A U.S. federal trade court ruled Thursday that President Donald Trump's 10 percent [1] global tariffs were not justified and therefore illegal.
The decision challenges the administration's ability to unilaterally impose broad trade barriers, potentially altering the cost of imported goods and international trade relations.
The ruling was issued on May 7, 2026 [2], by a panel of federal judges in Washington, D.C. [3]. The court determined that the tariffs violated the legal framework established by the International Emergency Economic Powers Act, a trade law dating back to the 1970s [4].
According to the court, the administration failed to provide the necessary justification required by the act to implement the 10 percent [1] levy on global imports. The panel found that the tariffs did not meet the specific legal criteria needed to trigger the emergency powers granted to the executive branch [4].
The ruling marks a significant legal setback for the president's economic strategy. By declaring the tariffs illegal, the court has opened the door for businesses and trading partners to seek the removal of these duties, or the recovery of funds paid to the government [3].
Legal experts said that the decision rests on a strict interpretation of statutory authority. The court focused on whether the administration's actions aligned with the specific language of the 1970s law rather than the broader economic goals of the White House [4].
Because the ruling comes from a federal trade court, it carries substantial weight in the U.S. legal system. The administration may choose to appeal the decision to a higher court, but the current ruling stands as a formal rejection of the 10 percent [1] global tariff mandate.
“A U.S. federal trade court ruled Thursday that President Donald Trump's 10 percent global tariffs were not justified and therefore illegal.”
This ruling restricts the executive branch's power to use emergency laws for broad economic policy. By citing the International Emergency Economic Powers Act, the court has signaled that national emergency claims must be backed by specific legal justifications, preventing the president from using 1970s-era legislation as a blanket tool for global trade wars.
