A new ruling from the Court of International Trade has blocked former President Donald Trump’s plans to impose massive tariffs, sparking a bitter legal battle over the limits of the president’s emergency powers. The Trump administration immediately filed an appeal, paving the way for a constitutional fight that could stretch all the way to the Supreme Court.
Executive vs. Judicial Showdown
The court’s ruling found that Trump exceeded his legal authority by invoking the International Emergency Economic Powers Act (IEEPA) — a tool primarily used to impose financial sanctions — to enforce the new tariffs. The court stressed that the power to impose tariffs rests with Congress and that IEEPA cannot be used as an alternative avenue for setting global trade policy.
The White House issued a strong protest immediately after the ruling. Spokesperson Kush Desai said, “It is not the responsibility of unelected judges to decide how to handle a national emergency.” Meanwhile, Deputy Chief of Staff Stephen Miller called the decision “a judicial coup” and asserted that it threatened the president’s independence in emergency action.
“Liberation Day” Tariffs and the Reason for the Emergency
On April 2, Trump announced a new tariff package that he described as a “Liberation Day” policy, aimed at combating the trade deficit that he said was an “extraordinary threat” to the national economy. The package includes a base tariff of 10% on nearly all imports, along with additional tariffs ranging from 11% to 50% on about 60 target countries.
However, the plaintiffs in the case – including wine importer V.O.S. Selections and a coalition of states led by Oregon – argue that the trade deficit does not qualify as an emergency under IEEPA. They argue that using the law to impose tariffs is unconstitutional, bypassing congressional oversight.
Economic Impact and Market Reaction
Business groups and economists warn that the tariffs will hurt the U.S. economy, raising the price of consumer goods and adding to inflationary pressures. JPMorgan Chase CEO Jamie Dimon has warned that the policy could drive up prices and disrupt global supply chains.
Financial markets reacted sharply in the immediate aftermath of the tariffs. Stocks, cryptoassets and precious metals prices all moved sharply as investors reassessed global market risks.
Potential for Escalation to the Supreme Court
The appeal is currently before the Federal Circuit Court of Appeals, with the case likely to go to the Supreme Court as it involves constitutional questions about the limits of executive power in trade policymaking. In the meantime, existing tariffs based on other jurisdictions will remain in effect.
