Overview

• California has filed a federal lawsuit challenging President Trump's use of emergency powers to impose tariffs without congressional approval.
• The lawsuit claims the International Economic Emergency Powers Act does not authorize the president to enact tariffs, making the actions unconstitutional.
• Governor Gavin Newsom and Attorney General Rob Bonta assert the tariffs are driving up costs, threatening jobs, and causing billions in economic damage to California's economy.
• The legal challenge invokes the Supreme Court’s major questions doctrine, arguing significant economic policy changes require explicit congressional authorization.
• California seeks an immediate court order to block the tariffs, which include a 10% baseline and up to 145% levies on Chinese goods, while also exploring international trade exemptions.
