Trump tariffs: Why is California suing the Trump administration?
California Governor Gavin Newsom sues Trump over misuse of emergency powers on tariffs, arguing it harms state businesses and families.

California Governor Gavin Newsom sued Donald Trump for misusing his emergency power on global tariffs. He asserted that the president's action is harming California families and businesses.
The lawsuit will be filed tomorrow, April 17, in federal court, alleging that Trump lacks the power to impose tariffs against Mexico, Canada, and China, its three largest trading partners. California also refuses to accept the 10% base tariff on imports from other countries.
Legal argument on the case
The lawsuit challenges Trump's decision to invoke the International Emergency Economic Powers Act (IEEPA) to impose tariffs on nations. The plaintiff claims this action was illegal and unprecedented.
In 1977, Congress granted the presidency authority to impose trade sanctions through the IEEPA. However, the Executive Branch must consult and inform Congress before taking action.
Opposition to Trump's tariffs
California Attorney General Rob Bonta says Trump's decision is disturbing and illegal. California represents the world's fifth-largest economy, and this policy is not a game, as Californians are preparing for the consequences of the president's actions.
A group of American businesses affected by the tariffs sued Trump. The lawsuit says Trump lacks the power to impose taxes authoritarianly.
