% as a result of the ruling, according to Global Trade Alert.
