Overview
The Supreme Court on Friday ruled that the International Emergency Economic Powers Act did not authorize sweeping tariffs, Chief Justice John Roberts wrote for the majority.
President Donald Trump responded within hours by imposing a 10% global tariff and raised it to 15% less than 24 hours later, while officials said the administration will pursue other tariff authorities.
Thousands of businesses hailed the ruling and more than 100 companies have filed lawsuits seeking reimbursement, court records show.
The decision puts roughly $130 billion to $175 billion in collected tariffs at issue for refunds and adds uncertainty to U.S.-China relations ahead of Trump’s March 31 through April 2 trip, analysts said.
The administration has invoked Section 122 for temporary tariffs, is pursuing Section 301 and 232 investigations, and the Section 122 tariffs can last up to five months, trade experts said.
