Overview

• The lawsuit, filed in the U.S. District Court for the Northern District of California, challenges Trump's use of the International Emergency Economic Powers Act (IEEPA) to impose tariffs without congressional approval.
• California contends the tariffs, including a 10% baseline on all imports and up to 145% on Chinese goods, are unconstitutional and unprecedented under the IEEPA.
• State officials argue the tariffs are driving up consumer prices, threatening jobs, and causing billions in economic damage to California, the world’s fifth-largest economy.
• The complaint seeks to void the tariff orders and block their enforcement until Congress grants explicit approval.
• This marks the first time Governor Newsom has taken a lead role in California's legal challenges against the Trump administration, signaling a shift in his approach.
