The first lawsuit against Trump’s tariffs has been filed - what it claims

Florida entrepreneur Emily Ley has filed the first lawsuit against President Trump's tariffs.
The lawsuit argues that the 20 per cent tariff on Chinese goods imposed using the International Emergency Economic Powers Act of 1977 (IEEPA) is unlawful.
Ley contends that IEEPA doesn't grant the president authority to impose tariffs and that Trump's stated reason for the tariffs (trade deficit reduction) contradicts the IEEPA's intended use for emergencies.
The lawsuit seeks to have the tariffs declared unlawful and blocked.
Ley's company, Simplified, sources products from China, and she argues that the tariffs will harm American businesses and consumers.
